Backlighting is used in a wide variety of manufacturing applications, including the production of human machine interfaces (HMIs), switches, keypads and more. The term “backlighting” simply refers to the process of illuminating an area from behind that area. Normally, this is achieved using one or more lighting devices, such as electroluminescent (EL), fiber optics or light-emitting diode (LED), the latter of which we’re going to discuss in this blog post.
Advantages of LED Backlighting
One of the greatest benefits of LED backlighting is its long lifespan. Depending on the specific type and how it’s used, an LED backlighting solution may last for 50,000 hours — sometimes even more. Whether it’s used in a factory, distribution warehouse, retail store or elsewhere, LED backlighting has an incredibly long lifespan, allowing business owners to get more bang for their buck.
Just like LED fixtures are more energy efficient than incandescent and compact fluorescent lighting (CFL) fixtures, LED backlights are also energy efficient. In fact, they are among the most efficient types of backlighting. As a result, companies can save money on their electricity bills by using LED backlights in their HMIs and devices.
A benefit of LED backlighting that’s often overlooked is its minimal production of heat. All backlights produce some heat, and LEDs are no exception. However, LEDs produce significantly less heat than other types. This makes then easier on an HMI’s or device’s components. With less heat generated, components aren’t susceptible to heat-related damage. Furthermore, this reduces the risk of fire and explosion.
Disadvantages of LED Backlighting
So, what are the disadvantages of LED backlighting? Well, there really aren’t many. Some of the lower-quality LED backlights may suffer from bright spots. When used for a long period of time and not turned off, LED backlights may create uneven illumination in which one area is brighter than another area. But even this can be avoided by choosing a high-quality LED backlighting solution from a reputable company.
In Conclusion
LED is an excellent backlighting solution for any device or application that requires rear illumination. They have a long lifespan, are energy efficient and doesn’t produce much heat. Of course, there are other backlighting solutions to consider, such as EL and fiber optics. When shopping for a backlighting solution, consider all options and choose the one that’s right for your company’s needs. As revealed here, however, you really can’t go wrong with LED backlighting.
