CBT-120-UV Product Datasheet
Luminus LEDs benefit from innovations in device technology, chip packaging and thermal management. This suite of technologies give
engineers and system designers the freedom to develop solutions both high in power and efficiency.
Luminus’technology enables large area LED chips to emit
photons uniformly over the entire LED chip surface. The intense
optical power density produced by these UV LEDs facilitate
designs which replace arc and halogen lamps where arrays of
traditional high power LEDs cannot.
For UV devices, Luminus engineers the LEDs to maximize light
extraction and to emit with a Lambertian far-field distribution
pattern. The design maximizes efficiency and allows for flexible
Designed from the ground up, Luminus LEDs are one of the
most reliable light sources in the world today. Luminus LEDs
have passed a rigorous suite of environmental and mechanical
stress tests, including mechanical shock, vibration, temperature
cycling and humidity, and have been fully qualified for use in
extreme high power and high current applications. With very
low failure rates and median lifetimes that typically exceed
10,000 hours, Luminus LEDs are ready for even the most
Thermal management is critical in high power LED applications.
Luminus CBT-120-UV LEDs have the lowest thermal resistance of
any LED on the market with a thermal resistance from junction
to heat sink of 0.73°C/W or 0.88°C/W. This allows the LED to be
driven at higher current densities while maintaining a low
junction temperature, thereby resulting in brighter solutions
and longer lifetimes.
Luminus LEDs help reduce power consumption and the amount
of hazardous waste entering the environment. All LED products
manufactured by Luminus are RoHS compliant and free of
hazardous materials, including lead and mercury.
Understanding Big Chip LED Test Specifications
Every Luminus LED is fully tested to ensure that it meets the high quality standards expected from Luminus’products.
Luminus core board products are typically measured in such a
way that the characteristics reported agree with how the
devices will actually perform when incorporated into a system.
This measurement is accomplished by mounting the devices on
a 40ºC heat sink and measuring the device while fully powered.
This method of measurement ensures that Luminus LEDs
perform in the field just as they are specified.
Multiple Operating Points
The tables on the following pages provide typical optical and
electrical characteristics for the standard drive conditions. Since
the LEDs can be operated over a wide range of drive
conditions(currents from <1A to 30 A, and duty cycle from <1%
to 100%) there are many other potential values attainable.
Driving devices beyond recommended driving conditions
shortens lifetime (see derating curves on page 6).
