  • Publication number: 20110228415
    Abstract: A high-reflection multilayer coating, which includes a baseplate, a reflecting layer and a composite reflecting layer, in which the reflecting layer is contiguously disposed between the baseplate and the composite reflecting layer, and the composite reflecting layer is provided with a first structure layer and a second structure layer. Moreover, the first structure is mutually contiguously disposed on the reflecting layer. Accordingly, the present invention is able to achieve 95˜100% high light reflectivity over a wavelength range of 400˜800 nanometers, thus increasing light reflectivity and extending the range of reflection. The present invention is able to increase the degree of illumination, brightness and uniformity when used in various types of lamps.

  • Publication number: 20110058381
    Abstract: An optical reflector includes a reflector body (1) having a receiving space (11) and an opening (12). The receiving space of the reflector body has a peripheral wall provided with a reflective surface. The reflective surface of the reflector body includes a light splitting zone (14), two light scattering zones (15) and two light gathering zones (16). The light splitting zone of the reflective surface includes an elongate protrusion (141). Each of the two light scattering zones of the reflective surface includes a plurality of elongate arcuate convex portions (151). Each of the two light gathering zones of the reflective surface includes a plurality of elongate arcuate concave portions (161).

  • Publication number: 20050104624
    Abstract: Embodiments of the invention include a memory controller to interface to memory. In one embodiment, the memory controller includes a pull-up calibration terminal to couple to an external pull-up resistor, a pull-down calibration terminal to couple to an external pull-down resistor, a voltage reference node, a first switch coupled between the pull-up calibration terminal and the voltage reference node, and a second switch coupled between the pull-down calibration terminal and the voltage reference node. The first switch and the second switch may be selectively closed to generate an internal voltage reference on the voltage reference node in a normal mode that may be used for comparison with an input signal to receive data.
