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
||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.
