Background

As LEDs are applied to vehicle lamps more and more frequently, the requirements of the whole vehicle factory on the shape and lighting effect of the vehicle lamps are more and more novel. Many car lights are more rigorous to the requirement of space for satisfying the figurative flexibility, need optical system compacter, integrate more. The optical system of the lighting effect of the existing novel multidirectional light-emitting generally adopts a mode of a multi-light-source group, so that the cost is increased, and the requirement on the space is higher.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a car light optical system of multidirectional light-emitting uses single light source group not only can realize the effect of lighting of a plurality of directions, can also have certain additional action to the regulation requirement, very big space and cost of having saved.

The utility model provides a novel optical system for car light of multidirectional light-emitting, includes light source system, thick wall, light source system sets up standard spotlight ware including the PCB board of installing LED above the LED, set up total reflection optical surface, optics decorative pattern face and side light-emitting surface on the thick wall, on standard spotlight ware focus was arranged in to LED, the center department of standard spotlight ware rear distance thick wall rear surface 3mm department.

The included angle between the total reflection optical surface and the vertical surface is 5-45 degrees; the angle between the side light-emitting surface and the vertical surface is 10-90 degrees.

The total reflection optical surface comprises but is not limited to a smooth surface, a light guide tooth, a spherical pit and a prismatic pit total reflection structure; the side light-emitting surface comprises but is not limited to a smooth surface, a frosted surface, a horizontal stripe pattern, a vertical stripe pattern and a fish eye pattern.

The light source system includes, but is not limited to, a condenser system, a light guide system, and an LED direct lighting system, which enable the light source to emit light perpendicularly in a forward direction.

The light emitted by the LED of the optical system of the utility model is collimated by the standard condenser and then enters the rear surface of the rectangular condenser to be guided into the thick wall with a certain optical structure, and part of the light is directly emitted from the positive pattern surface to form the lighting of the main light-emitting pattern; and the other part of light is totally reflected by the total reflection surface on the thick-wall side, so that the light is totally reflected to the light outlet surface on the thick-wall side to be emitted, and the light outlet lighting of the second part is formed. Therefore, a lighting effect of multi-directional light emitting can be formed through the single light source group, and light is supplemented to a certain area required by regulations. The utility model discloses a single spotlight ware optical system realizes a plurality of rectangle stripes and lights the effect to there is positive influence to the regulation requirement. Greatly saves the cost and the space and provides greater feasibility for the modeling design.

Detailed Description

In order to make the method means, technical features, achievement effect and application scope of the present invention easy to understand, the present invention will be further explained below.

The prior art thick wall has a normal regular circular shape (as shown in fig. 2) after the thick wall (as shown in fig. 1) is lighted, and no light rays in other specific states exist.

As shown in fig. 3-6, the utility model discloses an optical system includes light source system 1, thick wall 2, light source system 1 is including installing the PCB board 3 of LED4, sets up standard spotlight ware 5 above the LED4, set up total reflection optical surface 7, optics decorative pattern face 6 and side play plain noodles 8 on the thick wall 2, on standard spotlight ware 5 focuses was arranged in to LED, the center department of standard spotlight ware 5 rear distance thick wall 2 rear surface 3mm department.

The utility model discloses an optical system is being determined for 15 through the angle with total reflection face 7, the angle of side play plain noodles 8 is determined for 30 backs, and collimating light has passed through under total reflection face 7 and the influence of side play plain noodles 8, has arrived outside 30 to 40 within ranges (as shown in fig. 7) with partly light total reflection, complements the regulation of this part. Similarly, after the angle of the total reflection surface 7 is set to 30 ° and the angle of the side light exit surface 8 is set to 60 °, the total reflection light reaches the range of 60 ° to 70 ° outside (as shown in fig. 8), and the regulations of the part are complemented.

Light emitted by the LED is collimated by a standard condenser and then is emitted into the rear surface of a rectangular condenser to be guided into a thick wall with a certain optical structure. Wherein, part of the light is directly emitted from the positive pattern surface to form the lightening of the main light emitting pattern; and the other part of light is totally reflected through the optical structure on the side with the thick wall, so that the light is totally reflected to the light-emitting surface with the thick wall to emit light, and the light-emitting lightening of the second part is formed. Thus, the lighting effect of multi-direction light emitting can be formed by the single light source group.

Through a thick wall, the light emitted by the LED is divided into two beams of light rays with different directions, and the two beams of light rays are LED out from two different light emitting surfaces, so that a multi-directional light emitting lighting effect is formed through a single light source system, the regulation requirements are positively influenced, and the cost and the space are greatly saved.

In the above scheme, the angle of the total reflection surface includes 5 ° to 45 °; the angle of the side light-emitting surface includes 10 ° to 90 °.

In the above solution, the optical pattern surface 6 may be designed separately, and may have different design modes according to different regulations.

In the above solution, the optical patterns of the side light emitting surfaces 8 can be designed separately, and different design manners can be provided according to different regulations.
