To cope with this, most modern high power LEDs are built upon “remote phosphor architectures”.
Laser-based light sources might be operating in reflection mode, allowing for the remote phosphor to be placed on a reflective surface that can also act as a heat sink to effectively dissipate heat away from the phosphor. Whereas LEDs efficacy has reached 100 lm/W (lumen per watt) to date, laser lighting is able to generate in 2015 about 170 lm/W.
In these LEDs the phosphor is positioned away from the die and the optics is modified to improve light extraction from the LED structure. Laser-based light sources use a similar concept of “remote phosphor”. The phosphor is placed at a distance far from the laser source hence reducing thermal effects and potential colour shifts.
