Some light-emitting LED lens module products, especially the light-emitting LED lens module on the flashlight have different beam colors. It's not using some hidden mechanismto make them look pretty,< /span>Different light colors have different applications. Below is a brief introduction to the most common colors and their practical uses.

White light has perfect color properties, but it impairs low-light-adaptive vision, and it takes a while to reset after the light source is turned offAdapt.

Red light is usually used for night vision. Red light won't cause your pupils to constrict too much, and your eyes don't need to re-adapt to darkness when the red light goes outdarkness. Red is also commonly used in monochrome photo processing as " Safe”Color Because it does not damage the negative being developed, yellow light has some of the advantages of red light and white light. Another advantage of yellow light is that it reduces reflectionsand glare when you read that can cause eyestrain due to prolonged reading.

Green light can also be used for night vision, and green light is especially useful for reading maps or charts at night. It is also not so easy to be detected by night vision equipmentIt is easy to be detected by the human eye, and the brightness of green light is lower than that of red light.

Blue light can be used to read maps at night and is often favored by military personnel because blue light increases the level of contrast. It can also be used as a backstage working light color in theaters and performances.

Blue-green light has night vision advantages similar to green light and blue light, but with the improvement of the color characteristics of blue-green light, some users because of this original Because I like to use blue-green light.

Infrared red light is used with night vision equipment. Otherwise, human eyes cannot see infrared light.

Ultraviolet light is usually used to identify counterfeit banknotes, some UV-emitting LED lens module lighting is very popular in nightclubs and parties,They are used to make fluorescent substances glow brighter.

The color of light and its wavelength

Whether the color of light is visible or not is determined by its wavelength, which is measured in nanometers or billionths of a meter. The light emitted by the luminous LED lens module is almost the same, which means that it is almost always in the same wavelength range and emits very pure colors. Below is the color of light and its wavelength.

Mid-infrared red light4600nm-1600nm--invisible light

Low infrared red light1300nm-870nm--invisible light850nm-810nm-Almost invisible light

White light emitting LED lens modules have yellowish to purplish white light. The color temperature range of white light emitting LED lens modules is as low as 4000°K< span style="line-height:1.5;">to12000°K . Common white light-emitting LED lens modules are usually 6500°-8000° K within the range.
