    LED lighting offers commercial buildings the opportunity to reduce their energy consumption while improving the light uniformity. The technology that has allowed for these advancements is quite extraordinary and will continue to influence the lighting used in commercial buildings for backlighting and related functions. The comfort of the building occupants and the ability to have lighting without hot spots continue to increase the appeal of LED lighting. Here is how it works.

    What are hot spots and how are they formed?

    Hot spots occur when lighting is not dispersed evenly throughout the light source. These spots can be especially problematic in photography because of how they are reflected on a subject. They can also be uncomfortable or problematic for occupants of a building. When lights do not provide uniform lighting, there can be problems such as people squinting, glares on windows or computer screens. Light sources that provide more consistent backlighting can help provide a higher degree of comfort and make the building more welcoming.

    Why are LED light panels superior for providing uniform lighting?

    Edge lit LED panels or LED lights used in back panels offer a much more uniform light source. Using a semiconductor that converts electrons directly into photons creates LED light. With this system, there is no need for filaments, moving parts, gases, or other parts of the light that increase the odds of the light becoming unevenly dispersed and thus causing hot spots. The LED light panel is a complete unit, instead of having separate pieces like a florescent light. LED lights are also dimmable without losing the quality of the light or experiencing flickering.

    LED lights can also be manufactured to a high level of color consistency, which further reduced problems with the quality of light. The light will also remain the same throughout the lifespan of the light source, rather than degrading as it ages. As LEDs are produced, they are evaluated for lumens, or the color of their light. They are then matched with other LEDs to create an uniform light source. The color mixing of LEDs allows for the light source to obtain a higher color rendering index (CRI) rating. This uniform coloring and the ability of the light source to have an even light spread means that the LED light panel offers a better lighting experience than most other lights.

    Uniform lighting helps to provide a higher degree of comfort for commercial building occupants while also helping to keep energy costs low. Understanding how the technology works and how it provides a consistent light experience can help people appreciate the lighting advancements of LED panel lights.
