A troffer is a rectangular light fixture that fits into a modular dropped ceiling grid (i.e. 2' by 2' or 2' by 4'). Troffer fixtures have typically been designed to accommodate standard fluorescent lamps (T12, T8, or T5), but are now often designed with integral LED sources. Troffers are typically recessed sitting above the ceiling grid, but are also available in surface mount 'boxes'.

Semiconductor light-emitting device and manufacturing method of the same
InactiveUS20100258830A1Reduce the amount requiredTelevision system detailsDischarge tube luminescnet screensEffect lightEngineering
Light from a semiconductor light-emitting element travels in all directions. Thus, light that travels in the directions other than a lighting direction cannot be used effectively. Means for forming a semiconductor light-emitting element having tilted side surfaces, and forming a reflective layer on the tilted side surfaces has been proposed. However, since the tilted surfaces are formed by an etching method or the like, it takes a long time to form the tilted surfaces, and it is difficult to control the tilted surfaces. As a solution to these problems, semiconductor light-emitting elements are placed on a submount substrate and sealed with a sealant, and then a groove is formed in a portion between adjoining ones of the semiconductor light-emitting elements. The grooves formed are filled with a reflective material, and a light-emitting surface is polished. Then, the submount substrate is divided into individual semiconductor light-emitting devices. Thus, a semiconductor light-emitting device having a reflective layer on its side surfaces can be obtained.

The invention provides a light guide member and an illuminating device which are able to efficiently uniformly irradiate illumination light to only an area requiring illumination. Therefore, a reflection face is constructed by reflection stripes such as many grooves, etc. widened in a concentric circle shape. Light from a light source unit is widened toward this entire reflection face without irregularities by a diffusing portion such as a reflection prism, etc. Thus, only the range actually requiring the illumination can be illuminated without irregularities, and visibility of the illumination range using a front light is raised.

Troffer-style lighting fixture with specular reflector
An indirect troffer-style lighting fixture that is particularly well-suited for use with solid state light sources. An elongated heat sink with a mount surface for light sources runs longitudinally along the fixture. To facilitate heat dissipation, a portion of the heat sink is exposed to the ambient room environment. An elongated specular reflector also runs along the device proximate to the heat sink. The heat sink and the specular reflector are mounted such that a spatial relationship is maintained. Some of the light from the sources impinges directly on the specular reflector and is redirected towards a back surface. The back surface defines a luminous surface that receives light directly from the sources and redirected light from the specular reflector. The back surface and the heat sink mechanically obscure any images of the light sources in the specular reflector such that they are not visible in a viewing area.
