SOLID-STATE LIGHT SOURCE
First Claim
1. A light source module, comprising:
- one or more light emitters of a first color forming a first color group;
one or more light emitters of a second color forming a second color group, the one or more light emitters of the second color group connected in series to the one or more light emitters of the first color group;
a second color group adjustment circuit connected in parallel to the one or more light emitters of the second color group, the second color group adjustment circuit configured to adjust color, to adjust intensity of output light, or to adjust color and intensity of output light of the second color group; and
a current source connected in series to solid-state color emitters of the first and the second color groups.

18. A method for producing a light of a particular color at the output of a light source module, comprising:
-
providing a current flow through a series of light emitters, wherein the series of light emitters comprises one or more light emitters of a first color and one or more light emitters of a second color; and adjusting current flow through the light emitters of the second color such that a combined light output of all light emitters of the first color and the second color has a particular color characteristic. - View Dependent Claims (19, 20, 21, 22)
