about LED

LED lights spot lights selection is also a noteworthy factor. In the development of road lighting, there is a comparison of the use of yellow and white. Yellow is now the mainstream of high-pressure sodium lamp, because of its economic energy, while they have excellent through fog performance, so the street selection of our mainstream. Nevertheless, the yellow light, but also has its deficiencies: that is the color reproduction is poor. People feel that way, sodium lights, the illuminated colors are yellow and distortion. The pursuit of white light is natural sunlight. Because it has the best color performance, while the sun is a warm white light. So, If you can do and similar to daylight white light, while to take into account energy-saving advantages of yellow, it would be the ideal selection of lighting at night. The early stage of white light is a metal halide lamp, although it has the ability to perform than the yellow color over several times higher, but through the fog of poor performance, low useful life are difficult to overcome technical problems and has not been large-scale application. LED light(Светодиодные Трубки) source production can compensate for this shortcoming. Choice of LED light source's color temperature 3500K or so more appropriate to meet the lighting requirements in photopic vision and comfort. Is feasible, but also in the development of today's LED down light effect on the cost and large area suitable for Flat led panel lights. Above 6000K white street light held different views, especially over high-power 160W, a cautious attitude in the fast road use. National standards for road lighting, highway, trunk road must be cut-off light type or half light lamps. Cut - Off Lighting The maximum intensity direction and lighting of lamps down the vertical axis angle from 0 ° to 65 °, an angle of 90 ° and 80 ° angle to the direction of the light intensity, the maximum allowable value for 10cd/1000lm and 30cd/1000lm lamps. And regardless of the size of the light flux, the light intensity in a 90 ° angle to the direction of the maximum value shall not exceed 1000cd. Half of the light type fixtures The maximum intensity direction and lighting of lamps down the vertical axis angle between 0 ° ~ 75 °, an angle of 90 ° and 80 ° angle to the direction of the light intensity, the maximum allowable value of the lamp is 50cd/1000lm and 100cd/1000lm. And regardless of the size of the light flux, the light intensity in a 90 ° angle to the direction of the maximum value shall not exceed 1000cd. Expressway road, road width, traffic is heavy, fast speed, visual acuity requirements. Brightness uniformity of illuminance, color temperature, on the road, glare indicator. In order to 400W high pressure sodium than blindly to the requirements of high power, high brightness. And LED today regardless of the luminous efficiency or have difficulty in cooling costs, cost-effective on the promotion difficult.

LED street lamp design

LED and traditional lighting, it has a point light source, high brightness, narrow-beam output. Therefore, the designers of the new candle energy saving lamp will be put forward higher requirements. LED street lamp first to consider the full use of the limited luminous flux to the effective illuminated area. The street light requirements for road lighting, open space beyond the road is not the way of street lighting. Therefore, effective control of light distribution, so that the LED ceiling lighting emitted as a long strip of the band of light along the surface direction spreading, while taking care of the glare generation in the azimuth of the driver to watch the lighting, lamps at 80 ° and 90 ° elevation angle direction of the light intensity shall not exceed 30cd/1000lm and 10cd/1000lm and regardless of the size of the light flux, the intensity maxima in a 90 ° angle to the direction shall not exceed 1000cd. Therefore, if the light angle without strict control will have a strong glare, high brightness LED products and even the body will cause a certain amount of optical radiation hazards. Street lighting is a systematic project, to do a reasonable light distribution difference between semiconductor lights must first clear understanding of the road lighting standards and requirements of conventional lighting with light principle, the spherical surface of the reflection of light and point light source, the pros and cons complement each other, give full play to the advantages of the LED light source beam angle controllability advantages of long life and cold light source. On the structure of the semiconductor 220V LED Spot Lamp source has its own characteristics and optical properties, semiconductor lights should be in accordance with these design characteristics of lamps, the wick of some manufacturers today using the traditional lamp shell of another semiconductor transition conduction cooling is to make a good lamp. The problem is that the external shape of the lamp body to combine the light-emitting tube heat while cooling depend on the area, the surface area of the existing conventional lighting is not enough Joule heat law "is to have a good natural air convection environment. The operating temperature of the LED products basic to control below 65 ℃ (International Standard is 80 ℃, LED working temperature reaches 85 ℃, the luminous flux will drop by half; longer wavelength, ie, redshift; more than 90 ℃ is burned) . LED installation, scientific and reasonable optical light distribution, light body sealing is very important. At the same time, the design of the lamp structure but also conducive to high-volume industrial production. The cooling of the LED semiconductor light to the focus on resolving the problem. LED cold light source, unlike the gas discharge lamp as a searing heat, but the limitations of today's LED LED luminous efficiency heat its temperature capabilities are limited, so the heat must be generated in the LED work released into the air, ensuring LED work in a safe temperature, so that the semiconductor light in order to truly reflect the advantages of long life. LED tube lamps selection of LED is very important, some manufacturers use single integrated package 10W, combined production of street lights, there are optical light distribution difficult, prone to glare, the overall cooling difficulties defects. For useful 3W to 5W module, LED meter-per-watt light efficiency is low, there are also the overall heat dissipation problem, the same luminous flux compared with the single 1W price advantage is not obvious. Taken together, the selection of high-power 1W LED is more reasonable. Luminous efficiency, 1W high level of high-power LED technology for lighting, energy-saving advantages are obvious, the current selection of 1W to do the street light is more reasonable.

Ordinary fluorescent lamps and LED fluorescent

Fluorescent light at each end of a filament lamp is filled with traces of argon and thin mercury vapor, the tube wall is coated with a fluorescent powder, the gas between the two filament    LED light applications Body electrical conductivity when ultraviolet light, the phosphor glows softly with visible light. Fluorescent work characteristics: lamp began to light requires a high voltage, normal light allowed to pass through small current when the lamp at both ends of the voltage below the supply voltage.

Both ends of the fluorescent tube is equipped with the filament, the glass tube wall is coated with a thin uniform layer of phosphor LED tube has been pumped into the degree of vacuum of 10-3-10-4 mm Hg, a small amount of inert gas filled, but also inject trace liquid mercury. Magnetic Ballast is an iron-core inductor coils, the nature of the inductance when the coil current changes in the coil will cause flux changes, resulting in the induced electromotive force, the direction of current in the opposite direction, thereby preventing with current changes.

Starter switch from the role in the circuit, it is a neon discharge tube and a capacitor in parallel from the role of capacitance to eliminate the power of the electromagnetic interference and vibration Tang loop formation with the ballast to increase the start pulse voltage amplitude . An electrode discharge tube in the bimetal, the use of neon bulb and discharge heating, the bimetal to open and close, causing the inductor ballast current mutation generates a high voltage pulse added to the tube at both ends. Began to glow discharge between two electrodes after when fluorescent Access circuit, starter, so that the bimetal thermal expansion of the polar contact with the static contact, so the power supply, ballast filament and from the hui to form a closed loop, the current the filament warm-up, when the heating time of 1-3 seconds, the glow discharge between two electrodes of the starter off, followed by the bimetallic strip cooling very disconnected with the static contact, the moment when the two electrodes is disconnected current in the circuit suddenly disappeared, so the ballast generates a high voltage pulse superimposed with power added to the tube at both ends, so that the inert gas within the lamp ionization caused by the arc discharge in normal light-emitting process, ballast self-inductance of the device also plays the role of the stabilizing circuit current. LED Down Light fluorescent

led fluorescent light to high quality, durable, energy-saving as the main characteristics, the projection angle adjustment range 15W brightness equivalent to ordinary 40W fluorescent lamp. Resistant to high temperatures, moisture and waterproof, leakproof. The use of voltage: 110V, 220V optional jacket optional glass or PC material. Lamp with the ordinary fluorescent lamp. LED fluorescent light using the latest LED technology, digitized designs, saving up to 70%, 12W LED fluorescent light intensity fluorescent tubes (equivalent to 40W for the ballast and starter consumption of 36W fluorescent electricity consumption is 42W to 44W). LED fluorescent lamp life 10 times more than ordinary lamp, virtually maintenance free, no need to frequently replace the lamp, ballast, starter. Green semiconductor light source, light and soft, pure spectrum is conducive to the protection and physical health of the user's vision. 6000K cool white light and gives a visual cool feeling, humane illumination differences in design, but also help to focus and improve efficiency. At present, LED fluorescent and fluorescent contrast, the following advantages: 1, energy-saving. 2, long life. 3, applicability, due to the small size of the single LED, can be made into any shape. 4, short response time, ns (nanosecond) level of response time, and ordinary lamps is the level of response time in ms (milliseconds). Environmental protection, hazardous metal waste recycling easy. 6, colorful, luminous, pure color, a narrow spectral range, and through the RGB three primary colors blending into a colorful or white. Disadvantages: expensive. 2, the light efficiency and the theoretical light efficiency generally do a big gap. 3, is able to do the life and theory of life (10w hour) there is a big gap. 4, there are still a certain amount of heat. 5, the light fades can also be narrowed significantly.

                                  However, these shortcomings can be overcome through process improvements, so even if the china LED strip light source can not completely replace the existing conventional light sources, but as technology evolves, the future is dominated by the LED.

About LED

LED (Light Emitting Diode), light emitting diode, is a solid state semiconductor devices, which can be converted directly into electricity for light. The heart of the LED is a semiconductor chip,

             LED light  chip attached to one end on a bracket, one end is negative, the other end to connect the positive power supply so that the whole chip to be epoxy encapsulated. The semiconductor chip consists of two parts, the part of the P-type semiconductor, the dominant hole in it, the other end of the N-type semiconductor, here is mainly electronic. But when two semiconductor connected to form a PN junction between them. When the current through the wire to the chip, the electrons would be pushed to the P region in the P region electron-hole recombination, and then will be issued in the form of photon energy, which is the principle of LED light. The wavelength of light is the color of light is determined by the material to form a PN junction.

          The initial LED as the light of the instructions of the instrumentation, then a variety of light-colored LEDs in traffic lights and a large area display a wide range of applications, resulting in a good economic and social benefits. To 12 inches of red traffic lights, for example, in the United States was long-lived, low-efficiency 140-watt incandescent lamp as a light source, it produces 2000 lumens of white light. The red filter, the light loss of 90%, leaving only 200 lumens of red light. In the light of the new design, Lumileds uses 18 red Led Tube source, including circuit losses, the total power consumption of 14 watts to produce the same luminous efficiency. The car lights are also an important area of the LED light source applications.

For general lighting, people need a white light source. 1998 white light LED development. The LED is packaged together to make the GaN chip and yttrium aluminum garnet (YAG).
