When the light source 1〇2 is turned on, the illumination light 1〇6 enters the inside of the light guide plate 4 from the at least one side 50 and respectively When the planar region 丨〇8 and the surface region 110 are penetrated to the outside of the light guide plate 〇4, the planar region 108 of the light guide plate 1〇4 and the surface region 110 are caused to generate double-sided illumination, wherein the surface region 11 The 〇 refracts a portion of the illumination. 5 M440392 The ray 106 passes out to the outside of the planar area 1〇8, and the surface area 11 〇 refracts another portion of the illuminating light 106 to exit to the outside of the surface area u〇. The surface region 110 is provided with a plurality of structural regions 112, each of the structural regions 112 having a plurality of microstructures 114. The microstructures 114 are, for example, concave regions. When the light source 1〇2 is turned on, a portion of the microstructures 114 are buckled. The illuminating light 1 〇 6 passes out to the outside of the planar area 1 〇 8 , and the microstructures 114 refract the other part of the illuminating light 1 〇 6 to pass out to the outside of the surface area 110 . In the embodiment, the structural regions 112 are a plurality of concave regions. The structural regions 112 are distributed in a fine or unrestricted manner to the torn surface area 110 of the light guide plate. The microstructures 114 are distributed in each of the structural regions 112 in an irregular shape or a regular shape. In one embodiment, the light source 102 is one of a light emitting diode (LED) or a xenon lamp. In one embodiment, the material of the light guide plate ι 4 is selected from the group consisting of poly(polyacrylic acid), g, polycarbonate, and glass, that is, the material of the light guide plate 104 is, for example, Transparent material. The first ic diagram is a perspective view showing a non-transparent state in which the luminaire 1 having transparency in the first embodiment is in an open state. The luminaire having transparency is just hanged on the ceiling 12 by means of a sling (10). The yoke (10) is in a state of uniform illumination on both sides. According to the above description, the luminaire having transparency is a microstructure 114 directly on the transparent light guide plate. When the light source 102 is not lit, the viewer 1 〇 9 is in a transparent state when the light guide plate 1 〇 4 is viewed from the outside. The arrow indicates the position; when the light source is lighted, the light-emitting lamp is illuminated at the same time, and the effect of the paste is achieved, and the viewer (10) is given the light guide plate 1 (the state is not transparent). For example, referring to the first diagram, the second diagram, and the second diagram, the second diagram is a schematic diagram showing various states of the screen 200 when the light source is turned on and off in the second embodiment of the present invention. Figure 2 is a perspective view showing a non-transparent state in which the screen (10) of the B_(10) is in a lining state in the second embodiment of the present invention. The screen having the transparency luminaire 100 of the present invention includes a light source and a light guide plate 〇4. The screen image is, for example, disposed on the table m, the light source is used to generate - illuminate the light. The light guide plate collapses - the plane region trace is located on the opposite side of the plane region (10) - the surface region 110, and the ship is located in the plane region At least one side between the surface regions n◦. 105 The light source 102 is not placed on the at least one side 1〇5, and when the light source is moved to be closed and the illumination light K)6 is not generated, from the planar area 1 The light guide plate 〇4 is in a transparent state, and the light guide plate 1〇4 is in the transparent state viewed from the outside of the surface region 110, and the light source 1〇2 is turned on to make the far-illuminated light 1〇. 6 from the at least one side 5〇 into the inner sub-section of the light guide plate and respectively penetrate the planar area view and the surface area 110 to the outer 4 of the light guide plate to make the planar area 108 of the light guide plate 104 and The surface area produces double-sided illumination, wherein the surface area 110 refracts a portion of the illumination ray 106 to exit to the exterior of the planar area 108, and the surface area 11 refracts another portion of the illumination ray (10) to exit the surface area 110. Externally, the surface luminance of the light illuminating light 〇6 through a portion passing through the planar region (10) is greater than the surface luminance of the other portion of the illuminating light passing through the surface region ηί) to view the light guide plate from the outside of the planar region 108 1〇4 series It is in an opaque state, and the light guide plate 104 is in a translucent state as viewed from the outside of the surface region 110. The surface region 110 is provided with a plurality of structural regions 112, each of the structural regions 112 having a plurality of microstructures 114. When the light source 1〇2 is turned on, the light is radiated by the microstructures 114. The exterior of the planar region 108, and the microstructures 114 refracting another portion of the illumination ray 106 exits to the exterior of the surface region 11A. In the embodiment, the structural regions 112 are a plurality of concave regions. The structural regions 112 are distributed in the surface area ι10 of the light guide plate 104 in an irregular shape or a regular shape. The microstructures 114 are in an irregular shape or a distributed distribution ride-structure region 112 t. In the embodiment, the light source 102 is one of a light emitting diode (LED) or a light tube. In one embodiment, the 'the light quality of the light guide plate 104 is selected from the group consisting of polyacrylic acid sulfonate (Cool 7), the polycarbonate (PC), and the glass, that is, the material of the light guide plate is torn. For example, it is a transparent material. As shown in Fig. 1A, when the light source 1〇2 is turned off so that the irradiation light 1〇6 is not generated, the light guide plate (10) is in a microscopic state. (10) The present optical optical board (10) is in a transparent state by the light guide plate 1〇4, so that the viewer 109 can see the scene on the side of the plane area from the side of the surface area 11〇, and can also make the viewer 109 a flat area. The side of 108 sees the scene on the side of the surface area u〇. Specifically, 'as shown in FIG. 1B', in order to achieve the above-mentioned front and back surfaces (that is, the plane area should be and the surface area _ _ the difference in brightness of the ship, the original optical screen secret (10) utilizes the structural area 112 and the structure area 112 The microstructure 114 changes the angle of refraction of the illumination wire 106 introduced into the light guide plate 1〇4 to control the brightness of the planar area 1〇8 and the sides of the surface area 11〇. When the light source 1〇2 is turned on, When most of the illumination rays 1〇6 the peripheral structure region 112 and the microstructure 1H are penetrated by the planar region (10), the high luminance m (the direction of the head is dense) is opaque (opaqUe) state by the light guide plate 104. So that the viewer 1〇9 can not see the scene on the side of the surface area 110 from the side of the plane area 108, so that the optical screen partition 1 〇〇 achieves the effect of shielding. For example, the front of the reflection is marked; at this time, a small part of the illumination The light 1〇6 is penetrated by the surface area 11〇M440392, which is a low luminance 113 (the direction of the arrow is thinner), and the translucent state is exhibited by the light guide plate 104, so that the viewer 109 can be flanked by the surface area 11 Seeing the planar area 108 in one direction The side item 'for example, an arrow indicates i〇9b. · In Fig. 2A, the light source is in a closed state, and the plane area 1〇8 of the light guide plate 1〇4 is in a transparent (four) jiajia state; in other words, by the first On the side of the plane area of Fig. 2A, the portrait 116 and the scene 117 on the side of the surface area 11 are visible. In Fig. 2B, the light source is in an on state, and the planar region 108 of the light guide plate ι 4 is high in luminance, so that the planar region 1 〇 8 is in an opaque (-) state. In other words, from the outside of the plane area of Fig. 2B, the external image 116 of the surface area is not visible, and only the exposed object ι 7 can be seen, but the planar area 108 can be seen from the outside of the surface area no. The external portrait 116 and the exposed item 117 are hidden. The difference in luminance between the touch region 11() and the planar region is mainly due to the structural region (4) of the surface region no and the change of the refractive limb generated by the microstructure 114, thereby adjusting the passing through the surface region 110 and the planar region 1〇8. Brightness. Fig. 3 is a perspective view showing the micro-state of the micro-state of the screen 200 having the transparency lamp 100 in the second embodiment of the present invention.
