Q:What's the advantage of Led street lights?

LED street lamp is different from conventional, LED light source adopts low voltage DC power supply, by the high white GaN based blue LED and yellow synthesis, can be widely used in road, the outer cover can be made of high temperature resistant up to 135 degrees, low temperature reached -45 degrees.

Q:Solar LED street lamp, how much is a set of solar street lamps wholesale price?

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:For the LED street light distribution, is it better to use a lens or a reflector?

Lens better point: the lens can be arbitrarily better match light, mold work is better than using reflective glass, the price of natural cheap

Q:Can the power supply for the LED street lamp be placed under the lamppost?

In fact, it is more convenient to put the driver into the electric door directly. If the later stage needs maintenance, it is not necessary to remove the whole lamp.

Q:How to detect the leakage of LED street lamp poles?

With a multimeter, cut to the voltage of the gear, and one end of the ground, one end is connected with the lamp (to the metal exposed part), and see there is no pointer or digital quantity to know the amount of data; to data leakage is.

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

There are a lot of a lamp of general LED lamp, according to a count of each tileIf the LED street lamp is a block of chip, it can be installed according to the height and brightness of the street lamp, and then it can be estimated that each block is 30W/50/100W

Q:Where can I buy LED street lamp and aluminum alloy shell, what's the quality of the product? Who can provide?

Shortcoming:1, LED packaging process is complex2, multi core integrated heat radiating shell is too concentrated, need efficient, otherwise LED decay seriously affect its service life.3, light concentration, LED low luminous efficiency, is currently around 85LM/W4, the use of multi-core string combined with the circuit, compared to a single core package, there is a high probability of reliability problems

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

Because the ground has been connected.

Q:How big wires should fifteen LED street lights require?

What's the power of a street lamp?!

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
