SunFlow Reading Lamp / Solar powered LED Reading Lamp

SunFlow Reading Lamp

'SunFlow' is a solar powered LED reading lamp. It has three independently rotatable LED lamp heads. These lamp heads can be rotated to any angle, any number of times. So the light can be shared by three people sitting in different directions. The LED lamp heads can be independently switched ON by the touch of a push button.
Charging of 'SunFlow' is done either from a solar panel or from a normal electric power outlet. This is a useful feature on cloudy days.
A microcontroller based circuit monitors the battery charging as well as provides a lot of additional features like showing the battery life in 'minutes remaining' on an LCD.
