FAQ

LED street lights are different from high pressure sodium lamps (both street lamps), as well as superior power consumption
The color temperature of LED street lamp is high, the color rendering is very good, the visual effect is better than that of sodium lamp. In theory, it saves electricity and lives longer than the high pressure sodium lamp, and the luminous efficiency of high pressure sodium lamp is very high, and the light penetration is very strong and the life is long
How to detect the leakage of LED street lamp poles?
With a multimeter, cut to the voltage of the gear, and one end of the ground, one end is connected with the lamp (to the metal exposed part), and see there is no pointer or digital quantity to know the amount of data; to data leakage is.
What is the price of the LED street lamp from 30W to 60W? What are the advantages of the LED street lamp?
LED street lamp with the conventional high-pressure sodium street lamp is different, the light source of high power LED lamp with low voltage DC power supply, by the synthesis of GaN based blue LED and yellow fluorescent powder, white LED, with high efficiency, safety, energy saving, environmental protection, long life, fast response, high color rendering index unique advantages, can be widely used in city road lighting. The outer cover can be made of PC tube, high temperature resistance up to 135 degrees, low temperature resistance up to -45 degrees.
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.
How to calculate the number of Duodawa with LED lights
Road lighting requirements: mainly including illumination requirements, illumination uniformity requirements of two kinds.Uniformity is generally over 0.3, the greater the uniformity, indicating that the street lights, walking more open, lighting effect is better.Illumination is related to power and installation height of luminaire. For the street lamp, we hope that the greater the angle of light, the better evenness can be achieved, and that the distance between the lamp posts can be widened, the number of the lamp posts can be reduced, and the cost can be saved.
What is the reason for the low power factor of LED street lamp?
The LED street light power is generally more than 100W, if the power factor is low, it can only show that its driving power supply, there is no power factor correction, or is not done well.Well done, it should be more than 0.95.
The power supply of LED street lamp has no influence on the grounding power. The possibility that the power supply will burn out is not big enough
The ungrounded words are easy to produce static electricity is not good for the lamp and IC.
What is the luminous flux of LED30W solar street lamps?
High power LED street lamp has a long service life, and the light source life is over 50000 hours. It is 5~10 times of traditional lamp. The LED light source adopts the most advanced white 1W package, the surface bonding is welded on the 2mm thick aluminum based circuit board, and then the aluminum substrate is installed on the radiator plane to ensure the rapid heat transfer to the radiator. In addition the radiator and lamp shell integration design, fully guarantee the LED cooling requirements and service life. Advanced packaging technology to ensure high reliability of LED, good heat dissipation to ensure that LED work at the allowable temperature, the combination of the two, fully guarantee the long service life of LED.
