AI Technical Summary
Existing light converting devices face challenges in maintaining color stability due to variations in laser peak emission wavelength and temperature, which affect the conversion efficiency and color point of the emitted light.
A light converting device comprising a light converter, a translucent body, and a light coupling structure that decouples the conversion of laser light and transmits a part of the laser light via a reflective top layer, ensuring that at least 80% of the laser light is received by the translucent body and converted to light with a longer wavelength range.
The solution achieves improved color stability by making the intensity of the converted light less sensitive to variations in the laser peak emission wavelength, while also avoiding hotspots and enabling nearly full conversion of laser light, resulting in a stable color point and white point of the emitted light.
