A lighting fixture is provided. The lighting fixture includes a fixture body including an elongated shape, a first end, and a second end. A body mount is disposed at a first end side of the fixture body. A light source is accommodated in the fixture body and configured to emit laser light. A power supply is accommodated in the fixture body and electrically connected to the light source. A light guide includes an entrance end and an exit end. The entrance end is optically connected to the light source. The light guide is configured to guide the laser light from the light source to the exit end. A lamp is disposed at a second end side of the fixture body and optically connected to the exit end of the light guide.

A tool-free light box is provided. Specifically, a top profile, a bottom profile, and vertical rod profiles are spliced on the periphery to form a closed frame. Each profile is provided with two or more hollow cavities, and each end portion of the profile is provided with two or more round holes. An inner wall of the profile is provided with a notch connected to a wiring profile, and a wire passes through a hollow cavity of the wiring profile. Two ends of the wire are connected to a conductive insertion hole, and the conductive insertion hole is embedded into an end portion of the wiring profile. A connector is arranged between the profiles, and the connector is provided with a protruding end. The protruding end is inserted into the hollow cavity of the profile, and a lug boss is arranged on the protruding end.

The present application relates to a lamp bead support and a light fixture, wherein the lamp bead support comprises a frame body and a first circuit board which is connected with the frame body; the first circuit board comprises a first weld portion and a second weld portion which extend out of the frame body; and the first weld portion and the second weld portion form a snipping opening at the outside of the frame body.

Disclosed are pharmaceutical compositions comprising brimonidine and timolol for topical ophthalmic delivery and a method of treatment comprising administering said composition when indicated for glaucoma and associated conditions such as elevated intraocular pressure in the eyes of humans.

An illumination device (e.g., an electric candle, etc.) generally includes a shell, a housing coupled to the shell, a first light source, and a pendulum supporting the first light source generally above the housing, wherein the pendulum is pivotally coupled to the housing and configured to move the first light source relative to the housing. The device also includes a flame-shaped head, where the first light source is disposed within the flame-shaped head, and a second light source arranged inside the shell and configured to illuminate the shell from the inside out. A printed circuit board assembly is arranged inside the shell for controlling operation of the first light source and the second light source.

An LED tube light with a color adjustment switch related to the technical field of home appliances includes an LED tube light body. The LED tube light body is provided with a tube light body and terminals located at two ends of the tube light body and used for connecting with a mounting seat. The tube light body includes a light tube, an LED light strip with at least two different color temperatures, and a driving power source electrically connected with the LED light strip. The LED tube light body further includes at least one color adjustment switch fixed on the respective terminal. The color adjustment switch is configured to control the on and off of different color temperatures of the LED light strip.

The present disclosure provides a light bar, a backlight assembly and a display device. The light bar includes a substrate; a first metal layer disposed on a first side of the substrate and comprising a plurality of first metal segments disposed at intervals along a length direction of the light bar; a second metal layer disposed on a second side opposite to the first side of the substrate and comprising a plurality of second metal segments disposed at intervals along the length direction of the light bar, a projection of the interval between two adjacent first metal segments on the substrate falls into projections of the second metal segments on the substrate, and a projection of the interval between two adjacent second metal segments on the substrate falls into projections of the first metal segments on the substrate.

A modular troffer-style fixture particularly well-suited for use with solid state light sources. The fixture comprises a reflector that includes parallel rails running along its length, providing a mount mechanism and structural support. An exposed heat sink is disposed proximate to the reflector. The portion of the heat sink facing the reflector functions as a mount surface for the light sources. The heat sink is hollow through the center in the longitudinal direction. The hollow portion defines a conduit through which electrical conductors can be run to power light emitters. One or more light sources disposed along the heat sink mount surface emit light toward the reflector where it can be mixed and/or shaped before it is emitted from the troffer as useful light. End caps are arranged at both ends of the reflector and heat sink, allowing for the easy connection of multiple units in a serial arrangement.

An emergency lighting unit includes a housing. The housing includes a base having a first portion and a second portion. A lamp assembly is rotatably connected to the housing and positioned in the lower portion. A cover is provided over the lamp assembly.

A lighting engine, system and method of fabrication are described. The system contains a flexible printed circuit (FPC) shaped as a loop. LEDs are mounted on the FPC to emit light toward a center of the loop. A light guide positioned in an interior of the loop receives light emitted by the LEDs through an edge of the light guide. The light guide has slots formed therein that receive locator pins to limit thermal displacement of the light guide towards the LEDs. Other apparatuses, systems, and methods are also disclosed.
