Hey! everyone My name is Steve .

Today i'm going to show you How to Make Extreme Bright USB LED .

I'm using a 10 watt LED chip .

Click Here to See The Video

Let's Start

Step 1: Stuff I Used

Picture of Stuff I Used
  • An Old USB wire
  • Dc to Dc Step Up converter click
  • 10 Watt LED Chip click
  • An Aluminum Sheet

10 Watt LED : It is very small but it can Produce Tremendous amount of light


Dc To Dc Converter : It is used to Convert 5V Dc coming from USB to 9V to Drive the LED


Aluminum Sheet : It is used to Cool Down the led " it's a Heatsink "

Step 2: Attention

i'm using a Very Small Heat Sink

So i'm not going to Drive the Led to it's maximum Power

If you Just Set The Voltage to 9V it's just work fine with little warm up



Step 3: Drilling

Picture of Drilling

  • Drill 2 Hole in Center
  • Keep 3 mm Distance between 2 Holes

Step 4: Converter Mounting

Picture of Converter Mounting

  • Cut Double Sided Tape matching the Dc to Dc converter Length
  • Now Stick the tape to Aluminium Sheet ( As Shown in The Picture )
  • Now Stick the Dc to Dc Converter on the Tape
  • And Remove the excess Tape from the Aluminium Sheet

Step 5: The Solder

Picture of The Solder
  • Now Solder The USB wire to Converter

Connection

  • Negative USB wire to VIN-
  • Positive USB wire to VIN+

If Don't Know Negative & Positive

  • Use Your Multi-meter to Find the Wire
  • Normally it have 4 wire
  • White , Green , Red , Black
  • Black is your Negative
  • Red is Your Positive

All The Best

Step 6: Secure the USB Wire

  • Use a Cable ties to Secure USB wire with 2 Holes

Step 7: Converter Set Up

Picture of Converter Set Up
  • Use your Multi meter and a Screw drive to set the Potentiometer
  • Connect your Multi-meter positive lead to OUT+
  • Connect your Multi-meter negative lead to OUT-
  • Now use your screw driver to tune the Potentiometer
  • Set The Voltage Close to 9 V ( Necessary )

Step 8: Mounting the LED

Picture of Mounting the LED
  • Use some glue to glue the led you can also use silicone based glue
  • Now Connect 2 Wire To Led
  • Negative of Led to OUT-
  • Positive of Led to OUT+

If Don't Know Negative & Positive

  • Just Connect two wire to any terminal of the led
  • now connect your USB to any Source
  • If it Turn On . You've connected The right way
  • if It Does not Turn On . You've connected The wrong way
  • Just Flip the Connection

All The Best

Step 9: Congratulation

You Just Made It

Now Enjoy Your LED

hmmmm very nice

It seems like everyone thinks it doesn't work. You should go into a dark room with your device and take a photograph of the dark room followed by a photograph of the room after powering your device. I'm guessing the two photographs will be different....thanks for sharing your cool idea.

thanks man I already put a picture .

don't do this please, the current is very low!!!

tallemertes (author)2016-12-26

Doesn't the current need to be controlled instead of the voltage on those kinds of LEDs?

obviously the current need to be controlled but in this case i'm just using 70% of it's maximum power no need to controller current .

in simple words it's just "under voltage"

it's just work Fine

Undervoltage doesn't exist speaking about Leds cos voltage is a virtual value, current is the real "physical" value. Generally, in physics, voltage hasn't other meaning than the expression of a current thru an impedance. A constant current generator better fits for Led control. You'll answer that it works as this, sure it does, but in several years, when the Led impedance will change, voltage won't, so power supplied to the Led won't be the same.

Next, on computers, a USB port cannot deliver more than 0.5A, these kind of Leds need 1A (1050mA), I know you're not connected to a computer but confusion still exists as everybody doesn't know that.

thanks for this.

it's only works with 2 amp output
example - mobile adapter , power bank

And, it cannot be extremely bright if not supplied with 100% of the current !

You should add a bigger heatsink. Don't want that LED burning out!

that's why I'm not driving it to it's maximum power.
