TLDR
A texture projecting light bulb includes an extended light source located within an integrator as mentioned in this paper, which includes at least one aperture configured to allow light to travel out of the interior of the integrator.Abstract:
A texture projecting light bulb includes an extended light source located within an integrator. The integrator includes at least one aperture configured to allow light to travel out of the interior of the integrator. In various embodiments, the interior of the integrator may be a diffusely reflective surface and the integrator may be configured to produce a uniform light distribution at the aperture to approximate a point source. The integrator may be surrounded by a light bulb enclosure. In various embodiments, the light bulb enclosure may include transparent and opaque regions configured to project a structured pattern of visible and/or infrared light.read more
