Detail
The two-wire breakpoint lighting solution mainly consists of the corresponding protocol chip, lamp beads and a few resistors and capacitors. It can be designed as single-color, cold and warm dual-color light source, three-color illusion point light source/ribbon, etc. according to actual needs. The breakpoint transmission method is our invention patent.
TM1934 is a single line return to 0 code protocol LED constant current driver IC, the chip provides three high-precision constant current output channels with voltage resistance up to 30V, the external controller only needs a single line to control the chip, dual-channel digital interface (DIN, FDIN) switch input to each other, through the line connection to achieve the breakpoint transfer function, one of the chip damage does not affect the normal work of the subsequent chips. Suitable for guardrail tube, point light source and other LED decorative products.
