A lighting device may be provided that comprises a housing including an inner surface; a light source unit comprising a body disposed under the housing and a light emitting module disposed under the body; and a reflector disposed between the housing and the body, wherein the body comprises a top surface disposed under the inner surface of the housing and a bottom surface, and wherein the light emitting module is disposed on the bottom surface.

According to the present disclosure, a lighting device provides: an elongate support element, a plurality of lighting units distributed along the length of said support element, each of said units including: a set of electrically powered light radiation sources, a driver supplying said set of light radiation sources with a supply current having an intensity which is a function of an impedance value sensed at a current control input of driver. At least one of said lighting units includes a mounting seat for a lighting adjustment impedance, said seat having an electrical connection to the current control input of at least one driver, so that the intensity of the current supplied by driver to a respective set of light radiation sources is a function of the impedance value of a lighting adjustment impedance arranged at said seat.

A light emitting apparatus and lighting fixture including a plurality of light emitting sub assemblies, each sub assembly comprising a plurality of LEDs. At least one light emitting subassembly comprises a diffuser positioned in front of a light emitting side of the LEDs on the subassembly. At least one of the other light emitting subassembly comprises a reflector reflecting light emitted from the LEDs.

A light guide element and a lamp are provided. The light guide element includes a light-incident surface, a light-emitting surface, an outer surface and an inner surface. The light-incident surface has a first outer peripheral edge and a first inner peripheral edge. The light-emitting surface is opposite to the light-incident surface and has a second outer peripheral edge and a second inner peripheral edge. The outer surface connects the first outer peripheral edge and the second outer peripheral edge. The inner surface connects the first inner peripheral edge and the second inner peripheral edge. A first opening defined by the inner surface adjacent to the first inner peripheral edge is larger than a second opening defined by the inner surface adjacent to the second inner peripheral edge.

An LED luminaire with reduced glare provides a polar arrayed light gradient on a diffuser lens and replicates the appearance of a filament or tube lamp. The luminaire includes a housing having an opening, a diffuser lens extending across the opening, and a plurality of LEDs positioned within the housing behind the diffuser lens. The plurality of LEDs are arranged to generate a composite light pattern having a polar arrayed light gradient across an aperture of the diffuser lens. The polar arrayed light gradient has a light intensity that decreases concentrically with increasing radius.

The invention includes a drop lens that is generally rectangular-shaped and fits over a housing of a light fixture. The drop lens may include two side portions that attaches to and/or engages with the side panels of the housing. The drop lens includes an inner lens that extends between each of the side portions of the drop lens. The inner lens may be preferably constructed of a flexible plastic material so that it can be flexed and bent to engage the side portions of the drop lens. The inner lens disperses the light from the light source, thereby creating a uniform and consistent luminance on the bottom, sides, and ends of the drop lens. Additionally, the invention may include an upper lens that extends between and is slidably engaged with each of the side panels of the housing. The upper lens slides within the housing to hide the light source through a gap or seam between a first drop lens section and the second drop lens section.

A light fixture includes a housing with a skylight aperture, and one or more louver blades spanning the skylight aperture. When open, the one or more movable louver blades block little of the light passing through the skylight aperture; in intermediate positions, the louver blades block a portion of the light; when closed, the louver blades block most light from passing through the skylight aperture. The light fixture also includes: a dimmable artificial light source configured to project artificial light toward the illuminated space; a light sensor that detects light illuminating the space; and a control unit that is integrated with the housing and communicates with the light sensor. The light sensor detects intensity and chromaticity information of the light illuminating the space. The control unit controls position of the louver blades and brightness and chromaticity of the dimmable artificial light source, in response to the light sensor.

In a first aspect, a wallpack lighting fixture is provided herein for use with solid state lighting and which is configurable to selectively utilize different quantities, up to a maximum, of solid state lighting modules, allowing for different levels and patterns of light output. In a second aspect, a wallpack lighting fixture is provided herein for use with solid state lighting which includes a main housing and a secondary enclosure removably mountable to the main housing. In a further aspect, a wallpack lighting fixture is provided herein for use with solid state lighting which includes a housing having a wall mountable back panel and a door portion hingeably, and detachably, connected to the back panel.

Provided is a lighting apparatus. The lighting apparatus comprises a lighting device. The lighting device comprises a first lamp body and a second lamp body. The first lamp body and the second lamp body comprise a first lamp and a second lamp respectively. The first lamp and the second lamp provide lighting when connected to a power source. The first lamp body and the second lamp body are oppositely disposed and can rotate relative to one another.
