Downsized vehicle projection device having reflective surface and vehicle viewing device
View Patent ↗A vehicle projection device including: a reflector that is provided in a vehicle and is provided with a reflective surface, with the reflective surface reflecting light; an image member that is provided with an image and through which the light reflected by the reflective surface is transmitted; and a lens through which the light that has been transmitted through the image member is transmitted, whereby the image is magnified and projected.
1. A vehicle projection device comprising:
a reflector that is provided in a vehicle and is provided with a reflective surface, with the reflective surface being a paraboloid of revolution and reflecting parallel light;
an image member that is provided with an image and through which the light reflected by the reflective surface is transmitted;
a lens through which the light that has been transmitted through the image member is transmitted, whereby the image is magnified and projected,
a light source,
a shield disposed between the light source and the reflective surface including a passage hole that is provided on a line between the light source and opposing edges of the reflector,
the reflective surface ending before a vertex of the paraboloid, and the passage hole transmitting only light emitted from the light source to the reflective surface.
2. The vehicle projection device according to claim 1 , wherein the reflective surface is a surface on a vertex side of a paraboloid of revolution.
3. The vehicle projection device according to claim 1 , wherein at least one of the image member and the lens is assembled to the reflector.
4. The vehicle projection device according to claim 1 , wherein the image member side of the lens and the side opposite the image member side are convex.
5. The vehicle projection device according to claim 1 , wherein at least one of the reflective surface that reflects the light and the image through which the light is transmitted is changeable.
6. A vehicle viewing device comprising: a viewing component that assists viewing by an occupant of a vehicle; and the vehicle projection device according to claim 1 .
7. The vehicle projection device according to claim 1 , further comprising circuit board, wherein the light source is disposed on the circuit board and wherein the circuit board and the image member are substantially planar and are oriented orthogonally with respect to each other.
