Abstract

A planar lighting mirror in which nano-patterns are formed on an entirety or at a specific local area of a mirror surface of a mirror glass and a light source is disposed around the nano-patterns to be used like a mirror in normal operation. In particular, when the light source is activated, the entirety or the specific local area of the mirror surface with the nano-patterns formed thereon planarly emits light from the light source which flows into the side of the mirror glass so as not to deteriorate a mirrors reflective functions.

Claims

1. A planar lighting mirror for an automobile side mirror, comprising:

a planar lighting glass with nano-patterns formed directly on an entire surface or a specific local surface of the planar lighting glass;

a light source disposed on a side of the planar lighting glass to irradiate light onto the side of the planar lighting glass; and

a metal coated layer coated on one surface of the planar lighting glass to reflect the light from the light source to a non-coating surface of the planar lighting glass.

2. The planar lighting mirror of claim 1, wherein the nano-patterns have a smaller size than a wavelength of visible-rays.

3. The planar lighting mirror of claim 1, wherein the nano-patterns are directly formed on the surface of the planar lighting glass through masking and etching processes or indirectly formed by coating the glass surface with a film having nano-patterns.

4. The planar lighting mirror of claim 1, wherein when the light of the light source is not being irradiated onto the side of the planar lighting glass, visible-rays transmittance is 85% to 99%.

5. The planar lighting mirror of claim 1, wherein the light source is selected from a group consisting of a light emitting diode (LED), a laser diode (LD), and a cold cathode fluorescent lamp (CCFL).

6. The planar lighting mirror of claim 1, wherein the light source is a plurality of light sources emitting different colors in order to show various emission colors disposed on the side of the planar lighting glass.

7. The planar lighting mirror of claim 1, wherein the metal coated layer is coated on one surface with the nano-patterns or the other surface without the nano-patterns of the planar lighting glass.

9. The planar lighting mirror of claim 1, wherein the nano-patterns are an indicator for a blind spot detection (BSD) system of the automobile side mirror when the light source irradiates light onto the side of the planar lighting glass.

8. An automobile side mirror system comprising:

a planar lighting mirror having;

a planar lighting glass with nano-patterns formed on an entire surface or a specific local surface,

a light source disposed on a side of the planar lighting glass to irradiate light onto the side of the planar lighting glass, and

a metal coated layer coated on one surface of the planar lighting glass to reflect the light from the light source to a non-coating surface of the planar lighting glass, wherein the planar lighting mirror is mounted inside and outside an automobile side mirror;

an indicator for a blind spot detection (BSD) system nano patterns formed in the planar lighting mirror.
