New LED system shines through

Filtering out unwanted spectral energy from polychromatic photon sources requires extensive time and effort. The development of wavelength specific Light Emitting Diode (LED)-based lighting now offers the means by which such filtering is no longer necessary.
New LED system shines through
Many research habitats and environmental chambers, need mono- and bi-chromatic solid-state lighting systems. However, current lighting systems produce high levels of spectral interference that require filtering. The primary problem in filtering unwanted spectral energy sources is that all too often the photon energy levels of the required wavelength of interest are also greatly reduced.

The LED-based development now offers wavelength specific means by which filtering is no longer required. The LED panel can produce photon energy at power levels similar to those found in the solar spectrum. As such, the technology provides a viable lighting source for research environmental chamber habitats.

These panels can produce a dichromatic (red/blue) spectral output. In addition, the spectral mixing - irradiance ratio can be controlled via a PC serial RS485 interface and device driver for NI LabView.

Additionally the lighting system's innovative solid-state reduces the power consumption usually required for filtering unwanted IR-energy. A prototype is available for evaluation and the developers are currently looking for partners in industry or academic or research organisation for a number of collaborations.
