LED Beads
Keyword:
LED lamp beads should be capacitive and inductive loads:
In fact, both are not. The LED bead is a diode. It needs a positive conduction voltage to work, usually 2-3.5V. In addition, the current size can control the brightness of the LED bead. That is to say, LED lamp beads only convert electric energy into light energy.
8. The reason for the decline of LED light bead:
There are four reasons for the attenuation of low-power LED: First, the iron bracket has poor heat conduction. 2： Yellowing of epoxy resin. 3： The contact between chip and bracket is not close enough. 4： Chip attenuation is large. If it is white light, there is also the problem of phosphor attenuation
