Abstract

A sound activated light switch, installs in place of the present house light switch, has a circuit that will automatically turn the lights on when a sound is heard. The sensitivity of the sound can be adjusted giving various volumes of noise to operate the switch. When a sound turns the lights on, an internal clock starts counting, each time a new sound is heard, the clock starts back at zero. The internal clock can be adjusted to give various lengths of time for the lights to stay on in the absence of sound. A manual on, off and dimmer knob, when used as the dimmer will put the switch in the sound activated position. In addition, a light sensor is incorporated in the circuit to reduce the sensitivity to sound in daylight.

Description

SPECIFICATION Sound activated light switch This invention relates to a household light dimmer switch.
Light dimmer switches are well known installations in the house and office for where a light can be adjusted to the required level of brightness.
Sound activated switches can be found in toys, such as mechancial dogs that will stop and start when a person claps their hands. Lights are left on when houses are vacant, to keep burglars away and also to see the door lock, garden, doorways and other light switches, when one returns home in the dark. With this invention the light does not need to be on all the time, saving electricity and there is always an element of noise (whether it be on returning to ones house in the dark, or a burglar) to activate the switch.
According to the present invention there is provided a sound activated light switch comprising - a control giving manual on and off modes and an automatic sound activated mode, the later can be adjusted for various levels of light. There is means for making the sound activated mode less sensative in daylight. There are means to turn the switch off in the absence of sound and for adjusting the length of time the switch is to stay on in the absence of sound. All the controls are arranged on a standard British light switch facia panel.
A specific embodiment of the invention will be described by way of example, with reference to the accompanying drawing.
Figure 1 shows the noise inlet 4 to the microphone, the dimmer knob 7, the noise level adjustment screw 1, the time delay adjustment screw 3, the light sensative cell 2, the front facia panel 6 and the wall mounting screws 5.
Figure 2 shows the circuits 8 and the circuit cover 9.
Referring to the drawing Figure 1, the dimmer knob 7 has eleven positions, the two end positions give a manual On and Off control, the middle nine adjust the various levels of light and puts the switch in its automatic sound activated mode, where noise is picked up by the microphone 4, therefore activating the switch.
It is not necessary to have continued noise to keep the lights on. When a sound turns the lights on, an internal clock starts counting, each time a new sound is heard, the clock starts back at zero.
When a pre-set time passes without further sounds occuring, the switch automatically turns the lights off. The pre-set time can be adjusted by rotating the screw 3.
The sensitivity of the microphone can be adjusted by turning screw 1, therefore attaining various levels of noise to turn the switch on automatically. When there is day light the light sensative cell 2, will automatically reduce the sensativity to sound when the switch is in the automatic mode.
1. A sound activated light switch comprising a control giving manual on and off modes and an automatic sound activated mode, the later can be adjusted for various levels of light. There is means for adjusting the sensativity of the sound activated mode, as well as means for making the sound activated mode less sensative in day light. There are means to turn the switch off in the absence of sound and for adjusting the length of time the switch is to stay on in the absence of sound. All the controls are located on a standard British light switch facia panel.
2. A sound activated light switch as claimed in claim 1, wherein a knob turned clockwise or anticlockwise operates the dimmer circuit to control lights to required level of brightness.
3. A sound activated light switch as claimed in claim 1, wherein a screw turned clockwise or anticlockwise adjusts the volume of noise required to operate the switch.
4. A sound activated light switch as claimed in claim 1, wherein a screw turned clockwise or anticlockwise adjusts the length of time the switch is to stay on.
5. A sound activated light switch as claimed in claim 1, wherein a light sensative cell reduces the sensativity to sound in day light.
6. A sound activated light switch as claimed in claim 1, wherein claim 2, 3, 4 % 5 are arranged on the facia panel.
7. A sound activated light switch, substantially as described herein with reference to Figures 1 % 2, of the accompanying drawings.
