Technical Field

[0001] This utility model relates to the field of projection lamp technology, specifically a projection lamp with an abyss mirror structure. Background Technology

[0002] A projector is a lighting device whose main function is to focus a light source through a lens onto an object or surface to create visual effects such as patterns or text. It contains one or more light sources and is usually equipped with an optical lens to adjust the imaging effect and light distribution. Projectors can be divided into various types, such as slide projectors, laser projectors, and LED projectors, and they are widely used in stage performances, commercial displays, home entertainment, and wall decoration.

[0003] While existing projectors provide users with visual enjoyment, their presentation is relatively simple, mainly limited to flat images or simple animation effects. Although some advanced projectors enhance the visual experience through color adjustment and dynamic layer overlay, these devices still lack an experience that can bring people a "deep abyss vision".

[0004] In view of this, the present invention solves the above-mentioned technical problems by proposing a projection lamp with an abyss mirror structure. Utility Model Content

[0005] To address the shortcomings of the aforementioned background technology, this utility model provides a technical solution for a projection lamp with an abyss mirror structure. By constructing a parallel reflection cavity with reflector a and reflector b, and combining it with the light path guidance of a pentagonal structure, the light from the LED light strip is reflected multiple times to form a hierarchical light source image with "decreasing brightness and reduced size". When observed through reflector b, it presents a "light tunnel with infinite depth" and a thousand-layer dynamic abyss vision.

The connecting column a and the connecting column b are respectively fixedly connected to the opposite surfaces of the projection lamp body a and the projection lamp body b. There are four connecting columns a and four connecting columns b, which are distributed in a cross pattern. The surface of the connecting column a is connected to the inner cavity of the connecting column b, so that the projection lamp body a and the projection lamp body b are connected.

[0012] As a preferred embodiment of this utility model, two snap-fit ​​posts are fixedly connected to the opposite surfaces of the projection lamp body a and the projection lamp body b. A housing is snapped into the inner cavity of each snap-fit ​​post. A partition is embedded in the inner cavity of the housing. A drive motor is fixedly connected to the bottom of the partition.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 1-4 As shown, a projection lamp with an abyss mirror structure includes a projection lamp body a1;

[0027] The projection lamp body a1 is connected to the projection lamp body b101 via a connecting structure;

[0028] Both the inner walls of the projection lamp body a1 and the projection lamp body b101 are equipped with abyss vision structures.

[0029] The abyss vision structure includes a reflector a2 embedded in the inner wall of the projection lamp body a1 and the projection lamp body b101. One end of the projection lamp body a1 and the projection lamp body b101 are fixedly connected to a mounting frame 201. An LED light strip 202 is fixedly connected to the inner wall of the mounting frame 201. A reflector b203 is embedded in the inner wall of the mounting frame 201. A certain distance is provided between the reflector a2 and the reflector b203. The LED light strip 202 is located between the reflector a2 and the reflector b203.

[0030] Reflector a is a total reflection mirror or a semi-transparent semi-reflective mirror, and reflector b is a semi-transparent semi-reflective mirror;

[0031] The connection structure includes connecting post a3 and connecting post b301. Connecting post a3 and connecting post b301 are fixedly connected to the opposite surfaces of the projector lamp body a1 and the projector lamp body b101, respectively. There are four connecting posts a3 and four connecting posts b301, which are distributed in a cross pattern. The surface of connecting post a3 is connected to the inner cavity of connecting post b301, so that the projector lamp body a1 and the projector lamp body b101 are connected.

[0032] Two snap-fit ​​posts 407 are fixedly connected to the opposite surfaces of the projector lamp body a1 and the projector lamp body b101. The inner cavity of each snap-fit ​​post 407 is connected to the housing 4. The inner cavity of the housing 4 is fitted with a partition 401. The bottom of the partition 401 is fixedly connected to a drive motor 402. The top of the partition 401 is fixedly connected to a projector lamp 403. The surface of the output shaft of the drive motor 402 is fitted with a lens 404. The surface of the housing 4 is provided with a slot 405. The inner cavity of the slot 405 is slidably connected to an insert 406. The insert 406 is located above the projector lamp 403 through the slot 405.

[0033] Connecting post a3 and connecting post b301 are interference fit, and the end of connecting post a3 is provided with a guide chamfer;

[0034] The projector lamp body a1, projector lamp body b101, reflector a2, mounting frame 201 and semi-reflector 203 are all in the shape of a pentagonal star. Reflector a2 and reflector b203 are acrylic reflector a and acrylic reflector b, respectively.

[0035] LED light strip 202 is a flexible LED light strip, which is fixed to the inner wall of mounting frame 201 by thermally conductive adhesive;

[0036] Both the edges of the projection lamp body a1 and the projection lamp body b101 are rounded.

[0037] Both reflectors a2 and b203 are glued to the inner wall of the projection lamp body a1, the projection lamp body b101 and the mounting frame 201 with UV-curing adhesive.

[0038] In use, the reflector a2 on the inner wall of the projection lamp body a1 and the reflector b203 in the end mounting frame 201 are arranged in parallel and maintain a distance to form a "reflection cavity". The reflector a2 can be a total reflection mirror or a semi-transparent semi-reflective mirror, and the reflector b203 is a semi-transparent semi-reflective mirror. The two mirrors work together to achieve the control of light reflection and transmission.

[0039] When a total reflection mirror is selected as the reflector a(2):

[0040] The total reflection mirror (reflector a2) completely reflects the incident light with high reflectivity (such as acrylic material, 100% reflectivity), ensuring the continuity of the optical path within the reflection cavity and preventing light from escaping from the reflector a side. The semi-transparent semi-reflective mirror (reflector b203) has a light transmittance of 30% to 50% (acrylic's semi-transparent characteristics), allowing some light to pass through while the remaining light is reflected back to reflector a2. After the LED light strip 202 is powered on and emits light, the light enters the reflection cavity from the side and reciprocates between reflector a2 and reflector b203. Reflection: Each time the light passes through mirror b203, some of it is transmitted through the mirror. The remaining light is reflected by mirror a2 and then returns to mirror b203. As the number of reflections increases, the transmitted light decreases in brightness and shrinks in size as the light path increases due to energy attenuation. When viewed through mirror b203, the multi-level transmitted light extends continuously along the depth direction. Combined with the pentagram structure mirror design, the reflected light propagates along the star-shaped path, enhancing the sense of spatial layering and creating a "light tunnel and a thousand-layer dynamic abyss visual effect".

[0041] When a semi-transparent, semi-reflective mirror is selected for reflector a2:

[0042] Both mirror a2 (a semi-transparent, semi-reflective mirror) and mirror b203 (a semi-transparent, semi-reflective mirror) possess reflection and transmission characteristics (e.g., mirror a2 has a reflectivity of 70%–80% and a transmittance of 20%–30%, while mirror b203 has a transmittance of 30%–50% and a reflectivity of 50%–70%). The light distribution is controlled by the difference in reflectivity. After light enters the reflection cavity, it is reflected back and forth between mirror a2 and mirror b203: mirror a2 reflects most of the light back to mirror b203, with only a small amount of light transmitted (reducing light on the non-observation side). (Linear loss); Reflector b203 transmits some light and reflects the remaining light to reflector a2. After multiple reflections, the transmitted light still maintains the distribution pattern of decreasing brightness and shrinking size levels. Because the reflectivity of reflector a2 is higher than its transmittance, the light is mainly constrained within the reflection cavity to form a stable reflection path, ensuring that the transmitted light on the reflector b203 side can form a continuous and deep "light layer". With the guiding effect of the pentagram structure, when observed through reflector b203, a clear "light tunnel and thousand-layer dynamic abyss vision" effect can still be presented.

[0043] Projector lamp body a1 and projector lamp body b101 are fixed to housing 4 by snap-fit ​​post 407, and the housing is divided into upper and lower cavities by partition plate 401:

[0044] The output shaft of the drive motor 402 in the lower cavity of the housing 4 is coaxially fitted with a lens 404. When the drive motor 402 rotates, it drives the lens 404 to rotate synchronously.

[0045] The projection lamp 403 in the upper cavity of the housing 4 emits light vertically upwards, and the insert 406 (with surface etched pattern) is inserted into the slot 405 on the side wall of the housing 4, located directly above the projection lamp 403.

[0046] The parallel light emitted by the projector lamp 403 first passes through the insert 406 and is modulated into "pattern light" by the pattern;

[0047] The drive motor 402 drives the lens 404 to rotate, so that the refraction angle of the "pattern light" changes in a circular motion as the lens 404 rotates.

[0048] The "pattern light" modulated by the rotating lens 404 is projected vertically upwards onto the target surface of the ceiling. The pattern rotates synchronously around the center as the lens 404 rotates (e.g., if the motor speed is 30r / min, the pattern rotates 30 times per second), achieving a dynamic light and shadow effect.

[0049] Projector lamp body a1 and projector lamp body b101 are connected by an interference fit through connecting post a3 and connecting post b301.

[0050] Reflector a2 and reflector b203 are attached to the inner wall of the main body with UV adhesive to ensure the mirror surface is flat and maintain optical path stability;

[0051] The flexible LED light strip 202 is fixed to the mounting frame 201 with thermally conductive adhesive, which not only ensures that the light is incident from the side, but also helps to dissipate heat and extend the life of the light strip.

[0052] The rounded corners of the projector lamp body a1 and projector lamp body b101 prevent bumps and damage, and improve product safety.
