Abstract

The invention relates to a skin treatment device, a lamp for use in such a skin treatment device, and its use. The skin treatment device according to the invention uses a combination of tanning-effective and/or anti-acne effective amounts of blue light in the spectral range from 400-440 nm in addition to the UV-light known in the art. An important advantage is that a lower UV dose can be used, leading to lower health risks, while the exposure times can be kept within acceptable limits, without compromising the skin treatment result.

First claim

The invention claimed is:

1. Lamp suitable for use in a skin treatment device comprising radiation-emitting means, said means comprising a light-emitting material capable of emitting a tanning-effective and/or anti-acne effective amount of UV-light and a tanning-effective and/or anti-acne effective amount of blue light;
wherein the lamp is adapted to emit UV-light with a erythemal weighted irradiance between 0.1 and 0.3 W/m 2 for both UV-A (320-400 nm) and UV-B (260-320 nm), and wherein the lamp is adapted to emit blue light in the spectral range from 400 to 440 TIM with a power density between 200 and 500 W/m 2 ;
wherein the light-emitting material comprises at least one UV-emitting component and at least one blue-emitting component; and,
wherein the light-emitting material comprises (FeCo)I 2 TlI as the UV-emitting component.

2. Skin treatment device according to, claim 1 , wherein the radiation-emitting means comprises a lamp which comprises a light-emitting material capable of emitting both a tanning-effective and/or anti-acne effective amount of UV-light and a tanning-effective and/or anti-acne effective amount of blue light.

3. Skin treatment device according to claim 1 , wherein the radiation-emitting means further comprise LEI) lights for generating red light.

4. Lamp according to claim 1 wherein the light-emitting material comprises at least one component selected from the group consisting of: GaI 3 , AlI 3 and InI 3 as the blue-emitting component.

5. Lamp according to claim 4 , wherein the light-emitting material comprises GaI 3 and AlI 3 .
