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

You can put appliances under the door, but you must not drive fixed down, otherwise the heavy rain water, may the water inside.

Q:LED technical requirement of street lamp 100W

LED light source technical requirements:(1) LED light source chip requires the use of internationally renowned brands (American CREE CREE, German OSRAM Osram and Holland PHILPS Philips), and uses low thermal resistance, good heat dissipation and low stress packaging technology.(2) using high luminous efficiency LED chip. LED chip luminous efficiency more than 110Lm/w, no ghosting, low light attenuation.(3) LED light source color temperature 4000K-6000K.(4) LED light source life: no less than 50000h.(5) the general color rendering index LED lamp: Ra = 75, the road evenness in more than 0.4.(6) LED street light 10000 hours less than 8%, the service life of 50 thousand hours, 50 thousand hours less than 30%.

Q:Road light is one of LED. How much is it?

500 to more than 1 thousand, there are different brands, different specifications, prices vary.

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:What ballast does the street lamp use?

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

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

The demands are different, the time is different. Of course, your technical decision time.

Q:What is the principle of constant current power supply in LED street lamps?

Inductors, coils, transformers, these inductors are switching power components, one of the main characters,The role is to assume load or pressure, isolation, filtering and so on.All other components, resistors, capacitors, and protective elements are used.

Q:The same brand of chips, how to judge the quality of LED lights?

Pay attention to the LED chips used in LED street lights. LED chip is the core part of LED street lamp, and the quality of LED chip affects the service life, brightness, light color of LED street lamp, etc.. The general import LED chip slightly better quality (such as Puri and CREE) as a municipal engineering, personal recommendations in addition to the two kinds of chips are not other, Liaoyuan century products outdoor Puri CREE, indoor use of wafer,

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

Q:30W LED solar street lamp 6 meters high, about how much?

Packing, excluding freight, tax, installation fee, approximately 1650-1750, too low, possibly of high quality, too high to be pit. This suggestion is supplied by brilliance lighting, solar street light brand manufacturers, for reference only.
