Among them, LED filament bulbs, compared with conventional SMD LED lamps, have the characteristics of full-circle light, high light efficiency, glass shell, etc., which are closer to the lighting experience of traditional incandescent lamps. In addition, compared with traditional incandescent lamps, their color temperature range is very large, almost multiple color temperatures can be achieved, and it is easy to mix colors, which has great development potential.

[0003] Existing LED filament bulbs use a dip switch to switch the color temperature. In order to cooperate with the dip switch, a mounting piece is set between the bulb shell and the lamp holder. The upper and lower ends of the mounting piece are connected to the bulb shell and the lamp holder respectively. The dip switch is set in the mounting piece. The mounting piece is provided with a dial hole. The dial hole and the dip switch are set correspondingly.
