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:Do you think it is expensive to install LED street lamp with WIFI function?
The cost will be much higher, and it will involve control and network problems.
Q:How many watts is the LED street light 30W-900M?
30W is the W number of street lights. 900M, is the current power supply, 30W lamp 900 Ma, more heart lighting to help you
Q:Excuse me, LED experts. How many watts do LED street lights usually have on the roads?
Choose different power or combinations according to the width of the road, the density of the street lights and the required illuminance
Q:LED street lamps must be constant flow source? No constant current source, can I?
Now generally constant current power supply, if not the constant current power supply has a great damage to the lamp
Q: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.
Q:Features of LED street lamps
2, LED street lamp has a unique two optical design, the LED street light exposure to the required lighting area, further improve the lighting efficiency, in order to achieve energy-saving purposes.3, LED has reached 110-130lm/W, and there is still great room for development, the theoretical value of 360lm/W. The luminous efficiency of high pressure sodium lamp is only increased with the increase of the power, therefore, the overall optical efficiency of LED lamp is better than high voltage sodium lamp; (the overall efficiency of light is theoretical, light effect actually more than 250W higher than that of LED high pressure sodium lamp).4, LED street light color is much higher than that of high pressure sodium lamp, high pressure sodium lamp color index is only about 23, while the LED lamp color index reached more than 75, from the point of view of visual psychology, achieve the same brightness, illumination LED lamp can average 20% lower than high pressure sodium lamp,.5, a small decline, a year decline of less than 3%, 10 years still reached the requirement of road, and high pressure sodium lamp failure, a year has decreased by more than 30%, therefore, LED lamps used in the design of power can be lower than high pressure sodium lamp.
Q:What is the role of heat phase change material on a LED street light?
To help its heat dissipation, stabilize its effectiveness, and play its energy-saving features, the most important thing is to extend its service life, as we all know, LED street lamp technology is the biggest difficulty is the problem of heat dissipation.
Q:What ballast does the street lamp use?
You should first look at what is the light source, there are high pressure sodium lamp, low voltage lamp, high-pressure mercury lamp, metal halide lamp, ceramic metal halide lamp, LED lamp and energy-saving lamp, fluorescent lamp, electrodeless lamp and so on, to see what, some others do not need to ballast, general use now most of the high intensity discharge lamp, it is need to use high pressure sodium lamp, ballast or electronic ballast
Q:The cold white light LED lamp beads or warm white beads?
The light emitted by neutral white LED has more yellow and red wavelengths, and this spectral distribution helps to distinguish between different liquid surfaces on the tarmac.
