A advertisement device for edgelit display with light emitting diode(LED)

摘要

PURPOSE: An edge illumination advertisement device is provided to control the on/off and dimming of each LED(light emitting diode) and to organize a control circuit using a micro controller. CONSTITUTION: An LED module unit(2a) properly mixes red, blue, and green LEDs. An LED variable color control unit(2b) controls the on/off and PWM(Pulse Width Modulation) of each LED by using a micro controller. An LED reflection plate unit(2c) emits various light colors by mixing the lights of the 3 main waves generated from the 3 primary colors LED through the LED control device. The emitted variable color lights from the reflection plate are bent on an advertisement characters engraved in a transparent material plate like an acrylic board. Thus, a display unit(2d) softly displays an advertisement. A light color over 24bit(16,777,216) is changed in a 10msec. Therefore, the edge illumination display unit softly displays the variable color lights and the effectiveness of decoration or advertising is maximized.
