A light fixture includes a visible light module and a germicidal light module. The visible light module may include one or more visible light engines designed for emitting visible light for general illumination. The visible light module may define a top side, a bottom side opposite the top side, and an outer perimeter around the top side and the bottom side. The visible light module may define an aperture extending through the visible light module from the top side to the bottom side. The visible light module may be designed to emit the visible light out of and across the bottom side from the outer perimeter to an inner perimeter defined by the aperture. The germicidal light module may be coupled to the visible light module. The germicidal light module includes a germicidal light engine designed to emit germicidal light through the aperture effective in deactivating pathogens.

The present invention may be directed to an improved LED downlight with enhanced features including a multi-adjustable junction box and cover assembly, and arm and hinge mechanisms for better installation and packaging of said improved LED downlight. The versatile configuration of the junction box, mounting plate arm, and hinge mechanisms may allow the entire assembly to be maneuvered over various sized ceiling holes for ease of driver and LED replacement and maintenance. Other features and improvements may include compact compressible and expandable three-piece hangar bar mounting brackets, an integral air-tight box, and/or a system for mounting the improved LED downlight to various ceiling thicknesses. The improved LED downlight may be used in both new construction and remodel retrofit installations, sharing the majority of parts, providing ease and flexibility for the installer.

The present disclosure discloses a lighting lamp, the lighting lamp includes a housing, a control system and a first light source module, the housing has a light exiting port, the first light source module includes a light guide plate and a first red green blue (RGB) light source, the control system controls the first RGB light source to emit first light of a first predetermined color, the light guide plate is installed on the light exiting port, the light guide plate includes a first plate surface facing outside of the housing, a second plate surface facing inside of the housing, and an outer peripheral surface connecting the first plate surface and the second plate surface, the first RGB light source faces the outer peripheral surface, wherein the first light enters the light guide plate through the outer peripheral surface, and exits the light guide plate through the first plate surface.

A housing assembly for a recessed lighting system includes a housing with integrally formed cable routing features, mounting features, and alignment features. The integration of multiple features into the housing is enabled by forming the housing from a polymer using an injection molding process instead of sheet metal. For a new construction installation, the housing includes integrally formed bar hanger holders to support and guide bar hangers for installation onto two or more support structures, nail-in features for installation onto a single support structure, and one or more alignment features to position the housing against the single support structure when the nail-in features are used for installation. For a remodel installation, the housing includes a flange to abut a bottom surface of a ceiling and one or more spring clips mounted to the housing to abut a top surface of the ceiling.

An optical display device that creates a perception of a sky scene in output light, the device comprising: a light source; a reflector block having a reflective member and a reflective and partially transmissive member; a diffuse light generator; a visual cue creating system associated with the reflector block, and an aperture for the output light, the light source arranged to transmit light to the reflector block for reflection between the reflective member and reflective and partially transmissive member, with light transmitted through the reflective and partially transmissive member to the aperture, the diffuse light generator arranged to generate in the output light a diffuse light component to replicate a skylight from the light transmitted from the light source, the visual cue creating system causes light in the reflector to block a visual cue arranged to provide in the output light a visual cue component that observers associate with depth.

An LED downlight assembly accommodates square and round trims and its components may be removed irrespective of the presence of mudded in round or square mud plates. The assembly also comprises a collar that can be fitted to ceiling of varying thicknesses.

The present utility model discloses a downlight that belongs to the technical field of downlights and is suitable for embedded tubes of different specifications; the downlight includes a lamp cup; a drive board is arranged inside the lamp cup, and a light source board is arranged below the drive board; a lampshade is arranged below the lamp cup, and two symmetrically arranged mounts are arranged on the lamp cup; and a spring is rotatably embedded in the mount. The spring of the present utility model can be rotated in the mount along the transverse axle at the bottom of the installation bracket, so as to adjust the relative distance between the two springs, such that one downlight can be applied to the installed embedded tubes of different specifications, thereby saving the cost of manufacturers in inventory storage and reducing the models of downlights purchased by users; the present utility model uses a triangular limit block, which has a horizontal bottom face for limiting the spring and an inclined side face for installing the spring.
