Irradiation angle-adjustable high-cooling property high-power LED road lamp cap

Abstract

A high thermal diffusivity high-power LED street lamp cap with adjustable irradiation angles belongs to the technical field of semiconductor lighting. The LED street lamp cap comprises a lamp cap upper cover, a lamp cap lower cover, a supporting skeleton, a running rest, a lamp cap end closure, a radiator, a light manager, a light penetration panel, a plurality of LED light source drives, a plurality of LED light sources, and an LED breadboard. The lamp cap end closure is fixed on one end of the radiator. The light penetration panel is sealed on the uncovered part of the radiator by glue. The lamp cap upper cover and the lamp cap lower cover are folded, connected and fixed on the other end of the radiator. The radiator is hung on the base plane of the supporting skeleton which is fixed on the running rest. The LED light sources are arranged and encapsulated on the LED circuit board at regular intervals. The LED circuit board is arranged in a sealing space formed by the light lamp end closure, the radiator, the light penetration panel, the light cap upper cover and the like. The back of the LED circuit board is tightly attached to the inner wall of the radiator by a heat-conducting medium. The street lamp cap has good heat dissipation effect, adjustable illumination angle, good service performance and long service life.

Description

Technical field [0001] The invention discloses a structure of a high heat dissipation high power LED street lamp lamp cap with adjustable illumination angle, which belongs to the technical field of semiconductor lighting. Background technique [0002] At present, the light sources used for street lighting include: incandescent lamps, high-pressure mercury lamps, high-pressure sodium lamps, metal halide lamps, fluorescent lamps, etc. The main disadvantages of these lamps are: ①Not environmentally friendly: they contain heavy metals such as mercury, lead, and arsenic, which are harmful to the environment. Harmful; ② high energy consumption; ③ short life. [0003] Traditional street light sources contain heavy metals and pollute the environment; LED light sources do not contain heavy metals and will not pollute the environment. Because the traditional street light source is a spherical light source, the light divergence is not easy to control, and the light easily overflows the desi...

Problems solved by technology

[0002] At present, the light sources used for street lighting include: incandescent lamps, high-pressure mercury lamps, high-pressure sodium lamps, metal halide lamps, fluorescent lamps, etc. The main disadvantages of these lamps are: ① Not environmentally friendly: they contain heavy metals such as mercury, lead, and arsenic, which are harmful to the environment. Harmful; ② high energy consumption; ③ short life

[0008] At present, there are many kinds of LED street lamps at home and abroad, and their performance is uneven. Due to the constraints of LED lamps in terms of quality and heat dissipation requirements, it is difficult to meet the lighting needs of ultra-high-power LED street lamps.
