本发明是有关一种发光二极管总成，特别是有关于一种用以取代日光灯管的发光二极管灯管总成。The invention relates to a light-emitting diode assembly, in particular to a light-emitting diode lamp assembly used to replace fluorescent tubes.
背景技术Background technique
照明对于人类的生活影响是相当显著的，尤其是自爱迪生发明电灯泡之后，不论是白天或是黑夜都需要照明提供人类日常生或所需。目前的照明，主要有钨丝灯泡，日光灯管，以及省电灯泡。省电灯泡主要是取代传统的钨丝灯泡，提供跟钨丝灯泡相同亮度与使用习惯，而日光灯管，目前大量的使用在办公室或是公共区域等大面积的照明。The impact of lighting on human life is quite significant, especially since Edison invented the light bulb, no matter it is day or night, lighting is needed to provide human daily life or needs. Current lighting mainly includes tungsten filament bulbs, fluorescent tubes, and energy-saving bulbs. Energy-saving light bulbs mainly replace traditional tungsten light bulbs, providing the same brightness and usage habits as tungsten light bulbs, while fluorescent tubes are currently widely used in large-area lighting such as offices or public areas.
目前，在节能减碳与追求无汞等的环保议题下，发光二极管刚好同时符合上述两种的要求。并且，发光二极管是属于固态照明，并不需要像传统的日光灯管一样会有易碎的玻璃等组件，这对于照明组件来说，货物运送的方便性可以大幅提高。另外，发光二极管具有体积小与光源的指向性高等的优点，因此比较容易设计在体积较小的照明或是需要指向性的光源。所以，将发光二极管应用在传统的日光灯管的照明，就成为下一代照明的考虑与主流。At present, under the environmental protection issues of energy saving and carbon reduction and the pursuit of mercury-free, light-emitting diodes just meet the above two requirements at the same time. Moreover, light-emitting diodes belong to solid-state lighting, and do not require components such as fragile glass like traditional fluorescent tubes. For lighting components, the convenience of cargo transportation can be greatly improved. In addition, light-emitting diodes have the advantages of small size and high directivity of the light source, so it is relatively easy to design lighting in a small size or a light source that requires directivity. Therefore, the application of light-emitting diodes in traditional fluorescent tube lighting has become the consideration and mainstream of next-generation lighting.
请参阅图1，显示一种整合发光二极管的照明总成，其中多个发光二极管20位于壳体10的内部，并且使用一灯罩16遮住壳体10的出光面。目前，主流的发光二极管照明总成皆是如此设计。图1可以想象成一个灯管的侧面剖面的结构示意图。Please refer to FIG. 1 , which shows a lighting assembly integrating LEDs, wherein a plurality of LEDs 20 are located inside the casing 10 , and a lampshade 16 is used to cover the light emitting surface of the casing 10 . At present, mainstream LED lighting assemblies are designed in this way. Fig. 1 can be imagined as a structural schematic diagram of a side section of a lamp tube.
然而，真正的灯管，其截面是曲面，所以在设计上会跟图1示有稍许的不同。请参阅图2，显示管状发光二极管照明总成的截面结构示意图，其中多个发光二极管20位于半管状的壳体12内部，并且有一对应的半管状的透明灯罩18与壳体结合成一管状。通常会在壳体12里面设计一个平板，可以让多个发光二极管20安装在其上。However, the section of the real lamp tube is a curved surface, so the design will be slightly different from that shown in Figure 1. Please refer to FIG. 2 , which shows a schematic cross-sectional structural view of the tubular LED lighting assembly, wherein a plurality of LEDs 20 are located inside the semi-tubular casing 12 , and a corresponding semi-tubular transparent lampshade 18 is combined with the casing to form a tube. Usually, a flat plate is designed inside the casing 12 on which multiple light emitting diodes 20 can be installed.
发光二极管的优点，应用在照明上，有时优点同时会是缺点，其中一个就是发光二极管的尺寸过小，单位面积可以发射的光线过强，在应用到照明的时候会产生眩光。为了降低眩光，一种方式是使用雾面遮罩将各自独立的发光二极管的光线均匀化，但是，这会造成输出光的衰减。但是，发光二极管的发光效益，每年都会随着制程的改善而持续的增加亮度，这会造成使用雾面灯罩来均匀化光线的困难度。甚至，为了尽可能的均匀化发光二极管的光线，使用雾面效果更重的灯罩，这样更会降低光的输出。The advantages of light-emitting diodes are applied to lighting, and sometimes the advantages are also disadvantages. One of them is that the size of light-emitting diodes is too small, and the light that can be emitted per unit area is too strong, which will cause glare when applied to lighting. One way to reduce glare is to use a matte mask to even out the light from individual LEDs, however, this will result in attenuation of the output light. However, the luminous efficiency of LEDs will continue to increase in brightness every year with the improvement of the manufacturing process, which will make it difficult to use a fog lampshade to even out the light. Even, in order to homogenize the light of the LED as much as possible, use a lampshade with a heavier matte effect, which will reduce the light output.

鉴于上述的发明背景中，为了符合产业利益的需求以及达到上述的目的，本发明提出一种发光二极管总成，其包括一凹面反射体，一位于该凹面反射体中央区域的支撑具，以及多个发光二极管。上述的支撑具有一第一平面与一第二平面，在该第一平面与该第二平面之间具有一夹角。上述的多个发光二极管分别位于该第一平面与该第二平面上，光线从该多个发光二极管发射的后经由该凹面反射体反射后由一输出面出去。In view of the above-mentioned background of the invention, in order to meet the needs of industrial interests and achieve the above-mentioned purpose, the present invention proposes a light-emitting diode assembly, which includes a concave reflector, a support located in the central area of the concave reflector, and multiple light emitting diodes.

The above-mentioned multiple light emitting diodes are respectively located on the first plane and the second plane, and the light emitted from the multiple light emitting diodes is reflected by the concave reflector and goes out through an output surface.

具体实施方式Detailed ways
本发明在此所探讨的方向为一种发光二极管照明总成。为了能彻底地了解本发明，将在下列的描述中提出详尽的步骤及其组成。显然地，本发明的施行并未限定于发光二极管照明的技艺者所熟悉的特殊细节。另一方面，众所周知的组成或步骤并未描述于细节中，以避免造成本发明不必要的限制。本发明的较佳实施例会详细描述如下，然而除了这些详细描述的外，本发明还可以广泛地施行在其他的实施例中，且本发明的范围不受限定，其以之后的专利范围为准。The direction of the present invention discussed here is an LED lighting assembly. In order to provide a thorough understanding of the present invention, detailed steps and components thereof will be set forth in the following description. Obviously, the practice of the invention is not limited to specific details familiar to those skilled in LED lighting. On the other hand, well-known components or steps have not been described in detail so as not to unnecessarily limit the invention. The preferred embodiments of the present invention will be described in detail as follows, but in addition to these detailed descriptions, the present invention can also be widely implemented in other embodiments, and the scope of the present invention is not limited, and it is subject to the following patent scope .
本发明使用反射式的方式输出发光二极管的光线，并非直接将发光二极管的光线直接射出，可以避免炫光的产生。同时，使用反射式的原理，透过选定的材质可以将反射后的光线更均匀化的输出，这时灯罩可以采用透明式或是雾面效果较淡的灯罩，可以避免因使用较重的雾面灯罩而降低光线的输出。The present invention outputs the light of the light-emitting diode in a reflective manner, instead of directly emitting the light of the light-emitting diode, so that the generation of glare can be avoided. At the same time, using the reflective principle, the reflected light can be output more uniformly through the selected material. At this time, the lampshade can be transparent or the lampshade with a light matte effect, which can avoid the use of heavy lampshades. Foggy shade reduces light output.
请参阅图3，显示本发明的发光二极管照明总成的截面结构示意图，其中壳体100凹面的反射体，位于凹面的中央区域有一个支撑110。支撑110的结构，具有两个平面，两个平面之间具有一个夹角，而多个发光二极管120分别位于支撑110的这两个平面上。一般，会将发光二极管焊接在一印刷电路板上，然后再将印刷电路板固定在支撑110上。多个发光二极管120所发射出的光线，经过壳体100的反射之后，向下方的输出面射出。多个发光二极管120的色光，可以是全白光发光二极管，不论是冷色的正白光或是暖色系的白光，或是使用不同色光的发光二极管进行，也可以进行混光，一切依使用者的需要安装不同的发光二极管。在图3中，一灯罩130与壳体100组成后成为一柱状的灯管，其中灯罩130可以是透明或是带有一点的雾面效果。Please refer to FIG. 3 , which shows a schematic cross-sectional structure of the LED lighting assembly of the present invention, wherein the reflector of the concave surface of the housing 100 has a support 110 located in the central area of the concave surface. The structure of the support 110 has two planes with an angle between the two planes, and a plurality of LEDs 120 are located on the two planes of the support 110 respectively. Generally, the LEDs are soldered on a printed circuit board, and then the printed circuit board is fixed on the support 110 . The light emitted by the plurality of light emitting diodes 120 is reflected by the casing 100 and then emitted to the output surface below. The color light of multiple light emitting diodes 120 can be all white light emitting diodes, whether it is positive white light of cool color or white light of warm color, or light emitting diodes of different colors can be used, or mixed light can be performed, all according to the needs of users Install different LEDs. In FIG. 3 , a lampshade 130 is formed with the housing 100 to form a cylindrical lamp tube, wherein the lampshade 130 can be transparent or have a little fog effect.
壳体100的材料可以是金属铝，其内部可以加上反射片，或是使用塑料，其内部加上反射片等。不论是金属铝或是塑料，都可以使用压出成型的方式形成，例如铝挤型壳体或是压出件的塑料等。另外，支撑110的材质可以跟壳体100相同，并且是一体成型。而灯罩130的材料，通常会使用透明的塑料，例如聚甲基丙烯酸甲酯(PMMA)、压克力(Acrylic)、聚乙烯(PE)、或是聚碳酸酯(PC)；并且灯罩的形成方式也可使用压出成型。在壳体100与灯罩130的接和处，可以设计一些微小的结构，增进两者之间的的固定效果。同时，也可以设计扣件的方式将壳体100与灯罩130之间固定。The material of the casing 100 can be aluminum, and reflective sheets can be added inside, or plastic can be used, and reflective sheets can be added inside. Whether it is metal aluminum or plastic, it can be formed by extrusion molding, such as aluminum extruded shell or plastic of the extruded part. In addition, the material of the support 110 can be the same as that of the casing 100, and it is integrally formed. And the material of lampshade 130 usually uses transparent plastics, such as polymethyl methacrylate (PMMA), acrylic (Acrylic), polyethylene (PE), or polycarbonate (PC); and the formation of lampshade The method can also use extrusion molding. At the junction of the housing 100 and the lampshade 130, some tiny structures can be designed to improve the fixing effect between the two. At the same time, fasteners can also be designed to fix the housing 100 and the lampshade 130 .
对于某些应用当中，不只是考虑到灯具正下方的照明，同时也为了增加发光二极管照明灯具在侧面角度的照明，如图4所示，可以设计成将壳体102的弧角或是弧度降低，例如减少为120度。这种方式可以增加发光二极管照明的侧向光源。相较于先前技术中所示的结构，即使将壳体102的弧角减少，由于发光二极管的指向性，也很难增加侧向光源。但是，由于本发明使用反射式的设计，想要增加侧向的光源可以更容易的实施。For some applications, not only to consider the lighting directly under the lamp, but also to increase the lighting of the LED lighting lamp at the side angle, as shown in Figure 4, it can be designed to reduce the arc angle or arc of the housing 102 , for example reduced to 120 degrees. This way can increase the side light source of LED lighting. Compared with the structure shown in the prior art, even if the arc angle of the casing 102 is reduced, it is difficult to increase the side light source due to the directivity of the LED. However, since the present invention uses a reflective design, adding a side light source can be implemented more easily.
如果，侧向的光源的强度不需要太强，可以在壳体102与灯罩132之间设计雾面遮罩140，降低侧面的光输出，如图5所示。这种结构，特别适用在像是办公室内的照明，使用几个灯管组合成一个灯盘，提供平面的光源。这样的实施方式，不只是灯具的正下方得到光源，在灯具非正下方的部份也可以获得照明。If the intensity of the side light source does not need to be too strong, a fog cover 140 can be designed between the casing 102 and the lampshade 132 to reduce the side light output, as shown in FIG. 5 . This structure is especially suitable for lighting in offices, where several light tubes are combined into a light panel to provide a flat light source. In such an embodiment, not only the light source can be obtained directly under the lamp, but also the part not directly below the lamp can be illuminated.
请参阅图6，将壳体104设计成具有180度的弧角，这时，主要的光线都会往正下方射出。在这种设计中，灯罩134通常会采用雾面灯罩，避免正下方的光线会产生炫光。Please refer to FIG. 6 , the housing 104 is designed to have an arc angle of 180 degrees, at this time, the main light will be emitted directly downward. In this design, the lampshade 134 usually adopts a matte lampshade to avoid glare caused by the light directly below.
另外，影响本发明的一个重要的因素，就是支撑110与壳体开口之间的距离h。这个距离h愈长，支撑110本身会阻挡较多的光线；这个距离h愈短，虽然比较不会阻挡光线，但是发光二极管120的光线比较不容易被反射。In addition, an important factor affecting the present invention is the distance h between the support 110 and the housing opening. The longer the distance h is, the more light will be blocked by the support 110 itself; the shorter the distance h, although the light will not be blocked, the light from the LED 120 will be less likely to be reflected.
请参阅图7，当使用者并不需要一个完整的灯管的时候，灯罩150也可以设计成平面。一般，平面的灯罩150的制作成本通常会较低。另外，在产品的运送上也比较不占空间，也可以降低运送成本。Please refer to FIG. 7 , when the user does not need a complete lamp tube, the lampshade 150 can also be designed as a plane. Generally, the manufacturing cost of the planar lampshade 150 is generally lower. In addition, it takes up less space in the transportation of products, and can also reduce transportation costs.
请参阅图8，壳体106也可以设计成其他的曲面，例如椭圆形或是抛物面。抛物面的特点是，当发光二极管120接进抛物面的焦点时，整个灯具可以提供近似接近平行的光线输出。这对于特殊光型有需求的应用，可以符合其要求。一般传统的灯管的光源，相较于采用阴极射线激发汞蒸气得到白光，所以只会有各向均匀四散的光型，不可能提供单一方向直下式的平行光束。设计成不同的曲面，会让灯具有不同的光型，主要是由应用面决定。另外，请参阅图9，壳体108也可以设计成多边形，而不限定于曲面，例如有五个边或是八个边。Please refer to FIG. 8 , the housing 106 can also be designed as other curved surfaces, such as an ellipse or a paraboloid. The characteristic of the paraboloid is that when the light emitting diode 120 is connected to the focal point of the paraboloid, the entire lamp can provide approximately parallel light output. This can meet the requirements for applications that require special light types. Generally, the light source of traditional lamps, compared with the cathode ray to excite mercury vapor to obtain white light, will only have a uniformly scattered light pattern in all directions, and it is impossible to provide a single-direction direct parallel beam. Designing different curved surfaces will make the lamp have different light patterns, which are mainly determined by the application surface. In addition, please refer to FIG. 9 , the housing 108 can also be designed as a polygon, not limited to a curved surface, for example, with five sides or eight sides.
在以上图8与图9的实施例当中，可以将壳体截面的内部设计成预订的曲面或是多边形，但是壳体截面的外面仍然是半圆形，这样仍然可以设计使用半圆形的灯罩。In the above embodiments of Figure 8 and Figure 9, the interior of the shell section can be designed as a predetermined curved surface or polygon, but the outside of the shell section is still semicircular, so it is still possible to design and use a semicircular lampshade .
请参阅图10，分别显示不同的支撑的结构。在上述图3到图9之间各实施例的支撑110，主要是设计为V型结构，如图10A所示。这种支撑结构110形状较简单，并且可以有较轻的重量。支撑的另一种设计是Y型的结构112，如图10B图所示。另外，支撑设计成V型结构的时候，可以将V形的内部填满成为三角形，如图10C图显示。不论是哪一种设计，支撑的结构都会由两个平面所夹的角度θ，这个角度θ对于本发明的影响相当重要。当夹角θ较大的时候，发光二极管大部分所发射的光线会往壳体的中央区域照射，反射的结果会有较多的直下式光线，整个灯具的光型会有较高的指向性；当夹角θ较小的时候，发光二极管大部分所发射的光线会往壳体的两端区域照射，反射的结果会有较多的侧光，整个灯具的光型会有较低的指向性。另外，Y形的支撑，除了夹角θ，还可以有一个参数，就是可以调整发光二极管的位置。一种极端的例子，如图11所示，发光二极管120的位置通过Y形支撑112的设计已经接近壳体100的圆心。Please refer to Fig. 10, which shows different supporting structures respectively. The supports 110 in the above-mentioned embodiments between FIG. 3 and FIG. 9 are mainly designed as V-shaped structures, as shown in FIG. 10A . This support structure 110 is simpler in shape and can be lighter in weight. Another design of the support is a Y-shaped structure 112, as shown in Figure 10B. In addition, when the support is designed as a V-shaped structure, the interior of the V-shape can be filled to form a triangle, as shown in Figure 10C. Regardless of the design, the supported structure will have an angle θ between two planes, and this angle θ is very important to the present invention. When the included angle θ is large, most of the light emitted by the LED will irradiate the central area of the housing, and the result of reflection will be more direct light, and the light pattern of the entire lamp will have higher directivity ; When the included angle θ is small, most of the light emitted by the LED will irradiate the two ends of the housing, and the result of reflection will be more side light, and the light pattern of the entire lamp will have a lower direction sex. In addition, the Y-shaped support, in addition to the included angle θ, can also have a parameter, that is, the position of the light-emitting diode can be adjusted. As an extreme example, as shown in FIG. 11 , the position of the light emitting diode 120 is already close to the center of the housing 100 through the design of the Y-shaped support 112 .
请参考图3，灯罩130上也可以形成一层荧光粉层，与发光二极管120产生混光。例如黄色的荧光粉层与蓝色的发光二极管混光，产生白色的照明光源。黄色荧光粉可以是钇铝石榴石(YAG)或是钽铝石榴石(TAG)或是硅酸盐，等。另外，也可以使用多种色光的荧光粉搭配不同的色光的发光二极管。例如，使用蓝光发光二极管，但是使用包含绿光，红光等多波长的荧光粉，或是使用紫外光发光二极管搭配三圆色的荧光粉混成白光。不同色光的荧光粉，可以使用氮化物，硫化物，或是硅酸盐等进行调配。Please refer to FIG. 3 , a phosphor layer may also be formed on the lampshade 130 to generate mixed light with the LED 120 . For example, the yellow phosphor layer mixes with the blue light-emitting diode to produce a white lighting source. The yellow phosphor can be yttrium aluminum garnet (YAG) or tantalum aluminum garnet (TAG) or silicate, etc. In addition, phosphor powders of various colors can also be used to match light-emitting diodes of different colors. For example, use blue light-emitting diodes, but use phosphors with multiple wavelengths such as green light and red light, or use ultraviolet light-emitting diodes with three-color phosphors to mix white light. Phosphor powders of different shades can be formulated using nitrides, sulfides, or silicates.
在本发明中，由于使用一次性反射进行发光二极管的光线均匀化，相较于使用穿透式的雾面灯罩，可以避免较大的光损失，因此较有机会提供较均匀的高亮度照明。由于支撑结构至少有两个平面，之间的夹角可以决定灯具的光型有较多的正向光或是侧光。另外，当支撑设计成Y形结构，还可以调整发光二极管的位置，会有更多的条件决定灯具的光型。而壳体的反射面，可以是圆形，抛物面，近似抛物面，椭圆，或是其他的曲面，或者是多边型。不同形状的壳体对于灯具的光型会有决定性的影响。In the present invention, since the one-time reflection is used to homogenize the light of the LED, compared with the use of the penetrating fog lampshade, greater light loss can be avoided, so there is a greater chance to provide more uniform high-brightness illumination. Since the support structure has at least two planes, the angle between them can determine whether the light pattern of the lamp has more front light or side light. In addition, when the support is designed as a Y-shaped structure, the position of the LED can also be adjusted, and there will be more conditions to determine the light pattern of the lamp. The reflective surface of the housing can be a circle, a paraboloid, an approximate paraboloid, an ellipse, or other curved surfaces, or a polygon. Housings of different shapes will have a decisive influence on the light pattern of the lamp.
显然地，依照上面实施例中的描述，本发明可能有许多的修正与差异。因此需要在其附加的权利要求项的范围内加以理解，除了上述详细的描述外，本发明还可以广泛地在其他的实施例中施行。上述仅为本发明的较佳实施例而已，并非用以限定本发明的申请专利范围；凡其它未脱离本发明所揭示的精神下所完成的等效改变或修饰，均应包含在下述申请专利范围内。Obviously, according to the description in the above embodiments, the present invention may have many modifications and differences. It is therefore to be understood, within the scope of the appended claims, that the invention may be practiced broadly in other embodiments than the foregoing detailed description. The above are only preferred embodiments of the present invention, and are not intended to limit the scope of the patent application of the present invention; all other equivalent changes or modifications that do not deviate from the spirit disclosed in the present invention should be included in the following patent applications within range.
