Description

Technical Field

[0001] This utility model belongs to the field of stage lighting technology, specifically relating to a projector. Background Technology

[0002] With technological advancements, stage lighting demands increasingly sophisticated projection effects, moving beyond simply pursuing variations in light and color to also seeking changes in projected patterns and overall effects. Currently, most stage lighting projectors on the market display static patterns, failing to meet the demands for optimal stage performance. While a few projectors can achieve dynamic effects, these rely on switching between different pattern sources, resulting in inconsistent and disjointed dynamic changes. Furthermore, different stage lights cannot effectively combine dynamic effects.

[0003] Therefore, it is necessary to provide a projector that can realize continuous dynamic projection of patterns, greatly enhance the projection effect of stage lights, have a wider range of applications, and can project more complex and richer dynamic patterns. Utility Model Content

[0004] The purpose of this invention is to provide a projector that addresses the shortcomings of existing stage lights in that they cannot continuously project dynamic patterns.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A projector is characterized in that it includes a main mounting frame, a source plate, and a motor; the main mounting frame has a projection hole; a dynamic source is fixed on the source plate, and the source plate is connected to the motor for transmission, so that the motor drives the source plate to move back and forth above the projection hole to project a dynamic pattern.

[0007] The present invention can be improved in the following ways: a guide member is fixed on the main fixing frame, and the film source support plate is provided with a guide groove. The film source support plate is fixed on the guide member by the guide groove, so that the film source support plate can move back and forth along the guide member.

[0008] In this utility model, the film source support plate is provided with two guide grooves, which are arranged in parallel; the film source support plate is fixed to two guide members by the two guide grooves.

[0009] Furthermore, the source plate is rectangular, and the dynamic source is fixed in the middle of the source plate.

[0010] In this invention, the sheet support plate is connected to the motor via a drive belt.

[0011] In some embodiments of this utility model, the film source support plate is provided in two sets, and correspondingly, the motor is provided in two sets, with each motor being connected to one film source support plate for transmission.

[0012] This invention can be further improved by including a Hall effect device, which is fixed on the main mounting frame. The Hall effect device is used to locate the initial position of the wafer support plate.

[0013] Furthermore, two Hall effect devices are provided.

[0014] This utility model has the following beneficial effects:

[0015] (1) The projector of this utility model is equipped with a source plate and a motor. The motor drives the source plate to move continuously, thereby dynamically projecting the static pattern on the dynamic source plate to form a continuous dynamic pattern effect.

[0016] (2) The projector of this utility model can combine two source plates to form a more dynamic pattern by overlapping the patterns on the two source plates; at the same time, it can also linearly combine the patterns of different stage lights, and the dynamic effect has high scalability and the pattern is richer.

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. Attached Figure Description

[0027] The technical solution of this utility model will be further described below with reference to specific embodiments, so that those skilled in the art can better understand and implement the technical solution of this utility model.

[0028] Example 1

[0029] like Figure 1-4 The projector shown includes a main mounting bracket 1, a source plate 2, and a motor 3.

[0030] The main mounting frame 1 has a projection hole 5 in the middle for light to pass through; a guide member 6 is fixedly connected to each of the front and rear sides of the projection hole 5. There is a source plate 2 on each side of the projection hole 5, and the source plate 2 has two symmetrical guide grooves 7. A dynamic source (not shown in the figure) is fixed between the two guide grooves 7 of the source plate 2. The source plate 2 is limited and fixed to the two guide members 6 by the guide grooves 7, allowing the source plate 2 to move back and forth along the guide members 6. The two source plates 2 are arranged side by side, and are located at different heights on the main mounting frame 1. During movement, they can be staggered and layered, thereby superimposing the patterns on the dynamic source on both plates to project more diverse patterns. Each source plate 2 is connected to a motor 3 via a connecting belt 8. The connecting belt 8 is fixed to the main frame 1 via guide wheels 9. The motor 3 provides power for the movement of the source plate 2, enabling it to move one source plate 2 left and right, thereby moving the dynamic source back and forth. When the pattern reaches above the projection hole 5, the pattern on the dynamic source is projected. Since the source plate 2 is in motion, a static pattern can be projected to form a dynamic pattern. In this embodiment, the connecting belt 8 is a temperature-resistant and wear-resistant steel wire rope, and the source plate 2 is fixed to the steel wire rope. The source plate 2 is rectangular, and the two sets of source plates 2 share two guide members 6. Two Hall effect devices 4 are also fixed on the main frame 1 to locate the initial position of the source plate 2, thereby better controlling the projection effect of the dynamic pattern.

[0031] Example 2

[0032] like Figure 5-8 The projector shown differs from the embodiment in that the setting position of the motor 3 is different and the transmission method of the connecting belt 8 is different. In this embodiment, the connecting belt 8 is a toothed belt. Correspondingly, the source plate 2 is connected to the connecting belt 8 through the toothed member 10, making the entire structure run more smoothly.

[0033] The above embodiments of this utility model are not intended to limit the scope of protection of this utility model. The implementation of this utility model is not limited thereto. All other modifications, substitutions or alterations made by those skilled in the art based on the above content of this utility model and in accordance with the common technical knowledge and conventional means in the art, without departing from the basic technical idea of ​​this utility model, shall fall within the scope of protection of this utility model.
