Abstract

Изобретение раскрывает модуль подсветки, содержащий световодную плиту и множество источников подсветки. Световодная плита содержит множество желобов, которые разделяют световодную плиту на несколько зон. Все желоба имеют особое поперечное сечение, которое по форме может быть треугольным, трапецеидальным или выпукло-изогнутым. Световодная плита может отражать свет, испускаемый источниками подсветки, с помощью особых углов, образуемых особыми поперечными сечениями желобов. Таким образом, возможно полностью решить задачу местного уменьшения силы света модуля подсветки посредством схемы расположения желобов и углов поперечных сечений.
