Title:
HEAD-UP DISPLAY
Document Type and Number:
WIPO Patent Application WO/2019/031519
Kind Code:
A1
Abstract:
This head-up display is applied to a moving body provided with: a windshield (3); an air conditioning unit (40) including a blowout opening portion (41a) for blowing out an airflow; and a blowout port (50) for blowing out the airflow from the blowout opening portion. The head-up display is provided with a light source (10) which emits display light for displaying information, and an optical path housing (20) forming an optical path (21) which causes the display light to propagate from the light source to the windshield. The display light that has passed along the optical path is projected onto the windshield, thereby displaying the information on the windshield. The head-up display is provided with an air conditioning duct (30) forming an airflow path which guides the airflow from the blowout opening portion to the blowout port. The light source is exposed within the airflow path of the air conditioning duct such that heat from the light source dissipates into the airflow path. The optical path housing and the air conditioning duct are configured in such a way that the airflow path and the optical path are separated by means of a mutually shared separating wall (32).
