LED lamp module with functions of three-dimensional convection, metal conduction and pollution prevention

Abstract

The invention discloses a high-performance LED lamp module with functions of three-dimensional convection, metal conduction and pollution prevention, and aims at improving the heat dispersion and the transparence and prolonging the service life of an LED lamp. The LED lamp module comprises heat radiating fins (1) with through holes, an air-vent (2) formed by parallel fins, an aluminium cavity (3) for placing the LED and a metal welded PCB, a metal welded PCB (4), an LED (5) and the like. The LED (5) and the metal welded PCB (4) are welded integrally in the aluminium cavity (3) after welded together, and the end face of the aluminium cavity is encapsulated by using toughened glass (13) and sealant to form an LED light source module. The heat radiating fins (1) are welded on the back of the aluminium cavity. The fins are at intervals of 5-15 mm to form a transverse ventilation air flue (14). The fin bodies are provided with a plurality of through holes to form a longitudinal ventilation air flue (15). Intervals of 5-30 mm respectively exist between the aluminium cavities and between the aluminium cavity and the lamp support. The fins are in parallel placed to form a vertical ventilation air flue (16). Thus, the transverse ventilation air flue, the longitudinal ventilation air flue and the vertical ventilation air flue are smooth, and temperature difference airflow convection and air natural convection formed by the heating of the LED are combined for efficiently radiating the heat.

Description

technical field [0001] The invention relates to an LED lamp module, in particular to an LED lamp module with three-dimensional convection, metal conduction and anti-pollution, which is widely used in high-power LED street lamps or tunnel lamps. Background technique [0002] With the development of the semiconductor industry, as the most promising new green light source in the 21st century, LED lighting has gradually penetrated into all walks of life. Compared with traditional light sources, LEDs have the advantages of long life, high efficiency, energy saving, and environmental protection, so LEDs are also called fourth-generation light sources. However, when the LED is working, about 80% of the input power is converted into heat energy. If this heat energy cannot be effectively dissipated, the junction temperature of the LED will rise, which will affect the parameters such as the luminous flux, color and dominant wavelength of the LED, making the LED The aging process is a...
