Augmented Reality（AR）Head up display（HUD）By directly projecting important driving information into the driving field of view, the driving experience has been significantly optimized. In fighter jetsHUDIt is the outstanding application of such technology that displays key data in real-time within the pilot's field of view. In the field of automobiles,HUDPlacing graphic information directly in the driver's line of sight replaces basic warning sounds or symbols, enhancing the driver's ability to identify and respond to potential hazards. These graphics, as natural extensions of the real world, are not onlyHUDSupplement to information display. Solar irradianceAR HUDThe design presents a serious challenge due to its wide field of view, long virtual image distance, and vehicle sensor dataHUDReal time integration requirements for displays.

Long virtual image distance (exceeding)7m）And a wider field of view (at least horizontally)10Degree, vertical at least4This significantly increases the focus and heat of sunlight on the imaging panel. To prevent thermal damage,AR HUDThe design requires meticulous and detailed simulation of solar load to confirm its reliable operation. The following is a simulation of solar loadAR HUDThe key points to consider when designing impacts include the accuracy of the solar load model, the effect of off-axis solar irradiance, and the thermal effects of solar irradiance.

correctOptical interference light source simulatorThe angle, spectral and irradiance characteristics, as well as the precise spectral transmission curve of automotive optical components, are crucial. During the driving process, when the car turns or goes up and down hills, sunlight from different angles will enter the car, so simulating the incident sunlight within a certain angle range is crucial. The peak off-axis solar irradiance may be higher than the main ray level2.7Double, increase the heat load. If the system design does not consider the worst-case off-axis irradiance, there is a risk of damage to the imaging panel. The thermal effect of sunlight is also crucial, as our tests have shown,TFTThe temperature rise rate of the panel due to solar load isDLPTransmitting micro lens array diffuser screen used in technical systems6Twice.
