## Abstract

A light reflecting device comprises: two juxtaposed elongate sidewalls having inwardly curved inner surfaces facing each other; two opposite side panels, the sidewalls interposed and connected between the side panels, the side panel has flat inner surfaces facing each other and being perpendicular to a lengthwise direction of the sidewalls; and an elongate bottom wall interconnected between the sidewalls and the side panels, the bottom wall has an elongated outwardly curved inner surface interconnected between the inwardly curved inner surfaces.

## Claims

### Claim 1

A light reflecting device comprising:
two juxtaposed elongate sidewalls having inwardly curved inner surfaces facing each other;
two opposite side panels; the sidewalls interposed and connected between the side panels, the side panels having flat inner surfaces facing each other and being perpendicular to a lengthwise direction of the sidewalls; and
an elongate bottom wall interconnected between the sidewalls and the side panels, the bottom wall having an elongated outwardly curved inner surface interconnected between the inwardly curved inner surfaces.

### Claim 2 (depends on 1)

The light reflecting device of claim 1, wherein a radius of an arc defined by each inwardly curved inner surface is greater than a radius of an arc defined by the outwardly curved inner surface.

### Claim 3 (depends on 1)

The light reflecting device of claim 1, further comprising a reflecting layer formed on the outwardly curved inner surface, the flat inner surfaces and the inwardly curved inner surfaces.

### Claim 4 (depends on 1)

The light reflecting device of claim 1, wherein the reflecting layer is made of metal.

### Claim 5 (depends on 1)

The light reflecting device of claim 1, wherein the metal is selected from the group consisting of gold, silver, copper, aluminum and any combination thereof.

### Claim 6

A light curing device, comprising:
a light reflecting device comprising:
two juxtaposed elongate sidewalls having inwardly curved inner surfaces facing each other;
two opposite side panels; the sidewalls interposed and connected between the side panels, the side panel having flat inner surfaces facing each other and being perpendicular to a lengthwise direction of the sidewalls; and
an elongate bottom wall interconnected between the sidewalls and the side panels, the bottom wall having an elongated outwardly curved inner surface interconnected between the inwardly curved inner surfaces; and
an ultraviolet light bulb received in the light reflecting device and mounted on the bottom wall.

### Claim 7 (depends on 6)

The light curing device of claim 6, wherein a distance between the ultraviolet light bulb and the outwardly curved inner surface is less than about 5 mm.

### Claim 8 (depends on 6)

The light curing device of claim 6, wherein a distance between the ultraviolet light bulb and the outwardly curved inner surface is equal to about 5 mm.

### Claim 9 (depends on 6)
