Various system embodiments comprise a substrate of high thermal conductivity, a solid state light emitting device, an electric circuit, and an electric dielectric. The device has a die and a connection point to the die with a low thermal resistance. The connection point is in contact with the substrate. The electric circuit is electrically connected to the light emitting device, and separated from the substrate by the electrical dielectric. Various system embodiments comprise at least four color sources; and a controller configured to calculate a solution to form a target color using the color sources when the target is outside of a gamut formed by the color sources. The controller is configured to find an equivalent target color with reduced saturation.

Solid state light fixture with enhanced thermal cooling and color mixing

A projection device embodiment comprises a light source system, a gate with a cross sectional gate area, and projection optics. The light source system includes a solid-state light source configured to provide light, and light source optics. The light source optics are configured to distribute light from the solid-state light source across the gate area of the gate. The gate is configured to be used to produce an object to be imaged by the projection device. The projection optics is configured to project an image of the object.

Projection device for architectural and entertainment lighting

Various optical system embodiments produce a narrow beam of focused or unfocused light using a compound parabolic concentrator, lens system, and high flux density solid-state light source. Various system embodiments include a solid state light source configured to emit light, and a compound parabolic concentrator having a smaller opening and a larger opening opposite the smaller opening, wherein the light source and the concentrator are operationally positioned with respect to each other for light from the light source to enter the smaller opening of the concentrator and exit the larger opening of the concentrator as a narrower beam of light. Some embodiments include an imaging stage operationally positioned with respect to the concentrator to receive the narrower beam of light at an image plane and relay an image plane to a far field target.
