A cylindrical integrated LED (light emitting diode) light source of street lamp

Abstract

The invention relates to the technical field of illumination light sources, and in particular relates to a new LED (light emitting diode) light source of a street lamp, namely, a cylindrical integrated LED light source of a street lamp. The LED light source of a street lamp consists of a screw base, a plastic lamp holder with an air inlet, a cylindrical PCB (printed circuit board) substrate, LEDs, an LED driving power supply and a radiating fan which are connected; and the LED light source of a street lamp is characterized in that: the screw base is connected with the plastic lamp holder; the plastic lamp holder is connected with the cylindrical PCB substrate; the LEDs are uniformly welded on the outer surface of the cylindrical PCB substrate; and the driving power supply and the radiating fan are fixed in a cylindrical cavity of the cylindrical PCB substrate through a fixing bracket. The cylindrical integrated LED light source of a street lamp provided by the invention has a compact structure and strong generality, and is convenient to replace and to be compatible with the street lamp with traditional light source.

Description

technical field [0001] The invention relates to the technical field of lighting sources, in particular to a new LED light source, which is a cylindrical integrated LED street light source. Background technique [0002] LED light source is a new product of lighting source. Due to its advantages of long life, high light efficiency, energy saving and environmental protection, it has become the development trend of a new generation of light source, and has been widely used in the field of street lighting. [0003] Now, the vast majority of LED street lamps adopt a structure in which several LED light-emitting diodes are placed on a flat plate with a reflector to form a plane light source. The shape is almost a rectangular or square flat structure, and the style is rigid, which is different from the street lamp itself.

AI Technical Summary

Problems solved by technology

[0003] Now, the vast majority of LED street lamps adopt a structure in which several LED light-emitting diodes are placed on a flat plate with a reflector to form a plane light source. The shape is almost a rectangular or square flat structure, and the style is rigid, which is different from the street lamp itself. The requirements as a landscape element do not meet; and the current LED street lamps are all bulbs and lamp holders in one structure, once damaged, it is difficult to replace, and this type of light source cannot be used like traditional high-pressure sodium lamps, metal halide lamps and other cylindrical light sources. Traditional street lamps are compatible and have poor interchangeability

Although some manufacturers have produced cylindrical LED street light sources, most of them are split structures in which the light source and driving power are placed separately, and there are still disadvantages such as inconvenient installation and difficult maintenance.
