Q:In the solar street lighting system, who is the LED driver connected to? How to choose the LED driver power?

It is based on a few strings and a few beads to choose, of course will also consider the power, are generally mounted to the lamp holder, but now generally used one of the cross flow controller

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: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:The 6 meter high watt LED bulb lamp should match

Solar street lighting controller is divided into two buck and step-up, Buck 50 yuan, step-up 80 yuan, the warranty for three years. Now the conventional 6 meter 30W power solar energy set price is about 1260 yuan, the detailed price ha needs to calculate according to the lighting time and the rainy days.

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 are the main differences between a LED street lamp and a solar street lamp? What are the advantages and disadvantages of each?

LED street lamp, that is, semiconductor lighting, is a solid cold light source. It has the characteristics of environmental protection, pollution-free, less power consumption, high light efficiency, long life and so on. Therefore, LED street lamp is the best choice for road lighting energy-saving transformation.

Q:Is it possible to use 100W LED power for street lamp power supply?

Power problems, the general power supply, you can also use 1 years, a little better 2 years.

Q:LED good or low frequency electrodeless lamp?

LED is the light produced by hole migration. Electrodeless lamp is an electromagnetic field to excite gas particles. Judging from the current technology, LED is not mature, so electrodeless lamp is better

Q:What is the distance between the usual street lights?

There is no standard, and some are required to achieve the value of illumination, there is no hard and fast requirements, generally speaking, the distance between the street lamp and the lamp height and the number of watts.

Q:How to calculate the radiation area of solar LED street lamp

According to the light distribution, the installation height and elevation of the lamp, it can be calculated by trigonometric function
