LED Training and Eliminating Low Quality LED fixtures and modules. Info on CCT, McAdams Ellipse, Xicato Module, and how we at Dasal tackle all the challenges in creating an industry best LED lighting fixture

2. Introduction
 Located just outside of Vancouver BC, product design, testing, production, powder
coating & innovations are all done within our 31,000 sq ft facility. Our specification-
grade architectural lighting products have matured over the years to now include a
multitude of Downlights, Recessed Multiples, Pendant Multiples, Architectural Cylinders
and an ever expanding array of LED products.
 With pride & passion, Dasal continues to evolve by closely studying and thoroughly
understanding how technology is shaping the future of lighting. Coupling our
knowledge with our passion to make it better, along with input from our discerning
clients, we continue exceeding industry standards to ensure years of reliability and
performance in all that we do.
 A constant force behind all Dasal product is our team of dedicated professionals. A
culture enriched with creativity, intelligent customer service, quality control, plus a never
ending quest to exceed expectations, are the spirit of our team

the ability to see
Change in color

10. Knowing that……
How does one effectively use LED’s?

11. Single Point LED’s
• Smaller Luminaire
• Visually Appealing
• Optically easier to control
• Easier to Thermally manage
Ultra Compact Series
Vela & Draco luminaires

12. Multi Point LED’s as Downlights ?
• Visually Unappealing
• Using phosphor converted white LEDs
necessitates usage of individual collimators
over each LED and a dedicated design
• Collimator approach can cause multiple
shadows
• LED’s from multiple bins resulting in
various color temperatures from LED to LED
• If the LED count decreases because of
increasing LED efficiency then a new optical
design will be necessary for the luminaire.
It is not “future proof”.

13. ..If multi Point LED’s are
not the answer for
Higher Lumen
output downlights,
what is……..?

14. Introducing the
Xicato Spot Module

15. Cold Phosphor
Maximizing Robust Life
 “Cold Phosphor Technology” results in higher
efficacies and lifetime of both LED and
phosphor
360o thermal Path
o Reduces heat due to photon recycling
 360o heat conduction
o All surfaces thermally coupled
o Heat conduction from top and bottom of
device
 Results in a uniquely miniaturised module
with relatively low heat sinking demands
700ma Heat Sink

16. Patent pending

mixing cavity Phosphor Technology”
(allowing reduction
of LED count over

temperature and lifetime)
The design of the Xicato Spot Module tackles these challenges and
results in a lighting solution without compromises

17. Remember this ?

20. LM – 80 Test Data – Lumen Depreciation
6000 hrs @ 85oC Case Temperature
Xicato < 2% after 6k hours
Industry Standard

21. Color Maintenance
•Color Maintenance after 5Khours •Corrected Cold Phosphor Technology
•LM-80 test 85o C •Color Stability with Phosphor off Chip
•4000K and 2700K similar •Better Thermal = Better Color Stability

•Each set of points represents a different module under test.
•Multiple data points represent different HTOL test time intervals

26. Every DASAL LED
luminaire undergoes
thorough thermal testing
and performance reviews,
including LM79 testing

27. The Xicato Spot Module integrated into any
DASAL luminaire can be replaced by a future
version with a different LED count without
necessitating any changes
to the optics and uniformity of the luminaire.
