Hi everyone, I am currently working on an LED grow light which consists of 20 1W blue LEDs, 20 1W red LEDs, and a 10W soft white LED (shown in yellow on my diagram).
I have mocked up what I think the circuit will roughly look like, but need a bit of help with the details of it...
**broken link removed**
The LED specs are as follows:
10W WHITE LED:
* Reverse Voltage:5.0 V
* DC Forward Voltage: Typical: 10 V Max: 12V
* DC Forward Current: Typical: 900mA Max: 1050mA
1W BLUE & RED LED:
* Reverse Voltage:5.0 V
* DC Forward Voltage: Typical: 2.2 V Max: 2.4V
* DC Forward Current:300mA
If anyone can help me work out the following, there will be a donation from the project's budget
- Whether it will work; and if not, what I need to do to it
- The resistance of the resistors
- The max resistance of the variable resistor
- Any additional changes which would benefit it
Please note: I put them into the 5 parallel lines of 4 LEDs just because I thought this might be appropriate, not for any inparticular reason
Look forward to hearing what people have to say, thanks for reading,
Col
