Description

Technical Field

[0001] This utility model relates to the field of laser lighting technology, specifically to a star-track laser lighting fixture. Background Technology

[0002] A starry sky projector is a light fixture that projects a starry sky pattern into a dark environment. Utilizing high-definition optical lenses and advanced projection technology, it projects a beautiful starry sky pattern onto a wall or ceiling, creating a romantic and comfortable atmosphere. It can be used as an ambient light in homes, cars, scenic spots, and entertainment venues. However, existing starry sky projectors often only provide a dotted "starry sky" effect, lacking the striped "cloud" effect and the combined effect of a "nebula," resulting in a less than ideal effect. Utility Model Content

[0003] This invention provides a star-track laser light fixture, which solves the above-mentioned technical problems.

[0004] The solution to the above-mentioned technical problems provided by this utility model is as follows:

[0005] A star-track laser light fixture includes a base plate, a laser source, a first vertical grating plate, and a second vertical grating plate. The laser source is mounted on the base plate, and a convex reflector and a plane reflector are mounted on the base plate in front of the laser source. The laser beam emitted from the laser source is reflected sequentially by the plane reflector and the convex reflector before passing through the first vertical grating plate and the second vertical grating plate.

[0006] Based on the above technical solution, the present invention can be further improved as follows.

[0007] Furthermore, the angle between the first vertical grating sheet and the second vertical grating sheet can be adjusted as needed.

[0008] The beneficial effects of adopting the above-mentioned further solutions are:

[0009] The adjustable angle design allows users to fine-tune parameters such as the diffusion angle and scanning speed of the grating according to specific scenarios or creative needs, thereby creating a unique star trail effect. This personalized customization capability enhances the attractiveness and market competitiveness of the lighting fixtures.

[0010] Furthermore, the convex reflector and the flat reflector are positioned correspondingly.

[0011] The beneficial effects of adopting the above-mentioned further solutions are:

[0012] The convex and flat mirrors are positioned opposite each other to ensure that the light emitted from the laser source is reflected along a predetermined path when it passes through these two mirrors, reducing light loss, improving light utilization, and allowing more light to pass through the subsequent grating sheet to form a brighter and clearer light and shadow effect.

[0013] Furthermore, the laser beam emitted from the laser source is in a dot matrix pattern.

[0014] The beneficial effects of adopting the above-mentioned further solutions are:

[0015] The dot-matrix laser beam path can evenly distribute multiple light spots over a large area. The dot-matrix light spots can form a dynamic star trail effect by being scanned laterally by the first vertical grating plate and the second vertical grating plate.

[0016] The beneficial effects of this utility model are:

[0017] This lighting fixture, through a combination of a laser light source, a convex reflector, a flat reflector, and a first and a second vertical grating sheet, can transform a dot-matrix laser spot into a horizontally scanning grating, thus creating the visual effect of star trails. This unique light and shadow effect can bring a highly artistic and technological atmosphere to a space, making it suitable for various occasions such as exhibitions, commercial spaces, and entertainment venues, enhancing the overall visual appeal of the environment.

[0018] The angle between the first and second vertical grating plates in the lamp can be adjusted as needed. This means that users can freely adjust the shape and trajectory of the star trail according to different scene requirements and aesthetic preferences to achieve personalized light and shadow effects.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1 As shown, the embodiments provided by this utility model are as follows:

[0027] Example 1

[0028] A star trail laser light fixture includes a base plate 3, a laser source 4, a first vertical grating plate 6, and a second vertical grating plate 7. The laser source 4 is mounted on the base plate 3. The laser light path 1 emitted by the laser source 4 is dot-matrix shaped, which can evenly distribute multiple light spots over a large area. The dot-matrix light spots, when scanned laterally by the first vertical grating plate 6 and the second vertical grating plate 7, can form a dynamic star trail effect. A convex reflector 2 and a flat reflector 5 are mounted on the base plate 3 in front of the laser source 4. The positions of the convex reflector 2 and the flat reflector 5 are corresponding, ensuring that the light emitted by the laser source 4 follows a predetermined path when passing through these two mirrors. The laser beam from the laser source 4 is reflected sequentially by a plane mirror 5 and a convex mirror 2 before passing through a first vertical grating plate 6 and a second vertical grating plate 7. This process transforms the dotted light spots into horizontally scanning beams, creating a star trail effect. The angle between the first and second vertical grating plates 6 and 7 can be adjusted as needed. This adjustable angle design allows users to fine-tune parameters such as the diffusion angle and scanning speed of the grating according to specific scenes or creative needs, thus creating a unique star trail effect. This personalized customization capability enhances the attractiveness and market competitiveness of the lighting fixtures.

[0029] When using a star-track laser light fixture based on Embodiment 1:

[0030] The laser beam emitted by the laser source 4 is designed in a dot matrix shape, that is, multiple light spots are formed on a surface;

[0031] A grating is an optical element with regularly arranged fine structures etched on its surface. These structures can be linear, strip-shaped, or other geometric shapes, capable of diffracting and refracting incident light, causing the beam to deflect in a specific direction and angle. Vertical gratings have structures arranged vertically, therefore their main function is to influence the propagation and dispersion of the light beam in the horizontal direction.

[0032] When the lattice beam passes through the first vertical grating plate 6, each light spot in the beam is dispersed or diffracted by the vertical structure of the grating plate. This dispersion causes each light spot to expand into a short linear track on the horizontal plane, and these short linear tracks are arranged in the horizontal direction to form an expanded light spot area;

[0033] The beam, after being processed by the first vertical grating plate 6, continues its journey and then encounters the second vertical grating plate 7. The second grating plate also has a vertical structure, but its angle can be adjusted as needed. Due to the different relative positions and angles between the second and first grating plates, the beam will diffract and disperse again, further altering its propagation path. This secondary processing allows the beam to form more complex lateral expansion and scanning effects in space.

[0034] After being processed by two vertical grating plates, the light beam is no longer a dotted pattern, but rather a dotted pattern with a trajectory. Because the beam undergoes two diffraction and refraction processes between the two grating plates, each light spot moves along a specific path. Visually, this creates a continuous light trail, similar to the trails of stars in the night sky, producing a star trail effect.

[0035] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
