Specific embodiment

It is illustrated below in conjunction with preferred embodiment of the attached drawing to the utility model, it should be understood that described herein excellent It selects embodiment to be only used for describing and explaining the present invention, is not used to limit the utility model.

In the description of the present invention, it should be noted that the instructions such as term "vertical", "upper", "lower", "horizontal" Orientation or positional relationship is to be based on the orientation or positional relationship shown in the drawings, and is merely for convenience of description the utility model and simplification Description, rather than the device or element of indication or suggestion meaning must have a particular orientation, constructed and grasped with specific orientation Make, therefore should not be understood as limiting the present invention.

In the description of the present invention, it should also be noted that, unless otherwise clearly defined and limited, term " is set Set ", " installation ", " connected ", " connection " shall be understood in a broad sense, for example, it may be being fixedly connected, may be a detachable connection, Or it is integrally connected；It can be mechanical connection, be also possible to be electrically connected；It can be directly connected, intermediary can also be passed through It is indirectly connected, can be the connection inside two elements.It for the ordinary skill in the art, can be according to specific feelings Condition understands the concrete meaning of above-mentioned term in the present invention.

Embodiment: as shown in Figure 1-3, the utility model provides a kind of automobile dipped headlight reflector, including reflector cup body 1, LED light board mount 2 and filtering apparatus 3；The reflector cup body 1 include barn door 11 and reflective surface 12, barn door 11 In 12 front of reflective surface, there are LED lamp panel positioning pin 13 and the first LED lamp panel fixation hole 14 on the reflector cup body 1；It is described LED light board mount 2 includes LED lamp panel 21, LED lamp panel location hole 23 and the second LED lamp panel fixation hole 24, and the LED lamp panel is fixed Position and is worked in coordination at hole 23 with LED lamp panel positioning pin 13, and the first LED lamp panel fixation hole 14 and the second LED lamp panel fixation hole 24 are mutually It matches, filtering apparatus 3 is installed in LED lamp panel 21, LED light source 22 is mounted on inside filtering apparatus 3.

Further, the filtering apparatus 3 includes shell 32, ultraviolet light filter layer 31, cooling fin 33, and the dew, which filters, to be filled 3 are set in appearance rectangular parallelepiped structure, LED lamp source 22 is installed on bottom surface, and 3 bottom of filtering apparatus is equipped with equally distributed heat dissipation Piece 33, ultraviolet light filter layer 31 package covering LED light source 22 be mounted on filtering apparatus 3, the ultraviolet light filter layer 31 be by It filters made of uviol.

Further, the reflective surface 12 is oval calotte, is coated with one layer of vacuum aluminium coated layer, shading on reflective surface 12 The position of plate 11 is in the oval calotte focus of reflective surface 12, and LED light source 21 is located at the oval calotte of reflective surface 12 In another focus.

Specific: LED light source 22 and barn door 11 are located in the elliptical focus in reflective surface place, and ellipse has this The optical properties of sample, the light source issued from a focus pass through the reflection of ellipsoid, and reflected light can pass through second focus.So The light that LED light source 22 and barn door 11 are arranged in this way can allow LED light source 22 to emit all passes through near barn door 11, passes through manipulation Barn door 11 just can be carried out controls the light of light source well.
