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.

First claim

What is claimed is:

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.

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.

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.
