Home Made Survival Flashlight: For Camping (updated 1 time)

The above is an invention of mine that can work in any weather condition and cannot break. You charge it up in daylight, when it's in the "off" position. And at night it can be put behind your ear (like putting a pen behind your ear) in order to have hands free light. And you want to have a big enough capacitor to work all night long. And it will charge itself in even minimal light. But the solar panel has to be the perfect voltage, to not burn out the LED. And the LED is super bright to cut down on space needed to produce brightest light. Therefore it's a perfect small pen light.
LATER ADDED: What this circuit diagram also needs is a current regulator of some kind because capacitors loose current just as fast as they loose voltage. but batteries on the other hand loose voltage but have a constant current which is why they are preferred when not in extreme weather conditions. So what needs to be added into the circuit is a voltage regulation circuit or a Zener diode.
