Abstract:
A lighting apparatus includes a light reflector, a light emitting diode (LED) and a light-changing film. The light reflector has a concave surface. The LED is disposed under the concave surface of the light reflector to provide the concave surface with light. The light-changing film converts a first light generated by the LED into a second light. For example, the light-changing film may be a fluorescent film receiving the first light and emitting the second light with increased wavelength. The LED and the light-changing film are spaced apart from each other to minimize discoloration of the light-changing film.
