How to Matainance LED Lighting
How to Matainance LED Lighting
Today, more and more families began to use LED lamps, mainly home use LED ceiling lamps , LED bulb , LED downlight , LED ceiling lamp , etc. , LED lamps with energy-saving , environmental protection , long life and celebrated, but If used improperly , LED lamps will wear out and fail , thus affecting the life of LED lamps , therefore , LED lighting maintenance is also the concerns of consumers.
1 , first when looking to buy a quality assurance brand, for some consumers to seek cheaper , to buy some products of inferior quality home, that life is certainly not long .
2 , buy LED lamps after installation, take a look at the product installation manual , follow the instructions to install the fixture , be careful not freely change the lamp parts, not missing equipment, the wrong equipment lighting components.
3, some LED lighting , such as LED bulb , LED flood light , LED candle lights, the lighting for some time, there will be an outer wall lamp drops , mist phenomenon. Why ? Because the LED lamp is composed of several different materials , such as acrylic material mask is generally used , cooling part is a metal fixture at work generates some heat , different materials will have different coefficients of thermal expansion of different materials used for a long will have a gap junction , there will be air to enter, when the LED lamps in the humidity is relatively large in the work environment , there will be water vapor into the fixture , then it will produce mist and droplets of the phenomenon, and humid environment will affect the drive power to the LED lamp electronic components , thus affecting the life of LED lamps , so in wet environments , such as toilet , bathroom, Chufang damp shade should be installed to prevent moisture carry lamps , causing damage or rust leakage circuit phenomenon.
4, the use of LED lights , you should try to avoid frequent switching , because the light is turned on at the moment, will produce a large current will cause excessive current LED driver power supply part of the components burned, or breakdown, thus affecting lamp life , although the number of LED lamps switch resistance is 18 times that of ordinary fluorescent lamps , but we still have to try to make little switch.
5, LED lamps do not use water to clean as much as possible , simply wipe with a dry cloth dipped in water .

LED Education
What are LEDs?
LED stands for Light Emitting Diode. It is a semiconductor device similar to diodes used in every day electronics, with the exception that when a current flows through a LED, light is created at the light emitting diode’s junction. There are two basic types of LEDs: conventional and high flux.
Conventional LEDs are typically packaged in 3mm or 5mm packages and are used for indicator lights on everything from computers to appliances to automobiles.
High Flux LEDs are used to provide high intensity light sources for traffic signals, flashlights, building lighting and other architectural lighting applications.
Do LEDs get hot?
Yes they do. A popular misconception is that LEDs are cool. In fact, although they are more efficient than many other light sources, LEDs waste about 80% of their input energy as heat. What makes LED light fixtures more of a design challenge is that this heat is created at the heart of the LED (in its P-N junction). Effectively removing that heat is what differentiates a well designed lighting fixture which will perform well over time. For this reason, many of the same techniques that are used to cool computer chips, such as heat sinks, are being applied to LEDs.
Can LEDs run off AC power?
Not directly. The voltage required to run an LED is typically between 3 and 4 volts DC (about the output of 2 household batteries). Furthermore, LEDs are polar devices which means that they only conduct current in one direction. In order to operate LEDs from AC power, a converter circuit, called a driver is required. This driver converts the high AC voltage to a lower DC voltage with a constant current. It should be noted that there are some “so-called” AC LEDs but these are basically LEDs configured as a rectifier to allow connection directly to the AC line. The other limitation for “AC LEDs” is that they only emit light when current is flowing in one direction, and therefore, only output 50% as much light.
How long will LEDs last?
Unlike conventional incandescent bulbs which fail catastrophically after about 1000 hours, LEDs will typically last 30,000 to 50,000 hours or more with only a 30% reduction in light output. However, this lifetime is highly dependent on how hard the LEDs are driven as well as how well the heat is removed from the device. Additionally, the lifetime can also be affected by how the LEDs are handled during the assembly process as well as the environment under which they operate in the field. While LEDs normally just experience a reduction in light output as they age, it is possible for them to fail catastrophically if they are not used properly or are of poor quality.
What colors do LEDs come in?
LEDs are offered in a number of colors from the various manufacturers. Typically they are offered in Royal Blue, Blue, Cyan, Green, Amber, Red-Orange, Red and White. In addition, there are ultraviolet and infrared LEDs for special applications. There are also multi chip packages available with combinations of various single-color dice which can be used in combination to create a wide range of colors.
What are “cool” white LEDs?
Most white LEDs are actually blue LEDs to which manufacturers add a yellow phosphor which, when combined with the blue light, produces a white appearing light output. In some cases manufacturers also add a second red phosphor to provide a light spectrum which more closely matches the output of an incandescent light or the light from the sun. These LEDs are usually referred to as “warm” white LEDs. Recently a third category of LEDs have been added known as “neutral” white. These LEDs typically fall between “cool” and “warm” spectra.

4 Key Points in Design LED Outdoor Lighting
4 Key Points in Design LED Outdoor Lighting
LED Outdoor lighting design should comply with the latest outdoor lighting technical specifications, as well as the city lighting design standard.
1, Working Environment
The working environment of outdoor lighting is tough, like wind, rain, sunshine, the ultraviolet radiation, the temperature changes, dust, chemical gas influence, and year by year aging treatment by nature. We should fully consider the impact of these factors before design.
2, Structure Design
Heat sink is generally chose aluminum or aluminum alloy, copper or copper alloys, and other alloy with good heat conduction. The cooling way like cooling air convection heat, wind cooling heat and heat pipe cooling, (jet cooling heat dissipation is similar to a heat pipe cooling, but more complicated structure) Choose what kind of cooling mode has a direct impact on the cost of the light, should be more considered.
Now we use transparent organic glass, PC material, etc., traditional chimney is transparent glass products. The best choice for chimney of outdoor lighting is traditional glass products, it is the best choice making the long life and high-grade lighting. The transparent plastic, organic glass, etc materials do chimney, it’s better to do the chimney of indoor lighting. If used it for outdoor, the life is limited. Due to the outdoor sunlight, ultraviolet ray, sand and dust, chemical gases, day and night temperature change and other factors. At the same time the pollution is not easy to settle accounts clean, make lampshade transparency reduced light output.
3, LED Chip Package
Current LED outdoor lighting (mainly street lamp) are mostly use 1 w LED more series and parallel for assembly, this kind of method thermal resistance advanced packaging technology products is high, not easy to create high quality lighting. And another way is to use 30 w, 50w even greater module for assembly, in order to achieve the required power, these LED encapsulation materials useful epoxy resin encapsulation, useful silica gel encapsulated. The difference is: epoxy resin encapsulation heat resistance is poorer, time is long aging. Silica gel encapsulation is heat resistance is good.
More chips and radiator whole package is better, or use the aluminum plate more chip package again through the phase change material or heat silicone grease and radiator connected, make product thermal resistance than using LED device assembly product thermal resistance is less one or two word thermal resistance, and will be more suitable for heat dissipation. The LED module lighting, module base plate is commonly copper base plate, it to the radiator of the connection to use good phase change material, or good heat dissipation silicone grease, guarantee the copper base plate of heat can promptly to the radiator up, such as processing is not easy to make heat accumulation cause module chip is too hot, influence the normal work of the LED chip. The author thinks that: chip packages suitable for manufacturing general lighting lighting, module encapsulation limited space for the occasion of manufacturing compact led lighting (such as car main lighting head lamp, etc.).
4, Design of Radiator
The radiator is one of the crucial parts of LED lighting, its shape, volume, heat dissipation surface area are designed to address the benefits. If radiator is too small, LED lighting working temperature is too high, influence the luminous efficiency and life. If radiator is too large, the consumable material increase product cost and weight, make the product competition force down. Design the suitable LED lighting radiator design has the following 7 parts:
1. Understand the need of power for LED lighting cooling.
2. Some parameters when designing radiator: metal heat, the thermal conductivity of metal, chip thermal resistance, thermal resistance, the surrounding environment air thermal resistance, etc.
3. Determine the type of the heat dissipation, (natural convection, wind cooling, heat pipe cooling, and other cooling mode. From the cost comparison: natural convection cost minimum, wind cooling medium, heat pipe cooling cost is higher, jet refrigeration highest cost.
4. Define LED lighting licensing the highest working temperature (environment temperature and lighting licensing temperature rise)
5. Calculating the volume of radiator, radiator area. And make sure the shape of the radiator.
6. The radiator and LED lighting sets synthetic complete lighting, and energizing work more than eight hours at room temperature, 39 ℃ – and ℃ environment check the temperature of the lighting, look to whether meet the cooling requirement, in order to check calculation is correct, such as do not satisfy the conditions of use, should recount and adjusting parameters.
7. The radiator and lamp shade seal to do waterproof, dustproof, chimney and the radiator to pad anti-aging rubber pad or silicone rubber pad, with stainless steel bolts and do seal waterproof, dustproof.

LED light with many advantages because it is environmentally friendly, long life, high photoelectric efficiency (luminous efficiency more than 130LM / W), seismic and other applications in various industries in recent years rapid development, theoretically, LED service life of 100,000 hours, but in the practical application of the process, some LED lighting designers of LED drive power a lack of knowledge or improper selection or the blind pursuit of low-cost, results greatly shorten product life LED lamps poor LED lamp life of less than 2,000 hours, and some even more low, the result that the advantages of LED lamps are not a very good play. Because of the particularity of LED manufacturing, leading to different manufacturers and even with a production factory in the same batch of products produced by the LED current-voltage characteristics are individual differences. Now a high-power 1W white LED typical specifications, for example, the LED current, the voltage variation to do a brief description of the general 1W white light application forward voltage of 3.0-3.6V, that is, when the nominal 1W LED flowing through the 350 mA current, the voltage across it may 3.1V, may also be in the 3.2V or 3.5V may be other values, to guarantee 1W LED the life, the general LED lighting manufacturer recommends factory with 350mA current drive through across the LED forward current of 350 mA, the forward voltage of the LED at both ends of a small increase in the LED forward current substantial rise in the LED temperature into a straight up, thus speeding up the LED light failure shortened life expectancy, the LED, serious and even burn out LED. Due to the particularity of the LED voltage and current changes, and therefore the power of the LED drive strict requirements. LED drive power LED lamps, it is like a person’s heart, to the manufacture of high quality, LED lamps for lighting must give up the constant voltage drive LEDs. Now many of the high-power LED packaging factory many pieces of a single LED through parallel and series are sealed together to produce a single 20W, 30W or 50W or 100W or higher power LEDs, despite the package before the single LED are strictly selected and paired the internal quantity ranging from dozens of stars, more than a few hundred monomers LED, high power LED products packaged in voltage and current, still there is a big difference, and phase than a single LED (usually a single white, green, blue, operating voltage in the 2.7-4V, single red, yellow, orange voltage of 1.7-2.5V) parameter bigger difference! Many manufacturers of LED light products (such as guardrails, lamp cup, projection lamps, garden lights, etc.), resistance, Yung Buck, and then add a Zener diode voltage regulator to the LED power supply, drive LED there is a great defect, The first is the low efficiency, consume large amounts of power in the dropping resistor, there may even exceed the power consumed by the LED, and can not provide a large current drive, because the greater the current, the electrical energy consumed at the Buck resistor greater, can not be guaranteed by the LED current does not exceed their normal work requirements, design products will be lower across the LED voltage supply drive, so at the expense of price LED brightness. Using resistance, Yung Buck driving the LED, the brightness of the LED can not be stable, when the supply voltage is low, the LED brightness dimmed, the power supply voltage is high, the brightness of the LED brighter. Of course, resistance, Yung Buck drive LED biggest advantage is low cost, is still part of the LED lighting business in this way. Some manufacturers, in order to reduce the cost of the product, constant voltage drive LED also brought mass production LED brightness uneven LED does not work in the best state of a series of Q Constant current source driver is the best LED driver, constant current source driver, without limiting resistor in series in the output circuit LEDs flowing through the current is not subject to changes in the external power supply voltage, ambient temperature changes, as well as the discrete nature of the LED parameters effects, thereby maintaining a constant current, and fully play a variety of excellent characteristics of the LED. LED constant current power supply to the LED lamps will automatically detect and control the flow of power during the LED current, therefore, do not have to worry about excessive current flows through the LED in the power of the moment, do not have to worry about the load short burn out the power. Constant current drive, it can avoid the LED forward voltage change due to the current changes in the constant current LED brightness stability, easy LED lamp factory implementation of mass production, to ensure product consistency, so many manufacturers have fully aware of the importance of the drive power, many LED lamp manufacturers have abandoned a constant voltage mode, choose a slightly higher cost constant current to drive the LED lamps. Some manufacturers fear the power driver board selected the electrolytic capacitor will affect the life of the power, in fact, is a misunderstanding, such as: If I choose to 105 degrees, and the life expectancy of 8000 hours of high-temperature electrolytic capacitors, electrolytic capacitor life estimation method prevailing “Every 10 degrees lower doubling of life expectancy, it is the working life of 16,000 hours, in an environment of 95 degrees in the working life of 32,000 hours in 85-degree environment, the working life of 64,000 hours in 75-degree environment, if the actual work at lower temperatures, life will be longer! Seen in this light, as long as the selection of high-quality electrolytic capacitor drive power of life is not what effect! It is also worth LED lighting business Note: Because the LED will release a lot of heat in the course of their work, so that the junction temperature of the die to the rapid rise in the LED higher the power, the greater the heating effect. LED chip temperature rise will lead to a light-emitting device performance attenuation changes in electro-optical conversion efficiency, even when serious failure, according to the experimental test: LED temperature increase of 5 degrees Celsius, the luminous flux decreased by 3%, so LED lamps must pay attention to the heat of the LED light source, in the case of possible Operating Temperature increase the cooling area of the LED light source as much as possible, try to reduce the operating temperature of the LED itself, if conditions permit, it is best to be able to power part of the light source partially separated, blindly pursue small volume and neglect lamps and power is undesirable ‘s.

Do LED Lights Hurt your Health?
Do LED Lights Hurt your Health?
Find the answer to the frequently asked LED lights related question: Do LED Lights Hurt your Health?
Because there has been so much bad press in recent years about certain types of light causing cancer, many concerned consumers are questioning, Do LED Lights cause cancer? The answer is a bit complex, but in general it is safe to say that there is no evidence to support this. LED lights have not been found, in any studies, to cause cancer. The main cause of cancer in any light source seems to come from exposure to UV radiation and hazardous chemicals that may be found in incandescent and fluorescent light bulbs. LED lights neither contain mercury nor do they emit ultra violet rays, making them a less likely candidate to cause illness, when compared to light sources that do contain cancer causing attributes.
Cancer Causing Agents and Incandescent Bulbs
Incandescent bulbs deliver ultra violet rays, even if not in large amounts, these rays can contribute to cancer. In addition to ultra violet rays, there are many other vapors and gasses that are omitted by incandescent light bulbs. These vapors have not been proven to cause cancer; however, they have been proven to contribute to a number of different illnesses. For these reasons alone, LED lights have been proven to be much safer.
Fluorescent Bulbs in Relation to Cancer
Not only do fluorescent lights deliver ultra violet rays that have been proven to cause cancer, but, they also contain mercury which can cause a number of other health issues, such as headaches, fatigue, and dizziness. In addition, recent studies have shown that prolonged exposure to fluorescent lighting can lead to an increase in a hormone called cortisol. When too much of this hormone is released into the body, several consequences may occur, including the body storing an over abundance of belly fat. This has led researchers to note a correlation between fluorescent lighting and colorectal cancer.
Lights, the Environment and Cancer
When asking the question, Do LED lights cause cancer? It is essential to understand various forms of cancer in terms of UV radiation and why we are at such increased risk from these harmful rays. Of all the sources of artificial light, LED lights are least likely to play a role in contributing to the risk of cancer. Because they utilize such a small amount of power to operate, they have an extremely tiny carbon footprint. Less damage is done to the ozone, which in turn helps to protect against an overabundance of naturally occurring UV radiation from the sun. So in effect, when seeking to determine, Do LED lights cause cancer? The best answer is, they probably even help to guard against it!
LED lights are not only healthier for human being, but they are also much healthier for all life forms, and the very planet on which we live. It is a straightforward matter to transition from conventional light bulbs to safer LED lights which can be found in local retail stores as well as online. When seeking to transition an entire household or place of employment, shopping online would provide the most cost effective way of doing so as it is easier to find discounts on bulk orders.

Lighting Basic Knowledge
Lighting Basic Knowledge
Lighting is the most decorative items that can affect the family environment, because it affects our lives in varying degrees. Different forms of lighting around the object or space image, color, and they give the impression. The lighting cannot only create but also can break the atmosphere of the indoor environment.
However, the reality is often the case: the architectural style and structural design has been completed and put into the building implementation, when people think of the lighting. This is a big mistake. Lighting and other factors, like I need from initial design and consideration. Especially residential owners at least the basic knowledge of lighting design, in order to come up with their own views to residential lighting design. It is regrettable that many architects, interior designers and decorative construction management personnel, lack of training in this area.
In the past decade, there has been a lot of new technology and thus know the principles of design it is very necessary. If the socket and bulb, then the market is only set in Hua board, who faces lighting expertise? But now, home from a wide variety of lighting fixtures to choose (the lighting device refers to a full range of lighting equipment, including all installation and energized parts), fluorescent lighting alone experienced a revolutionary change, both for conservation energy, but also to inherit the style of the architectural traditions, fluorescent lighting has now become an essential component of the interior decoration.
Today, people’s lives and entertainment have changed, countless homes have adopted the open design. This design provides an effective support for conversion of the function of the room. The modern entertainment center and control system have also changed the way people use residential. Excellent lighting design should be all the diverse needs of the occupants and their way of life to consider including.
1, Lighting Basic Knowledge: Lighting Functions
When planning residential lighting should focus on the use of different types of lighting fixtures to meet the following three elements of the light needs: people, architecture and key items, such as works of art, collectibles. These three elements are important, but the most important is to consider how people use the cellar lighting.
2, Background lighting: to make the space more user-friendly
Light of the background lighting to make the room filled with soft, enchanting light, so that the space user-friendly. Ideal background light, contemporary lighting design with a reflective light from the walls and ceiling, so that you can minimize the bright spot, the light will not cast a shadow on the faces of the people, so as to achieve a satisfactory lighting effects. The background lighting from the wall lamp, chandelier, or the height of the cabinets, beams and other light sources.
3, Decorative lighting: the glorious glow of lighting fixtures
Ornate chandeliers, the task of the shape of candlestick wall lamp so that the surface of the irradiated flashing to show off, causing the background light to the room the illusion of edge lighting shall be structured auxiliary lighting as a foil, because if the decorative lighting fixtures as the room all The light will make the entire space is too bright.
4, Accent lighting: strengthen prominent light
Accent lighting with carefully arranged more concentrated beam irradiation objects, works of art, bonsai or some architectural detail structure. The main purpose is to achieve the artistic effect. The focus of the camera’s design is often to make viewers think that the light is less bright light source, such as candles or wall chandelier. Embedded adjustable lighting, track lighting or mobile lighting fixtures can provide accent lighting light.
5, Lighting: lighting fixtures designed specifically for the desk
Task lighting is needed people to do more with eye-work or activity is very focussed, high-brightness light illumination. Like the study of commonly used lamps, table lamps, installed in the cabinet below the long strip lights, or vertical placement of the bathroom mirror on both sides of the elongated strip lighting can provide task lighting.

Idea for LED Bulb
Led bulbs are economic type and environmental friendly. Different types of bulbs are available in the market. When one want to choose these bulbs certain things he has to keep in mind. First he has to decide about the brightness requirement. He can use wattage for comparing. The new method of comparing bulbs is lumens. The higher the lumens the brighter the bulb will be.
The ideal one for task lighting is the new LED bulbs with cool white light. The warm light is generally used for small and accent area lighting. For recessed or track lighting various types of LED bulbs with standard Screw bases or pin sockets are available in the market. Standard and dimmable bulbs are also available for selection. Choosing high quality bulb is important because other cheap varieties will fail easily. Looking for certification is also very important.
Diffused bulbs: This type of LED bulbs is clusters of LED bulbs covered by dimpled lens. This spreads the light for a wide area. These bulbs available with standard Edison bases are used for many purposes. These bulbs are used for lighting porches, rooms, accent lamps, reading lamps, hallways and for low lighting area where it can be used for long periods.
Diffused type of high power bulbs: This is designed for common household use. The light produced by these bulbs is equal to that of a 100W incandescent bulb. The EvolLux and Zeal Lux are first FCC approved and first UL listed LED bulbs for general household lighting.
Track Lighting: These bulbs are available inMR-16 (pin based) that is good for track lighting. These LEDs don’t produce heat even if they are on for a long time. The bulbs are not hot to touch. Since they are 90% more efficient than the ordinary incandescent and the life is ten times more than that of CFL. So the frequent change of bulbs is reduced.
Recessed Spotlight and Down light bulbs: Now these LED bulbs are obtainable for standard lower-level lighting pots and for household purposes. The power output and color quality are the same as incandescent down lights, but power consumption is very less. These are also durable and long lasting.
Outdoor Floodlight LEDS: Energy sucking halogen bulbs are used for outdoor lights and security lights. Sometimes CFL bulbs are used that are spoiled quickly when installed in switches of motion activated type. These are replaced by LEDs, which is energy efficient. But these bulbs are not as dazzling as halogen bulbs. The given details will help a person to choose his LED bulbs according to his choice
