Enhanced Illumination Efficacy of White Color from Green Laser and Magenta Phosphor

摘要

Techniques related to generating daylight-like light from green laser and magenta phosphor are disclosed. Such light may be used in headlights of vehicles. The daylight-like light generated from green laser and filtered through magenta phosphor is almost white or substantially white. The white laser is generated from green laser that is filtered through magenta phosphor. The green laser is well known for producing the highest perceived intensity among all colored lasers with equal or similarly provided energy and is low to obtain in cost.

主权项

1. An apparatus comprising:
a laser source to generate green laser; magenta phosphor provided to filter the green laser to generate white laser, wherein the magenta phosphor is produced by mixing two different types of phosphor; and an optical diffuser to diffuse the white laser to produce white light beams.
