[0003] The electrode inside the lamp holder is directly electrically connected to the AC power supply provided by the power company. Since the voltage of the AC power source itself is large, the electrode and the lamp of the lamp are in the process of loading and unloading the lamp. When the electrodes in the seat are in contact, sparks may be generated or arcing may occur, causing the loader to be burnt or get an electric shock. [0004]

Secondly, in the conventional lamp holder, when the lamp tube is not mounted thereon (that is, when the lamp holder is unloaded), the voltage between the electrodes at both ends of the lamp holder is substantially equal to the voltage value of the AC power source provided by the power company, and therefore, when When people accidentally touch, there is a danger of electric shock.
