I am thinking of developing a controller that can adjust the brightness of 12V, 50A, and 600W LED.

I am a beginner in electronics and for a lighting project I bought a dimmable trafo and a touch dimmer with the hope to be able to combine these.
The trafo is a MeanWell LDB-600L, that is a 600mA constant current trafo with a "DIM" input that takes either a PWM signal (100-1kHz)...
Hi! I would be very grateful if you can help me.
I have been building some circuits to turn on a LED when the battery is low (images), but there is a problem: The led dim and blink between the OFF and fully ON state for some minutes.
My circuit consumes 0.23A and is supplied by a 3.7v/1400mAh...
Hi folks, plea for help.
I've wired my daughter's LED fairy lights to a USB-2 supply, but now they're much brighter than the 3 AA batteries made them (and we quite preferred when the batteries were half flat), so I've been trying to find a variable resistor to put in series to reduce the...
I'm working on a micro controller project to do race timing for rowing regattas. It's coming along pretty nicely and I want to add one component: A finish light that will be turned on and off by the microcontroller.
The light needs to be seen from a distance in sunny conditions. I want...
Hi all, a driver circuit needed for lighting a 30W LED* (one color) -
I had a look at the XL6005 datasheet and wanted to make sure I understand it properly based on the following diagram**:
1. To drive the LED with 300mA I should make RS = 0.73 ohm (ILed=0.22/0.73=0.3A)
2. To limit the max...
I made a few Lichtenberg figures and I want to mount them in shadow boxes. I built some LEDs into the box (Three UV along the top and one red on the left under the blue tape) and I am planning on pouring about an inch of epoxy to cover the LEDs and disperse their light. For a power supply, I am...
