Abstract

A system of lighting for an artificial tree or other decoration that allows easy replacement of small sub-strings of luminaries. Each sub-string contains N luminaries, where N is an integer around 10, where the N luminaries are wired in series. Extender cables can be supplied that contain parallel splits so that the different sub-strings are operated in parallel. The extender cable can attach to a master power source that supplies the constant voltage needed to power each sub-string. The exact voltage is determined by the number N and by the voltage requirement for each of the luminaries. Each sub-string has a plug that mates with a receptacle on either an extender cable, or on the master power device. Single point failures only cause one sub-string to go dark. The physical arrangement with plugs and receptacles allows easy replacement of an individual sub-string that is dark because of a failed luminary.

Radially uniform spring-biased intra-pole plug connector and transformer

Abstract

A radially uniform spring-biased intra-pole plug connector and transformer outside the trunk configuration for an electric artificial tree is described. The radially uniform plug comprises a springed-tip and a prong, and allows the tree trunk segments to be connected at any point along their 360 degree circumference. The plug connector resembles the structure of a car cigarette lighter. A mold is used to sandwich the plug within the trunk. A plug portion of the plug connector is housed in one trunk segment, and a receptacle portion is housed in a different trunk segment, such that when the trunk segments are assembled, the plug is connected, illuminating the tree. The plug allows the electrical wiring to be hidden and housed within the trunk, providing safety, convenience to the user and giving the tree a cleaner appearance. The transformer outside the trunk configuration makes the trunk safer, more lightweight and less bulky.
