New description: [New technology field] This creation is about the kind of T8 light-emitting diode ship f protection Wei, _ is a kind of use of at least - the rectification of the electric switch to form the power supply back side, bribe The circuit of the light source load of the τ8 light-emitting diode lamp. [Prior Art] According to the conventional LED light-emitting diode (LED, Light Emitting Di〇de) lamp, it is widely used in T8 daylight lamps, and it is a light source that replaces the conventional fluorescent fluorescent tube. In the design of the power connection, there is a clear and long-lost lack. As shown in the figure, the conventional T8 LED lamp tl is respectively provided at both ends - the connector 2, which is set in the connector 2 There is a pair of pins 3, which are correspondingly connected to the lamp tube connecting base 5 at both ends of a τ8 daylight lamp 4, so that the pin 3 can be connected to the AC mains power supply of the dingy 8 daylight lamp*, so that 8 lights are emitted. The pole lamp 丨 can be used to illuminate the mains power supply. However, in order to allow the two pins 3 of the two connectors 2 to be inserted into the lamp connector 5, it is known that the fluorescent tubes do not have left and right directions and the front and rear polarities respectively. Therefore, it is necessary to short-circuit the two pins 3 of each connector 2, so that 14 feet of the two-brain 2 pins 3 are connected in parallel to the end of the T8 wire 4 starter (STARTER) 6 So that the starter 6 will also generate an ENABLE action when the Ding 8 daylight lamp 4 is connected to the AC mains power supply, so that the circuit generates a high voltage surge wave to the T8 light emitting diode through the pins 3 of the two connectors 2 In the lamp i, but the T8 LED lamp 1 is designed internally, it is not an operation mode in which the fluorescent lamp is freely discharged by the heating of the gas. The high voltage surge will cause the T8 to emit light. The internal wiring of the polar body lamp fl is damaged or the performance of the line and the life of the LED component are reduced. In order to solve the T8 light-emitting diode lamp! The problem of generating two voltage dog waves by the start of the T8 daylight lamp 4 is 4 ^94665. The negative practice is that the starter 6 can only be removed from the T8 daylight lamp 4 by the user. Inadvertently, there is still a chance of damage to the T8 light-emitting diode lamp 1. If it is necessary to restore the conventional fluorescent tube, it is necessary to reinstall the emblem 6 to make the money and _; If you consider the spur wave or surge absorber inside the Τ8 LED lamp, you will make the ΙΈ 一 一 一 灯 1 成本 , , , , , , , , , , , , , , , 一 一 一 一 一 一 一 一 一 一 一 一 一.
