Description
Technical field
The utility model is related to the luminescent systems of vehicle lamp, and in particular to a kind of novel photocon luminescent system.
Background technology
Since LED light source has the advantages that apparent response is fast, and low energy consumption, 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 come into being, and the Φ of light guide is usually in 5mm-
Between 10mm, the space utilization of lamps and lanterns is more reasonable, and lamps and lanterns can also develop towards thinner direction, also be brought greatly to shape-designing person
Courage, arbitrarily, the design concept of family.
But light guide, as a kind of luminescence technology, luminous width is restricted, and can not meet shining for current moulding pursuit
Wider, light-emitting area bigger, shine the stronger lamps and lanterns appearance of visual effect level sense.
As shown in Figure 1, the photocon structural section schematic diagram to be used for vehicle lamp in the prior art, light is by basal plane
11 enter inside photocon, are come out after conduction along round light-emitting surface 12, that is, the light sent out using typical round light guide is preceding
Due to optical principle at square F, light is converged and then is propagated at F, if with units such as mirrors in front and rear placement at F, then human eye
When observing lamps and lanterns lighting vision, it is found that bright line occur with mirror in front of light guide, this bright line is since light convergence causes.Cause
This, existing circular light guide, luminous width has certain limitation.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of luminous width it is wider, it is light-emitting area bigger can
The photocon structure for vehicle lamp of the luminous visual effect of enhancing.
Its technical problem to be solved can be implemented by the following technical programs.
A kind of photocon structure for vehicle lamp, whole in strip structure, feature is the horizontal stroke of the strip structure
Substantially in toroidal, bell-mouthed port of export end face forms the light-emitting surface of the photocon, bell-mouthed side wall shape in section
Into the reflecting surface of the photocon, bell-mouthed input end connects light guide tooth, the trend of the light guide tooth and strip structure
Move towards consistent, the light guide tooth is provided at both ends with light source, and the end face of the horn mouth input end, which is formed, shines light source
Introduce the basal plane inside photocon；The light-emitting surface is a concave surface or the surface being integrally recessed.
As being further improved for the technical program, the surface that the light-emitting 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 the combination that both is.
As the further improvement of the technical program, the groove of a bar shaped is offered on the strip structure, it is described recessed
The slot bottom of slot forms the bottom surface of the basal plane, and the light guide tooth is whole or part is embedded in the groove.
Further, the slot bottom is plane.
One of preferred embodiment as the utility model, the cross section of the strip structure lack shape in the moon, lack shape knot the moon
The notch face of structure forms the light-emitting surface of the photocon.
Using the light-guiding system of the lamps apparatus for vehicle of above-mentioned technical proposal, a kind of photocon of polymorphic structure is provided,
With reference to light guide techniques, there is the performance of enhancing optronics visual effect.Luminous width is wider, light-emitting area bigger.

Specific embodiment
Specific embodiment of the present utility model 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, in order to solve the deficiencies in the prior art,
The circular configuration of the prior art is changed to anisotropic approach, concrete structure is as follows：
2 back side of photocon 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 light-emitting surface 22
Photocon is left, wherein, the section substantially moon of the opposite sex photocon lacks shape, and the surface of notch just forms light extraction
Face 22, that is, during the beam projecting of light guide, by light-emitting surface 22, due to optical principle, similar concavees lens act on, and light is directly sent out
It dissipates, can solve existing design can observe the interior deficiency with bright lines such as mirrors in front of lamps and lanterns.
Wherein, knife light ruler is embedded in a groove body, and the bottom surface of groove body forms basal plane 11, which is preferably plane.
Reflecting surface 23 and 24 is concave surface.
Embodiment 2：
As shown in figure 5, the structural representation for the utility model embodiment 2, as different from Example 1, photocon
The part of reflecting surface is the convex configuration of reflecting surface 23B and 24B inwardly projecting in figure.
Embodiment 3：
As shown in fig. 6, the structural representation for the utility model embodiment 3, as different from Example 2, though light-emitting surface 22C
A right generally concave surface, but be composed of multiple smaller concave surfaces, the size and radian of these smaller concave surfaces can phases
Etc. can not also wait.The concave surface of one entirety is decomposed into multiple smaller concave surfaces to be beneficial to realize that light transmission more should
With scene and improve its adaptability.
The above-mentioned different in nature photocon structure for being respectively used for vehicle lamp provided by the utility model, breaches in the prior art
Photocon non-circular (pole) can not tixed thinking, advantageously account for the specific problem and widening its application scenarios,
In terms of existing technologies, it effectively solves in front of light guide and the defects of bright line occurs with mirror.
