LIGHT-EMITTING DEVICE

摘要

An embodiment of the present invention discloses a light-emitting device. The light-emitting device includes a light source configured to emit a first light at a first high temperature; and an optical element, distant from 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.

主权项

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 optical element has a width larger than that of the light source.
