[0026] The present invention will be further described below in conjunction with the accompanying drawings. It should be noted that this embodiment is based on the technical solution and provides a detailed implementation method and specific operation process, but the protection scope of the present invention is not limited to this embodiment.

[0027] This embodiment provides a projection lamp with a replaceable grating sheet, such as Figure 1-8 As shown, it includes a housing 1, a laser module 2, a grating module 3 and a control board 4. The laser module 2, the grating module 3 and the control board 4 are all arranged in the housing 1, and the grating module 3 is arranged in front of the laser module 2.

[0028] like Figure 3-4As shown, the grating module 3 includes a motor 5, a gear set, a magnetic seat 6, a magnet 7, an iron sheet 8, an iron sheet fixing seat 9, a tray 10, a grating 11 and a grating fixing seat 12; the gear set includes a driving wheel 13 and a driven wheel 14 that are meshed with each other, the driving wheel 13 and the output shaft of the motor 5 are coaxially fixed, and the driven wheel 14 is coaxially fixed to the magnetic seat 6; the magnet 7 is fixed to the magnetic seat 6, the iron sheet 8 is fixed to the iron sheet fixing seat 9, and the iron sheet 8 and the magnet 7 are magnetically attracted; the grating 11 is detachably fixed to the grating fixing seat 12; the grating fixing seat 12 and the iron sheet fixing seat 9 are fixedly connected and then installed. It is installed on the inner ring of the tray 10 and can rotate axially within the inner ring of the tray 10; the outer shell 1 is provided with a tray inlet and outlet 15, a part of the tray 10 extends from the tray inlet and outlet 15 to the outside of the outer shell 1, and the tray 10 can enter and exit the outer shell 1 from the tray inlet and outlet 15; the magnetic seat 6, iron sheet 8, iron sheet fixing seat 9 and grating fixing seat 12 are all provided with light holes corresponding to the laser module 2, and the grating 11 corresponds to the light through holes of the grating fixing seat 12; the front side of the outer shell 1 is provided with an exit hole 16 corresponding to the grating 11; the control board 4 is controlled and connected to the motor 5 and the laser module 2.

[0029] It should be noted that the grating of the present invention is a sheet-like structure. In order to further realize the projection of diversified patterns, that is, to integrate different patterns into the same grating, the grating of the present invention can be divided into several areas, and then different patterns are set in different areas. In this way, the grating can have different patterns at the same time, and these patterns are similar to Figures 9 to 17 Of course, the number of equally divided regions depends on the size of the grating.

[0030] During operation, the control panel 4 is used to control the start-up of the motor 5 and the laser module 2. After the motor 5 is started, its output shaft drives the driving wheel 13 to rotate axially, and the driving wheel 13 further drives the driven wheel 14 together with the magnetic seat 6 to rotate axially. Since the magnetic seat 6 is fixed by the magnet 7 and the iron sheet 8, and the iron sheet fixing seat 9 is fixed to the grating fixing seat 12, when the magnetic seat 6 rotates axially, it will drive the iron sheet 8, the iron sheet fixing seat 9, the grating 11 and the grating fixing seat 12 to rotate together. At this time, the laser light emitted by the laser module 2 passes through the light holes of the magnetic seat 6, the iron sheet 8, the iron sheet fixing seat 9 and the grating fixing seat 12, and further passes through the grating 11 and is emitted from the front side of the housing 1. The projection pattern effect formed corresponds to the design pattern effect on the grating. When the projection pattern effect needs to be changed, the tray 10 is pulled toward the outside of the housing 1 to separate the magnet 7 and the iron sheet 8. The tray 10, together with the iron sheet fixing seat 9 and the grating fixing seat 12, as well as the iron sheet 8 fixed on the iron sheet fixing seat 9 and the grating 11 fixed on the grating fixing seat 12 are also pulled out. At this time, the original grating 11 can be removed from the grating fixing seat 12, replaced with a new grating 11, and then the tray 10 is reinserted into the interior of the housing 1 through the tray inlet and outlet 15 to complete the replacement of the grating. The pattern effect on the grating can be designed according to needs and preferences, and a variety of projection pattern effects can be achieved by replacing the grating, such as Figure 9-17 shown.

[0031] In this embodiment, if Figure 5-6 As shown, the laser module 2 includes multiple laser lamps 16 of different colors and a module bracket 17. The inner cavity of the module bracket 17 is provided with a mounting groove 18, and the multiple laser lamps 16 of different colors are inserted into the mounting groove 18; the control board 4 controls the laser lamps 16 connected to the multiple different colors.

[0032] In this embodiment, the laser module includes three laser lamps 16 , so the inner cavity of the module bracket 17 is provided with three mounting slots 18 , and each laser lamp 16 is inserted into each mounting slot 18 .

[0033] In practical applications, laser lights of different colors can be added according to different needs, so that different light effect combinations can be formed, further increasing the diversity of the utility model.

[0034] Furthermore, in this embodiment, if Figure 1As shown, the housing 1 is provided with an inner cover 19, and the module bracket 17 is fixed within the inner cover 19. The front side of the inner cover 19 is provided with a light hole. The magnetic base 6 is located in front of the inner cover 19, and the light hole of the magnetic base 6 is coaxial with the light hole of the inner cover 19. The output end of the laser lamp 16 is opposite the light hole of the inner cover 19. In addition to fixing the laser module, the inner cover also prevents light from diverging.

[0035] In this embodiment, the magnet 7 is fixed to the front side of the magnetic base 6.
