Abstract
The high intensity light output of edge lighting point light sources such as LEDs may generate undesired leakage light that is optically conducted by way of a continuum of the material of a components affixing adhesive member. In accordance with present disclosure, air filled grooves or other such discontinuities are formed in the adhesive member along respective light output pathways of the respective point light sources. One corresponding embodiment comprises spaced apart LEDs mounted on an FPCB; a light guide plate (LGP) disposed adjacent to the LEDs; a main support accommodating the LEDs and the LGP; and an adhesive member formed to affix together the FPCB, the main support, and the light guide, wherein the adhesive member is patterned to define air filled grooves along respective light output pathways of the LEDs.
