Q:What is the role of heat phase change material on a LED street light?

Mainly to play the role of heat dissipation! I don't agree with that upstairs. The heat dissipation of LED street lamp can be solved by some auxiliary things. For example, a small fan with a stronger coefficient of heat is used as a shell...... And so on, these can solve the problem of heat dissipation!

Q:How big is the power of a LED street lamp?

General 20W-300W have

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

LED well, because it's energy efficient and bad, it doesn't affect anything else

Q:How much is the LED street lamp with six meter pole?

It depends on the price of the lamp and the height of the lamp postDomestic LED street lamps, the general price can be 7-8 yuan per watt. 100W street lights, for example, cost about 800 dollars. Of course, this is to buy an end customer, and if you are an agent, the price will definitely be cheaper.

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

If you want to measure the value, I can only say that the approximate, because the illuminance value on a point value, the actual measurement is the target area is divided into small areas of uniform, center to measure each region with the value of the measured value, there is a minimum value.

Q:22 km road, every 33 meters to install a street lamp, street light power 120W, attached to the LED display 60W, a total of 180W, seeking the best laying line program

If there are 10 or so parallel units. Each unit of parallel =0.18x60=10.8KW, 16mm - 25mm - copper or aluminum wire. Light controlled single-phase AC contactor 100A.

Q:LED street light dedicated drive power 98W14 string 7, and ask 14 string 7, and what does that mean?

The 14 LED are connected in series to calculate a set, and then there are seven groups, which connect the seven sets of positive and negative electrodes to the negative pole, i.e., the seven groups are connected in parallel, and this is the meaning of "14 strings of 7".

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:Constraints on LED street lights

Maintenance problem. High pressure sodium lamp is good for maintenance. As long as the lamp is scrubbed, it is not necessary to replace it. The light source is changed once every 4 years, which is very convenient. And LED street lamps, involving LED tubes, modules (including lenses, etc.), power devices, etc., components and components of the possibility of greater damage, maintenance difficulties, it is possible to replace the whole, higher costs. High price: LED street price is 2-5 times that of high pressure sodium lamp, even if the power consumption of LED lamp is only 1/2 HPS, but because the price is much higher than that of high pressure sodium lamp, high pressure sodium lamp is replaced by LED cost recovery cycle will still be very long;

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
