Abstract

An indoor-outdoor projector has a housing, a slide holder and a projection lens assembly mounted on the housing, and an enhancer and a lighting device mounted in the housing. The enhancer has a mounting seat, a motor mounted on the mounting seat, and a refractive lens attached to a driving shaft of the motor and facing the projection lens assembly. The lighting device has a lighting end that can emit light. A slide with an image is inserted in the slide holder. The motor drives the refractive lens to rotate. The lighting device emits the light to pass through the rotating refractive lens, the slide, and the projection lens assembly to project a projection on a screen and to form dynamic lighting variations.
