Abstract
An embodiment of this invention regards the production and projection of rainbow colors from sunlight or an alternative light source, and more particularly, the production and projection of a multicolored rainbow patch of light onto a chosen target, such as a ceiling or wall, an object, or any other target. A prism receives a lightstream either directly or by reflection from a mirror. The lightstream enters the prism at a specific angle and is refracted, emerging as a rainbow light. The rainbow light is directed towards the chosen target either directly from the prism or by reflection from a mirror.
Claims17
A rainbow projector comprising:
- a prism having an entry face and an exit face not parallel to the entry face, the prism being without substantially reflective surfaces along a path from the entry face to the exit face;
- receiving means to receive a lightstream at the entry face at an angle of incidence;
- an aimer mirror having an aimer light reflecting surface, the aimer mirror not attached to the prism;
- the prism allowing the lightstream to pass through the prism along the path and the lightstream being dispersed at the entry face and at the exit face to form a rainbow light;
- transmittal means to transmit the rainbow light from the exit face to the aimer mirror;
- and
- aimer adjustment means positioning the aimer mirror such that the aimer light reflecting surface is positionable to receive the rainbow light and reflect the rainbow light in a desired manner.
A rainbow projector system comprising:
- a light source emitting a lightstream;
- a source mirror having a source light reflecting surface;
- a prism having an entry face and an exit face not parallel to the entry face, the prism being without substantially reflective surfaces along a path from the entry face to the exit face;
- an aimer mirror having an aimer light reflecting surface, the aimer mirror not attached to the prism;
- source adjustment means positioning the source mirror such that the source light reflecting surface is positionable to receive the lightstream and reflect the lightstream to the entry face at an angle of incidence;
- the prism allowing the lightstream to pass through the prism along the path and the lightstream being dispersed at the entry face and at the exit face to form a rainbow light;
- transmittal means to transmit the rainbow light from the exit face to the aimer mirror;
- and
- aimer adjustment means positioning the aimer mirror such that the aimer light reflecting surface is positionable to receive the rainbow light and reflect the rainbow light to a target;
- the target being able to display the rainbow light as a rainbow patch.
A method for producing a rainbow light, the method comprising:
- obtaining a lightstream;
- receiving the lightstream at an entry face of a prism having an entry face and the exit face not parallel to the entry face, at an angle of incidence, the prism being without substantially reflective surfaces along a path from the entry face to the exit face;
- passing the lightstream through the prism from the entry face to the exit face, and the lightstream being dispersed at the entry face and at the exit face to form a rainbow light;
- transmitting the rainbow light to an aimer mirror having an aimer light reflecting surface to receive the rainbow light, the aimer mirror not attached to the prism;
- and
- reflecting the rainbow light from the aimer light reflecting surface in a desired manner.
