Clean Room Lighting - How To Prevent Contamination

  • 18, 06, 2021

In clean rooms, to prevent contamination, all the materials, and components, including lighting, must be germ-free. Therefore, cleanroom lighting not only provides visibility but also meets rigorous cleanliness requirements. 

When it comes to choosing the right lighting system, a major consideration is price. Energy bills, initial costs, and maintenance costs all contribute to the decision-making process for clean room lights. That said, lighting takes less than 1% of total clean room energy consumption, so lighting maintenance is not a significant concern.

Clean rooms demand different lighting levels depending on the various processes that take place there. Here is where a professional designer comes in handy: he can decide on what lighting levels are required for different clean room tasks.

A bigger consideration is the air supply system. In some clean rooms with high cleanliness class, air handling system leaves no room for lighting installation. That said, a well-organized design process can result in an efficient solution for better lighting in your clean room in most cases. 

Most cleanroom lighting applications call for fluorescent lamps because they are energy efficient, are easy to maintain, and have a long lifespan, but other types of lighting are appropriate in clean rooms as well. Incandescent, high-intensity lamps and LED light fixtures are found in cleanroom lighting applications.

Lighting systems can utilize many different lamp types.

  • Incandescent, high-intensity discharge, and fluorescent lamps are most commonly used in commercial and industrial facilities.
  • Fluorescent lamps are popular in clean room environments due to their energy efficiency, low maintenance, and long life span.
  • Light fixtures with high UV levels are being used to reduce bacteria and other contaminations.
  • Recently, more and more clean rooms use LED panel lights for their long life span and high efficacy.
