A large amount of tea is produced every year. Tea is often harmed by pests during the cultivation process, causing great economic damage. In this paper, we simulated a kind of light source for comfortable lighting and trapping pests based on solar-like lighting. We investigated three combinations of white LEDs and monochromatic LEDs for solar-like trapping light. The optimal combination of white LEDs and monochromatic LEDs was determined by the production cost and the spectral phototaxis ratio. We used TracePro for the trapping light mixing design. The results show that the combination of the cold white LED and six kinds of monochromatic LEDs is the best for trapping pests. A light source for comfortable lighting and trapping pests based on solar-like lighting with the color temperature of 7285 k, color coordinates of (0.3052, 0.3031), and color rendering index of 70 is obtained. The trapping light can not only be used as functional lighting but can also be applied to reduce the use of pesticides and improve the quality of tea.
