Abstract

The present disclosure provides a point-control lamp and a lamp string, wherein the point-control lamp includes a lighting component, a direct-insert LED support, and an injection-molded part. The direct-insert LED support includes a signal input part, a positive power connection part, and a negative power connection part. The lighting component includes a main control chip and multiple lighting chips. The lighting component is arranged inside the injection-molded part, and the direct-insert LED support passes through the injection-molded part and connects to the lighting component. The main control chip is electrically connected to the signal input part. The main control chip is also electrically connected to the positive power connection part, and the main control chip is also electrically connected to the negative power connection part. The lighting chips are electrically connected to the main control chip. The main control chip is configured to store a number address of the point-control lamp. Arranging a separate signal transmission line and matching with packaging addresses the issue of signal stability being affected by the power supply when the signal is transmitted through traditional power lines, thereby increasing the maximum number of lamps that can maintain stable signals, reducing costs, and improving user experience.
