US Patent 9157589 LED light having a built-in projection light and night light

An LED light has a built-in projection light and a night light to offer at least two functions for people in a dark environment. The projection light can project an image from any type of display-unit irrespective of geometric shape or image source or type, including display of digital data, wireless digital data, an LCD or TFT screen display, or any other display, enabling images of enlarged size to be projected onto a preferred surface, making it easier for people to see the image. The built-in night light helps people see things in a dark environment.
