Insect vision and sensitivity to wavelength LED Pest control
Human eyes can detect visible spectrum known as rainbow color, define the color of objects by reflection of light − mixture of wavelength.
Wavelength detection of insects: A range of wavelength detected by insects is a little different by the kinds of insects though, most of insects can detect a certain range of wavelength: 285~580nm. Insects response to this range of light, even very low intensity, and gather to light in the distance.
For example, some lamps have lots of insets around while the lights on, but some are not. It is related to wavelength combination that each lamp has, insects are attracted and gathered to lamps which their favorite wavelength composed.
