LEDS RGB 5050 VS LEDS RGB 3528

Other Hardware General Electronics

that the difference between the RGB LEDs 5050 and 3538 rgb leds? What consumption?
I do not understand, the datasheep says both RGB LEDs consume 20 mA,
3528 or RGB LEDs per channel, consumes 6.6 mA?, and 5050 LEDs consume 60 mA, 20 mA per channel?

5050 and 3528 refer to the physical dimensions of the surface mount parts. [u]Here's a link[/u].

For the current ratings an other information, you'll have to check the datasheet for the particular part.

5050 SMD LEDs typically have three LEDs in each package (usually 20mA ones). RGB 5050 LEDs have a red, green, and blue LED in each package, so each LED can have any color.

3528 is a smaller package, and such LEDs typically have only one LED per package (though it may be brighter than a single element in 5050 package, and consume more current - see specs). I do not think RGB LEDs are available in this package.

If RGB LED strip is made with 3528 LEDs, there would be separate red, green, and blue leds (alternating) on the strip. That's probably not going to look as nice. For single-color led strip, however, the smaller 3528 LEDs are often spaced closer together, resulting in a more even light, which would probably look better.

which is consumption, (ampere A) per channel RGB LEDs 3528 ??

Actually - I just found some RGB 3528 LEDs - 4 pins - so they do exist (though at least some of the "3528 RGB LED" strips on the market use separate red, green and blue LEDs...)

To know how much current they use, consult the manufacturer's specifications or pull the datasheet for the LEDs, and do the math. They're probably 20mA per element.

link to the RGB 3528's under one hood?

then leds Cada rgb 3528 consume 60 mA ??

The model I linked, yes. For other ones, that may not be the case.

ahh.. separate/individual ones. (I was thinking it was a 'strip' already).. still thanks for the share. I dont think I have ever worked with 3528's before)

I suspect strips made with them exist - but I haven't seen any, only the ones with red, green, and blue 3528's.

12

Those are the ones I have seen as well (single R, G or B lines)..

still nice to know they are out there.. (even in strips)..

sometimes the 5050 package doesnt work for me... (nor does the 60mA requirement sometimes either!!, *I understand the 3528 will be same current draw as well) lol..

If 60mA/led is too much, run it at lower voltage :wink: (or, where possible, use bigger resistors)
