Abstract

The invention relates to the technical field of light source systems, in particular to a vehicle HUD light source system. The vehicle HUD light source system comprises an LED light source (1), light cups (2), a prism film (3), a light-reflecting cup (4), a liquid crystal display screen (5) and a fixed support (6), wherein the liquid crystal display screen (5) is installed at the front end of the fixed support (6); the LED light source (1) is installed at the rear end of the fixed support (6); a plurality of light cups (2) are arranged at the front side of the LED light source (1); the LED light source (1) is connected with the small-opening ends of the light cups (2); the large-opening ends of the light cups (2) are connected with the prism film (3); the liquid crystal display screen (5) is located at the front side of the prism film (3); the light-reflecting cup (4) is arranged between the prism film (3) and the liquid crystal display screen (5); the light-reflecting cup (4) is installed on the fixed support (6); the diameter of the light-reflecting cup (4) is gradually increased from rear to front; according to the vehicle HUD light source system disclosed by the invention, compared with the prior art, the optical efficiency is increased and the heating amount is greatly reduced through reducing the loss of a light, meanwhile, volume requirements on heat dissipation fins are reduced, and the small dimensions and low cost of the whole system are realized.

Description

[technical field] [0001] The invention relates to the technical field of light source systems, in particular to a vehicle HUD light source system. [Background technique] [0002] Since the aperture ratio (commonly known as the light transmittance) of the HUD display is very low, only 4%-7%, and then through the refraction of the multi-faceted mirror and the windshield, the final optical efficiency is only 10-20%; , but also consider the impact of strong sunlight on the display effect during daytime driving, so the brightness of the light source must be increased. The increase in the brightness of the light source will inevitably lead to an increase in heat, that is, the volume of the heat sink will increase, which will cause thermal damage to the display screen. Therefore, in the current situation, it is necessary to increase the effective utilization of the light source to achieve the balance of light intensity and heat. [utility model content] [0003] The purpose of t...
