Color and the wave length of LED lights
Sep 09, 2021
Whether the color of light is visible is determined by its wavelength. The wavelength of light is measured in nanometers, which is one-billionth of a meter. The light emitted by the light emitting diode is almost the same, that is to say, wavelength of the light is almost the same, and color is very pure.
The different emitting colors of LEDs is corresponding to a certain light wavelength range, and the colors almost cover the solar spectrum. At present, ultraviolet, blue, green, yellow, red, infrared and UV free light-emitting diodes have been successfully prepared. In addition, LEDs are with advantages of low operating voltage, low operating current, and easy to assemble, which make them a new generation of energy-saving and low-carbon light sources. LIGHT VICTOR LED lamps can be energy saving over 75%.
The following is the color of light and its wavelength.
Mid-infrared red light
4600nm to 1600nm—invisible light
Low infrared red light
1300nm to 870nm—Invisible light; 850nm—810nm—almost invisible light
Near infrared light
780nm—A very light cherry red light can be seen when directly observed
770nm—A deep cherry red light can be seen when directly observed
740nm—Dark cherry red light
Red light
700nm—dark red; 660nm—red; 645nm—bright red
630nm to 620nm—orange red
Orange light
615nm—red orange light; 610nm—orange light; 605nm—Amber light
Yellow light
590nm—sodium yellow; 585nm—yellow; 575nm—lemon yellow/light green
Green
570nm—light turquoise; 565nm—turquoise; 555nm—550nm—bright green; 525nm—pure green
Blue green
505nm—cyan/blue—green; 500 nm—light green cyan; 495nm—sky blue
Blue
475nm—Azure Blue 470nm—460nm—bright blue
450nm—pure blue
Blue purple
444nm—dark blue; 30nm—blue purple
Purple
405nm—Pure Purple; 400nm—deep purple
Near Ultraviolet Light
395nm—deep purple with reddish color
UV—A type ultraviolet light
370nm— is almost invisible light, it appears a dark purple when filtered by wood glass.
White light emitting diodes have yellowish to purplish white light. The color temperature range of white light emitting diodes is as low as 4000K to 12000K. Common white light emitting diodes are usually in the range of 6500K to 8000K.
