High-efficiency heat radiation high-power LED street lamp holder

Abstract

The invention discloses a heat-dissipation LED stress lamp cap with high efficiency and large power, comprising an independent general lamp body consisting of a lamp body shell, an electric apparatus chamber cover, a light transmission shielding plate, an LED light source component, an optical management device, an LED driving control circuit, a lamp body upper cover, a head cover, an installation cover and a sealing ring; the lamp body shell, the lamp body upper cover and the light transmission shielding plate enclose a sealed chamber; the LED light source component is arranged in the chamber and is closely attached to the lower surface of the upper cover of the lamp body; the external side of the upper cover of the lamp body is provided with a plurality of heat dissipation ribs which are used for increasing the whole heat dissipation area of the lamp cap; the optical management device is arranged at the LED light source component; simultaneously, the lamp body shell and the electric apparatus chamber cover plate enclose another sealed chamber; the chamber body is internally provided with the LED driving control circuit. The LED street lamp cap has the advantages of scientific, reasonable and simple structure, easy production and manufacture, low cost, convenient installation and assembly, good heat dissipation effect, high luminescence efficiency and long service life.

Description

technical field [0001] The invention discloses a structural design method of a high-power LED street lamp lamp cap with efficient heat dissipation, and an LED street lamp lamp cap designed by the structural design method, belonging to semiconductor lighting [0002] technology field. Background technique [0003] Most of the traditional road lamps use high-power mercury lamps, metal halide lamps or high-pressure sodium lamps as light sources. High, lighting effects are unsatisfactory in terms of color rendering and anti-glare performance. At the same time, the development of semiconductor light-emitting diodes (LEDs) is extremely rapid. In recent years, the luminous efficiency of some LEDs has greatly exceeded that of incandescent lamps, and even exceeded that of fluorescent lamps. Compared with the traditional floodlight electric light source, the LED light source is basically non-toxic, non-electromagnetic pollution, and has many advantages such as small size, low energy...

Problems solved by technology

The mold cost is finally converted to the unit cost of the product. The high production cost greatly increases the business risk of the enterprise and the end user's ability to bear, which also restricts the development of new products to a large extent and hinders the technology of high-power LED lamps.
