    Abstract: PURPOSE: A method for sensing degradation in a lighting device and a lighting device using the same are provided to uniformly maintain the brightness of light generated in a light emitting part by controlling a driving signal applied to a light emitting diode by using light detected in a sensor unit. CONSTITUTION: An initial drive signal is generated(S10). Light is generated from an organic light emitting diode by using the initial drive signal(S20). A part of the generated light is received and sensing information is generated(S30). A compensation signal is generated by comparing the sensing information with reference information corresponding to the initial drive signal(S40). The compensated drive signal is generated by using the compensation signal(S50).
