Beam projector module using laser

A beam projector module comprising:

• a cathode conductive pad that is made of a conductive material or coated with a conductive material and has one side surface, a part or the entirety of which is electrically connected to a cathode wire on a Printed Circuit Board (PCB) for supplying power;
• 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 electrically connected to an anode wire of the PCB through at least one electric wire;
• a diffuser configured to diffuse a light beam output from the light source;
• a frame surrounds the light source, and supports the diffuser so that the diffuser is spaced from the light source by a predetermined distance;
• and
• a transverse bar part that is coupled to the frame,
• wherein the transverse bar part is disposed between the electric wire and the PCB and cuts off the electric wire at the time of occurrence of a vibration or an external shock.
