In a mounted position of the lamp shade (5) and the lamp (3), the main surface (24) of the cooling structure (21) adjoins the main heat dissipating surface (15) of the heat sink area (13). The invention further relates to a lamp and a lamp shade of said lighting device kit of parts.

A lighting fixture for a suspended ceiling including a grid of rails and hub forming an opening in the suspended ceiling has a housing with a mounting clip operable to toollessly mount to a vertical portion of a rail from above with a cam to resiliently expand the mounting clip laterally during mounting of the housing onto the rail, a light unit support connected to the housing and operable to toollessly mount to the hub, from above, and a light unit operable to toollessly mount to the light unit support, through the hub, from below the suspended ceiling.

A lighting assembly comprises a linearly extending luminaire having an electronic circuit board, an inner lens assembly attached to the forward facing surface of the electronic circuit board, the inner lens including an array of focused light sources, an outer lens disposed over the inner lens assembly, and a heatsink extending along the length of the linearly extending luminaire. A bracket is pivotally attached to the linearly extending luminaire, the bracket having an axis of rotation around a horizontal axis, whereby the linearly extending luminaire is separately rotatable along a horizontal axis relative to the elevated structure. The bracket also has an axis of rotation around a vertical axis, whereby the linearly extending luminaire is separately rotatable along a vertical axis relative to the elevated structure.

The present invention relates to a bulb structure, which comprises a bulb base, a pole member, a transmission base, and a plurality of lamp leaves. One end of the pole member is disposed at the bulb base. The transmission base is disposed at the other end of the pole member. The plurality of lamp leaves are disposed pivotally surrounding the transmission base and located surrounding the pole member. The plurality of lamp leaves pivot on the transmission base and move away from the pole member. The bulb structure according to the present invention includes two lighting patterns. The lamp leaves may spread or close. Thereby, different lighting ranges may be provided.

A doubly-sealed waterproof floodlight includes a heat dissipating portion, a lighting portion coupled to the bottom end of the heat dissipating portion, and a cover filled and coated with a sealing material, doubly-sealed, and integrally coupled to the heat dissipating portion. The heat dissipating portion includes a sealing portion formed on a side end of the heat dissipation portion, coated with the sealing material, and coupled to the cover. The cover includes a coupling portion formed on the top end of a side surface thereof. The coupling portion includes a sealing groove into which sealing material is filled for adhering and coupling the heat dissipating portion, a protruding support potion extending from the sealing groove, and a bottom surface portion which is flatly formed at a position lower than the protruding support portion, and in which the sealing material coated on the sealing portion is filled.

An angle adjustment device of an embodiment includes a first rotational unit and a spring member. The first rotational unit is supported by a frame body, and rotationally moves around a first rotating shaft that passes through the frame body and that is disposed along an opening surface of the frame body, by a driving force of a driving source with an object to be operated. The spring member urges the first rotational unit in a single direction of a rotational direction.

Some embodiments of the present disclosure provide a plant lamp. The plant lamp may include one or more light-emitting units and a lamp holder. Each of the one or more light-emitting units may include a light-emitting side and a non-light-emitting side oppositely disposed. The one or more light-emitting units may be mounted on the lamp holder. The plant lamp may further include one or more heat dissipation units located on the non-light-emitting side of at least one of the one or more light-emitting units, connected to the at least one light-emitting unit, and configured for heat dissipation of the at least one light-emitting unit.
