It is interesting to figure out the reasons behind the changing Osram to Philips by Apple in its LED lighting component supply.
Normally we would associate it with some reasons such as;
3. Technological advancement and stability
4. Size of component
Our key interest lies in whether Philips Lumileds division has a much superior LED chipset at a lower cost compared to Osram.
These days we have LED efficacy achieving 160 - 180 lumens/watt. This means in general; we can use less electricity to achieve a brighter effect. The concern in my opinion will usually be in the heat dissipation, especially when it comes to end consumer electronic devices.
I've often accidentedly turn on the flash light function when the phone is in my pocket. Within 1 - 2 minute, i can usually feel a heat source on my thigh. We'll probably need a sensitive LED to know when they should light up and when not to. This brings me to the point of smart lighting. With Apple and Cisco tying up to trial on light fidelity, it may be possible to rope in the expertise of Philips and it's Lumileds know-how.
