Abstract
Embodiments provide a light-emitting apparatus including at least one light source, a wavelength converter configured to convert a wavelength of light emitted from the light source, a reflector configured to reflect the light having the wavelength converted in the wavelength converter and light having an unconverted wavelength, and a refractive member disposed in a light passage space between the reflector and the wavelength converter, the refractive member being configured to emit the reflected light.
Claims20
A light-emitting apparatus comprising:
- at least one light source;
- a wavelength converter configured to convert a wavelength of light emitted from the light source;
- a reflector configured to reflect the light having the wavelength converted in the wavelength converter and light having an unconverted wavelength;
- a refractive member disposed in a light passage space between the reflector and the wavelength converter, the refractive member being configured to emit the reflected light;
- and
- a base substrate disposed to be opposite to the reflector,
- wherein the refractive member includes:
- a rounded first surface disposed to face the reflector;
- a second surface having a first portion disposed to face the wavelength converter, and a second portion excluding the first portion;
- and
- a third surface for emission of the reflected light,
- wherein the base substrate includes first and second areas adjacent to each other,
- wherein the first area corresponds to an area excluding the second area, or the first area corresponds to an area facing the second portion of the second surface of the refractive member, and
- wherein the second area corresponds to an area, in which the wavelength converter is disposed.
