Abstract
A light guide plate (LGP) and LGP-based flat fluorescent panel (FFP) provides consistent light source for FFP to output consistent and high luminance light source for upgrading general light emitting efficacy to facilitate subsequent use of the light source by expanding incident angle for creating a scattering belt to destroy the total reflection of the light source passing through the scattering belt thus to avail better deflection to reduce light and shade stripes created in subsequent reflection.
Claims6
A light guide plate and a light guide-based flat fluorescent panel, wherein, the light guide plate includes a light outlet surface, a reflective surface, one or multiple light inlet surface;
- and a scattering belt with its surface fogged or roughened is provided on the light outlet surface of the light guide plate.
A light guide plate and a light guide-based flat fluorescent panel, the flat fluorescent panel includes a light guide plate provided with a light outlet surface, a reflective surface, and one or multiple fogged or roughened light inlet surface;
- a reflector adhered to the outer side of the reflective surface of the light guide plate;
- one or multiple diffuser adhered to the outer side of light outlet surface of the light guide plate;
- a condenser disposed externally to the diffuser on the light inlet surface of the light guide plate;
- and a lamp reflector substantially covering up the lamp source;
- and the light outlet surface of the light guide plate is provided with a fogged or roughened scattering belt.
