Abstract
Disclosed is an LED bulb having many advantages over previous bulbs. The bulb is designed with ease of fabrication and low cost in mind. A main support is made of chromed copper, used for both its reflectivity, its readily availability, and its relative low cost. A collection of bright LEDs are electrically coupled to a driving circuit formed on a board that is housed within the main support. The LEDs are mounted on a circuit board flexible enough to form into a desired shape while rigid enough to withstand normal movements. The LED circuit board includes multiple polished or shiny areas, also called lands or panels made to reflect light away from the bulb. The panels are electrically insulated from the operating circuit and prevent injury should the bulb be broken and the components be touched, even while operating.
