In this circuit we will drive an led directly from 230v ac mains supply.
Diy led grow light schematic.
White led bulbs cost 1 w retail and sometimes 0 50 w if there is a green subsidy instant rebate.
Since i wanted to do something similar my first grow light model is built from 10 red and 4 blue 3mm leds connected to some resistors.
White leds emit more green light than typical grow lights which unfortunately isn t used very efficiently by plants.
This is a legal prop 215 grow what up.
However paying for the electricity to.
My first intent is to make a portable grow light as i got inspired for a while by one cheap usb led grow light sold by banggood.
And the only way to change the.
E red 1 63v 2 03v and blue 2 48v 3 7v.
I ve been on the fence for a while and decided to take the leap after seeing some success with other peoples grow.
In this we designed an led light bulb and used it as a regular bulb.
My grow light is a 28 led mix red blue white that will cost me about 30 and the same light runs 300 500 in some on the large lighting companies.
Making your own light is a lot of fun and if you put money towards creating your own light rather than buying a premade unit off of amazon or ebay you ll end up with a final product that s far more powerful and efficient.
The big problem with grow lights and i m sure your aware of this is the different forward voltages of the different colors i.
Led current in amps 1 25 r3 so for a current of 550ma set r3 to 2 2 ohms you ll need a power resistor usually r3 power in watts 1 56 r3 this circuit also has the drawback that the only way to use it with a micro controller or pwm is to turn the entire thing on and off with a power fet.
Another interesting led circuit is the diy led light bulb.
Here is a 23v0v led driver circuit.
It is very dangerous to use 230v ac supply on breadboard.
Led strip light internal schematic and voltage information this article goes over the inner circuitry and workings of an led strip light.
Hopefully those looking for practical information on electrical circuits and wiring led components found this guide first.
Been lurking around the led threads and finally decided to do a grow thread with my new led.
It s likely though you ve already read the wikipedia page about series and parallel circuits here maybe a few other google search results on the subject and are still unclear or wanting more specific information as it pertains to leds.
