The Applications of the LED PCB

The light-emitting diode (LED) is an electronic component that is made up of a highly doped semiconductor material, usually silicon and germanium.

LEDs emit light energy when a certain level of current passes through them.

They are made up of a p-n junction, just like a normal diode, but the difference is that normal diodes do not emit light energy whereas LEDs do.

LED PCBs are widely used in electronic circuits.

Whether you are a student, an electronic enthusiast, or a working professional, you must have worked with LEDs many times.

They have many applications, and you will find them in almost every other circuit. Let’s see what the applications of LEDs are.

Indicators:

LEDs are most commonly used in electronic circuits as indicators.

For instance, LEDs are used to show whether your computer monitor has is turned on or off.

A red light indicates that the monitor is OFF, while a green light indicates that it is on.

Moreover, LEDs are used in handheld torches, emergency lights, and cap lamps used by mining professionals.

These lamps last a very long time and are robust, so you cannot easily break them.

LEDs are also used as backlights in TV displays and monitors these days.

The warm and calming lights present inside the airplane cabins are also LED lights.

They help provide a warm, cozy, and relaxing environment for the passengers.

The applications of LED as an illuminator have grown significantly and will hopefully keep on growing.

Data Communication:

LEDs are also used for data communication, such as the transfer of information.

Optic fiber technology uses LEDs to send information from one place to another.

Moreover, visible light communication (VLC) uses LED as the main information transfer medium because LEDs provide a high data bandwidth that helps communicate effectively.

Machine Vision Systems:

A great example of machine vision systems using LED is a barcode scanner.

Typically, a red LED is used in barcode scanners which you must have seen in supermarkets and grocery stores.

The fact that LEDs are a source of bright light and are compact in size, makes them a great fit for machine vision systems.

1. The advantages of LED PCB
With the electronic products is more and more smaller and thinner, making it popular to use LED PCB, and there are various advantages with using LED PCB as follows:

• Lightweight, low profile
• dimensional stability
• thermal expansion
• heat dissipation
• Lower cost backlit membrane switch
• Dust and moisture resistant
• Make it easy to integrate into complex interface assemblies
• Efficient low power consumption
• Available in a wide variety of sizes, colors, and intensities
• May be used in silver flex membrane switches and copper flex membrane switches.

There are two main reasons which make the LED PCB be popular in addition to increasing the light output of the fixture with integrating multiple LED components.

1. It’s easy to tune the color function by integrating the LED components with different color temperatures or different colors into the same PCB.
2. It can achieve the various light fixtures to meet different lighting requirements with the boards that have different shapes, sizes and materials.

2. SMD LEDs in your PCB
There are many devices including LEDs on a PCB using surface mounted components.
If the wires are quite thin, through hole components can bend slightly so that it looks cheap from the outside.
If making it right to solder the SMD LED, it will be rigid on the board. What’s more, it can also place the SMD LED behind a screen, and cheaper LED that use a bulb will stick out through the packaging.
So it can place the SMD LED behind a small screen in your packaging to be cleaner for your device.
As you know, many PCBs that contain LEDs are fabricated with multilayer FR-4 substrates, so you need to have a pattern of closely-spaced filled or plated through vias under each component so that it can transmit heat, as well as get to your power and ground layers.

If your LEDs have a small footprint and are surfaced mounted, it can use our vias.
Probably there will be a weak solder joint or even tombstoning because it doesn’t fill or plate over the vias and then solder can wick into the vias during assembly, so the reason why it’s better to just use SMD LEDs on an LED lighting array is that the problem with wicking.
A single LED with decent power output will not lead to damaging to your board because of undue thermal.
However, if you are going to have a system for lighting applications, it will need to suffer from a massive heat for the board that supports your LEDs, and make it hard to cool with traditional methods for the boards.
Because the individual LEDs are too small, you can’t really attach a heatsink anywhere, and a heatsink will block the emitted light anyways.
Because there is a great demand on thermal, the boards with a metal core are usually used in LED lighting applications due to their ability to dissipate a great deal of heat.
In general, aluminum is used for LED lighting applications as the metal core in PCB.
What’s more, aluminum is the most metal used as the core among all the possible metal core PCBs.
As well as copper and iron are used for metal core PCBs.
