摘要： A light reflection assembly, a reflective light source device, and a lamp. The light reflection assembly includes first, second, third, and fourth side walls that enclose a reflection cavity having first and second openings at opposite ends. The first opening is within a first reference plane, and a first reference straight line perpendicularly intersects, at a first intersection within the first opening, the first reference plane. An included angle between a first straight line section that connects first and second end points and a portion of the first reference plane that overlaps the first opening is a first included angle, and an included angle between a second straight line section that connects third and a fourth end points and a portion of the first reference plane that overlaps the first opening is a second included angle, the first included angle being smaller than the second included angle.

摘要： An illumination device includes a plurality of light sources arranged in at least a first group of light sources having one or more light sources and a second group of light sources having one or more light sources and further includes one or more light collectors, each being arranged for collecting light from one or more light sources from the first group of light sources and for converting the collected light into one or more light beams. The first and second groups of light sources are each individually controllable. The first and second groups of light sources are both arranged for emitting light from a space on one side of the one or more light collectors. The illumination device is arranged so that light emitted from the second group of light sources through the one or more light collectors defines a pattern comprising one or more elongated elements.

摘要： An illumination apparatus that is to be disposed in a recess formed in a part of a building includes: a light-emitting module that includes a board and a plurality of light-emitting elements disposed on the board; a light diffuser that has translucency and covers the light-emitting module; and a specular reflector that is disposed between the light-emitting module and the light diffuser. The light-emitting module emits light toward the light diffuser, and the specular reflector reflects light from the light diffuser.

摘要： The back plate has four lateral walls and a bottom plate. A back side of the bottom plate includes multiple sets of folding hooks. Each set corresponds a different installation platform. One of the multiple sets of folding hooks is folded to be used for hooking to a corresponding installation platform. The light source module has multiple LED modules disposed on the bottom plate. Each LED module has a LED device and a lens. The lens diffuses a light of the LED device to be evenly emitted from the lens and broadening an output angle of the light via the lens. The diffusion plate with a peripheral edge is fixed to the four lateral walls of the back plate. The driver cover is attached to an external side of one of the four walls of the back plate. The driver cover defines a container cavity for concealing the driver module.

摘要： An integral conduit modular lighting system that has a light board having circuitry that is secured to a heat sink with an adhesive layer. The heat sink has a gasket in order to securely connect the lighting system to a preexisting conduit body such that the lighting system withstand a high pressure wash without leakage to the board. The heat sink also has opening that mate with openings of preexisting electrical conduit bodies to provide installation of the modular lighting system to existing electrical conduit bodies.
