Problems solved by technology

[0006] In order to overcome the deficiency that the existing closed halogen tungsten automotive headlights can not take into account the light distribution performance and assembly adjustment space, the present invention provides a kind of low beam filament and high beam filament that can ensure that the halogen hair bubble can be in a reasonable position, ensuring It can get a better light shape when lighting, and can ensure that the reflector has a set depth, so as to fully ensure the utilization rate of the light energy emitted by the halogen bulb low beam and high beam filament, and at the same time ensure that the halogen bulb has enough light when assembling. The adjustment space is convenient for the production and assembly of the new type of closed halogen tungsten automotive headlights

Abstract

The invention relates to a novel closed-type halogen-tungsten automobile headlamp which comprises a lamp shade, a lamp body and a luminous body, wherein the internal surface of the lamp body is provided with a reflecting curved surface; the luminous body is installed on the back end of the lamp body; the front end of the lamp body is connected with the lamp shade; the center of the bottom of the reflecting curved surface is provided with a groove; and the tail of the luminous body is positioned in the groove. The novel closed-type halogen-tungsten automobile headlamp can realize higher light utilization ratio, obtain better lighting shape and ensure adequate adjustment space when a halogen bulb is assembled.

Description

technical field [0001] The invention belongs to automobile headlights, in particular to a closed halogen tungsten automobile headlight. Background technique [0002] The existing closed halogen tungsten automotive headlight structure includes a lampshade, a lamp body and a luminous body. The inner surface of the lamp body is provided with a reflective curved surface. The bottom of the lamp body is equipped with a luminous body, and the lamp body is connected to the lampshade. [0003] refer to figure 1 and figure 2 , the illuminant is usually equipped with H4 type halogen hair-foam illuminant. The H4-type halogen hair-foam illuminant includes low beam filament and high beam filament arranged in front and rear. There is a reflective bowl under the low beam filament. The double-filament light distribution performance of this structure is The premise guarantee and the best choice to meet the national standard. For bulbs with filaments arranged in front and behind, due to th...
