Multi-light source LED road lamp

Abstract

The invention provides a high-power LED street light which can be simultaneously provided with one or two LED light source modules, being composed of a heat transfer and dissipation system, a luminescence and light distribution system, a power source transformation system and a lamp shell, wherein, the heat transfer and dissipation system consists of a heat conducting substrate of the LED light source module, a heat conducting adhesive and a radiator integrated with an upper shell; the luminescence and light distribution system consists of the luminous surface of the LED light source module, a sealing ring, a reflecting shade, a light distribution lens and a transparent lampshade; the power source transformation system consists of a power source incoming line, a rectification drive controller, a power source outgoing line as well as the positive and negative terminals of the LED light source module. The structure of the invention can effectively enhance the luminous intensity of a single lamp, simultaneously, the radiating structure of the lamp is more beneficial to heat dissipation, which causes an LED chip to work under the appropriate temperature environment, thus achieving the aims of prolonging the service life of the lamp and reducing the photodegradation of the lamp.

Description

technical field [0001] The invention relates to an LED lamp, in particular to a multi-light source LED street lamp. Background technique [0002] As an effective energy-saving product, LED light sources are more and more used in municipal lighting systems. LED street lamps also have the tendency to replace traditional street lamps. However, the current integrated package LED light-emitting chips have limited power. Increase the illuminance by increasing the number of lamps and reducing the lamp distance, which not only increases the investment but also affects the aesthetics. At the same time, high-power LED street lights, especially high-power LED street lights above 100 watts, have affected the service life of the lamps due to heat dissipation problems, thereby restricting the development of the industry. Contents of the invention [0003] In order to overcome the above-mentioned defects, the present invention provides a multi-light source LED street lamp, which can eff...
