  • Patent number: 6450664
    Abstract: A linear illumination unit (30) has a line of unlensed LEDs (31) which emit light spreading out. The light is focused into a line by a Fresnel lens (33) which allows spread and mixing of light in the linear direction and limits spread in the ortliogonal direction. A Fresnel lens is particularly effective for this purpose. The housings 34 have slots 36 to help control light spread, and the housings are open-ended to allow spread of light in the linear direction beyond the confines of the, geometry of the units. Thus, units (30) may be interconnected to provide seamless linear light in a modular manner.

  • Patent number: 6443584
    Abstract: There is provided a spread illuminating apparatus in which transmission efficiency of light is enhanced and in which a good liquid crystal display screen is provided. Positioning means (25, 25) are provided on a lower plate inner surface (15) of a frame (13) that covers a light conductive member (3). The positioning means (25, 25) push up the light conductive member (3) relative to a transparent substrate (2) in the direction of the thickness of the light conductive member (3) (light source (5)) (toward an upper plate inner surface (14) of the frame) by the thickness t of a reflection preventive film (20) attached to the lower surface of the transparent substrate (2). Thus, an exit surface (9) of the light conductive member (3) does not overlap the reflection preventive film (20), and a good display can be realized on the liquid crystal screen.

  • Patent number: 6439736
    Abstract: A luminaire for suspended ceilings, which permits improved packing density for warehousing and shipping. The reflector of the luminaire is designed to permit it to be shipped in a flattened state. This increases the packing density and eliminates shipping and warehousing boxes whose volume is 95% air. The reflector is typically a single sheet including a top plane with hinged side panels that snap together with interlocking tabs. An assembled luminaire comprises three or four parts: the reflector, a ballasted-socket, a lamp, and an optional diffuser or lens. The reflector, ballasted-socket, lamp, and optional diffuser or lens are either shipped separately in bulk packs or shipped in kits containing the one or more sets of components to build the luminaire.

  • Patent number: 6439752
    Abstract: A method for replacing non-HID landing and taxi lights in an aircraft wing housing that originally was designed to contain the non-HID landing and taxi lights in side-by-side relationship, is accomplished by installing an HID landing light, an HID taxi light and a power control device in the space originally designed to accommodate the non-HID landing and taxi lights. A single ballast provides power to both lamps which each comprise a housing, an HID bulb supported within the housing, a lens for passage of light from the HID bulb out of the housing, a primary reflector surface disposed behind the HID bulb, and a secondary reflector surface disposed in front of the bulb for reflecting light from the bulb back through the bulb for further forward reflection from the primary reflector surface through the lens. The lens may have a lenticular array including a plurality of cylindrical surface elements for spreading the light beam emitted by the lamp.
