The development of solar powered LED street lights
Focus on new technology development. Such as the solar powered LED street lights internal quantum efficiency enhancement, as well as changes in package structure and new phosphor / quantum dots, the transparent substrate, contact materials, reflective materials, the second optical / lighting reflector¡¯s design, and development of high-performance drive power .
OLED challenges can not be ignored. Solar powered LED street lights and OLED have their own strengths, when the LED high bay lighting market, but also face the competition of ¡°compatriots¡± OLED. OLED display technology has been relatively mature, and has entered the market, lighting technology is taken seriously, in the rapid development of. The commercial grade white OLED light efficiency reached 50lm / W general lighting lights more than two times the life expectancy has reached 100,000 hours. And laboratory research and development of white light emitting efficiency of 120lm / W, is close to the U.S. Department of Energy requirements for lighting materials 150lm / W. Of course, OLED flat light source is also facing some problems: poor antioxidant capacity of the OLED light-emitting materials, power, afraid of the water, you need to vacuum glass seal, so need LTPSTFT substrate, OLED applications in the field of large-size the cost will be high; the yield of large-size OLED panels are still not high, a substantial increase in the cost of OLED product line, but also makes the production can not improve quickly; light-emitting material properties, component life by the effects of restrictions of the short board; surface light source specifications and drive power standard is yet to be established.
Common faults for led solar street lighting system
The first case for the instrument panel of the led solar street lighting system is lit, there are two possibilities, an insufficient amount of oil the engine cannot be the complete lubrication of oil, under normal circumstances, the oil does not consume a lot of, so there may be leakage of engine oil. The second oil pump pressure and you should as soon as possible to stop to avoid traffic continue to operate without oil lubrication conditions resulting in engine damage.

The second scenario is the dashboard of water level lights, due to the water tank is not no reason to reduce cooling system problem occurs, there are two possibilities, first, somewhere in the system water leakage, and second, the temperature is too high The led solar street lighting system pressure water squeezed out. If the tank leaks can be temporarily to the vice water tank, add water, and then try to open a nearby repair shop technician handling. The location of the vehicle with various sub tank is not the same, it is recommended that the owners should refer to the owner¡¯s manual. Keep in mind is that due to high engine temperature, do not easily open the radiator cap in order to avoid the instant the smoke vapor damage.
If the water temperature of led high bay lights Quefei above, the heat with the cooling fan must immediately stop driving, or the temperature suddenly rose, and pressure change stool causes the coolant into a high-pressure steam from leaking out, and also led to the engine cylinder head deformation or cylinder head gasket is damaged, the vehicles that would take 1-2 days to repair.
