Abstract
Official abstract text for this publication.
A laser light source module includes a housing and a heat sink that is thermally connected to the housing. The housing includes a laser element that emits laser light, a laser holder that is made of metal to hold the laser element, a laser light receiving element that receives laser beam from the laser element, a mirror element that reflects the laser light to scan a screen, an optical element that is disposed on the optical axis of the laser light. The laser holder is thermally connected to the housing with a thermally conductive member. A protrusion is formed on the thermally conductive member. The protrusion and the springiness of the thermally conductive member are used to press the laser holder against the housing in the same direction as the direction of laser light emission.
