我们使用的是小型LED阵列(发光二极管)已经调整，以产生在特定波长的近红外光。
We are using an array of small LEDs (light emitting diodes) that have been tuned to produce near infra-red light at a particular wavelength.
可有效地被紫外―可见―近红外光激发，实现上转换和下转换发光，转换效率高。
It may be ultraviolet-visible light-near infrared excited to realize upwards and downwards conversion light emitting with high conversion efficiency.
