| titleOfInvention | Surge voltage reduction device of LED bulb |
| abstract | In the surge voltage reduction device of an LED bulb according to the present invention, in the surge voltage reduction device of an LED (Light emitting diode) bulb having an AC filter unit and an AC / DC conversion unit, a DC current applied from the AC / DC conversion unit Is connected to the parallel of DC current, but the cathode part is connected to the + part of the DC current and the anode part is connected to the negative part of the DC current in a transient voltage suppression (TVS) diode. With Diode; A resistance 2 configured at the front of the momentary voltage suppression diode and connected in series with the anode of the AC / DC converter; A surge voltage attenuating unit configured at the rear of the instantaneous voltage suppressing diode and configured to have resistors 3 connected in parallel to the positive and negative poles of the AC / DC converter; By reducing the primary overcurrent in the transient voltage suppression diode and bypassing the current that was not attenuated in the transient voltage suppression diode in resistor 3 to the cathode, the surge voltage is reduced twice to further stabilize the lighting of the LED bulb. In addition, the use of the instantaneous voltage suppression diode enables the suppression of surges with a high instantaneous current capacity and the fast switching speed. |
