Hi, I'm andrea.
I study electronic engineering and I'm trying to design horticulture led lamp. I'm sorry but I don't speak English very well.
I have designed some constant current circuits but now I want to design something different with modular approch.
can I post links to products?
I have chosen the LEDs (2 LEDs): 37 Volt, 720 mA --> 24.5 W
I have chosen the LED heat sink.
My project consists of a 60-100 watt power source, 4 leds in parallel. I need to convert 220v AC power line to 37 V DC. I didn't choose the 220V ac-dc main power supply so I don't know its output voltage (it could be 40 Volts). I want to design the most efficient constant current circuit for drive every single led.
I've chosen to power the LEDs in parallel and not in series because I want to use a modular approach (if I want to use 10 LEDs I just have to change the power supply).
I want to design an efficient circuit with minimal heat problem. could you help me find the most suitable components to drive the leds? I know how to design constant current circuit but I don't know which one is the best.
can I post links to products and sites?
Thank you
Andrea
