LED ring lamp tube with rotatable electrode and color temperature switching function

Abstract

This invention provides a rotatable electrode LED ring lamp with color temperature switching function, comprising a ring body, a light-emitting module, and a rotatable connecting module. The ring body has a mounting notch at a specific position on its circumference for the rotatable connecting module to be pivotally mounted therein. The rotatable connecting module has a base and electrode pins, which can reciprocate relative to the ring body in a circumferential direction, allowing the electrode pins to be independently adjusted in position without affecting the light emission direction of the light-emitting diode. This allows the user to first maintain the light-emitting surface facing downwards for optimal illumination during installation, and then individually rotate the electrode to align with the socket for insertion, solving the problem of the light-emitting surface shifting due to the directional nature of conventional LED ring lamps. Furthermore, the ring body has a toggle switch electrically connected to the internal driver circuit board, allowing for switching between different color temperature outputs according to user needs. This enables the same model of lamp to support multiple color temperature specifications, effectively reducing the manufacturer's inventory management burden.

Claims
