Q:LED street is a single bead or multiball well

Well, if you say so, I think it's a good choice from the street light to the light! I feel more than the heat of power consumption is relatively large ~ ~ ~ relative heat burden of large transformer single bead will point this is just I feel ~ ~

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

Solar street lighting controller is divided into two buck and step-up, Buck 50 yuan, step-up 80 yuan, the warranty for three years. Yangzhou is the largest production base of street lamps in China, which can be visited by manufacturers.

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

Fault phenomenon 1, all LED does not light 1), if the reason is: city power protection switch trip, hit it, and if the power is not bright, generally LED drive power failure,

Q:What are the standards for LED street lights?

1, in order to implement the "industrial enterprise overall quality control measures" issued by the State Economic Commission, and comprehensively improve the design, construction and operation level of street lamps, this standard is formulated.2, the requirements of this standard, street lighting design, maintenance, installation, operation and other work should comply with the implementation.3, this standard from the date of the trial, in the implementation should continue to sum up experience, and in accordance with the needs of the development of safety production, modify and supplement, make it gradually perfect.

Q:How much is the price of the LED street lamp?

Tens to hundreds of dollars range, this depends on what you focus on the LED street lights? Guoqiang photoelectric cost-effective lamps

Q:What is the active power of LED street lamp? What is the relationship between input voltage and current and power?

When the alternating current through the load resistor, and the resistance of the AC voltage and AC current through the resistor is the same phase, and between them the phase angle phi = 0 degrees, while the active power consumption in the resistive load, power grid to supply energy. When the alternating current through the pure inductance load, phase AC voltage on the advanced phase of current 90 degrees and the angle between them phi = 90 DEG, produce reactive power in inductive load, power supply of electric energy in the inductor for temporary storage and magnetic energy back to the grid into electricity such a periodic cycle, results for grid is not energy, so that the "reactive power", but "reactive power" and "reactive current" still exist. When alternating current through pure capacitance load, also similar to this, but the phase AC voltage on the lag phase of current 90 degrees and the angle between them phi = - 90 degrees.

Q:How can I get the LED street light?

Products must be certified in order to export, and if you do not have the right to export, you have to rely on agents, export companies might as well do domestic, I can also do certification agent

Q:What are the parts of a LED street lamp?
