Abstract

Provided is an automotive lamp which forms a stereoscopic image by transmitting light of a light source through a lenticular lens. The automotive lamp includes: a light source; and a light pattern forming component which forms a plurality of light patterns by transmitting light emitted from the light source, wherein the light pattern forming component enables a light pattern of a different image to be observed based on a viewing angle, and light patterns of different images provide a continuous motion as the viewing angle changes sequentially in a specific direction.

First claim

What is claimed is:

1. An automotive lamp, comprising:
a light source; and
a light pattern forming component configured to form a plurality of light patterns by transmitting light emitted from the light source,
wherein the light pattern forming component enables a light pattern of a different image to be observed based on a viewing angle, and light patterns of different images provide a continuous motion as the viewing angle sequentially changes in a specific direction, and
wherein different images are separated into an image segment, the image segment that is passed through a lenticular lens is connected to form a specific light pattern, and the image segment is dispersed based on a location on a rear surface of a diffusion lens.

2. The automotive lamp of claim 1 , wherein the light pattern forming component includes,
an image layer having the different images,
wherein the lenticular lens is configured to form a light pattern of a specific image among the different images at a specific viewing angle by dispersing light that transmits through the image layer.

3. The automotive lamp of claim 2 , wherein each of the different images are separated into a plurality of image segments, and the plurality of image segments are included in the image layer to correspond to different diffusion lenses which form the lenticular lens.

4. The automotive lamp of claim 2 , wherein each of the different images is configured to determine a transmission pattern of the light.

5. The automotive lamp of claim 4 , wherein each of the different images includes a high luminosity region and a low luminosity region based on the transmission pattern of the light.

6. The automotive lamp of claim 5 , wherein the high luminosity region and the low luminosity region are determined based on a thickness of the image layer, whether the image layer is coated with paint for forming the images, and the degree to which the image layer is coated with the paint.

7. The automotive lamp of claim 5 , wherein the different images are configured to provide the continuous motion through a sequential adjustment in the size of each of the high luminosity region and the low luminosity region.

8. The automotive lamp of claim 5 , wherein the different images are configured to provide the continuous motion through a random adjustment in at least one of the area and location of each of the high luminosity region and the low luminosity region.

9. The automotive lamp of claim 5 , wherein the different images are configured to provide the continuous motion as the high luminosity region sequentially changes to the low luminosity region or as the low luminosity region sequentially changes to the high luminosity region.

10. The automotive lamp of claim 5 , wherein the different images are configured to provide the continuous motion through a sequential change in at least one of the area and location of each of the high luminosity region and the low luminosity region.

11. The automotive lamp of claim 4 , wherein each of the different images includes a plurality of regions in which a first luminosity of several regions is different from a second luminosity of other regions, and determined as a difference of luminosity between each region.

12. The automotive lamp of claim 4 , wherein each of the different images includes a plurality of regions in which luminosity of several regions is different from other regions and is determined as a boundary between a high luminosity region and a low luminosity region.
