I am building a long strip to go around the perimeter of my home theater room. The total length of the strip should be right at 65’. I am planning to use RGBW BTF-Lighting strips model number HD-24V-5050-4IN1-96L-B-IP30. I am also planning to use a Mean Well LRS-350-24 Power Supply and a GLEDOPTO GL-C-601P controller. I am trying to figure out, do I just run a wire from one of the +V terminals of the power supply to the 24V+ trace on the light strip since all of the lights use the same ground? The connectors that came with the lights are 5-pin connectors with Bl, G, R, B, W wires. Is there a way to determine where the power injection should be done? I was thinking that the front of the first segment would get power from the power supply via the connector connecting to it. I was then thinking of injecting into the beginning of each of the subsequent 3 segments and at the end of the last segment. This would be a total of 5 power connections…could I get a fuse block, run power from one of the V+ terminals on the power supply to the block and then a fused power wire out to each injection point? I would also power the controller off the power supply but only connect the RGBW wires out to the strip. I did not include a link to the controller because I am limited to 2 links.
You realize, those are Analog LEDs right? Means you can set the colour/brightness for the whole strip at once, but can’t control individual LED’s separately.
Whatever controller you get, it’ll need some hefty drivers to handle the current for each of the R,G,B,W channels.
Other than that, power distribution is similar to that used for addressable LEDs. In general you space your injection points to try and reasonably distribute the current required. For non-addressable LEDs, you’ll get dimming issues as the voltage “sags” but not the same colour rendering issues common with addressable.
This is my first go at building an LED implementation and the information out there is mind numbing. What do you mean by the “driver” comment? I have a power supply and a controller…is there something else that is needed? I don’t really care about having individually addressable…setting the color/brightness of the strip meets my needs.
With addressable LEDs, power is supplied to every LED from a common “Bus” V+ and GND.
The colour and brightness info comes from the data line that joins every LED in series in the strip.
With analogue LEDs, you have four (R,G,B,W) “classes” of LED all connected in parallel.
They are powered by connecting V+ on the strip to your PS and when you connect R,G,B, or W to Ground, that particular colour of the strip will light up. When you hook up to the conroller, each channel must be able to control the current required for the total # of LEDs you have connected.
That’s different than addressable LEDs where only the power supply needs to be sized for the number of LEDs.
