Abstract
An embodiment provides a beam projector module including: a light source configured to output light; a substrate configured to support the light source; an optical device configured to reduce the light in terms of intensity output to a predetermined space; a frame configured to separate the optical device from the light source by a predetermined distance; an optical substrate configured to attach the optical device thereto and to define a sealed space with the substrate and the frame, the sealed space having internal pressure lower than pressure outside the sealed space; a sensor configured to measure a state of the sealed space; and a processor configured to change an operation mode of the light source depending on a measured value of the sensor.
