LED (Light Emitting Diode) module

Abstract

The invention discloses an LED (Light Emitting Diode) module. The LED module comprises a lens group, LED beads, a circuit board and a radiator, wherein the LED beads are arranged on the circuit board in a welding way, the circuit board and the radiator are fixedly connected, the lens group is arranged above the LED beads in a covering way and is connected with the radiator, a wire penetrating hole is formed in the radiator, and a wire which is connected with a power supply penetrates through the wire penetrating hole and is arranged on the circuit board in the welding way so as to supply electricity to the LED beads; following double sealing structures of a double-layer silicone ring sealing structure and a wire double-layer sealing structure are adopted by the LED module. According to the LED module disclosed by the invention, a double protection mode of the double-layer silicone ring sealing structure and the wire double-layer sealing structure is adopted, the protection level of the LED module is effectively increased, the sealing performance of the LED module can be better, and water leakage is not easily caused; in addition, the structure of the lens group is redesigned, the surface of the lens group is additionally provided with reinforcing ribs, and the defect that the middle part of the lens group easily protrudes and deforms after the lens group is used for a long time is effectively solved; narrowing design is also carried out on the lens group, the raw materials are saved, and the cost is reduced.

Description

technical field [0001] The invention relates to the lighting field, in particular to an LED module. Background technique [0002] LED lamps have the advantages of energy saving, long life, good applicability, short response time, environmental protection, gorgeous colors, and pure luminous colors. They are the development direction of the lamp industry. [0003] Street lamps are an important part of urban lighting. Traditional street lamps often use high-pressure sodium lamps. High-pressure sodium lamps emit 360 degrees of light. The disadvantage of large light loss has caused a huge waste of energy. At present, the global environment is deteriorating day by day, and all countries are developing clean energy. With the rapid growth of the national economy, the contradiction between energy supply and demand in my country has become increasingly prominent, and there has been a serious shortage of power supply. Energy conservation is an urgent problem to be solved at present. T...

Problems solved by technology

[0005] 1. The waterproof structure has defects: the existing LED module is sealed by the waterproof ring and the wire cover, and the protective layer of the LED module is single. If there is water seepage in one of the waterproof ring or the wire cover, the protective layer of the LED module is broken. It is very easy to cause water seepage and damage the LED module;

[0006] 2. The structure design of the lens group of the existing LED module is not reasonable enough, and there will be a convex phenomenon in the middle after long-term use, which will affect the luminous performance and appearance of the LED module;

[0007] 3. The arrangement of the lenses of the existing LED module and the arrangement of the lamp beads on the circuit board are not optimized, resulting in a wider width of the lens group and circuit board, which makes the cost of raw materials higher
