Including LED light source and lens, lens set up the position that sends mixed light outward diffusion at the LED light source, pass through the outside of lens is provided with the filtering structure, and the filtering structure is the filter coating, the filter coating subsides cover on the surface of lens to one side that deviates from the LED light source, the filtering structure is the filter plate, the filter plate subsides cover on the surface of lens, and with the adjacent one side of light source, solved most car light lens light and shade cut-off line edge and sent yellow bluish, shine the unclear problem of cut-off line, eliminated LED short-distance cut-off line edge and sent yellow bluish phenomenon, make the nearly light shine more evenly softer on the road surface. The visual effect is better, and this practical structure design is simple reasonable, has better use prospect.

Description

Low beam PES filtering mechanism of automobile headlamp

Technical Field

The utility model relates to a car light technical field specifically is an automotive headlamps low beam PES optical filtering mechanism.

Background

With the continuous advancement of automotive lamp technology today, automotive lamp light sources have been gradually selected from incandescent bulbs, halogen bulbs, gas discharge bulbs, LEDs, lasers. Vehicle lights with LED light sources have been commonly used in existing and new vehicle models, plus most low beam light is LED in conjunction with a lens.

The wavelength of the visible light spectrum is 380 nm-780 nm, the visible light spectrum is seven colors of light which can be sensed by human eyes, and the light with different wavelengths is caused by different refractive indexes of the same material. Most car light lens bright and dark cut-off line edge is luminous bluish at present, as shown in figure 1, this practicality is also for solving the lens of car light type colour problem, through increasing filtering structure at lens, filters blue light and yellow light, makes the cut-off line more clear.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art, the utility model provides an automobile headlamp passing beam PES optical filtering mechanism has solved the problem to the solution of car light cut-off line chromatic dispersion problem.

In order to achieve the above purpose, the utility model discloses a following technical scheme realizes: the utility model provides an automobile headlamps low beam PES filtering mechanism, includes LED light source and lens, the lens setting is in the position of the outside diffusion of the mixed light that the LED light source sent, the outside of lens is provided with filtering structure.

Preferably, the light filtering structure is a light filtering film, and the light filtering film is attached to the surface of the lens and faces away from one side of the LED light source.

Preferably, the light filtering structure is a light filter plate, and the light filter plate is attached to the surface of the lens and is adjacent to one side of the light source.

Advantageous effects

The utility model provides an automobile headlamp dipped beam PES optical filtering mechanism. Compared with the prior art, the method has the following beneficial effects:

the utility model provides an automobile headlamps low-beam PES optical filtering mechanism, through including LED light source and lens, lens setting sends the mixed light outward diffusion's position at the LED light source, the outside of lens is provided with the filtering structure, the filtering structure is the filter coating, the surface at lens is pasted to the filter coating, and deviate from one side of LED light source, the filtering structure is the filter plate, the filter plate is pasted and is covered on the surface of lens, and adjacent one side with the light source, most car lamp lens light and shade cut-off line edge yellow bluing has been solved, shine the problem that the cut-off line is not clear, the phenomenon that LED low-beam cut-off line edge yellowish bluing has been eliminated, make the near-light shine more evenly gentler on the road surface, visual effect is better.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Example 1

Referring to fig. 2, the present invention provides a technical solution: the utility model provides a vehicle headlamps low beam PES optical filtering mechanism, includes LED light source 1 and lens 3, and lens 3 sets up in the position that LED light source 1 sent mixed light 2 outdiffusion, and the outside of lens 3 is provided with filter coating 6, and filter coating 6 pastes the surface of covering at lens 3 to deviate from one side of LED light source 1, LED light source 1 sends mixed light 2, and mixed light 2 sees through lens 3 and filter coating 6 and obtains white light 5.

Example 2

Referring to fig. 3, the present invention provides a technical solution: the utility model provides a vehicle headlamps low beam PES optical filtering mechanism, includes LED light source 1 and lens 3, and lens 3 sets up in the position that LED light source 1 sent mixed light 2 outdiffusion, and the outside of lens 3 is provided with filter plate 7, and filter plate 7 pastes the surface of covering at lens 3 to with the adjacent one side of light source, LED light source 1 sends mixed light 2, and mixed light 2 sees through lens 3 and filter plate 7 and obtains white light 5.

The embodiment 1 and the embodiment 2 have the same thing in that the yellow and blue light 4 in the mixed light 2 emitted by the LED light source 1 can be filtered, and the mixed light 2 emitted by the LED light source 1 only obtains the white light 5 after passing through the lens 3 and the filtering structure, so that the phenomenon that the edge of the cut-off line of the LED dipped beam is yellow and blue is eliminated, the near light is more uniform and softer on the road surface, and the visual effect is better.

The filter 6 of embodiment 1 is attached to the outer side of the lens 3 (car headlight), after long-term use, the external environment is complicated, the filter 6 will be worn, and needs to be replaced frequently, increasing the use cost, and compared with embodiment 1, embodiment 2 has the advantage that the filter 7 of embodiment 2 is disposed on the inner side of the lens 3 (car headlight), so that the problem of too fast self-damage due to the bad external environment will not occur, therefore the replacement frequency of the filter structure can be reduced, the service life can be prolonged, and the cost can be reduced.

It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions.
