PROBLEM TO BE SOLVED: To provide a head-up display for a vehicle capable of cooling a light source and efficiently dissolving dew condensation produced on a cooled translucent window while preventing dew condensation from occurring on a light source.SOLUTION: A head-up display (hereinafter, HUD) for a vehicle reflects light 2021 to a wind shield and causes a passenger to visualize a virtual image. The HUD includes a closed housing 201, a light source 202, a blower fan 203, a peltier element 204 and a translucent window 206. The light source 202 applies light 2021. The peltier element 204 cools the light source 202. The translucent window 206 transmits the light 2021 applied from the light source 202 toward the outside of the housing 201 from the inside of the housing 201. The light source 202 is arranged on a path through which wind generated by the blower fan 203 passes from the blower fan 203 to the translucent window 206.SELECTED DRAWING: Figure 2 |
