Q:What is the grade of protection for Mega LED road lamp holder?

Protection level. First mark numbers indicate contact protection and foreign object protection level. Second mark numbers indicate waterproof protection grade. General: IP65, the highest level is IP68. Siu Chang street protection grade is IP65, can also be customized to do IP68.

Q:How many LED lights are there in the downtown area, W?

Depends on the width of the road, the normal is 250W metal halide lamp, there are 400W.. Used at intersections,

Q:Installation method of high-power LED street lamp

Before the welding temperature returns to normal, the LED must be prevented from any vibration or external force.

Q:How is the minimum illuminance of LED street lights Emin obtained? How to calculate?

Import the IES file of lamp into DIALux software, and then set up the height, elevation angle, installation interval and so on

Q:How to distinguish whether the LED lamps glare seriously, whether there is a standard?

Glare is not the light source, but the concept of light. At present, led-t8 fluorescent lamp has risen and is replacing PuThrough the fluorescent lamp market, because the lamps and lanterns are ready-made, cannot change, the led-t8 fluorescent lamp needs to the ordinary fluorescent lamp effectAs a result, the concept of glare is produced. Anti glare products need to take into account the brightness of the LED, the rows between the LEDCloth, spacing, led itself to the distance to the optical cover, shape of the optical cover, transmittance, etc., rather than simply outsideA problem of shell or arrangement.

Q:How much solar panels and batteries do 9W+10W solar light sources use for solar street lamps? LED

Solar street lamp uses solar energy, solar panels (to recharge the battery, the battery power supply to load at night, without complicated and expensive pipeline laying, adjustable lighting layout, safety and energy saving and no pollution, without manual operation is stable and reliable, saving electricity and maintenance free.

Q:Is there any difference between intelligent street lamp and intelligent LED street lamp?

The difference is that the light source of the latter has been defined as LED. The light source of the former is not defined and can be a variety of light sources.

Q:Does the LED street lamp need a starter?

LED light is not a starter, is a constant current source module, is 220V city power rectifier, with constant current circuit to each LED lamp power supply; LED lights can be connected in series, and then parallel. There is also not constant current, but in each series of branch current limiting resistors, to consider the range of voltage fluctuations, select the current resistance resistance value and power.

Q:Features of LED street lamps

LED street lamp is different from conventional, LED light source adopts low voltage DC power supply, by the high white GaN based blue LED and yellow synthesis, has the advantages of high efficiency, safety, energy saving, environmental protection, long life, fast response, high color rendering index unique advantages, can be widely used in the road. Cover can be made, high temperature up to 135 degrees, low temperature resistance up to -45 degrees. 1, the characteristics of its own - one-way light, without the proliferation of light, to ensure the efficiency of light.
