Description of the invention: [Technical field to which the invention belongs], the side of the side of the electrodeless lamp is a shadow-length structure, especially an electrodeless one capable of improving luminous efficiency and uniformity of illumination of a dog. Flat panel construction. [Prior Art] Lighting fixtures are indispensable daily necessities for people's lives. In order to provide people with more stable and different needs, there are fluorescent lamps, mercury lamps, and the most advanced electronic energy-saving lamps. The content device is used to achieve the best lighting effect. Generally, the fluorescent tubes generally used in the present invention mainly use a filament electrode which is disposed in two sections of the lamp tube, and cooperates with the inert gas filled in the lamp tube and the fluorescent material coated on the inner wall of the lamp tube, and the electrons are discharged when the electrode is discharged. The fluorescent material that strikes the inner wall of the tube 'transmits light' to produce a source of illumination. Since the shape of a general fluorescent lamp is _ subjected to atmospheric pressure, it can only be made into a spherical shape and a round tubular shape. Although some people have made the fluorescent tube into a flat shape to provide a large surface light source, • When the lamp tube is made, the internal air must be completely exhausted. However, the process is to create a negative pressure in the inside of the lamp, and the flat lamp is in the process of vacuum suction. In the middle region, a depression or crack occurs in the central region, resulting in poor quality. China Patent Publication No. 5 9 4 3 3 0 discloses a cold cathode planar lamp structure in which a portion between two long strip-shaped grooves on a plate-like substrate or a sandwich between two plate-shaped substrates is formed. The wavy structure is supported to support the plate-shaped substrate to prevent the plate-shaped substrate from being deformed or broken by external force or negative pressure; however, the cold cathode 5 1329338 flat lamp still has the following disadvantages in use. The description is as follows: 1. After the conventional cold cathode flat lamp is discharged through the electrode, a part of the light passes through the inner wall of the cavity where the fluorescent material is applied, and then passes through the plate-shaped substrate to the outside, but actually the light In the process of traveling in the cold cathode flat lamp, after being in surface contact with the inner wall of the cavity, the inner wall surface is penetrated, and since the inner wall of the coating of the fluorescent material and the plate substrate are two Different media, the refractive index is not the same at all, so that the light is refracted and blocked in two segments, which leads to a significant reduction in the luminous efficiency of conventional cold cathode planar lamps. 1. After the cold cathode flat lamp for S is discharged through the electrode, a part of the light is refracted through the inner wall of the cavity and the plate substrate, and then travels to the outside, and the other part of the light passes directly through the plate substrate to Externally, the light of the two different paths causes the cold cathode planar lamp to exhibit two different luminous intensities, thus seriously affecting the uniformity of the illumination of the cold cathode planar lamp. After that, the inventors proposed an improved structure and filed a patent application with the squad, and obtained a new patent No. M283310, mainly i, an electrodeless panel lamp structure, which is composed of a first plate and a The second slabs are corresponding to each other, and at least one of the slabs is transparent, and at least one frame wall is disposed around the corresponding ring of the two slabs, defining a closed chamber ′ and a magnetic core is disposed outside the second slab. At least one of the support columns is integrally extended on the inner side of one of the flat plates, and the support column gradually forms a convergence from the root portion to the free end (ie, the top contact end), so that the electromagnetic wave of the magnetic core excites the fluorescent material to illuminate and illuminate, mainly By the point contact between the light and the support column, the possibility of shadow generation is reduced, and the blocking of the light is reduced. Although the pattern of "point contact" can slightly eliminate the light shadow, the actual formation of the support column is found to be a point turn, and there is still a dot-like shadow. Therefore, there is still considerable room for improvement. SUMMARY OF THE INVENTION There is a cloud in the foregoing prior art that is not perfect, the present inventor thinks that a dog-free luminous efficiency and a luminous uniformity of the electrodeless flat lamp hybrid shadow elimination structure is the main purpose. The technical means used in the prior art to solve the previous problems is mainly to design an electrodeless flat lamp structure, which is arranged by a first plate and a second plate having a light transmitting ridge, and is matched with the circumference of the two plates. The ring is provided with at least a frame wall, the boundary is closed, and the inner side of the second plate is integrally extended with a plurality of supports (four) riding the first plate. The county is required to form a concave surface corresponding to the paste position of the first plate corresponding to the support column. The light is shaped by the wire to the concave fox face, and the shadow caused by the top of the support column is eliminated by the diffusing phenomenon of the shaft of the innumerable reflection. [Embodiment] Hereinafter, the structure, features and embodiments of the present invention will be described by way of illustration, and the reviewers will be further aware of the present case. The following is based on the foregoing novel content, and the preferred embodiment is as follows: Referring to the first figure, and in conjunction with the second and third figures, the present invention is a closed chamber (4) having no electrodes at both ends thereof. The structural design of the lamp is mainly caused by the coupling of the alternating electromagnetic field to make the flat lamp bright, so it is called an electrodeless lamp, which mainly comprises: a first flat plate (1): having light transmissivity, and the invention is mainly for the first The flat plate (1) corresponds to the top contact position of the support column (5) described later, and forms a relatively concave curved surface (1 1 ). The light is incident on the concave curved surface (11) by the light 132*9338, so that the light forms an infinite number of reflection states. And by the diffuse phenomenon formed by the innumerable reflections, and by the diffusion of the light, the shadow caused by the "top" of the branch (5) described later can be eliminated. In the implementation of the present invention, the concave orphan plane (1 1 ) of the first flat plate (1) is formed with a groove (1 〇 ) on the inner side, and the groove surface is a concave orphan surface (11). In addition, as shown in the seventh figure, the concave flat surface of the first flat plate (1) of the present invention may be further formed by forming a convex body (1 2 ) on the outer side and using the convex shape. The inner curved surface of the body (1 2 ) forms a concave curved surface (1 1 A ). The two embodiments are disclosed to enable the *light to be sufficiently eliminated for the point-like shadow formation. a second plate (2): the first plate (2) corresponds to the first plate (1), and at least one frame wall (3) is arranged around the corresponding two plates to define a closed chamber ( 4), the closed chamber (4) is filled with an inert gas (4 丄) and a layer of fluorescent material (42) is coated on the inner wall surface, and a magnetic core is disposed outside the second plate (2) (4 3 ); Again, the frame wall (3) can be selected as a light transmissive or opaque interface. Moreover, as shown in the eighth figure, the magnetic core may also be replaced by a conductive sheet (43a) or other equivalent material or element sufficient to excite or induce the fluorescent material (42), and the conductive sheet (4 3 A) ) is provided on the outer peripheral surface of the first flat plate (1) or on the periphery of the frame wall (3) (not shown).
又’請參閱第九圖所示，本發明於第七圖所顯示疊設一複 合單元之實施例時，該磁芯亦同樣可以一導電片（43B )或其他足以激發或講發螢光材料（4 2)之等效材料或元件 8 取代’而該導電片（4 3 B)係分別設於第一平板（l)與第 二平板（2)之外側表面周緣。 本發明於第二平板（2)内侧一體延伸複數個支撐柱（5 )(亦可反向由第一平板延伸至第二平板），該支撐柱（5 )較 佳之實施例係由根部向自由端逐漸形成收斂’令該磁芯（4 3 )之電磁波激發點亮時，藉由光線與該支撐柱之間的點接觸， 更縮小陰影產生之可能性。 如第四圖及第五圖所示，係本發明之另一實施例，其中該 第一平板（1)與該第二平板（2)以及兩平板間對應之不透 光框壁（3)界定為一封閉腔室（4)複設為兩組相同之單元 ，且該磁芯（4 3)係夾設於兩個相同單元之第二平板（2) 間，以令該兩單元之第一平板（i)分別形成二透光介面。 請參閱第六圖一A至第六圖一；Η所示，其中該支撐柱（5 )可以選擇多種排列型態’佈列於該第二平板（2)之内側面 上，且藉由該支撐柱（5)支撐於該第一平板（1)及該第二 平板（2)之間，使處於抽真空之流程時，所形成的負壓不會 造成兩平板中央區域的凹陷或破裂外，且同時可藉由該支撐柱 (5)錐狀體的設計，使本發明發光點亮時，該光線則與該支 撐柱（5)形成點接觸，更縮小陰影產生之可能性，再加上該 支撐柱（5)與該兩平板係屬一體延伸之結構且為相同的材 質，其折射率大抵相同，故每道光線在行進的過程中，較不會 因該支撐柱（5)的設置，而使發光強度有任何的變化，而直 接穿過該封閉腔室（4)的壁面至外界，進而增加其發光的均 勻度。 本發明構造特色所產生之效果： 、本發明中支撐柱的結構設計，除可以儘量降低阻遮到光線 的行進，故其發光效率及發光的均勻度較佳，且支撐柱與 兩平板係屬一體延伸之結構，且材質亦完成相同，所以每 道光線在行進的過程中，該支撐柱與兩平板的折射率大抵 相同，而使發光強度不會有任何的變化，進而提昇發光的 均勻度。 二、另一方面，本發明所提供之優點更在於，由於本發明所提 供之凹弧面可以當光線照射時，入射光線的反射會遵守反 射定律，即入射光、反射光及法線均在同一平面上，且入 射光、反射光各位於法線的兩侧，即入射角與反射角相等 。此反射定律適用於任何形狀的反射面。當反射面為曲面 時’把母一條光線的射落點近旁的微小範圍視作面，因每 一面積素的法線都有不同的方向，故它們反射的光線亦非 同一方向，而形成所謂的漫射。 三、基於愛因斯坦在1905年提出「光的波粒二象性」，認為光 既是波動，也是粒子。到了 1924年，法國物理學家德布 羅義更進一步提出：不單是光，任何物質粒子都具有「波 粒二象性」。藉由波動與粒子對於本發明中支撐柱頂觸於 第一平板之微小間隙形成無孔不入之填補。以及本發明在 該凹弧曲面上所形成之光線漫射，足以消除支撐柱頂觸時 所造成之陰影，使得本發明所屐現之光線均勻。 1329338Further, please refer to the ninth figure. When the embodiment of the present invention is shown in the seventh figure, the magnetic core can also be a conductive sheet (43B) or other sufficient fluorescent material to be excited or emitted. (4 2) The equivalent material or element 8 is substituted for 'the conductive sheet (4 3 B) is provided on the outer peripheral surface of the first flat plate (1) and the second flat plate (2), respectively. The invention integrally extends a plurality of support columns (5) on the inner side of the second plate (2) (may also extend from the first plate to the second plate in reverse), and the preferred embodiment of the support column (5) is free from the root When the end gradually forms a convergence, when the electromagnetic wave of the magnetic core (4 3 ) is excited to illuminate, the possibility of shadow generation is further reduced by the point contact between the light and the support column. As shown in the fourth and fifth figures, another embodiment of the present invention, wherein the first plate (1) and the second plate (2) and the opaque frame wall (3) corresponding to the two plates Defined as a closed chamber (4) is set to two sets of identical units, and the magnetic core (43) is sandwiched between two second plates (2) of the same unit to make the two units A flat plate (i) forms two light transmissive interfaces, respectively. Please refer to FIG. 1A to FIG. 1A; wherein the support column (5) can be arranged in a plurality of arrangement patterns on the inner side surface of the second plate (2), and The support column (5) is supported between the first plate (1) and the second plate (2) so that the negative pressure formed during the vacuuming process does not cause depression or cracking of the central portion of the two plates. At the same time, by the design of the support column (5) cone, when the light of the invention is illuminated, the light forms a point contact with the support column (5), thereby reducing the possibility of shadow generation, and adding The supporting column (5) and the two flat plates are integrally extended and have the same material, and the refractive index thereof is substantially the same, so that each light is not in the process of traveling, and is not affected by the supporting column (5). It is set to have any change in luminous intensity, and directly passes through the wall surface of the closed chamber (4) to the outside, thereby increasing the uniformity of its illumination. The effect of the structural features of the present invention: The structural design of the support column in the present invention, in addition to minimizing the obstruction of light to travel, so that the luminous efficiency and uniformity of illumination are better, and the support column and the two plates are The structure of the integral extension and the material are also the same, so that the refractive index of the support column and the two plates are substantially the same during the traveling of each light, so that the luminous intensity does not change, thereby improving the uniformity of the illumination. . 2. On the other hand, the present invention provides the advantage that, since the concave arc surface provided by the present invention can be irradiated with light, the reflection of the incident light will follow the law of reflection, that is, the incident light, the reflected light, and the normal are On the same plane, the incident light and the reflected light are respectively located on both sides of the normal line, that is, the incident angle is equal to the reflection angle. This reflection law applies to reflective surfaces of any shape. When the reflecting surface is a curved surface, 'the tiny range near the falling point of the mother's light is regarded as the surface. Since the normals of each area have different directions, the reflected light is not in the same direction. The diffuse. 3. Based on Einstein's "wave-particle duality" of light in 1905, light is considered to be both a wave and a particle. In 1924, the French physicist De Broglie further proposed that not only light, but also any matter particles have "wave-particle duality". The non-pervasive filling is formed by the fluctuations and the particles for the minute gap of the support column in the first plate of the present invention. And the light diffused on the concave curved surface of the present invention is sufficient to eliminate the shadow caused by the top of the support column, so that the light of the present invention is uniform. 1329338
