Abstract
The combination of LED lighting and particulate detectors are enhanced by exploiting the light degradation/reflection/wavelengths detected, absorbed or frequency shift seen in lighting due to the presence of smoke, gas or other molecules (such as explosives) in the air can be detected. The use of LEDs is expanded well beyond simple lighting and energy savings to include not only smoke and fire detection by also to scan for gases and particulates found based in the usage environment.
