Q:What is the voltage of the street lamp? What about LED?
Street light voltage is generally 220V AC
Q:LED street lamp or solar street lamp?
Solar street lights are catching up with overcast weather by the possibility of insufficient power supply. The biggest problem is that it is not suitable for long-term use. Because its battery life is only 5, 6 years.
Q:What's the reason why the LED street lights don't work?
Fault phenomenon 1, all LED does not light 1), if the reason is: city power protection switch trip, hit it, and if the power is not bright, generally LED drive power failure,
Q:What is the heating temperature at the LED street lamp?
You ask this question is not clear, good heat dissipation, low temperature, poor heat dissipation, the general surface temperature is best not more than 70 degrees, each LED street lamps are not the same
Q:LED street lamps must be constant flow source? No constant current source, can I?
No, I think the LED street lamp needs DC power supply.
Q:What is the role of heat phase change material on a LED street light?
I think that a product is not only from raw material to it, but also from the process of enterprises to work on each detail can be improved, with innovative thinking to consider the product of each process! Closely grasp the quality, seize the service. Treat the product, you want to treat their children, in order to make the product to perfection!
Q:How to judge the light type of LED street lamp?
It will be tested by a large distributed photometric tester,
Q:The same brand of chips, how to judge the quality of LED lights?
Should pay attention to the cooling system for street lamp, street lamp cooling system is now divided into three types, one (die-casting aluminum (aluminum), two (three), Qi tablets) but also pay attention to the radiator is enough, there are many manufacturers have 90W heat lamps, used to install 120W to save the cost, so that his cooling system will follow no, my colleagues decay is relatively large
Q:Can you install LED street lights in your own yard?
In their own yard, you can install LED street lamps, which conforms to the national policy of promoting environmental protection and energy conservation.
Q:What heat sink is best for LED street lamp radiator?
Is natural heat dissipation, what is called natural heat dissipation, that is, rely on the lamp's own radiator to dissipate heat, and now most of the market is fin type heat sink, this advantage lies in the cost point, passive heat dissipation time. However, the disadvantage is that the heat dissipation is very slow, far less than the high-power heat dissipation requirements. Good service life is less than 2 years. But recently, the market has a kind of through-hole type heat radiation lamp, break the traditional heat dissipation concept, increased the heat dissipation surface, let the air form convection. The cooling effect is remarkable. You should be interested in discussing LED lighting technology, so you can leave a contact. I'm technical. Hope to be adopted
