Abstract

Systems, apparatuses, and methods for light source modules for adaptive color adjustments are described. A light source module includes a housing having a window, an emitter array, an accompanying emitter, and a lens. The emitter array includes a plurality of emitters, each emitter configured to emit light having a first color through the window. The accompanying emitter is configured to emit light having a second color through the window. The lens includes a first portion and a second portion. The first portion is positioned between the emitter array and the window, and configured to image the emitter array onto a field of illumination. The second portion is positioned between the accompanying emitter and the window, and the lens configured to direct the light emitted by the accompanying emitter to fill the field of illumination.

First claim

1 . A light source module, comprising:
a housing comprising a window; an emitter array comprising a plurality of emitters, each of which is configured to emit light having a first color through the window; an accompanying emitter configured to emit light having a second color through the window; and a lens comprising:
a first portion positioned between the emitter array and the window, wherein the first portion is configured to image the emitter array onto a field of illumination; and
a second portion positioned between the accompanying emitter and the window, wherein the lens is configured to direct the light emitted by the accompanying emitter to fill the field of illumination.

2 . The light source module of claim 1 , wherein each emitter of the plurality of emitters is operable to illuminate a different portion of the field of illumination.

3 . The light source module of claim 1 , wherein the plurality of emitters comprises:
at least one central emitter that fills a first portion of the field of illumination; and a plurality of peripheral emitters that surround the at least one central emitter and that fills a second portion of the field of illumination.

4 . The light source module of claim 1 , wherein:
the emitter array has a first light-emitting surface; and the accompanying emitter has a second light-emitting surface oriented in a same direction as the first light-emitting surface.

5 . The light source module of claim 1 , further comprising:
the emitter array has a first light-emitting surface; and the accompanying emitter has a second light-emitting surface oriented to face away from the emitter array.

6 . The light source module of claim 1 , further comprising:
the emitter array has a first light-emitting surface; and the accompanying emitter has a second light-emitting surface oriented to face toward the emitter array.

7 - 20 . (canceled)

21 . A light source module, comprising:
a housing comprising a window; an emitter array comprising a plurality of emitters, each of which is configured to emit light having a first color through the window; and an accompanying emitter configured to emit light having a second color through the window, wherein: a rear surface of the window defines a set of optical structures positioned at least partially over the emitter array.

22 . The light source module of claim 21 , wherein:
the set of optical structures comprises a lens positioned at least partially over the emitter array.

23 . The light source module of claim 22 , wherein:
the set of optical structures comprises a set of Fresnel rings surrounding the lens.

24 . The light source module of claim 23 , wherein:
the set of optical structures comprises a set of concentric prisms surrounding the set of Fresnel rings.

25 . The light source module of claim 21 , wherein:
the rear surface of the window defines a light guide positioned at least partially over the accompanying emitter and at least partially surrounding the set of optical structures.

26 . The light source module of claim 25 , wherein:
the light guide encircles the set of optical structures.

27 . The light source module of claim 25 , wherein:
the accompanying emitter is a first accompanying emitter; the light source module further comprises a second accompanying emitter configured to emit light through the window; and the light guide is positioned at least partially over the second accompanying emitter.

28 . The light source module of claim 25 , comprising:
a light sensor, wherein the light guide is positioned at least partially over the light sensor.

29 . The light source module of claim 25 , wherein:
a bottom surface of the light guide is configured as a prismatic surface having a plurality of concentric prisms.

30 . The light source module of claim 21 , comprising:
an optical component positioned at least partially between the accompanying emitter and the window, wherein the optical component is positioned at least partially over the accompanying emitter.

31 . The light source module of claim 30 , wherein:
the accompanying emitter is a first accompanying emitter; the light source module further comprises a second accompanying emitter configured to emit light through the window; and the optical component is positioned at least partially over the second accompanying emitter.

32 . The light source module of claim 30 , wherein:
the optical component comprises an annular light guide.

33 . The light source module of claim 30 , wherein:
wherein the optical component defines a lens positioned at least partially over the accompanying emitter.

34 . The light source module of claim 30 , wherein:
the accompanying emitter is a first accompanying emitter; the optical component is a first optical component; and the light source module further comprises:
a second accompanying emitter configured to emit light through the window; and

a second optical component positioned at least partially over the second accompanying emitter
