In the present invention, the wavelength of the light irradiated from the light source unit is sensed, and when light of a wavelength harmful to the human body is unintentionally irradiated, the light source unit is turned off so that the light harmful to the human body is not irradiated. In addition, a lamp device for a vehicle in which lighting control of the light source unit is performed accurately by minimizing the occurrence of errors due to external factors when the light irradiated from the light source unit is detected is introduced. |
