Apparatus and method provide underwater lighting to illuminate a site within a body of water in which underwater lighting apparatus is immersed during a lighting cycle. A housing is constructed of a heat-conductive material and LED arrays are affixed to the housing, within a sealed chamber, to conduct heat from the LED arrays to the housing such that heat generated by the LED arrays during the lighting cycle will be conducted directly to the housing and dissipated by the housing to the surrounding body of water. Light provided by the LED arrays is passed through corresponding lens members located for directing light in different directions. At the same time, fouling by marine organisms is resisted.

The present invention provides a lamp unit including an optical member, a base assembly disposed to be spaced a predetermined distance from the optical member with a space therebetween, a light source disposed on the base assembly, and a lens coupled to the base assembly to cover the light source, wherein the lens includes a first protrusion having a first contact surface in contact with one surface of the base assembly and a second contact surface formed at a height different from that of the first contact surface to be in contact with the other surface of the base assembly, and a second protrusion having a third contact surface disposed to be spaced apart from the first protrusion and configured to be in contact with the base assembly, and thus may provide an advantageous effect in that the lens is prevented from being shaken on a substrate as well as being moved on or falling off of the substrate.

An outlet and nightlight device with a solid base. The base has a front, back, top and two outlets on the front the base. There are two plugs on the back of the base, a light sensor, and a light emitter. The front of the base is attached to a raised section which is attached and in moveable communication with a face plate. In some embodiments the face plate slides across the raised section and in others it can rotate away from the raised section via a hinge on the base plate. The light sensor can trigger to the light emitter to emit light in low light conditions and in some embodiments there is a manual trigger for the light emission. In some embodiments the base has USB port for utilization. In some embodiments the face plate can lock to the base plate. In some embodiments the present invention has ancillary light emitters on the raised plate. In some embodiments of the invention there is a battery back up to supply energy to the light emitter in case of power failure.

A coating material composition include a hydroxyl group-containing acrylic resin, a fluororesin, and light diffusive particles, and the hydroxyl group-containing acrylic resin has a weight-average molecular weight in a range of 10,000 to 30,000 and a hydroxyl value in a range of 14 to 70, wherein a mass ratio of the fluororesin to the hydroxyl group-containing acrylic resin (the fluororesin/the hydroxyl group-containing acrylic resin) is in a range of 5/95 to 50/50. The coating material composition can provide the light diffusing properties capable of uniformly diffusing light while effectively masking a light source image.

A lighting system and method electrically control optics of light generated by a light source. The light source generates a light defined by a light distribution. An electro-active optical component changes the light distribution responsive to a change in an electric potential applied across the electro-active optical component by an electronic control system.

A belt-like LED light includes an LED unit with a plurality of LEDs, a belt-like insulating case having a space and a partition plate, and a light-diffusing portion. The LED unit is inserted into the space of the belt-like insulating case, such that at least a part of the light transmits through the partition plate. The light-diffusing portion is continuously installed outside of the belt-like insulating case. The light-diffusing portion includes an open space and a curved section surrounding the open space. The curved section is made of light-diffusive material and diffusing the light having transmitted through the partition plate and the open space. The LEDs of the LED unit are connected with the electric wires for light-emitting. The LED unit is formed capable of being folded standing laterally against the light-emitting direction. The belt-like insulating case and the light-diffusing portion are made of flexible material.

A system and method for creating a trompe-l'oeil skylight in a ceiling where a light emitting image of the sky is provided in a structure configured to emulate a skylight frame, including an embodiment of a unified non-rectangular sky image area in a substantially rectangular fixture which mount as a single unit into a substantially rectangular hole in a ceiling.
