Description

Technical Field

[0001] The utility model relates to a lighting device, in particular to a bulb lamp. Background Art

[0002] LED bulbs are a common lighting source product. Traditional LED bulbs can only emit light of one color temperature, which is relatively simple. For this reason, many manufacturers have designed bulbs with adjustable color temperature. At least two LED lamp beads with different color temperatures are set on the light source board. The light temperature is adjusted by adjusting the light on and off of the lamp beads with different color temperatures through switches. For example, China with application number CN202022424590.4 discloses a lamp that uses a toggle switch to adjust the color temperature, including an outer decorative shell and a bulb shell. A first optoelectronic integrated board and a radiator are installed inside the outer decorative shell. The radiator is located above the first optoelectronic integrated board. A first toggle switch is installed on the side surface of the outer decorative shell, and a second toggle switch is installed on the side surface of the bulb shell. A second optoelectronic integrated board is installed inside the bulb shell. The utility model can form different logical arrangements and obtain different color temperatures by utilizing the mechanical characteristics of the patch toggle switch.

[0003] However, in the above patent document, the toggle handle of the toggle switch is exposed to the outside, which affects the overall aesthetics. In addition, since a switch hole needs to be opened on the lamp body, the overall structure of the lamp body will be destroyed, and the difficulty of mold opening will also be increased.

[0008] In a preferred embodiment: the rotating paddle and the metal rotating shell, and the metal rotating shell and the rotating switch are fixedly connected via cutout grooves.

[0009] In a preferred embodiment: an insulating shell is provided on the inner wall of the lamp holder, and a clearance opening is provided on the insulating shell at a position corresponding to the lower end of the lamp holder; one end of the rotating paddle passes through the clearance opening and cooperates with the insulating shell in a limiting manner opposite to the insertion direction.

[0010] In a preferred embodiment: the rotating paddle is provided with an inserting rib, the end of which protrudes radially outward to form a first limiting surface; the first limiting surface is limitedly matched with the inner wall of the lower end of the insulating shell against the insertion direction.

[0011] In a preferred embodiment: the inner wall of the upper end of the insulating shell extends radially inward to form a second limiting surface, and the upper surface of the driving circuit board is limitedly matched with the second limiting surface.

[0012] Compared with the prior art, the technical solution of the utility model has the following beneficial effects:
