[0043] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments:

[0044] like Figure 1-4 As shown, a dynamic meteor shower effect lighting fixture includes a housing assembly 1 and a light source assembly 40. The light source assembly 40 is disposed inside the housing assembly 1. The light source assembly 40 includes a frame 2 connected to the housing assembly 1, and a laser light source 3, a first effect assembly 4, a second effect assembly 5 and a lens assembly 6 arranged sequentially along the light emission direction of the light source.

[0045] A reciprocating drive mechanism 7 is provided between the first effect component 4 and the frame 2. The first effect component 4 is used to decompose the laser beam emitted by the laser source 3 into multiple beams.

[0046] The reciprocating drive mechanism 7 is used to drive the first effect component 4 to move left and right back and forth relative to the second effect component 5 without completely leaving the area where the light source optical axis coincides.

[0047] The second effect component 5 is rotatably connected to the frame 2. The second effect component 5 is used to form multiple beams into multiple long strips of light of different lengths. A rotation drive mechanism 8 connected to the frame 2 is provided on one side of the second effect component 5. The rotation drive mechanism 8 is used to drive the second effect component 5 to rotate around the light output axis.

[0048] The lens assembly 6 is disposed on the light outlet of the housing assembly 1.

[0049] In this embodiment, by setting the first effect component 4 and the second effect component 5, the laser beam emitted by the laser source 3 is decomposed into multiple beams after passing through the first effect component 4, and then the multiple beams are formed into multiple strips of light of different lengths after passing through the second effect component 5.

[0050] By setting the reciprocating drive mechanism 7, the first effect component 4 is moved back and forth in the area where the light source optical axis coincides, so that the laser beam has different projection angles on the cylindrical mirror, thereby projecting a dynamic light and shadow effect like a meteor shower.

[0051] By rotating the drive mechanism 8, the second effect component 5 is driven to rotate around the light output axis, thereby projecting a dynamic light and shadow effect of a meteor shower that can flow and the direction of meteor sliding can be changed. Combined with the control of the on / off state of the laser light source 3, the lamp can project a dynamic light and shadow effect of a meteor shower streaking across the sky.

[0052] Compared with existing digital projector projection methods, the above structure has the advantages of low cost, small size, wide applicability, and excellent projection effect.

[0053] In this embodiment, a control module 9 is also provided in the light source assembly 40. The control module 9 is electrically connected to the laser light source 3, the first effect assembly 4, and the second effect assembly 5. Different dynamic meteor shower effects are achieved by controlling the on / off frequency of the laser light source 3 through the program built into the control module 9.

The first lens holder 41 is connected to the frame 2 through a reciprocating drive mechanism 7.

[0055] In this embodiment, the first effect lens 42 is fixedly disposed on the first light-transmitting hole 41a of the first lens holder 41, and the reciprocating drive mechanism 7 drives the first effect lens 42 to reciprocate by driving the first lens holder 41.

[0056] Furthermore, such as Figure 2 , 4 As shown, in order to decompose the laser beam into multiple beams, the first effect lens 42 is a multifaceted prism or diffraction sheet.

[0057] In this embodiment, under the action of the reciprocating drive mechanism 7, the position of multiple beams projected onto the multifaceted prism is changed, so that the multiple beams have different projection angles on the cylindrical mirror, thereby projecting a dynamic light and shadow effect like a meteor shower.

[0058] Furthermore, such as Figure 2 , 4 As shown, the second effect component 5 includes a second lens holder 51 rotatably connected to the frame 2. A second light-transmitting hole 51a is provided on the area of ​​the second lens holder 51 that coincides with the optical axis of the light source. A second effect lens 52 that does not completely cover the second light-transmitting hole 51a is provided on the second lens holder 51.

[0059] In this embodiment, the second effect lens 52 is disposed on the second light-transmitting hole 51a of the second lens holder 51, and the rotation drive mechanism 8 drives the second effect lens 52 to rotate by driving the second lens holder 51.

[0060] Furthermore, such as Figure 2 , 4 As shown, in order to make multiple beams present a long strip of light spot projection effect; the second effect lens 52 is a cylindrical lens.

[0061] In this embodiment, under the action of the rotary drive mechanism 8, the dynamic light and shadow effect flowing like a meteor shower can be transformed into a multi-dynamic light and shadow effect of a meteor shower that can flow and whose meteor sliding direction can be changed.

[0062] Furthermore, such as Figure 4 As shown, the reciprocating drive mechanism 7 includes a reciprocating drive assembly 71, a guide rod 72, a sliding connector 73, and a connecting seat 74;

[0063] At least two guide rods 72 are provided, and both ends of the guide rods 72 are connected to the frame 2 through connecting seats 74;

[0065] The reciprocating drive assembly 71 is used to drive the sliding connector 73 to move left and right along the guide rod 72.

[0066] In this embodiment, the first lens holder 41 can move horizontally relative to the frame 2 along the guide rod 72 via the slider connector. Under the action of the reciprocating drive assembly 71, the sliding connector 73 is driven to drive the first effect assembly 4 to move reciprocally relative to the laser beam.

[0067] The above structure improves the smoothness of movement and connection stability of the first effect component 4 by employing a structural design with at least two guide rods 72 and sliding connectors 73.

[0070] The first driving gear 712 is connected to the driving end of the reciprocating drive motor 711, and the driven gear 713 is rotatably connected to the connecting seat 74 away from the reciprocating drive motor 711 via a rotating shaft.

[0071] The reciprocating drive motor 711 is fixedly connected to the frame 2.

[0072] In this embodiment, a synchronous belt drive structure is adopted. The movement of the first synchronous belt 714 drives the sliding connector 73 to move back and forth, which has the characteristics of high driving efficiency, smooth operation, low noise and low maintenance cost.

[0077] The rotary drive motor 81 is located on one side of the second lens holder 51 and is fixedly connected to the frame 2.

[0078] In this embodiment, the rotary drive motor 81 drives the second lens holder 51 to rotate via the second synchronous belt 83, thereby realizing the rotation control of the cylindrical mirror. By adopting the bearing 10 and synchronous belt drive structure design, it has the characteristics of stable operation, high drive efficiency, low noise and low maintenance cost.

[0079] Furthermore, such as Figure 3 As shown, the outer casing assembly 1 includes an outer casing body 11 and an upper cover 12;
