What is an LED Module?

If you haven’t yet heard of LED modules, then you don’t know what you’ve been missing out on!

Originally designed for use in advertising signage and channel letters, they are now equally at home in many other indoor and outdoor lighting applications. As you probably know already, LED lighting technology is rapidly replacing the older incandescent and fluorescent forms of lighting due to its greater efficiency and longevity, and LED modules are no exception here. They’re versatile too!

Because each module is connected by lead wiring, they are super easy to cut and re-connect making them suitable for pretty much any project.

Read on to learn more about these lights and their wonderful benefits.

What is an LED light module?

Light Emitting Diodes, or LEDs for short, involve applying a voltage to a semiconductor material so that electrons are knocked loose from the surface of the material, in turn emitting particles of light energy known as ‘photons’.

LEDs are basically a means of converting electrical energy into lights – which they do very well, having a far superior conversion efficiency to the older, incandescent and fluorescent lighting forms. They also possess superior longevity and in many cases are brighter as well. There are fewer environmental issues associated with their disposal as well. Due to their obvious benefits, LED lights are rapidly phasing out incandescent and fluorescent forms of lighting, both in domestic and commercial settings.

Following on from this, an LED – or Light Emitting Diode – module is, simply put, a device containing several LED light bulbs, which is connected to a fixture – containing a battery – that powers all of the individual bulbs collectively; alternatively you plug the fixture containing the bulbs into an external unit that provides the power supply to the LED light module. The module’s material or ‘diode’ is once again an electrified semiconductor material that – depending on the type of material – can emit many different colors, or just white and UV quality light.

Many LED modules, actually known as RGB LED modules, are multi-colored, emitting many different shades of light. This makes them ideal for advertising signage and channel lettering.

LED light modules - applications

As we have seen, the LED module has conventionally been used for the purposes of lighting up outdoor advertising and other shop signage, however, it is also suitable for many other home lighting applications, including:

  • outdoor patio or deck lighting

  • outdoor landscape and accent lighting

  • strip lighting in cabinets, cupboards, drawers and other narrow spaces that tend to be poorly lit

  • strip lighting in your bathroom – for example along the sides of your bath or lining the sides of the bathroom mirror; they provide a nice decorative touch and enable you to achieve customized

  • mood lighting in this, your very own private sanctuary

  • lighting up elements of the dashboard or engine bay in your car or other vehicles

  • reading or night lights – LED modules are perfect if you need a small, focused light by which to read or study late in the evenings

  • LED flashlights and headlamps

LED light modules are very low profile, and easily hidden, however despite this they are capable of creating dramatic lighting effects for both exterior and interior applications. This makes them ideal if you want a small accent light, or to light up areas under the dashboard, or in the engine bay, or your car or other vehicles.

And because the lamps making up the module are connected with lead wiring, they are easy to cut up and re-connect in various ways- in fact with LED modules you can create pretty much any lighting pattern you desire, and you can re-work them to suit the requirements of any particular home project you have in mind

Different types of LED light modules

There are a wide variety of LED modules out there on the market, and they can be categorized in many different ways, whether it is color, form, CCT, module efficiency, packaging type, flux or whether the module contains integrated power. For example, when it comes to ‘form’, the most common forms of LED module are circular and rectangular.

Other common forms are linear, star and square. LED module ‘flux’ or brightness ranges from 105 lumens to about 6000 lumens (the most common numbers are 800 lumens, 1100 lumens, 2000 lumens, or 3000 lumens); as far as module energy efficiency goes, some common values here are 10.8 lumens per watt, 55 lumens per watt, 97 lumens per watt, and 98 lumens per watt.

Some other common categories of a LED light module that are used in signage and advertising include:

  • Side LED modules: used to provide illumination for large-sized sign cabinets

  • Back LED modules: this type of LED module is suitable for internally lit up light boxes and channel letters

  • Flex LED strips: flex LED strips can easily be cut up and recombined into different shapes, making them ideal for intricately worded and designed illuminated signs, as well as acrylic channel letters

As mentioned, some LED light modules to have their own self-contained power supply (in the form of batteries, say), whereas others must be connected to an external power source in order to function.

It goes without saying that if you get yourself a self-contained unit with its own power supply, you have much more flexibility where you place your LED light module than if you purchase a device that requires an external power source.
