LED road-light light-source

Abstract

This invention relates to a light source of LED street lamps including a heat-radiation device and a light emitting device, in which, said radiation device includes a radiation base and a heat conduction base board set on the base, said light emitting device includes LED lamps set on the conducting base board, a supply connecting to the LED lamps, lenses covering the lamps and fixing frames of the lenses, the design of the light emitting device and the heat radiation device is reasonable, and the devices can be compatible with the lamp shells of high pressure Na and high pressure Hg street-lamps.

Description

technical field [0001] The invention relates to a street light source, in particular to an LED street light source. Background technique [0002] Most of the existing street light sources use high-pressure sodium lamps, high-pressure mercury lamps, etc., which consume a lot of power, and the working voltage needs to be raised to more than 1,000 volts. A transformer must be installed on the street lights to boost the voltage. Minutes or even ten minutes, the utilization rate of the power grid is low, which is a heavy burden on the power grid and a great waste of power resources. In order to overcome the above problems, a kind of LED street lamp has appeared, which has the advantages of energy saving, environmental protection, long service life and no need for transformer to start. However, at present, the LED street lamps on the domestic and foreign markets all use the method of embedding LED lamps into the lamp housing to form an integrated lamp head, which is connected to ...

Problems solved by technology

However, at present, the LED street lamps on the domestic and foreign markets all use the method of embedding LED lamps into the lamp housing to form an integrated lamp head, which is connected to the street lamp pole through bolts or screw lamps. This structure makes the LED street lamp larger in size and easy to install It is in...
