摘要:
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.
摘要:
A lighting control device for controlling the state and intensity level of at least one lamp. The device includes a user-actuatable intensity selector for selecting a desired intensity level between a minimum intensity level and a maximum intensity level, a control switch for generating control signals representative of preselected states and intensity levels of the lamp in response to an input, and a control responsive to the intensity selector and the control switch for causing the lamp to fade from an off state to the desired intensity level when the input from a user from a user causes a single switch closure of transitory duration, such fade occurring at a first fade rate, fade from any intensity level to the maximum intensity level when the input from a user comprises two switch closures of transitory duration in rapid succession, such fade occurring at a second fade rate, and fade from the desired intensity level to an off state when the input from a user comprises a single switch closure of more than a transitory duration, such fade occurring at a third fade rate, each of such fade rates being non-instantaneous.
