Description

Digital control lighting using touch wall switch {.}

The present invention relates to a digital control light using a touch type wall switch, and the user can digitally control the brightness of indoor or outdoor lighting in multiple levels (for example, 256 steps) only by operating a touch switch attached to a wall. Lower the brightness to save energy, and when you turn on the lamp [ON] to turn on the light from about 40% to 100% of the brightness by significantly reducing the initial inrush current of the lamp to extend the life of the lamp and lighting When you turn off [OFF] is about 40% of the brightness to 0% of the brightness to turn off gradually to go out to sleep after going out of the darkness suddenly dim around to remove the invisible discomfort.

Looking at the conventional lighting, the indoor lighting is turned [ON]. ON to be attached to the wall to turn OFF. OFF [ON] by raising or lowering the [OFF] switch. Turn off [OFF]. At this time, when there are several light bulbs (3 to 7 or more) in the lamp, all the light bulbs are turned on or off. When you want to lower some of the bulbs to turn off the inconvenience is to turn off. In addition, when the lamp is turned on [ON], the inrush current of the bulb is very large (normally 10 times normal operation) has a disadvantage of shortening the life of the bulb. On the other hand, when the lamp is turned off [OFF] completely off, when moving to bed after the lights out, the surroundings suddenly become dark and invisible.

The present invention is designed to solve the problems of the prior art as described above [ON] to turn on the lamp only by the operation of the touch-type wall switch. In addition to controlling the OFF [OFF], the brightness of the light can be adjusted in multiple stages, contributing to user convenience and energy saving. To extend the life and to turn off when it goes off after a certain period of time when off [OFF] to provide digital control lighting using a touch-type wall switch that eliminates the inconvenience of suddenly dark when moving to bed have.
