Claim Text:
1. A lighting device comprising: a light-emitting unit comprising a current input node, a current output node, a current bypass output node, and a first light-emitting group for emitting light due to a current input to the current input node; a second light-emitting group connected to receive a current output from the current output node; and a flicker controller provided between the current input node and the current bypass output node to turn off the first and second light-emitting groups when a voltage input to the current input node is equal to or lower than a predetermined voltage, wherein the current output node is configured to selectively output a whole or a part of a current input through the current input node, and wherein the current bypass output node is configured to output a remaining part of the current input through the current input node, when the current output node outputs the part of the current.
