A front light module includes a light guide sheet and a light bar. The light guide sheet has two light receiving laterals, a fold line, a first pattern area, and a second pattern area respectively located on two sides of the fold line. One light receiving lateral is protruded to form first taper sets, and the other is protruded to form second taper sets. The second pattern area is superimposed on the first pattern area, and the first and second tapers set are engaged and coplanar to form a light incident surface after folding along the fold line. The light bar provides light toward the light incident surface, the first pattern area is lit by the odd positions of the light bar via the first taper sets, and the second pattern area is lit by the even positions of the light bar via the second taper sets.

Terminals engaged light guide plate and front light module thereof

A light guide plate provided for a luminous keyboard is disclosed. The light guide plate includes a main body, a first bump pair, a second bump pair, and many microstructure patterns. The main body has a light output surface and many press button installation areas defined thereon, each of the press button installation areas is arranged to fix a press key structure. The first bump pair and the second bump pair are integrally and seamlessly protruded from the main body. Each of the first bump pair has a first recess, and each of the second bump pair has a second recess. The first recess and the second recess are configured opposite to each other, and provided for assembling the press key structure. The microstructure patterns are formed next to the first and second bump pairs to abstract light by destructing the total reflection in the main body.
