Abstract

An indirect lighting apparatus includes a light-emitting device, a reflector disposed above the light-emitting device, and a wavelength conversion layer disposed on a surface of the reflector facing the light-emitting device and spaced apart from the light-emitting device. The wavelength conversion layer includes phosphors configured to change the wavelength of light emitted from the light-emitting device. The reflector is configured to reflect light emitted from the wavelength conversion layer, back towards the wavelength conversion layer.
