We will make series of peltiers wires --ive of one peltier and +ive wire of other peltier as so on at the end first and last two wires will remain left. These two red +ive wire and black --ive wire will be connected to volt boosting circuit's input side of the circuit. And LED wires +ive and --ive will be connected to the circuit +ve and --ve terminals respectively output side of the circuit. At the end we fix the LED lamp with heat sink using Silicone Sealant.
Sketch the Head lamp Before we make a actual head lamp first we will make sketch then make a real as it.
Updated heat sink
This is almost the same headlamp like previous but having updated heat sinks light weight and having lags. Actually a heat sink having more legs give better results. In previous head lamp we used aluminum blocks of heat sink. Hard wire length 43 cm heat sink squire size
40.5mm we need. Strips size are respectively 22,1 cm and 32,2 cm
Other steps are as same as the previous headlamp these pictures will help you how to connect peltiers with heat sink using thermal past.
LED Lamp +ve and –ve wires we will connect with volt boosting circuit’s output side. +ve wire with +ve side of circuit and –ve wire with –ve side of circuit.
These remaining red wire +ve and black wire –ve will be connected on volt boosting circuit’s on input side red wire with +ve and black wire –ve side of circuit.
After this we will cut extra wires from peltiers . Now will make series of connections red wire will be connected with black wire. Just we will leave first and last wire for connecting them with volt boosting circuit
For making body heat powered lamp first we need 4 aluminum blocks for heat sink propos. In 4 aluminum blocks we make at least 2 wholes. Then We will connect 4 blocks with hard wire passing by all 4 blocks wholes. First and last side of hard wire will fix two strips with this our headlamp will easily be hold on our forehead.
If We see of any where almost all electronics things having battery are need to be charge.
There are a lot of moment came in our life when we are away from power source and there are a lot of people who do not have electricity and solar is not available for 24 hour. At night also batteries required for charging during day time. But it is not on demand when you need at night. Many of our children can not get their education because they do not have light at night. I hope with this technology they have big hope for education also they will take part in science and technology and make our feature more bright.
For better results it more important to use thermal paste in between aluminium rectangle pipe and peltier. With this aluminium will keep the peltier at room temperature.
Heat sink
Your aluminium rectangle pipe should be like a heat sink. This will also keep the peltier at room temperature all the time.
LED Selection
If you have Strawhat 8mm 0.25W LED its ok. Actually I find 1W special LED has better results not every 1W LED. If you find this 1W LED then take other strawhat LED is ok. Every 1W LED has a yellow colour dot in its centre. Always take that 1W LED that has very small yellow colour dot. You can see in the picture yellow dot. The LEDs having mark are ok and having cross are not ok.
