Description

發光二極體耦光裝置Light-emitting diode coupling device 【0001】【0001】

本新型係有關一種光學裝置,尤指一種發光二極體耦光裝置。The present invention relates to an optical device, and more particularly to a light-emitting diode coupling device.

【0002】【0002】

在科學的領域中,所有的假設、推論都必須藉由顯而易見的證據來加以證明,在醫療的領域亦同,醫生在判斷病因時,往往須經過多項檢測評估才能確定,但對於體腔內的疾病,體外的檢測如血液、尿液篩檢,卻只能顯示間接數據供醫生在判斷病因時參考,若要進一步明確的確定病因,仍須進行直接的視診,因此,針對人體內部觀察檢測的醫療用內視鏡就此問世。In the field of science, all hypotheses and inferences must be proved by obvious evidence. In the field of medical treatment, doctors often have to undergo multiple tests to determine the cause, but for diseases in the body cavity. In vitro tests such as blood and urine screening can only display indirect data for the doctor to refer to when determining the cause. If the cause is to be further clearly defined, direct visual inspection is still required. Therefore, medical treatment for internal human observation and detection is required. This is the case with an endoscope.

【0003】[0003]

醫療用內視鏡,早在十九世紀初期愛迪生發明電燈後不久就出現了,但因為燈泡體積之問題,直到二十世紀初期才真正發明出利用小型燈泡做為體內光源的內視鏡,達到體內照明的目的。Medical endoscopes appeared shortly after Edison invented the electric lights in the early 19th century, but because of the volume of the bulbs, it was not until the early twentieth century that the endoscopes that used small bulbs as the light source in the body were actually invented. The purpose of in vivo lighting.

【0004】[0004]

然而,人體的臟器並沒有皮膚及脂肪保護,容易因外界的溫度或是碰撞衝擊而產生病變或損傷,而傳統的氙氣燈在發光時,通常會伴隨著高溫,因此若以傳統的氙氣燈作為醫療用內視鏡的光源使用,很容易因其所產生的高溫對人體產生不必要的傷害。However, the organs of the human body are not protected by skin and fat, and it is easy to cause lesions or damage due to external temperature or collision impact. However, when the conventional xenon lamp is illuminated, it is usually accompanied by high temperature, so if the conventional xenon lamp is used As a light source for medical endoscopes, it is easy to cause unnecessary damage to the human body due to the high temperature generated.

【0005】[0005]

再者,以氙氣燈作為內視鏡光源,僅可見到有如白色日光光源的影像,不容易發現早期腫瘤的微細血管變化。由於癌症生長牽涉血管新生,使用不同波長的光源,如為藍光可在最淺處,顯現出紅色的微血管,綠色則顯示較深層的血管,如此便能利用特殊短波長的光源發現異常血管新生及黏膜變化,提早現形;傳統使用氙氣燈作為光源的內視鏡,係在氙氣燈光源處設置一濾光器,藉由濾光後形成不同波長的光源。Furthermore, with the xenon lamp as the source of the endoscope, only the image of the white daylight source can be seen, and it is not easy to find the microvascular changes of the early tumor. Since cancer growth involves angiogenesis, light sources of different wavelengths are used, such as blue light, which can display red microvessels at the shallowest point, and green, showing deeper blood vessels, so that abnormal angiogenesis can be found using a special short-wavelength light source. Mucosal changes, early appearance; traditional endoscopes using xenon lamps as the light source, a filter is arranged at the source of the xenon lamp, and the light sources of different wavelengths are formed by filtering.

【0006】[0006]

近來,醫療用內視鏡逐漸捨棄傳統氙氣燈,而改以發光二極體等冷光光源作為光源,不僅提升光源的壽命,且具有冷光、高照度、特定色溫等特點,進而解決高溫對人體之臟器所帶來的影響。Recently, medical endoscopes have gradually abandoned traditional xenon lamps, and instead used cold light sources such as light-emitting diodes as light sources, which not only enhance the life of the light source, but also have the characteristics of cold light, high illumination, and specific color temperature, thereby solving the problem of high temperature on the human body. The impact of the organ.

【0007】【0007】

醫療用內視鏡為避免光源在人體內使用時,因為熱而對人體內部造成影響,因此是將光源模組置於外部,再藉由光纖傳導系統將光引導致人體內,因此如何將發光二極體光源的出光以高效率光學裝置耦合入光纖中,成為現今最重要的問題之一。Medical endoscopes prevent the light source from being used in the human body, because of the heat, which affects the interior of the human body. Therefore, the light source module is placed outside, and then the light is led to the human body through the optical fiber conduction system, so how to emit light The light exiting the diode source is coupled into the fiber with high efficiency optics, making it one of the most important issues today.

【0008】[0008]

為了提高光纖的收光能力,一般常用拋物面收光器(Compound Parabolic Concentrator, CPC)之設計方式,此類的設計雖能收集來自發光二極體所有角度的光,但是當發光二極體的發光面積大於或等於光纖的面積時,一般的CPC結構就會出現漏光情形,造成出光效率的下降。In order to improve the light-receiving ability of the optical fiber, a design method of a Compound Parabolic Concentrator (CPC) is generally used. Although such a design can collect light from all angles of the light-emitting diode, when the light-emitting diode emits light, When the area is larger than or equal to the area of the optical fiber, the general CPC structure will leak light, resulting in a decrease in light extraction efficiency.

【0009】【0009】

本新型之主要目的,在於提供一種具有高出光效率的耦光裝置。The main object of the present invention is to provide a light coupling device having high light extraction efficiency.
