[0002] In the lighting field, with the increasing demand for energy conservation, environmental protection, and intelligent technology, solar-powered LED intelligent sensor lights have emerged. Traditional lighting fixtures rely on mains power, which not only consumes a lot of electricity and increases electricity costs, but also makes installation and use extremely inconvenient in some outdoor locations where wiring is difficult, such as remote courtyards, rural roads, parks, and scenic spots.

[0003] While existing solar-powered sensor lights have addressed energy and intelligent control issues to some extent, their functionality is relatively limited, mostly offering only basic lighting and motion-activated on / off functionality. For scenarios with personalized decorative needs, such as commercial shops seeking to attract customers with unique lighting effects, or boutique guesthouses aiming to create a distinctive nighttime atmosphere, ordinary solar-powered sensor lights are insufficient.

[0004] Furthermore, existing sensor lights on the market often lack angle adjustment capabilities, making it difficult to flexibly adjust the direction of illumination according to actual lighting needs, thus limiting their application effectiveness in different scenarios. The pattern projection solar LED intelligent sensor light proposed in this patent is specifically designed to address these shortcomings of existing technologies. Utility Model Content

[0061] I. Energy Conversion and Storage Processes

[0062] Solar energy collection phase

[0063] Under sunlight, the monocrystalline silicon solar panel 5 at the top of the mounting base 4 converts light energy into electrical energy (open circuit voltage 18V, short circuit current 2.5A) through the photovoltaic effect. The generated DC power is transmitted to the charging management module of the intelligent control mechanism via a 2.5mm² photovoltaic cable (MC4 waterproof plug connection).

[0064] Core principle: Utilizing the photovoltaic effect of a semiconductor PN junction, photon energy excites electron-hole pairs to form a directional current.

[0065] Energy storage stage

[0066] The charging management module (MPPT control chip) converts the unstable voltage output from the solar panel into a stable 12.8V DC power to charge the lithium battery pack (4 3.2V lithium iron phosphate batteries in series, with a total capacity of 5000mAh). At the same time, it implements overcharge protection (threshold 14.4V) through the protection module.

[0067] Key function: MPPT technology can track the maximum power point, keeping charging efficiency above 95%.

[0068] Power switching mechanism

[0069] When the ambient light sensor detects that the light intensity is below 20 lux (such as at night), the main control module (STM32F103 microcontroller) automatically switches to discharge mode, and the lithium battery pack powers the LED projector through the LED driver module.

[0070] II. Intelligent Sensing and Lighting Control Process

[0071] Environmental perception stage

[0072] An ambient light sensor (photoresistor) monitors the light intensity in real time and transmits the data to the main control module to ensure that the lights only start when there is insufficient light (avoiding ineffective operation during the day).

[0073] The infrared sensing module (sensing distance 5~8m, angle 120°) detects human infrared radiation and generates an electrical signal to trigger the main control module.

[0074] Lighting start-up and adjustment phase

[0075] When the sensing module detects human activity and the ambient light is insufficient, the main control module sends a command to the LED driver module to drive three 10W COB LEDs to light up (operating voltage 12V, luminous flux 2700lm).

[0076] Brightness adjustment: The LED driver module achieves stepless brightness adjustment by changing the current (0~1500mA). The default initial brightness is 100%, and it drops to 30% energy-saving mode after a delay of 10~600s.

[0077] Closure mechanism

[0078] When no one is active in the sensing area and the set delay time is reached, the main control module cuts off the power supply to the LED driver module, and the lamp enters sleep mode (standby power consumption ≤ 0.1W).

[0079] III. Pattern Projection Principle

[0080] The light emitted by the LED projector inside the LED lampshade 2 passes through the pattern template (50mm×50mm) magnetically fixed in front of the LED beads. The light is modulated by the hollow pattern on the template and then projected onto the ground or wall through the high-transmittance PC lampshade (transmittance ≥90%), forming a clear light and shadow pattern.

[0081] Optical characteristics: The 30° beam angle design makes the edges of the pattern sharp, and the frosted inner wall of the lampshade can soften the edge halo and enhance the visual appeal of the pattern.

[0082] IV. Working Principle of Angle Adjustment Mechanism

[0083] coarse adjustment stage

[0084] Loosen the bolt body 16 (8.8 grade high strength bolt), and realign it with the screw groove of the induction lamp holder 1 through the 6 M6 mounting screw holes 15 (30° interval) on the bearing plate 8 to achieve graded angle adjustment within the range of ±90°. After tightening the bolt, anti-slip fixation is achieved by the elastic compression of the spring 167 (stiffness 5N / mm) and the annular rubber sheet 162 (Shore hardness 70).

[0085] Fine-tuning stage

[0086] Loosen the M5 screw 14 on the ball sleeve 11. The ball 10 (diameter 20mm) can rotate ±30° in the ball sleeve 11 (inner diameter 20.2mm). After adjusting to the target angle, tighten the screw. The end rubber pad (Shore hardness 60) is in close contact with the surface of the ball, and the angle is locked by friction (tightening torque 2~3N・m).

[0087] V. Coordinated Operation of Protection Mechanisms

[0088] Overcharge protection: When the lithium battery voltage reaches 14.4V, the charging management module cuts off the charging circuit;

[0089] Over-discharge protection: When the voltage drops below 10V, the main control module stops supplying power to prevent battery damage;

[0090] Short circuit protection: When the circuit current exceeds 5A, the protection module will cut off the circuit within 10ms;

[0091] Waterproof and dustproof: IP65 protection rating is achieved through silicone sealing rings and waterproof plugs, ensuring stable operation in outdoor environments.
