The Model 2400B-500-W is a light engine providing high luminous flux,
white LED illumination into optical fibers, bundles and light guides sized
from 3.0 to 5.0 mm in diameter. The product features patented technologies
that encompass non-imaging optics with chip-on-board metallic substrates to
provide both optimum luminous efficacy as well as ideal thermal management.
The 2400B-500-W is ideally suited for endoscope and microscope illuminator applications. The
light engine delivers up to 1500 lumens into a light guide.

Notes:Light Guide Coupling Efficiency
The maximum coupling efficiency for the Model 2400B-500-W requires the use of a fiberoptic or liquid light guide with equivalent specifications for both the nominal values of Numerical Aperture (NA
0) and Clear Aperture (CA
0). When the
light guide design parameters of NAf or CA
f are smaller than the nominal values of the Model 2400B-500-W, the coupling
efficiency is reduced by the square of the ratios, (NAf/NA
0)2 and/or (CA
f/CA
0)2. Other factors that contribute to coupling
efficiency are the reflectance loss at the face of the fiberoptic or light guide, as well as the packing fraction when using a fiber bundle.
Thermal ManagementThe 2400B-500-W uses a metal core circuit board for high thermal conductivity that allows heat to dissipate in all directions. Reduced overall thermal resistance results in increased LED performance. When thermal energy generated exceeds the thermal energy dissipated, an additional means of cooling may be required to maintain LED performance. Some applications cannot efficiently dissipate enough heat from the circuit board alone and an external heat sink is recommended. The external heat sink is an efficient and inexpensive method of extending the surface area necessary to dissipate heat generated by the LED array. The 2400B-500-W circuit board features an attached thermal pad for heat sink contact, no thermal grease is needed. Adding the feature of forced air convection across the heat sink fins removes heat faster and more efficiently. This feature is often necessary when ambient airflow is limited or non-existent. Every 2400B-500-W circuit board has a built-in thermistor for temperature monitoring. Lifetime of the 2400B-500-W unit operated continuously would be compromised if the temperature of the circuit board exceeds 60°.
