They can target the tonality of different spaces and project diverse light and shadow effects in the environment through changes in color and pattern, thereby bringing a unique visual experience and allowing people to have a good sensory experience when entering the space.
[0003] The projection lamp includes a shell, a light-emitting unit, a lens element and a projection sheet. The light-emitting unit is arranged in the shell, the lens element is arranged between the shell and the light-emitting unit, and the projection sheet is arranged between the light-emitting unit and the lens element, and can be set to different shapes or patterns according to needs. The light-emitting unit can emit light and pass through the projection sheet, and then enter the lens element to form refraction, and then the shape or pattern on the projection sheet is projected into the external environment through the shell, and a large-area light and shadow effect is generated, thereby enhancing the overall atmosphere of the field.
[0004] The light and shadow or pattern projected by the projection lamp is all static, and the projected light and shadow are mostly in the form of dots, textures or patterns. The visual effect presented is relatively static and monotonous. For places that need to boost the atmosphere, such as festivals, performances or banquets, it is difficult to create a joyful and lively atmosphere in line with the nature of the activities, so that the effect of livening up the atmosphere cannot be effectively achieved, thereby reducing the participants' sense of integration into the activities and bringing a poor experience. Therefore, there is still a need for further improvement. Summary of the Invention
[0005] The technical problem to be solved by the present invention is that the light and shadow effects projected by current projection lamps are relatively static and monotonous, and cannot effectively liven up the atmosphere of a venue.
[0006] The technical solution of the present invention is: To achieve the above-mentioned purpose, the projection lamp of the present invention comprises: a base; A main body is pivotally mounted on the top of the base and has a projection side. An assembly space is formed inside the main body with an opening toward the projection side. a cover body, which is provided on the projecting side of the main body and is capable of closing the assembly space; A driving assembly, which is disposed on the body and located in the assembly space; a lens assembly located in the assembly space and capable of being connected to the drive assembly and driven by the drive assembly to rotate, wherein the inner wall of the lens assembly is formed with a plurality of adjacently arranged optical refractive structures; a fixing seat, which is disposed on the body and located in the assembly space and can extend into the interior of the lens assembly; and A light emitting element is arranged on the fixing seat and located in the lens assembly. The light emitting element can emit light toward the projection side and can project a plurality of strip light beams through the optical refraction structure of the lens assembly and the cover.
[0007] The projector lamp of the present invention can be used to project light and shadow effects over a large area. Specifically, the projector lamp of the present invention can emit light through the light-emitting element and inject it into the lens assembly. The light can be refracted by the optical refractive structures distributed on the inner wall of the lens assembly. In addition, the lens assembly can be driven to rotate around the light-emitting element, so that the relative angle between each optical refractive structure and the light-emitting element continuously changes. At the same time, the refraction angle of the light also changes, thereby projecting the multiple strip-shaped light beams and the light and shadow effects that move in an infinite cycle, forming a dynamic visual experience, helping to create a joyful and lively atmosphere, and effectively livening up the atmosphere of the venue.

[0019] The following is a detailed description of the technical means used by the present invention to achieve the intended purpose of the invention, with reference to the drawings and preferred embodiments of the present invention.
[0020] See also Figures 1 to 3 , which is a preferred embodiment of the projection lamp of the present invention, includes a base 10, a body 20, a cover 30, a driving assembly 40, a lens assembly 50, a fixing base 60 and a light-emitting element 70.
[0021] like Figure 1 and Figure 2 As shown, the main body 20 is pivotally mounted on the top of the base 10 and has a projection side 21 . An assembly space 22 with an opening toward the projection side 21 is formed inside the main body 20 .
[0022] like Figure 1 and Figure 2 As shown, the cover 30 is disposed on the projection side 21 of the main body 20 and is capable of enclosing the assembly space 22 .
[0023] like Figure 2 and Figure 3 As shown, the driving assembly 40 is disposed in the body 20 and located in the assembly space 22 .
[0024] like Figure 2 and Figure 3 As shown, the lens assembly 50 is located in the assembly space 22 and can be connected to the driving assembly 40 and driven by the driving assembly 40 to rotate. The inner wall of the lens assembly 50 is formed with a plurality of adjacently arranged optical refractive structures 51.
[0025] like Figure 3 and Figure 4 As shown, the fixing seat 60 is disposed on the body 20 and located in the assembly space 22 , and can extend into the interior of the lens assembly 50 .
[0026] like Figure 3 、 Figure 4 and Figure 11 As shown, the light emitting element 70 is disposed on the fixing seat 60 and is located in the lens assembly 50 . The light emitting element 70 can emit light toward the projection side 21 and can project a plurality of strip light beams 80 through the optical refractive structure 51 of the lens assembly 50 and the cover 30 .
[0027] like Figures 4 to 7As shown, a mating portion 52 and a connecting portion 53 are respectively formed on opposite sides of the lens assembly 50, and the driving assembly 40 has a rotating portion 41. The rotating portion 41 can be passed through the connecting portion 53 and corresponds to the shape of the connecting portion 53. The mating portion 52 surrounds the fixing seat 60, and a limiting portion 61 is formed on the outer ring wall of the fixing seat 60. The limiting portion 61 is located on the outside of the lens assembly 50 and can abut the mating portion 52 of the lens assembly 50.
[0028] like Figure 3 As shown, the lens assembly 50 includes two lens housings 54, which can be assembled together to form a spherical shape. The multiple optical refractive structures 51 are arc-shaped and are arranged adjacent to each other along the inner walls of the two lens housings 54. The width of each optical refractive structure 51 gradually decreases from the center position toward the two sides of the lens housing 54 at the corresponding position. The two opposite sides of the assembled two lens housings 54 respectively form the matching portion 52 and the connecting portion 53; wherein, each lens housing 54 includes fifteen optical refractive structures 51.
[0029] like Figure 3 and Figure 4 As shown, the light emitting element 70 includes a substrate 71 and at least one LED unit 72. The substrate 71 is disposed on the fixing base 60. The at least one LED unit 72 is disposed on the substrate 71 and is an RGB three-color lamp, a single-color lamp, or a self-changing color lamp.
[0030] like Figure 8 and Figure 9 As shown, the base 10 includes a base body 11, a main tripod 12 and two auxiliary tripods 13. The main tripod 12 is pivotally mounted on the base body 11. The two auxiliary tripods 13 are opposite to each other and pivotally mounted on each other and are pivotally mounted on the main tripod 12. The main tripod 12 and the two auxiliary tripods 13 can be unfolded so that the bottoms of the main tripod 12 and the two auxiliary tripods 13 are located on the same horizontal plane, or the main tripod 12 and the two auxiliary tripods 13 can be folded into a cone shape.
[0031] like Figure 3 、 Figure 4 、 Figure 6 and Figure 11 As shown, when a user uses the projector lamp of the present invention, the light emitting element 70 can emit light toward the projection side 21 and enter the lens assembly 50. At this time, the light will pass through the optical refractive structures 51 distributed on the inner wall of the lens assembly 50 and be refracted, and then projected into the external environment through the cover 30. Among them, because the optical refractive structures 51 are respectively arranged adjacent to each other along the inner walls of the two lens housings 54 and are in the form of long strips with tapered sides and are evenly arranged, the light can be projected into the multiple strip-shaped light beams 80, and the light is arranged and distributed over a large area.
[0032] Then, if Figures 4 to 7 As shown, the driving assembly 40 can drive the rotating part 41 to rotate. Since the rotating part 41 is inserted into the connecting part 53 of the lens assembly 50 and the shapes of the two correspond, the connecting part 53 of the lens assembly 50 can be driven to rotate, and the matching part 52 of the lens assembly 50 can be synchronously rotated around the fixing seat 60, and the limiting part 61 of the fixing seat 60 can abut the matching part 52 of the lens assembly 50, thereby positioning the lens assembly 50 in the assembly space 22, further improving the rotation stability of the lens assembly 50.
[0033] As above, Figure 4 and Figure 5 As shown, when the lens assembly 50 continues to rotate, it will rotate around the light-emitting element 70, causing the relative angle between each of the optical refractive structures 51 and the light-emitting element 70 to continuously change. Since the optical refractive structures 51 are arc-shaped, the refraction angle of light passing through the optical refractive structures 51 will also change accordingly. As a result, the multiple strip-shaped light beams 80 projected by the projector can produce a light and shadow effect that continuously moves in one direction and loops infinitely, thereby bringing a lively and dynamic visual experience.
[0034] In addition, the LED units 72 of the light-emitting element 70 can be set to different quantities according to user needs, and color lights such as RGB three-color lights, single-color lights or self-changing color lights can be selected to create rich lighting effects through the combination and change of color lights to meet the style and atmosphere requirements of various venues.
[0035] In addition, if Figures 8 to 10 As shown, the base 10 can be folded or unfolded according to environmental requirements. When the base 10 is in the folded state, the main tripod 12 and the two auxiliary tripods 13 can be conical and inserted into natural terrain such as grass or sand, so as to quickly fix the spotlight in outdoor places. When the base 10 is in the unfolded state, the bottoms of the main tripod 12 and the two auxiliary tripods 13 can be located at the same horizontal plane and form a three-point support, thereby stably placing the spotlight on any plane. In addition, the main body 20 can also be removed from the base 10 and the spotlight can be installed above the space in a suspended manner, thereby allowing the spotlight to have a variety of installation methods for users to choose.
[0036] In summary, the projector of the present invention can emit light through the light-emitting element 70 and inject it into the lens assembly 50. The light can be refracted by the optical refractive structures 51 distributed on the inner wall of the lens assembly 50. In addition, the lens assembly 50 can be driven to rotate around the light-emitting element 70, so that the relative angle between each optical refractive structure 51 and the light-emitting element 70 continuously changes, and the refraction angle of the light also changes accordingly. As a result, the plurality of strip-shaped light beams 80 can be projected, and the light and shadow effect of infinite circulation can be formed, forming a dynamic visual experience, which helps to create a joyful and lively atmosphere and effectively liven up the atmosphere of the venue.
