Abstract: The present disclosure provides a beam projector module including: a PCB on which a cathode wire and an anode wire are positioned; a conductive pad that is made of a conductive material or coated with a conductive material and has one side surface; a first frame that is made of a non-conductive material and has one side surface which is in contact with the PCB; a light source having a cathode electrode and an anode electrode, the cathode electrode being in contact with the other side surface of the conductive pad; the anode electrode being connected to the anode wire through at least one electric wire passing through the opening; a diffuser configured to diffuse a light beam output from the light source; and a second frame configured to support the diffuser so that the diffuser is spaced from the light source by a predetermined distance.

Abstract: An embodiment provides a beam projector module that includes: 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 space the optical device apart from the light source by a predetermined distance, the frame forming a closed space with the substrate and the optical device; a temperature sensor configured to measure a temperature of the frame; and a processor configured to control an output of the light source. The processor is configured to operate the light source in an eye-safety mode when a temperature drop rate of the frame exceeds a reference value.
