Q:Is the price of the street lamp factory in led the same?

The price of street lamps at the LED street lamp factory is the same as that of the foreign ones. LED street lamp external price = cost + profit. The cost is fixed, that is, profits will change, in addition to street lamps manufacturers require profits, the salesman will be appropriate adjustments, this depends on the salesman personally

Q:Technical requirements for LED street lamps

The technology is mature day by day, and the efficiency of light source has reached over 100lm/W, which makes it possible to save energy in urban street lighting. LED street lamps, especially large power LED street lamps, are attacking the traditional street lamp market at a tremendous speed.High power LED street lamp, as its name suggests, is power greater than 30 watts, using a new type of LED semiconductor light street lamps. The standard is generally the illuminance uniformity of the road surface, which conforms to the illumination of the road. The actual 1/2 center spot reaches 25LUX, and the 1/4 center light intensity reaches 15LUX, the minimum light intensity is 4LUX at 16 meters, and the overlap light intensity is about 6LUX. Refers to the use of solar panels for the supply of power LED street lamps. The conversion rate of 1. light is 17%, the solar energy per square meter is 1000W, and the actual utilization efficiency is 170W

Q:What's in the lamppost of the LED street light? What is the function?

LED street lamp poles are: cross flow source, the role of the current stability, so that the light effect to achieve a stable effect, as well as variable pressure.

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

Minimum illumination Emin, if you go to calculate or use lighting software (DIALux) simulation, you can get the minimum illumination Emin, how to simulate this? This is not clear

Q:What are the 6 main disadvantages of LED street lights? What are the 6 major disadvantages?

Light LEDAfter a period of illumination, the light intensity of LED will be lower than that of the original light

Q:What is the reason that the range of the LED100W street lamp is not enough or the brightness is not enough?

The cover available PC pipe production, a high temperature of 135 degrees. In the LED street lamp design, PC cover plays a big role in decision radian illumination area, determines the height of light intensity, light material purity decided loss estimate you are one of the causes, and also cause the supply voltage to be checked, know how to lead the way 1, an antidote against the disease, the characteristic of LED lamp - light, no light diffusion, ensure light efficiency;

Q:What ballast does the street lamp use?

Using metal halide ballast, it depends on what kind of light, are now "popular" LED lighting, however, there are two main types of our common street lighting, is a metal halide lamp, the other is a metal halide lamp, the latter is a little better, but the price is more durable some high.

Q:How much is the LED terminal voltage of the solar street light controller v?

This voltage is often the voltage of the LED designer, not every vendor is the same, you can directly use the meter to measureHowever, I have contacted 2 companies of solar street light controller, output voltage is 12V, can be verified

Q:Do you know the assembly process of the LED street lamp?

The lead out line of the lamp cap is welded with the input end of the power supply, and the two power lead wires of the palm and the white are welded at the output end of the power supply.

Q:Street lights and signal circuit connections

LED street light color light than many high-pressure sodium lamp, high-pressure sodium lamp color index is only 23 enterprise directory, while the LED lamp more than 75 of the color index, take into account the psychological point seems to be visually reachedThe same brightness, lighting LED lamp, can be reduced by an average of 20% or more, than high pressure sodium (refer to inluReasonable lighting standard); page 5, LED street light a small decline, a year decline was less than 3%. 10 years still reached the road soHotel and illuminance requirements, while the high pressure sodium lamp big drop, about a year has dropped by more than 30%, so, LEDStreet use power can be lower than that of high-pressure sodium lamp designs; page 6, LED streetlights energy-saving automatic control devices can be achieved in time to meet the situationLighting conditions, as far as possible to reduce the requirement of different maximum power saving energy; Guangyuan Wang Technology Co.
