An illumination system for mobile dispensing devices is disclosed. An acceleration sensor detects the acceleration of the device and a microcontroller analyzes the acceleration to determine if motion and tilt are present. If motion is greater than a threshold value, then side lights turn on at maximum brightness. Once motion is equal to or less than the threshold level, the side lights will progressively dim over a configurable period until being turned off. If the tilt angle of the device is greater than a configurable value from its vertical position, the top lights turn on at maximum brightness. Once the tilt is below or equal to its configurable value, the top lights will progressively dim over a configurable period until being turned off. If either the motion or tilt angle become greater than the programmable value during the dimming process, the corresponding light will again be illuminated at maximum brightness. |
