Document Type and Number:
Japanese Patent JP2021149021
Kind Code:
A
Abstract:
To provide a light emitting device, a light source device, and a projector that are reduced in size.SOLUTION: A light emitting device of the present invention comprises: a first light source that emits first light having a first wavelength range; a wavelength conversion unit that includes a phosphor and converts the first light emitted from the first light source into second light in a second wavelength range different from the first wavelength range; and an angle conversion unit on which the second light emitted from the wavelength conversion unit is incident. The angle conversion unit has a light incident unit on which the second light emitted from the wavelength conversion unit is incident, a light emitting unit that emits the second light, and a reflection unit that reflects the second light toward the light emitting unit, and the light emitting unit includes a first lens array.SELECTED DRAWING: Figure 2
