Abstract:
A light source is described where the light emitted by a solid-state light emitting device such as an LED is coupled into an optical waveguide such as an optical fiber. A highly reflective coupler (reflector) is disposed around the LED and a segment of the waveguide adjacent the LED. Light emitted from the LED that falls outside of the numerical aperture of the waveguide leaks out of the waveguide, but is reflected back to the waveguide by the reflector. The reflected light is re-reflected or scattered by the LED or the substrate the LED is mounted on, and the re-reflected or scattered light that falls within the numerical aperture of the waveguide is coupled into the waveguide. As a result, light coupling efficiency is increased and the output brightness of the light at the other end of the fiber is enhanced.
Abstract:
A multicolor illumination device using an excitation light source and a multi-segmented moving plate with wavelength conversion materials (e.g. phosphors). The exciting light source is a light emitting diode or a laser diode emitting in the UV and/or blue region. The wavelength conversion materials absorb the excitation light and emit longer wavelength light. Each segment of the moving plate contains a different wavelength conversion material or no wavelength conversion material. The plate is supported to move so that different segments are exposed to the excitation light at different times. The plate may be a wheel or rectangular in shape and rotates or oscillates linearly. When the plate moves, light of different colors is generated sequentially in time by the different wavelength conversion materials in different segments of the plate. The multicolor illumination device may be used in a projector system having a microdisplay imager for image display.
Abstract:
An illumination devices using excitation light and a wavelength conversion material to generated converted light for illumination, where the wavelength conversion material is excited by multiple excitation lights from both sides to achieve increased brightness. The excitation lights incident on the two sides of the wavelength conversion material may have the same color or different colors. Light separation structures are provided on both sides of the wavelength conversion material to separate the excitation light and the converted light. Light separation may be based on color difference or etendue difference of the excitation light and converted light. In one particular example, wavelength conversion material is formed on a surface of an LED which acts as the first excitation light source, and a second excitation light is delivered through a light separation structure onto the other side of the wavelength conversion material.
Abstract:
A light source device includes a LED light source or wavelength conversion material having a near Lambertian light emitting surface. The light source device includes a light recycling system to reflect small-angle lights (lights closer to the normal direction of the light emitting surface) back to the light source, and a collection system for collecting and outputting large-angle lights (lights farther away from the normal direction). The lights reflected by the light recycling system is scattered by the emitting surface in all directions, where the large-angle scattered lights are collected by the light collection system and the small-angle scattered light is reflected by the light recycling system again. A second excitation light source without wavelength conversion material or a second light source with its own wavelength conversion material may be provided, and the second light is directed to the light emitting surface by appropriate optical components.
Abstract:
A brightness maintaining low loss fiber delivering light system includes solid-state light emitting device, such as but not limited to LED; mounting base assembly for the light emitting device; a low loss light collecting assembly, structure integration assembly; optical waveguide such as fiber; and a fiber combiner in the system with multiple light emitting devices. The light emitting device, light collecting assembly and fiber are bonded directly to each other or by optically index matching transparent material. The etendue of the light emitting device and the fiber are selected so that the light brightness through the system is maintained or even increased. The light collecting assembly may use a high reflective coating surface or the total internal reflection at an interface. The system of multiple fibered light emitting devices output includes each individual brightness maintaining low loss fiber delivering light unit and the combiner of multiple fibers. This combiner can be fibers bundled together or fused together. The fiber core bundle or fused fiber core bundle includes a light concentration assembly as an alternative.
