2.5. Why most of the competitors are using Lumileds chips?
They are today the best performance chips you can find on the market in terms of performance and durability. On
top of it, they are today the smallest chips you can get: 16x20mm instead of general 35x35mm or even 50x50mm
which was for a long time the automotive standard.
Thanks to this size, they can almost perfectly match the shape and positioning of the filament of the halogen bulb
they replace.
For the X-tremeUltinon gen2, we use exclusive automotive LED chips, which can only be used by Lumileds for
automotive applications.
2.6. Binning of the LED chips. How do we chose them to make sure that we have the same CCT for each PCB?
As a manufacturer of LEDs, we have the knowledge when it comes to the best LED chips possible. All the LEDs
selected to produce our lamps have the exact same color temperature, which means that whenever you purchase
one of them, you’re sure that you get the best light output and homogeneity.
2.7. Why Philips LED don’t have integrated CANbus?
We chose to have separated CANbus for 2 reasons:
1. Most of the time the CANbus is not necessary to install
2. When needed, it’s better to have it separated than integrated because if integrated inside the bulb it
makes the lamp bigger and too expensive. Except for the blinkers where the CANbus is mandatory
(automatically sold with CANbus in the box) so that the blinking is at the right pace, in most cases it’s not
required to fit one. Here below the applications where a CANbus could be/is necessary:
o Turn indicators (front and rear)
o Headlighting (low beam / high beam and Fog)
o Position light
2.8. Is the 24V festoon equipped with CANbus?
They are no CANbus with the 24V festoon, because it’s not needed on all the vehicles. If a CANbus is needed to
avoid error message or blinking, please use the Philips 21W CANbus.
2.9. Is it possible to use the 21W CANbus for 24V LEDs? If yes, how many per lamps is required?
Whether it’s Philips CANbus 5W or 21W, they are not specifically dedicated for one reference. Their purpose is to
increase the wattage of the LED so that it avoids having error message at the front, avoid flashing when the LED
turns on and prevent the turn indicators to blink faster than they should.
2.10. Does the CANbus removes the residual current at the time when the lamp goes off?
The Philips CANbus are designed to regular the amount of wattage within the electrical system before it reaches
the LED. When the LED is off, the remaining power is drawn by the CANbus. So that the LED stays off.
