A lighting apparatus is provided with a first housing assembly formed from a thermally conductive material and a second housing assembly formed of a thermally conductive material. At least one electrical component is positioned within the first housing assembly and the at least one electrical component is in thermally conductive contact with the first housing assembly. At least one light source is in thermally conductive contact with the second housing assembly. The second housing assembly is not in thermally conductive contact with the first housing assembly, such that thermal energy from the first housing assembly does not directly transfer to the second housing assembly.

The present invention provides a lighting device in which a planar light-emitting panel is supported by, and can be easily attached to and detached from, a support member. The support member has a support side engagement part and covers a large part of a feeding wiring line. The lighting panel has a planar light-emitting panel and a mounting member. The planar light-emitting panel is attachable to the mounting member and has a panel side engagement part on its rear surface. The mounting member is fixable to the support member, and has first and second attaching side engagement parts. The first attaching side engagement part can engage the support side engagement part in a direction substantially orthogonal to the support member at a position overlapping with the planar light-emitting panel. The second attaching side engagement part can engage the panel side engagement part in the orthogonal direction.

A ceiling suspension, including a first member, including physical and electrical connectors for being physically and electrically fixed to the ceiling, a second member, including physical and electrical connectors, for being physically and electrically connected to an electrical appliance, where the first and second members include complementary electrical connectors, being configured for electrically connecting one another upon completing horizontal sliding of the second member in relation to the first member being fixed to the ceiling, and where the first and second members include complementary physical connectors, being configured for supporting the second member by the first member upon completing the horizontal sliding of the second member.

A lighting system has a set of linear lighting elements and a set of suspension elements. Each suspension element comprises an upper fixing part and a lower connection part facing downwardly for making electrical and mechanical connection to an upward facing connector on a top face of an end of a linear lighting element. This enables a simple a push fit connection of the lighting elements to the suspension elements, after they have been suspended from a support structure above them.

The invention relates to a combined ceiling fan and light fixture, wherein the roots of the plurality of blades of the ceiling fan are respectively fixedly connected to a plurality of rotating components correspondingly arranged on the impeller. Each rotating component comprises a synchronous wheel, and all synchronous wheels are distributed on the bottom of the impeller with the wheel center of the impeller as the array center. Any two adjacent synchronous wheels are connected to each other by a swinging rod so that all the synchronous wheels move in the same direction with the corresponding blades. At least one swinging rod is connected with a spring for pulling the swinging rod back in the opposite direction of the centrifugal force of the blade to drive all the blades to be synchronously folded on the top of the impeller when the motor stops. The blade retraction mechanism of the invention has the advantages of high transmission precision, good operational stability, low noise and low cost.

A lighting assembly is provided that includes a light fixture in combination with a support grid such as a drop ceiling t-bar. The light fixture can be configured to use a t-bar as the main form of support. The light fixture can be push-fit onto a t-bar or use a clip to join two or more portions of the light fixture to an installed t-bar. Once attached to the T-bar, the light fixture itself can provides support for a ceiling tile. Various embodiments are provided which achieve a variety of light distributions useful in typical illumination applications. Both recessed and suspended fixture types are achieved in various embodiments which are particularly well suited for LED lighting.

An optical lens and optical lighting system comprising the optical lens, the optical lens comprising a top surface and a bottom surface, one of the top surface and bottom surface having a substantially v-shaped indent, and at least one of the top surface and the bottom surface comprising a plurality of prisms. The optical lighting system comprises an assembly for receiving the optical lens, the assembly comprising a fixture body for releasably securing the optical lens, one or more LED boards, each comprising one or more LED lights, wherein the plurality of prisms are configured to direct light from the one or more LED lights in both an upward and downward distribution simultaneously.

A light cover assembling structure has a light housing, a mounting sleeve, a light-emitting element, a transparent light cover, and a supporting cover. The mounting sleeve has an inner end mounted in the light housing and an outer end extending out of the light housing. An inner surface of the light housing and an outer surface of the mounting sleeve form an assembling space. The transparent light cover is mounted on the outer end of the mounting sleeve. The supporting cover is mounted on the outer end of the mounting sleeve, and has a first supporting side wall formed circumferentially and abutting the transparent light cover. The first supporting side wall of the supporting cover supports the transparent light cover such that the transparent light cover is firmly mounted on the mounting sleeve.

A modular troffer-style fixture particularly well-suited for use with solid state light sources. The fixture comprises a reflector that includes parallel rails running along its length, providing a mount mechanism and structural support. An exposed heat sink is disposed proximate to the reflector. The portion of the heat sink facing the reflector functions as a mount surface for the light sources. The heat sink is hollow through the center in the longitudinal direction. The hollow portion defines a conduit through which electrical conductors can be run to power light emitters. One or more light sources disposed along the heat sink mount surface emit light toward the reflector where it can be mixed and/or shaped before it is emitted from the troffer as useful light. End caps are arranged at both ends of the reflector and heat sink, allowing for the easy connection of multiple units in a serial arrangement.
