Description

Technical Field

[0001] The utility model relates to the field of lighting, in particular to a light bulb. Background Art

[0002] Traditional light bulbs generally do not have dimming or color temperature adjustment functions, and their functions are single. In order to expand the scope of use, existing light bulbs have added dimming or color temperature adjustment functions. At present, the dimming or color temperature adjustment method is usually to set a switch adjustment part on the side of the lamp head. The switch adjustment part is inserted into the lamp head to turn the adjustment switch of the power supply control. The brightness or color temperature is adjusted by changing the adjustment switch position of the switch adjustment part. The switch adjustment part destroys the original structure of the lamp head of the light bulb and affects the appearance of the lamp body. Utility Model Content
