Introduction: Light of My Life 2
It is a simple lamp to add mood lighting to a room or focused light on a table
The idea is to have a fixed source of light, with a reflector to direct the light on a table or a wall or let it hit the roof. this is in principle opposite to most lamps which throw the light down by default
the lamp is made from simple parts a few 10mm bright LED's, a Pringles can and a CD
Step 1: Bits and Pieces
8-10 high bright 10mm LED's
general purpose PCB, berg strip connectors and some connecting wires
a 7805 voltage regulator and 220ohm trim-potentiometer
a pringles can or a similar cylindrical shape
a clead CD/DVD
a bicycle spoke
a small piece of pvc pipe
Some usefull tools:soldering iron, solder wire, flux
cutter, scissors
pens, markers and scale
cable ties
adhesive tape
a dremel
Step 2: The Heart of the Light
Step1:
solder the LED's on the PCB in an approximately circular fashion
LED's can be connected in parallel or any combination depending to the power source available
i connected them in parallel because i intend to drive them with a constant current source
Step2:
solder the constant current source made as per the circuit diagram shown in the link below

Step 3: The Soul of the Light
cut a 50 mm long piece from the base of the Pringles can
cut another 50 mm long piece; and then cut this piece legthwise
compress the small piece, insert it in the rest of the can and tape it in shape.
fix the PCB with the LED's sandwiched between the base of the can and the other cut piece with two or three cable ties
fix the LED driver on the bottom can or another suitable place
make the electrical connections and test the LED's once
Step 4: Means of Spreading the Light
fix a spoke on the can with the adhesive tape
make a hole in the PVC pipe, roughly at the centre lengthwise, to fit snugly on the spoke, add some masking tape on the spoke to make it rough
make a slit in the CD on one side and 4 holes for fixing the pipe to the CD
fix the PVC pipe to the CD using cable ties, aligning the hole with the slit
slide the pipe and CD on the spoke
Step 5: Filling the Can With Light
the completed lamp
Step 6: Bringing Light Where There Was None
the CD reflects the light in different ways and creates multi-coloured effects
a more polished reflector will give cleaner light
