| 摘要 |
In the present invention, a control device module (4) having a mounting portion (14) is electrically connected to and small enough to be inserted into a general fluorescent lamp socket (36); a power pack (6) converting a commercial alternating current (AC) input voltage into a direct current (DC) output voltage is embedded in the mounting part (14) of the control device module (4); and a separation-type light emitting diode (LED) lighting unit (8) fits in a rear insertion portion (32) of the control device module (4). The separation-type LED lighting unit (8) includes a board (18) on which a plurality of LEDs (34) are arranged; a heat dissipation plate (22) installed on a rear surface of the board (18); an LED driving unit (16) fastened to the insertion portion (32) of the control device module (4) and coupled to the board (18); and a lighting cover (26) assembled to a front side of the LEDs (34) of the board (18). By inserting the control device module (4) including the power pack (6) for controlling the LEDs (34) into the fluorescent lamp socket (36) and fastening the LED lighting unit (8) to a rear end of the control device module (4), a working time of the LED lighting device (2) can be shortened, and replacement costs can be reduced. |
