技术领域 Technical field
本发明涉及发光二极管照明装置， 特别涉及照明高度均匀的发光二极管（LED)照明 装置。 背景技术  The present invention relates to a light emitting diode lighting device, and more particularly to a light emitting diode (LED) lighting device having a highly uniform illumination. Background technique
一般的， 圆形光形照明装置不外乎采用圆形发光源再加上透镜， 使圆形光源直接对透 镜成像。 这种设计最为简单， 是传统的常用技术。  In general, a circular light illumination device uses a circular illumination source plus a lens to allow the circular light source to directly image the lens. This design is the simplest and is a common technique commonly used.
请参阅图 1， 图 1是传统的发光二极管照明装置的立体分解图。 大部分发光二极管的 发光源 50釆用圆形发光二极管芯片 51，发光源 50设置在由铝质材料制成的散热板 52上； 发光源 50还设有具有保护作用的塑料壳 53及透明树脂 54。 采用这种圆形发光源 50， 经 过透镜 60成像后， 会看到圆形发光源 50的成像， 但由于整体均匀性不好， 得不到清楚的 光形。  Please refer to FIG. 1. FIG. 1 is an exploded perspective view of a conventional LED lighting device. The light source 50 of most of the light emitting diodes is a circular light emitting diode chip 51, and the light source 50 is disposed on a heat sink 52 made of an aluminum material; the light source 50 is further provided with a protective plastic shell 53 and a transparent resin. 54. With such a circular illumination source 50, after imaging by the lens 60, imaging of the circular illumination source 50 is seen, but due to poor overall uniformity, a clear light shape is not obtained.
请参阅图 2、 3， 图 2、 3是传统的发光二极管照明装置的光线追迹与光形显像图。 由 于传统的发光源 50与透镜 60之间不设置任何对光线进行整光与反光处理的部件，光线朝 向四面八方散射， 难以集中通过透镜 60， 因此， 出光效率低于百分之十。  Please refer to Figure 2, 3, Figure 2, 3 is the light trace and light image of the traditional LED lighting device. Since the conventional light source 50 and the lens 60 are not provided with any components for finishing and reflecting light, the light is scattered in all directions, and it is difficult to concentrate through the lens 60. Therefore, the light extraction efficiency is less than ten percent.
同时， 传统的发光源 50与透镜 60之间距离固定， 不能根据发光源 50与被照射物之 间的距离， 进行焦距的调整， 因此光形无法产生聚焦的效果， 难以提髙原来非常低的出光 效率。 发明内容  At the same time, the distance between the conventional illumination source 50 and the lens 60 is fixed, and the focal length cannot be adjusted according to the distance between the illumination source 50 and the object to be illuminated. Therefore, the light shape cannot produce a focusing effect, and it is difficult to improve the original very low Light extraction efficiency. Summary of the invention

If a full-mask with a tapered surface or a paraboloid is used, the light-emitting efficiency is at most 30% to 40%. If a full-mask with an elliptical surface is used, the light-emitting efficiency can be as high as 70%. Eighty percent; at the same time, the light shape is more uniform, The center point illumination can be doubled to twice the size of other shapes.
本发明中， 在整光罩上再配设具有直筒面、抛物面、 圆锥面中任意一种的反射罩， 可 以提高发光源的出光效率。还可以根据发光源与被照射物之间的距离，调节透镜的聚焦点， 使光形产生聚焦的效果。 附图说明  In the present invention, a reflector having any one of a straight surface, a paraboloid surface, and a conical surface is disposed on the entire mask to improve the light extraction efficiency of the light source. It is also possible to adjust the focus point of the lens according to the distance between the light source and the object to be illuminated, so that the light shape produces a focusing effect.

Figure. As shown in the figure, a light-emitting diode illumination device with uniform illumination, wherein the light source 10 is disposed on a heat dissipation plate 12 made of an aluminum material, the light source 10 is provided with an LED chip 11, and has a protective effect. The plastic case 13 and the transparent resin 14. The light-emitting diode chip 11 emits blue light; the transparent resin 14 is coated with a yellow phosphor, and after the blue light passes through the yellow phosphor, it becomes white light; The entire mask 20 is placed on the light source 10, and the mask 20 is a flat mask having any one of a tapered surface 21, a paraboloid 22, and an elliptical surface 23.
透镜 30设置在发光源 10与整光罩 20的前方位置处。该透镜 30为一凸透镜， 可以将 发光源 10发出且经过整光罩 20整光后的光线集中朝同一方向投射出去。可以根据发光源 10与被照射物之间的距离调节透镜 30的焦距， 使光形产生聚焦的效果。  The lens 30 is disposed at a position in front of the light source 10 and the entire mask 20. The lens 30 is a convex lens, and the light emitted from the light source 10 and concentrated by the whole mask 20 can be concentrated and projected in the same direction. The focal length of the lens 30 can be adjusted according to the distance between the illumination source 10 and the object to be illuminated, so that the light shape produces a focusing effect.
请参阅图 13至图 17, 图 13至图 17是本发明中在整光罩上加装具有直筒面、 抛物面 或圆锥面的任意一种的反射罩的平面示意图。 其中：  Referring to Fig. 13 through Fig. 17, Fig. 13 through Fig. 17 are plan views showing a reflector having any one of a straight surface, a paraboloid or a conical surface attached to the entire hood in the present invention. among them:
反射罩 40罩设在上述整光罩 30上，该反射罩 40为具有直筒面 41、抛物面 42和圆锥 面 43中的任意一种的反射罩。发光源 10发射出来的光线， 经过整光罩 20的椭圆面 23整 光后， 再经过反射罩 40的圆锥面 43反光， 使得发光源 10发出的光形从原来的高斯分布 转化成均匀的分布。 之后再通过透镜 30将光投射出去， 形成月亮形状， 此时具有百分之 七十至百分之八十的出光效率。  The reflector 40 is disposed on the entire mask 30, and the reflector 40 is a reflector having any one of a straight surface 41, a paraboloid 42 and a conical surface 43. The light emitted by the light source 10 is dimmed by the elliptical surface 23 of the whole mask 20, and then reflected by the conical surface 43 of the reflector 40, so that the light shape emitted by the light source 10 is converted from the original Gaussian distribution into a uniform distribution. . The light is then projected through the lens 30 to form a moon shape, which has a light output efficiency of 70% to 80%.
请参阅图 18至图 32， 图 18至图 32是本发明向前与向后调节透镜焦距的平面与光线 追迹图。当光线照射在被照射物的光形变得磨糊不清时， 可以尝试向前或向后调节发光源 10与透镜 30之间的焦距。一般焦距增长时，光形缩小，亮度变亮（如图 24至图 31所示）， 焦距缩短时， 光形放大， 亮度变暗（如图 32所示） ， 光形有聚焦的效果。  Referring to Figures 18 through 32, Figures 18 through 32 are plane and ray tracing diagrams for adjusting the focal length of the lens forward and backward according to the present invention. When the light illuminates the light shape of the object to be irradiated, it is possible to adjust the focal length between the light source 10 and the lens 30 forward or backward. Generally, when the focal length is increased, the light shape is reduced and the brightness is brightened (as shown in Fig. 24 to Fig. 31). When the focal length is shortened, the light shape is enlarged, and the brightness is darkened (as shown in Fig. 32), and the light shape has a focusing effect.
本发明所提供的照明髙度均匀的发光二极管照明装置，经过实际制做以及反复操作测 试之后， 证实的确可以实现预期的功能效益， 同时又是目前市场上看不到的新产品， 具有 产业上的利用价值。  The LED illumination device with uniform illumination uniformity provided by the invention proves that the expected functional benefits can be achieved after actual production and repeated operation tests, and at the same time, it is a new product that is not currently available on the market, and has an industry.
