MELANOPIC LAMP

摘要

A lamp having a first light source for producing a light having a spectral distribution, wherein the light is represented by a set of chromaticity coordinates in a chromaticity diagram, and having a second light source for producing a second light having a second spectral distribution, wherein the second light is represented by a second set of coordinates in the chromaticity diagram, the second spectral distribution being different from the first spectral distribution. Furthermore, the lamp has a control unit for controlling the light sources, which control unit is designed so that an intensity of the first light can be changed independently of an intensity of the second light. By changing the intensities of the lights, the weighting of the lights can be changed so that the melanopic effect factor of the light emitted by the lamp is thereby changed without the color temperature of the light changing.

1. A lamp comprising:
a first light source for generating a first light having a first spectral distribution (S1(λ)), wherein the first light is represented by a first color locus in a chromaticity diagram, a second light source for generating a second light having a second spectral distribution (S2(λ)), wherein the second light is represented by a second color locus in the chromaticity diagram, wherein the second spectral distribution (S2(λ)) differs from the first spectral distribution (S1 (λ)), a control unit for driving the first light source and the second light source, which is designed in such a way that an intensity of the first light can be altered independently of an intensity of the second light, wherein the lamp is designed in such a way that the first color locus substantially corresponds to the second color locus.
