Vehicle lamp

1. A vehicle lamp, comprising:

at least one semiconductor light source;

at least one light emission body; and

a concentrator arranged between the at least one semiconductor light source and the respective light emission body;

wherein a larger light entrance area of the concentrator is separated from the at least one semiconductor light source by a gap;

wherein the concentrator at its smaller light exit area transitions into the light emission body; and

wherein the light emission body is covered with a plurality of partly transmissive layers having different transmittances;

wherein a first transmittance of a partly transmissive layer closest to the light exit area of the concentrator, a second transmittance of a partly transmissive layer further away from the light exit area, and a third transmittance of a partly transmissive layer even further away from the light exit area become progressively greater.

2. The vehicle lamp of claim 1 ,

wherein the partly transmissive layers exhibit a higher transmittance with greater distance from the light exit area of the concentrator.

3. The vehicle lamp of claim 1 ,

wherein at least one partly transmissive layer consists of alternating plies having higher and lower refractive indices or is a metallic layer.

4. The vehicle lamp of claim 1 ,

wherein the light emission body is a scattering body.

5. The vehicle lamp of claim 1 ,

wherein a side wall of the concentrator is covered with a reflective layer.

6. The vehicle lamp of claim 1 ,

wherein a light guiding adapter is disposed upstream of the concentrator, which light guiding adapter, at its light entrance area, is separated from the at least one semiconductor light source by the gap and, at its light exit area, transitions into the light entrance area of the concentrator.

7. The vehicle lamp of claim 5 ,

wherein the adapter together with the concentrator and together with the light emission body forms an integral, self-supporting body.

8. The vehicle lamp of claim 5 ,

wherein the at least one semiconductor light source is introduced in a depression of a diffusely reflective frame, into which depression the adapter is also inserted.

9. The vehicle lamp of claim 6 ,

wherein the adapter has an angular light incidence area and a round light exit area.

10. The vehicle lamp of claim 1 ,

wherein the light emission body has a higher refractive index than the concentrator.

11. The vehicle lamp of claim 1 ,

wherein at least one of a refractive index of the concentrator or of the adapter is greater than a square root of a ratio between a light source area and a light entrance area of the light emission body.

12. The vehicle lamp of claim 11 ,

wherein at least one of a refractive index of the concentrator or of the adapter is greater than 1.7.

13. The vehicle lamp of claim 1 ,

wherein the concentrator is or comprises a CPC-like concentrator.

14. The vehicle lamp of claim 13 ,

wherein the concentrator is or comprises an angle transformer.

15. The vehicle lamp of claim 1 ,

wherein the semiconductor light sources are arranged in a 2×2 matrix arrangement.

16. The vehicle lamp of claim 1 , wherein each partly transmissive layer of the plurality of partly transmissive layers coat the light emission body in a ring-shaped fashion.

17. The vehicle lamp of claim 16 , wherein the ring-shaped plurality of partly transmissive layers are arranged in series.

18. The vehicle lamp of claim 16 , wherein a first partly transmissive layer has a first transmittance (Ta), a second partly transmissive layer has a second transmittance (Tb), a third partly transmissive layer has a third transmittance (Tc), until an ‘X’ partly transmissive layer has an ‘x’ transmittance (Tx), such that Ta<Tb<Tc . . . <Tx.
