摘要： Opto-thermal system for lighting devices with heat dissipating elements, mainly for LED radiation sources, based on two different configurations: parallel and “floating-source” configuration, with one or several bidimensional flat faces, straight or bent, thermally conductive, by phase change or thermal conduction, which directly transmit the heat generated by the radiation source, which is in a central region of the system, in thermal contact with a central area of the plate or in the union of plates, towards peripheral regions, by contact of the flat faces of the plates with the fins, radiators or other flat faces of the body of the device. This system improves the dissipation of heat, the use of space in the devices, and, if it is configured as a floating-source, it makes possible an optical-reflective assembly where all the radiation from the source is reflected and controlled by the reflector.

摘要： A family of lighting systems uses a small number of standard parts or extrusions. The extrusions include end elements, spars, and heat sinks. Lightbars and uplights, having heat sinks, LED arrays, and lenses, use heat sinks with the same extrusion profile. The extruded parts can be slid together and then held in place by screws holding side panels to form a housing. Conditioned electrical power can drive the LED arrays. The conditioned power can be produced by power conditioners mounting on the housing. IP65, or better, components can be used to produce a rugged outdoor system.

摘要： A light-emitting device holder is configured to fix a light-emitting device to a mounting object. The light-emitting device includes a substrate, a light-emitting element, and a pad. The light-emitting device holder includes a holder main body, a terminal and an insulating member. The holder main body defines an opening at a position corresponding to the light-emitting element in a fixed state after the light-emitting device is fixed to the mounting object by the light-emitting device holder. The terminal is attached to the holder main body, and configured to be in contact with the pad in the fixed state. The insulating member is attached to the holder main body, and configured to be in contact with at least a region of the surface of the substrate between the pad and a portion of an edge of the substrate that is closest to the pad in the fixed state.

摘要： An adjustable lighting apparatus includes a lighting module that is rotatably adjustable about a first rotation axis relative to an adjustable mount. The lighting module may include a heat sink, a driver, and a light source. The adjustable mount may include a base structure, a retainer, a shield, and a secondary shield. A trim may also be coupled to the adjustable mount. In some implementations, the lighting module translates along a first translation axis defined by the adjustable mount while rotating about the first rotation axis in order to reorient the light source while reducing shading losses caused by the adjustable mount. Openings in the base structure and the shield may be substantially covered at all rotational positions of the lighting module using a combination of the shield, the trim, the heat sink, and the secondary shield, thus eliminating the need for an additional enclosure.

摘要： A resistance control device and its lamp. The resistance control device includes: a shell, which is provided with an accommodating chamber and the first opening and the second opening connecting the accommodating chamber; and a control module, which includes the resistor and the external plug in the accommodating chamber. The external plug is electrically connected to the resistor. One end of the external plug is set extending the first opening. The external plug is used to connect the resistor to the lamp; and a boosting part, which is connected to the resistor and exposed in the second opening. The boosting part is used to twist or toggle the resistor to adjust the resistance value of the resistor accessing to the lamp. The resistance control device can be removed to achieve the quick separation and assembly of the lamp and improve the use convenience.

摘要： The present teaching relates to an illumination module for emitting light directed in parallel in a main emission direction, having a reflector with a focus lying on the front side thereof. At least one LED light source is arranged substantially at the focus of the reflector for radiating light into the reflector. A heatsink is arranged on the rear side of the reflector. The LED light source is oriented counter to the main emission direction. The reflector is configured to direct the light radiated into the reflector by the at least one LED light source in parallel and emit the light in the direction of the main emission direction. The at least one LED light source is held by means of at least one connecting web extending from the heatsink to the LED light source.

摘要： In order to make it possible to image the surface of a workpiece from a plurality of directions without reducing the amount of light to be projected to the workpiece, a light projection device having light emitting surfaces opposite to the workpiece and formed with a slit allowing light reflected by the workpiece to pass from the light emitting surface side toward an opposite side thereof is adapted such that the slit is formed in a tapered shape whose width gradually increases from the light emitting surface side toward the opposite side.
