LIGHTING DEVICE

摘要

Disclosed is a light emitting device having a configuration that, when a magnitude of an input voltage is greater than a minimum light emitting voltage, all light emitting devices are turned on regardless of the magnitude of the voltage. As the magnitude of the voltage is smaller, the light emitting devices are connected in parallel. As the magnitude of the voltage is greater, the light emitting devices are serially connected.

1. A lighting device, comprising:
a light emitting unit comprising a current input terminal, a current output terminal, a current bypass output terminal, and a first light emitting group that emits light by a current inputted to the current input terminal; and a second light emitting group connected to receive at least part of a current outputted through the current output terminal, wherein the current output terminal selectively outputs the entirety of or part of a current inputted through the current input terminal, and wherein the current bypass output terminal outputs the rest of the entirety of the current other than the part of the current, when the current output terminal outputs the part of the current,.
