Q:What does the LED street lamp power supply factory have?: In the domestic, is relatively well-known, R & D strength is good, but the power is not a very long time, the cost is relatively high;

Q:Road light is one of LED. How much is it?: 500 to more than 1 thousand, there are different brands, different specifications, prices vary.

Q:What are the main uses of LED street lamps?: The main application of LED street, main roads, secondary roads and branches, factories, schools, gardens, city square, Garden Road lighting.

Q:For the LED street light distribution, is it better to use a lens or a reflector?: Lens better point: the lens can be arbitrarily better match light, mold work is better than using reflective glass, the price of natural cheap

Q:The factory installed lights, with three male Aurora led, selected high power, high pitch, more: LED street light products are best seen at lumens per watt (the higher the LM value per watt, the better the performance of the chip. Many interior lighting companies like to maximize chip current. It seems the wattage, the actual lumen per watt value but not high, generally play is the best in the current 2/3 chip) such as to require the use of lights and life environment of higher products, should be at least 90lm/W lamp lumen (rather than chip value, chip should be more than 130)

Q:Is there any difference between intelligent street lamp and intelligent LED street lamp?: LED light is generally used as a light source, there is no difference between open and close appliances intelligent streetlights.

Q:What is the role of heat phase change material on a LED street light?: Mainly to play the role of heat dissipation! I don't agree with that upstairs. The heat dissipation of LED street lamp can be solved by some auxiliary things. For example, a small fan with a stronger coefficient of heat is used as a shell...... And so on, these can solve the problem of heat dissipation!

Q:Why is the higher the current, the lower the light efficiency?: Because the higher the current, according to Ohm's law, of course, the power will also increase, while the luminous efficiency is the total luminous flux / total power

Q:What are the main differences between a LED street lamp and a solar street lamp? What are the advantages and disadvantages of each?: It is two kinds of concept that do not conflict, it is the explanation of street lamp from two angles, can make LED solar energy street lamp completely.
