LIGHTING DEVICE FOR EVENLY RETROILLUMINATING FLAT-PANEL MONITORS, COMPRISING A FIBER OPTIC LIGHT GUIDE HAVING DIFFRACTIVE SURFACE ELEMENTS |
摘要 |
The invention relates to a lighting device for retroilluminating flat-panel monitors, such as displays for mobile applications. Said lighting device comprises a light source (14) and a fiber-optic light guide (10). Light emitted by the light source is injected into the fiber-optic light guide (10). The light is ejected on an exits surface (28) of the fiber-optic light guide (10). According to the invention, a surface structure having diffractive surface elements (30) of constant amplitude is provided for the purpose of light propagation on the exit surface (28) of the fiber-optic light guide (10). |
