Flexible Solar LED Light Eliminates Wiring Complexity

The patent extracts and eliminates the complex sun-tracking mechanism from the solar lighting system. Instead of using traditional arrays with motors and sensors to track the sun, the invention uses a simple flexible solar cell that passively collects sunlight throughout the day, significantly reducing device complexity while maintaining adequate energy collection for nighttime illumination.

The patent employs a flexible solar cell that can be positioned at various angles and orientations to optimize sunlight capture without mechanical tracking. The flexibility allows the cell to be mounted on surfaces of any shape and angle, adapting dynamically to installation requirements while eliminating complex active tracking mechanisms.

The patent uses a small rechargeable battery instead of a large energy storage system. The battery is recharged daily by the flexible solar cell during daylight hours and discharged at night to power the LED. This approach accepts that the energy storage capacity is limited but sufficient for the intended application, avoiding the need for large, bulky storage devices.

The patent changes the operating parameters of the lighting system by using ultra-low-power LED technology that requires minimal energy storage. The LED operates at very low current and power levels, allowing the system to function with a small battery and compact solar cell, dramatically reducing the overall system volume compared to traditional lighting approaches.

The patent integrates the power source (solar cell and battery) directly into each individual light unit, eliminating the need for multiple wires connecting multiple lights in series or parallel. Each light is a self-contained module with its own power generation and storage, removing the vulnerability of wire-based connections while maintaining adequate power delivery to the LED.

The patent divides the lighting system into independent modular units, where each light contains its own solar cell, battery, and LED circuitry. This segmentation eliminates the need for extensive wiring between components and lights, as each module is self-powered. The modular design improves reliability by isolating potential failure points to individual units rather than creating system-wide vulnerability through wiring.

The patent replaces the AC power system with a DC system powered by solar energy stored in a battery. This substitution eliminates the need for AC-to-DC conversion circuitry, heavy-gauge wiring, circuit breakers, and other components associated with AC power distribution. The low-voltage DC system inherently reduces electrical hazard risks while providing sufficient illumination through efficient LED technology.

The patent uses a small rechargeable battery instead of connection to the AC power grid. The battery is recharged daily from the solar cell and provides power for nighttime illumination. This approach accepts the limited capacity of small batteries but eliminates the safety hazards and infrastructure requirements of AC power, making the system suitable for outdoor and remote installations.
