1. A light-emitting device, comprising:
- a light source configured to emit a first light at a first high temperature;
a wavelength conversion material, arranged on the light source, configured to generate a second light in response to an irradiation of the first light, and reach a second high temperature higher than the first high temperature under the irradiation of the first light; and
an optical element separated from the light source by a distance greater than zero, and arranged between the light source and the wavelength conversion material,wherein the wavelength conversion material is unitary, andwherein the optical element has a width larger than that of the light source.
