Title: Innovations by John Louis Janning in the Lighting Industry
Introduction
John Louis Janning is an influential inventor based in Dayton, OH, renowned for his significant contributions to the field of lighting technology. With a remarkable portfolio of 59 patents, he has developed innovative solutions that enhance the functionality and efficiency of LED lighting systems, particularly for decorative purposes.
Latest Patents
Among his latest inventions, Janning has created a revolutionary Christmas tree equipped with DC outlets for powering LED light strings. This artificial tree utilizes substantially unfiltered, full wave rectified pulsating DC voltage to supply multiple female outlets on its trunk. Additionally, he introduced a power distribution strip that can be mounted on the tree, facilitating the convenience of connecting 'naked' LED light strings, which lack female end connector plugs or power conversion circuitry. These innovative designs ensure that the LED string lights, powered by full wave rectified voltage, maintain brightness and operability even if individual LEDs fail.
Another notable invention by Janning is the low-cost LED light string designed for pre-lit Christmas trees. This series-wired LED light string consists of multiple LEDs linked in series with a current-limiting resistor. A unique feature of this design includes a resistive component that shunts failed LEDs, allowing the remaining LEDs in the string to stay illuminated. This advancement not only promotes durability but also maintains an aesthetic appeal in festive settings during the holiday season.
