Q:How high should the installation height of the LED street lamp be?

In order to avoid glare, you can choose the f (d) (E), the installation height of street lights should not be less than 4.5m. The distance between the poles of the street lamp can be 25 to 30m, and the distance between the lamp posts entering the curve should be reduced appropriately.

Q:Which is better, the LED street lamp and the traditional street lamp?

For street lighting and tunnel lighting projects, the sodium lamp itself has a large power, greater starting current, and thicker cables. Led because the power is small, the cable needs small, the overall cost of the project, consider the cable, then can be about 20% cheaper. The power can be saved by about 30%, and the service life is increased by 50%.

Q:Can you tell me how to solve the problem of LED street lamp heat dissipation? Ask for an introduction

The biggest problem that hinders the popularity of LED lighting applications is the high price and high price of LED lights, which is due to the heat problem. And because of the heat problem, the current LED street lamp is developing on the edge of death. Shenzhen City Xin too light technology company to solve the problem of LED street lamp temperature rise from the source. This technique is based on current control completed. Main components: AC-DC power supply, LED intelligent driving module, feedback current driving part of the wick wick controlled module in intelligent LED, therefore, will not affect the AC-DC power supply. AC-DC power does not produce too much heat, as long as the design and production can provide stable current can be 24V/2A or 36V/3A. The construction is convenient: power supply and LED intelligent module can be installed in the lamp at the bottom of the wick is made can be directly installed on the common street. No loss, guarantee a year. Because the power and illumination invariant intelligent module installation at the bottom end of the lamp post, the lamp does not need waterproof. Can also use LED LED street lamp intelligent driving module: do not need to have the radiator shell power supply AC-DC:100 yuan, LED intelligent drive module: 300 Wick yuan (source module): 120 1W LED chip, every 1 yuan, or 120 yuan, coupled with the substrate, the processing fee is 200 yuan in profits, while the total 320 yuan.

Q:How to judge the light type of LED street lamp?

It will be tested by a large distributed photometric tester,

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:Who knows the relationship between the number and weight of LED street lamp

The relationship between the number of LED light weight and beads, the strength of your life,Can not get a formula, a single lamp can be 1W, or 100WThe relation between street light weight and street lamp power can still be obtained, only at presentDie casting space aluminum cooling, about 100W, about 20 pounds

Q:Why does a LED street lighting system come with a phase light?

Because the LED light current is in the Ma level and slightly leaks, the current will shine.

Q:Why solar energy centralized power supply street lamp must be supplied by AC LED lamp?

1: DC transmission distance is limited, the pressure drop is very high2: DC voltage - protection switch, controller parts and other technologies immature or cost slightly higher3: DC wiring voltage is not very high, but the street lamp power is not small, the current will be very high, the cable cost

Q:How long does the general power LED power supply cycle last? Such as street lights, power supplies, 150W, 180W?

The demands are different, the time is different. Of course, your technical decision time.

Q:Does LED street lights save electricity?

The white LED: in 1998, light white LED is only 5 LM / W, in 1999 has reached 15 LM / W, this index is similar to general household incandescent lamps, and in 2000, light efficiency of white LED has reached 25 LM / W, the index and the tungsten halogen lamp is similar. In 2005, the light efficiency of LED was up to 50 lumens / watt. In 2010, the light efficiency of LED reached more than 100 lumens / watt. The working current of white light LED can reach ampere level. Thus, the development of white LED writers using lighting sources, will become possible reality.
