Abstract
A projection device includes: a housing that includes a base portion and a protruding portion protruding from the base portion; a projection lens that projects image light onto a projection target, is disposed to face the protruding portion, and is mounted on the base portion; a prism that is disposed in the base portion to face an incident-side end part of the projection lens; a plurality of transmission type electro-optical elements that are arranged to face a plurality of side surfaces of the prism, respectively; and a semiconductor light source that is disposed in the protruding portion and generates the image light.
Claims2
A projection device, comprising:
- a housing that includes a base portion and a protruding portion protruding from the base portion;
- a projection lens that projects image light onto a projection target, is disposed to face the protruding portion, and is mounted on the base portion;
- a prism that is disposed in the base portion to face an incident-side end part of the projection lens;
- a plurality of transmission type electro-optical elements that are arranged to face a plurality of side surfaces of the prism, respectively;
- a semiconductor light source that is disposed in the protruding portion and generates the image light;
- and
- a wavelength conversion element that is provided in the base portion and converts a wavelength of light emitted from the semiconductor light source,
- wherein the wavelength conversion element is disposed to be close to a side surface, which is closer to the protruding portion, of two side surfaces of the base portion facing each other.
A projection device, comprising:
- a housing that includes a base portion and a protruding portion protruding from the base portion;
