Abstract

The invention relates to an LED module (1) for a luminaire (2) comprising at least one LED carrier (3) and a plurality of LEDs (4) (light-emitting diodes) arranged on this LED carrier. In particular, intensities of different-colored LEDs (4) are selected to emit a total light emission spectrum (6) being composed of individual light emission spectra (5) of each LED. The invention further relates to a luminaire (2) comprising a luminaire housing (10), at least one LED module (1) arranged as light source (13) in the luminaire housing (10), a light emergence opening (11) formed in the luminaire housing (10), and a glare-limiting device (12) assigned in particular to the light emergence opening (11), as well as to a method for influencing a light spectrum of a light source (13).

Claims

1. A light emitting diode (“

LED”

) module (1) for a luminaire (2) comprising at least one LED carrier (3) and a plurality of LEDs (4) arranged on this LED carrier, in particular of a predetermined number and color, which are variable relative to one another with regard to the intensities of their individual light emission spectra to emit a total light emission spectrum (6) being composed of individual light emission spectra (5).

2. The LED module according to claim 1, characterized in that each LED (4) is configured to emit substantially monochromatic radiation.

3. The LED module according to claim 1, characterized in that LEDs having the same monochromatic light radiation are each arranged on a sub-module (7) of the LED module (1).

4. The LED module according to claim 1, characterized in that LEDs having different monochromatic light radiation are each arranged on a sub-module (7) of the LED module (1).

5. The LED module according to claim 1, characterized in that LEDs can be arranged on the LED carrier (3) along at least one row (8) and/or a column (9).

6. The LED module according to claim 1, characterized in that all LEDs can be triggered separately.

7. The LED module according to claim 1, characterized in that white LEDs are assigned to the monochromatic LEDs in order to increase a color rendering index.

8. The LED module according to claim 1, characterized in that the LED modules and/or sub-modules can be arranged in the luminaire to be exchangeable.

9. The LED module according to claim 1, characterized in that the sub-modules (7) can be triggered individually.

10. The LED module according to claim 1, wherein the luminaire (2) comprises a luminaire housing (10), at least one of the LED module (1) is arranged as a light source (13) in the luminaire housing (10), the luminaire housing comprising a light emergence opening (11) formed in the luminaire housing (10), and a glare-limiting device (12) assigned in particular to the light emergence opening (11).

11. The LED module according to claim 10, wherein a total light emission spectrum of the luminaire is substantially free from spectral ranges in which at least one specific species, in particular animal species, has a greater sensitivity as compared to other species.

13. A method for influencing a light spectrum of a light source (13), which light source is formed of a plurality of individual LEDs arranged on an LED module (1) particularly in rows (8) and/or columns (9), wherein individual emission spectra of the individual LEDs, in particular if the number and the color of the individual LEDs are predetermined, are superimposed with a variable intensity to one total light emission spectrum as the light spectrum of the light source.

14. The method according to claim 13, characterized by simultaneously and separately triggering all individual LEDs.

15. The method according to claim 13, characterized by individually triggering the individual LEDs on a sub-module (7) for selecting the number of individual LEDs of a specific color.
