ABSTRACT:
An electrical timer which controls the ON-time of a light bulb circuit hooked up to a power source by way of an ordinary power switch. Usual operation of the timer is such that, when the power switch (which is initially OFF) is turned ON by a person, the light bulb which is connected to the switch by way of the timer will first turn-on FULL brightness for a period of time, after which it will DIM-down to about 30 to 50 percent brightness. In a fundamental version of the timer, the light bulb will remain in the dimmed-down mode until a person turns the light switch OFF. Another version allows that after a period of time in the dimmed-down mode, the light bulb will be fully shut OFF by the timer. The dimmed-down mode may also be arranged to occur in two or more level steps, i.e. part-DIM and full-DIM for example, with each step having a finite and substantial duration. A touch-strip may also be provided in which, when "touched" by a person, body capacitance serves to reset a dimmed-down light to full-brightness. The solid state modular timer may work in conjunction with any ordinary " two-terminal" wall-type electrical switch, such as commonly used in building construction.
