A lighting device is disclosed in the present disclosure. The lighting device includes a support assembly, an illuminant assembly, and a switch assembly. The illuminant assembly is connected to the support assembly and capable of being rotated to the support assembly. When the illuminant assembly is rotated to a position at which an angle between the illuminant assembly and the support assembly is less than or equal to a first angle threshold, the switch assembly turns to an on-state. In this way, the lighting device has a function of a switch.

Luminaires are described herein employing waveguides and associated architectures for dynamic alteration of illuminance distribution patterns. The waveguide includes a light extraction component. The waveguide transmits light from a light source to the light extraction component by total internal reflection (TIR). The light extraction component includes one or more reversibly moveable surfaces for altering illuminance distribution patterns of the luminaire in response to one or more forces applied to the light extraction component by a force application assembly of the luminaire.

A three-section, hingedly connected lighting panel assembly includes a center light panel, a right light panel and a left light panel. The right and left light panels being hingedly connected to the center light panel and foldable over it in a stowed condition of the assembly. Each panel is in its own respective housing that has a rear side and front side. Each of the light panels is provided with a respective plurality of LED lights whose light is aimed in the front direction of each of the panel housings. The hinges connecting the panels to each other are configured to allow the left and right panels to lie in a same flat plane associated with said center panel and to be selectively folded over the center light panel, to facilitate storing and carrying the assembly.

A light fixture includes a supporting unit and a lighting unit including a light emitting module and a lamp shield. The light emitting module includes a base wall and a connecting assembly including a connecting rod connected between the base wall and the support unit, and a connecting sleeve sleeved on and engaging threadedly the connecting rod. The lamp shield includes a fixing plate formed with a peripheral notch permitting the threaded segment to extend removably therethrough so as to be removably clamped between the connecting sleeve and the base wall.

A multi-positional bar shaped light assembly includes a rear housing defining an interior and an open front. The housing further has a rear wall defining two identical sets of mounting holes therethrough, one at a midpoint of the housing and a second set at one end of the housing. The second set being oriented at a right angle with respect to the first set. A printed circuit assembly is mounted within the rear housing and includes a plurality of linearly aligned light emitting diodes arranged thereon oriented to emit light through the open front of the rear housing. A reflector has an open back and is mounted to the printed circuit assembly, and a translucent lens is attached to the rear housing at the open front. A support stand is affixed to the rear housing at one of the first and second sets of mounting holes.

Illuminated top furniture including an illuminated top portion and a support portion. The illuminated top portion includes a support layer, at least one light source, a light diffusion layer and an upper protective layer. The at least one light source is mounted to the support layer. The light diffusion layer is positioned on a side of the at least one light source that is opposite the support layer. The upper protective layer is positioned on a side of the light diffusion layer that is opposite the support layer. At least a portion of the upper protective layer is transparent such that light emitted by the at least one light source is visible through the upper protective layer while the light diffusion layer obscures the at least one light source so that the at least one light source is not visible through the upper protective layer. The support portion is attached to the illuminated top portion to support the illuminated top portion above a ground surface.

Luminaires are described herein employing waveguides and associated architectures for dynamic alteration of illuminance distribution patterns. The waveguide includes a light extraction component. The waveguide transmits light from a light source to the light extraction component by total internal reflection (TIR). The light extraction component includes one or more reversibly moveable surfaces for altering illuminance distribution patterns of the luminaire in response to one or more forces applied to the light extraction component by a force application assembly of the luminaire.

The present disclosure discloses a lamp comprising a lamp body and a connecting rod assembly. The connecting rod assembly is alternatively connected to a first connecting member or a second connecting member respectively to define a first use state and a second use state. When in the first use state, one or more connecting rods of at least three connecting rods which are connected successively in an axial direction define a lifting rod, and a first end of the lifting rod is connected to the first connecting member. When in the second use state, first ends of the at least three connecting rods are connected to the second connecting member, and second ends of the at least three connecting rods are spaced apart from each other to define a placing plane within which a vertical projection of a center of gravity of the lamp body is located.

A humidifier apparatus may have at least one reservoir configured for holding a liquid. At least one device is for creating vapour from the liquid. At least one ventilator may cause a movement of the vapour exiting the reservoir. One or more light sources project lights on the movement of vapour. A method for operating a humidifier apparatus and creating flame-like vapor.

Disclosed is a light emitting panel with improved handling. The light emitting panel includes a fabric made by weaving natural or synthetic fibers, light emitting string parts consisting of a plurality of light emitting devices electrically connected in parallel or series through conductive threads fixed to the fabric, at least one light emitting grid part including an electrode unit connecting the plurality of light emitting string parts in parallel, and a power supply part applying power to the light emitting grid part. The light emitting panel provides an easily controllable illumination area and a uniform luminance. In addition, the light emitting panel is foldable or rollable, achieving improved storability, portability and mobility. Furthermore, the light emitting panel has improved handling even in moist environments such as snowy or rainy days when used outdoors.
