## Abstract

The present disclosure relates to an IPL light guiding device. The IPL light guiding device include handle for manual operation, a light source equipped inside a reflective casing, and an installment section formed below the light source, lens that is detachably coupled to the installment section, the lens forming three-dimensional body allowing light emitted from the light source to pass through and irradiate the bottom surface, bottom surface of the body including concentrating unit irradiated with light, and reflecting unit formed between the concentrating unit, which reflect light toward the concentrating unit, light emitted from the light source concentrated and irradiated onto the concentrating unit.

## Claims

### Claim 1

An Intense Pulse Light (IPL) light guiding device comprising:
a handle for manual operation, a light source equipped inside a reflective casing, and an installment section formed below the light source;
a lens that is detachably coupled to the installment section;
the lens forming a three-dimensional body allowing light emitted from the light source to pass through and irradiate the bottom surface of the body;
wherein the bottom surface of the body includes concentrating units irradiated with the light, and reflecting units formed between the concentrating units, which reflect light toward the concentrating units;
wherein the light emitted from the light source is concentrated and irradiated onto the concentrating units.

### Claim 2 (depends on 1)

The IPL light guiding device of claim 1, wherein:
the bottom surface of the body is flat, the surface comprising grooves forming a specific pattern which form the reflecting units, while the non-grooved portions form the concentrating units;
wherein the internal walls of the grooves are sloped, reflecting light toward the concentrating units from the boundary surface between the body and the internal area of the reflecting units.

### Claim 3 (depends on 2)

The IPL light guiding device of claim 2, wherein:
the reflecting unit is formed by grooves engraved in a grid pattern.

### Claim 4 (depends on 3)

The IPL light guiding device of claim 3, wherein:
the grooves have a triangular cross section.

### Claim 5 (depends on 4)

The IPL light guiding device of claim 4, wherein:
the triangular cross-section is a isosceles triangle.

### Claim 6 (depends on 3)

The IPL light guiding device of claim 3, wherein:
the grooves have a circular cross section.

### Claim 7 (depends on 3)

The IPL light guiding device of claim 3, wherein:
the grooves have a rectangular cross section.
