Title: LIGHT-CONTROLLING LIGHT GUIDE BODY AND ILLUMINATION EMITTERS PRODUCED USING SAME
Abstract:
Disclosed is a light-controlling light guide body and illumination emitters produced using the same. The light guide body (1) comprises: a light source incident plane (11) comprising a top vertex and a bottom vertex, the light source incident plane (11) forming a Y-axis of a coordinate system, an X-axis of the coordinate system passing through the top vertex of the light source incident plane (11) and being perpendicular to the Y-axis; a top side surface starting from the top vertex and comprising a number of reflecting units (13); and a bottom side surface comprising a number of light controlling units (15). The light guide body achieves high efficiency for a highly concentrated light source, emits softer light, and provides a user with a more comfortable and natural lighting environment. The light guide body also has the following benefits: glare prevention, highly efficient use of lighting elements, area light formation, and light angle-controlled illumination; further, the invention maintains a high proportion of illumination on one side while generating a secondary ambient light on the other side. Moreover, the light guide body (1) can be used to produce various illumination emitters with different uses.
