A seamless lighting arrangement for a vehicle panel. The vehicle panel has an inside surface and an outside surface. The vehicle panel has a light aperture extending from the inside surface of the vehicle panel to the outside surface of the vehicle panel. Connected to the inside surface of the vehicle panel is a bracket. The seamless lighting arrangement further includes a lens with a bracket connection portion that connects to the bracket and a transmission portion positioned within the light aperture of the vehicle panel. The lens further includes a light unit fixedly connected to the lens. The light unit has a projector port for emitting light from a light source. The light transmission portion of the lens has a light input surface region formed on an inside surface of the lens and a light output surface region formed on an outside surface of the lens.

A main unit of a lighting device with expandable functionality. The main unit includes at least one light source, driver electronics, and a housing with an at least partially light-permeable housing wall. The main unit further includes a coupling element for forming a wireless coupling interface to an extension unit, wherein the coupling element is located within the housing and is designed such that the wireless coupling between the main unit and the extension unit through the partially light-permeable housing wall is carried out. Furthermore, an extension unit and a lighting device are provided.

A plant growth light and a plant growing shed, the plant growth light including a housing enclosing a chamber having an opening at least at one end; a heat dissipation member disposed within the housing and dividing the chamber into at least a heat dissipation member channel and a lighting channel; a light board disposed in the lighting channel and being thermally connected to the heat dissipation member; a fan disposed close to the opening and forcing an airflow to accelerate. The housing illuminated by the light board is translucent to enable light to irradiate plants to be supplemented with light located outside the housing, and the housing is provided with a plurality of air outlet holes spaced in an extension direction of the heat dissipation channel to enable the accelerated airflow to be blown to plants to be ventilated located outside the housing.

A fan bracket for attaching or detaching at least one fan comprising a frame, a plurality of positioning pins, a circuit board assembly, and a magnet is provided. The positioning pins disposed on the frame are inserted into a plurality of assembling holes of the fan respectively, wherein different housing parts of the fan are assembled to each other via screws locked in the assembling holes respectively. The circuit board assembly disposed in the frame has at least one first quick connector protruded out of the frame, wherein the first quick connector is mated to a second quick connector of the fan in a process of the fan assembling to the fan bracket structurally. The magnet disposed in the frame attracts to at least one magnetic conducting sheet of the fan.

A wall light fixture is provided, including a base, at least one lamp body, a driving circuit board, and a battery module. The at least one lamp body is disposed on the base, the driving circuit board is disposed in the base, and the driving circuit board is electrically connected to the at least one lamp body. The battery module is configured to supply power to the at least one lamp body. The base defines an accommodating cavity, the battery module is detachably disposed in the accommodating cavity. The base defines an accommodating cavity, the battery module is detachably disposed in the accommodating cavity. An access opening is defined at one side of the base, the access opening is communicated with the accommodating cavity for the battery module to be inserted into the accommodating cavity or pulled out of the accommodating cavity.
