Abstract
A rotary image projector includes a lamp shade, a power board, a driver, and a projection module. The power board is mounted to the lamp shade. The driver is disposed in the lamp shade and electrically connected to the power board. The projection module is driven to rotate by the driver and has a luminous element, a collective lens, and at least two projection assemblies. The luminous element is electrically connected to the power board. The collective lens is spaced apart from the luminous element. Each one of the at least two projection assemblies is disposed on one of two sides of the collective lens away from the luminous element and has a positioning sleeve, a film, and at least one imaging lens. The film is mounted to the positioning sleeve. The at least one imaging lens is mounted to the positioning sleeve.
Claims14
A rotary image projector comprising:
- a lamp shade;
- a power board mounted to the lamp shade;
- a driver disposed in the lamp shade, electrically connected to the power board, and having
- a driving shaft;
- and
- a projection module mounted to the driving shaft of the driver, driven to rotate by the driver, and having
- a luminous element electrically connected to the power board;
- a collective lens spaced apart from the luminous element;
- and
- at least two projection assemblies disposed on one of two sides of the collective lens away from the luminous element, spaced apart from each other, and each one of the at least two projection assemblies having
- a positioning sleeve disposed on one of the two sides of the collective lens away from the luminous element;
- a film mounted to the positioning sleeve;
- and
- at least one imaging lens mounted to the positioning sleeve and disposed on one of two sides of the film away from the luminous element;
- wherein light emitted by the luminous element travels through the film and the at least one imaging lens of each one of the at least two projection assemblies to form an image, and the images formed rotate about a center since the at least two projection assemblies are driven to rotate by the driver.
