Abstract
A light source device with a safety mechanism includes a wavelength converting device and a laser light source configured to provide a laser beam. The wavelength converting device includes a substrate facing toward the laser light source, an optical converting layer disposed on the substrate, and a safety examination layer disposed on one side of the optical converting layer. After the laser beam passes through the safety examination layer, the laser beam enters the optical converting layer. The safety examination layer includes a first conductive film arranged along a first direction and a second conductive film arranged along a second direction. The first conductive film and the second conductive film intersect each other.
