refreshing on the vision, humanized design illumination differences, more help to concentrate,
improve efficiency, and many other features. The following 10 main characteristics of LED light
tube.
1, High luminous efficiency, the traditional tube light luminous efficiency is about 55-80 lm/W and
the daylight tube luminous efficiency is 72 lm/W. And LED tube luminous efficiency is above 100
lm/W. And the new LED tube, according to the testing, luminous efficiency reach 130 lm/W. And will
be improve in the future. The difference between these two kind tube have now been nearly double.
And in the near future could reach more than 3 times. 2, LED tube lighting fixture with high efficiency. The traditional daylight fixture is only about
70% efficient. The beam angel LED tube is 120 degrees, so all the light output is effectively.
Although sometimes feel light angle 120 degrees a little bit narrow, can be used in most of lighting
place. And the light angle is also can be adjustable according to need. 3, High power efficiency: because all except incandescent lamp,all lights have to match power
supply, the efficiency of the power supply will also affect the efficiency of the whole lamp. 4, Long life: A qualified LED tube life span is 50,000 hours. Life of a traditional fluorescent tube is usually only 5,000 hours (some bad traditional daylight tube working time is 300 hours). There are nearly 10 times different. 5, Do not contain mercury, no pollution. LED tube does not contain any toxic substances, is a completely green and friendly environment, no pollution light source. 6, Wide color temperature range, that can offer almost all color temperature, and also can provide for any single color, like red, green and blue. 7, High color rendering index, color rendering index of incandescent lamp is 95, the traditional daylight lamp is 65-80, and the LED lamp is > 80. 8, No UV radiation. 9, Not a glass product, not easy damaged, impact resistance, resistance to vibration. 10, LED driver can be fixed inside the tube and external. Insolation power
LED tube is the mainstream trend of indoor lighting in future. 10 major characteristics in lighting applications of LED daylight tube are acceptable by more and more consumers. Especially the light luminous efficiency is increasing fast. Energy conservation and environmental protection has been improving people’s green consciousness. LED energy conservation and environmental protection are brought to the attention of global.

9 Points to Choose LED Light Source
9 Points to Choose LED Light Source
There is very different price in the market for LED light source. As the buyer, how to choose the best cost performance LED light source? Following 9 points for assistance you making a smart choice.
1, Higher brightness, higher price. Used for LED lamp, the LED should comply with the laser level Ⅰ class standard.
2, With strong antistatic ability, LED is long life. So the price is high. Antistatic usually greater than 700 v, LED can be used for LED lighting.
3, Consistent wavelength, means consistent color. Request the same color temperature, the price is high. Even with LED spectral color separation apparatus, manufacturers are also difficult to produce highly consistent color LED.
4, Leakage current. LED is a one-way conductive lights, if there is reverse current, it is called leakage. If leakage current big, LED service life will be short. And price certainly low.
5, Different beam angle, different price. Special light beam angle, the price is higher. Such as diffuse angle.
6, Life span, Life is determined by light failure. Light failure small, means long life. Long life LED, high price will be high.
7, The lighting part of LED light source is the LED chip. Different chip, the price difference is big. Japan, USA’s LED chip generally is more expensive. Chips in Taiwan and Chian, price is lower than Japan and United States.
8, Chip, expressed as length. The bigger size, quality is better. The chip size is proportional to the price.
9, Package colloid Ordinary LED colloid is epoxy resin. With UV resistance and fireproofing agent, LED prices more expensive. High quality outdoor LED lighting should be resistant to ultraviolet light and fire.
From health into consideration, it is suggested that using non-toxic materials design. You can directly use the nose to define the quality. Good product is without bad smell. From safety considerations, the product should be dust proof, moisture proof, fire prevention, no UV, preventing low temperature cracking, relative to this LED product price is high.

How to Choose LED Panel Light
How to Choose LED Panel Light
LED panel light, with its energy saving, bright and soft light, ultra-thin, lightweight, stable and durable characteristics become popular by consumer’s favorite. They can be widely used in hotel, conference room, factory, school, hospital, housing, etc.. Which require energy saving and high color rendering index place. However, due to the price competition, LED panel light quality has the difference is big. How to identify product quality becomes problem.
Unqualified products, professional calls “bastard”, “bad goods”, “junk”, because it had broken LED energy saving, long life, environmental protection, etc. factor. Against the will of LED technology applied to our life. And seriously affected the healthy development of LED Panel light. A good quality LED panel light, should be perfectly combined with high quality LED driver, good heat dissipation structure, and high quality chip.
Energy saving key : power factor
Power factor low, means circuit design bad. It will greatly reduce the service life of light. Power factor can be tested by power factor meter. General good LED panel light power factor requires higher than 0.85. Below 0.5 is unqualified products. These products, not only lifetime short, and the actual consumption of electricity is twice higher than nominal. Haven’t the advantage of energy saving. If no “power factor meter”, there is another way is “amperemeter”. Detect two nominal power similar products, the greater current and harmonic current, the greater actual consumption. At the same time, if the currency is not stable, adverse the LED bead and the whole lamp lifetime.
Material and structure affect heat dissipation
Heat dissipation is very important to LED panel light. You have good power and LED bead, but the cooling conditions is bad. It will cause heavy light failure. Lamp life will be reduced. At present, the main heat dissipation material is copper, aluminum and PC. The best is copper, and then aluminum and PC again. For the cost performance, the first choice is aluminum. In the aluminum, the best is pin aluminum, and then lathe aluminum and casting aluminum.
LED chip company group
LED bead quality depends on the chip quality and packaging technology. Chip brand in three major groups: the first camp represented by Europe, United States, Japan’s manufacturers, mainly including Cree, osram, Nichia , toyoda gosei etc; Second camp, represented by the United States, South Korea, China Taiwan manufacturers, mainly including Preh, Epistar, Seoul, etc.; The third faction represented by China manufacturers, there are Sanan, di yuan, SilanAzure etc. Chip quality decided to the brightness of LED bead. Good LED bead, not only high brightness, but also light failure is small. High light efficiency and brightness.
LED panel light is gradually into market, and recognized by more and more people. But faced with messy products, grasp the of skills to make a wise choice, can truly bring the comfortable feeling of new light source LED.

Waht is Color Tempreture
Waht is Color Tempreture
Color temperature is a characteristic of visible light that has important applications in lighting and other fields. Color temperature is conventionally stated in the unit of absolute temperature, the kelvin, having the unit symbol K.
Absolute temperature (K) was presented in 1848 by the British physicist Keivin. He considers starting point temperature is 273.16 ℃ below zero centigrade. Absolute temperature calculation, therefore, is 273.15 ℃, combined with the Celsius temperature usually used, such as body temperature is 36 ℃, and absolute temperature 309 k.
The color temperature of a light source is the temperature of an ideal black body radiator that radiates light of comparable hue to that of the light source. Is a standard blackbody, heating temperature to a certain extent the color started from deep red to pale red – orange – white – blue and white – blue change gradually. Using this light color changing characteristic, the light from light source color hue to the light of the blackbody at the same time, we will absolute temperature blackbody was known as the color temperature of the light source. It does not make sense to speak of the color temperature of e.g. a red or a green.
Color Tempreture
Color temperature affects the atmosphere of the space. Color temperatures over 5,000K are called cool colors (blueish white), while lower color temperatures (2,700-3,000 K) are called warm colors (yellowish white through red). Under 3300k color temperature, light color has partial red phenomenon, is a kind of warm feeling to the person, above 5000k color temperature, color slants white, give a person a kind of cool feeling.
In addition, the different color temperature of light environment and medium temperature also affects the people of the surrounding environment’s color feeling. Take red light for example, under the red light source, people often cannot see the red color perfectly.
