Abstract

The invention relates to an illuminating device (10) for illuminating an object, with a lighting element (20) and an inspection element (30), wherein the lighting element (20) comprises at least one first light emitting mean (21), wherein the first light emitting mean (21) is emitting light with a first spectrum (22), wherein the inspection element (30) comprises at least one second light emitting mean (31), wherein the second light emitting mean (31) is emitting light with a second spectrum (32), wherein the second spectrum (32) is essentially separated from the first spectrum (22), with an illuminating mode, operating only the lighting element (20), with an inspection mode, operating the lighting element (20) and the inspection element, and the superposition of the light of the first (21) and the second light emitting mean (31) yields a result light.

Claims

1. An illuminating device for illuminating an object, the illumination device comprising a lighting element and an inspection element,

wherein the lighting element comprises at least one first light emitting means for, emitting light with a first spectrum,

wherein the inspection element comprises at least one second light emitting means for emitting light with a second spectrum,

wherein the second spectrum is essentially separated from the first spectrum, the illumination device operating in either an illuminating mode, operating only the lighting element, or an inspection mode, operating the lighting element and the inspection element such that the superposition of the light of the first and the second light emitting means yields a resultant light.

2. An illuminating device according to claim 1, wherein the resultant light is a white light.

3. An illuminating device according to claim 1, wherein the lighting element comprises at least one third light emitting mean, wherein the third light emitting mean is emitting light with a third spectrum, wherein the third spectrum is essentially separated from the first and the second spectrum.

4. An illuminating device according to claim 3, wherein the first, the second and the third light emitting mean are a LED, an OLED or a gas discharge lamp.

5. An illuminating device according to claim 1, wherein the first spectrum comprises a peak wavelength within the red optical spectrum, the third spectrum comprises a peak wavelength within the blue optical spectrum and the second spectrum comprises a peak wavelength within the green optical spectrum.

6. An illuminating device according to claim 1, wherein the number of the first and the third light emitting means are larger than the number of the second light emitting means.

7. An illuminating device according to claim 1, wherein the illuminating device comprises an analyzing element (40), detecting a light output of the lighting element and adjusting the light output to an output level of the inspection element.

8. An illuminating device according to claim 1, wherein the illuminating device comprises a color sensor element, detecting a reflected spectrum from the object, being illuminated in the illuminating mode or the inspection mode.

9. An illuminating device according to claim 8, wherein the color sensor element communicates with the lighting element, wherein the color sensor element sends a control information to the lighting element for adjusting an output level of the light with the first spectrum and the third spectrum.

11. The illuminating device according to claim 1, wherein the first and third light emitting means are tuned according to the chlorophyll absorption curves.
