A simple LED lamp circuit from scrap. Uses 5 LED and takes only 50 mA
The project involves redesigning a compact fluorescent lamp (CFL) to function as an energy-efficient LED lamp. The primary objective is to create a circuit that operates at a low current of 50mA while providing sufficient illumination for various applications, such as night lights or table lamps.
To achieve this, the circuit will utilize a suitable LED driver circuit that regulates the current flowing through the LED. The circuit should include a rectifier to convert AC to DC, as well as a voltage regulator to maintain a stable output voltage suitable for the LEDs. A common approach is to use a buck converter or a constant current source to ensure that the LED operates within its specified current range.
The design will also incorporate a heat sink to dissipate any excess heat generated by the LED during operation, ensuring longevity and reliability. The use of a microcontroller or a simple timer circuit can facilitate features such as dimming or automatic shut-off to enhance energy savings.
The LED array should be selected based on the desired brightness and color temperature, ensuring that the total forward voltage matches the output of the driver circuit. Proper thermal management and electrical isolation will be critical to ensure safety and efficiency.
Additionally, the enclosure for the modified lamp should be designed to allow for adequate ventilation and heat dissipation while maintaining an appealing aesthetic suitable for home decor. Overall, this project aims to provide a sustainable lighting solution by repurposing existing CFLs, thus reducing waste and promoting energy efficiency.Convert a used CFL into a power saving LED lamp circuit that consumes only 50mA. This gadget can be used in applications like night light, table lamp etc.. 🔗 External reference
