[0032] In an embodiment of the utility model, the PCBA is connected to the film by stacking through the bracket, wherein a first preset number of light sources and a first preset number of collimators are installed on the PCBA, and the first preset number can be set based on experience or a specific application scenario. In the embodiment of the utility model, the value of the first preset number is not specifically limited. Preferably, the first preset number can be 12, the light source is an LED light source, and the first preset number of collimators constitute a collimator group.

[0033] Furthermore, there is a corresponding relationship between the light source and the collimator, and each light source has a corresponding collimator. The installation position of the light source on the PCBA will affect the installation position of the collimator. The principle of selecting the installation position is that the light emitted by the light source emits parallel light through the collimator.

[0034] In the embodiment of the utility model, the film sheet is stacked with the pressure plate, wherein a first preset number of patterns are arranged on the film sheet, and preferably, the film sheet is provided with a first preset number of partitions, and a pattern is arranged for each partition. Preferably, the first preset number of partitions can be divided by average distribution or other preferred methods, which is not specifically limited in the embodiment of the utility model.

However, the film sheet must be provided with a first preset pattern, and each pattern has a corresponding relationship with a light source and a collimator, that is, each pattern has a light source and a collimator corresponding thereto, therefore, the setting position of the image on the film sheet depends on the installation position of the light source and the collimator, and the setting principle is: the light emitted by the light source emits parallel light through the collimator, and the parallel light is irradiated onto the corresponding pattern.

[0035] In the embodiment of the utility model, the projection lens is fixed on the pressure plate, and is used to project the corresponding pattern on the film to a preset position, wherein the preset position can be the ground, the wall, the projection board or other preferred positions, which are not specifically limited in the embodiment of the utility model. The light emitted by the light source is parallelized through the collimator, and the parallelized light is irradiated onto the corresponding pattern, and the image is projected to the preset position based on the projection lens.

[0036] In the embodiment of the utility model, Figure 1-2 As shown, the controller is plugged into the PCBA to control the opening or closing of the corresponding light source.

[0038] The second control module is used to control the optical projection system to perform the second projection effect. The second projection effect is: the multiple light paths in the optical projection system include at least two dynamic light paths. When the optical projection system is in operation, one of the dynamic light paths is used as a background light path to mainly provide auxiliary lighting and dynamic background functions. The light source is always bright and does not require additional control. It only responds to the switch and sleep wake-up protocol. Other dynamic light paths provide dynamic projection content, including: breathing, stroboscopic, bright and dark light source actions. The complete response time must be controlled within 1ms to ensure the realization of high dynamic and flicker-free dynamic effects.
