Claim Text:
1. An LED module comprising: a printed circuit board (PCB) or a surface mounted device (SMD) carrier; an LED die mounted directly or indirectly to a top surface of the PCB or SMD carrier; an optical element arranged on top of the LED die; and a white reflective layer covering an area of the top surface of the PCB or SMD carrier which surrounds the LED die on which said optical element is arranged, the white reflective layer contacting sidewalls of the LED die; wherein the white reflective layer has a thickness that is less than a thickness of the LED die when viewing the LED module from a side, such that the white reflective layer does not extend above a top surface of the LED die when viewing the LED module from the side, and wherein the thickness of the white reflective layer is between 20 μm and 200 μm measured from the top surface of the PCB or the SMD carrier.
