Description
Technical field
The present invention relates to lighting technical field, and in particular to a kind of reflection shield and the car light using the reflection shield.
Background technology
In technical field of automobile illumination, the luminous intensity and photograph of far lighting, lower beam illumination and fog lamp to motor vehicle
Penetrate direction and propose and clearly require.For the dipped headlight of headlamp, it is desirable to which emitted light necessarily be formed clearly bright
Dark dead line, and for the formation of the "cut-off"line, presently mainly carries out shading this technology, its principle using shadow shield
It is that the light that light source is launched is blocked by setting shadow shield to some light, and then forms a light and shade region,
Penumbra forms a "cut-off"line, in this way, making its illuminated area meet the regulation of relevant criterion.
The formation basic theory of above-mentioned "cut-off"line, although be widely used among current headlamp at present,
But it still has the technological deficiency that can not avoid, and is embodied in the problem of its light utilization efficiency, i.e. current automobile
The structure of dipped headlight is typically to include light source and for blocking the irradiant shadow shield of light source, and the light that light source sends is wherein
A part is blocked plate and blocks, do not participate in illumination work in so that at present said structure headlamp, its light profit
It is not high with rate.
So, based on above-mentioned, need a kind of Vehicle lamp structure that can improve light utilization efficiency badly at present.
The content of the invention
It is an object of the invention to：For current car light, when "cut-off"line is formed, existing light is blocked plate screening
Gear, and cause light to utilize problem not high, there is provided one kind can form "cut-off"line, light source can be improved again and is emitted beam profit
With the Vehicle lamp structure of rate.
To achieve these goals, the technical solution adopted by the present invention is：
A kind of reflection shield, including cover body, the cover body have reflection cavity, and the reflection cavity has for installing light source or being used for
Light enters the breach of reflective cavity, and the reflection cavity also has the opening projected for internal light, the reflection cavity
Opening has a step-like edge, and the step-like edge matches with the light and shade cut-off shape of dipped headlight.
The reflection shield of the application, when in use, light source is entered into reflection cavity, then is projected by the opening of reflection cavity, through car
The illumination region of car light is formed after the projection part projection of lamp, due to there is step-like edge in reflection cavity opening, and, platform
The edge of scalariform matches with the shape of the light and shade cut-off region of dipped headlight, so, in actual use, when light is by reflection cavity
Opening project after, the opening of reflection cavity is projected through projecting part, you being formed has "cut-off"line illumination region, also
It is to say, using the reflection shield of the application, the pattern form of its illumination region is that have the edge shape of reflection cavity opening to control, compared with
For traditional Vehicle lamp structure, anti-dazzle plate structure can be omitted between, in this way, being a simplified Vehicle lamp structure first, reduce manufacture
Cost and raising use reliability, and, it is thus also avoided that shadow shield is blocked to light, improves the utilization that light source emits beam
Rate.
Preferably, the inwall of the reflection cavity includes that one end is larger, and the bowl-shape reflecting surface of the other end less half is described
