An electronic module group can include an electronic module including a first housing defining a housing cavity; a power supply driving module positioned within the housing cavity; and a first concentric terminal connected in electrical communication with the power supply driving module by a first wire and a second wire; and a second concentric terminal rotatably connected in electrical communication with the first concentric terminal, the second concentric terminal configured to transmit power to the first concentric terminal.

A lighting apparatus includes a driver configured to convert external power to a driving current, a light source connector with top and bottom portions separated by a distance, and a light source provided on a light source plate including a conductive patch. The light source plate is held between the top portion and the bottom portion, such that the driving current is supplied to the light source plate by the conductive path routed via the light source connector.

Methods and apparatus for illuminating decorations according to various aspects of the present invention may comprise a light source and a diffuser. A connector may connect the light source to the decoration. A reflector may reflect light from the light source towards an anticipated observer.

Wireless power transmission is used in conjunction with lighting, such as a light emitting diode (LED) bulb or lighting fixture that uses existing electrical wiring infrastructure. For instance, a lighting device is provided such that a wireless power transmitter is coupled to receive electrical operating power via the lighting device when the lighting device is coupled to electrical wiring infrastructure.

The LED luminaire is constructed with an LED/driver printed circuit board mounted directly on a floor of the heat sink assembly. By mounting the LED/driver printed circuit board directly in and on the heat sink assembly, the heat imposed on the LED/driver printed circuit board during use in a canopy hood over a cooking surface is transferred directly to the heat sink assembly for dissipation.

An electronic module can include a first housing defining a threaded bore and a shaft; a power supply driving module positioned within the first housing; a speaker positioned within the first housing, the speaker connected in electrical communication with the power supply driving module; a first concentric terminal connected in electrical communication with the power supply driving module, the first concentric terminal extending at least partially through the shaft, the first concentric terminal configured to rotatably connect in electrical communication with a second concentric terminal to supply power to the power supply driving module; and an auxiliary concentric terminal connected in electrical communication with the first concentric terminal, the auxiliary concentric terminal positioned at least partially within the threaded bore to define a power receptacle, the power receptacle configured to connect with and supply power to a second electronic module.

A lamp module group includes an LED lamp board, a power supply driving module, a concentric male terminal, and a first housing, which can achieve the purposes of heat conduction and heat dissipation, waterproofing, and rotational coaxial connection power extraction. A waterproof rubber ring is squeezed by the first housing causing a second housing where the concentric male terminal and the concentric female terminal is located, achieving the purpose of capable of achieving waterproofing between the first housing and the second housing. The first housing and the second housing are connected into one body by a thread, which may conduct the heat of the power supply driving module and the LED lamp board, thereby achieving the purpose of dissipating the heat of the power supply driving module and the LED lamp board.

Provided is a support system for replacing a linear fluorescent lamp with a light emitting diode (LED) module. The support system includes an elongated support member having one or more channel structures extending along substantially an entire length of the elongated support member. One or more ends of the elongated support member are configured for engagement with a socket. The support system includes at least one LED module mounted in mechanical engagement with the one or more channel structures by a fastening mechanism. The at least one LED module is positionable along a portion of the length of the channel structure.

Embodiments may utilize a series of exposed fins, which increase the surface area of the heat sink creating additional air flow. As hotter air rises within the system, cooler is drawn into the heatsink. The fins may be exposed on both sides of the longitudinal axis, allowing cooler air to be drawn towards the longitudinal axis above the heatsink and flow upward. This process may cool the fins. Additionally, the spacing between the fins may have to be wide enough to allow for air to freely enter the heatsink.
