  • Publication number: 20100254016
    Abstract: A symmetrical lens array comprising two identical covers, two identical lens sections, and a middle holder. Each lens section comprises a plurality of lenses disposed on the top and bottom of the lens section. The lens array is assembled with the middle holder positioned between the two lens sections. The two covers are positioned one cover on the top of the upper lens section and one cover positioned on the bottom of the lower lens section. Mating elements of the covers, lens sections, and the middle holder mate to allow the components to attach and be held together. Since each lens section is identical and each cover is identical the same lens section tooling is used for all lens sections and the same cover tooling is used for all covers.

  • Publication number: 20100124063
    Abstract: A miniaturized linear light source sub-module comprising a symmetrical lens array, a light guide bar with dual reflecting surfaces, at least one light emitting diode light source, and a sub-module housing is disclosed. The symmetrical lens array comprises two identical covers, two identical lens sections, and a middle holder. Each lens section comprises a plurality of lenses disposed on the top and bottom of the lens section. The dual reflecting surface light guide comprises a light emitting surface, a v-shaped light reflecting surface, an asymmetrical saw-toothed light reflecting surface, an apex cut-off surface, and a bottom cut-off surface. At least one light emitting diode light source is connected to an end of the dual reflecting surface light guide. The sub-module housing holds the lens array assembly, the dual reflecting surface light guide, and the at least one light emitting diode light source to form the miniaturized linear light source sub-module.

  • Patent number: 7696984
    Abstract: An optical mouse system with a high-angle optical path features small size and low power consumption. The illumination source and optical sensor are mounted in the same plane, directly on the PCB. The higher angle of the optical path causes more light to be reflected to the optical sensor, increasing optical efficiency and allowing a smaller, lower powered LED to be used. This also results in increased sensitivity of the optical sensor, allowing use of the mouse on surfaces on which conventional optical mice cannot function adequately. Sensitivity can be further increased by optional isolation of the optical sensor and illumination source. Lower power usage increases battery life for mobile or wireless-mouse use, while reducing thermal waste considerations. This allows the creation of a significantly smaller form factor for the overall package, thereby reducing materials costs and giving designers more flexibility for external design considerations.

  • Publication number: 20080094717
    Abstract: A focus optical lens array assembly has two lens sections each encased in a housing. The housings are made of black polymer to block unwanted scattered or external light. The lens assembly can all be made by injection-molding. Notches, locating holes, posts, and ears serve to orient and align the parts, and to prevent incorrect assembly. The housings include a plurality of holes that extend to the edge of the individual lenses. This prevents any unwanted light from passing to other adjacent lenses. As a result, cross-talk is reduced and ghosting is prevented.

  • Publication number: 20070297189
    Abstract: A light guide assembly as a linear light source for enhancing the uniformity of beaming light within the beaming light's effective focal range comprising a light guide bar connected to a light source assembly and a reflective housing encasing the light guide bar. One surface of the light guide bar is a light-scattering/light-emission surface, and other surfaces are all reflective. The emission plane has gradually changing indentations for adjusting the light refractive and reflecting indexes to ensure the light uniformity. The reflective housing covering the light guide bar is used for enhancing the light reflection and intensity. An opening is formed in the reflective housing corresponding to the emission plane of the light guide bar, and a reflecting flange is formed at one side of the opening.

  • Patent number: 7256941
    Abstract: An optical lens array featuring low cost and simple manufacture. The lens array has two lens sections separated by spacers, with a stop on the front surface. An optional wraparound frame protects the lens array from external light. The spacers and stop, as well as the optional frame, are made of black polymer to block unwanted scattered or external light. The lens sections, stop, spacers, and frame can all be made by injection-molding. Notches, locating holes, posts, and ears serve to orient and align the parts, and to prevent incorrect assembly.

An opening is formed in the reflective housing corresponding to the emission plane of the light guide bar, and a reflecting flange is formed at one side of the opening. Combined with the sloping and notched emission plane, light with high intensity and uniformity can be obtained, and the uniformity of beaming light within the beaming light's effective focal range can also be improved.
