Title:
EMBEDDED LIGHT EMITTING STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2020/094024
Kind Code:
A1
Abstract:
An embedded light emitting structure, comprising a light source (1), a light guide plate (2), and a light intercepting member (3). By providing a light condensing groove (11) on the light guide plate (2), light transmitted laterally in the light guide plate (2) are intercepted out of the light guide plate (2) in high proportion, so that in the process of passing through the light condensing groove (11), the light transmitted laterally in the light guide plate (2) are intercepted into invisible light projected in two directions, i.e., laterally penetrating through a width direction of the light condensing groove (11) in the original direction and entering the light guide plate (2) again to maintain the lateral transmission, and laterally penetrating through a thickness direction of the light guide plate (2) and being not able to enter the light guide plate (2) again for transmission; and the invisible light projected from the light condensing groove (11) are intercepted and received by using the light intercepting member (3) connected to the light condensing groove (11), and converted into high quality visible light having a corresponding light emitting pattern in a longitudinal direction. The structure is simple, the assembly is fast, the overall size is thin and delicate, and the light emitting effect is good.
