Abstract
An LED illumination device includes a circuit substrate, a bridge rectifier, a current-limiting chip, a resistance switching module and an LED group. The bridge rectifier is disposed on the circuit substrate and electrically connected to the circuit substrate. The current-limiting chip is disposed on the circuit substrate and electrically connected to the circuit substrate. The resistance switching module is disposed on the circuit substrate and electrically connected to the circuit substrate. The LED group includes a plurality of LED chips disposed on the circuit substrate and electrically connected to the circuit substrate. The bridge rectifier, the current-limiting chip, the resistance switching module and the LED group are electrically connected with each other. The resistance switching module includes a plurality of resistance switches and a plurality of resistor elements respectively corresponding to the resistance switches, and each of the resistance switches includes a physical switching key that is exposed.
