An illumination device including a lamp and a light pole is provided. The lamp has a first assembling structure. The light pole has a second assembling structure. When the lamp moves closer to the light pole, the first assembling structure and the second assembling structure are automatically locked together by transmitting and receiving a signal. In addition, an installing method of an illumination device is also provided.

A camera-integrated LED lighting device includes: a body unit having a lower surface at which a part of a camera unit is exposed, and having a power supply unit embedded therein; a lighting unit coupled to the front surface of the body unit, and including a plurality of LEDs and receiving power provided from the power supply unit of the body unit so as to provide light; a connecting unit arranged on a rear surface of the body unit so as to be coupled to a support or an arm; and a camera protection unit protruding from the lower surface of the body unit along the circumference of the camera unit.

An improved structure of a lighting display device includes a lower fixing element, an upper fixing element, a projection device, a transparent bottle, and an assembling element. The projection device is disposed inside the lower fixing element and the transparent bottle is disposed thereon and fixed by a positioning annulus on an inner surface of the lower fixing element. The assembling element has a depression surface atop to be engaged a positioning plate of the upper fixing element and an upper engaging space to mount on the transparent bottle. A spring is further disposed between the upper engaging space and the transparent bottle. Thereby the transparent bottle is able to display attractive visual effects by lighting projection and to be easily engaged and disengaged.

A device for attachment to a belt for holding an accessory having a base, a front surface and a back surface, the base having belt receiving slots and the front surface of said base having a right side and a left side wherein said left side of said base having a first retaining portion extending substantially perpendicularly to said front wall and said first retaining portion having a first sidewall extending therefrom substantially parallel to and spaced from said front surface and forming a first recess and said right side of said base having a second retaining portion extending substantially perpendicularly to said front wall and said second retaining portion having a second sidewall extending therefrom substantially parallel to and spaced from said front surface and forming a second recess and a release member formed as part of said base.

A disclosed lighting apparatus includes a light-diffusive plate having opposing first and second faces bounded by one or more sides. A first electrically conductive sheet is disposed on the first face of the light-diffusive plate, and an electrically insulative sheet is disposed on the first electrically conductive sheet. A second electrically conductive sheet is disposed on the electrically insulative sheet. A plurality of solid-state lighting (SSL) elements have light emitting portions that face a portion of the light-diffusive plate. The SSL elements are electrically coupled to the first electrically conductive sheet and to the second electrically conductive sheet.

Lighting fixtures are provided. In one example implementation, a lighting fixture can include a housing, one or more drivers, and means for securing the one or more drivers to the housing to decrease thermal resistance between one or more of the drivers and the housing. The lighting fixture can also include an LED system comprising a light engine having a plurality of LED devices. The plurality of LED devices can be arranged on an LED board of the light engine such that a first portion of the LED board has a first density of LED devices and a second portion of the LED board has a second density of LED devices. The first density can be different than the second density.

Lighting systems and devices include a light-transmissive tube and a light source assembly. The light-transmissive tube defines a cavity that extends along a longitudinal axis, at least a portion of the tube having an inner structured surface facing the cavity, and an outer structured surface facing away from the cavity. The light source assembly is disposed to inject light into the cavity, and includes one or more discrete light sources such as LED sources. The inner and outer structured surfaces of the tube are configured to direct a first portion of the injected light out of the tube through the outer structured surface and to direct a second portion of the injected light back into the cavity, such that a virtual filament, or pattern of virtual filaments, appears in the tube.

A system comprising track-mounted luminaires and track. In some embodiments, electrical power for illumination is accessed by a luminaire through electrified railing recessed within a relatively narrow slot of the track. In some embodiments, a mount is provided separately from and/or additional to the power slot; for example, a magnetic mount. Optionally luminaires are orientable to select a direction of illumination, while secured by the magnetic mount. The track is optionally mounted flush and/or recessed with a mounting surface such as a ceiling and/or wall. In some embodiments, a recessed surface of the track is formed with an arc. Optionally luminaires conform with the curvature of the arc. Additionally or alternatively, the track is at least partially masked and/or decorated, for example by plastering and/or a face plate.
