Abstract
Disclosed are a laser light source device for a head-up display and a head-up display system using the same, the laser light source device for the head-up display including a plurality of light sources which emit laser light and a condensing unit which condenses the laser light emitted from the light sources, is connected to an image forming unit that generates an image for displaying information on a vehicle operation using the laser light, and provides the condensed laser light to the image forming unit. The laser light source device for the head-up display according to the present disclosure and the head-up display system using the same have advantages that optical alignment is not easily destroyed even under harsh operating environment such as a vehicle where considerable vibration and temperature change are introduced, because the whole part of the condensing unit is optically connected by the optical fibers with a high stability on the contrary to a conventional bulk-optic based system.
