[0022] 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, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figures 1 to 4The diagram shows a schematic representation of a decorative umbrella for ambient lighting according to an embodiment of the present invention. It includes an umbrella surface 1, a handle 2, and a support 3. The umbrella surface 1 has a downward-facing front and an upward-facing back, both sides of which are provided with customized three-dimensional pattern structures. The pattern can be, for example, a ring structure simulating water ripples (as shown in the diagram), or other customized styles as required. The handle 2 is a hollow columnar structure used to accommodate power cords and control circuits, and connects the umbrella surface 1 and the support 3. The support 3 is a hollow shell, with a bottom... The umbrella 1 is connected to a plate-like structure with a hollowed-out pattern. The umbrella support 3 is a shell with a receiving cavity, and the bottom of the umbrella support 3 is connected to a plate-like structure with a hollowed-out pattern. A human body sensing device and two sets of independent LED light source components are installed in the receiving cavity of the umbrella support: the first set of LED light source components projects upwards onto the front of the umbrella surface, and uses an RGBW color-changing module to achieve dynamic color changes; the second set of LED light source components illuminates downwards the hollowed-out pattern, forming a projection effect on the ground corresponding to the hollowed-out shape; the sensing device triggers the linkage of the two sets of light sources to emit light when it detects a human body approaching. For better hanging and fixing, a hook 4 can also be provided on the front of the umbrella surface 1.

[0024] In a specific application example, the three-dimensional pattern structure of the umbrella surface 1 is achieved through a mold forming process to create a textured structure. For instance, the umbrella surface 1 is made of fiberglass material, and a textured water ripple structure is formed by mold stamping. The two surfaces are coated with a high-reflectivity white primer and a custom-colored top layer, respectively.

[0025] In a specific application example, a waterproof sealing ring is installed at the top of the umbrella handle 2 where it is fixedly connected to the umbrella canopy, and the bottom of the umbrella handle 2 is connected to the umbrella support by threads or snaps. The umbrella handle is made of stainless steel tubing, with a pre-reserved channel in the inner diameter for the power cord and control cord to pass through.

[0026] In one specific application example, the bottom of the umbrella holder 3 is provided with an annular magnetic base; the edge of the hollowed-out patterned plate structure is provided with a permanent magnet adsorption area, and the annular magnetic base is attracted and connected to the permanent magnet adsorption area. Alternatively, the bottom of the umbrella holder 3 is provided with a positioning groove; the edge of the hollowed-out patterned plate structure is provided with a protrusion corresponding to the position of the positioning groove, and the positioning groove and the protrusion are engaged.

[0027] In a specific application example, the LED light source component uses an adjustable-focus LED lamp head, which projects the hollowed-out pattern precisely onto the ground through a lens assembly to form a clear light spot. More specifically, the umbrella holder body is an acrylic disc with a rotatable hollowed-out pattern module embedded in the bottom. An opening in the pattern area leads to the central light source chamber. Inside the central light source chamber are two independent LED light source components: the upper layer is a ring array of six RGBW full-color LED beads (15W power); the lower layer consists of four COB white light panels with Fresnel lenses, focusing the light onto the hollowed-out area.

[0028] In a specific application example, the bottom of the umbrella holder 3 is equipped with a wiring port, which is used to achieve array-based synchronous control of multiple lighting atmosphere decorative umbrellas through the central control system.

[0029] In a specific application example, the human body sensing device uses an infrared pyroelectric sensor, or millimeter-wave radar. When human movement is detected within a 3-meter range, the upper RGBW light source initiates a random color cycle, generating a dynamic refraction effect through the umbrella surface texture; the lower white light source is simultaneously activated, projecting the hollowed-out pattern onto the ground to form a light spot corresponding to the hollowed-out pattern.

[0030] The aforementioned atmospheric lighting umbrellas, integrating intelligent sensing, dynamic lighting, and variable projection functions, provide an environmental decoration installation that combines artistic expression and interactivity. Their double-sided, three-dimensional umbrella design enhances the daytime display effect, while the human-sensing-based light and shadow linkage mechanism creates an immersive experience at night, making them suitable for commercial spaces, cultural exhibitions, and other venues requiring atmosphere creation.

[0031] It should be understood that the exemplary embodiments described herein are illustrative and not restrictive. Although one or more embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art will understand that various changes in form and detail may be made without departing from the spirit and scope of the present invention as defined by the appended claims.
