Abstract
A lighting control device for controlling the state and intensity of a lamp includes a user-actuatable intensity selector for selecting a desired lamp intensity level between minimum and maximum intensity levels. The device further includes a programmable microprocessor for storing a preset lamp intensity level, and a linear array of indicator lights (e.g. LED's) for indicating the available range of lamp intensities. According to a preferred embodiment, the microprocessor operates to illuminate all lights in the array when the lamp is OFF, with one indicator light being more brightly illuminated to indicate the preset intensity level. When the lamp is ON, only that indicator light representing the present lamp intensity level is illuminated.
