Abstract
The utility model discloses a light guide structure for an automobile gear panel. The light guide structure for the automobile gear panel comprises LED light sources, light guide parts and a gear character surface cover, wherein different characters on the gear character surface cover correspond to the different LED light sources, and light of the different LED light sources is transmitted to the gear character surface cover through the light guide parts. The portions between the light incidence ends and the light reflection ends of the light guide parts are of arc structures, and reflection curved surfaces are formed inside the light guide parts through the arc structures. The light guide structure for the automobile gear panel has the advantages that the problems of brightness loss and poor uniformity are solved by designing the light guide parts on the light sources; according to the light refraction and reflection principle, the light is emitted to the incidence surfaces of the light guide parts, enters the light guide parts through refraction and then is transmitted in the light guide parts, and therefore most of the light consumed in the past is collected and utilized, and the purpose of increasing the brightness is improved; according to the light refraction principle, the reflection curved surfaces of the light guide parts are designed, and therefore the light transmitted inside the light guide parts are refracted constantly, and finally a light-exiting surface with the uniform brightness is formed.
Description
Technical field
The utility model relates to the automobile shift panel, relate in particular to a kind of meet high brightness, brightness evenly, light the automobile shift panel light conducting structure that area is larger.
Background technology
At present, the mode that the light guide structure of automobile shift panel is the light source direct projection is lighted character, during the light source direct projection, its lighting angle often is greater than transmission region, formation light source loss district on the transmission region both sides, cause the brightness of the light on the gear character not high, in the situation that externally light is strong, automobile shift just is difficult to be revealed; The light guide structure of light source direct projection is poor at the brightness uniformity of transmission region on the other hand, generally presents the central area high brightness, and the problem of successively decreasing gradually toward side.
The utility model content
Utility model purpose of the present utility model is in order to solve the problems of the technologies described above, and a kind of automobile shift panel light conducting structure that can meet automobile shift panel high brightness and uniformity requirement backlight is provided.
In order to realize above-mentioned utility model purpose, the technical scheme that the utility model adopts is:
A kind of automobile shift panel light conducting structure, comprise LED light source, light guide and gear character cover, LED light source corresponding to kinds of characters on described gear character cover, and the light of different LED light source is transmitted on gear character cover by light guide;
Between the light incident side of described light guide and light reflection end, be arcuate structure, the formation reflecting curved surface by arcuate structure in light guide inside.
Wherein, the radius of described reflecting curved surface is greater than the twice of light guide thickness.
In order to realize higher luminosity or the illumination effect of multiple color, the light incident side that the utility model is further optimized described light guide is provided with two or more planes of incidence, and described LED light source correspondence is provided with two or more LED light emitting diodes.
In order to reduce the loss of light, the utility model is further optimized, and described LED light emitting diode is close to the plane of incidence of described light guide.
The beneficial effects of the utility model are: 1, solve the intensity loss problem.Utilize refraction and the principle of reflection of light, light is penetrated at the light guide incidence surface and is entered the light guide conducted inside by refraction, so just can Collection and use the light of most of script loss, thereby reach the purpose that increases brightness.2, solve the poor problem of brightness uniformity.Utilize equally the reflection of light principle, the reflecting curved surface of design light guide, make constantly to reflect at the light of the conducted inside of light guide, finally presents a uniform exiting surface of brightness.3, the LED light source of different colours diverse location can be thrown at assigned address.
The accompanying drawing explanation
The structural representation that Fig. 1 is the utility model automobile shift panel light conducting structure.
Wherein:
The 1:LED light source; 2: light guide; 3: gear character cover.
The specific embodiment
By describing technology contents of the present utility model, structural feature in detail, being realized purpose and effect, below in conjunction with embodiment and coordinate accompanying drawing to be explained in detail.
Please generally consult Fig. 1, as shown in the figure, the utility model automobile shift panel light conducting structure, comprise LED light source 1, light guide 2 and gear character cover 3, light guide 2 is arranged between gear character cover 3 and LED light source 1, LED light source 1 corresponding to kinds of characters on described gear character cover 3, the light of different LED light source 1 is transmitted on gear character cover 3 by light guide 2; Described light guide 2 is the arc light guide, between the light incident side of light guide 2 and light reflection end, is arcuate structure, the formation reflecting curved surface by arcuate structure in light guide 2 inside.The utility model utilizes refraction and the principle of reflection of light, and light is penetrated at the light guide incidence surface and entered the light guide conducted inside by refraction, so just can Collection and use the light of most of script loss, thereby reach the purpose that increases brightness.Utilize equally the reflection of light principle, the reflecting curved surface of design light guide, make constantly to reflect at the light of the conducted inside of light guide, finally presents a uniform exiting surface of brightness.
In the present embodiment, the radius of described reflecting curved surface is greater than the twice of light guide thickness, and in this scope, light guide effect is good, and fiber-loss is minimum.In the present embodiment, in order to realize higher luminosity and more various illumination effect, the light incident side that the utility model is further optimized described light guide is provided with two or more planes of incidence, and described LED light source correspondence is provided with two or more LED light emitting diodes.In order to reduce the loss of light, the utility model is further optimized simultaneously, and described LED light emitting diode is close to the plane of incidence of described light guide, and wherein the LED light emitting diode is the paster LED light emitting diode.
The foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in scope of patent protection of the present utility model.
