Abstract

Provided herein is an indoor emotional lighting apparatus for implementing three-dimensional (3D) pattern for a vehicle, the indoor emotional lighting apparatus including a film portion on which a plurality of fine lenses each having a 3D pattern are arranged, a light source configured to emit light in a plurality of directions, and a light source guide portion configured to guide an optical path of the light source to allow the light emitted from the light source to be directed toward the film portion.

First claim

What is claimed is:

1. A lighting apparatus for implementing three-dimensional (3D) pattern, the lighting apparatus comprising:
a film portion on which a lenticular lens array having a plurality of 3D patterns is arranged, the lenticular lens array includes a plurality of semi-cylindrical lenses;
a light source configured to emit light in a plurality of directions; and
a light source guide portion configured to guide an optical path of the light source to allow the light emitted from the light source to be directed toward the film portion,
wherein the light source guide portion includes:
a housing disposed below the film portion and having a predetermined thickness;
an optical filter disposed on an upper end of the housing and configured to selectively transmit or reflect the light emitted from the light source; and
an optic pattern member disposed in a partial section of a lower portion of the housing to reflect light emitted from the light source including light reflected from the optical filter to the optic pattern member.

2. The lighting apparatus of claim 1 , wherein the light source is disposed on a lateral surface of the housing and emits the light to each of the optical filter and the optic pattern member.

3. The lighting apparatus of claim 1 , wherein the light source is disposed on a lateral surface of the housing, and a deflection angle of the light reflected from the optical filter is determined according to a thickness of the housing.

4. The lighting apparatus of claim 3 , wherein the thickness of the housing allows the deflection angle of the light reflected from the optical filter to be formed as an obtuse angle.

5. The lighting apparatus of claim 1 , wherein the optical filter transmits only light having a wavelength in a predetermined band passing through the optic pattern member to the film portion.

6. The lighting apparatus of claim 1 , wherein the optical filter includes a light source hole provided on a path on which the light, which is emitted from the light source and reflected through the optic pattern member, is directed toward the film portion.

7. The lighting apparatus of claim 6 , wherein the optical filter reflects the light of the light source, which is emitted to a periphery of the light source hole, to the optic pattern member.

8. The lighting apparatus of claim 1 , further comprising an exterior panel disposed to be spaced apart from the film portion and configured to cast the light, which passes through the film portion, to the vehicle interior.

9. The lighting apparatus of claim 8 , wherein the exterior panel is formed of a material which gradationally transmits light from one side to the other side in a length direction.

10. The lighting apparatus of claim 1 , wherein the plurality of semi-cylindrical lenses each having a respective 3D pattern.

11. The lighting apparatus of claim 1 , wherein the optic pattern member includes a side having an incline angle relative to a plane defined by the optical filter.
