FAQ

What role does the light controller and driver play in the LED street light component?

Constant current drive chip solves the problem of uncontrollable current before constant voltage drive. At present, the constant current chip can achieve constant current accuracy of about 1%, and has a simple peripheral control interface, which can flexibly set the required output current, so it is very popular. But these chips are much more expensive than constant chips, and peripheral circuits are complex. At the same time, because of the constant output current, the whole chip will discharge faster when the battery is used as power supply.

What's in the lamppost of the LED street light? What is the function?

Light emitting diodes (LightEmittingDiode, abbreviated as LED) is a semiconductor pn junction formed with weak electricity can light high efficiency solid-state light source based on the forward bias voltage and the injected current, injected into the P region of the hole and injected into the N region electron in diffusion into the active region after radiation and emit a photon, electric can be directly converted into light energy.

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

LED street lights are different from high pressure sodium lamps (both street lamps), as well as superior power consumption

At present, the most mature street light source, relative to the LED lamp, is not high enough for the use of the environment

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

Solar street lights rely on the top solar panels to install light energy, as long as the tree can not block the top of the solar panel, to ensure that it is full of exposure to the sun, does not affect the work.

LED lamp with air leakage to help the thunder?

There is no air leakage with LED lights for the role of lightning protection. The function of the switch of leakage air breaker is to work by current. To enable the street circuit with lightning protection function, must use a surge protector, installation and circuit breaker in parallel. It works by limiting the overvoltage and cutting off the circuit as long as the voltage exceeds the set point to protect the electrical equipment.

Why solar energy centralized power supply street lamp must be supplied by AC LED lamp?

1: DC transmission distance is limited, the pressure drop is very high2: DC voltage - protection switch, controller parts and other technologies immature or cost slightly higher3: DC wiring voltage is not very high, but the street lamp power is not small, the current will be very high, the cable cost

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.
