LED drivers convert your power supply to constant current, suitable for "Led light hook up," helping to maximize the energy potential. Optics control the illumination pattern, either diffusing it or focusing it as your application requires. Heat Sinks and housings give your project a clean enclosure while maintaining a low temperature. Power supplies allow you to power your LED and driver from a wall outlet or other source.
LED lighting accessories include seals for coating electronic components, premium adhesives, switches, battery-holders, wire, power connectors, soldering irons and more. Linear LED strips are ideal for general lighting, sign or channel letters, architectural lighting and more.
LED Supply offers a complete lineup of LED kits that save you time and Led light hook up a successful end result for your lighting project. Hopefully those looking for practical information on electrical circuits and wiring LED components found this guide first.
With years of providing LED education, training and explaining the electronic circuit concept to customers, we have gathered and prepared all the critical information needed to help you understand the concept of electrical circuits and their relationship to LEDs. Lets get Led light hook up with the most basic question…. The requirements of a lighting application often dictate what type of circuit can be used, but if given the choice, the most efficient way to run high power LEDs is using a series circuit with a constant current LED driver.
Running a series circuit helps to provide the same amount of current to each LED. When each LED is receiving the same current it helps eliminate issues like thermal runaway. The image to the right shows an example: To wire a series circuit like the one shown, the positive output from the driver connects to the positive of the first LED and from that LED a connection is made from the negative to the positive of the second LED and so on, until the last LED in the circuit.
Finally, the last LED connection goes from the negative of the LED to the negative output of the constant current driver, creating a continuous loop or daisy chain.
Here are a few bullet points for reference about a series circuit:. The loop concept is no problem by now and you definitely could figure how how to wire it, but how about powering a series circuit. This means you have to supply, at minimum, the sum of the "Led light hook up" voltages of each LED. Lets take a look at this by using the above circuit again as an example and lets assume the LED is a Cree XP-L driven at mA with a forward voltage of 2.
The sum of three of these LED forward voltages is equal to 8. In the beginning, we mentioned using a constant current LED driver because these power modules can vary their output voltages to match the series circuit.
For a deeper understanding of LED drivers take a look here. Hopefully you are able to find a driver that can accomplish your LED circuit with the diodes in-series, however there are circumstances that might make it impossible.
Sometimes the input voltage might not be enough to power multiple LEDs in-series, or maybe there are too many LEDs to have in-series or you just want to limit the cost of LED drivers. Where a series circuit receives the same current to each LED, a parallel circuit receives the same voltage to each LED and the total current to each LED is the total current output of the driver divided by the number of parallel LEDs.
In a parallel circuit all the positive connections are tied together Led light hook up back to the positive output of Led light hook up LED driver and all the negative connections are tied together and back to the negative output of the driver. Lets take a look at this in the image to the right.
Using the example shown with a mA output driver, each LED would receive mA; the total output of the driver mA divided by the number of parallel strings 3. Lets start Led light hook up the series part of the circuit. However, 12V dc is enough to run three in-series 3 x 2.
And, from the parallel circuit rule number 3 we know that total current output gets divided by the number of parallel strings. So, if we were to use a mA BuckBlock and have three parallel strings of 3 LEDs in-series, then the mA would get divided by three and each series would receive mA. The example image shows this set-up. Varying voltages across separate strings results in the current not being divided equally.
When one string draws more current than another, the LEDs being overdriven will heat up and their forward voltages will change more, resulting in more unequal current sharing; this is called thermal runaway. We have seen many circuits set-up like this work well, but caution is required. For more information on this concept and ways to help it current mirror there is a great article here within LEDmagazine.
