Circuit diagram for a mini emergency lamp. This mini emergency lamp activates during power failures to provide cool white light in the room. It utilizes a 1-watt white LED to deliver adequate illumination.
The circuit for the mini emergency lamp is designed to be simple yet effective for providing illumination during power outages. The primary components include a 1-watt white LED, a rechargeable battery, a charging circuit, a power switch, and a control circuit that detects power failure.
When the main power supply is operational, the charging circuit ensures that the rechargeable battery is kept at full charge. This can be achieved using a small solar panel or a conventional AC-DC adapter, depending on the intended use and design preferences. The charging circuit typically consists of a diode to prevent backflow of current, a voltage regulator to maintain the battery voltage within safe limits, and a current limiting resistor to protect the LED from excessive current.
Upon detection of a power failure, the control circuit activates, switching the LED on to provide light. This can be accomplished through a relay or a MOSFET that connects the LED to the battery. The LED is chosen for its efficiency and long life, making it suitable for emergency lighting applications. The output of the LED should be connected through a current-limiting resistor to ensure that it operates within its rated specifications.
To enhance usability, the lamp may also include features such as an indicator LED to show when the unit is charging or fully charged, as well as a switch to allow the user to turn the lamp on or off manually. Additional components may include a fuse for overcurrent protection, ensuring the safety and reliability of the device during operation.
Overall, the mini emergency lamp circuit is a practical solution for providing essential lighting in times of need, with a focus on simplicity, efficiency, and reliability.Circuit Diagram for Mini Emergency Lamp.
