Color temperature and penetration of light

Color headlights’ visible light generally refers to the radiation of 0.38~0.76 micron in the solar radiation spectrum. It is composed of 7 colors such as red, orange, yellow, green, cyan, blue and purple.

Light Wavelength

Different colors of light have different wavelengths, different wavelengths of light, the degree of scattering is not the same.

7 Kinds of Visible light
Light Colors Wavelength (nm) Frequency (Hz) Center wavelength (nm)
Red 780-622 3.8 x 1014 – 4.8 x 1014 660
Orange 622-597 4.8 x 1014 – 5.0 x 1014 610
Yellow 597-577 5.0 x 1014 – 5.4 x 1014 580
Green 577-492 5.4 x 1014 – 6.1 x 1014 540
Cyan 492-470 6.1 x 1014 – 6.4 x 1014 480
Blue 470-455 6.4 x 1014 – 6.6 x 1014 460
Purple 455-380 6.6 x 1014 – 7.9 x 1014 430
Color headlights and Visibility

Light penetration determines visibility in bad weather, such as snowy day, foggy day and so on. It is very important for car headlight and fog light. Before this, Some user of LED headlight respond that their light penetration is insufficient. They think the visibility of the LED light is wrose than halogen bulbs. Based on the above industry knowledge, it is not the type of lamp that determines the penetrability of a light, it’s the color temperature of the light emitted by the lamp.

Choose the right color temperature for your safe driving escort.
