To show the versatility of the solar LED chips, I was able to run a 6 volt, 4 AA battery lantern with just 2 AA batteries:
The LED's on top can be rotated to shine up or down on a cone deflector with two levels of brightness and a flashing mode.
Even with the 5252 circuit, it had 2 levels and flashing mode. I just couldn't turn it off. So the chip can create
If the chip circuit can be wired internally then perhaps the on/off switch can cut off the chip ground
to keep it turned off.
I had previously made a AA battery eliminator with a 5252F chip so I could swap it for the first positive battery going directly to the LED's:
The eliminator goes in the top positive end and the last battery is jumpered out with a black wire to the
negative block end on right. The chip requires a ground from a side spring so I jumpered it to ground on
the negative end also which sadly bypasses the switch.
2 AA batteries follow to supply 3 volts to the circuit in the other half of the battery pack. The 5252F will double that voltage!
This can only be a temporary circuit as the chip ground is not switched off by the lantern and it would drain it if left in permanently!9 LED's!
It just proves that the chip can be used to replace half of 2 or 4 battery LED lamps. 3 battery
ones would be dimmer but possible too. Remember that the coil sets the LED current. 20 to 30 ma is best
for all BRIGHT LED's! Red, yellow and green normal LED's may burn out as they need less current!PS: The photograph above does not show how bright the 9 LED's really are!
