Description of the Invention: [Technical Field] The present invention relates to a lighting device, and more particularly to an illumination device incorporating a plurality of light guide plates. [Prior Art] FIG. 1A is a A partial cross-sectional view of a conventional illumination device and FIG. 1B is a top plan view of the illumination device of FIG. 1A after removal of the front frame. Referring to FIG. 1A and FIG. 1B , the illuminating device 1 〇〇 includes a light guide plate 110 , a plurality of first light emitting diodes 120 , a plurality of second light emitting diodes 130 , a front frame 140 , and a light box 150 . . The light box 150 has a bottom plate 152 and a plurality of side plates 154 connected to the bottom plate 152. The light guide plate 110 has a first surface 112, a second surface 114 opposite to the first surface 112, and a light incident surface 116, 118' connecting the first surface U2 and the second surface 114. The light incident surface H6 is opposite to the light incident surface. 118. The light guide plate 110 is disposed on the bottom plate 152. The first light-emitting diodes 12A and the second light-emitting diodes 130 are respectively disposed in the light box 150 and are located on the opposite two side plates 154. The first light emitting diode 12 is adapted to emit light toward the light incident surface 116, and the second light emitting diode 130 is adapted to emit light toward the light incident surface 118. The light emitted by the first light-emitting diode 120 and the second light-emitting diode 13 进入 enters the light guide plate 11 from the light-incident surface 116 and the light-incident surface 118, respectively, and the inflammation is transmitted to the light guide plate UG via the first surface m. In addition, (10) a surface light source. The front frame has been placed on the light box 150 and covers the edges of the first light-emitting diode 12 〇, the second light-emitting diode 丨 3 〇 and the light guide plate 11 。. In order to enable the illuminating device 100 to be connected to the household power source to drive the PT1349 28474 twf.doc/n light emitting body 120 and the second light emitting diode i3 〇 to emit light, the outside of the light box I% needs to be externally connected with a driving circuit board and AC to DC power converter. However, the driving circuit board disposed outside the light box 15 and the AC to DC power converter may affect the appearance of the lighting device 100, and may cause the driving circuit board and the AC to DC power source to be accidentally caused to fall off during installation and use. The converter has been dropped and damaged. In addition, the conventional lighting device 100 employs a single piece of light guide plate 11A. When the user's demand is a large-area surface light source, the light guide plate 11 must be enlarged, causing the weight of the single-piece light guide plate 110 to be excessive, which causes the cost to rise and the weight of the illumination device 100 is too heavy to be handled. Furthermore, referring again to FIG. 1A, the first light emitting diode 120 and the second light emitting diode 130 are disposed on the side plate 154 of the light box 15A. When the first and second light-emitting diodes 120, 130 emit light, heat H is simultaneously generated. However, in the conventional illumination device, the heat generated by the LEDs 120, 130 is transmitted to the side plate 154, and when it is conducted upward, the top portion 154a of the side plate 154 is encountered and cannot continue to conduct, so the heat is generated. It can only be conducted downwards' to continue to conduct to the bottom plate 152 connected to the side plate 154, thereby being dissipated into the air. Since the heat H generated by the light-emitting diodes 120 and 130 is only transmitted downward, the heat dissipation efficiency of the light-emitting diodes 12〇 and 13〇 is poor, which in turn affects the light-emitting diodes 12〇 and 13〇. Luminous efficiency and service life.
