It saves electricity, is environmentally friendly, has no consumables, reduces the consumption of natural resources, and emits carbon dioxide. It can truly achieve green lighting. The above described features and advantages of the present invention will become more apparent from the description of the appended claims. [Invention] This embodiment will introduce a light collecting device with a light guide plate, which can introduce sunlight or other natural light into the room as an indoor illumination source or as another available light source without using a large lens or a solar battery. The power required to convert into lighting 'is easy to install on the wall or roof of the building (home), as long as the natural light is sufficient, the light can be collected and transmitted to the interior of the building (home) where it needs to be illuminated. The components of the light guide plate, the reflective film, the first light collecting structure, the second light collecting structure, the collecting and transporting components of the light collecting device will be described in detail below, but the present invention is not limited to the following two embodiments. 1A and 1B are schematic views respectively showing a light guide plate of a light collecting device according to an embodiment of the present invention. Referring to FIG. 1A and FIG. 1B, the light guide plate 1A has a light incident surface 102, a reflective surface 104, and a light exit surface 1〇6. The light incident surface 102 intersects the reflective surface 104 to form a first inner angle θ y of the light guide plate 1 且 and the light exit surface 106 intersects the reflective surface 1 〇 4 to form a light guide plate 1 第二 - a second inner corner Θ 2, wherein An inner angle θι is smaller than the second inner angle Θ2. For example, the light guide plate 100 is a light transmissive material, and the material thereof includes glass or plastic. The light guide plate 100 is, for example, a long and narrow wedge plate, and the angle of the apex angle of the wedge plate 201104286 ^54y»uui3TW 30984twf.doc/n (ie, the first inner angle 0 1) is between 1 and 30 degrees, preferably Between 1 and 5 degrees. Since the light guide plate 100 is a light transmissive material, the light L of the light source (natural light or light source module) is incident into the light guide plate 1 at an incident angle, and is reflected by the reflection surface 104 to finally reach the light exit surface 1〇6. The reflective film 11 is, for example, a totally reflective film (as shown in Fig. 1A) or a film having total reflection and partial reflection characteristics (Fig. 1B) covering the reflecting surface 1〇4. The material of the reflective film 110 is, for example, an organic material or an inorganic material, and may be formed by a process such as attaching, coating or physical/chemical deposition. In this embodiment, the reflective film 110 is used to increase the light utilization efficiency, but the thickness and refractive index of the reflective film 110 can be adjusted according to different conditions, and the invention is not limited. Further, according to the law of total reflection, when the light L enters from the medium of higher refractive index to the medium of lower refractive index 'and the incident angle is larger than the critical angle, it is called total reflection because no refraction occurs. It can be seen that when the light L in the light guide plate 1 is in accordance with the law of total reflection, the light L will reach the light exit surface 106 directly or indirectly from the reflective surface 104 and the reflective film 11 by at least one primary reflection. The light-emitting surface 106 is emitted to achieve the effect of collecting light. In addition, FIG. 1C illustrates a reflective film H〇 of another embodiment disposed adjacent to the reflective surface 104, and the reflective surface 丨〇4 and the reflective film u〇 are separated. With a proper spacing, the efficiency of light utilization can also be increased by the reflective film 11〇. Therefore, the arrangement of the reflective film 11A is not limited to the above two embodiments. It is to be noted that, in order to achieve the effect of collecting a large amount of light, the area of the light incident surface 102 of the light guide plate 100 and the surface of the reflective surface 104 are enlarged as much as possible, and the light emitting surface 106 is enlarged. The area of the light-incident surface 1 〇 2 is as small as possible. The total amount of light that is incident on the light guide plate 丨 (8) can be increased as the area of the light-incident surface 102 increases, and is emitted to the light guide plate 1〇. The luminous intensity (luminous flux per unit area) outside the crucible also increases as the area of the light-emitting surface 1〇6 decreases. In addition, the light-incident surface 1〇2 of the light guide plate 1〇〇 may be configured or formed according to the degree of light collection or the first light-collecting structure and/or the second light-harvesting structure 'to enhance the light collection efficiency'--the second set The light structure may be a polygonal mirror structure or a concentrating lens (for example, a Fresnel lens). In the following two embodiments, a light guide plate having a Wei structure is taken as an example, and the simplification of the present invention is carried out in conjunction with the drawings. However, the present invention is not limited to the following two embodiments. 2A and 2B are respectively a schematic view and a partial enlarged view of a light collecting device according to an embodiment of the present invention. Referring to FIG. 2A, the first light collection device 12〇1 has been placed on the light incident surface 102 of the light guide plate 100, and includes a plurality of prism units 122, for example, a plurality of triangular prisms arranged in parallel and connected. Mirror body. Each of the first mirror units 122 has a first top (four) and a first bottom _1 relative to the first top h, and each of the first apex angles has a first height H1 with a mesh distance from the first bottom surface D1 (eg 2 to 4 mm). Next, please refer to FIG. 2B , in addition to configuring the first light collecting structure 12 〇 to increase the light collecting effect, the second light collecting structure 13 can be disposed between the first light collecting structure 12 〇 and the light guiding plate 100 , and second The light collecting structure 130 includes a plurality of second prism units 132' such as a plurality of triangular prism shaped prism bodies arranged in parallel and connected. The second prism units respectively have a second apex angle cold and a second bottom surface D2 relative to the second apex angle /3, and each of the second apex angles has a 咼1 degree H2 apart from the second bottom surface D2 (eg 1 to 2 mm). The second height η〗 201104286 ro^fy〇uLfi3TW 30984twf.doc/a is often smaller than the first height HI. In detail, when combining and fixing the younger brother's first-level optical structures 12〇, 130, the orientations arranged or aligned in the following manners may be selected. The first vertex angle a of the first prism unit 122 and the second vertex angle ^ of the second prism unit 132 are opposite to each other, and the angle of the first vertex angle a is generally smaller than the angle of the second vertex angle, but the present invention does not This is limited to this. For example, if the angle of the first vertex angle a is an acute angle 'usually between 20 degrees and 80 degrees, a preferred angle is between 3 degrees and 40 degrees, and the angle of the second angle is /5. It is an obtuse angle and is usually between 95 and 105. In the above two embodiments, the light L of the light source may be refracted through the first light collecting structure 120 (the multi-mirror structure or the collecting lens) to be incident into the light guiding plate 100, and reflected by the reflecting surface 104 directly or indirectly. The ground reaches the light surface 106. In addition, the light L of the light source may also be refracted multiple times through the first/second light collecting structures 120, 130 (the multiplex mirror structure or the collecting lens) to be incident into the light guide plate 100 and directly reflected by the reflecting surface 104. Or indirectly to the light exit surface 106. In any case, the light that is finally emitted by the light exit surface 1〇6 can be collected to become available illumination. The following embodiment will introduce the light collected by the light guide and collected by the collector and transmitted to the desired illumination by the transmission component. 'to provide the required lighting. Furthermore, FIG. 2C shows the first/second light collecting structure 120, 130 of another embodiment, which sets the first vertex angle of the first prism unit 122 and the second vertex angle of the second prism unit 132. The β is staggered with each other, that is, the first vertex angle a and the second vertex angle do not need to be oppositely arranged. Therefore, the apex angle configuration is not limited by the above two embodiments. 11 201104286 i W 30984twf.doc/n FIG. 3 is a block diagram of a lighting apparatus according to an embodiment of the present invention. Referring to Figure 3, the lighting device includes a light collecting device 2, a collector 21, a transport assembly 220, and a light transmissive body 230. The collector 21 collects the light emitted by the light guide plate of the light collecting device 200, and the collected light is transmitted through the & The collector is, for example, a light consuming device' that is connected to one end of the transmission assembly 220, and the transmission assembly 220 is, for example, a fiber optic line that allows light to travel along the path of the pipeline. The light transmissive body 230 is located at the other end of the transport unit 22, for example, a wedge-shaped light guide plate, and has a structure such as a light incident surface, a reflective surface, and a light exit surface, but the light transmissive body 23G is a reverse use of the light collecting principle of the upper material light panel. Mainly to restore the light transmitted by the fiber line to the self-winding for illumination. Therefore, the area of the light-emitting surface of the light-transmitting body 23〇 should be as close as possible, and the area of the surface should be opposite to the light-collecting effect of the above-mentioned light guide plate, so that illumination with uniform illumination can be obtained. The above-mentioned light transmitting body 23〇 may be replaced by another light transmitting device, and the present invention is not limited thereto. 3 In summary, since the light collecting device and the lighting device of the present invention can use sunlight or other natural light guiding room as a room (four) light source or as other available light source, there is no need to use electricity and lamps, and power saving , environmental protection, no consumables, reducing the consumption of natural resources and carbon dioxide emissions, etc. can truly achieve green lighting. As long as the natural light is charged, the $β sets the light and transmits the light to the interior of the building (home) where it needs to be illuminated' both practical and groundbreaking. Although the present invention has been disclosed in the above embodiments, it is not intended to limit the knowledge of those skilled in the art, and it is possible to make some changes and refinements without departing from the spirit and scope of x, so this 12 201104286 Rjny〇uwi3TW 30984twf.doc/n The scope of protection of the invention is subject to the definition of the scope of the patent application.
