Abstract

A LED advertisement light box of table mode is prepared as using front light transmission board and peripheral external frame to from light box body, setting reinforced strip on four edges in light box body, arranging a complete light-guide plate in light box body and light reflection sheet at back surface of light-guide plate, setting LED light strip at bottom edge of light-guide plate, series-connecting LED in LED light strip then connecting series-connected LED to city power supply through voltage-variation unit.

Description

technical field [0001] The invention relates to electronic technology, in particular to a desk light box technology using LED as a light source. Background technique [0002] Current advertising desktop light boxes generally use fluorescent tubes as light sources. Fluorescent tubes have low luminous efficiency, short service life, uneven light emission, unsafe use, and mercury fluorescent tubes can also pollute the environment. Contents of the invention [0003] In view of the defects existing in the above-mentioned prior art, the technical problem to be solved by the present invention is to provide an ultra-thin, ultra-bright, uniformly luminous, safe, low power consumption, energy-saving, long service life, maintenance-free, and environmentally friendly light-emitting diode advertising light box. [0004] In order to solve the above technical problems, the present invention provides a light-emitting diode advertising light box, which includes a light box body composed o...
