lighting geekery: photoacoustic spectroscopy

Brad Koerner

I’m still amazed that after about 20 years specializing in lighting, I can still learn new things that lighting does.  Today’s crazy new thing: Photoacoustic spectroscopy.  Basically, light has enough energy in it to cause material to vibrate, generating acoustic signals that can be measured. I find this interesting because I’ve felt the affect first hand – holding my hand in the beam of a super powerful, crazy-narrow beam LED fixture (which doesn’t have any IR or UV energy in the beam), you can feel the power of the photons.  Mostly what I felt is probably thermal absorption in my skin, … Continue reading lighting geekery: photoacoustic spectroscopy

integrated system technologies

Brad Koerner

ISTL has some interesting multi-protocol, centralized LED driver products available. The White Knight 36 is the world’s first LED driver to integrate an advanced control system alongside a powerful 1000W driver stage, capable of controlling up to 36 independent output channels with the widest ever range of dimming control protocols. The White Knight 36 can be dynamically configured to use DALI, DMX, DSI, RDM, Art-Net3, KiNET & sACN dimming protocols, whilst being able to monitor external occupancy and ambient light sensors without the need for expensive external control systems.
