Chemical Compatibility
Posted by Paul Laino on Nov 14, 2013

The question frequently comes up, “why would I need a chemical compatibility test kit for our lighting project?” Simply put, items put out vapors and can negatively affect the LEDs. Have you ever smelled wood being cut or that new car smell? Well, you are smelling vapor molecules in the air. These are called VOCs which stands for Volatile Organic Compounds. Most odors and smells are VOCs. The VOCs that we are talking about in this blog usually aren’t the dangerous type which are called Anthropogenic VOCs and those certainly are regulated by law. The VOCs I am referring to are the organic chemicals that have a high vapor pressure which causes a lot of particles to evaporate into the surrounding air. These VOCs can impair the performance and reduce the life of the LEDs. Some items that contain VOCs are glues, rubber O-rings, conformal coatings, paints and gaskets. These VOCs cause a discoloration, or yellowing in the LED luminaire system that neither you nor your customers want to have happen just after installation. The answer is to use a chemical compatibility test kit. Test all components or objects in the vicinity of where the LED will be installed.

 

Creekits.com is a site that you can search for the right kit for your application. Once you find the kit you need, simply select the “Check Inventory” button to be shown which distributors have stock. You may choose any distributor listed for your kit.

Remember, with proper design and adequate testing, chemical incompatibility effects can be minimized or prevented in your solid state lighting design.
