After the film is installed in a placement groove reserved on the film plug-in, the film plug-in is plugged into the plug-in guide, the LED light source is a structure in which LED lamp beads are arranged on a substrate, and a light cup covering the LED lamp beads is fixed on the substrate, the LED light source is fixed at the bottom of the projection lamp cavity, and the bottom opening of the projection lamp cavity is blocked; the LED light source, the film and the focusing wheel cooperate for projection.
[0008] As an improvement, a self-locking switch is also included: the self-locking switch is a structure in which a C-shaped card sleeve is fixed on the right side of the pull-out block, the C-shaped card sleeve is an elastic structure, and a card pin is formed on the left side of the film insert to engage and fit with the C-shaped card sleeve. After the film insert is plugged into the insert guide rail, it can be firmly locked and fixed.
[0009] As an improvement, a heat sink is fixed on the lower side of the LED light source, which can provide an effective heat dissipation effect for the starry sky projection structure.
[0010] The advantages of the utility model compared with the prior art are:
[0011] When the utility model is in use, in addition to being able to provide a normal projection viewing experience, the user can also turn on the starry sky projection structure to allow it to project a starry sky effect, thereby allowing the experiencer to watch the movie in the environment and atmosphere of the starry sky projection, thereby improving the user's projection viewing experience.
