Abstract
Among other things, there is a stationary light source, a stationary aperture between the light source and a projection surface, and a device to modulate light from the light source that passes through the aperture and strikes the projection surface to cause a light effect on the projection surface. In some cases, projected motion and/or twinkling effects are produced in a simple, low-cost and durable manner.
Claims18
An apparatus comprising
- a stationary light source,
- a stationary aperture between the light source and a projection surface, and
- a device to modulate light from the light source that passes through the aperture and strikes the projection surface to cause a light effect on the projection surface.
A method comprising
- imposing a time-changing light effect on light projected in a pattern on a surface in a room by
- passing light from a stationary light source through a stationary aperture and
- controlling light passing from the light source to the surface so that pattern on the surface changes over time.
