Description
Technical field
The present invention relates to the luminescent system of vehicle lamp, and in particular to a kind of new photocon luminescent system.
Background technology
Because LED light source has the advantages that obvious response is fast, and energy consumption is low, chroma stability, lamps apparatus for vehicle is more next at present
More uses LED light source.Under the development of LED application technologies, light guide techniques are arisen at the historic moment, and the Φ of light guide is generally in 5mm-
Between 10mm, the space utilization of light fixture is more reasonable, and light fixture can also develop towards thinner direction, also be brought greatly to shape-designing person
Courage, arbitrarily, the design concept of family.
But light guide is restricted as a kind of luminescence technology, luminous width, it can not meet that current moulding is pursued luminous
Wider, light-emitting area is bigger, the stronger light fixture outward appearance of the visual effect that lights level sense.
As shown in figure 1, to be used for the photocon structural section schematic diagram of vehicle lamp in the prior art, light is by basal plane
11 enter inside photocon, are come out after conduction along circular exiting surface 12, i.e. the light sent using typical round light guide is preceding
Due to optical principle at square F, light is converged and then propagated at F, if with units such as mirrors in front and rear placement at F, then human eye
When observing light fixture lighting vision, it is found that bright line occur with mirror in front of light guide, this bright line is due to that light collection causes.Cause
This, existing circular light guide, its luminous width has certain limitation.
The content of the invention
The technical problems to be solved by the invention are to provide that a kind of luminous width is wider, light-emitting area is bigger strengthens
The photocon structure for vehicle lamp of luminous visual effect.
Its technical problem to be solved can be implemented by the following technical programs.
A kind of photocon structure for vehicle lamp, overall is in list structure, and its feature is the horizontal stroke of the list structure
Section is substantially in toroidal, and bell-mouthed port of export end face forms the exiting surface of the photocon, bell-mouthed side wall shape
Into the reflecting surface of the photocon, bell-mouthed entrance point connects light guide tooth, the trend of the light guide tooth and list structure
Move towards consistent, the light guide tooth is provided at both ends with light source, and the end face of the horn mouth entrance point, which is formed, lights light source
The basal plane introduced inside photocon；The exiting surface is a concave surface or the surface being integrally recessed.
As the further improvement of the technical program, the surface that the exiting surface is integrally recessed is laid with multiple sizes or arc
Spend uniformly or non-uniformly concave surface.
As the further improvement of the technical program, the reflecting surface is concave surface or convex surface or is both combinations.
As the further improvement of the technical program, the groove of a bar shaped is offered on the list structure, it is described recessed
The bottom land of groove forms the bottom surface of the basal plane, and the light guide tooth is overall or part is embedded in the groove.
Further, the bottom land is plane.
As one of the preferred embodiments of the present invention, the cross section of the list structure lacks shape in the moon, lacks shape structure by the moon
Breach face forms the exiting surface of the photocon.
Using the light-guiding system of the lamps apparatus for vehicle of above-mentioned technical proposal, there is provided a kind of photocon of polymorphic structure,
With reference to light guide techniques, it has the performance of enhancing optronics visual effect.Luminous width is wider, light-emitting area is bigger.

Embodiment
The embodiment of the present invention is described in further detail below in conjunction with the accompanying drawings.
Embodiment 1：
The photocon structure for vehicle lamp as shown in Figures 2 to 4, its in order to solve the deficiencies in the prior art,
The circular configuration of prior art is changed to anisotropic approach, concrete structure is as follows：
The back side of photocon 2 of strip is embedded with light guide tooth 3, and light guide tooth 3 is provided at both ends with light emitting source, light emitting source institute
The optically coupled face of light of hair --- basal plane 21 enters inside photocon 2, the reflection through reflecting surface 23 and 24, along exiting surface
22 leave photocon, wherein, the section substantially moon of the different in nature photocon lacks shape, and the surface of its breach just forms out
Smooth surface 22, i.e. during the beam projecting of light guide, by exiting surface 22, due to optical principle, similar concavees lens act on, and light is direct
Diverging, can solve existing design can observe the interior deficiency with bright lines such as mirrors in front of light fixture.
Wherein, knife light chi is embedded in a cell body, and the bottom surface of cell body forms basal plane 11, and the basal plane is preferably plane.
Reflecting surface 23 and 24 is concave surface.
Embodiment 2：
As shown in figure 5, be the structural representation of the embodiment of the present invention 2, as different from Example 1, the reflection of photocon
The part in face is reflecting surface 23B and 24B inwardly projecting in figure convex configuration.
Embodiment 3：
As shown in fig. 6, being the structural representation of the embodiment of the present invention 3, as different from Example 2, exiting surface 22C is although whole
Body is a concave surface, but is combined by multiple smaller concave surfaces, and the size and radian of these smaller concave surfaces can be with equal
It can not wait.The concave surface of one entirety is decomposed into multiple smaller concave surfaces to be beneficial to realize that light transmits more applied fields
Scape and its adaptability of raising.
The above-mentioned different in nature photocon structure for being respectively used for vehicle lamp provided by the invention, breaches light guide in the prior art
Element non-circular (pole) can not tixed thinking, advantageously account for specific produced problem and widening its application scenarios, relatively
For prior art, effectively solve in front of light guide and the defects of bright line occur with mirror.
