Technical Field

[0001] The utility model relates to the technical field of circuits, and in particular to a universal remote control circuit capable of utilizing light energy to supplement electricity. Background Art

[0002] Infrared signals are a type of radio signal, also known as infrared light, emitted by electromagnetic energy. Their wavelength is shorter than visible light, making most infrared light invisible. Infrared signals are primarily used in wireless remote controls, entertainment, security systems, and wireless data transmission. Household appliances such as air conditioners and televisions generally support infrared remote control. Security systems use infrared signals to detect changes in external space or paths, also known as infrared vision technology, which can be used to monitor indoor and outdoor activities. Infrared signals are widely used in today's lives. As an alternative to Bluetooth or Wi-Fi, infrared signals offer advantages such as greater efficiency, security, and bandwidth.

[0003] A universal remote control is a wireless transmitter and receiver capable of decoding infrared signals from various remote controls, storing the received signals, and retransmitting them. It primarily consists of a microprocessor integrated chip that generates remote control signals, a crystal oscillator, an amplifier transistor, an infrared light-emitting diode, an infrared receiving diode, a keyboard matrix, and memory. Universal remote controls offer significant convenience in our lives today. However, existing universal remote controls typically use rechargeable lithium-ion batteries as their power source. Frequent use of universal remote controls drains the battery quickly, necessitating frequent charging. During this period, the remote control becomes unusable, which can lead to a less-than-optimal user experience. Utility Model Content
