Description
Technical field
The utility model relates to a kind of vehicle LED dipped headlight structure of direct projection type, belongs to technical field of automobile illumination.
Background technology
At present, be that the dipped headlights optical system of light source mainly adopts the projection-type structure be made up of LED light source, ellipsoid optical reflector, light type baffle plate and lens with LED, in such an embodiment, dipped beam luminous intensity distribution light type mainly relies on light type baffle plate to shut out the light to be formed.But this structure is on the one hand because light type baffle plate causes larger luminous energy loss, and the efficiency of light energy utilization is lower, and structural volume is large, is the critical piece of luminous energy loss; This structure adopts the full reflector surrounded on the other hand, and collection efficiency is low and easily cause illumination above "cut-off"line excessive, causes luminous energy to waste.
Utility model content
The purpose of this utility model is for above-mentioned phenomenon, the utility model provides a kind of vehicle LED dipped headlight structure of direct projection type, this LED low-beam light structure not only makes existing LED low-beam light optical system be simplified, and reduces structural volume, and improves the efficiency of light energy utilization.
The utility model solves the technical scheme that its technical problem adopts:
A kind of vehicle LED dipped headlight structure of direct projection type, comprise sidelight lens, dipped headlights support, sidelight lens bracing frame, sidelight lens cover plate, semi-surrounding reflector, radiator, LED, described LED is arranged on the sphere centre place of the hemisphere face inner surface of sidelight lens rear end, be connected with radiator bottom LED, described semi-surrounding reflector and radiator are fixed on dipped headlights support, described sidelight lens front end is provided with two adjacent free form surface outer surfaces projectedly, described sidelight lens bracing frame is fixed on dipped headlights support, described sidelight lens rear end is fixed on optical lens bracing frame by sidelight lens cover plate.
Further, the angle of two adjacent free form surface outer surface boundary lines is 165 °.
The utility model utilizes the dipped beam light type that semi-surrounding reflector and hemisphere face inner surface realize the collection of luminous energy, free form surface outer surface realizes luminous energy to distribute, the high angle scattered light that LED is sent is directional light through semi-surrounding reflector reflects, again by lens reflection on photometric screen, the low-angle light that LED sends directly forms dipped beam light type through lens reflection, realizes the higher efficiency of light energy utilization.
The utility model advantage is:
1, decrease the light type baffle plate in existing LED low-beam light optical system, car headlamp system and device is simplified more.
2, under reducing light type baffle plate situation, utilize semi-surrounding reflector and free form surface sidelight lens to form "cut-off"line clearly, the efficiency of light energy utilization is high.

Detailed description of the invention
Be described in further detail utility model object of the present utility model below in conjunction with the drawings and specific embodiments, embodiment can not repeat one by one at this, but therefore embodiment of the present utility model is not defined in following examples.
As shown in Figures 1 to 8, a kind of vehicle LED dipped headlight structure of direct projection type, comprise sidelight lens 5, dipped headlights support 2, sidelight lens bracing frame 3, sidelight lens cover plate 4, semi-surrounding reflector 6, radiator 1, LED7, described LED7 is arranged on the sphere centre place of the hemisphere face inner surface 52 of sidelight lens 5 rear end, be connected with radiator 1 bottom LED7, described semi-surrounding reflector 6 and radiator 1 are fixed on dipped headlights support 2, described sidelight lens 5 front end is provided with two adjacent free form surface outer surfaces 51 projectedly, described sidelight lens bracing frame 3 is fixed on dipped headlights support 2, described sidelight lens 5 rear end is fixed on optical lens bracing frame 3 by sidelight lens cover plate 4.
The angle of two adjacent free form surface outer surface 51 boundary lines is 165
0.
As shown in Figure 9 and Figure 10, the dipped beam light type that semi-surrounding reflector 6 and hemisphere face inner surface 52 realize the collection of luminous energy, free form surface outer surface 51 realizes luminous energy is utilized to distribute, the high angle scattered light that LED7 is sent is directional light through semi-surrounding reflector reflects, again by lens reflection on photometric screen, the low-angle light that LED sends directly forms dipped beam light type through lens reflection, realizes high light energy utilization rate and compact.
Above-described embodiment of the present utility model is only for the utility model example is clearly described, and is not the restriction to embodiment of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all embodiments.All do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., within the protection domain that all should be included in the utility model claim.
