An adaptable decoration and lighting system is provided enabling a method of transforming a systemic device, through moving it between a retracted condition and a plurality of extended conditions, to mimic different holiday icons. The systemic device has a shaft and a plurality of support ribs pivotally coupled thereto to move between the different conditions, whereby the plurality of support ribs move between a parallel relationship with the shaft to radial relationship as it moves between the retracted condition and the plurality of extended conditions. A locking mechanism slidably coupled to the shaft can lock the plurality of support ribs in each condition of the retracted condition and the plurality of extended conditions. Light strings are concentrically attached to the plurality of support ribs along with a decorative accessory or two enable a method of selectively effectuating one of a multiple holiday-inspired configurations of the system.

A LED lighting device includes a seat having a baseplate and a sidewall, the sidewall forming a chamber with the baseplate. A light source disposed in the chamber and attached to a surface of the baseplate. An electric power source is disposed in the chamber and electrically connected to the light source and an optical assembly is disposed on the light source. The optical assembly includes an optical unit and an installing unit, the installing unit is connected to a periphery of the optical unit. The optical unit includes a plurality of first optical members and a plurality of second optical members, and the second optical members are interposed between two adjacent first optical members. The installing unit includes a wall portion surrounding the sidewall, and the wall portion includes a bending portion abutting against an end of the sidewall.

A heat sink, a separator, and a lighting device applying the same are provided. The heat sink comprises: a housing, formed around an axis, wherein the housing has a first open end and a second open end along the axis, and a holding cavity connecting the two open ends. The housing comprises a first portion and a second portion, both formed around the axis, wherein the first portion comprises several device mounting portions distributed around the axis. The second portion comprises an outer fin set disposed around the axis in an outer peripheral region, and an inner fin set disposed around the axis in an inner peripheral region; the first portion is closer to the first open end than the second portion is to the first open end, and the outer fin set extends toward the second open end; each fin extends toward the axis.

An orientation specific luminaire is coupled to lensed optics configured to illuminate vertical and horizontal surfaces within elongated spaces at predetermined light intensity levels, where needed, and with predetermined uniformity ratios within a surface and between surfaces. The orientation specific luminaire includes an orientation mounting hub, the orientation of which is user settable such that the lensed optics emit light from the luminaire's light sources to illuminate vertical and horizontal surfaces within elongated spaces at predetermined light intensity levels.

A luminaire and lighting system for multi-directional lighting for use in photographic, theatrical, and cinematic settings are provided. The luminaire has mounting plates at opposing ends of an elongate body. The luminaire may be mounted onto a stand or other mounting structure at either end of the luminaire to provide different mounting configurations to produce different lighting effects. The luminaire may be used with a lighting modifier to alter the lighting effects.

A modular lighting assembly includes two modular segments, each having a frame member. A coupler for forming an assembly, and an assembly formed by the coupler. In one example implementation, two members having abutment faces are drawn together using a coupler. Each of the members has a T having a T-shaped cross section, and the coupler has channel with a T-shaped cross section. The channel receives the ends of the rails. Each rail has an opening in its top face. Two screws are threaded into a back of the coupler and angled toward a center of the coupler, such that the ends of the screws engage sidewalls of the openings in the rails. As the screws are advanced into the coupler body, the ends of the screws are drawn together, drawing together the abutment faces of the two members. In other implementations, other rail and channel shapes may be used.

A pre-calibrated light box includes a light panel, a material attached to the light panel and at least one LED strip positioned inside the light box and including a plurality of interweaved LEDs selected from three different bins on a chromaticity diagram. The three different bins are selected based on plotting a representative vertex inside each of the first, the second and the third bins and drawing a triangle between the vertices so that a target color of white light emitted out of the light box is located inside the drawn triangle. At least three channels are electrically coupled to each of the bins of LEDs and each channel powers the corresponding bin of LEDs with a proportion of power determined by a geometric location of the target color of white light with respect to a location of each of the bins on the chromaticity diagram.
