ABSTRACT:
A visual messaging system and device can employ high efficiency LEDs and current driven versus voltage driven circuits to reduce power consumption and enable the device to be powered from IEEE 802.3af (Power over Ethernet (PoE)) standard based power sources. The device can be powered from a local area network (LAN) connection using PoE, and does not require a separate AC power supply. The present invention also uses a 1× yellow algorithm to create the yellow color with one half the instantaneous current of previous circuits. The device can incorporate multiple message inputs for receiving and displaying messages having different priorities, allowing higher priority messages to override lower priority messages.
