Abstract: Recently, there has been a growing emphasis on the importance of green industries for reducing energy consumption. As part of the reduction in energy consumption, LED lamps have been widely distributed and used, but conventional fluorescent lamps made of glass tubes have not been actively replaced with LED fluorescent lamps because the replacement of conventional fluorescent lamps is too difficult, for instance, in order to replace the conventional fluorescent lamps with LED fluorescent lamps, a conventional fluorescent lamp stabilizer provided within the light of the fluorescent lamp has to be removed and an LED converter must be installed again.

Abstract: This is a disclosure of a power supply circuit for wall-mounted electronic switches. The disclosed invention is about a power supply circuit for driving circuit inside the wall-mounted electronic switches, which can supply sufficient current demanded by these switch circuits. Recently the functions of wall-mounted electronic switches are being diversified from lamp switching to security, watch, remote control, room temperature control, etc. and the amount of current required inside the switch circuits is increased up to tens of mA. This requires a competitive power supply circuit that can supply a high current. In addition, a space-saving characteristic is also required because the space of a wall-mounted switch is narrow. The invented power supply circuit for electronic switches saves space, supplies a high current, and enhances competitiveness in price and quality, and consequently it makes a considerable contribution to the competitiveness of wall-mounted electronic switches.

Abstract: An apparatus for controlling a lamp with a security function and a lighting control method are disclosed. The apparatus includes a security switch for selecting a security mode, a light emitting diode for displaying security status, a lamp, an illuminance sensor set to a predetermined illuminance value for detecting illuminance of the lamp so that varying time is confirmed according to the predetermined illuminance value, a timer and a microcontroller for receiving an illuminance detection signal if the security mode is activated and controlling the lamp. The microcontroller confirms the varying time twice daily according to the predetermined illuminance value, sets intermediate time between the corresponding twice daily time on a virtual timepiece and turns the lamp on at a specific dusk time period, a specific midnight time period and a specific dawn time period according to the virtual timepiece.

Abstract: This is about the method for performing security function of wall mounted use electric switch and the Switch itself. The invented product comprising Control Micom [U1] in the Switch, luminance sensor, On/Off Key [SW1] and security Key [SW2], operates 24 hr clock based on the outside luminance detected by CDS. The Switch turns off lamps during daytime and turns on lamps during specific night times according to the on/off Timer Program [S108] loaded in the Micom [U1], when the security mode is set on by the users one touch key [SW2], the switch turns on and off lamps according to the users on/off key [SW1], when the security mode is not set. Because users can operate the security Function without a clock setting or time schedules, it is convenient to use. And, because lamps are turned off during the daytime, power consumption is also reduced.

Abstract: A system for electronically controlling a plurality of lighting lamps, comprising a power switch part installed on the same indoor or outdoor wirings of a different place from the lighting lamps, the power switch part supplying alternating current power to the system and performing a switching operation under the control of the user to generate a power control signal, and an electronic lighting lamp control part including a pulse signal generator for generating a pulse signal in response to the power control signal from the power switch part, a pulse signal separator for separating the pulse signal from the pulse signal generator to generate a lighting control signal sensible by the system, a controller for determining, in response to the lighting control signal from the pulse signal separator, whether the lamps are to be turned on or off and turning on or off the lamps in order or all of them at a time in accordance with the determined results, and a power supply circuit for supplying desired direct current
