This article shows a simple infra remote control activated light, made with the use of an infra-red receiver IC (integrated circuit). The maximum range can be as long as 20 metres.

You can see my circuit working in this video:

I designed this circuit after reading those articles:

I made my circuit with a traditional 6 V incandescent light bulb. However, you can use an LED light bulb or simply an LED matrix array. Keep in mind that LEDs conduct current in one direction. You can also use a 4.8 V Krypton torch globe:

Step 1: Design the Circuit

I used the old PSpice software to quickly draw my circuit:

Nowadays there are IR receivers that can work with a power supply voltage between 2.5 V and 9 V, or even 20 V. Thus the diode and transistor power supply are optional. Also, modern IR receivers have higher bandwidth and can thus receive higher frequency signals.

Step 2: Simulations

The TTL power supply:

The light bulb is receiving 300 mA current that it needs:

Step 3: Make the Circuit

You can see the big MOSFET transistor with attached heat sink:

I did not have high-power 2.2-ohm high power resistors. Thus I used an alternative. You can replace the 2.2-ohm resistors with a short circuit. However, this will reduce the life time of the MOSFET.
