When power is supplied to an illuminated section(160), the illuminated section(160) is lighted according to a control of the controller(140).

Description

Lighting control device using Bluetooth {APPARATUS FOR CONTROLLING ILLUMININATION USE OF BLUETOOTH}

The present invention relates to a lighting control device using Bluetooth, and more particularly, to control the lighting and turning off of light using Bluetooth, which is a wireless data transmission technology. It relates to the lighting control device used.

Today, with the rapid development of electronic and information communication technology, Bluetooth, a wireless data transmission technology, has been developed. Using Bluetooth, it is possible to transmit and receive data through wireless connection between various communication devices in a PAN (Personal Area Network), home, office, conference room, etc. within a radius of 10m.

Meanwhile, some methods for controlling a lighting device including a conventional fluorescent lamp and an incandescent lamp will be described.

First, as a method of controlling a lighting device, a switch for turning on and off a fluorescent lamp is provided at an edge of a fluorescent lamp, and a long thread is attached to an end to control the switch, so that the user pulls the thread to illuminate the lamp. It can be turned on and off.

However, in the above case, in order to turn on the lighting device in a dark place, there is a problem that the user finds a thread that controls the switch while wandering in the dark for a long time.

Secondly, as a more advanced method than the first method, a switch is usually placed next to the door handle so that the user can light it more easily. However, the above method is inconvenient for the user to come to the place where the switch is directly turned on.

Third, recently developed method is an illumination control method using infrared rays. As described above, IrDA (Infrared data association) for controlling a lighting device wirelessly using infrared rays is automatically turned on when a user approaches the lighting device and turns off after a certain time.

However, the IrDA method has a narrow operating range, and if there is a wall or partition in the middle, communication is cut off, and the lighting is turned off after a predetermined time despite the user's continuous presence.

An object of the present invention is to provide a lighting control device using Bluetooth for wirelessly controlling a lighting device using a computer, a mobile phone, a headset, a remote control, and the like, in order to effectively solve the problems of the prior art.
