Hello All,

I am trying to make a light with 5050 strip LEDs and am currently trying to find a LED driver. The ones which I have found are too bulky for what I want and I came across this one http://www.gve-cn.com/ProductImgFile/20110411134932.pdf which is ideal size wise. Some LED strips that I want to use have an output of about 13W, would this driver work with it? I can see the driver says 20W on the spec sheet but I am not to sure if this means I will be able to use it in conjunction with the LED strip.

Also if I am wanting to dim it mannually can I use a simple potentiometer in series with the driver and LED?

Be grateful if anyone could help me out.

Thanks,

This product needs a 12v 5amp 60watt LED power supply for 5 meters) or you can use a 12v 8amp 96watt LED Adapter to run 10meters.

Typical led strips are set up for a certain voltage input based on the resistor value included on the strip. You can determine what the voltage you require is from the max current of each of the leds and the resistor value. Many of the strips are setup to use 12V and have a resistor for every 3 leds. Is this the case with your led strip? If so, you need to provide 12V at enough current to drive as many sets of three that you will be using in your strip. Alternatively you can use a constant current supply that matches the current you want the strip to run at. That current will vary greatly by how many sets of three leds you will be driving. A rule of thumb for this type of led is a maximum current of 20mA for each set of 3 leds and resistor.

If you would like to use the power supply you linked to above, it will try to send 1660 mA through the number of led sets you have connected. So, 1660/20 =83 sets if 3 leds to put 20mA through each one. Alternatively, you could use a constant voltage supply, that supplies 12V at 2A and have the same basic thing. With the constant voltage supply, you can use less led sets, with the 1660 mA constant current supply, DO NOT use less than 83 sets of 3.

Oh...and yes, the polarity must be correct for either supply. And yes, wrong polarity could cause damage on the DC side, but not on the AC side of the supply, however, if the AC polarity is wrong, you are creating a dangerous condition. Insulate your connections well on the AC side.

but can a battery device be made, also the sound Output does not need be loud, could one do pressure wave?
Any help thoughts/ideas on this would be really greatful

You might need a 12v 5amp 60watt LED power supply for 5 meters.

hello friend were you able to make led strip? Even I am working on similar project so can you provide led driver? i hope you will help me out..Waiting for reply
