摘要： A method for manufacturing a panel includes forming a path segment on a surface of a substrate from a photoluminescent material. The method further includes overlaying the path segment with an overlay material. The overlay material is configured to render the path segment substantially invisible under an ambient photopic condition and render the path segment visible under an ambient mesopic or scotopic condition.

摘要： According to at least one aspect, a lighting device is provided. The lighting device comprises a circuit board, a light emitting diode (LED) mounted to the circuit board and configured to emit light, a lens disposed over the LED having a bottom surface facing the circuit board, a top surface opposite the bottom surface, and a lateral surface between the top and bottom surfaces, and an elastomer encapsulating at least part of the circuit board. The elastomer may not be in contact with at least part of the lateral surface of the lens so as to form a gap between the elastomer and the lateral surface of the lens.

摘要： A light fixture mounting assembly includes a surface mount, a lighting unit mount configured to engage the surface mount, and an arm connecting the surface mount to the lighting unit mount. The lighting unit mount is movable in use between a first configuration in which the lighting unit mount is disengaged from the surface mount and supported by the arm and a second configuration in which the lighting unit mount is engaged to the surface mount. Moving the lighting unit mount from the first configuration to the second configuration includes moving the lighting unit mount relative to the surface mount in a first direction to cause the surface mount and the lighting unit mount to draw closer together in a second direction that is nonparallel to the first direction.

摘要： Systems and methods for LED lighting, such as systems and methods of use of a warm dimming security light. In one embodiment, the warm dimming security light smoothly changes a security light between selectable configurations, such as those defining light temperature and light distribution pattern. In one aspect, the warm dimming security light changes a security light from a dim warm white look to bright cool white flood light, as triggered by an occupancy or proximity sensor.

摘要： The invention relates to the technical field of stage lights, and in particular to a novel heat dissipation system, a stage light cap body and a waterproof stage light. The present invention discloses a heat dissipation system comprising a heat transfer substrate and a heat dispassion assembly positioned on one side of the heat transfer substrate, a first through hole being arranged on the heat transfer substrate and a displaceable unit used to open and close the first through hole being arranged on the heat dispassion assembly at a position corresponding to the first through hole. The heat dispassion system is simple in structure and convenient to use, and the light source assembly can be taken out for replacement or maintenance without completely removing the heat dispassion system and components alike on the bottom of the stage light cap body.

摘要： The invention discloses a deformable high-power light fixture, which includes a light fixture body, a bracket assembly and other assemblies. The light fixture body includes a light source plate, a heat-dissipating body and a power supply box. The assemblies can be detachable from or sent externally away from the light fixture body. The bracket assembly can be detachable from the main light fixture body also, and it can rotate around its connection point with the light fixture body. The main light fixture body is provided with a glare shield. The present invention uses a common body to achieve various shape changes by splicing, which saves the investment of molds in the early stage and the cost of material preparation in the later stage, so that users can complete the assembly and replacement only by purchasing a single accessory. On the one hand, the glare shield can increase the reflectivity and reduce light loss. On the other hand, it reduces the irritation of light to the human eyes, and also increase the adjustable irradiation area; the light fixture uses a stepless speed dial to achieve fine adjustment of the illumination angle; the bracket assembly can be replaced, and compatible with the tubular installation, supporting pipe diameter 60-86 mm.

摘要： A wall mounting bracket for a light fixture. The mounting bracket has an oblong body defined by oppositely disposed, generally parallel upper and lower surfaces. A mounting surface is disposed at one end of the oblong body, generally perpendicular to the upper and lower surfaces. A stem port passes through the body from the upper surface to the lower surface. A transverse port passes through the oblong body from the mounting surface to the stem port. The stem port has threaded openings in each of the upper and lower surfaces for receiving mounting stems from light fixtures. The mounting surface may be attached to a wall in any orientation or rotation so as to permit light fixtures to be oriented to one or both sides of the bracket.

摘要： A light fixture, e.g., as an artificial skylight, in which light within a region defined by x, y color coordinates (0.37, 0.34), (0.35, 0.38), (0.15, 0.20), and (0.20, 0.14) exits a first light engine, and light within a region defined by coordinates (0.29, 0.32), (0.32, 0.29), (0.41, 0.36), (0.48, 0.39), (0.48, 0.43), (0.40, 0.41), and (0.35, 0.38) exits a second light engine. Also, light fixtures in which a second light engine comprises a sidewall, and light exiting a first light engine passes through space defined by the sidewall; light fixtures in which first and second light engines are able to output light providing different CS values at a luminance; light fixtures in which light incident on a surface of the fixture and cumulative light exiting the fixture have different color points; light fixtures in which light distribution characteristics of light engines differ; and/or other features. The invention also relates to corresponding methods.
