Definitions

  • the present invention relates to a light-conducting device, and more particularly to a light guide plate which can be widely applied to commercial and domestic practical lighting and decorative lighting fixtures, decorations, handicrafts, exit signs, guide lamps, advertising light boxes and the like. Background technique
  • the design principle of the light guide plate is derived from the liquid crystal display of the notebook computer.
  • the light guide plate uses fluorescent lamps,
  • the CCFL and the LED light source convert the line light source or the point light source into a surface light source through the light guiding point or the light guiding groove calculated by the optical principle, under the action of the reflective film (reflecting plate) and the diffusion film.
  • the reflective film reflector
  • the purpose of the reflective sheet (reflector) is to reflect the light emitted from the bottom surface of the light guide back into the light guide plate to improve the efficiency of light use and increase the brightness.
  • the role of the diffuser film is to make the light more uniform and softer.
  • Light guides are used in a wide range of applications, such as TV backlights, lighting, decoration, advertising, signage, and more.

Abstract

La présente invention concerne une plaque de guidage de lumière (1) dont le dessus présente une image. L'invention comprend la plaque de guidage de lumière (1) et des points de guidage de lumière (2) disposés sur une face de la plaque de guidage de lumière (1). La partie sur ladite plaque de guidage de lumière (1) qui comporte les points de guidage de lumière (2) ainsi que la partie restante (3) qui ne comporte pas de points de guidage de lumière (2) forment ensemble différents textes et/ou images. Cette plaque de guidage de lumière peut résoudre un problème d'éblouissement sans utiliser de matériau de diffusion, ce qui permet une émission directe de la lumière, une réduction de la consommation d'énergie, une amélioration de l'efficacité lumineuse, et une diminution des coûts.
