Japanese Patent JP6588701
Kind Code:
B2
Abstract:
Methods and apparatus are provided for producing mixed light in a direct-view luminaire. The luminaire includes a plurality of light sources (132) that, in combination, are configured to generate a plurality of different colors of light, a first light mixing chamber (110) and at least one second light mixing chamber (120) in light communication with the first mixing chamber through at least one opening (134). At least one directly viewable light exit surface (112) is coupled to the first light mixing chamber. The light sources are contained in the second light mixing chamber(s), which is configured to prevent light emitted from the light sources from directly impinging on the light exit surface(s). The first light mixing chamber and the light exit surface(s) are configured to mix the light emitted from the light sources such that all light exiting the light exit surface(s) is substantially uniform in brightness and color.
