  • Patent number: 6914369
    Abstract: A quick temperature-raising structure of cold cathode fluorescent lamp comprises a cold cathode fluorescent lamp, a soft electric heating component, an insulating tube and two insulating components. The soft electric heating component adheres onto the surface of the cold cathode fluorescent lamp. The insulating tube is slipped onto the surface of the cold cathode fluorescent lamp. The two insulating components are slipped onto the joint portions at two sides of the cold cathode fluorescent lamp, the soft electric heating component and the insulating tube. Grooves are formed on the insulating components so that an external power source can provide the working power for the soft electric heating component and the cold cathode fluorescent lamp via conducting wires. The soft electric heating component can heat in advance to quickly raise the ambient temperature of the cold cathode fluorescent lamp when the cold cathode fluorescent lamp is driven.

    Abstract: A surface light source device comprises a light guide plate 15 having a back face 15E opposite with an emission face, the back face 15 being provided with a great number of micro-reflectors 19 and ridge-like projections 20. A U-shaped fluorescent lamp 14 is disposed along a plurality of end faces 15D, 15E and 15C.

Each micro-reflector 19 realizes direction-conversion mainly through successive double inner-reflections at a pair of slopes. Light introduced into the light guide plate 15 through the end face 15C, which extends in a direction generally perpendicular to the end faces 15D and 15E, is direction-converted by the ridge-like projections 20 having a pair of slopes 20A, 20B to be directed to a generally frontal direction end emitted from the emission face.

  • Patent number: 6820997
    Abstract: A lighting system for projecting a soft light with a flat reflector to provide a fill light with minimal spill light. Conventional light sources, U-shaped glass, fluorescent tubes preferably having phosphor coatings, are located at a position other than parallel to one another, that is, the socket assemblies are mounted in a V position at about 110° angle to opposing ends of the lighting fixture assembly. This placement provides a greater light output than is achievable by positioning the light sources parallel to one another, in addition to increasing the number of tubes used in the small space, thus decreasing the size and/or weight of the housing and increasing the light output. Furthermore, the fluorescent tubes will act as a reflector due to the angled position.

    Abstract: Linear lamp energy output is tuned by adjusting the reflectivity of reflectors or shade members used to direct, focus and filter energy output of a linear bulb. Reflectivity is reduced in areas of the reflector contributing to high irradiance levels in a target area allowing, for example, overall equalization of irradiance across the target area. An outer surface of the linear bulb may have a modified diameter, light transmission reducing surface treatment or an added sleeve to linear bulb areas contributing to irradiance levels in specific locations in the target area that are higher than desired. Alternatively and or additionally, a lens or shade member having a graduated convergence, reflectivity and or transmisivity may be used.

  • Patent number: 6779910
    Abstract: A recessed light fixture with body, reflector and electrical box formed as one piece, preferably of a polymeric material. The fixture includes a self-mounting feature and a seal against air infiltration into unconditioned spaces. The reflector has special geometry that provides symmetrical distribution of light. The lamp socket tilts downward to facilitate lamp changes. The design moves the heat sensitive components of the electronic ballast far from the heat produced by the lamp. The fixture may be installed from the occupied side of the room, eliminating the need for an installer to crawl in attic spaces.

  • Patent number: 6773130
    Abstract: A lighting system and components are described for a lighting assembly, including a socket having a socket body and an electrical connector with a seal in the socket to seal around a light source. The socket is preferably configured to be independent of the mounting arrangement for the lighting assembly. An insulator is also disclosed for a lamp such as a fluorescent lamp having a body which protects the contact on the lamp so as to form a recessed lamp conductor. The combination of a socket and lamp insulator is also disclosed for providing a socket and insulator assembly for reducing the possibility of injury or damage due to high open circuit voltage, environmental effects and the like. Additionally, a lighting assembly is disclosed incorporating the insulator, socket and mounting arrangements.

  • Publication number: 20040141307
    Abstract: A backlight module, suitable for supplying a plane light source. The backlight module has a light guide plate, a reflection mask and a light compensator. The light source is disposed next to a side surface of the light guide plate, such that the light generated thereby is incident on the side surface of the light guide plate, transmitted through the bottom surface, and projecting from the top surface of the light guide plate. The reflection mask is disposed next to the sidewall of the light guide plate to cover the light source. The light compensator is disposed in the reflection mask. By disposing the light compensator with multiple reflection planes in the reflection mask or forming multiple reflection surfaces of the reflection mask, the brightness at the two comers of the light guide plate near the two sides of the light source can be compensated.

  • Patent number: 6761470
    Abstract: A controller for a lighting system is integrated with a light or other device. The controller operates in a local mode to control the integrated light only and in a remote mode to function as a serial network protocol controller for a series of connected devices. In remote mode, an IR/RF remote control is used to change settings for any device connected to the controller. The controller generates a fast serial network protocol instruction sequence, such as a DMX-512 protocol instruction sequence, from the commands received relatively slowly from the IR/RF remote control. The controller can include an hours of operation counter for the integrated light and a global setting function for changing all connected devices simultaneously to a single setting.

  • Patent number: 6758576
    Abstract: A portable stack lamp includes a base supported by a supporting device, such as an extensible tripod and a plurality of rolling wheels, two or more lamp units stacked up to form a stack-up lamp body mounted on said base, and a cover which is adapted to cover a top opening of the housing of the lamp unit having a handle affixed thereon. The portable stack lamp is arranged to provide 360 degrees illumination so as to produce luminous beams in all directions while the user is able to selectively increase or decrease its luminous intensity by simply stacking up more or less lamp unit easily anytime. Therefore, the portable stack lamp can illuminate the surrounding that not only minimizes the number of work lamps to be used but also saves both the electrical energy and illumination cost.
