Solar Pooja Lamp That Runs Nonstop

The Solar Pooja Lamp That Runs Nonstop operates by combining solar energy harvesting, energy storage, and discrete solid-state lighting control. During daylight hours, a 10W-peak photovoltaic panel—characterized by a maximum power voltage of 17.5V and a maximum power current of 0.58A—converts ambient light into electrical energy. This electrical power is directed through a diode (D1) to prevent reverse current leakage back into the panel, while a safety fuse (F) protects the downstream circuitry from overcurrent faults. The generated electrical energy serves a dual purpose: it directly illuminates a set of high-brightness yellow LEDs (designated LED1 through LED16) mounted on custom octagonal PCBs inside the brass lamp body, and it simultaneously stores excess energy in supercapacitors (C1 and C2). A network of discrete resistors (R1 through R10) is integrated into the circuit to properly manage current flow and bias the semiconductor components. When ambient light drops at night, the photovoltaic panel ceases to generate power. At this point, the energy previously accumulated in the supercapacitors discharges into the LED circuit to maintain continuous illumination. Because supercapacitors can store and release energy rapidly, they act as robust local power reservoirs, ensuring that the high-brightness yellow LEDs continue to glow without relying on an external grid connection or conventional batteries.
