An illuminable decoration comprises at least two trunk sections, each trunk section includes a hollow tube and a cable assembly coupled to each trunk section. Each cable assembly comprises a first modular electrical connector end that has an inner socket and an outer plug that circumscribes the inner socket. Further, each cable assembly comprises a second modular electrical connector end that has an inner plug and an outer socket that circumscribes the inner plug. A first electrical wire electrically couples between the inner socket of the first modular electrical connector and the inner plug of the second modular electrical connector. Also, a second electrical wire electrically couples between the outer plug of the first modular electrical connector and the outer socket of the second modular electrical connector. When two trunk sections are assembled together end-to-end, the trunk sections are mechanically and electrically coupled to form a modular electrical distribution system.

An external connected lamp holder has a first lamp holder, the first lamp holder is provided with a first socket matched with a lamp body, the lamp body has a first driving circuit board, the external connected lamp holder further includes a first female plug assembly. The external connected lamp holder, interconnected lamp holder, driving circuit board and lamp of the embodiments realize the installation of the lamp holder and the driving circuit board through plug-in electrical connection, instead of being welded together. This construction reduces the requirements of product precision, tooling precision and assembly precision in the automated production process, and it reduces the cost of automated manufacturing and the loss in the production process of products.

Disclosed herein are examples of a heating apparatus. In some embodiments, the heating apparatus is a battery powered heating apparatus suitable for burning or vaporizing a vaporizable material, such as an oil, wax, or liquid that when vaporized may be inhaled by a user. The heating apparatus includes a deployable element including a resistive element. In some embodiments, the heating apparatus has variable heat settings for the resistive element, controllable by the user through a user input (e.g., a button). In some embodiments, an indicator provides output communication to the user. The heating apparatus may include a power supply such as a rechargeable battery to supply power to the resistive element.

A semiconductor lamp (1) comprises a housing (2) in which a driver (3) is accommodated and at least one contact pin (6) protruding from the housing (2) outwards, wherein the contact pin (6) is tubular and riveted to the housing (2) and the driver (3) is connected to the contact pin (6) via an electrically conductive connection element (12) which is inserted into a cavity (13) of the contact pin (6). A method serves for producing a semiconductor lamp (1), wherein at least one tubular contact pin (6) is inserted into a feedthrough (5) of a housing (2) from outside till the contact pin (6) abuts the housing (2), the contact pin (6) is next riveted with the housing (2) on the inside and a driver (3) is inserted into the housing (2), whereby an electrically conductive connection element (12) is inserted into the contact pin (6). The invention is particularly applicable to LED retrofit lamps for replacing bipin halogen lamps, in particular MR16 lamps.

The invention relates to a power adapter comprising a first prong (12) rotatable between a stowed configuration and a deployed configuration; and a second prong (13,14) rotatable in an opposing direction between a stowed configuration and a deployed configuration. A deployment mechanism associated with the first and second prongs (12,13, 14) causes their movement between the stowed and the deployed configurations. The deployment mechanism comprises a cam (see FIG. 10) coupled to at least one of the first and second prongs (12,13, 14) and arranged to act on the other prong such that movement of the cam translates to rotation of the prongs. It will be appreciated that the invention provides for a collapsible power adapter which is smaller, more user-friendly and cost effective that conventional power adapters.

A power transfer system to facilitate the transfer of electrical power between tree trunk sections of an artificial tree is disclosed. The power transfer system can advantageously enable neighboring tree trunk sections to be electrically connected without the need to rotationally align the tree trunk sections. Power distribution subsystems can be disposed within the trunk sections. The power distribution subsystems can comprise a male end, a female end, or both. The male ends can have prongs and the female ends can have voids. The prongs can be inserted into the voids to electrically connect the power distribution subsystems of neighboring tree trunk sections. In some embodiments, the prongs and voids are designed so that the prongs of one power distribution subsystem can engage the voids of another power distribution subsystem without the need to rotationally align the tree trunk sections.
