Abstract

In a color head-up display, in particular for vehicles, in which the light from a light source (2) is transmitted through an at least partially light-transmitting display (3) and can be projected onto a windshield, a multiplicity of red, blue and green light-emitting diodes are arranged without packaging on a common support, and that a heat-dissipating device for cooling the light-emitting diodes is present.
