Description

LED螢光照明裝置 LED fluorescent lighting device
本發明係有關於一種LED螢光照明裝置,其由透光性材料所構成,利用經過凹凸加工之導光擴散體以及經小型化至尺寸略等同於導光擴散體的散熱器而獲得廣範圍之配光角。 The present invention relates to an LED fluorescent lighting device comprising a light-transmitting material, which is obtained by a light-conducting diffuser subjected to concave-convex processing and a heat sink which is miniaturized to a size slightly equivalent to a light-conducting diffuser. The light distribution angle.
LED光源螢光燈因具有省能源,減少二氧化碳,未使用水銀等優點之特性,故取代習知之螢光燈之照明裝置成為注目焦點。然而,LED的光線為直線性且也沒有來自類似習知之螢光燈的燈具或天花板之反射,故LED螢光照明裝置的正下方被照射很明亮,但因為會產生光線照不到之處且非間接光線而係直線光,故會有目眩的問題產生。 Since the LED light source fluorescent lamp has the advantages of being energy-saving, reducing carbon dioxide, and not using mercury, the lighting device that replaces the conventional fluorescent lamp has become a focus of attention. However, the light of the LED is linear and there is no reflection from a lamp or ceiling like a conventional fluorescent lamp, so the LED fluorescent illumination device is illuminated very brightly underneath, but because the light is not illuminated and Non-indirect light is a straight line of light, so there is a problem of dazzling.
已知專利文獻1所揭示之技術內容乃解決此問題點。專利文獻1所揭示之技術內容係於LED光源螢光燈內將2片之LED光源基板102配置成背對背,利用於外部設置電源而加寬照射角度。(參考專利文獻1) The technical content disclosed in Patent Document 1 is known to solve this problem. The technical content disclosed in Patent Document 1 is that two LED light source substrates 102 are arranged back to back in an LED light source fluorescent lamp, and the irradiation angle is widened by externally providing a power source. (Refer to Patent Document 1)
在習知之LED螢光照明裝置101上,必須要2片LED光源基板102且需要配合於此之光源數目,故耗電為其缺點。另外,來自配置成背對背之2片LED光源基板 102的光線,由於各僅照射前方,故未照射到地方會出現黑線條,會帶給使用者不協調問題。 In the conventional LED fluorescent lighting device 101, two LED light source substrates 102 are required and the number of light sources to be fitted thereto is required, so power consumption is a disadvantage. In addition, from the two LED light source substrates configured to be back to back The light of 102, because each of them only illuminates the front, there will be black lines when it is not irradiated, which will bring the user an uncoordinated problem.
於是,提案出各種能夠以較少的光源數目來 加寬照射範圍之LED螢光照明裝置。譬如,專利文獻2之LED螢光照明裝置201,其管體200內部藉由內璧203分為二部分,即,一部分係由透光性合成樹脂等所構成,同時也係LED發光照明室之第1管體部204,另一部分係由金屬所構成之橫向剖面視為圓弧狀,同時也係電源室B之第2管體部205。於該管體202內部,其中具有水平面及一對傾斜面之內璧203,將該水平面自該管體202之中心往靠近第2管體部205側配置,且於該內璧203之水平面上之上面裝設有LED發光裝置206及螢光體207,於水平面下面裝設有電源電路208且於傾斜面安裝有導光擴散體209。 So, various proposals can be made with fewer numbers of light sources. LED fluorescent lighting device that widens the illumination range. For example, in the LED fluorescent lighting device 201 of Patent Document 2, the inside of the tube body 200 is divided into two parts by the inner tube 203, that is, a part is composed of a translucent synthetic resin or the like, and is also an LED lighting room. The first pipe body portion 204 is formed of a metal and has a lateral cross section which is regarded as an arc shape, and is also a second pipe body portion 205 of the power supply chamber B. The inside of the tubular body 202 has a horizontal plane 203 and a pair of inclined surfaces. The horizontal plane is disposed from the center of the tubular body 202 toward the second tubular body portion 205, and is disposed on the horizontal surface of the inner bore 203. The LED light-emitting device 206 and the phosphor 207 are mounted on the upper surface thereof, and the power supply circuit 208 is mounted on the lower surface of the horizontal surface, and the light-conducting diffuser 209 is attached to the inclined surface.
若藉由此LED螢光照明裝置201,即可使具有 水平面及一對傾斜面之內璧203,將該水平面兩端連接在金屬製之第2管體部205端緣,且使得內璧203及金屬製之第2管體部205可熱傳導地連接,於內璧203之水平面上面裝設有LED發光裝置206及螢光體207,且於水平面下面裝設有電源電路208,於傾斜面裝設有導光擴散體209,從內璧203大約全面於LED發光照明室A即第1管體部204內漫反射螢光光線,藉此可使照射範圍亦擴大至安裝面側。 By using the LED fluorescent lighting device 201, The horizontal plane and the inner side 203 of the pair of inclined surfaces are connected to the end of the second tubular body portion 205 made of metal, and the inner tube 203 and the second tubular body portion 205 made of metal are thermally conductively connected. An LED illuminating device 206 and a phosphor 207 are disposed on the horizontal surface of the inner cymbal 203, and a power supply circuit 208 is disposed below the horizontal plane, and a light guiding diffuser 209 is disposed on the inclined surface. The LED light-emitting illumination room A, that is, the first tube body portion 204 diffuses the fluorescent light, thereby expanding the irradiation range to the mounting surface side.

然而,於習知之LED螢光照明裝置201上,必須將從LED光源發出之光線朝第1管體部204發射,於導光擴散體209再次反射來自第1管體部204之反射光線,為了再次反射該反射光線,則必須於內璧203之傾斜面使用鋁箔來連接由三層構造所構成之導光擴散體209,如此一來會產生製造過程複雜且成本變高之問題。 However, in the conventional LED fluorescent lighting device 201, it is necessary to emit light emitted from the LED light source toward the first tube body portion 204, and the light guiding diffuser 209 reflects the reflected light from the first tube portion 204 again. When the reflected light is reflected again, it is necessary to use an aluminum foil to connect the light-conducting diffuser 209 composed of a three-layer structure on the inclined surface of the inner crucible 203, which causes a problem of complicated manufacturing process and high cost.
另外,藉由內璧203來遮擋LED發光照明室A即第1管體部204與裝設有電源電路208之電源室B的第2管體部205,會產生照射不到地方會超過90度範圍之問題存在。 In addition, the inner tube 203 blocks the first tube body portion 204 of the LED light-emitting illumination chamber A and the power source chamber B in which the power supply circuit 208 is mounted, and the illumination may not exceed 90 degrees. The problem of scope exists.
於是,本發明欲解決之課題,係提供一LED螢光照明裝置,可簡化製造步驟且可降低成本,不但可使配光角擴大至安裝器具側(屋頂面、璧面等),同時接近自然光並不刺激眼睛。 Therefore, in order to solve the problem of the present invention, an LED fluorescent lighting device is provided, which simplifies the manufacturing steps and reduces the cost, and can not only extend the light distribution angle to the side of the mounting device (the roof surface, the kneading surface, etc.), but also close to the natural light.

[實施發明之形態] [Formation of the Invention]
以下請參考圖面而詳細說明適用本發明之具體實施型態。本發明係適用於譬如第1、2圖及第11圖所示之構造的LED螢光照明裝置1。 Hereinafter, specific embodiments to which the present invention is applied will be described in detail with reference to the drawings. The present invention is applicable to an LED fluorescent lighting device 1 having a configuration as shown in Figs. 1, 2, and 11.
首先,茲參考第1、2圖及第5圖且說明LED螢光照明裝置1之概略構造。此LED螢光照明裝置1如第1圖所示,其主要具備有:可用來將於基板4產生之熱散熱之散熱器6;設置成使背面與散熱器6密合且支撐有LED光源部3之基板4;設置成與基板4之表面密合之LED光源部3;保持有LED光源部3及基板4及散熱器6,於內部讓來自LED光源部3之光線擴散且朝向外部照射之導光擴散體5;設置成挾持散熱器6且收容有設置LED光源部3及基板4之導光擴散體5與散熱器6的管體2;設置於管體2兩端之一對端蓋16a、16b;以及具備於端蓋16a、16b之支撐端子部17a、17b。 First, the schematic configuration of the LED fluorescent lighting device 1 will be described with reference to Figs. 1, 2 and 5. As shown in FIG. 1 , the LED fluorescent lighting device 1 mainly includes a heat sink 6 that can be used to dissipate heat generated by the substrate 4, and is disposed such that the back surface is in close contact with the heat sink 6 and supports the LED light source unit. The substrate 4 of 3; the LED light source unit 3 which is provided in close contact with the surface of the substrate 4; the LED light source unit 3, the substrate 4, and the heat sink 6 are held, and the light from the LED light source unit 3 is diffused inside and irradiated to the outside. a light guide diffuser 5; a tube body 2 provided with the heat sink 6 and housed with the LED light source unit 3 and the light guide diffuser 5 of the substrate 4 and the heat sink 6; and one end cover provided at both ends of the tube body 2 16a, 16b; and support terminal portions 17a, 17b provided in the end caps 16a, 16b.
管體2係由玻璃或樹脂等之透光性材料構成,如第2圖所示,為長狀且沿著縱長方向且其中一部分為開口,藉由開口端邊10a與開口端邊10b成為挾持有散熱器6之構造。又,實施例2如第1圖所示,管體2之開口端邊10a與開口端邊10b其構造亦與後述之散熱器6之溝部23a、23b咬合而成為被挾持著的構造。 The tubular body 2 is made of a light transmissive material such as glass or resin. As shown in Fig. 2, the tubular body 2 is long and has an opening along the longitudinal direction and a part thereof is opened by the open end side 10a and the open end side 10b.挟 holds the structure of the heat sink 6. Further, in the second embodiment, as shown in Fig. 1, the opening end side 10a and the opening end side 10b of the tubular body 2 are also engaged with the groove portions 23a and 23b of the heat sink 6 to be described later, and are held.
在習知之螢光燈上,係利用於真空狀態之管中置入微量之水銀蒸氣,於此流過電流使其發光,相對之,管體2係利用LED作為光源,只要為中空即可,不一 定需要完全密封。 In a conventional fluorescent lamp, a small amount of mercury vapor is placed in a tube in a vacuum state, and an electric current flows through the tube to emit light. In contrast, the tube 2 uses an LED as a light source, and as long as it is hollow, Not one It needs to be completely sealed.
LED光源部3譬如可為3mm×2.5mm之矩形狀晶片。另外,LED光源部3係為以螢光體覆蓋譬如藍色或比藍色波長更短之發光二極體之晶片構造且發出白光。又,LED光源部3只要能收納於基板4上之大小即可且非限定於上述大小。另外,LED光源部3也可使用發光層由有機化合物構成之有機EL。 The LED light source unit 3 can be, for example, a rectangular wafer of 3 mm × 2.5 mm. Further, the LED light source unit 3 is a wafer structure in which a light-emitting diode such as blue or shorter than a blue wavelength is covered with a phosphor and emits white light. Further, the LED light source unit 3 is not limited to the above size as long as it can be housed on the substrate 4. Further, as the LED light source unit 3, an organic EL in which the light-emitting layer is made of an organic compound can also be used.
LED光源部3,於基板4上面係以複數個且適當之間隔(或無間隙)在管體縱長方向配置成一列,發光時所生之熱能夠透過基板4傳導到散熱器6再從此將熱散開。 The LED light source unit 3 is arranged in a plurality of rows on the substrate 4 at appropriate intervals (or no gaps) in the longitudinal direction of the tube body, and heat generated during light emission can be transmitted to the heat sink 6 through the substrate 4 and then The heat spreads out.
基板4具有用來點亮LED之電路,於譬如由玻璃環氧樹脂構成之本體上形成有配線圖案。又,基板4之本體也可係鋁,陶瓷及玻璃等之具有散熱性之物體。 The substrate 4 has a circuit for lighting the LED, and a wiring pattern is formed on a body made of, for example, glass epoxy. Further, the body of the substrate 4 may be an object having heat dissipation properties such as aluminum, ceramics, and glass.
於基板4上面安裝有LED光源部3,於管體縱長方向且為長狀,設置讓背面與散熱器6緊密貼合。於LED點亮電路上產生之熱可透過基板4及散熱器6釋放出來。 The LED light source unit 3 is mounted on the upper surface of the substrate 4, and is elongated in the longitudinal direction of the tube body, and is provided so that the back surface and the heat sink 6 are in close contact with each other. The heat generated on the LED lighting circuit is permeable to the substrate 4 and the heat sink 6.
端蓋16a、16b係設置於管體2之兩端,使用與直管型螢光燈相同之端蓋而能與直管型螢光燈插入置換。另外,於各端蓋16a、16b皆具備有與直管型螢光燈相同之支撐端子部17a、17b。因此,LED螢光照明裝置1可直接安裝到與直管型螢光燈對應之照明器具插槽S(未圖示)中。 The end caps 16a and 16b are provided at both ends of the tubular body 2, and can be inserted and replaced with a straight tube type fluorescent lamp by using the same end cap as the straight tube type fluorescent lamp. Further, each of the end caps 16a and 16b is provided with the same support terminal portions 17a and 17b as the straight tube type fluorescent lamp. Therefore, the LED fluorescent lighting device 1 can be directly mounted in the lighting fixture slot S (not shown) corresponding to the straight tube type fluorescent lamp.
其次,茲參考第1、3、6、7、8及11圖詳細說 明導光擴散體5之構造。此導光擴散體5係設置用來讓從LED光源部3照射之光進行漫反射且設置成可擴大照射角度。因此,漫反射之光係加工成會進一步反射之形狀,譬如於管體縱長方向且為長狀,縱向剖面視略為新月型的形狀。又,導光擴散體5只要係可使漫反射之光進一步反射之形狀即可且並非限定於該形狀。 Secondly, please refer to the figures 1, 3, 6, 7, 8 and 11 for details. The structure of the light guiding diffuser 5. The light guiding diffuser 5 is provided to diffusely reflect light irradiated from the LED light source unit 3 and to increase the irradiation angle. Therefore, the diffuse reflection light is processed into a shape that is further reflected, for example, in the longitudinal direction of the tube body and elongated, and the longitudinal section is slightly crescent-shaped. Further, the light guiding diffuser 5 is not limited to this shape as long as it is a shape that allows the diffused light to be further reflected.
導光擴散體5主要係具備有:可接受從LED光源部3照射之光的平面狀之受光面9;保持散熱器6之一對傾斜面7a、7b;設置於各傾斜面7a、7b且與散熱器6之突部14a、14b卡合之溝部8a、8b;以及於曲面上接受於導光擴散體5內漫反射之光線,引起效率更佳之連鎖反射之曲面部11。如第1圖及第11圖所示,也可形成於導光擴散體5之各傾斜面7a、7b設置往管體縱長方向延伸之突部21a、21b之構造。 The light-guiding diffuser 5 mainly includes a planar light-receiving surface 9 that can receive light irradiated from the LED light source unit 3, and a pair of inclined surfaces 7a and 7b that hold the heat sink 6, and are provided on each of the inclined surfaces 7a and 7b. The groove portions 8a and 8b that are engaged with the projections 14a and 14b of the heat sink 6 and the light that is diffused and reflected by the light guide diffuser 5 on the curved surface cause a more efficient interlocking curved surface portion 11. As shown in FIGS. 1 and 11 , the inclined surfaces 7 a and 7 b of the light guiding diffuser 5 may be formed to have projections 21 a and 21 b extending in the longitudinal direction of the tubular body.
導光擴散體5係由透光性材料所構成,由於並非多層構造而為由單一素材(於實施例中係使用丙烯酸(acrylic))所形成,故可簡化製造步驟且抑制製造成本。又,導光擴散體5只要係由玻璃或樹脂等透明材料形成即可,並無限定素材。另外,導光擴散體5並非限定於透鏡型態,也可為薄膜型態。 The light-conducting diffuser 5 is made of a light-transmitting material, and is formed of a single material (acrylic used in the embodiment) instead of the multilayer structure, so that the manufacturing process can be simplified and the manufacturing cost can be suppressed. Further, the light guiding diffuser 5 is not limited to a material as long as it is formed of a transparent material such as glass or resin. Further, the light guiding diffuser 5 is not limited to the lens type, and may be in a film type.
受光面9係形成為平面狀,設置成與LED光源部3之表面面對面,其與LED光源部3之表面係為3mm。另外,受光面9及曲面部11間之導光擴散體厚度設為2.4mm。 The light-receiving surface 9 is formed in a planar shape, and is provided to face the surface of the LED light source unit 3, and is 3 mm from the surface of the LED light source unit 3. Further, the thickness of the light guiding diffuser between the light receiving surface 9 and the curved surface portion 11 was set to 2.4 mm.
此係依據光學設計而制定最適當數值。也就 是說,這是考慮到使受光面9及曲面部11越接近LED光源部3之表面,則曲面部11之曲率會變小且由於形狀接似平面,故較不易引起反射之連鎖,另外,從使受光面9及曲面部11越遠離LED光源部3表面,曲面部11之曲率會變大,會導致光集中到軌道方向,因此照度會產生不均勻現象。又,於實施例2中,如第11圖所示,受光面9及LED光源部3表面的距離係0.5mm。 This is based on the optical design to determine the most appropriate value. Also In other words, it is considered that the closer the light-receiving surface 9 and the curved surface portion 11 are to the surface of the LED light source unit 3, the smaller the curvature of the curved surface portion 11 is, and the shape is similar to the flat surface, so that the reflection is less likely to cause a chain of reflection. When the light-receiving surface 9 and the curved surface portion 11 are moved away from the surface of the LED light source unit 3, the curvature of the curved surface portion 11 becomes large, and the light is concentrated in the track direction, so that the illuminance is uneven. Further, in the second embodiment, as shown in Fig. 11, the distance between the light receiving surface 9 and the surface of the LED light source unit 3 is 0.5 mm.
受光面9之寬度係因為從平面上之LED所照射之光線角度為120度,故設定為可大致接受所有從LED光源部3照射的直線光。 The width of the light-receiving surface 9 is such that the angle of the light irradiated from the LED on the plane is 120 degrees, so that it is possible to substantially accept all the linear light irradiated from the LED light source unit 3.
設置於傾斜面7a、7b之溝部8a、8b,係藉由插入到設置於散熱器6的保持部12之突部14a、14b而卡合,使導光擴散體5嵌合於散熱器6。又,也可將此溝部8a、8b作成突形狀而將突部14a、14b作成溝形狀。另外,有關傾斜面7a、7b與散熱器6之卡合方式,可為滑動插入或利用彈力使其嵌合。 The groove portions 8a and 8b provided on the inclined surfaces 7a and 7b are engaged by being inserted into the projections 14a and 14b provided in the holding portion 12 of the heat sink 6, and the light guide diffuser 5 is fitted to the heat sink 6. Further, the groove portions 8a and 8b may have a projecting shape and the projections 14a and 14b may have a groove shape. Further, the manner in which the inclined faces 7a, 7b are engaged with the heat sink 6 can be slidably inserted or fitted by an elastic force.
設置於導光擴散體5之傾斜面7a、7b的溝部8a、8b及曲面部11間之導光擴散體的厚度為1mm。此係依據光學設計而制定最適當數值。也就是說,這是考慮到於導光擴散體內進行漫反射之光線係射向安裝器具側(屋頂面及璧面等),其之光線會因照明器具之反射板而擴大。又,實施例2,如第11圖所示,其構造也可為如下:藉由讓導光擴散體5之突部21a、21b插入到後述之散熱器6的溝部22a、22b而卡合,使導光擴散體5嵌合到散熱器6。 The thickness of the light guiding diffuser provided between the groove portions 8a and 8b of the inclined surfaces 7a and 7b of the light guiding diffuser 5 and the curved surface portion 11 is 1 mm. This is based on the optical design to determine the most appropriate value. That is to say, it is considered that the light which is diffused and reflected in the light-conducting diffusing body is directed toward the mounting tool side (the roof surface and the top surface, etc.), and the light thereof is enlarged by the reflecting plate of the lighting fixture. Further, in the second embodiment, as shown in FIG. 11, the structure may be such that the projections 21a and 21b of the light-conducting diffuser 5 are inserted into the groove portions 22a and 22b of the heat sink 6 to be described later, and then engaged. The light guide diffuser 5 is fitted to the heat sink 6.
曲面部11係形成平緩之曲面狀而可於導光擴散體5內引起經進行漫反射的光之連鎖。因在導光擴散體5內進行漫反射而擴散之光,可從曲面部11之全面而廣範圍地照射。 The curved surface portion 11 is formed into a gently curved shape to cause interlocking of light that is diffusely reflected in the light guiding diffuser 5. The light diffused by the diffused reflection in the light guiding diffuser 5 can be irradiated from the entire surface of the curved surface portion 11 in a wide range.
導光擴散體5係於表面藉由壓縮機(Compressor)進行噴塗混有研磨材料之壓縮空氣之噴砂(blast)加工,藉由噴砂加工所形成之凹凸的尺寸係從1μ至1mm,利用曲面部11之形狀及藉由此噴砂加工形成於表面的凹凸可讓從LED光源部3受光之光線進行漫反射,藉由光學設計技術可自由地改變發光方向。又,導光擴散體5之表面凹凸並非限於噴砂加工,也可使用金屬模具等之一體成型來形成。 The light-guiding diffuser 5 is subjected to blast processing by spraying a compressed air of a polishing material by a compressor (Compressor), and the size of the unevenness formed by the sandblasting process is from 1 μ to 1 mm, and the curved surface portion is used. The shape of 11 and the unevenness formed on the surface by the sandblasting process allow the light received from the LED light source unit 3 to be diffusely reflected, and the light-emitting direction can be freely changed by optical design techniques. Further, the surface unevenness of the light guiding diffuser 5 is not limited to sandblasting, and may be formed by one body molding such as a metal mold.
其次,茲參考第1、4及12圖並說明散熱器6之構造。此散熱器6係被小型化至尺寸大略與導光擴散體5相同,收容有LED光源部3及基板4,其主要具備有:往管體2內側方向突出之保持部12;位於保持部12兩側面之凹部13a、13b;用來與導光擴散體5嵌合之突部14a、14b;以及位於基板4之背面側且配列於管體縱長方向之複數個鰭片部15。 Next, reference is made to Figures 1, 4 and 12 and the construction of the heat sink 6 will be described. The heat sink 6 is miniaturized to have the same size as the light guide diffuser 5, and houses the LED light source unit 3 and the substrate 4, and mainly includes a holding portion 12 that protrudes toward the inside of the tubular body 2, and is located at the holding portion 12. Concave portions 13a and 13b on both side surfaces, projections 14a and 14b for fitting with the light guide diffuser 5, and a plurality of fin portions 15 on the back side of the substrate 4 and arranged in the longitudinal direction of the tube.
散熱器6係譬如由鋁等輕量且熱傳導性較高之材料構成,使保持部12、凹部13a、13b、突部14a、14b及鰭片部15一體成型為縱向剖面視時略為字狀。又,實施例2之散熱器6,如第12圖所示,使保持部12、溝部22a、22b、溝部23a、23b及鰭片部15一體成型為縱向剖面視時為字狀,也可為設置分隔溝部22a、22b與溝部 23a、23b之突部24a、24b的構造。 The heat sink 6 is made of a material such as aluminum which is lightweight and has high thermal conductivity, and the holding portion 12, the recessed portions 13a and 13b, the projections 14a and 14b, and the fin portion 15 are integrally formed into a longitudinal cross-sectional view. Word shape. Further, in the heat sink 6 of the second embodiment, as shown in Fig. 12, the holding portion 12, the groove portions 22a and 22b, the groove portions 23a and 23b, and the fin portion 15 are integrally formed into a longitudinal cross-sectional view. The shape of the shape may be such that the projections 24a and 22b and the projections 24a and 24b of the groove portions 23a and 23b are provided.
散熱器6係與基板4背面密合且設置成可嵌合到導光擴散體5,故可透過鰭片部15更有效釋放出從基板4及導光擴散體5之接觸面傳導的熱。又,此突部14a、14b為溝狀也將溝部8a、8b設為突狀。 Since the heat sink 6 is in close contact with the back surface of the substrate 4 and is provided to be engageable with the light guide diffuser 5, the heat transmitted from the contact faces of the substrate 4 and the light guide diffuser 5 can be more effectively transmitted through the fin portion 15. Further, the projections 14a and 14b have a groove shape and the groove portions 8a and 8b have a projecting shape.
散熱器6利用使鰭片部15的各前端描繪的軌跡成為剖面時呈圓弧狀而與管體2組合時,整體上就等同圓筒狀之一般螢光燈型態,可安裝現有之直管型螢光燈用之端蓋。又,於實施例2之鰭片部15,如第12圖所示,係往管體縱長方向延伸的板狀片,且以8.4mm的寬度等間隔具備4片鰭片的構造。另外,鰭片部15,各鰭片之前端厚度為0.8mm且位於溝部最深部分之鰭片厚度為1.1mm,鰭片部15之間的溝部深度最大為3.3mm。 When the trajectory drawn by the tip end of the fin portion 15 is formed in an arc shape in a cross section and combined with the tubular body 2, the heat sink 6 is equivalent to a cylindrical general fluorescent lamp type as a whole, and can be mounted directly. End caps for tubular fluorescent lamps. Further, as shown in Fig. 12, the fin portion 15 of the second embodiment has a structure in which four fins are provided at equal intervals of 8.4 mm in a plate-like piece extending in the longitudinal direction of the tubular body. Further, in the fin portion 15, the thickness of the front end of each fin is 0.8 mm, the thickness of the fin located at the deepest portion of the groove portion is 1.1 mm, and the depth of the groove portion between the fin portions 15 is at most 3.3 mm.
接著,說明LED螢光照明裝置1之動作。首先,使用者若接上電源,則電源會供應給基板之電路使LED光源部3發光。從LED光源部3照射之光的角度為120度,設置成與LED光源部3面對面,導光擴散體5之受光面9係接受大致所有從LED光源部3照射的光。 Next, the operation of the LED fluorescent lighting device 1 will be described. First, when the user connects the power source, the power supply is supplied to the circuit of the substrate to cause the LED light source unit 3 to emit light. The angle of the light irradiated from the LED light source unit 3 is 120 degrees, and is disposed to face the LED light source unit 3, and the light receiving surface 9 of the light guide diffuser 5 receives substantially all of the light emitted from the LED light source unit 3.
於導光擴散體5之受光面9受光之光線係透過導光擴散體5內,且藉由在曲面部11之形狀及導光擴散體5之表面進行噴砂加工,於曲面部11進行漫反射,使漫反射之光進一步透過導光擴散體內而於曲面部11進行漫反射。藉由此漫反射之連鎖可讓光大範圍地在導光擴散體5內擴散。 The light received by the light receiving surface 9 of the light guiding diffuser 5 is transmitted through the light guiding diffuser 5, and is subjected to sandblasting on the surface of the curved surface portion 11 and the surface of the light guiding diffuser 5 to perform diffuse reflection on the curved surface portion 11. The diffuse reflection light is further diffused and reflected on the curved surface portion 11 through the light guide diffusion body. By this linkage of diffuse reflection, light can be widely diffused in the light guiding diffuser 5.
於導光擴散體5內大範圍地擴散之光係從導 光擴散體5之曲面部11往管體2照射,管體2由於係由透光性材料所構成,故往管體2照射之光就直接透過管體2,從管體2全周圍面往外部空間均勻地照射。 a light system that diffuses widely in the light-diffusing diffuser 5 The curved surface portion 11 of the light diffuser 5 is irradiated to the tube body 2, and the tube body 2 is made of a light transmissive material. Therefore, the light irradiated to the tube body 2 directly passes through the tube body 2, from the entire circumference of the tube body 2 The external space is uniformly illuminated.
LED螢光照明裝置1中管體2係挾持散熱器6,於使用時讓散熱器6設置成位於安裝器具側。散熱器6被小型化至尺寸大略與導光擴散體5相同,再者藉由散熱器6所遮掩的部分也變少,故從管體2照射之光的照射角度可擴大到340度。藉此,光到達安裝器具側(屋頂面、璧面),其光線被照明器具之反射板擴大,故事實上,照射範圍可擴大到360度且不會給使用者帶來不協調感覺。另外,導光擴散體5之形狀可變更成因應於目的之形狀,譬如也可改變成使用者所期望之照射角度‧方向。 In the LED fluorescent lighting device 1, the tube body 2 holds the heat sink 6, and the heat sink 6 is placed on the side of the mounting tool when in use. The heat sink 6 is miniaturized to have the same size as the light guide diffuser 5, and the portion covered by the heat sink 6 is also reduced. Therefore, the irradiation angle of the light irradiated from the tube 2 can be expanded to 340 degrees. Thereby, the light reaches the mounting tool side (the roof surface, the kneading surface), and the light is enlarged by the reflecting plate of the lighting fixture, so that the irradiation range can be expanded to 360 degrees without giving the user an uncomfortable feeling. Further, the shape of the light guiding diffuser 5 can be changed to a shape according to the purpose, and can be changed, for example, to an irradiation angle ‧ direction desired by the user.
最後,顯示LED螢光照明裝置1之特性。第9圖為顯示依據LED螢光照明裝置1之實測值之照射範圍的圖表。從第9圖可知,來自LED光源部3之光照射到大略340度。有關未照射之剩餘角度20度,如前述所言,形成可於照明器具之反射板藉由反射使光到達該處之構造。 Finally, the characteristics of the LED fluorescent lighting device 1 are displayed. Fig. 9 is a graph showing the irradiation range according to the measured value of the LED fluorescent lighting device 1. As can be seen from Fig. 9, the light from the LED light source unit 3 is irradiated to approximately 340 degrees. Regarding the remaining angle of 20 degrees without irradiation, as described above, a configuration is formed in which the reflection plate of the lighting fixture reaches the light by reflection.
表1為依據LED螢光照明裝置1之實測值之照度與其他公司之比較表。 Table 1 is a comparison table of the measured values of the measured values of the LED fluorescent lighting device 1 with other companies.
如表1所式,可知LED螢光照明裝置1不但可抑制消耗電力且演色性高,可發出接近自然光且不刺激眼睛之 光。如此可證明LED螢光照明裝置1具有優越的特性。 As shown in Table 1, it can be seen that the LED fluorescent lighting device 1 can suppress power consumption and has high color rendering property, and can emit near natural light without irritating the eyes. Light. This proves that the LED fluorescent lighting device 1 has superior characteristics.

The inside of 5 is diffusely reflected by the unevenness of the surface. Further, since the light guiding diffuser 5 is processed into a shape that further reflects the reflected and scattered light, interlocking reflection of light is generated, and the light from the LED light source unit 3 can be diffused in multiple directions.
另外,若藉由本發明,於LED光源部3利用有機電致發光(以下稱之為有機EL),提高發光效率並較不易發熱,且有機EL本身會發光,故可壓低電壓、減少消耗電力。 Further, according to the present invention, organic light-emitting (hereinafter referred to as organic EL) is used in the LED light source unit 3 to improve luminous efficiency and to generate heat, and the organic EL itself emits light, so that voltage can be reduced and power consumption can be reduced.

Further, since the shape of the light-conducting diffuser 5 is formed to have a crescent-shaped shape in the longitudinal cross-sectional view, the diffuse reflection light can be received in the light-guide diffuser 5 on the crescent-shaped curved surface, so that The effective reflection is interlocked, and the entire surface of the crescent-shaped curved surface portion 11 of the light guiding diffuser 5 is widely irradiated.
另外,若藉由本發明,於導光擴散體5之傾斜 面7a、7b設置有溝部(或突部)8a、8b,藉由在散熱器6設置突部(或溝部)14a、14b,使得導光擴散體5之傾斜面7a、7b與散熱器6可相互嵌合而可防止導光擴散體5在管體2內掉落,同時,可將導光擴散體5之熱與LED光源部3及基板4的熱一同釋放。 In addition, according to the present invention, the tilt of the light guiding diffuser 5 The surfaces 7a, 7b are provided with grooves (or protrusions) 8a, 8b, and by providing protrusions (or grooves) 14a, 14b in the heat sink 6, the inclined faces 7a, 7b of the light-conducting diffuser 5 and the heat sink 6 can be The light-conducting diffuser 5 can be prevented from falling in the tubular body 2 while being fitted to each other, and the heat of the light-guiding diffuser 5 can be released together with the heat of the LED light source unit 3 and the substrate 4.
