摘要： An optical device with switchable multiple lenses can be mounted on an electronic device through a connecting module, and provides finely-adjusted alignment with an image capturing lens in any position, and provides a zoom or wide-angle lens for the user to change the focal length and view field of the image. A light-filling/polarizing regulation module to fill light and eliminate unnecessary reflected light to avoid marginal diminishing effect of the image. The optical device includes a viewing device, a connecting module and a light-filling/polarizing regulation module, wherein the viewing device includes a lens module located in the housing and having at least two lenses through which an image captured by the image capturing lens is magnified. At least two lenses has the same lens power, or at least two lenses of different magnifications can be used with the switchable lens seat to obtain the effects of switching different lenses.

摘要： A light control device and method for stimulating plant growth is disclosed. The light control device includes a light source capable of emitting light required for plant growth. The light control device further comprises a plurality of light conversion films rotatably mounted upon a film switching unit arranged around the light source, the film switching unit driven by a motor arranged therewithin. The plurality of light conversion films may further provide a plurality of light spectra required during a plurality of plant growth stages. The light control device determines plant growth stage based on the size and the height of the plants. The motor rotates the film switching unit, based on the plant growth stage of the plants, in such a manner that a light conversion film, associated with the plant growth stage of the plants, is positioned in front of the light source. Such positioning stimulates the plant growth.
