Solar light-emitting diode (LED) street lamp

Abstract

The invention discloses a solar light-emitting diode (LED) street lamp, comprising a solar assembly and a street lamp assembly, wherein the solar assembly is composed of a thin film solar cell, a storage cell and a controller and the street lamp is composed of an LED light source, a lamp cap shell, a lampshade, a street lamp controller and a lamp post; and the solar assembly is arranged at the top of the lamp post and the solar assembly is connected with the street lamp assembly. In the invention, the environment-friendly high-power LED light source is adopted, the luminous efficiency is higher, electricity is saved by more than 60% compared with the traditional sodium lamp and mercury lamp, better effect can be achieved with a numerical controller employed, and a dual power supply system which can utilize solar energy power supply and alternating current power supply is adopted, so that stable operation of street lamps is ensured. The solar LED street lamp has the advantages of energy conservation, environmental friendliness, long service life and the like.

Description

technical field [0001] The invention relates to the field of outdoor energy-saving lighting, in particular to an LED street lamp powered by solar energy. Background technique [0002] At present, high-pressure sodium lamps and low-pressure sodium lamps are commonly used in street lamps in most areas of my country. Although sodium lamps have the characteristics of high luminous efficiency and long life, their defects are also obvious. Take the high-pressure sodium lamp as an example: the luminous efficiency is generally 120lm / w, and the average lifespan can reach 24,000 hours, but the color temperature is too low and the color rendering index is too poor. In order to solve the problem of low color temperature of high-pressure sodium lamps and serious slant of light color, increasing the power is a common method, so that the power reaches 250-400W, and the problem of color cast of high-pressure sodium lamps is compensated for by a large amount of luminous flux. Increasing the...

Problems solved by technology

Increasing power will inevitably consume a lot of energy, so it is not suitable for today's general trend of energy saving and emission reduction

The LED light source has long life and low power consumption. Under the condition of suitable color temperature, although the lighting fixtures with LED as the light source display slightly lower illuminance, the light color is bright and the color rendering index is high.
