Please refer to the second A diagram, which is a side view of the creative illumination assembly. The light-emitting component 20 includes a light guide plate 21, a pattern layer 22, and a light source 23. The light guide plate 21 has a front surface 211 and a back surface 212, and the front surface 211 corresponds to the back surface 212. The pattern layer 22 is disposed on the back surface 212, and the light source 23 is disposed adjacent to the light guide plate 21.

When the light source 23 emits light, the light guide plate 21 can mostly emit light from the light source 23 from the front surface 211, so that when the light guide plate 21 is viewed from the front side 211, the first view angle 25 as shown in FIG. Not only can the pattern of the pattern layer 22 be clearly seen, but the light guide plate 21 serves as a shielding plate; in addition, when the light guide plate 21 is viewed from the front side of the back surface 212, the second angle of view 26 as shown in FIG. The light guide plate 21 serves as a see-through plate. In the present embodiment, the ratio of the amount of light from the front surface 211 to the amount of light emitted from the back surface 212 is preferably between 1.2 and 19.

Since the pattern layer 22 under the light guide plate 21 can refract, reflect, and the like from the light source 23, most of the light is emitted from the front surface 211, and therefore, when the light guide plate 21 is viewed from the front side of the front surface 211, it can be clearly The pattern of the pattern layer 22 is seen. At the same time, the shielding and see-through effects are respectively formed from the front side of the front surface 211 and the back surface 212. The reason is that first, since most of the light is emitted from the front surface 211, when the light guide plate 21 is viewed from the front side of the front surface 211, the light glare is more obvious. The effect is that it is difficult for the human eye to clearly see through the light guide plate 21, and a substantial shielding effect is produced; on the contrary, since a small amount of light is emitted from the back surface 212, therefore, when the light guide plate 21 is viewed from the front side of the back surface 212, there is no light glare effect. The human eye can clearly see through the light guide plate 21 to produce a substantial perspective effect. And/or second: since most of the light is emitted from the front surface 211, and part of the foregoing light is reflected or refracted from the background or object (not shown) in front of the front surface 211 and penetrates to the back surface 212 of the light guide plate 21. Therefore, when viewing the light guide plate 21 from the front side of the back surface 212, it is easy to see the background or object (not shown) in front of the front surface 211, and a substantial perspective effect is produced; on the contrary, since a small amount of light is emitted from the back surface 212, And a part of the foregoing light rays are reflected or refracted from the background or object (not shown) in front of the back surface 212 and penetrated to the front surface 211 of the light guide plate 21, and thus, when the light guide plate 21 is viewed from the front side of the front surface 211 It is not easy to see the background or object (not shown) in front of the back surface 212, and a substantial shadowing effect is produced.

As shown in FIG. 2A, the light guide plate 21 further includes a side 213, and the side 213 is interposed between the front surface 211 and the back surface 212. In this embodiment, the two sides of the side 213 are adjacent to the front side at the same time. 211 and back 212. The light guide plate 21 is made of a light transmissive material, and the material thereof may be polymethyl acrylate (commonly known as Polymethyl Methacrylate, PMMA), polycarbonate (Polycarbonate, PC), or cyclic olefin polymer (Cyclic Olefin Copolymer, COC). ), polystyrene (PS) or glass (Glass).

Moreover, in the present embodiment, the illumination source 23 faces the side 213, and the light emitted from the illumination source 23 can be transmitted through the side 213 into the light guide plate 21. The light source 23 can be a single or a plurality of Light Emitting Diodes (LEDs), a Cold Cathode Fluorescent Lamp (CCFL), or the like.

The pattern layer 22 will be further explained. The pattern layer 22 has a plurality of microstructures 221 protruding from the back surface 212. Preferably, the microstructures 221 are printed structures. The printing structure is formed directly by printing ink or colloid, or after printing ink or colloid first, and then indirectly by using light (such as UV, IR, etc.), heating, cooling, solid pressing, etc., but not Limits, those who directly or indirectly form microstructures by printing liquids are within the scope of the printing structure described in this creation.

Thereby, when the microstructure 221 is formed on the surface 241 of the interface layer 24, the microstructure 221 is arched due to the small surface tension of the surface 241 of the interface layer 24. The material of the interface layer 24 may be an acrylic material (such as methyl methacrylate and surface modifier), but not limited thereto, and the material of the interface layer has low surface tension characteristics. It belongs to the interface layer described in this creation.
