Kab rhiab heev rau LED teeb wavelengths: Mechanisms, Impacts and Applications

Abstract

With the rapid development of LED lighting technology, increasing attention has been paid to how its spectral characteristics affect insect behavior. This paper systematically reviews insect photoreception mechanisms, the attraction effects of different LED wavelengths on various insects, potential ecological impacts, and LED design strategies based on insect sensitivity. Research indicates that insects show significant responses to light wavelengths between 300-650nm, with ultraviolet and short-wavelength blue light (350-500nm) being most attractive, while long-wavelength yellow-red light (>550nm) tseem nyob nruab nrab. Kev ua kom zoo ntawm LED spectral muaj pes tsawg leeg thiab kev siv zog tuaj yeem txo qhov cuam tshuam rau cov zej zog kab, muab kev tshawb fawb rau eco- tsim teeb pom kev zoo.
