Q:Can you install LED street lights in your own yard?

But LED street lights need to be lowered after the use of electricity. It can also be powered by solar energy, without paying the electricity bill.

Q:What is the difference between the brightness and illuminance of LED street lights and the brightness and illumination of ordinary high-pressure sodium lamps?

There must be a difference... Normally。 A 100W LED street lamp, as long as done well, solve the problem of heat dissipation. The light distribution is good and can be equated to a 250W high pressure sodium lamp

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:Is the power LED lamp constantly flashing? Is it a power supply problem?

LED lamp and LED drive power does not match the normal single foot 1W beads under current: 280-300mA, voltage: 3.0-3.4V, if not enough power LED chip will cause light source stroboscopic phenomenon, it can not withstand the current high lamp of a bright, serious phenomenon of the light beads of gold or copper built-in burning off the lead light is not bright.

Q:Do constant current LED power supply for street lamp power supply? Is it better to use LED constant voltage power supply?

Relatively large changes, small changes can lead to constant voltage power supply current so constant current drive is better, before use Fuhua electronic outdoor power personal feeling can still hope to adopt, oh, welcome to ask.

Q:What is the design height and illuminance of LED street lamps?

1, the first screenshot of table 5.1.3, Weff means: effective width of the road.2, the above lamps refer to conventional lighting, the so-called regular lighting is the lamp installation height of 15 meters below the lamppost.3, light cut type refers to: the maximum light intensity direction of the lamp and the vertical axis of the lamp included angle between 0-65 degrees.4, half light type refers to: the maximum light intensity direction of the lamp and the vertical axis of the lamp included angle between 0-75 degrees.

Q:What's the price of the LED road lamp holder?

Generally speaking, as the working environment of street lamps is the worst, it is normal to go to eight or nine dollars per watt.

Q:What ballast does the street lamp use?

Inductance ballast, and generally use sodium lamp. The color of sodium lamp is yellow, not dazzling

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

60 watt LED lamp holder, about 6 meters light pole, 15-18 meters apart; 8 meters light pole is spaced at 20-24 meters, 12 meters, the lamp post is 32-36 meters apart. Data is for reference only.

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
