## Abstract

An illumination apparatus for a vehicle component, especially for a rearview device of a motor vehicle, features at least one illuminant for emitting light and a condenser unit having at least one condenser lens. The condenser unit is adapted to focus the light emitted by the at least one illuminant into an optical path. At least one mask means is provided, which is arranged in the optical path and by means of which an image, symbol, logo and/or legend can be displayed on a projection surface. A lens unit having at least one objective lens, is arranged in the optical path, and at least one reflector unit, is arranged between the condenser unit and the projection surface. The reflector unit is adapted to deflect the optical path, especially essentially transversely or diagonally, to the projection surface, wherein the reflector unit comprises a reflector element which comprises at least one surface section by means of which the light can be deflected relative to the optical path. The surface section of the reflector element is configured as a freeform surface in order to focus the light.

## Claims

### Claim 1

at least one illuminant for emitting light;
a condenser unit having at least one condenser lens, wherein the condenser unit is adapted to focus the light emitted by the at least one illuminant into an optical path;
at least one mask means, which is arranged in the optical path and by means of which an image, symbol, logo and/or legend can be displayed on a projection surface;
a lens unit having at least one objective lens, which is arranged in the optical path and provides a magnification characteristic to the image, symbol, logo and/or legend displayed on the projection surface; and
at least one reflector unit, which is arranged between the condenser unit and the projection surface, wherein the reflector unit is adapted to deflect the optical path, especially essentially transversely or diagonally, to the projection surface, wherein the reflector unit comprises a reflector element which comprises at least one surface section by means of which the light can be deflected relative to the optical path, and wherein the surface section of the reflector element is configured as a freeform surface in order to focus the light, and further wherein the light which is emitted from the at least one illuminant is configured to change direction only upon passing through the reflector unit and does not change direction upon passing through the objective lens.

### Claim 2 (depends on 1)

The illumination apparatus according to claim 1, wherein the at least one reflector unit is adapted to deflect the optical path in a range of 35° to 145°.

### Claim 3 (depends on 1)

The illumination apparatus according to claim 1, wherein the at least one reflector unit is arranged along the optical path of the light from the illuminant up to the projection surface in front of or behind the lens unit.

### Claim 4 (depends on 1)

The illumination apparatus according to claim 1, wherein the mask means is arranged along the optical path of the light from the illuminant to the projection surface between the condenser unit and the lens unit.

### Claim 5 (depends on 1)

The illumination apparatus according to claim 1, wherein the reflector unit comprises the mask means.

### Claim 6 (depends on 1)

The illumination apparatus according to claim 1, wherein the mask means is mechanically and/or electrically alterable or adjustable in order to change the image, symbol, logo and/or the legend that the mask means can display on the projection surface.

### Claim 7 (depends on 1)

The illumination apparatus according to claim 1, wherein the reflector unit comprises a lens means arranged on the reflector element and configured as a separate or separable component in order to focus the light.

### Claim 8 (depends on 7)
