Description

A kind of LED street light

technical field

The utility model belongs to the technical field of semiconductor lighting, in particular to an LED street lamp with excellent heat dissipation performance.

Background technique

At present, the street lamps used on the road are generally 150W-400W fluorescent lamps or sodium lamps. This kind of street lamp arrangement generally extends a bracket horizontally above the street lamp pole, and sets the street lamp at the end of the bracket; or directly on the lamp pole. The upper part curves above the road surface, and the street light shines down towards the road surface. The problems of this type of street lamp are that the area of the light source is small, the luminous efficiency is not high, and the power consumption is very large. In practical applications, for the sake of power saving, the brightness of street lamps needs to be adjusted at different time periods. In the middle of the night, it is often necessary to dim the street lamps to save electricity. It is very easy to damage the lamp tube when working in this state, and the service life of the lamp is short, so that the replacement frequency of the lamp tube is too high, and the maintenance cost is greatly increased. Street lights are usually erected at high altitudes, and frequent replacement brings a lot of inconvenience to the inspection, maintenance and troubleshooting of circuit pipelines, which not only increases the maintenance cost of the lighting system, but also increases energy consumption. When the power supply is in short supply, the lighting of street lights will be restricted.

Because LED street lamps have the characteristics of long life, high light source, no radiation, and low power consumption, LED semiconductor light sources have been widely used in the field of lighting in recent years. However, due to the unidirectional nature of LED lights, they are basically vertical to the ground at a certain angle Due to the characteristics of light guide, there are problems such as small illumination range and too concentrated light beam.
