I am trying to experiment and gain an understanding of lighting. Attached is a document with my schematic, most likely off. I think my diode is not places right in the circuit. If someone drew an update it would be grealty appreciated.
I have 10 1W LEDs with a foraward voltage of 3.3 to 3.6V and forward current of 350mA. they are also 80lm a piece. I want to create an energy effieicnt bulb using all 10 LEDs, giving me 350mA, 33 to 36 forawrd voltage, and 800 lumens output.
Problems I faced are regulating the voltage in and controlling it. I figured a zener diode voltage regulator would work. Its for a light bulb so I couldn't place in a transformer and save cost. I added a fuse to protect teh LEDs from current, then a capacitor C1 to store some charge, then a full wave bridge rectifier to go from AC to DC voltage becaus ethe LEDs run on DC. If not theyd keep blinking on and off. Then I put a capacitor C2 to smooth the signal from the rectifier, a resistor Rs to control the bleeding from teh capacitor when the bulb discharges. Then i used a zener with that resistor to control the voltage coming into the LED part of teh bulb.
There might be a reistor needed, liek a load resistor after the zener, and before the LEDs, and also I think the Rs resistor should be in series to act almost like a shunt resistor.
If you have any tips
1. Improving the circuit or fixing it
2. Controlling the 120 +/- 10V coming from the wall and current
3. Making it effieicnt comparable to 100W or 60W incandescent
or any feedback at all,
please let me know. Its a small project, and I am looking to cut the cost back to build it as I spent a lot on materials so far. I was also wondering if the bulb has 10W from the LEDs, does that make it a 10W bulb? Im just looking for help and clarity.
-Thank you so much for any help you can aide me with.
