Waterproof and moistureproof structure of LED underground lamp and installation method

Abstract

The invention discloses a waterproof and moistureproof structure of an LED underground lamp, which includes an LED underground lamp body with a radiator in a pit and a plastic pre-embedded part. Tempered glass is arranged on one face, facing upwards, of the LED underground lamp, a boss is arranged on the bottom surface of the radiator of the LED underground lamp, the boss is provided with a through-hole communicating with an internal cavity of the radiator of the LED underground lamp, the boss is provided with an aluminum alloy waterproof breather valve for maintaining the air pressure balance in the cavity of the LED underground lamp, a silicone hose sleeves the lower end of the boss, and the silicone hose communicates with a silicone telescopic air bag through a direct connection air pipe connecting head. According to the structure, the air pressure balance in the cavity of the LED underground lamp is maintained, meanwhile, the aluminum alloy waterproof breather valve is prevented from being damaged to fail to work when the LED underground lamp is immersed in water, and thus the long-term waterproof and moistureproof effects are achieved. The invention further discloses an installation method of the waterproof and moistureproof structure of the LED underground lamp. The method can ensure that the waterproof and moistureproof properties of the LED underground lamp in the severe environment cannot fail.

Description

technical field [0001] The invention relates to a waterproof and moisture-proof technology for lighting fixtures, in particular to a waterproof and moisture-proof structure and an installation method of an LED buried lamp. Background technique [0002] LED buried lights are widely used in landscape lighting occasions, especially various squares, roads, bridges, sidewalks, and park lawns are inseparable from LED buried lights. A complete LED underground light usually includes a lamp body and plastic embedded parts. The lamp body is composed of tempered glass, sealing rubber ring, heat dissipation shell, and light source components. The light source components include lamp panels, waterproof terminals and related multi-strand rubber sleeves. line, but the structure of this LED buried light is not waterproof and moisture-proof, because when the buried light is working, the LED generates high heat, which makes the gas in the cavity of the buried light gradually expand, and the a...

A complete LED underground light usually includes a lamp body and plastic embedded parts. The lamp body is composed of tempered glass, sealing rubber ring, heat dissipation shell, and light source components. The light source components include lamp panels, waterproof terminals and related multi-strand rubber sleeves. line, but the structure of this LED buried light is not waterproof and moisture-proof, because when the buried light is working, the LED generates high heat, which makes the gas in the cavity of the buried light gradually expand, and the air pressure increases. The gas will slowly leak to the outside through the small gaps between the multi-strand rubber sleeves to ensure a certain balance between the internal and external air pressure. When the lamp stops working, the temperature in the cavity will drop, resulting in negative pressure, which will cause the external The water vapor slowly soaks into the lamp body through the gaps between the multi-strand rubber sleeves, which will easily cause the internal electronic components to absorb moisture and fail. This is the technical problem of waterproof and moisture-proof for LED underground lamps. Some start with multi-strand rubber sleeves and invent completely solid air-isolated thread ends, but they cannot solve the negative pressure problem and the cost is high; some add aluminum alloy waterproof and breathable valves, but once the aluminum alloy waterproof and breathable valves are soaked by sewage many times After that, the breathing membrane is prone to failure
