  • Lighting indicating device having plural illuminating elements with all such elements being illuminated with one being greater than the others
    Patent number: 5399940
    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.
