High quality LED solar street lamps have good lighting effects, excellent performance, stable operation, long service life. Solar street light is a coordination between components of the system. Therefore, the quality of the solar system components decide the quality of the solar street light

high quality led solar street lighting effect is good, excellent performance, stable operation, long service life. Solar street light is a need to coordinate between components of the system. As a result, the quality of the solar system components decide the quality of the solar street light. We should be to judge the quality of each component solar street lamps? Solar street lamps manufacturer Hu Jingli will take you to understand. Light-emitting diodes (leds) by light pole, solar modules, solar street lamps, solar battery controller and the light source ( Light) Composition. Quality evaluation standard of each composition is as follows: 1. The main light: high quality steel, thickness ( gt。 3. 0 mm) Inside and outside, high strength, hot dip galvanized, surface electrostatic spraying, good corrosion resistance; Color; Height can choose according to the design requirements and specifications. 2. Light emitting diode lamps and lanterns: cast aluminum materials, IP65 protection grade, can choose and match various shapes; 3. Illuminant: the light Angle above 110 degrees of high power, high brightness led light source, USES the constant pressure constant current drive circuit, with special heat treatment, stable performance, service life up to 10 years. 4. Solar energy battery components: conversion efficiency over 17% of crystalline silicon solar cell components, adopt high quality low iron tempered glass, yu xiang solar battery adopts flat glass, ultra low iron tempered glass, light transmittance over 90%. 5. Solar cells: select all 12 v lead-acid maintenance-free valve control type solar cell. They have a small internal resistance, large capacity and high charge and discharge performance. They can be in - 40 to 55 work environment safe use. 6. Controller: solar street lamps have patents optional multi-functional controller. Control time can be arbitrarily set. It has a meter, charging, overcharge, over discharge, short circuit, lightning protection and temperature compensation and so on the many kinds of protection function. This is a perfect intelligent control system. The above method of determining quality of solar street light components. We can also refer to the above points when choosing solar street light. At the same time, we should investigate the manufacturer of solar street lamps, select the regular manufacturers to purchase, to ensure the good quality of solar street light.
