Embodiment 1
[0031] Embodiment 1: as figure 1 , and as shown in 2,
[0032] A reflector, comprising a cover body 1, the cover body 1 has a reflective cavity 2, the reflective cavity 2 has a gap 4 for installing a light source 3 or for light to enter the interior of the reflective cavity 2, and the reflective cavity 2 also There is an opening 5 for the emission of internal light, and the opening 5 of the reflection chamber 2 has a stepped edge 6 which matches the cut-off shape of the dipped beam.
[0033] The reflector of the present embodiment, when in use, the light source 3 of the present embodiment can be an LED light source, also can be the light source of other light-emitting forms, the light source 3 enters in the reflective cavity 2, then is emitted by the opening 5 of the reflective cavity 2, After being projected by the projection part 9 of the car lamp, the illuminated area of the car lamp is formed. Since the opening 5 of the reflector chamber 2 has a stepped edge 6, and the ...
Embodiment 2
[0041] Embodiment 2: as figure 1 and 2 as shown,
[0042] A vehicle lamp, comprising the reflector described in Embodiment 1 above, further comprising a projecting part 9 for projecting the shape of the edge of the opening 5 of the reflective cavity 2 to form an illumination area.
[0043] The car lamp of this embodiment, owing to adopting above-mentioned reflector, has simplified car lamp structure, has reduced manufacturing cost and improved reliability in use, moreover, has also avoided the shading of light by light shielding plate, has improved the utilization of the light that light source 3 emits. Rate.
[0044] Further, the projection component 9 is a lens.
[0045] Further, a light source 3 is also included.
[0046] Further, the light source 3 is located outside the reflector. The light source 3 is located outside the reflector, which can facilitate the arrangement of heat dissipation components and facilitate the heat dissipation of the light source 3 of the veh...

Abstract
The invention relates to the technical field of illumination and in particular relates to a reflective hood and an automobile lamp employing the same. The reflective hood comprises a hood body which is provided with a reflective chamber; the reflective chamber is provided with a notch for mounting a light source or introducing light rays to the reflective chamber; the reflective chamber is also provided with an opening for emitting inner light rays out; and the opening of the reflective chamber has a step-like edge, and the step-like edge is matched with the light and dark section shape of a dipped headlight. During use, by adopting the reflective hood, the pattern shape of the illuminating region thereof is controlled by the shape of the edge of the opening of the reflective chamber. Compared with a conventional automobile lamp structure, a light screen structure can be cancelled, so that the automobile lamp structure is simplified, the manufacturing cost is lowered and the using reliability is improved; and moreover, the light rays are prevented from being shielded by the light screen, so that the utilization ratio of the light rays emitted by a light source is improved.
Description
technical field [0001] The invention relates to the technical field of lighting, in particular to a reflector and a vehicle lamp using the reflector. Background technique [0002] In the field of automotive lighting technology, clear requirements are put forward for the luminous intensity and irradiation direction of high beam lighting, low beam lighting and fog lamps of motor vehicles. For the low beam of the headlights, it is required that the emitted light must form a clear cut-off line. For the formation of the cut-off line, the technology of shading is mainly used at present. The principle is that the light source emits Part of the light is blocked by setting a shading plate to form a light and dark area, and a light and dark cut-off line is formed at the junction of light and dark, so that the illuminated area meets the relevant standards. [0003] Although the formation principle of the above-mentioned cut-off line has been widely used in the current headlights, it s...
