Abstract
A projector includes a light source to emit light, a design plate including a design for projecting, a first lens part including a condenser lens to condense light emitted from the light source and sends to the design plate, and a second lens part including a projection lens to project the design of the design plate. The first lens part and the second lens part sandwich and fix the design plate to seal the design plate inside.
Claims9
A projector, comprising:
- a light source to emit light;
- a design plate comprising a design for projecting;
- a first lens part comprising a condenser lens to condense light emitted from the light source and sends to the design plate;
- and
- a second lens part comprising a projection lens to project the design of the design plate,
- wherein the first lens part and the second lens part sandwich and fix the design plate to seal the design plate inside.
