  • Patent number: 9316782
    Abstract: A coverless linear light source light guide with hooded bracket for holding a light emitting diode (LED) module to the light guide is disclosed. The hooded bracket is disposed around the light receiving end of the light guide and comprises a hood top, a hood back, two hood sides, and two hood grasps disposed on the hood sides. The hood back comprises the light receiving end of the light guide where light enters the light guide. The hood grasp comprises grasping elements that mate with grasping elements of the LED module to securely hold the LED module to the light guide. The hooded bracket ensures that the distance between the LED module and the light guide and the angle of the LED module and the light guide is constant which maintains optimal alignment and proximity in order to conserve received light intensity and maintain uniformity of emitted light.

  • Publication number: 20150177454
    Abstract: A coverless linear light source light guide with a light reflecting patterned surface that eliminates the need for a reflective cover is discloses. The light guide comprises an elongated polygonal transparent material. The light reflecting patterned surface comprises a plurality of peaks and a plurality of valleys with a valley disposed between each peak. As the light reflecting patterned surface extends along the light guide the depth of each valley increases and the width of the floor of each valley narrows. Closest to the light receiving end the valley depth is shallowest, the valley floor width is widest, and the height of the peak from the valley floor is shortest. Farthermost away, the valley depth is deepest, the valley floor is narrowest, and the height of the peak from the valley floor is the tallest.

  • 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.

  • Patent number: 7556411
    Abstract: A flickerless light source comprising a transparent or semitransparent diffuser, at least two lightpipes with patterned surfaces inside the diffuser, a single sided LED light source attached to each end of the diffuser, and a dual sided LED light source connecting the lightpipes together is disclosed. The patterned surface of the lightpipes diffuse or reflect light emitted by the single and dual LED light sources and through the lightpipes to provide a light with uniform brightness and intensity. The lightpipes are coated with a thin layer of visible-light transparent material which is doped with organic dye molecules. The organic dye has strong ultraviolet light absorption characteristics. By changing the doping concentration of the dye molecules the coating can become totally opaque or semi-transparent to certain wavelengths and selective wavelength conversion is obtained. In this way light color, brightness, and intensity can be varied or controlled.

    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.

  • Patent number: 6966664
    Abstract: A linear light source having an indented reflecting plane comprises a light guide bar and a light source component. The light guide bar is a polygonal cylinder having an arc-shaped plane. Any two opposed surfaces of the cylinder are an indented reflecting plane and an arc-shaped emission place, respectively. The other surfaces are composed of a plurality of reflecting layers. Through controlling the light-emission slope and height of the indented reflecting plane, the light will be more uniform. The brightness can also be enhanced through the light collecting effect of the arc-shaped emission plane. Moreover, the light source component can let the light emission angle of each LED be closer to accomplish a shorter useless region through the arrangement of the LEDs.

  • Patent number: 6851816
    Abstract: A linear light source device for image reading. The main body of the linear light source device includes at least a light-guide bar and a light source assembly. The light-guide bar is a polygonal column with one surface having stripes thereon, acting as a reflective plane with a reflective function. The opposite plane to the reflective plane is a light-exiting plane, and all the remaining planes are reflective layers. At least one of the ends of the polygonal column is an incident plane for a light beam to enter. Light is transmitted through both of the two ends of the polygonal column (or one end with the other end acting as a reflective plane) and uniformly transmits through the light-exiting plane. The light-guided bar has a simple structure and configuration, a compact volume, a high rate of utilization in light energy, is flexibly changed in length, and is easy to manufacture with high product yield and low manufacturing cost.
