Abstract
Provided is a lighting device for a vehicle including a light source configured to emit light, a shield layer configured to be positioned in front of the light source, and have a shield portion that shields light emitted from the light source and a first pattern portion through which the light emitted from the light source is transmitted, and a pattern layer configured to be positioned in front of the shield layer, include a light-transmissive material, and have a second pattern portion.
Claims15
A lighting device for a vehicle, comprising:
- a light source configured to emit light;
- a shield layer positioned in front of the light source and having a first geometric pattern, wherein the shield layer includes a plurality of first boundary lines defining a first geometric shape arranged repeatedly to form the first geometric pattern, and is configured to shield the light emitted from the light source except for the light emitted to the plurality of first boundary lines;
- and
- an optical pattern film positioned in front of and separate from the shield layer, including a light-transmissive material, and having second and third geometric patterns superposing each other to create a three-dimensional (3D) image when the light emitted from the light source transmitted to the optical pattern through the plurality of first boundary lines of the shield layer,
- wherein the optical pattern film includes:
- a plurality of second boundary lines defining a second geometric shape arranged repeatedly to form the second geometric pattern, wherein the second geometric shape is different from the first geometric shape, and the plurality of second boundary lines is arranged offset from the plurality of the first boundary lines of the shield layer to avoid overlapping the plurality of the first boundary lines;
- and
- a plurality of third boundary lines defining a third geometric shape arranged repeatedly to form a third geometric pattern, wherein the third geometric shape is identical to the first geometric shape, and the plurality of third boundary lines is aligned with the plurality of first boundary lines of the shield layer to overlap the plurality of the first boundary lines.
