Q:What's the reason why the LED street lights don't work?

The LED lamp power is waterproof power, bad to change new power protection function is not perfect, directly affect the quality of fault phenomenon LED lamp 2, bad part there are several possibilities: 1), such as LED lighting power supply for multi-channel constant output, which may be a group of bad, 2) is LED chip is not good, or is the LED lamp cooling caused by bad burn LED chip.

Q:What's the reason for the flash of LED street lights?

Should be the power line station, power supply to a startup, behind the low voltage, so the lights flashing.

Q:Why do street lights use bat wings to match the light curve?

Make full use of light. LED light is diffuse type, not only will be the problem of uneven illumination glare.

Q:Is there a place where trees can hold LED solar street lamps?

The sun shines on the space of the photovoltaic panels

Q:What are the prospects for the development of intelligent LED street lamps?

Before 2015, LED Street will remain around 50% compound annual growth rate, by 2015, LED road lighting lamps in the field (mainly for street lights and tunnel lamp) the overall penetration rate reached 46%, the next two years will add more than 30 million LED street lights and tunnel lamp. These favorable expectations have brought greater potential for development of LED street lamps.

Q:How long does the general power LED power supply cycle last? Such as street lights, power supplies, 150W, 180W?

See what voltage input, what are the requirements?.If it is me, usually 40 days to get the prototype. 220V input, 56V, 3a out. Without special requests.

Q:What is the actual service life of the LED street lamp?

In good heat dissipation, rated current work, with constant flow drive, high quality LED life up to 50 thousand small season

Q:What are the after-sales service of solar LED street lamps?

Check whether the current is good waterproof and lightning protection measures, whether the goods meet the delivery samples, construction lights, and related lamps and materials standards, to prevent the injection of defective products, reduce labor, and strive for a qualified acceptance. These are personal opinions, and the work may still need to be done. I am here for the time being, and leave it to other friends

Q:Why is the higher the current, the lower the light efficiency?

What I know is: junction thermal resistance, spectral distribution drift

Q:What is the LED Street pressure balancing respirator?

LED lamp pressure balancing apparatus is also called micro PU waterproof breathable valve at home, LED street is a wide application of pressure balance apparatus, such as: LED outdoor lighting, communication equipment, solar photovoltaic, auto controller etc..The role of the LED Street pressure balancing respirator is as follows:1, waterproof, dustproof, anti pollution, protection level IP65~IP68.2, chemical resistance, high and low temperature, anti-aging and so on, improve the harsh environment of the product reliability.3, prevent condensation, fog, and improve product life.4 、 micro heat dissipation and balance pressure difference. Improve product integrity.
