LED Lights Characteristics And Advantages And Disadvantages

LED lights and conventional street lamps is different, LED light source with low voltage DC power supply, by the GaN-based power-type blue LED and yellow synthesis of high efficiency white, with high efficiency, safety, energy saving, environmental protection, long life, fast response, high color rendering index Unique advantages can be widely used in roads. Cover available production, high temperature of 135 degrees, low temperature -45 degrees.

advantage

1, its own characteristics - the one-way light, no light diffusion, to ensure the efficiency of light.

2, LED lights have a unique secondary optical design, the LED lights light to the desired lighting area, to further improve the efficiency of light to achieve energy-saving purposes.

3, LED has reached 110-130lm / W, but also a lot of room for development, the theoretical value of 360lm / W. And the luminous efficiency of high-pressure sodium lamp is increased with the power increased, therefore, the overall light effect LED street lamp than the high pressure sodium lamp; (the overall light effect is theoretically, in fact more than 250W high pressure sodium lamp light efficiency than LED lights ).

4, LED lights light color than high pressure sodium lamp much higher, high pressure sodium lamp color rendering index is only 23 or so, and LED street light color rendering index of 75 or more, from the visual psychological point of view, to achieve the same brightness, LED lights, the average light Than the high pressure sodium lamp by more than 20%.

5, light fades small, less than 3% of the light of one year, the use of 10 years still meet the road requirements, and high pressure sodium lamp decline, about a year has fallen more than 30%, therefore, LED lights in the use of power design Can be lower than the high pressure sodium lamp.

6, LED lights have automatic control of energy-saving devices, to meet the lighting requirements in different circumstances to meet the maximum possible reduction in power, saving energy. Can achieve computer dimming, sub-time control, light control, temperature control, automatic inspection and other user-friendly features.

7, long life: can use more than 50,000 hours, providing three years of quality assurance. The downside is that the life of the power supply is not guaranteed.

8, high luminous efficiency: ≥ 100LM above the chip, compared to the traditional high pressure sodium lamp can save more than 75%.

9, easy to install: no need to add the cable without rectifier, etc., will be installed directly on the pole or the original light source nested lamp shell.

10, excellent heat control: summer temperature control below 45 degrees, and the use of passive cooling, summer heat protection.

11, reliable quality: all the use of high-quality circuit components, each LED has a separate over-current protection, no need to worry about damage.

12, light color uniformity: no lens, not to improve the brightness at the expense of uniform light color, so as to ensure that no aperture light color uniform.

13, LED does not contain harmful metal mercury, in the retirement will not cause harm to the environment.

Combined with the above principles of energy-saving effect is remarkable, instead of high-pressure sodium lamp can save more than 60%.

Low maintenance costs: Compared to traditional street lamps, LED lights maintenance costs are very low, after comparison, less than 6 years to recover all the input costs.

Disadvantages

1, a single LED power is low. In order to obtain high power, multiple parallel use is required.

2, low color rendering. In the LED display under the color of the incandescent lamp is not true, which from the spectral distribution of the analysis, are technical issues.

3, spot. As the white LED manufacturing process defects with the reflective cup or lens with the error, likely to cause "yellow circle" problem.

4, LED irradiation uniformity problem. If you do not carry out the second optical design, LED irradiation is more concentrated, so be sure to carry out the second optical design, so that the light intensity distribution was bat-shaped.

5, LED light failure problem. Compared to low-power LED, high-power LED lights will be much better light failure. But the small power LED heat dissipation is very small. And high-power LED is there is no way to solve the problem of heat, and heat will be significantly reduced after the brightness, so the power can not be bigger. Now the market sales of Spark LED lights is the largest 360W.
