Motorcycle LED headlamp

Abstract

The invention discloses a motorcycle LED (Light Emitting Diode) headlamp. The motorcycle LED headlamp comprises a lamp housing, a lens positioned at the front end of the lamp housing and a lighting structure positioned in the lamp housing, wherein an annular mounting plane is arranged at the front end of the lamp housing, one circle of mounting rim is arranged on the edge of the mounting plane, the bottom of the lens is mounted on the mounting plane, a water-proof decorative cover is arranged at the periphery of the lens, the water-proof decorative cover is provided with a circle of cylindrical part arranged in the horizontal direction, the cylindrical part is fitted with the outer surface of the mounting rim through threads and provided with a hot melt adhesive, a vertically arranged annular part is arranged at the front part of the water-proof decorative cover, an annular step surface for seal is arranged on the inner surface of the annular part, the step surface is fitted with an annular step surface on the edge of the lens through clamping, and a hot melt adhesive is arranged on the fit surface. The motorcycle LED headlamp has the advantages of simple structure, convenient and rapid lens mounting, great water-proof effect, simpler lighting structure, small space occupation, great heat radiating effect, long service life and the like.

Description

technical field [0001] The invention relates to a motorcycle lighting device. It particularly relates to a motorcycle LED headlight. Background technique [0002] In existing motorcycles, in order to facilitate driving at night, headlights are provided on the front of the car, and the installation standard requires that the headlights need to have a high-beam function and a low-beam function. [0003] The headlights used in existing motorcycles generally have a structure including a lamp housing, a lens is arranged at the front end of the lamp housing, and an illumination structure composed of lamp beads and reflective bowls is arranged inside the lamp housing. Among them, when the lens is installed, the front part of the lamp housing is generally formed into one body with the lens by secondary forming; Water, but the installation of the lens is inconvenient, and at the same time, the connection between the front part of the lamp housing and the main part is not waterproof...

AI Technical Summary

Problems solved by technology

Among them, when the lens is installed, the front part of the lamp housing is generally formed into one body with the lens by secondary forming; Water, but the installation of the lens is inconvenient. At the same time, the connection between the front part of the lamp housing and the main part is not waterproof. As a result, when driving in rainy days, rainwater easily enters the inside of the lamp housing, causing a short circuit

[0004] In addition, in the existing motorcycle headlights, the lighting structure generally consists of two sets of independent lamp beads and reflective bowls to complete the high beam function and the low beam function. The iron dimming mechanism is used to convert the far / low beam, which makes the headlight generate a lot of heat. At the same time, the existing headlight does not have a special heat dissipation structure, and the heat dissipation effect is poor, causing the lighting structure to be in a high temperature state for a long time, causing the LED to produce Light decay phenomenon, which greatly affects the LED lighting effect and service life
