Description
本發明是關於一種手術燈，特別是一種以LED作為光源之手術燈。 The present invention relates to a surgical light, and more particularly to a surgical light using an LED as a light source.
請參查台灣專利申請第087119103號「手術燈之無影反射鏡結構」，一種手術燈頭具有一前燈殼及一後燈殼，於前燈殼在後燈殼反向有一大圓形開口以供光線射出，此開口處上方接有比開口更大的圓形面狀之前玻璃，呈倒碗狀之反射鏡之開口下緣固定於距前玻璃上方一小段距離處，前玻璃中心為圓形空心狀，於其中心開口邊緣下接有一握把之盤狀部；前玻璃之上表中心接有一燈座，燈座與握把反向，其上接有燈泡及備用燈泡；在燈泡及備用燈泡之週圍設有筒狀之吸熱玻璃，其高度涵蓋燈座之最上緣直至接近反射鏡之內面頂端以保證由燈泡或備用燈泡所發出之光線一會通過吸熱玻璃後才到達反射鏡。反射鏡之頂端有一圓形開口大約與筒狀之吸熱玻璃的內徑相當以利於將熱幅射至鋁合金製成之後燈殼並靠其廣大之面積對手術燈頭外部散射。反射鏡將接收到之光線由前玻璃射出並聚焦至約距前玻璃中心前方一公尺附近形成一圓柱形之照明範圍。 Please refer to Taiwan Patent Application No. 087119103, "Shadowless Mirror Structure of Surgical Lamp", a surgical lamp head having a front lamp housing and a rear lamp housing, wherein the front lamp housing has a large circular opening in the reverse direction of the rear lamp housing. For the light to be emitted, the front surface of the opening is connected with a circular surface which is larger than the opening. The lower edge of the opening of the inverted bowl mirror is fixed at a small distance from the front glass, and the center of the front glass is round. Hollow-shaped, a disc-shaped portion of the grip is attached to the edge of the central opening; a lamp holder is connected to the center of the front glass; the lamp holder is opposite to the grip, and the bulb and the spare bulb are connected thereto; A cylindrical heat absorbing glass is arranged around the bulb, the height of which covers the uppermost edge of the lamp holder until it approaches the top surface of the mirror to ensure that the light emitted by the bulb or the spare bulb passes through the heat absorbing glass before reaching the mirror. A circular opening at the top end of the mirror is approximately equivalent to the inner diameter of the cylindrical heat absorbing glass to facilitate the scattering of heat to the outer side of the surgical lamp head after the aluminum alloy is made of the lamp housing. The mirror emits the received light from the front glass and focuses it about one meter in front of the center of the front glass to form a cylindrical illumination range.
習知之該手術燈頭是以鹵素燈泡作為光源，由於鹵素燈泡的發光角度相較於LED光源的發光角度大，因此，習知之該手術燈頭的該反射鏡的深 度較深，以有效利用鹵素燈泡的照光，但由於鹵素燈泡的光電轉換效率較低，在鹵素燈泡於發光的同時，會散發大量的熱，因此，該手術燈頭設置有該吸熱玻璃以吸收鹵素燈泡所散發之熱，並於該反射鏡的頂端設置有圓形開口以將熱散出，而犧牲部分鹵素燈泡之照光，且由於鹵素燈泡所產生的能量，大多是以熱的形式釋出，因此，習知之手術燈頭相當耗電。 The surgical lamp head is a halogen light bulb as a light source. Since the illumination angle of the halogen bulb is larger than the illumination angle of the LED light source, the depth of the mirror of the surgical lamp head is conventionally known. The degree is deeper to effectively utilize the illumination of the halogen bulb, but since the halogen bulb has low photoelectric conversion efficiency, a large amount of heat is emitted while the halogen bulb emits light, and therefore, the surgical lamp head is provided with the heat absorbing glass to absorb the halogen. The heat emitted by the bulb, and a circular opening is provided at the top end of the mirror to dissipate the heat, and the illumination of the partial halogen bulb is sacrificed, and the energy generated by the halogen bulb is mostly released in the form of heat. Therefore, conventional surgical heads consume considerable power.
LED的光電轉換效率較鹵素燈泡為佳，因此以LED取代鹵素燈泡可降低該手術燈頭之耗電，但一般LED的發光角度介於120度至130度之間，無法以單一個LED取代鹵素燈泡，需以複數個LED模擬鹵素燈泡的全周光作為習知手術燈頭的光源，但若將習知手術燈頭之鹵素燈泡以複數個LED取代，則會形成如附件1之光斑形狀，這是由於LED的發光角度小且發光指向性強，因此，經由該反射罩反射之光斑會產生許多亮點，無法呈現均勻的圓形光斑，而呈現不規則形狀之光斑，且光斑之均勻度相當低，無法符合手術燈之國際法規的規範。 The photoelectric conversion efficiency of LED is better than that of halogen bulb. Therefore, replacing the halogen bulb with LED can reduce the power consumption of the surgical lamp head. However, the illumination angle of LED is generally between 120 degrees and 130 degrees. It is impossible to replace the halogen bulb with a single LED. The full-circumference light of a plurality of LED analog halogen bulbs is required as a light source of a conventional surgical lamp head. However, if a halogen bulb of a conventional surgical lamp head is replaced by a plurality of LEDs, a spot shape such as Annex 1 is formed, which is due to The LED has a small illumination angle and strong illuminance directivity. Therefore, the spot reflected by the reflector will generate many bright spots, and it will not be able to present a uniform circular spot, but will exhibit an irregular shape of the spot, and the uniformity of the spot is relatively low. Meets the specifications of international regulations for surgical lights.
本發明的主要目的是藉由反光罩將LED光源的照光均勻反射，以於1000mm距離外的一區域上形成直徑為19cm之高均勻度(high uniformity)且無影度(shadowless)之圓形光斑，且單一組LED光源及反光罩的光照強度可達13000lux，因此僅需8組LED光源及反光罩即可達到手術燈之國際法規所規定之100000lux的需求，可有效減低手術燈所需之耗電量。 The main object of the present invention is to uniformly reflect the illumination of the LED light source by the reflector to form a high uniformity and shadowless circular spot with a diameter of 19 cm on an area other than 1000 mm. The illumination intensity of a single group of LED light sources and reflectors can reach 13,000 lux, so only 8 sets of LED light sources and reflectors are needed to meet the requirements of 100,000 lux required by the international regulations of surgical lamps, which can effectively reduce the consumption of surgical lamps.
