LED Main Classification

Light-emitting diodes can also be divided into ordinary monochromatic light-emitting diodes, high-brightness light-emitting diodes, ultra-high-brightness light-emitting diodes, color-changing light-emitting diodes, flashing light-emitting diodes, voltage-controlled light-emitting diodes, infrared light-emitting diodes, and negative resistance light-emitting diodes.

There are two control modes for LEDs: constant current and constant voltage. There are multiple dimming methods, such as analog dimming and PWM dimming. Most LEDs use constant current control, which can keep the LED current stable and not easily affected. The change of VF can extend the service life of LED lamps.
