I fixed a China Torch with New LEDs and a Diode, it failed probably on a drop shock, the battery wire cut … then when put on charge Few LEDs went bad, as battery was absent in ckt.
design review – 1.5uF voltage rating can increase like 440V AC. A current source with low dropout voltage would be great but it builds the cost. The wiring has to be robust. A diode added to keep LED current within some limits on batt overcharge.
These type of Torches and Lanterns should not be Turned on when charging. This may blow the LED Array.
LED Night lamp, Clock Lamp to see time at night. It is a Green Lamp just 50mA, but its Blue in Color.
This can be a first LED Lighting project anybody can do. Just twist wire, use insulation tape. Get a Nice Mains adapter that will provide 6V DC. 5V also will do. A prior Knowledge of Ohm’s law is essential.
LED’s are used as Indicators, Annunciations and now for Lighting. When i used to make gadgets, there was only Red, Yellow and Green and nothing In-between.
Now we have Blue ! and White as in Flashlight and probably much more like Oled and LED Monitors and TV. Here are some Old and New Schoodles of mine. Schoodle is a Schematic Doodle.
