Abstract: An apparatus, method, and system to provide, as one example, up-light for aerial viewing from downwardly aimed wide area, high intensity, lighting fixtures. The method controls a small percentage of light from the fixture to pass up and away for up-light, with the remainder used to produce a controlled, concentrated beam to a target. Some embodiments include a substantial amount of glare and spill light control. An apparatus can include a lamp and fixture with a visor length that is shorter than most conventional spill and glare control visors. The visor allows a controlled, relatively small percentage of direct light from the fixture for a desired or needed level of aerial illumination, but efficiently directs other light to the target. Optionally, a reflective plate is positioned inside the visor to reflect a small percentage of light from the fixture upwardly for up-light. Another embodiment can shift a fraction of light in direction(s) different than the main light output of the fixture.

Abstract: A light source for endoscopy or microscopy comprises a lamp, a heat sink, the heat sink being thermally connected to the lamp and at least one heat pipe, which is thermally connected to the heat sink and which dissipates the heat that is generated by the lamp and transferred to the heat sink.

Abstract: A lamp is disclosed that includes a light source that requires high voltage for starting. A reflector body includes an electrically conductive reflective surface that is oriented to receive light from the light source and direct the light in the desired direction. A preselected surface portion of the reflector body is devoid of the electrically conductive reflective surface. First and second lead assemblies associated with the light source, and that supply power thereto, pass through openings in the reflector body. The lead assemblies are spaced from the electrically conductive reflective surface portion by the preselected surface portion that is devoid of the reflective material to preclude arcing. Asymmetrical lead wire assemblies may also be advantageously used to increase the electrical standoff.

Abstract: An input image signal 101 is divided into MC block units and, when coding processing is performed in these divided units, a motion compensation section 107 generates a motion-compensated prediction image 106a by detecting movement amounts in predetermined MC block units, a smoothing filter section 124 performs, with respect to the prediction image 106a, smoothing of pixels located at the boundaries of adjoining MC blocks on the basis of predetermined evaluation criteria, and a prediction residual signal 108, which is obtained from the difference between the prediction image 106b obtained by the smoothing, and the input image (input image signal 101), is encoded.

Abstract: The present invention provides a high-pressure discharge lamp having a long life. A high-pressure discharge lamp (100) comprises a light emitting part (4); first and second sealing parts (6, 8); first and second electrodes (10, 11); a first conductive lead (21) wound around the first sealing part; a first lead wire (22) electrically connecting the first conductive lead to the first electrode; a second conductive lead (25) wound around the second sealing part; and a second lead wire (26) connecting the second conductive lead to the first electrode. The second lead wire detours the light emitting part to avoid being affected by heat. After the lamp is turned off, the temperature of base parts of the electrodes immediately falls, and much mercury can be collected in the vicinities of the base parts.

Abstract: A device and method for illuminating the interior of a balloon. The device includes an elongated tube that is between three inches and twelve inches in length. A light source, such as an incandescent bulb or an LED, is coupled to one end of the elongated tube. A wire passes through the center of the tube and provides power to the light source. The elongated tube is passed into the collapsible fill conduit of a mylar-type of balloon. The elongated tube supports the light source in the interior of the balloon. The collapsible fill tube collapses around the elongated tube, thereby creating a substantially air impervious seal in between the balloon and the elongated tube. The presence of the wire in the elongated tube enables the light source in the tube to be coupled to a power source outside of the balloon without allowing the air in the balloon from escaping.
