An indoor-outdoor novelty device which simulates moving open flame from the upper end of a standing torch. The device provides a realistic illusion of a bright flame changing its shape and brightness pseudorandomly thru a unique combination of lighting, motion, and airflow under microcontroller control. The device can be viewed from a vantage point in a 360-degree perimeter around the device without compromise to the effect.

A combination for illuminating the interior of a building comprises a fixture and a retrofit kit. The fixture has a base attached to a building ceiling, the fixture having a first tombstone, and a second tombstone. The first and second tombstones are configured to receive between them a fluorescent light tube. The retrofit kit is connected to the base. The retrofit kit includes a light panel, the light panel having a first side facing the fixture and an opposite second side. The light panel resides between the first tombstone and the second tombstone, and the fixture resides above the light panel. The combination is devoid of a fluorescent light tube. The base and the light panel define between them a raceway. A light emitting diode is disposed on the second side of the light panel.

To provide a highly reliable lighting-emitting device that hardly causes defects in case a wiring board is bent, while realizing high brightness by increasing a mounting density of surface-mounted LEDs on a wiring board that is rounded into a truncated cone shape or a cylinder shape, the light-emitting device comprises: the wiring board, a plurality of sets of pads arranged in a line along a circumferential direction of the wiring board, and a plurality of surface-mounted LEDs respectively fixed to the pads. The device satisfies y≤−1.04x+1.80, where (L) is a length of the circumference of the wiring board with the pads, (y) (y=s/L) is a ratio of a total sum (s) of the lengths in the circumferential direction of the pads relative to the circumferential length (L), and (x) is a curvature of the wiring board where the pads are arranged.

A collimating lens (10) is disclosed that is rotationally symmetric around an axis (15). The lens comprises a first body portion (100) comprising an outer surface (110) having at least one recess (140) arranged to receive a plurality of light sources (5, 5′) and an inner surface (120) opposing the outer surface, said inner surface delimiting a cavity (125) and tapering inwardly into the first body portion; and a second body portion (200) extending from the first body portion opposite said cavity and terminating in a light exit window (220), said second body portion having a further outer surface (210) extending between the outer surface of the first body portion and the light exit window and expanding away from the first body portion. Also disclosed is a lighting device that comprises such a collimating lens.

An edge-lit luminaire includes a housing, a lens, a light emitter, a first reflector, and a second reflector. The housing has a central opening that defines a central area. The lens includes a plurality of extraction features substantially evenly distributed over a lens area. The lens is positioned proximate the central opening, and the lens area is larger than the opening area. The light emitter is positioned adjacent the lens and configured to direct light in a direction generally orthogonal with respect to the central opening. The first reflector is positioned proximate a first surface of the lens distal the central opening. The first reflector substantially covers the first surface of the lens. The second reflector is positioned proximate a second surface of the lens opposite the first surface. The second reflector substantially covers the second surface of the lens outside of the central opening.

An integrated light engine including flexible optics and a flexible light source, and lighting devices including the same, are provided. The integrated light engine includes a flexible light source configured to emit light, and flexible optics coupled to the flexible light source. The flexible optics beam shapes light emitted by the flexible light source. The integrated light engine is capable of entering a set of states, such that a portion of beam shaped light emitted by the integrated light engine in a first state is aimed in a first direction and a portion of beam shaped light emitted by the integrated light engine in a second state is aimed in a second direction. Different combinations of the flexible optics with the flexible light source result in the integrated light engine being able to enter a number of flexed states or being held in a substantially flat, substantially stiff state.

A stage light with an additional visual effect includes a main light source and a lampshade, the main light source being located at a bottom of the lampshade. The stage light further includes at least one effect light source and at least one light-transmitting plate located at a light outlet of the lampshade. The effect light source and the main light source are controlled independently of each other. The light-transmitting plate has a first surface and a second surface, and a first side and a second side connecting to the first surface and the second surface, respectively. At least part of the light emitted by the effect light source enters from the first side and exits from the second side. The light emitting by the effect light source exits from the second side, so that the second side is illuminated, which decorates the stage light itself.

The present disclosure discloses a household lighting lamp, including a lamp holder, a main light-emitting component and a secondary light-emitting component; wherein a front panel is provided at a front side of the lamp holder, a mounting portion is provided on a rear side of the lamp holder, the main light-emitting component is provided in front of the lamp holder, the secondary light-emitting component is provided in rear and/or on a side of the lamp holder, and both the main light-emitting component and the secondary light-emitting component are electrically connected to a control circuit. The present disclosure can conveniently adjust the illumination of the lighting lamp, has good light comfort, and can adapt to the needs of users for different scenes.

Arc modular light devices, systems, and methods. In at least one exemplary embodiment of a module system of the present disclosure, the module system comprises a plurality of LED modules, each LED module comprising an outer housing, a light source positioned within the outer housing, and a lens positioned so that light from the light source can be emitted through the lens; and a plate configured to couple to each of the plurality of LED modules; wherein the module system is configured to focus light from the LED modules inward when the plate has a concave curvature; and wherein the module system is configured to spread light from the LED modules outward when the plate has a convex curvature.
