It is also produced in a state of pseudo-parallel light, thereby reducing the loss of light and reducing the use of luminescent materials, so that light can be effectively and fully utilized. [Prior Art] Light Emitting Diode (LE: D) is a kind of semiconductor component. Due to its small size, long life, and low power consumption, it has been widely used in various fields of optoelectronics and daily life. Since the light-emitting diode is a voltage applied, a bright semiconductor is emitted instead of being heated by the filament. In the field of technology, in the development of semiconductors and integrated circuits, the "light-emitting elements" of semiconductor products used for illuminating and the semiconductor products of wire-bonded wires are the same as those used by "light-bovines". The electricity is converted into light, and the latter transforms the light into electricity. From the beginning as the turning light element, the LED (the development goal of the autumn two poles - straight pursuit of how to "brighter" and "more diverse":: Very large r Step; electro-optical-electrical transformation is not only for the eyes to see == to achieve the purpose of transmitting electrical signals. Cattle conductor laser, etc., using light to two electric rafts, the material illuminator (1G) includes two electrodes, and The two electrodes are divided into an anode (11) and a cathode (12) I pole and are provided with - for generating a reflection effect (12) on the disc (13), and the disc (13) is equipped with 5 I33H09 s. The polar body (14), wherein the disk (13) is also provided with phosphor powder, whereby light is generated by the light-emitting diode (14), and then different colors are generated by fluorescence, and then the light is emitted. A wiring (15) is provided between the polar body (i 4) and the anode (丄丄) for connecting the two to each other at the anode (1 1 ) A lead wire (15) is connected under the cathode (12) for connecting the power source to illuminate the illuminant (10), and the illuminant (1 〇) is covered with a transparent resin and has a lens thereon ( 16) to adjust the range of light and also to direct the light to the quasi-parallel light and the lens (16) can be used for various shapes to change the directivity, and many are made into a convex or square shape, and its common application It is car lights, traffic lights, flashlights, and so on.
另一先前技術如第二圖所示，發光體（2 〇)包括有二電極 陰極（2 2)與陽極（2 3)，同樣的在陽極（2 3)上裝設有 -發光二極體晶粒（2 4)，並且在陽極（2 3)與發光二極體 晶粒（2 4 )上皆有-絲（2 6 )供兩者相互連接，不同的是 在發光體（2 〇 )裝§曼-本體外殼（2 1 )，本體外殼（2 1)内 裝設有-拋物曲面（2 5 ) ’其射拋物曲面（2 5 )驗係正對發 光二極體晶粒（2 4)之發光面’藉以將發光二極體晶粒（2 4) 發射出之光狂為擬平行光射出使其光線射出。 “然而前述二種先前技術，其中第一圖所示之發光體⑴ ^將光能量加大财光更為集中，需將其透鏡（工6 )加 見加大’且要將發光二極體晶粒（工4)與透鏡（16)門的距 ㈣㈣嶋，吻嶋的材 6 而在第二圖中所示之發光體（2 Ο )，其為了減少光的損失 與將光導向更為集中，其亦必須將發光二極體晶粒（24)與抛 物曲面（2 5) Μ的距離拉大，如此拋物曲面（2 5)必需使用 較大的拋物面設計’故其所需祕的材料與成本亦相對的就會增 加’而其上兩者之設計皆無法配合導絲人光面狹小之設計，若 要將以上兩種習知之lED發光源構造應用在液晶螢幕之導光板上 將無法使液晶f幕輕便及美觀化，故其並無法完全符合現今 求。 又，如我國專利證號：233698「發光二極體燈及其製造方法」， 揭露一種發光二極體燈，係包括一燈芯及一反光罩，該燈芯上設 有發光二極體晶片，其位於該反光罩之反射曲面之焦點上，且該 發光二極體晶片之發光面係正對反光罩之反射曲面，且與反光罩 之縱向軸線成0到85度夾角，然而由於該先前技術對於光線之投 射仍然必須將發光二極體晶粒與拋物曲面間形成概約正面之對 應，且為因應對焦，發光二極體晶粒與透光罩間之軸向距離仍然 必須考篁相當之間距，因此對於輕薄短小需求，仍有空間型態上 無法滿足之缺憾。 綜合前開各種先前技術，共同之問題主要在於由於未能充分 利用之光線反射之特性以及空間佈局之效益性，因此無法達成令 發光二極體之發光體空間運用更為效率化，以致於無法達成輕薄 短小之目的。 1331409 « « 【發明内容】 本發明主要之目的在於設計一種發光二極體光源體，主要包 括一反光殼板，該反光殼板之斷面（二維狀態下之剖面或平面狀 態）係呈一由内向外凸弧（内側相對凹弧）之拋物線狀’且該拋 物線之一侧與一基座板之内側相鄰，且基座板外侧鄰接一罩殼， 該罩殼斷面至少形成一向反光殼板相對凸弧之反光段，以及與反 光殼板相連之透光段，該基座板設至少一發光二極體晶體，該發 Φ 光二極體晶體之正面發光面向，斷面狀態下延伸之假想線通過該 反光殼板，且基座板於斷面狀態下，其與罩殼鄰接點，與該假想 線平行之假想延伸線亦通過該反光殼板。 由於本發明之使得發光二極體晶體之正面發光面向，並非直 接面對罩殼，而是透過一種折射光線所透出，因此本發明中之發 光二極體晶體並無直接之必要，考量面對罩殼之距離以及考量焦 距問題；因此，自然無須形成直線距離與長度之限制；換言之， 本發明乃是利用空間型態之轉折而使得發光二極體晶體對於透光 籲之輝度不影響之情況下，卻能創造一種空間充分利用之效果。 【實施方式】 以下藉由圖式說明本發明之内容、特點以及實施例，俾使貴 審查委員對於本發明有更進一步之理解。 凊參閱第三圖與第四圖所示，本發明係關於一種發光二極體 光源體，該發光二極體之光源體（3)主要包括： 一反光殼板（3 1 )’該反光殼板（3 1)之斷面係呈一由内 8 I33H09 • 向外凸弧（内側相對凹弧）之拋物線狀，且該拋物線之一側與一 基座板（3 0)之内側相鄰，且基座板（3 〇)外側鄰接一罩殼 (3 2 )，該罩殼（3 2 )可以為透明樹脂或具有透明性質之材料 製，又，該透明樹脂含有螢光成份；且，該罩殼（3 2)斷面至 少形成一向反光殼板相對凸弧之反光段（3 2 A )，以及與反光殼 板相連之透光段（3 2 B )，該透光段（3 2 B )與反光段（3 2 A)形成一轉折緣（3 2 C)(在二維平面所呈現則為轉折點）。 _ 該基座板（3 〇)至少設一發光二極體晶體（3 3)(亦可為Another prior art, as shown in the second figure, the illuminant (2 〇) includes a two-electrode cathode (22) and an anode (23), and the same anode (23) is provided with a light-emitting diode. The crystal grains (24) and the filaments (2 6 ) are connected to each other on the anode (23) and the light-emitting diode crystal grains (2 4 ), and the difference is in the illuminant (2 〇) Install the 曼Man-body shell (2 1 ), the body shell (2 1) is equipped with a parabolic surface (2 5 ) 'the parabola surface (2 5 ) is perpendicular to the illuminating diode dies (2 4 The light-emitting surface is used to illuminate the light emitted by the light-emitting diode (2 4) into pseudo-parallel light to emit light. "However, the two prior art mentioned above, in which the illuminant (1) shown in the first figure is more concentrated in increasing the light energy, it is necessary to increase the lens (work 6) and to have the light-emitting diode The distance between the die (4) and the lens (16) (4) (4) 嶋, the material of the kiss 6 6 and the illuminant (2 Ο ) shown in the second figure, in order to reduce the loss of light and direct the light Concentration, it must also enlarge the distance between the light-emitting diode (24) and the parabolic surface (25), so the parabolic surface (25) must use a larger parabolic design. Compared with the cost, it will increase', and the design of the two can't match the narrow design of the guide wire. If you want to apply the above two conventional lED light source structures to the light guide of the LCD screen, you will not be able to apply it. The liquid crystal f screen is light and beautiful, so it cannot fully meet the requirements of today. Moreover, as disclosed in Chinese Patent No. 233698 "Light-emitting diode lamp and its manufacturing method", a light-emitting diode lamp is disclosed, which includes a a wick and a reflector having a light-emitting diode chip thereon, Located on the focal point of the reflective surface of the reflector, and the light emitting surface of the LED wafer is opposite to the reflective surface of the reflector, and is at an angle of 0 to 85 degrees with the longitudinal axis of the reflector, however, due to the prior art The projection of the light must still form an approximate frontal relationship between the light-emitting diode die and the parabolic surface, and in order to focus, the axial distance between the light-emitting diode die and the transparent cover must still be considered. Therefore, for the short and light demand, there is still a lack of space type. In addition to the various prior art technologies, the common problem lies in the fact that due to the insufficiency of the characteristics of light reflection and the effectiveness of the spatial layout, it is impossible to achieve a more efficient use of the illuminator space of the light-emitting diode, so that it cannot be achieved. Light and short. 1331409 « « 【 SUMMARY OF THE INVENTION The main object of the present invention is to design a light-emitting diode light source body, which mainly comprises a reflective shell plate, and the cross-section of the reflective shell plate (a cross-section or a planar state in a two-dimensional state) is one a parabolic shape of the convex arc from the inside to the outside (the inner side is opposite to the concave arc) and one side of the parabola is adjacent to the inner side of a base plate, and the outer side of the base plate abuts a casing, and the casing cross section forms at least one direction of reflection a reflective section of the shell plate opposite to the convex arc, and a light-transmissive section connected to the reflective shell plate, wherein the base plate is provided with at least one light-emitting diode crystal, and the front surface of the light-emitting diode body emits light, extending in a cross-sectional state The imaginary line passes through the reflective shell, and the base plate is in a cross-sectional state, and the imaginary extension line parallel to the imaginary line passes through the reflective shell. Since the front side of the light-emitting diode crystal is facing directly, instead of directly facing the cover, but is transmitted through a refracting light, the light-emitting diode crystal of the present invention is not directly necessary, and the surface is considered. The distance to the casing and the focal length problem; therefore, it is naturally not necessary to form a linear distance and length limitation; in other words, the present invention utilizes the transition of the spatial pattern so that the luminance of the light-emitting diode crystal does not affect the luminance of the light-transmitting diode. In this case, it can create the effect of making full use of space. [Embodiment] The contents, features, and embodiments of the present invention will be described in the following description, and the review of the present invention will be further understood. As shown in the third and fourth figures, the present invention relates to a light-emitting diode light source body, and the light-emitting body (3) of the light-emitting diode mainly comprises: a reflective shell plate (3 1 ) 'the reflective shell The section of the plate (31) is parabolically shaped from the inner 8 I33H09 • outward convex arc (inside the concave arc), and one side of the parabola is adjacent to the inner side of a base plate (30). And the outer side of the base plate (3 〇) is adjacent to a cover (32), the cover (32) may be made of a transparent resin or a material having a transparent property, and the transparent resin contains a fluorescent component; The cover (32) has at least a reflective section (3 2 A ) of a relatively convex arc of the reflective shell, and a light-transmissive section (3 2 B ) connected to the reflective shell, the transparent section (3 2 B) ) forms a turning edge (3 2 C) with the reflective section (3 2 A) (shown as a turning point in the two-dimensional plane). _ The base plate (3 〇) is provided with at least one LED crystal (3 3) (also
二個、三個至更多而形成同一正面發光面向之並列），該發光二極 體晶體（3 3)之正面發光面向，斷面狀態下延伸之假想線（L 1 )通過該反光殼板（3 1);且基座板（3 〇 )於斷面狀態下， 其與罩殼（3 2 )鄰接點（P ) ’與該假想線（L i )平行之假想 延伸線（L 2)亦通過該反光殼板（31)。 又，本發明之反光殼板（31)係外部貼附反光薄膜（3工 A)，或外部浸塗反光薄膜。 ® 請參閱第五圖所示，以二維平面之舉例說明，本發明之光源 體（3)之基座板（3 0)上之發光二極體晶體（3 3)之光線， 由於係「正面發光面向」（即光線主要之散發表面），斷面狀態下 延伸之假想線（L 1)通過該反光殼板（3 1 )，因此主要之光線 技射在反光殼板（3 1 )，而受到反射影響，該光線又循由反光段 (3 2 A)之反射後，由透光段（3 2 B)射出，形成各個平行 之面光源；因此形成發光二極體晶體（3 3)毋庸設於反光段（3 2 A )以及透光段（3 2 b )對應面（可以省略直線距離），卻可 9 1331409 以達到設在透光段（3 2 B)之狀態？ 且由於罩殼（3 2)斷面形成一向反光殼板相對凸弧之反光 & ( 3 2 A)’基於凸面鏡之反光效果形成反射，再經反光殼板以 凹面鏡之聚光反射出罩殼，内側為散光之效果，經由分散光線亦 會反射回反光殼板），整個罩殼（3 2 )均可以形成光線之均勻、 平行之面光源。 惟以上所述者’僅為本發明之較佳實施例，並非因此而拘限 _本發明之專利範圍’舉凡運用本發明專利範圍中所述構造《等效 變化，均應包含於本發明之專利範圍中。 1331409 、 【圖式簡單說明】 第一圖係先前技術（一）之立體圖 第二圖係先前技術（二）之平面圖 第三圖係本發明之立體圖 第四圖係本發明之平面示意圖 第五圖係本發明之光線效果示意圖 【主要元件符號說明】 * ( 10):發光體 (11) :陽極 (12) :陰極 (1 3 ):碟盤 (14):發光二極體晶粒 (1 5):接線 (1 6 ):透鏡 • ( 2 0 ):發光體 (21):本體外殼 (2 2):陰極 (2 3):陽極 (24):發光二極體晶粒 (2 5 ):拋物曲面 (2 6) ·接線 (3 ):發光二極體 11 1331409 (3 0 ):基座板 (3 1 ):反光殼板 (3 2):罩殼 (3 2 A):反光段 (3 2 B ):透光段 (3 2 C ):轉折緣 (3 3 ):發光二極體晶體 (L 1 ):假想線 (L 2 ):假想延伸線 (P ):鄰接點 (3 1 A):反光薄膜Two, three or more, forming a side by side of the same front light-emitting surface, the front side of the light-emitting diode crystal (33) is illuminated, and the imaginary line (L1) extending in the cross-sectional state passes through the reflective shell (3 1); and the base plate (3 〇) in the cross-sectional state, the imaginary extension line (L 2 ) parallel to the imaginary line (L i ) adjacent to the cover (3 2 ) The reflective shell (31) is also passed. Further, the reflective shell plate (31) of the present invention is attached with a reflective film (3 work A) or an external dip coated reflective film. ® As shown in the fifth figure, the light of the light-emitting diode crystal (3 3) on the base plate (30) of the light source body (3) of the present invention is illustrated by a two-dimensional plane. The front side of the light emitting surface (ie, the main emitting surface of the light), the imaginary line (L 1) extending in the cross-sectional state passes through the reflective shell (3 1 ), so the main light is emitted on the reflective shell (3 1 ). Under the influence of reflection, the light is reflected by the reflective section (3 2 A), and then emitted by the transparent section (3 2 B) to form respective parallel surface light sources; thus forming a light-emitting diode crystal (3 3) It is not necessary to set it in the reflective section (3 2 A ) and the corresponding section of the light-transmitting section (3 2 b ) (the straight-line distance can be omitted), but it can be 9 1331409 to reach the state of the light-transmitting section (3 2 B). And because the cover (32) section forms a reflection of the opposite convex arc of the reflective shell, (3 2 A)' reflects on the reflective effect of the convex mirror, and then reflects the cover through the reflective mirror with the concave mirror. The inner side is the effect of astigmatism, which is reflected back to the reflective shell by dispersing light. The entire casing (3 2 ) can form a uniform, parallel surface light source of light.
