Description

TECHNICAL FIELD [0001] The present invention relates to a three-dimensional tail lamp for a vehicle,

The present invention relates to a stereoscopic tail lamp for a vehicle, and more particularly, to an in-vehicle stereoscopic tail lamp that does not require an inner lens, uses a plurality of light emitting modules having a simple structure composed of one light emitting portion and three pieces of two reflecting surfaces, To an automotive stereoscopic tail lamp that implements an image.

In general, a vehicle lamp is provided with a lens-cut lens disposed in front of a light source so as to improve the appearance of the lamp. However, the appearance of the lamp represented by the lens cut is similar to each other, and there is a limit to appealing to a consumer with a unique aesthetic sense.

In addition, in vehicles that have been sold in recent years, the proportion of LEDs that use incandescent lamps as light sources of lamps is increasing. This is because the LED lamp has an advantage that the power consumption is small and the time required until the LED lamp is turned on is advantageous as compared with the incandescent lamp.

However, since the irradiation angle of the LED lamp is narrow (40 to 60 degrees), there is a drawback that many LEDs must be used when a large light emitting area is required. In addition, the price of LED is expensive now, and it also has a drawback that it costs twice as much as that of an incandescent lamp.

Rear combination lamps and the like are determined by laws and regulations, but high-performance LED lamps capable of satisfying the illuminance with a single LED are being developed.

Nevertheless, the biggest reason that the number of LEDs does not decrease is because they express a sense of quality with a three-dimensional feel to the rear combination lamps. That is, since the irradiation angle is narrow as described above, when using only one LED, the area where the light from the LED touches the lens is small and the area of brightening the lens is small, give. To avoid this, many LEDs are used for design reasons.

To solve these problems, Korean Patent No. 10-0986400 has been proposed.

In the prior art, the light source is disposed at the vertex of the rear side, the side surface is formed in a conical shape or a polygonal pyramid shape, the front side is open in a circular or polygonal shape, and the side surface is provided with a reflecting surface, The shape generating portion formed of at least one of the slit, the hole and the transparent member is provided on the side surface so that the light can be multiply reflected from the reflecting surface to form various geometric shapes, It is possible to reduce the number of LEDs and the cost, to express the geometric shape of the lamp, to make the lamp mechanism to have a long light scattering effect and to produce an excellent design.

However, the prior art has a problem that the structure of the tail lamp is complicated and the productivity is low as compared with the configuration of the light distribution image.
