The present invention relates to a security lamp socket, which has a dimming control function, which comprises: a body; a bolt unit which is formed on the top surface of the body to receive power from the outside by being combined with an existing socket; a nut unit which is formed on the bottom surface of the body; a GPS antenna which is formed in the side of the body to selectively supply power to an SMPS of the security lamp which is combined with the nut unit through a printed circuit board inside; a GPS module to receive a GPS signal from GPS satellites through the GPS antenna installed to the side of the body; a microprocessor to receive the GPS signal from the GPS module through a RS232 modem; and a contact driving unit to control the supply of power by calculating the current time of the location in which the security lamp is installed. The microprocessor performs dimming control using a simple power line communications method by transmitting a dimming control signal to the SMPS of the security lamp through a modulation unit of tone generator. |
