The previous requirements for halogen foglight have failed to meet the requirements and must be changed. Particularly for the rear fog lamp of the vehicle, because the rear fog lamp is just positioned near an exhaust pipe of the vehicle, high-temperature tail gas discharged by the exhaust pipe of the vehicle and heat of the halogen lamp are required to be higher for heat resistance of the rear fog lamp. Meanwhile, the mounting position of the rear fog lamp is not only provided with an automobile anti-collision beam and a tail lamp assembly, but also limited in space, and the difficulty is improved by improving the rear fog lamp.

The specific embodiment is as follows:
The utility model will be further described with reference to specific examples and figures.
The utility model relates to a heat-resistant automobile halogen fog lamp, in particular to a rear fog lamp of an automobile. As shown in fig. 1 to 5, the present utility model includes: a lamp housing 1, a lamp shade 2 and a lighting assembly 3. The lamp housing 1 and the lamp shade 2 are fixedly connected with each other to form a cavity, and the halogen lamp cap 31 in the light-emitting assembly 3 is positioned in the cavity.
The lamp housing 1 can be formed by injection molding of polycarbonate material. The lamp housing 1 is bowl-shaped in its entirety and has a curved surface portion 11 for light reflection. The inner surface of the curved surface portion 11 serves as a reflecting surface for lamp light. In order to improve the light reflectivity, the inner surface of the curved surface portion 11 of the lamp housing 1 is formed with a reflective pattern, for example, the inner surface of the curved surface portion 11 is formed by small reflective surfaces distributed in a row. Meanwhile, the inner surface of the curved surface part 11 can be aluminized, the light reflectivity is further improved through the aluminum layer, and the influence of lamplight irradiation heat on the lamp housing is reduced.
The opening end of the lamp housing 1 is used as a butt joint part with the lamp housing 2, and a plurality of clamping holes 110 or clamping grooves are formed in the edge of the opening end.
The side of the lamp housing 1 is provided with a lamp cap hole 12 into which a halogen lamp cap 31 extends. The burner opening 12 is located in the region of the curved surface 11 and is located laterally over the entire lamp envelope 1. The utility model does not adopt the traditional method to directly form the lamp cap hole at the center of the reflecting curved surface, so as to save the space behind the fog lamp and facilitate the subsequent vehicle assembly. At the same time, the burner aperture 12 is in a lateral orientation, which is located in a difficult to view area, without compromising the integrity of the entire reflective surface. In the mounting, the halogen cap 31 is only required to be positioned in the focal region of the reflecting surface.
In addition, an air hole 13 is formed in the lamp housing 1, and a bearing plate 14, a connecting plate 15 and a wire clamping plate 16 are arranged on the outer side surface of the lamp housing 1. An air duct 131 extending outwards is arranged on the outer surface of the lamp housing 1 from the position of the air hole 13, and an air ventilation cover 4 is arranged on the air duct 131 in a covering mode. The function of this air hole 13 is: when the fog lamp works, after the air in the cavity is heated and expanded, part of heat can be taken out by part of air through the air holes 13 so as to reduce the temperature in the cavity. In addition, in order to facilitate protection of the ventilation cap 4, a shroud 132 for surrounding the ventilation cap 4 may be provided on the periphery of the air duct 131.
The lamp shade 2 is directly irradiated by the lamp tube, so that the lamp shade 2 can adopt a high-temperature-resistant PMMA-HT material, the Vicat softening temperature can reach 118 ℃, and the lamp shade has higher heat resistance while the light transmittance is maintained. The lamp cover 2 includes an integrally formed connection portion 21 and an outwardly extending protrusion 22. The connecting portion 21 is used for abutting against the lamp housing 1, and a clamping protrusion 210 or a clamping plate corresponding to the clamping hole 110 or the clamping groove is arranged at the edge of the connecting portion 21. The lamp housing 1 is fixedly connected with the lamp shade 2 through the fastening structure. In order to maintain the seal, a sealant is provided at the junction of the two.
As shown in fig. 1 and 5, in the lamp housing 2, the area of the connecting portion 21 is larger than the protruding portion 22, wherein the protruding portion 22 is used as a visible portion of the utility model which is finally assembled to the automobile. The light emitted by the halogen burner 31 in the light emitting assembly 3 is reflected by the reflecting surface in the housing 1 and is radiated by the protrusion 22.
The projection of the connecting portion 21 forms a partial shielding for the curved surface portion 11 of the lamp housing 1, the air hole 13 is opened in the area where the curved surface portion 11 is shielded, specifically, the connecting portion 21 forms a shielding for the upper part area of the surface portion 11, and the air hole 13 is opened in the upper part area of the curved surface portion 11. This design is adopted because: as described above, since the protruding portion 22 is the visible portion of the present utility model after final assembly to the automobile, the area blocked by the connecting portion 21 will be difficult to observe from the visible portion, so that the overall visual appearance of the present utility model will not be affected.
In addition, as shown in fig. 5, in order to facilitate the uniform lighting effect of the lamp shade 2, lines are formed on the inner surface of the lamp shade 2.
The light emitting assembly 3 includes: the halogen lamp cap 31 is connected with the plug part 33 through the lead wire 32, and the halogen lamp cap 31 is provided with a lamp cap seat 311 and a halogen lamp body 312 which are in buckling connection with the lamp cap hole 12.
For ease of installation, the wires 32 and the plug portions 33 in the light emitting assembly 3 are connected to the lamp housing 1. In combination with the foregoing, the carrying plate 14 is disposed on the outer side of the lamp housing 1, and the plug portion 33 is fixedly connected to the carrying plate 14. The wire clamping plate 16 is arranged on the outer side face of the lamp housing 1, and the wires 32 are clamped by the wire clamping plate 16.
In addition, the outer side surface of the lamp housing 1 is provided with fixing connection plates 15 along at least two different directions, for example, the utility model is provided with one connection plate 15 along the upper, left and right directions, and the connection plate 15 is used for fixing the utility model to the assembly of the automobile.
It is understood that the foregoing description is only illustrative of the present utility model and is not intended to limit the scope of the utility model, but rather is to be accorded the full scope of all such modifications and equivalent structures, features and principles as set forth herein.
