AI Technical Summary

Technical Problem

Conventional automobile projection lights provide monotonous and uninteresting light and shadow images, lacking dynamic change.

Method used

A projection module with two projection units and a substrate unit, each with a projection tube and lens group, projects shifted or complementary images using micro-image light-transmitting pieces, controlled by a light source controller to asynchronously change brightness, creating a dynamically changing light and shadow effect.

Benefits of technology

The module projects continuously and dynamically changing light and shadow images, enhancing visual interest and engagement.

Abstract

The present invention provides a projection module that projects a dynamically changing light and shadow image onto a target area on the ground. [Solution] The present invention includes a projection device 10. The projection device includes a first projection unit 11 and a second projection unit 12 arranged in parallel adjacent to each other, and a substrate unit 13 provided on one side of the first projection unit and the second projection unit. The first projection unit and the second projection unit each have projection tubes 111 and 121, respectively. A lens group 112 and a micro-image light-transmitting piece 113 are provided inside each projection tube. The two micro-image light-transmitting pieces each have either the same but shifted image or symmetrical and complementary images. At least one light-emitting member 132 is provided on the substrate unit for introducing a light source into the first projection tube and the second projection tube.
