Abstract
The invention discloses a light emitting diode module with controllable luminosity, comprising a light emitting diode (LED) chip, a first switching unit, and a processor. The LED chip is electrically connected to a protective resistor, and the protective resistor is provided to avoid the LED chip from being burned. The first switching unit is electrically connected to a first switching resistor, and the first switching unit and the first switching resistor are in parallel to the protective resistor. The processor is provided to receive a switching signal and is electrically connected to the first switching unit, and the processor controls the first switching unit to be in a connection status or in an open status according to the switching signal, thus changing the total resistance to control the luminosity of the LED.
