使用红灯作为停止信号灯可以使更远区域内的驾驶员看见信号。这使得驾驶员们能够及时减速或停车。如果驾驶员直到驾驶地够近才看见停止信号，他们可能不能够及时停车，造成事故。红色也是能够刺激人的颜色，视觉神经对红色反应最为强烈。总之，红灯可以使驾驶员及时停车，避免发生事故。红灯不仅仅用作停止信号，...

Red light therapy is a low-level laser therapy that is a form of photobiomodulation. Photobiomodulation refers to using light to modulate our biology. This process exposes your body to low wavelength red lights that penetrate deep into your skin. Unlike ultraviolet (UV) rays from the sun, ...
6) UV-Visible wavelength 紫外-可见波长补充资料:可见光 可见光visible light 对人眼能起视觉作用的光波。人眼对不同波长的光有不同的色觉,紫光波长最短,红光波长最长。在辐射通量相同的条件下,波长不同的色光对人眼可引起不同的亮暗感觉,人眼对波长为5550埃的黄绿光最灵敏,而对红光和紫光最不灵敏。亦即在引起...
While red light provides a ton of health benefits, including better sleep and restful recovery, it’s made even better when used in combination with near-infrared (NIR) wavelengths. This range of light starts above 780nm and penetrates deeper into the body than any other visible spectrum. ...
