In addition, in the present invention, the communication between the LED stand 100 and the external device 200 may employ, for example, a profile such as A2DP (Advanced Audio Distribution Profile), HFP (Handsfree Profile), SPP (Serial Port Profile), or the like. Can communicate in both directions.

Hereinafter, the operation of the LED stand of the present invention configured as described above will be described with reference to FIGS. In particular, FIG. 3 is an enlarged view of a portion where various functions are printed in the LED stand shown in FIG.

 Since the LED lamp unit has the same parts and functions as in the prior art, a detailed description thereof will be omitted. In addition, the LED lamp unit can be operated separately without interworking with Bluetooth and FM radio.

The Bluetooth unit 104 functions as an audio unit of the Bluetooth unit, and the music of the external device 200 (or a Bluetooth-embedded audio device) such as a smart phone according to the present invention according to the transmission standard of the A2DP profile of Bluetooth. Received by the stand 100 can listen to music through the speaker / earphone unit 109 built in the LED stand. At this time, when a call is received to an external device 200 such as a mobile phone when listening to music, it can be received by the hands-free function built in the LED stand 100 of the present invention. The external device 200 includes all smartphones (for example, iphone / Android Phone) and Bluetooth built-in devices currently on the market.

3, in order to operate Bluetooth, the Bluetooth mark is turned on when the Bluetooth mark of the LED stand is touched. If a call is received by a mobile phone, the phone mark blinks. To receive this, the phone mark can be received by touching the phone mark shortly (less than about 1 second), and the phone mark lights up. In addition, if you want to end while receiving hands-free, you can touch the phone mark shortly. If you want to switch to the mobile phone while receiving hands-free and make a secret call, touch the phone mark slightly longer (about 2 seconds).

In addition, in the Bluetooth pairing operation (press and hold for about 3 seconds), during pairing, the LED of the Bluetooth mark and the LED of the hook mark periodically blink twice, and at this time, the type of LED stand ( For example, DL-60BSH of DIASONIC Corporation) is selected. When paired normally, the LED stops flashing and only the LED of the blue mark is turned on (Bluetooth mode). In the FM ON state, if the pairing is successfully connected, the FM is turned OFF and switches to Bluetooth mode. Also, if not connected for 2 minutes after pairing attempt, pairing is released and LED stops blinking. If it is already connected, pairing will not be executed and the hook LED will stop after three flashes (a signal that cannot be paired). To pair in the connected state, turn off Bluetooth on the external device (mobile phone).

In the ON / OFF operation of the Bluetooth mode, the LED is turned on when the Bluetooth mode is OFF (Bluetooth LED OFF-> Bluetooth LED ON). At this time, if FM mode is ON, turn OFF (FM LED ON-> FM LED OFF). If it is not connected, the hook LED blinks 3 times and stops (signal is not connected). Turn off when Bluetooth mode is ON. If music is being played from an external device (mobile phone), stop processing.

Next, when we talk about answering a call, the phone rings at the same time on the phone and LED stand, and the hook LED on the LED stand flashes. The user presses the hook button briefly to answer the call, and when the call ends, the user presses the hook button shortly to end the call. In FM mode, switch to Bluetooth mode after FM OFF. Incoming calls can be answered regardless of the Bluetooth mode. If music is being played on the mobile phone, the music is paused and automatically resumed after the call ends.

In the case of rejection, if the hook button is pressed for a long time (about 1.5 seconds) when the telephone rings, the reception is rejected.

In dialing, the hook LED turns on when a call is made from the mobile phone, but there is no dialing function on the stand.

When switching a call, only when you are in a call, press the hook mark for about 1.5 seconds to switch from the stand to the mobile phone or from the mobile phone to the stand.

Next, in the FM mode ON / OFF, it turns ON when the FM mode is OFF (FM LED OFF-> FM LED ON). At this time, if Bluetooth mode is ON, process OFF. In case of playback mode, process stop (Bluetooth LED ON-> Bluetooth LED OFF). Turn off if the FM mode is ON.

During frequency scan of the broadcast channel, pressing the "<" or ">" mark on the LED stand for a longer time (about 1 second or more) switches to the scan mode and the FM radio mark flashes. After the scan is complete, touch the "<" or ">" mark slightly shorter to move to the memorized frequency channel. At this time, during reception of the FM broadcast, the phone mark of the Bluetooth flashes when a call is made to the mobile phone, and when the call is received in hands-free mode, the radio is switched from the FM radio reception mode to the Bluetooth hands-free mode.

In addition, the LED stand 100 of the present invention, as a power output unit 111, for example, a built-in charging terminal of the mobile device, thereby, for example, provided with a charging terminal of the USB type A, such as a mobile device (eg, rated 5V / 1.5A) can be charged.

As described above, according to the present invention, by providing a multi-function LED stand with a variety of functions, such as Bluetooth function as well as FM radio listening function, by using the charging terminal of the power output unit provided in the LED stand for mobile devices such as mobile phones While charging, it is possible to listen to audio or use hands-free by using the Bluetooth function provided in the LED stand, and to listen to the FM radio provided in the LED stand.
