Improved light engine

A light engine configured to generate engine light and comprising:

• a first laser arrangement configured to emit first blue laser light;
• a second laser arrangement configured to emit second blue laser light;
• a first mirror arrangement being partially reflective for the second blue laser light and partially transmissive for the second blue laser light and configured to split the second blue laser light emitted by the second laser arrangement into a first part of second blue laser light and a second part of second blue laser light, wherein the ratio of the first part of second blue laser light to the second part of second blue laser light is in a range from 0.1 to 2;
• a beam combiner arranged downstream of the first mirror arrangement and configured to combine the first blue laser light and the first part of second blue laser light and to direct the combination of the first blue laser light and the first part of second blue laser light to a phosphor element;
• the phosphor element arranged downstream of the beam combiner and configured to receive the first blue laser light emitted by the first laser arrangement and receive the first part of second blue laser light, and convert the first blue laser light emitted by the first laser arrangement and the first part of second blue laser light into converted light, and wherein:
• the light engine further comprises a diffuser configured to diffuse the second part of second blue laser light, and
• the light engine is configured to collimate the converted light emitted by the phosphor element and to combine the collimated converted light with the second part of second blue laser light emitted by the second laser arrangement to generate the engine light;
• and wherein the engine light is white light having a correlated colour temperature in a range from 2700 K to 10000 K, preferably in a range 5000 K to 10000 K, and a colour rendering index of at least 70, preferably at least 80, more preferably at least 85, most preferably at least 88.
