Abstract
The invention discloses a light guide structure of a car gear panel. The light guide structure comprises an LED light source, a light guide part and a gear character surface cover, wherein different characters on the gear character surface cover correspond to different LED light sources; the light rays of the different LED light sources are transmitted to the gear character surface cover through the light guide part; an arc structure is formed between the light incidence end and the light reflection end of the light guide part; a reflection curve surface is formed in the light guide part through the arc structure. The light guide structure has the benefits as follows: the problems of brightness loss and poor uniformity can be solved by designing the light guide part on the light source; on one hand, the light rays come into the incident surface of the light guide part and are refracted and transmitted in the light guide part by light refraction and reflection principles, so that a great amount of originally lost light rays can be collected and utilized and the purpose of brightness improvement can be achieved; on the other hand, the reflection curve surface of the light guide part is designed by the light reflection principle, so that the light rays transmitted in the light guide part are continuously reflected and a light emergence surface with uniform brightness is finally presented.
Description
Technical field
The present invention relates to the automobile gears panel, relate in particular to a kind of satisfy high brightness, brightness evenly, light the larger automobile gears panel light conducting structure of area.
Background technology
At present, the light guide structure of automobile gears panel is that the mode of light source direct projection is lighted character, during the light source direct projection, its lighting angle is often 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 gears 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 the next door.
Summary of the invention
Goal of the invention of the present invention is in order to solve the problems of the technologies described above, a kind of automobile gears panel light conducting structure that can satisfy automobile gears panel high brightness and uniformity requirement backlight to be provided.
In order to realize the foregoing invention purpose, the technical solution adopted in the present invention is:
A kind of automobile gears panel light conducting structure comprises led light source, light guide and gear character cover, led light source corresponding to kinds of characters on the described gear character cover, and the light of different LED light source is transmitted on the gear character cover by light guide;
Be arcuate structure between the light incident side of described light guide and the light reflection end, by the formation reflecting curved surface of 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 present invention further optimizes 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 present invention further optimizes, and described LED light emitting diode is close to the plane of incidence of described light guide.
Beneficial effect of the present invention is: 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 constantly reflects the light in 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.
Description of drawings
Fig. 1 is the structural representation of automobile gears panel light conducting structure of the present invention.
Wherein:
The 1:LED light source; 2: light guide; 3: gear character cover.
The specific embodiment
