Phosphor-Converted Laser-Based Illuminant With High Color Rendering Index and Low Blue Light Hazard

Laser-based illuminant has been a topic of increasing interest in recent years and both color quality blue light hazards are the key issues that need to be addressed. In this paper, performances hazard were investigated by comparing 465 nm laser-excited phosphor materials traditional 452 respectively. Phosphor-converted laser-based (pc-LBI) consisting 465-nm 635-nm LDs (LBI-465) rendering index (CRI) 88.7, which was 8.2% higher than pc-LBI 452-nm (LBI-452). The correlated temperature (CCT) white pc-LBIs ranges from 2200 K 5000 with adjustment red lasers. efficiency radiation (BLHER) LBI-465 is below 0.15, 19% lower LBI-452. results showed high low simultaneously achieved LBI-465. addition, above experimental good agreement simulated results. Based on these results, believed render sources performance boost growth solid-state lighting.
