LED (light-emitting diode) street lamp energy-saving heat dissipation system

Abstract

The invention discloses an LED (light-emitting diode) street lamp energy-saving heat dissipation system. The main body is an LED street lamp, wherein the LED street lamp is formed by fixing a lamp cap to the top end of a lamp post; the lamp cap comprises a heat dissipation upper shell, a cooling pipe integrated board, a wind-driven stirring rod, an LED light source, a liquid lens and a transparent lower shell; the heat dissipation upper shell and the transparent lower shell are superposed together; the heat dissipation upper shell is provided with the wind-driven stirring rod; the top of a clearance between the heat dissipation upper shell and the transparent lower shell is provided with the cooling pipe integrated board; the lower surface of the cooling pipe integrated board is fixedly provided with the LED light source; the liquid lens is arranged below the LED light source; the liquid lens is corresponding to the transparent part of the transparent lower shell; and the cooling pipe integrated board communicates with the liquid lens, and is filled with a transparent coolant. The system is simple in structure; and the liquid cooling heat dissipation and the refraction effect of the transparent coolant are simultaneously utilized to further optimize the lighting efficiency, thereby enhancing the service efficiency of the LED street lamp and achieving the goals of energy saving and heat dissipation.

Description

technical field [0001] The invention relates to the field of LED lighting, in particular to an energy-saving and heat-dissipating system for LED street lamps. Background technique [0002] LED lighting, also known as light-emitting diode lighting, uses a solid semiconductor chip as a light-emitting material. In the semiconductor, the excess energy is released through the recombination of carriers to cause photon emission, which directly emits red, yellow, blue, green, blue, orange, and purple. , white light. [0003] With its inherent characteristics, such as power saving, long life, shock resistance, fast response, cold light source and other characteristics, LED is widely used in indicator lights, signal lights, display screens, landscape lighting and other fields, and can be seen everywhere in our daily life , Household appliances, telephones, dashboard lighting, automotive anti-fog lights, traffic lights, etc. However, due to the limitations of its poor brightness and ...
