Abstract: A light emitting circuit is provided. The light emitting circuit may include a first light emitting diode (LED) group to which LEDs are connected, and a second LED group to which LEDs are connected. A resistive load is serially connected to the first LED group to control a current with respect to the first LED group, and a capacitive load is serially connected to the second LED group to control a current with respect to the second LED group.
