201038870 六、發明說明： 【發明所屬之技術領域】 ，尤係關於 本發明係涉及一種半導體照明裝置 一種發光二極體燈具。 【先前技術】 :們由:長期過度倚賴石化燃料，除造成能源 紐缺及石油價格高漲而牽鮮經濟發展，更使全球二 〇 氧化碳與有害氣體的排放濃度日益增加，導致地球 暖化所引起的氣候反常、生態環境的破壞、以及對 ^貞生存的危害日益顯現，為永續經營人類賴以生 存的地球生態環境，必須同時解決能源危機與環境 巧染問題’開發新能源及再线源是推展if約能源 及南效率使用能源最重要的策略，而傳統照明所消 耗的能源極為可觀，發展照明節能將是最重要的新 能源科技，而半導體照明採用高功率高亮度的發光 〇 體(LED)為光源，該新光源以其高發光效率、節 能、長壽、環保（不含汞）、啟動快、指向性、耐衝 擊耐震動等優點，具有廣泛取代傳統照明光源的 潛力。 惟’ LED由於將輸入電能的〜90%轉變成為 熱量，只有10%〜20%轉化為光能，且由於[ED晶片 面積小發熱密度高，因此發展LED照明的關鍵必須 先解決散熱問題；優良的LED燈散熱系統可在同等 201038870 ，入功率下得到較低的工作溫度，延長LED的使用 壽命，或在同樣的溫度限制範圍内，增加輸入功率 或晶片密度，從而增加LED燈的亮度；結點溫度 (Jimcuon temperature)是衡量LED燈散熱性能的重 要技術指標，由於散熱不良導致的結點溫度升高， 將嚴重影響到發光波長、光強、光效和使用壽命。 應用高功率高亮度LED在照明的新光源上，必 須配合高效率的散熱機構以盡量降低L E D的結點溫 度，才能發揮上述諸多優點，否則照明裝置的發光 冗度、使用哥命將大打折扣，影響所及將使該照明 裝置的節能效果不彰，並直接衝擊該照明裝置的可 靠度’引發嚴重的光衰甚至使照明裝置失效。 應用尚功率高亮度LED在照明的新光源上，必 須使照明燈具的配光具有符合傳統燈具的配光能 力，以避免LED照明燈具的應用受到限制，基於led 光源的出光具有一定角度的指向性及高亮度的點光 源特性’在照明節能及在需要聚光的應用上（如投射 燈、車頭燈、手電筒、隧道燈、探照燈等）具有先天 的優勢’但也由於所述指向性及集中過亮的點光源 特性’直視時會呈現過亮刺眼的發光點，在照明的 視野中易造成亮度分佈或亮度範圍存在極端的對 比，以致降低觀察細部或目標的視覺能力並易引起 不舒適感’稱為眩光（glare)，長時間在這種照明條 5 201038870 件下工作，除會使影像模糊化，閱讀吃力，容易造 成眼睛疲勞，降低閱讀效率，甚至造成眼睛酸痛， 視力明顯下降及頭痛的問題，更可能會產生厭煩、 躁急不安等情緒及心理與生理的病症，因此不恰當 地使用光源和燈具或光環境會造成令人不舒適而形 成眩光污染。 習知LED燈具已見有採用與傳統燈具搭配的反 〇 光罩進行配光，唯由於傳統燈具的光源係無指向性 地沿其周圍均勻漫射，反光罩可使投射在不需要照 明的光線反射到需要照明的範圍而增加光源的照明 效率；反之，以LED燈具直接採用與傳統燈具搭配 的反光罩進行配光，仍然會因所述LED光源的指向 性及點光源或光源集中的特性，照度只會集中在一 相對較小的區域，並隨範圍的擴大而快速暗淡，無 法達到通用照明（general lighting)燈光隨擴散距離 〇 呈現逐漸減弱的均勻配光要求，雖然上述配光可以 藉由導光罩的透鏡特性達到一定程度的改善，但光 效的耗損及嚴重的眩光問題仍然無法獲得解決；因 此，要將LED光源廣泛應用在通用照明上，除高散 熱效率需求外，對如何均勻配光、降低光損及防止 或降低眩光已成為LED照明燈具業者必須設法解決 的重要課題。 ' 【發明内容】 201038870 有鑑於此，有必要提供一種兼具高散熱效率、 靈活多元的照明配光並降低眩光之照明裝置。 一種發光一極體燈具，包括一燈殼、一光學部、 一電氣部及一散熱部。該燈殼為一中空的殼體；該 光學部設於該燈殼之前端，包括複數發光二極體光 源、一反射罩及一具有配光功能的導光罩；該電氣 部設於燈殼内並位於燈殼之後端，包括一電路板， 〇

該發光二極體燈具100中，發光二極體光源21 所産生的熱量藉由安裝座34吸收，並由導熱體33 傳到散熱器32之實心體321及鰭片322，藉由鰭片 322之間與外界的氣流溫差導致的密度差所形成的 熱浮力，使進入鰭片322之間的冷空氣吸收由發光 15 201038870 二極體光源21傳至鰭片322的熱量而升溫並上浮， 再藉由熱空氣向上漂浮的慣性趨勢使鰭片322外的 冷空氣自氣窗113進入鰭片322之間的流阻降低； 與此同時，新的冷空氣會自動填補該已上浮的熱空 氣空間，並同樣經吸熱升溫上浮而發揮鰭片322局 部散熱的效果；該上浮的較熱氣流除部分由鰭片322 周邊的氣窗113排出，其餘部分繼續順利流經隔板 42所設氣孔421進入電氣部40，並由後殼體12之 壁面所設氣孔123排出，來持續導引較低溫冷卻氣 流進入鰭片322之間，從而在該發光二極體燈具100

Description of the invention: [Technical field to which the invention pertains], in particular, the present invention relates to a semiconductor lighting device, a light-emitting diode lamp. [Prior Art]: From: long-term excessive dependence on fossil fuels, in addition to causing energy shortages and high oil prices, leading to economic development, and increasing the concentration of global carbon dioxide and harmful gases, leading to global warming The resulting climate anomalies, the destruction of the ecological environment, and the harm to the survival of the cockroach are increasingly manifested. To sustain the operation of the earth's ecological environment on which human beings depend, it is necessary to solve the problem of energy crisis and environmental pollution at the same time. 'Developing new energy and re-sources It is the most important strategy for promoting energy use and energy efficiency. The energy consumed by traditional lighting is extremely impressive. The development of lighting energy saving will be the most important new energy technology, while semiconductor lighting uses high-power and high-brightness illuminating bodies ( LED) is a light source. With its high luminous efficiency, energy saving, longevity, environmental protection (without mercury), fast start-up, directivity, impact resistance and vibration resistance, the new light source has the potential to widely replace traditional illumination sources. However, because LED converts ~90% of input energy into heat, only 10%~20% is converted into light energy, and because [ED wafer area is small, the heat density is high, so the key to developing LED lighting must first solve the heat dissipation problem; The LED lamp cooling system can achieve lower operating temperature, increase the service life of the LED, or increase the input power or wafer density within the same temperature limit, thereby increasing the brightness of the LED lamp. The point temperature (Jimcuon temperature) is an important technical indicator for measuring the heat dissipation performance of LED lamps. The increase in junction temperature due to poor heat dissipation will seriously affect the wavelength, intensity, efficacy and service life of the LED. The application of high-power high-brightness LEDs in the new light source of illumination must be combined with a high-efficiency heat-dissipating mechanism to minimize the junction temperature of the LEDs in order to exert the above-mentioned advantages. Otherwise, the illumination redundancy and the use of the lighting device will be greatly reduced. The impact will make the lighting device less energy-efficient, and directly impact the reliability of the lighting device' causing severe light decay or even invalidating the lighting device. The application of high-brightness LEDs in the new light source of illumination must make the light distribution of the lighting fixtures conform to the light distribution capability of the traditional lamps, so as to avoid the limitation of the application of the LED lighting fixtures, and the light output based on the led light source has a certain angle of directivity. And high-brightness point source characteristics 'has innate advantages in lighting energy saving and in applications that need to collect light (such as projection lamps, headlights, flashlights, tunnel lights, searchlights, etc.) but also because of the directivity and concentration The bright point light source characteristics will show excessively bright glare points when looking directly. In the field of illumination, there is an extreme contrast between the brightness distribution or the brightness range, which reduces the visual ability to observe details or targets and easily causes discomfort. It is called glare. It works for a long time under this kind of lighting strip 5 201038870. In addition to blurring the image, reading is difficult, it can cause eye fatigue, reduce reading efficiency, and even cause eye pain, visual loss and headache. Problems, more likely to cause emotional and psychological and physical disorders such as boredom, urgency, and therefore When using a light source and a light fixture or the environment and can cause unpleasant glare pollution formed. Conventional LED lamps have seen the use of a reticle with a traditional luminaire for light distribution, since the light source of the conventional luminaire is uniformly diffused along its circumference without directivity, the reflector can be projected onto the light that does not require illumination. Reflecting to the range of illumination required to increase the illumination efficiency of the light source; conversely, the LED light fixture directly adopts the reflector with the traditional light fixture for light distribution, still due to the directivity of the LED light source and the concentration characteristics of the point light source or the light source. Illumination will only be concentrated in a relatively small area, and will quickly dim with the expansion of the range, unable to achieve the general lighting requirements of the general lighting with the diffusion distance, although the above light distribution can be used The lens characteristics of the light guide cover have been improved to some extent, but the loss of light efficiency and severe glare problems cannot be solved. Therefore, LED light sources should be widely used in general illumination, in addition to high heat dissipation efficiency requirements, how to evenly Light distribution, reducing light loss and preventing or reducing glare have become important lessons that LED lighting manufacturers must try to solve. question.

The intersection of the two adjacent heat absorbing surfaces 343b is provided with a chamfering surface to form a locking surface 344. Each fixing component includes a screw 305 and a locking component 3〇4 sleeved on the screw 3〇5. The screw 305 is locked in the screw hole corresponding to the middle of the locking surface 344, and the two ends of the locking component 3〇4 are pressed against the edge of the heat conducting substrate 211 of the adjacent two LED light sources 21. Each of the light-emitting one-pole light sources 21 is pressed on the both side edges of the guide substrate 2n by the locking members 3〇4 on both sides to be fixed to the heat absorption surface 34.

The fan 35 is disposed at one end of the heat sink 32 facing the electrical portion 40. The front housing 11a is further disposed at one end of the rear housing 12 and is provided with a plurality of openings 115 to serve as an air inlet or exhaust passage when the fan 35 is operated. No air holes for the airflow into the electric portion 40 are provided on the plate 42a. In addition to the natural convection Q of the hot and cold air, the light-emitting diode lamp 10a is directly forced to introduce the cooling airflow to blow the heat sink 32 by the fan 35 disposed at one end of the heat sink 32 near the electric portion 40.
