Solid State Lighting System
A new innovative solid state lighting system developed for the United States Manned Space Program – is now available to replace the high thermal profile of conventional lamp systems used by the environmental chamber industry for life science research.
Prior to the development of the wavelength specific SNAP-LITE monochromatic solid state lighting system, scientists were faced with the arduous task of trying to filter out all of the unwanted spectral energy from a given polychromatic photon source. This often resulted in a significantly reduced photon energy level at the wavelength of interest. The SNAP-LITE is the first lighting product that can provide wavelength specific photon energy at power levels similar to many of those found in the solar spectrum without the need for filtering.
The SNAP-LITE solid state monolithic lighting technology was developed for the United States Manned Space Flight Program to provide and energy efficient monochromatic light source for illuminating the life science research habitats on board the Space Transport System (STS) and for future habitats being developed for the International Space Station (ISS).
The innovative SNAP-LITE has a patented thermal management system that removes all of the unwanted IR energy before it can contaminate or confound the research lighting application. It has been estimated that more than 80% of the energy load found in most common life science environmental chamber applications is the result of attempting to remove the unwanted IR energy imparted by the light source.
The SNAP-LITE is constructed with the latest state-of-the-art high efficiency Light Emitting Diodes (LEDs). Each 15 x 15 cm (6 x 6 in.) module has a irradiance power output that is continuously variable from 0 to 400 umol/m2 /sec.
The SNAP-LITE monochromatic spectral quality is determined by the selection of wavelength specific narrow band pass LED die. The half power spectral bandwidth is typically +/- 15 nanometers of the peak wavelength.
Bichromatic Spectral Output:
Each SNAP-LITE module has been designed to accommodate two separate channels of wavelength specific LED die in order to provide the means to produce a bichromatic spectral output.
The power of the irradiance and the ratio of spectral mixing can be addressed and controlled in each of the SNAP-LITE modules through a patented Analog Power Buss (APB) distribution system. Each channel of the APB can be addressed through convenient BNC connectors provided on the main power supply. The APB is available in two building block formats, 1 to 9 SNAP-LITE modules and 1 to 18 SNAP-LITE modules.
Pulsed or Flash Operation:
The SNAP-LITE APB has been designed with an innovative feature that allows both channels to be pulsed or flashed independently. This feature has broad applications for florescence or gene expression research. The pulse time has been designed to be computer controlled and has a minimum response time of 0.2 sec.
