The lighting device is a circuit board accommodated in a box-shaped case and a circuit provided on the board. The lighting device can be connected to a commercial AC power source through an adapter, and can output a DC current from the AC power source. Therefore, the lighting device is electrically connected to the light source 160, outputs the DC current to the light source 160, and performs lighting control on the light source 160. The lighting device may be located or provided outside or inside the case 110 (for example, inside the storage chamber 112).

  As shown in FIG. 1, when the illumination device 100 illuminates, light emitted from the light source 160 enters the second transparent substrate 130 through the side light incident surface 133 and is transmitted inside the second transparent substrate 130. The light reflecting structure 150 of the fourth surface 132 destroys the transmission of the total reflection of the light beam, so that the light beam inside the second transparent substrate 130 is reflected outside the third surface 131 and further passes through the first transparent substrate 120. Then, it can be emitted outside the lighting device 100. Therefore, when the user uses the mirror surface (mirror surface region 122a) of the lighting device 100, the light source 160 is simultaneously opened to emit light, and the light emitted from the light transmitting region 122b is used as auxiliary illumination. Can have performance at the same time.

  FIG. 3 is a diagram illustrating an illumination device according to an embodiment of the present invention. In one embodiment, the second transparent substrate 130 may be omitted from the lighting device 100.

Therefore, in the present embodiment, when providing illumination, the light emitted from the light source 160 enters the first transparent substrate 120 and is transmitted inside the first transparent substrate 120. By destroying the transmission of the total reflection of the light beam by the light reflecting structure 250 of the light transmitting region 122b, the light beam inside the first transparent substrate 120 is reflected outside the first surface 121 and emitted outside the lighting device 100. be able to. Therefore, when the user uses the mirror surface (mirror surface region 122a) of the illumination device 100, the light source 160 is simultaneously opened to emit light, thereby providing auxiliary illumination using light rays emitted from the light transmitting region 122b, and the performance and illumination of the mirror.

In one embodiment, the case 310 exposes at least a portion of the fourth surface 132 of the second transparent substrate 130, and the light reflecting structure 350 simultaneously includes a partial region of the third surface 131 of the second transparent substrate 130 and the fourth surface. 132 can be formed in a partial region. For example, the light reflecting structure 350 of the third surface 131 is positioned to face the mirror surface region 122a, and the light reflecting structure 350 of the fourth surface 132 is positioned to face the light transmitting region 122b. The light source 160 is located on at least one side of the second transparent substrate 130, and emits a light beam inside the second transparent substrate 130. Therefore, when the light source 160 emits light, some of the light rays inside the second transparent substrate 130 pass through the first transparent substrate 120 due to the reflection of the light reflecting structure 350 on the fourth surface 132, and the other part. Is transmitted through the fourth surface 132 by the reflection of the light reflecting structure 350 on the third surface 131 and emitted to the outside, so that the effect of double-sided light emission can be achieved.
