Abstract: An optical film is applied to a side-emitting backlight module. The side-emitting backlight module has a light guide plate for guiding a chief light beam. The light guide plate has a light emitting surface to define a normal direction thereof. The optical film includes a lower prism structure, an intermedium layer, and an upper prism structure. The lower prism structure is disposed on the light emitting surface. The intermedium layer is connected between the lower prism structure and the upper prism structure. When the chief light beam exits from the light emitting surface of the light guide plate, and then goes through the lower prism structure, it goes through the intermedium layer along a changed traveling direction. When the chief light beam exits from the intermedium layer, and goes through the upper prism structure, it turns from the changed traveling direction to the normal direction.

Abstract: A projection screen is adapted to reflect the projection light generated by a projector. The projection screen includes a light absorbing layer, a light reflection layer connected adjacently to the light absorbing layer, and a light transparent layer. The light transparent layer is disposed on the light absorbing layer and the light reflection layer, and has a total reflection surface, a light emitting surface, and a light incident surface connected adjacently to the total reflection surface. The light incident surface provides a theoretical light convergence point, and the light convergence point and the location of the light reflection layer are in mirror symmetry relative to the total refection surface. The projection light enters into the light transparent layer through the light incident surface for refraction, and travels to the total reflection surface for totally reflection, and then to the light reflection layer for reflecting to the light emitting surface.

Abstract: A side-emitting light-emitting element and a packaging lens thereof, wherein the packaging lens comprises an incident surface, a reflective surface, a first refractive surface, and a second refractive surface. The first refractive surface has zigzag surfaces. After a light from a light source enters into the packaging lens through the incident surface, a portion of the light is reflected by the reflective surface to the first refractive surface via total internal reflection to vertically penetrate the first refractive surface and then proceeds along a first optical path. The other portion of the light is refracted by the second refractive surface to penetrate the second refractive surface and then proceeds along a second optical path, which is parallel to the first optical path. A zigzag surface of the first refractive surface avoids from undesired lights reflected by the first refractive surface.

Abstract: A lens of a side emitting LED includes a bottom surface, an incident surface, a reflective surface, a first refractive surface, a second refractive surface and a third refractive surface. An light emitted by a LED enters the lens through the incident surface. A portion of the light is reflected by the reflective surface in an internal total reflection manner to the second refractive surface and emits out of the lens along a first optical path. The other portion of light directly emits out of the lens through the first refractive surface and the third refractive surface. A transitive surface is located between the first refractive surface and the reflective surface. Such a design allows the light entered the lens through the incident surface not cross with the transitive surface. Hence an improper reflection or refraction can be prevented.
