In design, the built-in IC is a remarkable feature. The IC chip is closely integrated with the lamp bead, which realizes the intelligent control of the lamp bead. This integrated design effectively simplifies the external circuit, reduces the system complexity, and improves the overall stability and reliability. Built-in IC series lamp beads have excellent performance. It has accurate current control ability, which can ensure that each lamp bead can maintain stable and uniform brightness under different working conditions. This not only prolongs the service life of the lamp beads, but also makes the lighting effect more lasting and stable. The products are widely used in LED luminous full-color string, LED full-color module, LED magic color soft and hard light bar, LED guardrail tube, LED appearance, scene lighting, LED opposite screen, various electronic products, and electric equipment racing lights.
