An elongated heatsink structure retaining single and/or bi-directional light sources that receive variable power input(s) through at least one endcap coupled to the elongated heatsink structure.

In embodiments of the present invention, a method and system is provided for commissioning improved intelligent, LED-based lighting systems. The LED based lighting systems may include fixtures with one or more LED light bars, integrated sensors, onboard intelligence to send and receive signals and control the LED light bars, and network connectivity to other fixtures.

A light fixture includes a housing, and a lighting module. The housing defines first and second portions. The second portion defines a window. The lighting module is at least partially disposed in the second portion. The lighting module includes a submount, a plurality of light emitting diodes, a lens cover, and an encapsulating material. The plurality of light emitting diodes is coupled with the submount and is configured to project light through the window. The lens cover includes an exterior surface and overlies the plurality of light emitting diodes and the submount such that the lens cover and the submount define an interior therebetween. The encapsulating material substantially fills the interior.

A film and television lamp is provided by embodiments of the present disclosure, comprising: a housing assembly, wherein the housing assembly is provided with a cavity, the housing assembly comprises a first housing, the first housing comprises a first ventilation area, a second ventilation area and shelter structure between the first ventilation area and the second ventilation area; a circuit board assembly, wherein the circuit board assembly is provided in the cavity and in correspondence with the shelter structure; a heat dissipating assembly, wherein the heat dissipating assembly is provided in the cavity, and the heat dissipating assembly comprises a first radiator and a second radiator, the first radiator is connected with the second radiator. The present disclosure aims to solve technical problems in the prior art that heat dissipation and waterproof in the film and television lamp cannot be both achieved.

An integrated-lighting-module may have a driver cap, a heat sink module, a LED light chip, an optical reflector, and a holder/trim. The driver cap may be configured to hold a driver within the driver cap to power the LED light chip. The driver cap may attach to a top of the heat sink module. The heat sink module may be finned at various locations. The holder may attach to the heat sink module with the optical reflector and the LED light chip disposed between elements of the holder and elements of the heat sink module. Trim, such as MR16 sized trim, a lamp, and/or a lens holder, may attach to bottom flanges of the holder. The integrated-lighting-module may be adjusted without interfering with the trim. The holder may be trim in some embodiments.

Provided is a heat dissipation structure and an illumination device which are capable of dissipating heat readily and efficiently. A heat dissipation structure 1 configured to release heat from a heat source 100 is provided with a plurality of heat reception/dissipation members 10 which have expanded graphite layers containing expanded graphite and which are spaced apart from each other; and a connection member 20 configured to connect the heat reception/dissipation members 10 together. The heat reception/dissipation members 10 each have the expanded graphite layer as the outermost layer and are disposed such that the expanded graphite layers face each other.

An LED light source apparatus includes a lamp housing, a lighting module, and a lens. The lamp housing has a first shell body, a second shell body, and a waterproof pad disposed between the first and second shell bodies. The first shell body and the second shell body are covered to each other. The second shell body has an opening. The waterproof pad is provided with a throughhole corresponding to the opening. A light guide flap is disposed on the perimeter of the opening of the second shell body. The lighting module is disposed inside the lamp housing corresponding to the opening. The lens is installed on a side of the lamp housing corresponding to the lighting module. Therefore, the components or the lighting module with a different power can be conveniently replaced by modules and thus the present invention has the flexibility in replacement and maintenance.

An LED module for a luminaire has a downwardly directed heat sink comprising cooling fins that extend rearward from the module's front end and downward from its top wall, which has a top face that abuts the underside of a luminaire carrier plate. A circuit board carrying at least one LED is mounted on the front face, and a prism is mounted to the heat sink over the LED(s). The front (light-emitting) face of the catadioptric prism has several prominent side-by-side sections which emit beam patterns that diverge laterally and overlap in a central region. A prominent full-width upper section on the front face emits a primarily downwardly directed beam pattern to help fill in dark spots.

A light fixture apparatus having an LED circuit board mounting platform and an LED driver housing configured to attach to the circuit board mounting platform to form a module which is attachable anywhere along a wiring rail platform.

A driving device according to an embodiment includes a supporting portion, an arm portion and a reinforced portion. The supporting portion includes an electrically-driven first drive source. The arm portion is supported by the supporting portion at one end portion in an extending direction and is, by the first drive source, rotatable about a first rotation axis that is along the extending direction, the arm portion including an electrically-driven second drive source. The reinforced portion is provided inside the arm portion and reinforces the arm portion. An object of operation is mounted on another end portion side of the arm portion and is rotatable about a second rotation axis intersecting the extending direction by the second drive source.
