  • Patent number: 7819537
    Abstract: A flash unit for an image capturing device includes a main body and a flash tube. The main body has a light emitting surface, a light reflecting surface, and two opposite end surfaces. The light reflecting surface is formed with a light-reflective film. The main body is made of transparent material and defines a through hole running through the two end surfaces. The flash tube is received in the through hole.

    Abstract: A lighting fixture for improving luminance of a lamp tube includes a curved reflecting plate and a lampshade. The lampshade has partition plates with arc surfaces, side plates with inclined planes and end plates with curved surfaces. The lamp tube is disposed at a longitudinal axis of the curved reflecting plate. The reflecting plate reflects the light emitted from the lamp tube and the light reflected from the partition plates to the environment. The side plates are inclined with a certain angle for guiding light, and the end plates with curved surfaces are used to enhance the reflecting light. Thus, light output efficiency is improved and glare is reduced.

  • Publication number: 20100046214
    Abstract: A retrofit kit is configured for a single or multiple tubular fluorescent lamp fixture. The original fixture being retrofitted may or may not have any reflectors. The kit includes a new improved reflector with double concave wings. The winged reflector preferably has a central arched, preferably trapezoidal portion which forms the lower cover of the fixture box. This central trapezoidal portion includes an access door to permit access to the ballast without the need to remove the winged reflector once it is installed. An arched, preferably trapezoidal socket bar is installed at each end of the fixture, to lower the position of the lamp with respect to the winged reflector surfaces, to enhance the light distribution in a downward direction while permitting enhanced up-lighting. The distal ends of the trapezoidal central portion of the reflector mate with the trapezoidal socket bars at opposite ends of the fixture.
