Description
Technical field
The invention belongs to the auto parts and components field, relate to a kind of taillight, relate in particular to a kind of side and throw the LED taillight.
Background technology
The taillight of automobile develops into the LED taillight by Halogen lamp LED gradually now, and its life-span is longer, and the light type is photochromic all outstanding.The LED taillight generally has just throwing with side throws two kinds of arrangement forms, and the LED light source of just throwing the LED taillight is directly come out, and granular sensation is stronger, affects the attractive in appearance of integral body; The LED light source that side is thrown the LED taillight is hidden, and throws speculum by side the light of its emission is derived, and has improved aesthetic appearance, but side is thrown speculum with the extremely desirable zone of all light reflections, will cause the loss of luminous energy.Even part light is not thrown mirror reflects by side, and after this part light directly penetrated, it penetrated angle and does not meet laws and regulations requirement, also will be wasted.
Summary of the invention
The technical problem to be solved in the present invention, be to provide a kind of side and throw the LED taillight, and it can be collected and change its light path the light that does not meet laws and regulations requirement, thereby makes its final satisfy regulatory requirement, reduces optical energy loss.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
A kind of side is thrown the LED taillight, comprise the LED light source that is arranged on matrix, the shutter body that is positioned at LED light source the place ahead on light direction and the side that the light that LED light source sends reflects is thrown speculum, the total reflection lens that also comprises auxiliary bright dipping, this total reflection lens has the rectangular-shaped main body that vertically is arranged in LED light source side the place ahead, main body is the incident end near an end of LED light source, this incident end is provided with in the face of the plane of incidence of LED light source and back to the reflecting surface of the inclination of LED light source, and the plane of incidence and reflecting surface form wedge structure.
As limitation of the invention, the end away from LED light source of main body be provided with one outstanding, be used for fixing the link of this main body.
As to another kind of restriction the of the present invention, the end of incident end probes into to the inside that side is thrown the LED taillight to what make that described LED light source sends and throws without side the light that speculum reflects and directly outwards penetrate and all received by the plane of incidence.
As of the present invention the third limited, main body is bright and clean planar structure away from an end of LED light source.
The present invention also has a kind of restriction, and the fore-and-aft plane that described main body is thrown the LED taillight with respect to this side is obliquely installed.
Owing to having adopted above-mentioned technical scheme, compared with prior art, obtained technological progress is in the present invention:
Side provided by the present invention is thrown the LED taillight, be provided with the total reflection lens of auxiliary bright dipping, it collects the luminous energy that LED light source is wasted, after changing its light path, make the requirement of light satisfy regulatory, reduce optical energy loss, the main body of this total reflection lens is rectangular-shaped and vertical layout, can reduce the impact on ordinary ray; Outstanding link is set on main body, is convenient to the connection to main body; The end of incident end probes into the light that directly outwards penetrates without side throwing speculum reflects that sends to described LED light source and is received by the plane of incidence, can to large extent light be absorbed, and minimizing is on the impact of ordinary ray; Main body is bright and clean planar structure away from an end of LED light source, can guarantee the intensity that light penetrates, and reduces the loss of luminous energy through main body the time; Main body is obliquely installed, and can make and be easier to light generation total reflection.
The present invention is applicable on various automobiles.
The present invention is described in further detail below in conjunction with Figure of description and specific embodiment.

The specific embodiment
EmbodimentA kind of side is thrown the LED taillight
Side of the prior art is as shown in Figure 1 thrown the LED taillight, comprises the LED light source 1 that is arranged on matrix 4, is positioned at the shutter body 2 in LED light source 1 the place ahead and side that light that LED light source 1 is sent reflects is thrown speculum 3 on light direction.The light of LED light source 1 emission will have part directly to penetrate, the ejaculation angle of these light does not meet laws and regulations requirement, and after some was thrown speculum 3 reflections by side, its angle did not meet laws and regulations requirement yet, these light are the equal of to be wasted, and have caused the loss of luminous energy.
The side of the present embodiment is thrown the LED taillight as shown in Figures 2 and 3, it is on the basis of above-mentioned prior art, increased the total reflection lens of an auxiliary bright dipping, this total reflection lens provides to be collected and changes the luminous energy of loss, its requirement according to rules is penetrated, undertaken on reflective basis by side throwing speculum 3 main, this total reflection lens only has been to provide some compensating actions, has reduced the loss of luminous energy.The effect of the total reflection lens of using in the present embodiment is different from just throws total reflection lens used in the LED taillight, because the total reflection lens of just throwing in the LED taillight is main reflecting part, and be only used in the present embodiment compensating, it must be thrown speculum 3 in conjunction with side and carry out work.
This total reflection lens has the rectangular-shaped main body 51 that vertically is arranged in LED light source 1 side the place ahead, main body 51 is the incident end near an end of LED light source 1, this incident end is provided with in the face of the plane of incidence 53 of LED light source 1 and back to the reflecting surface 52 of the inclination of LED light source 1, and the plane of incidence 53 forms wedge structures with reflecting surface 52.
Be provided with one at the end away from LED light source 1 of main body 51 and outstanding be used for fixing the link 54 of this main body 51.Wherein, the longitudinal direction that this side is thrown the LED taillight refers to the direction that light is finally penetrated, and light can be considered to directional light while finally being penetrated, and the axis direction of these directional lights and LED light source 1 is perpendicular.By the angle between reflecting surface 52 and the plane of incidence 53 is set, after making light enter the inside of main body 51 by the plane of incidence 53, total reflection occurs on reflecting surface 52, then, the light of these incidents finally penetrates after the internal face of main body 51 inside is proceeded repeatedly total reflection, be positioned at the functional areas of laws and regulations requirement by the zone after penetrating.Main body 51 is bright and clean planar structure away from an end of LED light source 1, is conducive to light and penetrates fully.
The fore-and-aft plane that main body 51 is thrown the LED taillight with respect to the side of the present embodiment is obliquely installed, and makes to enter that its inner light is easier carries out total reflection at reflecting surface 52, and the fore-and-aft plane at this place is to throw the plane longitudinally of LED taillight along unitary side.
in order to large extent the luminous energy that loses to be absorbed, the end of incident end probes into to the inside that the side of the present embodiment is thrown the LED taillight to what described LED light source 1 sent and throws without side the light that speculum 3 reflects and directly outwards penetrate and all received by 53 of the planes of incidence, like this, the concrete shape of main body 51 and size can be resulting by method of geometry, improved on the one hand the collecting effect of luminous energy, also be convenient on the other hand manufacture and design, can also reduce the impact of main body 51 on ordinary ray, can unhinderedly arrive side because normal light can not be subject to the impact of incident end and throw speculum 3.
