Abstract

A lighting device may include a light emitting device and a sidewall extending away from the light emitting device. In addition, a thermally conductive housing may be spaced apart from the sidewall, and a cavity may be defined between the sidewall and the thermally conductive housing. In addition, a lens may be spaced apart from the light emitting device with the sidewall extending away from the light emitting device to the lens to define a mixing chamber adjacent the light emitting device. Moreover, the thermally conductive housing may be outside the mixing chamber, and the sidewall may be reflective.
