Abstract: Systems, software, and methods are provided for efficient, dynamic lighting control. In an embodiment, a two-channel LED lighting system is dynamically controlled to emulate dimming of an incandescent fixture. In an example, a lighting fixture may include red, green, blue, and white emitting LED modules. The lighting fixture may be controlled such that it produces generally white light from about 2150K candle light color to 5500K daylight white color with only 4 LEDs. Furthermore, the white LED may be controlled such that the white LED CRI is approximately 95 to ensure optimal results when mixed with red and green. In another embodiment, a dynamic two-channel LED lighting system is controlled to emulate dimming of an incandescent fixture. Specific dimming protocol can allow for efficient dimming which helps minimize the height of a linear light fixture and maintain diffusion with multiple colored point sources at minimal pitch.

According to the invention, the assembly is developed further by the fact that the intermediate Spaces between the light-emitting diodes comprise a heat-resistant or fire-resistant or non-combustible material and/or that a front panel comprising a heat-resistant or fire-resistant or non-combustible material is provided. The invention also relates to a video board.

Abstract: A novel heat sinking technology, uniquely adaptive to LED lighting devices in a generally LED array format containing multiple openings on said heat sink's base portions and optionally fin portions providing “short path cooling” technology. The “short path cooling” technology is thoroughly taught with multiple examples. Also taught, are methods of heat sink area maintenance when said openings are placed on said heat sinks. Indeed, even surface area increases are shown to be possible when multiple openings are placed on said heat sinks. Lastly, other non-LED semiconductor cooling is discussed and illustrated in various figures using said “short path cooling” technology.

Abstract: A power and control assembly is disclosed. An LED driver is sized and adapted to fit within a single compartment of an electrical gang box, such as a two-gang box. An alternating current (AC) dimmer or other component is installed in an adjacent compartment. The AC dimmer supplies its output to the LED driver, which converts the AC power to an appropriate direct current (DC) power for LED lighting fixtures. The LED driver is typically recessed into the compartment, and is covered by a switch or another control element. In some cases, the switch may be a mechanical dummy selected for its aesthetic or fascial characteristics. In other cases, the switch or control element may be functional. With similar multiple-gang boxes, a number of drivers may be installed in the gang box and switches may allow both dimming and zone control.

Abstract: A strip of linear lighting with distributed power conversion is disclosed. The linear lighting includes a flexible PCB. The flexible PCB is divided into repeating blocks, which are arranged electrically in parallel with one another between power and ground. Each repeating block includes power conversion and conditioning circuits. A plurality of LED light engines are connected to the outputs of the power conversion and conditioning circuits, electrically in series with one another. The power conversion and conditioning circuits typically include at least a full-bridge rectifier, and a filter may be connected to each of the LED light engines. A pair of conductors run the length of the PCB adjacent to it and are connected to each of the repeating blocks. A flexible, transparent covering surrounds the PCB and pair of conductors.
