4 LED FLASHLIGHT

Introduction: 4 LED FLASHLIGHT

About: I love to learn,build and design.....

AIM:To construct LED torch (4 led's in parallel)

APPARATUS REQUIRED: Soldering iron,multimeter , gum tapes.

COMPONENTS REQUIRED: Led's(4),battery container(6V),Wires,pressing switch,batteries(rechargeable recommended),resistors(if required),reflector.



First connect leds in parallel then connect it to switch then to battery if led are connected in series voltage at each led will be different
so to cope up with this leds are connected in parallel. As we have connected leds to rechargeable batteries each battery is of 1.2V so 4 batteries in series make 4.8V which is enough to light the led.

Step 5:

If the leds are becoming  very hot you can use a resistor to resist some amount of current and intensity of the light is also lost but battery may come for longer life...
