Precision lighting design is a subcategory of lighting design which benefits from a concerted, synergistic effort to improve beam control; sports lighting is one such example. Beam control is improved when all light directing and redirecting devices are considered together, and insomuch that adverse lighting effects are best avoided when considering how all the lighting fixtures in an array interact with one another. To that end, envisioned is a multi-part visoring (i.e., light redirecting) and optic (i.e., light directing) system designed with consideration towards how a fixture lives in a mounted space—how its photometric and physical presence affects other fixtures in or proximate said space—while demonstrating improved beam control over that which is available to general purpose (e.g., indoor residential) lighting.

A UV irradiation apparatus for coating systems that coat rigid or film-like workpieces, in particular furniture parts, having a transport apparatus for transporting workpieces provided with coating material from an inlet to an outlet through the UV irradiation apparatus, a UV light source arranged above the transport apparatus that irradiates the coated workpieces with UV light in an irradiation region between the inlet and the outlet, and a reflector or cover which shields the UV light source upward. A housing covers the irradiation region and the UV light source, which generally extends above the transport apparatus. A sensor of a measuring apparatus for direct or indirect automated measurement of radiant flux of the UV light source is arranged in the housing, and the sensor is in particular fitted fixed or movably on the housing or a holder. A method for quality assurance using this UV irradiation apparatus is also provided.

The present invention is directed to an apparatus for providing a light reflector, light fixture, light fixture retrofit apparatus, lamp reflector, lamp retrofit apparatus or luminaire reflector retrofit. According to an example embodiment of the disclosed invention, a light reflector is provided that includes annular segments nested as cone-shaped layers configured for reflecting light from a light source placed in proximity to the inner cone portion. The two or more nested cone-shaped annular segments include a reflective surface. The cone-shaped annular segments are configured such that the segment layer having the smallest aperture is located farthest from the light source.

A framing system for shaping light beam comprises a frame support having a number of shutter blades surrounding said light beam, and a number of actuators that move said shutter blades in and out of said light beam. The shutter blades form a merged pile, where part of a first shutter blade is placed over a part of a second shutter blade. A first actuator rotates at least one of said shutter blades in relation to a first rotational point and a second actuator moves the first rotational point in relation to said light beam. A method of shaping a light beam is provided, and involves rotating a shutter blade around a first rotation point using a first actuator, and moving the first rotation point in relation to the light beam using a second actuator.

A dimming device comprises a light source, a support having a light path corresponding to the light source, a light diffuser, and light shielding blades having notches. The blades and the diffuser are movably disposed on the support. The blades and the diffuser are actuated by independent actuators. The notches move into and out of the light path with the movements of the blades, and the diffuser covers a portion of notches that is within the light path when moving into and out of the light path. The diffuser's movement relative to the light path is not limited to that of the blades, so the diffuser can be precisely controlled to move into a specific position within the light path with an optimal trajectory and at an optimal time point. The diffuser is integrally formed without slots, ensuring diffusion of all light passing through the covered portion of the notches.

A beam shading device capable of accurately positioning includes a substrate, a plurality of shading blades mounted on the substrate, and driving mechanisms for driving the shading blades to move. The substrate is provided with a first light-passing hole through which beams pass, the plurality of shading blades are arranged around the periphery of the first light-passing hole, and the driving mechanisms drive the shading blades to move back and forth between blocking and opening the first light-passing hole. Each shading blade is configured with at least two driving mechanisms, and each driving mechanism includes a driving gear and a driving plate. The driving plate is hinged with the shading blade, and the driving plate is provided with a rack that meshes with the driving gear.

A lighting unit includes a board on which a light emitting portion having a semiconductor light emitting device is arrayed on an upper side along the longitudinal direction. The lighting unit also includes a reflector which is disposed on the upper side of the board, and has a reflection portion inside the reflector for reflecting a light from the light emitting portion, as well as covering the light emitting portion. The lighting unit further includes a case disposed so as to support the board and the reflector from the top and the bottom.

The present invention provides a multifunctional light-control accessory frame, which includes at least three accessory borders and at least three angle joints, the three angle joints connecting the three accessory borders to form a frame. An inverted buckling member for being joined with a lamp body is laterally and perpendicularly disposed on a side wall of the angle joint. A sheet mounting groove for mounting a light-control sheet and a lattice mounting groove for mounting a beam-forming lattice are disposed on the inner side of the accessory border. A light shielding plate mounting area and a filter paper clamping plate mounting area are disposed on the outer side of the accessory border. A light shielding plate quick-mounting structure is mounted on the light shielding plate mounting area, at least two positioning plates are disposed on the light shielding plate mounting area, and the light shielding plate quick-mounting structure is locked onto the positioning plates. By means of the light-control accessory frame of the present invention, light-control assemblies can be replaced according to different use requirements, and can be replaced or combined conveniently to satisfy different use requirements.

An optical structure for controlling distribution of light generated by a light source is described. The optical structure includes a primary optics disposed relative to the light source and configured to reflect light generated by the light source towards a target region. The optical structure also includes a secondary optics disposed and aligned relative to the primary optics. The secondary optics is configured to at least partially block light generated by the light source from illuminating a region outside the target region.
