Description

Wall mounted electronic switch means for lighting lamps}

The present invention relates to an electronic wall switch for lighting, and the user can change the brightness of indoor or outdoor lighting by simply touching the touch switch by replacing only the switch attached to the wall without changing the lighting and indoor or outdoor switch wiring. ; 256 steps digital control or [ON]. It allows the user to turn off the incandescent lamp to the appropriate brightness to save energy, and when turning on the array lamp, it turns on from 0% low to 100% high brightness. By greatly reducing the initial inrush current of incandescent bulbs, prolonging the life of the bulb and turning it off slowly when turning it off, it provides a mood increase effect when extinguished, and the surrounding suddenly becomes dark when moving to bed after extinction. It is about eliminating inconvenient discomfort and allowing it to be used with a wide range of input power sources from 80 to 270V _AC .

In addition, the wall switch according to the present invention has an incandescent lamp / fluorescent lamp selection switch can be used for both incandescent lamps and fluorescent lamps, and only add a remote control receiver module to the ON without additional cost increase. There is an advantage that the [OFF] and brightness control can also be remotely controlled.

A conventional wall switch for incandescent lamps [ON] turns on the lamp as shown in FIG. It is configured to use the switch [SW] to turn off the [OFF] and to adjust the brightness using the variable resistor [VR ₁ ] normally associated with the switch [SW]. In the conventional switchgear, the surroundings suddenly become dark when the switch [SW] is off [OFF], so the surroundings are invisible when moving after the switch off [OFF], and the switch [SW] and the variable resistor [VR ₁ ] are mechanical contact methods. Because it is used, it is difficult to guarantee the reliability when used for a long time and there is a disadvantage that can not be used for fluorescent lamps.

The present invention is designed to solve the problems of the prior art, in that the user can control the light by the touch button or remote control only by replacing the switch attached to the wall without changing the lighting and wiring of the indoor or outdoor The incandescent / fluorescent lamp selection switch is placed on the switch so that when the selection switch is in the position of incandescent lamp, the lamp is turned on with the brightness from 0% to 100% when the lamp is turned on. When you turn off the lamp and turn off the lamp, the brightness gradually darkens from 100% to 0% and turns off so that the user suddenly becomes dark when moving after turning off the lights and adjusts the brightness with the touch button. So that the user can adjust the incandescent lighting to the appropriate brightness. When the selector switch is in the position of fluorescent lamp, it turns on immediately when it is ON, and when it is OFF, it turns off [for about 250ms] for a short time and then turns on. 10 seconds] is to provide a 'electronic wall switch for lighting lamps' to eliminate the inconvenience of seeing the surroundings when moving off after turning off completely.
