An LED projection lighting fixture comprises a main body (1), a power supply apparatus, an LED lighting assembly (3) and a convex lens (5). The power supply apparatus is arranged in the main body (1), the LED lighting assembly (3) is arranged in front of the main body (1), and the LED lighting assembly (3) is electrically connected with the power supply apparatus through a circuit board. The convex lens (5) is arranged in front of the LED lighting assembly (3) and located on the optical axis of the LED lighting assembly (3). The convex lens (5) and the LED lighting assembly (3) can move forwards and backwards relative to each other. The distance between the LED lighting assembly (3) and the convex lens (5) is varied in the range of 0~2 times of the focus length of the convex lens (5). A light-transmissive image and writing film or slice (4) is arranged between the LED lighting assembly (3) and the convex lens (5), and the convex lens (5) can be moved forwards and backwards relative to the image and writing film or slice (4). The LED projection lighting fixture can achieve the lighting requirement and also can switch to the function of image projection, and a combination of a product with lighting function and a product with image projection function can be obtained, which enables the distance between the LED lighting assembly (3) and the convex lens (5) continuously varying in the range of 0~2 times of the focus length of the convex lens (5). |
