Embodiment 1

[0048] refer to figure 2 A vehicle-mounted projection system according to Embodiment 1 of the present application will be specifically described. figure 2 A schematic structural diagram of a vehicle-mounted projection system according to Embodiment 1 of the present application is shown.

[0049] Such as figure 2 As shown, in this exemplary embodiment, a high-brightness LED light source 110 emits a light beam for illumination, and the light beam first enters a light adjustment mechanism including a collimator lens 120 and a relay lens 130 . Wherein, the collimating lens 120 is used to collimate the light beam emitted from the high-brightness LED light source 110 and propagate along a straight line, and the relay lens 130 is used to shape the light beam to uniformly irradiate the subsequent dynamic image display device. However, the light adjustment mechanism is not limited to the combination of the collimator lens 120 and the relay lens 130 described above, as long as the ...

Embodiment 2

[0055] refer to image 3 A vehicle-mounted projection system according to Embodiment 2 of the present application will be specifically described. image 3 is a schematic configuration diagram showing a vehicle-mounted projection system according to Embodiment 2 of the present application.

[0056] Such as image 3 As shown, the high-brightness LED light source 210 emits a light beam for illumination, and the light beam first enters the light adjustment mechanism including the collimator lens 220 and the relay lens 230 . The collimator lens 220 and the relay lens 230 are sequentially arranged along the optical path direction of the light beam propagating. Wherein, the collimating lens 220 is used to collimate the light beam emitted from the high-brightness LED light source 210 and propagate along a straight line, and the relay lens 230 is used to shape the light beam to uniformly irradiate the dynamic image display device. However, the light adjustment mechanism is not limit...

Embodiment 3

[0063] refer to Figure 4 A vehicle-mounted projection system according to Embodiment 3 of the present application will be specifically described. Figure 4 is a schematic configuration diagram showing a vehicle-mounted projection system according to Embodiment 3 of the present application.

[0064] Such as Figure 4 As shown, a high-brightness LED light source 310 emits a light beam for illumination.

[0065] In this exemplary embodiment, a fly-eye lens 320 is used as the light adjustment mechanism. The fly-eye lens is formed by a series of small lenses, which converge each beam of parallel light (with uneven intensity distribution) emitted by the light source. Applying the double-row fly-eye lens array to the lighting system can obtain high light energy utilization efficiency and uniform lighting of a large area. Fly-eye lenses have broad application prospects in the fields of microdisplays and projection displays. The fly-eye lens 320 makes the light beam emitted from ...

Abstract

The present invention discloses a vehicle projection system. The vehicle projection system comprises an illumination module, a dynamic image display device and a projection module. The illumination module emits a light beam for illumination; the dynamic image display device can load information to be displayed, and the light beam can carry the information to be displayed after passing through thedynamic image display device; and the projection module can receive the light beam carrying the information to be displayed and can project the information to be displayed on a surface to be displayed. The vehicle projection system is close to miniaturization in structure, can project dynamic images, and good in imaging quality and high in resolution.

Description

technical field [0001] The present application relates to technical fields such as mechanical engineering and vehicle projection lighting, and more specifically relates to a micro-projection-based vehicle projection system. Background technique [0002] With the development of the automobile industry, the vehicle projection system has attracted more and more attention from the industry. For example, a vehicle-mounted projection system that has emerged in the automotive industry in recent years has the functions of lighting the floor and projecting the model or brand pattern of the car. It can project information such as the car logo on the ground. On the one hand, it can display the car brand On the other hand, it can play the role of lighting at night and reminding pedestrians and vehicles at the front and rear of the door to pay attention to safety. [0003] However, for the common vehicle-mounted projection system, the projection is based on the film, and since the proje...
