LED lamp bead model and use parameters

When using LED lamp beads, we are mainly concerned about some main parameters. We can discuss it. Connecting all LED in series or in parallel not only limits the usage of LED, but also the load current of parallel LED is large, and the cost of the driver will also increase. The solution is to use the hybrid method, most of the current usage is the hybrid form....
