請參閱「第1A圖」及「第1B圖」所示，為本發明第一實施例所揭露 之一種抗紫外線之冷光看板1〇〇，係以電能產生冷光，而呈現發光明亮的 文字或圖案，產生告示效果。冷光看板係可抵抗紫外線之破壞，不因承受 陽光直接照射而快速縮短使用壽命。因此冷光看板1〇〇可被設置於戶外環 境中，使其設置的地點不會受到限制。此外，由於冷光看板丨⑻可直接受 到陽光照射，因此可結合太陽能發電元件，以透過太陽能發電達成自供電。 請結合參照「第2A圖」及「第2B圖」所示，冷光看板1〇〇包含一框 架110、一冷光元件12〇、一隔熱膜13〇、一可透光之太陽能板14〇、及一 後背板150、及一充放電裝置16〇。 框架110用以作為支撐結構，以承載前述元件。框架11〇具有複數個 邊框ill ’各邊框ill係串連並環繞形成一中空區域112。通常邊框m的 7 1364731 數量為四，使框架111及中空區域112呈現矩型。 隔熱膜130係固定於冷光元件120的一側面，且冷光元件12〇之邊緣 係固定於邊框111之内側，使冷光元件12〇及隔熱膜13〇被固定於中空區 域112。一般而言，框架110具有二型態相同的框元件u〇a，互相重疊而 結合成為該框架110，且冷光元件120的邊緣係被夹持在二框元件1丨加之 間，而被固定於邊框112的内側。當然，冷光元件12〇也可以透過其他方 式邊框112之内側，例如以黏膠黏合、使用螺栓固定、使用鉚釘固定。框 架110之厚度係大於冷光元件12〇及隔熱膜13〇結合後之厚度，且冷光元 件120之邊緣係固定於邊框U1之内側面，因此冷光元件12〇及隔熱膜 之表面與框架110之二側面之間仍保有一間隔距離。 隔熱膜130可被直接黏合於冷光元件120上，也可以透過框架HQ的 .··〇 s，將隔熱膜110之邊緣固定於邊框111之内側，使隔熱膜間接地

配置型態，於通電而被電激發光後，在冷光元件120上呈現明亮的文字或 是圖案。或是將冷光材料平均地配置於封裝塑料，令冷光元件12〇成為可 均勻發光的板體，以發出光線穿透繪製圖案或文字的圖樣板。 8 1364731 一般而言，冷光元件12〇中，電激發光之冷光材料受到紫外線（波長 介於200〜400mn之間）照射之後，發光效能會加速衰退。而陽光尹的輻 射熱，例如紅外線，也會造成冷光材料溫度上升，加速冷光特性的衰退。 本發明中隔熱膜130係設置於冷光元件丨2〇之側面，用以隔離太陽光中紫 外線及輻射熱。在陽光照射的戶外環境中，可以降低投射至冷光元件12〇 之紫外線能量及輻射熱，延長冷光元件12〇在陽光充足的戶外環境中的使 用壽命，使冷光看板100適合被放置在會受陽光直射的室外環境下。

在太％能板140輸出極為微弱或是停止輸出時（代表周遭環境已經逐 漸進入夜晚）’充放電裝置160可進行放電釋放所儲存的電能，傳送至冷光 元件120而驅動冷光元件12〇進行發光。冷光元件12〇發出之冷光因波長 與隔熱膜110、太陽能板140所吸收的光譜不同，因此冷光仍可穿透隔熱 膜110、太陽能板140 ’呈現發光的文字或圖樣。 太陽能板140暴露於外部環境中，容易受到落塵等癖污物附著，薪污 物會阻隔陽光’影響太陽能板140的發電效率，此外這些辦污物也會阻隔 冷光元件120發出之光線，影響冷光看板之美觀度。太陽能板14〇之表面 塗佈一自潔塗層，使髒污物不易附著於太陽能板140表面，維持太陽能板 140表面的清潔。 參閱「第3圖」所示’如前所述’隔熱膜130係可隔絕紫外線UV及 輻射熱，。在設置冷光看板100時，冷光元件120黏貼在隔熱膜130的一 1364731 面係朝外或是朝向曰照面，以使太陽能板H〇受到最大曰照。穿透太陽能 板ΗΟ之紫外線UV及輻射熱可被隔熱膜130阻隔，使入射於冷光元件120 之紫外線UV及輻射熱的能量被減少至最低。而隔熱膜13〇所阻隔的光線 波長’係僅針對紫外光UV及高溫輻射熱，因此冷光元件120發出之冷光 CL仍可穿透隔熱膜13〇，呈現預定的亮光文字或圖案。 請參閱「第4Α圖」、「第4Β圖」、「第5八圖」、及「第5Β圖」所示，

[Prior Art] -· Self-illuminating advertising billboards, which are set in the advertising billboard, use light source to penetrate/semi-penetrate the kanban box or pattern board, so that the advertising pattern or text is bright to be in a dark place (such as Indoor or φ is nighttime) can still be clearly identified. Or directly design the light source into a specific pattern or text, which is directly illuminated in the dark %. The conventional light source includes a general bulb, a tooth lamp, a fluorescent lamp, a gas discharge lamp, etc., and such a light source must be driven by a large voltage and a large current, and is used for a long time, and the overall power consumption is large. And the continuous high heat generated during continuous glazing also shortens the actual life of the light source. In response to the above problem, a luminescent material having a low operating voltage, low power consumption, and low operating temperature is cited as a light source for an advertising billboard. The low operating temperature of the luminescent material allows the luminescent material to be easily packaged in plastic into any type of luminescent element that can be placed in a small installation space, thereby reducing the overall size of the advertising kanban. Low power consumption of cold light components, tens of long _ need lighting • · When advertising billboards, it can also greatly reduce the power consumption of advertising billboards. Light materials and level energy will also be shouted back and forth between the materials, but the use of the new button is still able to turn over. However, if the luminescent material is exposed to ultraviolet radiation or exposed to high temperatures, the rate at which the luminescent material decays is accelerated, which greatly shortens the life of the luminescent material. Sunlight is the environment + the main source of ultraviolet light, accompanied by high radiance. Therefore, if the luminescent material is used as an outdoor advertising billboard, the ultraviolet light in the sunlight will accelerate the decline of the luminescent material, and the sunshine will be further accelerated by the sunshine, and the luminescence performance of the luminescent material will be degraded, and the service life of the luminescent material will be greatly shortened. In summary, although the luminescent material has the advantages of low operating voltage, low power consumption, and easy shaping, it is not suitable for the glare, so that the cold light (4) is not suitable for outdoor use. . . . [Explanation] When the luminescent material is exposed to ultraviolet light, it will accelerate the rate of decline in luminescence performance, and will greatly shorten φ and short life. The present invention provides an anti-ultraviolet luminescent panel comprising a luminescent element, a thermal barrier film, a front panel, and a back panel. The luminescent element receives an electrical energy to emit luminescence. The thermal barrier is fixed to one side of the luminescent element to isolate the ultraviolet light. The front panel is light transmissive and disposed on the outer side of the thermal insulation film, and the rear back panel is disposed on the outer side of the cold light element, so that the cold light element and the heat insulating film are protected between the front panel and the back panel. The cold light emitted by the cold light element passes through the front panel to produce a bright light effect. The ultraviolet light from the sunlight passes through the front panel and is isolated by the heat insulation film. The cold light element is not directly irradiated by a large amount of ultraviolet light, thereby extending the cold light element. The service life under the sun. In addition, the 'insulation film can also isolate radiant heat, such as infrared rays, from direct sunlight to the luminescent element, causing the temperature of the luminescent element to rise and accelerating the degradation of the luminescent properties. Therefore, the anti-ultraviolet luminescence kanban of the present invention can be disposed in an outdoor sunny place without considering the problem that the illuminating performance of the luminescent element is degraded by ultraviolet rays or high temperature. The cold light illuminating board disclosed in the present invention can be disposed in a sunny outdoor area. In another embodiment of the present invention, a luminescent cold light illuminating board is provided, which is connected to a cold light element and a solar panel by a charging and discharging device. The solar panel receives sunlight to generate electric energy, and is stored in the charging and discharging device to supply electric energy from the charging and discharging device to cause the luminescent element to emit light. Therefore, the luminescent kanban can be self-powered by the sunlight of Tai 6 1364731, reducing the use of external power. Another embodiment of the present invention provides an anti-ultraviolet luminescent panel that replaces the front panel with a light-transmissive solar panel, and the solar panel and the luminescent component are electrically connected to a charging and discharging device to form a self-powered luminescent panel. system. The invention has the effect that the invention can effectively reduce the total energy of the ultraviolet light irradiated to the cold light element/cold light material in the sunlight, and delay the decline of the light emitting performance of the cold light element/cold light material. Therefore, the present invention can be installed outdoors, and fully utilizes the characteristics of low operating voltage, low power consumption, and long life of the luminescent material. Preferred embodiments of the present invention and their effects are described below in conjunction with the drawings. [Embodiment] Please refer to "1A" and "1B", which is a UV-resistant cold light illuminator according to a first embodiment of the present invention, which generates luminescence by electric energy and emits bright light. The text or pattern that produces the notice effect. The cold light kanban is resistant to UV damage and does not quickly shrink its life due to direct sunlight. Therefore, the cold light kanban can be placed in an outdoor environment so that the location of the kanban is not limited. In addition, since the cold light kanban (8) can be directly exposed to sunlight, it can be combined with solar power generation elements to achieve self-power supply through solar power generation. Please refer to "2A" and "2B" for reference. The luminescent slab 1 〇〇 includes a frame 110, a luminescent element 12 〇, a thermal insulation film 13 〇, a permeable solar panel 14 〇, And a back plate 150 and a charging and discharging device 16A. The frame 110 is used as a support structure to carry the aforementioned components. The frame 11 has a plurality of frames ill. Each of the frames ill is connected in series and surrounds a hollow region 112. Usually, the number of 13 1364731 of the frame m is four, so that the frame 111 and the hollow region 112 are rectangular. The heat insulating film 130 is fixed to one side of the luminescent element 120, and the edge of the luminescent element 12 is fixed to the inner side of the frame 111, so that the luminescent element 12 and the heat insulating film 13 are fixed to the hollow region 112. In general, the frame 110 has two frame elements u〇a of the same type, which are overlapped and joined to form the frame 110, and the edge of the luminescent element 120 is clamped between the two frame elements 1 and is fixed to The inside of the bezel 112. Of course, the luminescent element 12A can also pass through the inside of the other frame 112, for example, by adhesive bonding, bolting, and fixing with a rivet. The thickness of the frame 110 is greater than the thickness of the luminescent element 12 〇 and the thermal insulation film 13 〇, and the edge of the luminescent element 120 is fixed to the inner side of the frame U1, so the surface of the luminescent element 12 and the thermal insulation film and the frame 110 There is still a separation distance between the two sides. The heat-insulating film 130 can be directly bonded to the luminescent element 120, or the edge of the heat-insulating film 110 can be fixed to the inner side of the frame 111 through the frame HQ, so that the heat-insulating film is indirectly fixed by the frame 110. On the luminescent element 120. The heat insulating film 130 is used to insulate light of a specific wavelength range and reduce the energy of the light penetrating through the heat insulating film 13 . The cold light element 120 comprises a packaged plastic, a conductive line and a luminescent material. The packaged plastic is shaped into a plate shape and the luminescent material and the conductive line are coated inside, and the luminescent material and the power source are connected by a conductive line. The configuration pattern of the luminescent material determines the appearance of the luminescent element 12 after illuminating. The luminescent material can first form a configuration pattern representing a specific pattern or text in the packaged plastic, and is electrically excited when energized. After the light, a bright text or pattern is presented on the luminescent element 120. Alternatively, the luminescent material is evenly disposed on the package plastic, so that the luminescent element 12 is turned into a uniformly illuminable plate body to emit light to penetrate the pattern plate of the drawing pattern or the text. 8 1364731 In general, in the luminescent element 12〇, the luminescent material that is electrically excited is irradiated with ultraviolet light (with a wavelength between 200 and 400 mn), and the luminescence efficiency accelerates the decay. The radiation heat of Sunshine Yin, such as infrared rays, also causes the temperature of the luminescent material to rise and accelerate the degradation of the luminescence characteristics. In the present invention, the heat insulating film 130 is disposed on the side of the luminescent element ,2〇 to isolate the ultraviolet rays and radiant heat in the sunlight. In the outdoor environment exposed to sunlight, the ultraviolet energy and radiant heat projected to the luminescent element 12 can be reduced, and the service life of the luminescent element 12 in a sunny outdoor environment can be extended, so that the luminescent slab 100 can be placed in direct sunlight. Outdoor environment. The light-transmissive solar panel 140 is disposed on the front side of the frame no, and is located outside the heat-insulating film 13A. By the spacing of the frames 110, a hollow layer 110b' is formed between the solar panel 140 and the heat insulating film 13'. The hollow layer 11b is filled with air in a normal state. Therefore, it may also be referred to as an air layer. When sunlight is applied to the solar panel 140, part of the light directly penetrates the solar panel 140 and is incident on the thermal barrier film 130. Light of a specific wavelength is absorbed by the solar panel 14 and converted into electric energy. The back plate 150 is disposed on the side rear side of the frame 11〇 and is located on the outer side of the luminescent element 12〇. At the same time, by the barrier of the frame 110, a hollow layer 110b may also be formed between the back plate 150 and the luminescent element 120, which may also be referred to as an air layer. The back panel 150 and the solar panel 14 sandwich the frame 110 forward and backward, so that the heat shield film 130 and the luminescent element 120 are protected by the solar panel 14 and the back panel 150, respectively, without being damaged by an external force. The two hollow layers can insulate heat conduction, and prevent the solar panel 140 and the back panel 150 from being directly thermally conducted to the heat insulating film 13 and the luminescent element 120 after being exposed to sunlight, thereby further extending the service life of the luminescent element 120. The charge and discharge device 160 is provided with a charge and discharge function and a rectification function' electrically connected to the solar panel mo 9 1364731 and the cold light 70 member 120. When the umeng board 14G is exposed to sightseeing light to generate electric energy (four) the charging and discharging device 160 can be charged by the electric energy output by the solar panel M0. In addition, part of the energy of the sunlight spectrum towel that penetrates the solar panel (10) is also absorbed by the solar panel (10), reducing the energy of the ultraviolet light directly incident on the thermal insulation film 130, and finally after being separated by the thermal insulation film 13 The amount of material projected to the luminescent element 12G is reduced to a minimum, and the __ is also isolated to avoid cold light. The 7L SJ is heated for the sun. The luminescent panel of the present invention can be placed in the outer sunlight. Sufficiently' does not accelerate the decay of the luminescent element 12〇 due to the fineness and the shot. At the same time, 'sufficient sunlight exposure is also conducive to solar panels 14 to generate electricity from sunlight, reducing the need for external power, forming a self-powered system. When the output of the solar panel 140 is extremely weak or the output is stopped (representing that the surrounding environment has gradually entered the night), the charging and discharging device 160 can discharge and store the stored electrical energy, and transmit it to the cold light element 120 to drive the cold light element 12 to emit light. . The cold light emitted from the cold light element 12 is different from the spectrum absorbed by the heat insulating film 110 and the solar panel 140, so that the cold light can penetrate the heat insulating film 110 and the solar panel 140' to emit a light or pattern. The solar panel 140 is exposed to the external environment, and is easily attached by dirt such as dust, and the sewage will block the sunlight from affecting the power generation efficiency of the solar panel 140. In addition, these pollutants also block the light emitted by the cold light component 120, affecting the cold light. The beauty of the kanban. The surface of the solar panel 14 is coated with a self-cleaning coating so that dirt does not easily adhere to the surface of the solar panel 140, and the surface of the solar panel 140 is kept clean. Refer to the "Fig. 3" as shown in the above section. The heat-insulating film 130 is capable of isolating ultraviolet UV and radiant heat. When the luminescent glazing 100 is disposed, the luminescent element 120 is adhered to the surface of the insulating film 130 facing outward or toward the illuminating surface so that the solar panel H 〇 is subjected to the maximum illumination. The ultraviolet UV and radiant heat penetrating the solar panel can be blocked by the heat insulating film 130, so that the energy of ultraviolet rays UV and radiant heat incident on the luminescent element 120 is minimized. The light wavelength "blocked by the heat insulating film 13" is only for ultraviolet light UV and high temperature radiant heat, so the cold light CL emitted from the cold light element 120 can still penetrate the heat insulating film 13 〇 to present a predetermined bright text or pattern.
