Abstract

The invention provides a novel automotive tail light with a combined optical system. The novel automotive tail light comprises an LED light source arranged on a reflection face. A first layer of light guide, a second layer of total reflection optical internal lens structure and a third layer of lens are sequentially arranged in front of the LED light source. The automotive tail light with the total reflection optical internal lens combined optical system is formed by combining a common LED, the light guide, the total reflection optical internal lens structure and the lens, light at any angle is totally reflected onto the front emergent face through a total reflection optical internal lens, and thus a step effect is formed.

Description

A kind of automobile tail light of NEW TYPE OF COMPOSITE optical system
Technical field
The present invention relates to a kind of optical system being applied to automobile tail light design, realize lighting the automobile tail light that outward appearance is stepped effect.
Background technology
Along with making rapid progress of automobile lamp technical development, needing the car light that designs can outside strictly satisfy regulatory requires, car load client particularly lights effect to the appearance requirement of car light and more and more payes attention to, to some degree, a beautiful car light outward appearance can promote rapidly the visual experience of a car, current automobile tail light is except using common bulb as except light source, it is general that the selecting of LED light source has also become very, select LED as light source by the design to lens, multiple moulding can be realized, but quoting at optical lens, existing technology can't cause visual impact to feel and third dimension, beyond thought effect cannot be reached.
Summary of the invention
Automobile tail light of the present invention needs to select common LED light source in the appearance reaching stepped effect usually, lens in cooperation photoconduction, speculum and ATR Optical, thus cause the effect visually having multiple ladder, a kind of automobile tail light of 3D effect is provided.
Technical scheme of the present invention there is provided a kind of automobile tail light of NEW TYPE OF COMPOSITE optical system, include installation LED light source on the mirror, the outer lens of lens and third layer in the ATR Optical that the front of described LED light source is disposed with the photoconduction of ground floor, the second layer, in described ATR Optical, the surface of lens is set to step-like.
Further improvement is: after described photoconduction is lit, the light that photoconduction sends some enter the rear surface of lens in ATR Optical.
Further improvement is: described LED light source by speculum by the rear surface of photoconduction to lens in ATR Optical.
Further improvement is: the light that described photoconduction sends and the light that LED light source sends all enter into the rear surface of lens in ATR Optical, utilize total reflection effect, in ATR Optical lens the light of bottom reflection some is arrived lens in ATR Optical step transmission, most light is separately had to transmit from the front end face of lens in ATR Optical, transmit through outer lens again, form stepped effect.
The invention has the beneficial effects as follows: the present invention combines by using lens and outer lens in common LED light source, photoconduction, ATR Optical, the light that the light sent by photoconduction and LED light source are sent enters into lens in ATR Optical, in ATR Optical, the light of all angles is fully reflexed to step and front surface (front exit facet) by the bottom surface of lens, thus forms 3D stepped effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the Ray tracing figure of lens in ATR Optical of the present invention.
Fig. 3 is the close-up schematic view of lens in ATR Optical of the present invention.
Wherein: 1-speculum, 2-LED light source, 3-photoconduction, lens in 4-ATR Optical, 5-outer lens, lens surface in the ATR Optical that 6-is step-like, the front end face of lens in 7-ATR Optical.
Detailed description of the invention
In order to deepen the understanding of the present invention, below in conjunction with embodiment, the invention will be further described, and this embodiment only for explaining the present invention, does not form limiting the scope of the present invention.
As shown in Figure 1, 2, 3, present embodiments provide a kind of automobile tail light of NEW TYPE OF COMPOSITE optical system, include the LED light source 2 be arranged on speculum 1, the outer lens 5 of lens 4 and third layer in the ATR Optical that the front of described LED light source 2 is disposed with the photoconduction 3 of ground floor, the second layer, in described ATR Optical, the surface of lens 4 is set to step-like 6.After described photoconduction 3 is lit, the light that photoconduction 3 sends some enter the rear surface of lens 4 in ATR Optical.Described LED light source 2 passes through speculum 1 by the rear surface of photoconduction to lens in ATR Optical 4.The light that photoconduction 3 sends and the light that LED light source 2 sends all enter into the rear surface of lens 4 in ATR Optical, utilize total reflection effect, in ATR Optical lens 4 the light of bottom reflection some is arrived lens in ATR Optical step 6 transmission, most light is separately had to transmit from the front end face 7 of lens in ATR Optical, shoot out through outer lens saturating 5 again, form stepped effect.
The present invention combines by using lens and outer lens in common LED light source, photoconduction, ATR Optical, the light that the light sent by photoconduction and LED light source are sent enters into lens in ATR Optical, in ATR Optical, the light of all angles is fully reflexed to step and front surface (front exit facet) by the bottom surface of lens, thus forms 3D stepped effect.
