Comprising a main body structure, a control module, a first light source assembly, a light modulation assembly and a light-transmitting area, the first light source assembly and the light modulation assembly are arranged in the main body structure, and the light-transmitting area diffuses light to form a dynamic light shadow; a second light source assembly is arranged at the bottom, basic illumination is provided through a diffusion structure, and light path isolation is achieved. The light modulation assembly can be replaced or adjusted in an electric control mode, and gradient and breathing multi-mode projection is generated in cooperation with light source parameters. The control module is integrated on the lamp or externally arranged, and adjusts the light source parameter cooperation relation (brightness proportion and color temperature matching) according to ambient light or instructions. According to the invention, through modularized light path and intelligent control, basic illumination (high brightness and uniformity) and atmosphere projection (dynamic property and low interference) function decoupling is realized, remote control and scene configuration are supported, and aesthetics and energy efficiency are improved.

Description

Technical Field

[0001] The invention relates to the technical field of lighting equipment, and in particular to an optical projection lamp integrating dynamic light and shadow projection and basic lighting. Background Art

[0002] Technical limitations of traditional lamps Existing lighting devices (such as ceiling lamps and chandeliers) mostly use a single light-emitting structure, relying on direct illumination of LED modules or light distribution through diffusion covers, which has the following defects: 1. Single function: only supports fixed light parameter output, and cannot realize dynamic adjustment of light and shadow forms (such as gradient and flow); 2. Insufficient decoration: The projected light spot is monotonous and lacks artistic visual level; 3. Light interference problem: When the main light source and the ambient light source share the same light path, it is easy to cause glare or blurred projection.

[0003] Disadvantages of existing improved technologies In order to improve the decorativeness of lamps, some solutions try to introduce auxiliary light effect components, such as: ●Backlight module: The light strip forms the outline light, but it is limited to static monochrome light effect; ●Projection structure: The pattern is projected using pattern pieces, which has the problems of difficult switching and easy interference from the main light source. The following core issues are not resolved: 1. Conflict between the light paths of basic lighting and ambient projection: When the high-brightness main light source and the low-brightness ambient light source share the same diffusion cover, the light effects interfere with each other, resulting in blurred projection or reduced lighting uniformity; 2. Discreteness of the control system: The main light source and the ambient light source are controlled independently, lacking a coordinated adjustment mechanism, and unable to achieve scene-based linkage (such as automatically switching modes according to ambient light); 3. Limited scalability: Optical components (such as pattern pieces) are solidified into the lamp structure, and users cannot replace or upgrade the projection effect as needed.

[0004] Technology development trends and user demand upgrades According to market research (2023 Global Smart Lighting Consumption Report), 76% of users expect lamps to have "scene adaptive capabilities", that is, to automatically adjust the lighting mode according to time and activity type; 62% of users pay attention to "lighting artistry", requiring the light and shadow projected on the ceiling / wall to have dynamic changes and personalized customization capabilities. At the same time, the popularity of smart home protocols (such as Matter and Zigbee 3.0) has promoted the demand for cross-device linkage. Lamps need to support remote control, voice interaction and data-driven decision-making as smart nodes. Gaps in existing technology: There is an urgent need for a lighting design solution that integrates physical optical path isolation, dynamic optical modulation and intelligent collaborative control to achieve functional decoupling of basic lighting and atmosphere projection within a limited structural space, while supporting user-defined light and shadow effects and scene rules. Summary of the invention

[0005] Purpose of the Invention Provide an optical projection lamp to achieve functional decoupling of basic lighting and dynamic atmosphere projection, and support customization of light and shadow effects and scene-based linkage control.

[0006] Technical Solution Overview An optical projection lamp, comprising: Main structure: Contains light-transmitting area and has optical diffusion characteristics; The first light source component is arranged inside the main structure to generate a basic light field; Light modulation component: located in the light path of the light source, it modulates the light initially to generate a structured light field; Transparent area: secondary processing of the structured light field to form preset light and shadow on the bearing surface; Control module: dynamically adjust light and shadow visual parameters and multi-light source coordination logic.

[0007] Core Implementation 1. Light modulation components (1) Type: physical texture film (water pattern film, film), electronically controlled element (liquid crystal film, diffraction grating); (2) Function: Convert direct light from the light source into a textured light spot, which is diffused through the light-transmitting area to form a uniform light and shadow. 2. Control module (1) Control method: local switch, voice command, APP remote control; (2) Function: Independently adjust the brightness / color temperature / color of the first light source, and preset dynamic modes (wave gradient, breathing rhythm). 3. Flexibility of installation structure Removable connecting components: adsorption parts, magnetic parts, lifting parts, independent support parts (tripod, counterweight base). 4. Second light source assembly (1) Function: Provide diffuse ambient lighting, physically isolated from the optical path of the first light source; (2) Control logic: Dynamically adjust the brightness ratio of the dual light sources based on ambient light or user instructions.

[0008] Example Extension 1. Dynamic light modulation: the electrically controlled liquid crystal film switches the projection pattern in real time; 2. Distributed control: External intelligent gateway controls via Wi-Fi / Bluetooth networking; 3. Suspended installation: The main structure is suspended and connected to the magnetic base through the magnetic suction module.

[0009] Technical advantages 1. Physical optical path isolation: dual light sources have independent optical paths to avoid mutual interference; 2. Dynamic adjustability: supports stepless adjustment of light and shadow parameters and scene mode presets; 3. Modular expansion: replaceable light modulation components to meet diverse projection needs. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0016] Core structure embodiment (combined with Figure 1 - Figure 3 ) ●Main structure 4: The side wall 41 is provided with a light-transmitting area 43 (frosted / prismatic microstructure), the top wall 42 is fixed to the ceiling by screws or a buckle structure, and the panel 2 is detachably connected to the side wall 41 (such as buckles or magnets), or is integrally formed with the side wall 41; ●Light modulation component 8: The surface of the water wave sheet is provided with a wave texture, which converts the direct light of the first light source component 7 into a dynamic light spot; ●Control module 5: built into the main structure 4 or an external gateway, supporting Bluetooth / Wi-Fi communication.

[0017] Installation method extension 1. Independent placement mode: The bottom of the main structure can be detachably connected to an independent support (such as a metal base, tripod or counterweight bracket), so that the lamp can be placed independently on a load-bearing surface such as a desktop, the ground, or the base of the lamp. 2. Fixed installation mode: (1) Ceiling installation: The top wall 42 of the main structure is provided with a fixing slot, which is directly fixed to the pre-drilled holes in the ceiling by expansion bolts; it is suitable for scenes with low floor heights, and the entire lamp is close to the ceiling, saving space. (2) Suspension wire installation: An adjustable length suspension wire (such as a nylon rope + power cord integrated design) is connected to the top of the main structure 4, and the end of the suspension wire is fixed to the ceiling through a hook; the length of the suspension wire supports custom adjustment (such as 0.5-2 meters), which is suitable for high-rise spaces such as lofts. (3) Magnetic installation: A magnetic module (such as a neodymium iron boron magnet) is embedded in the top wall 42 of the main structure, and is adsorbed and connected to the magnetic guide rail or iron substrate pre-installed on the ceiling; it supports rapid disassembly and position adjustment, making it easy to clean or replace the light modulation component.

[0018] Second light source assembly embodiment 1. Direct-light type second light source assembly (combined with Figure 1 - Figure 3 ): (1) The second light source assembly 10 (such as COB LED) is directly mounted on the bottom wall of the panel 2, and the light is evenly scattered by the auxiliary cover 1 (diffuser plate) to provide basic ambient lighting; (2) The surface of the auxiliary cover body 1 is provided with an optical microstructure (such as beaded dots) to avoid glare and improve light effect. (3) The auxiliary cover body 1 is made of light-transmitting or semi-light-transmitting material. 2. Side-emitting second light source assembly (Solution 2) (combined with Figure 4 - Figure 5 ): (1) The second light source assembly 10 is disposed in a groove on the side of the panel 2, and light is transmitted to the auxiliary cover 1 through a light guide plate (such as PMMA), thereby realizing a frameless design with side light output; (2) Suitable for ultra-thin lamps to improve aesthetics. (3) The auxiliary cover body 1 is made of light-transmitting or semi-light-transmitting material.

[0019] Motion Control and Scene Modes 1. Single mode control: (1) Basic lighting mode: only the second light source assembly 10 is turned on, the brightness is adjustable (e.g., 100-3000 lumens), and the color temperature range is 2700K-6500K; (2) Atmosphere projection mode: Only the first light source assembly 7 is turned on to project dynamic water ripple light and shadow, with a brightness lower than 50 lumens to adapt to night scenes. 2. Hybrid mode and intelligent linkage: (1) Mixed mode: The first light source assembly 7 and the second light source assembly 10 are turned on at the same time, and the control module 5 automatically adjusts the brightness ratio of the two according to the ambient light sensor data (for example, when the ambient light is lower than 50 lux, the brightness of the auxiliary light source is reduced to 30%); (2) Example of scenario rules: ① Sleeping aid mode: After 22:00, the second light source assembly 10 is automatically turned off, and the breathing gradient effect of the first light source assembly 7 is activated (cycle 10 seconds); ② Party mode: the first light source assembly 7 is switched to color dynamic projection (RGB light source + rotating texture sheet), and the second light source assembly 10 is adjusted to warm white light.

[0020] Light Modulation Assembly Alternative Embodiments 1. Film replacement solution: Replace the light modulation component (water ripple film) 8 with a high-transmittance film, and print customized patterns (such as starry sky, leaf shadows) on its surface to achieve a static projection effect. 2. Dynamic liquid crystal film solution: The light modulation component (water ripple film) 8 adopts an electrically controlled liquid crystal film, which adjusts the light-transmitting area of ​​the film layer by changing the voltage to achieve dynamic switching of the projection pattern (such as flowing water → flame).

[0021] Technical effect verification Through the above-mentioned embodiments, the present invention can achieve the following advantages: 1. Light path isolation: The light-transmitting area 43 is physically separated from the auxiliary cover 1 to prevent high-brightness basic lighting from interfering with the clarity of the atmosphere projection; 2. Functional compatibility: Expand the application scenarios of lamps through modular design (such as replaceable light modulation components 8 and magnetic installation); 3. Energy efficiency optimization: The control module 5 automatically switches to a low power consumption mode (eg, night mode power < 2W) according to the usage scenario.
