A lighting and scorekeeping system particularly applicable to leisure games is disclosed herein. The system is further applicable to games played to a score of twenty-one. Additionally, the system can be operated and customized locally or remotely with a wireless ad hoc network. Light arrays are programmable and/or addressable and uniquely laid out. One or more epoxy inlays are included for ambiance and partial light transmission. In a preferred embodiment, the system is configured to a cornhole game board.

Disclosed is a lighting assembly for providing electrically configured light distributions and illumination patterns. The light distributions can be pre-configured and stored in a memory device or adjusted once installed in an environment by use of a wired or wireless controller or control device. The lighting assembly comprises at least one primary transmissive optical element and multiple light sources arranged in two or more independently addressed electrical channels spatially arranged on a common plane of the lighting assembly housing. Each light source channel is both physically separated and electrically adjustable in order to control light input into the optical element and subsequently adjust the light distribution output of the lighting assembly. The lighting assembly can be used to provide a wide range of symmetric and asymmetric lighting distributions for direct or indirect lighting as well as focusing or defocusing a projected beam in a spotlight or downlight configuration. The lighting assembly is therefore useful in a wide range of typical indoor and outdoor lighting applications including downlighting, spotlighting, wall washing, cove lighting, retail lighting, warehouse lighting. It is also possible to produce useful tunable white or color related lighting effects wherein different color temperature variants of white or different colors, such as red, green or blue might have different lighting distributions.

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.

A light fixture attached to an elongate tubular structure includes a baseplate having a pair of tabs extending from its opposing edges. A printed circuit board (PCB) attached to the baseplate has an aperture aligned with an aperture in the baseplate. An array of light emitting diodes (LEDs) are disposed on the PCB. A mounting bracket attached to the baseplate includes a strap and a pair of clips disposed at its opposite ends. Each clip engages one of the tabs to secure the mounting bracket to the baseplate. A pair of clamp arms extend from the strap and engage an arcuate central portion having a curvature that matches the curvature of the elongate tubular structure. An aperture passes through the strap that is aligned with the baseplate aperture. A power cable passes through the strap aperture, the baseplate aperture, and the PCB aperture. The power cable includes power wires that are electrically connected to the PCB for providing power to the LEDs. A protective cover protects the baseplate and the PCB, and provides for transmission of light from the LEDs.

An LED lamp retrofit system, kit, and method is presently disclosed. The LED retrofit system comprises at least one longitudinally extending LED lamp having a length substantially greater than a width and open longitudinal ends. A first LED lamp support rail holds and covers a first open longitudinal end of each of the at least one longitudinally extending LED lamps and is configured to electrically connect each of the at least one longitudinally extending LED lamps to a power source. A second LED lamp support rail holds and covers a second open longitudinal end of each of the at least one longitudinally extending LED lamps held with the first LED lamp support rail. A system holder on each of the first and second LED lamp support rails is configured and disposed to hold the retrofit system to a portion of a lamp fixture being retrofitted.

Electronic devices for use with deterrent devices are provided. In one aspect the electronic device has a housing, a finger engagement surface shaped to receive a portion of a finger and formed in part by a first contact member movably associated with the housing and in part by a second contact member movably associated with the housing and a control system that determines an output of the electronic device by sensing a movement of at least one of the first contact member and the second contact member. The first contact member, the second contact member and the finger engagement surface are configured so that the portion of the finger received by the finger engagement surface can be urged against a first part of the finger engagement surface to move the first contact member in a manner that can be sensed, can be urged against a second part of the finger engagement surface to move the second contact member in a manner that can be sensed, and can be urged against a third portion of the finger engagement surface to move both the first contact member and the second contact member in a manner that can be sensed.

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.

An underwater lighting system includes a light housing. The light housing includes a weighted base having a bottom surface with a bottom edge and a cover. The cover and the weighted base cooperate to define a cover interior. The cover interior is waterproof. The light housing also includes a light source positioned within the cover interior. The underwater lighting system is configured to prevent a fishing lure or cast net from snagging on the underwater lighting system.

A lighting system (1) has a first lighting circuit (2) configured to provide a first predetermined level of lighting intensity. The first lighting circuit (2) is configured to receive power from a mains electricity supply (3) or from a battery source (4) if the mains supply is unavailable. The first lighting circuit (2) is connected to at least one first Light source (5) and configured, when actuated, to provide lighting at the first predetermined level of lighting intensity. At this time, the first light source is in either an on or off state or a level of light required to raise ambient light level above a predetermined level. The system (1) further has a second lighting circuit (13) configured to provide lighting at least a second predetermined level of lighting intensity. The second lighting circuit (13) is configured to receive power from the mains electricity supply (3) and is connected to at least one second light source (14). The second lighting circuit (13) has at least one sensor (18) with an input such that actuation thereof causes the second light source (14) to provide the second predetermined level of lighting intensity for a predetermined period of time, in response to ambient illumination meeting or exceeding a predetermined intensity, when said sensor has no input or has had no input for a predetermined period of time, or until re-set. In the system (1), the second predetermined level of lighting intensity is greater than said first predetermined level of lighting.

A lighting device (23) irradiates a web under conveyance with light. The lighting device includes a light source (43), and an irradiation port (61) configured to open linearly in a widthwise direction of the web at an end portion facing the web. The irradiation port (61) is formed between first and second parallel portions (62b, 63b) where a first plate member (62) and a second plate member (63) parallelly face each other. The web under conveyance is irradiated with linear light. It is possible to provide a lighting device capable of irradiating only an inspection region of a sheet or a web with light.
