Abstract
An automobile headlamp comprises a lamp shell (2) and a reflector (3); the reflector (3) is arranged in the lamp shell (2) through an adjusting mechanism, and a mounting hole is formed in the bottom of the reflector (3); a bulb seat (4) capable of dissipating heat is fixedly arranged on the mounting hole, a bulb (5) is arranged in the bulb seat (4), and the light-emitting end of the bulb (5) is positioned in the reflector (3); the opening of the lamp shell (2) is hermetically connected with a lamp shade (1); the side surface of the reflector (3) above the bulb (5) is provided with a heat outlet (6), and a heat insulation sheet (7) is fixedly arranged at the heat outlet (6). The invention comprises the following steps: the reflector (3) and the lamp shell (2) are prevented from quality problems, the service life of the automobile lamp is prolonged, the use is safe, and the assembly is convenient.
Description
Technical Field
The invention relates to the technical field of automobile lamps, in particular to an automobile headlamp.
Background
The existing automobile front fog lamp comprises a reflector, a lamp shell, a bulb and a lamp shade, wherein the bulb is directly installed on the reflector. When the automobile front fog lamp is used, a large amount of heat can be generated when the lamp bulb is turned on, the temperature at the reflector is easily overhigh, the phenomenon that the aluminum coating on the surface of the reflector is colored occurs, the lamp shell at the position can be baked and melted at high temperature, the service life of the automobile front fog lamp is short, and the automobile front fog lamp is unsafe to use.
Disclosure of Invention
In view of the above-mentioned drawbacks, an object of the present invention is to provide an automobile headlamp, which dissipates heat through a heat outlet on a reflector to prevent the aluminum coating on the reflector from coloring due to an excessive temperature, and then prevents the lamp housing from melting through a heat insulation sheet installed at a corresponding portion of the lamp housing, thereby improving the service life of the automobile headlamp and ensuring safe use.
The technical scheme adopted by the invention is as follows: an automobile headlamp comprises a lamp shell and a reflector; the reflector is arranged in the lamp housing through the adjusting mechanism, and the bottom of the reflector is provided with an installation hole; a bulb seat capable of dissipating heat is fixedly arranged on the mounting hole, the bulb is arranged in the bulb seat, and the light-emitting end of the bulb is positioned in the reflector; the opening of the lamp shell is hermetically connected with a lamp shade; the method is characterized in that: the side surface of the reflector, which is positioned on the bulb, is provided with a heat outlet, and a heat insulation sheet is fixedly arranged at the heat outlet.
And a reflecting surface is arranged in the reflector.
The automobile lamp has a simple assembly structure, heat is dissipated through the heat outlet arranged on the reflector, the phenomenon that the aluminum coating on the surface of the reflector is colored due to overhigh temperature is avoided, the lamp shell is prevented from being melted through the heat insulation sheet arranged at the corresponding part of the lamp shell, the service life of the automobile lamp is prolonged, and the automobile lamp is safe to use.
Drawings
Fig. 1 is an exploded view of the structure of the present invention.
In the figure: 1 is a lampshade, 2 is a lamp shell, 3 is a reflector, 4 is a bulb seat, 5 is a bulb, 6 is a heat outlet, and 7 is a heat insulation sheet.
Detailed Description
For the purpose of enhancing the understanding of the present invention, the present invention will be further explained with reference to the accompanying drawings and examples, which are only for the purpose of explaining the present invention and do not limit the scope of the present invention.
As shown in fig. 1, an automotive headlamp includes a lamp housing 2 and a reflector 3; the reflector 3 is arranged in the lamp shell 2 through an adjusting mechanism, and a mounting hole is formed in the bottom of the reflector 3; a bulb seat 4 capable of dissipating heat is fixedly arranged on the mounting hole, a bulb 5 is arranged in the bulb seat 4, and the light-emitting end of the bulb 5 is positioned in the reflector 3; the opening of the lamp shell 2 is hermetically connected with a lamp shade 1; the reflector 3 is provided with a heat outlet 6 on the side surface above the bulb 5, and a heat insulation sheet 7 is fixedly arranged on the heat outlet 6. The assembly structure is simple, the heat is dissipated through the heat outlet 6 arranged on the reflector 3, the phenomenon that the aluminum coating on the surface of the reflector 3 is colored due to overhigh temperature is avoided, the heat insulation sheet 7 arranged at the corresponding part of the lamp shell 2 is used for preventing the lamp shell 2 from being melted, the service life of the automobile lamp is prolonged, and the automobile lamp is safe to use. The reflecting surface 32 is arranged in the reflector 3, so that when the lamp is used, the light-emitting brightness of the lamp is improved by the reflecting surface 32, and energy is saved.
The embodiments of the present invention are disclosed as the preferred embodiments, but not limited thereto, and those skilled in the art can easily understand the spirit of the present invention and make various extensions and changes without departing from the spirit of the present invention.
Claims (2)
