Abstract: Arrangements of solid state light sources for color-mixing, and light sources including the same, are provided. A substrate has and a plurality of different color LED chips coupled thereto. The emitted light is mixed to produce a white light output. The LED chips are arranged on the substrate in a manner that improves color-mixing, for example, by forming LED sets including one or more LED chips of different colors, by skewing the LED chips, and/or by forming a non-rectangular array or a circular array of LED sets and/or chips. The color-mixing LED arrangement may be used in a lamp or other light source together with collimating optics to collimate and further mix the color-mixed light output from the LED arrangement. The color-mixing LED arrangement may be provided as a single package with multiple LED chips or as multiple packages of one or more LED chips.
