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:Technical requirements for LED street lamps

The average illuminance of illumination uniformity (uniformityof, road, surfaceilluminance) is 0.48, and the spot ratio is 1:2.5. accord with road illuminance. The actual 1/2 center spot reaches 25LUX, and the 1/4 center light intensity reaches 15LUX, the minimum light intensity is 4LUX at 16 meters, and the overlap light intensity is about 6LUX.6., it has a very good application prospect in the new city lighting. Dimming for depth, and colors and other features are not subject to dimming.7. meet the humidity: less than 95.

Q:How is the glare of a LED street lamp solved?

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, has the advantages of high efficiency, safety, energy saving, environmental protection, long life, fast response, high color rendering index unique advantages, can be widely used in the road. Cover can be made, high temperature up to 135 degrees, low temperature resistance up to -45 degrees.

Q:What qualifications does LED street lamp product need? Do you need 3C certification?

Our country government to honor WTO commitments, on December 3, 2001 announced a mandatory product certification system, from May 1, 2002 onwards, CNCA began to accept the first included in the mandatory product catalog 19 categories of 132 kinds of product certification application.It should be noted that the 3C logo is not a quality sign, but a most basic security certification.

Q:How is the rated current of the LED street lamp holder?

The rated power of the lamp cap is divided by the input voltage and then divided by the power factor.

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 is the maximum power of a LED street lamp at present?

If it is integrated, this power can be achieved.

Q:What heat sink is best for LED street lamp radiator?

What is the external force of heat, force, that is to say, with the use of external heat, fan in the lamps or using superconducting tube, water-cooled, and so on, the advantage of active heat dissipation, efficiency has been improved, but the structure is complicated, the cost is increased, and the service life of the cooling equipment is generally not too long, less than 2 years is basically finished.

Q:How much is the rated voltage of the LED street lamp? Is it direct current?

That is, the whole road lamp holder? It must be a constant current driving circuit! So it should be AC input, but the voltage is different.

Q:Does LED street lights save electricity?

The white LED: in 1998, light white LED is only 5 LM / W, in 1999 has reached 15 LM / W, this index is similar to general household incandescent lamps, and in 2000, light efficiency of white LED has reached 25 LM / W, the index and the tungsten halogen lamp is similar. In 2005, the light efficiency of LED was up to 50 lumens / watt. In 2010, the light efficiency of LED reached more than 100 lumens / watt. The working current of white light LED can reach ampere level. Thus, the development of white LED writers using lighting sources, will become possible reality.
