Solid‐state lighting is advancing toward higher power, higher brightness, and smaller size to cope with the market competitiveness, and laser‐driven solid‐state lighting technology is springing up owing to its super‐high brightness and compactness. These developments put forward new requirements for color conversion materials (i.e., phosphors). Here, the state‐of‐art achievements in laser phosphors are summarized, and the topics of luminescence saturation, light extraction efficiency, and light uniformity encountered in laser lighting technology are discussed. Several typical types of color converters, such as single crystal, phosphor ceramics, phosphor‐in‐glass, phosphor films, and quantum‐well light‐emitting diodes, are comparatively overviewed and discussed. The cutting‐edge applications of high‐brightness white laser light in lighting, displays, healthcare, and communications are summarized. The challenges and outlook in laser‐driven solid‐state lighting and some empirical rules for designing novel laser phosphors are highlighted.

“…Most recently, we reported a high-power laser-driven light source that utilizes an array of 445nm violet lasers and an optical cavity to generate visible light for demanding applications such as cinema projectors [1]. Furthermore, Panasonic Corp. has developed a high-power light source that utilizes 405±5nm lasers to excite RGB phosphor layers printed on a rotating wheel producing 60W of RGB light [2].…”

“…Light‐emitting diodes (LEDs) are additional alternatives because of their relatively low manufacturing cost and high performance; they have many advantages such as energy conservation, dc driving, and high luminance. Thus, gas discharge lamps can be replaced by high‐power LEDs in high‐beam headlights …”

“…Thus, gas discharge lamps can be replaced by high-power LEDs in high-beam headlights. [4][5][6][7] A laser beam has several excellent characteristics, including high coherency, high directionality, high purity for a single color, and high optical power (OP) intensity. Therefore, several optoelectronic semiconductor manufacturers, such as Osram, Nichia, and Ushio, have been developing high-OP laser diodes, which can endure high current density.…”

Summary In this study, a laser headlight driving controller (LHDC) using the controller area network (CAN)‐bus communication system was developed and implemented for vehicle headlight applications. To observe temperature variations that influence the forward‐bias voltage and optical power of laser diodes, the laser diode was placed in an ambient temperature‐testing chamber to measure the electro‐optic characteristics and calculate the electro‐optic conversion efficiencies. The optical power and conversion efficiency values obtained at different temperatures (from negative to positive temperatures) when optical power adjustment was executed using analog and pulse‐width modulation technologies were compared. Moreover, a human‐machine operating interface was developed using the LabVIEW software. Therefore, the LHDC and laser optical power can be controlled using a computer through the CAN‐bus communication system to control the LHDC and monitor it.
