Demonstration of a blue laser-induced phosphor-coated white light prototype

The blue laser-induced white light is a promising candidate to revolutionisethe luminous intensity of the white light by several orders of magnitude as compared with the existing blue light?emitting diodes-based white light. This emerging technology has an extremely bright future with endless uses of tunable power of the laser that controls the intensity of the emitted white light for several applications such as headlights in automobile industries, rail engines, playgrounds and many more.

CSIR-National Physical Laboratory (CSIR-NPL), New Delhi, has designed and developed a prototype device based on a phosphor?incorporated Sapphire Disc (PISD) which on excitation by a blue laser diode produces highly-efficient white light. The CSIR-NPL has developed this prototype under a consultancy project entitled “Development of YAG:Ce yellow phosphor integrated with blue diode laser to produce white light for a car headlight application" funded by Fiem Industries Limited, Sonepat-Haryana, India.

This new approach provides a paradigm shift to produce highly-efficient white light based on PISD integrated with a blue laser diode as compared with the conventional technology. Fiem Industries conducted a joint meeting of industries collaborative discussion (Yamaha, Japan and Fiem) for futuristic lighting systems development and related demonstration on 13 October 2021 for automobile headlights with leading international two-wheeler company Yamaha, Japan at Fiem Industries Limited, Sonepat,Haryana, India.

CSIR-NPL and Fiem Industries Ltdjointly presented and demonstrated a prototype based on Laser Assisted Remote Phosphors (LARP) white light generation for automotive lighting for automobiles. This joint effort is a stepping stone towards Make in India (Vision of Nation) for future technology based on Blue Laser Induced White light.
