LED LIGHTING EQUIPMENT USING ELECTRONIC BALLASTS AND ITS MANUFACTURE METHOD
摘要
A light emitting equipment capable of using an electronic ballast for an existing fluorescent lamp and a method for manufacturing the same are provided to improve a cost-down effect by using a driver to limit waveform rectification and current. A driving unit(120) rectifies a high frequency waveform inputted by an electronic ballast for a fluorescent lamp and performs a voltage drop. One or more light emitting diodes(100) are arranged on an upper side of the driving unit. An electric signal, which is driven by an LED driving voltage and current from the driving unit, is input into a light emitting diode array section(110).
