- 摘要：
he present invention relates to an electric light projector-and-mirrors combination adequately positioned in fields or cultivations for fighting frost. The projector emits electric light to plants and the mirrors, which are properly placed into thecultivation, reflect the incident rays. A field of luminous rays is formed over the cultivations to impede the formation of frost over the plants and soil surface. Additionally, the installation of successive mirrors on both sides of a street enables the illumination thereof at considerable length, with the use of a few light-emitting devices. Compared to the previous state of art using expensive installations of frost-preventing systems (artificial rain or wind-mixing devices), the invented construction utilizes readily positioned devices, at low operational cost.
