  • Patent number: 8773612
    Abstract: A light emitting module (1) comprises a module substrate (2), a light emitting diode string (31), and a sealing member (48). The light emitting diode string (31) includes light emitting diode elements (32) and bonding wires (37) which connect the light emitting diode elements (32). The light emitting diode element (32) has a pair of element electrodes (33, 34) and has a rectangular shape extending in a direction along which the element electrodes (33, 34) are aligned. The sealing member (48) is laminated on the module substrate (2) to seal the light emitting diode string (31). The light emitting diode elements (32) are arranged at intervals in a direction crossing the direction along which the element electrodes (33, 34) are aligned, and the element electrodes (33, 34) with the same polarity are aligned to be adjacent to each other in an arrangement direction of the light emitting diode elements (32) between the light emitting diode elements (32) adjacent to each other.

  • Patent number: 7495379
    Abstract: An object of the present invention to provide a fluorescent lamp in which after formation of a phosphor layer, a glass bulb is bent and in which the phosphor layer is not subject to cracking or peel-off even in bent parts with a small radius of curvature, thus offering a good appearance. A fluorescent lamp includes a glass bulb 1 having bent parts, a protective film 2 having a fine grain layer 2a comprising fine grains of average grain size at most 100 nm and attached to an inner surface of the glass bulb, and large-sized grains some of which are buried in the fine grain layer 2a, the other large-sized grains projecting from the fine grain layer 2a, a phosphor layer 3 formed on the protective film 2 of the glass bulb 1, discharge inducing means 4, 4 sealably installed in opposite ends of the glass bulb 1, and a discharge medium sealed in the glass bulb 1.

  • Patent number: 4716557
    Abstract: An information selection device of a disc player comprises a pickup device (1), a signal processing circuit (12) and a moving device (16). The signal processing circuit (12) comprises a read circuit (13), a write circuit (14) and a comparator (15). At the time of searching a desired piece number and a desired index, these desired piece number and index are written in the write circuit (14). The pickup device (1) radiates a light beam on a disc (8) so that the piece number and the index of the track traced at present are detected by the read circuit (13) at predetermined time intervals from the beam modulated and reflected on the disc (8). Then, the detected piece number and index are compared by the comparator (15) with the desired piece number and index written in the write circuit (14).
