The lateral light-emitting module 3 includes a board %, a light guide plate 33, and a 卞 31, and a metal substrate circuit I photo-polar body 34. Therefore, the metal base 11 200846776 circuit board 32, the light guide plate 33, and the light emitting diode 34 have the same technical features as the metal base material circuit board 22, the light guide plate 23, and the light emitting diode 24 in the first embodiment. And efficacy, no longer repeat here. The difference from the first embodiment is that in the embodiment, the lateral type and the light-emitting module 3 further comprise a frame 37 which is combined with the heat-conducting frame 31. The middle frame 37 supports the light guide plate 33. And the reflective sheet 35, and the material of the frame 37 can be metal, alloy or plastic. It should be noted that the heat conducting frame 31 is a heat conducting side frame and is disposed on one side of the frame 37, and the cross section of the heat conducting frame 31 is L-opening. The light emitting diodes 34 are disposed on the heat conducting frame 31, and the heat generated by the light emitting diodes 34 can be transferred to the heat rack 31 by the metal substrate circuit board 32, and then transferred to the frame body 37 by the heat conducting frame 31 to assist in heat dissipation. . Of course, the shape of the heat conducting frame 31 can be designed according to actual product requirements, and will not be described herein. Finally, please refer to FIG. 8 and FIG. 9 simultaneously to explain the lateral type light-emitting module according to the third embodiment of the present invention, wherein FIG. 9 is a partial cross-sectional view of the line c_c in FIG. The difference from the second embodiment is that, in this embodiment, the frame 37 of the lateral type illumination module 3' is a lower cover, that is, the frame 37, having a bottom 371, and the frame 37 The corresponding joint with the heat conducting frame 31 is a broken hole pl, and the plurality of carrying portions 372 are spaced apart in the broken holes to carry the heat conducting frame 31. Therefore, the frame 37 can be more tightly coupled to the heat transfer frame 31. In summary, according to a lateral type light-emitting module according to the present invention, the surface of the light-emitting diode system is adhered to the metal substrate circuit board. Compared with the conventional technology, since the surface of the light-emitting diode system is adhered to the metal substrate circuit cup double, and the gold 12 200846776 helps heat dissipation, the heat conduction effect of the substrate circuit board is better, so the light-emitting diode can have better performance. The heat dissipation efficiency further enhances the product quality of the light-emitting module. Furthermore, the metal substrate circuit board is lying flat in the lateral light-emitting module, so that compared with the prior art, the thickness of the horizontal and lateral light-emitting modules can be effectively increased, and the surface of the two circuit boards can be increased. area. In addition, the light-emitting body is transferred to the heat-conducting frame via the metal substrate circuit board to further cope with the invention.
