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

See lane, general trunk road will be installed in 150W high power LED, most of the others are 100~120 watts (also 80), the other way is generally 60W

Q:How to determine the power of LED street light?

Because this situation does not see the chip surface, so it can only be estimated(attention: eundong Street)Supplement:LED street lamp power LED street lamp power and rural branch city road has no clear standard, but in general: LED lamp power city road about 80W-250W LED Street Village Branch power about 30W120W.

Q:What are the standards for LED street lights?

1, in order to implement the "industrial enterprise overall quality control measures" issued by the State Economic Commission, and comprehensively improve the design, construction and operation level of street lamps, this standard is formulated.2, the requirements of this standard, street lighting design, maintenance, installation, operation and other work should comply with the implementation.3, this standard from the date of the trial, in the implementation should continue to sum up experience, and in accordance with the needs of the development of safety production, modify and supplement, make it gradually perfect.

Q:How much is the power supply voltage of street lamp LED?

220V AC through the LED power, converted to DC 35V voltage supply to the chip, LED chip can only withstand DC 35V voltage!

Q:Compared with LED street lights, what are the advantages of graphene street lamps?

And if compared to ordinary sodium lamp, but also can save energy 70%. Thus, on the basis of the same amount of electricity, graphene street lighting will be higher, and this benefit can also benefit drivers traveling on the road. Almost all of the common LED lamp has a "black light", but the street surrounding light, but dark; and graphene Street due to changes in brightness and light, can avoid this effect of road crossing chiaroscuro "".

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:LED street lights generally use how many W, how much density is more appropriate?

100W or so, the distance is about the same as ordinary street lights!

Q:What is the voltage of the street lamp? What about LED?

Street light voltage is generally 220V AC

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:LED lamp of common sense, several, such as the LED street lamp, there are many W have many stars, some lamp is a lamp there are a lot of W number

Are you saying that a lamp with LED lamp or with a large number of W! This is not to say the street is not very high if you don't need very bright I think might use 1W 3W this kind of W is relatively smaller number of beads will power many dozens of W a integrated product although the flux is large but his heat is very large if you can not solve it scattered don't consider those.... But if your technology is mature and fairly good, you can use it to integrate power
