LED lighting tube lights equivalent to the HF fluorescent tubes

摘要

The present invention relates to an LED light tube, to provide an LED light tube which has to be used in replacing the HF fluorescent lamp to the high frequency lighting fluorescent lamp. A high-frequency power source of about high-frequency lighting from fluorescent lamp electronic ballast of about 50KHz 200V is supplied to the electrodes 2 of the both ends. This power is one side of the sent to the semiconductor switch element 4 rectifier element 5 through the triac SSS, etc. with no gate, through the current control element of the inductor such as high-frequency power source on one side of 8 from the opposite side of the electrode 2 from the electronic ballast is sent to the rectifier element 5, the high-frequency power source is converted into direct current. The DC power supply is supplied to LED7 through the constant-current element 6 LED7 is illuminated. .BACKGROUND
