Description
本發明是有關於一種照明裝置,且特別是有關於一種發光二極體照明裝置。The present invention relates to a lighting device, and more particularly to a lighting diode lighting device.
目前發光二極體照明裝置產生白光的方式大多是利用一較短波長的發光二極體去激發較長波長螢光粉,進而藉混光的方式達成白光。舉例,藉藍光發光二極體去激發綠光及紅光螢光粉而產生綠光及紅光,進而將藍光、綠光及紅光混光成白光。At present, the way in which the light-emitting diode illumination device generates white light is mostly to use a shorter-wavelength light-emitting diode to excite a longer-wavelength phosphor powder, thereby achieving white light by means of mixed light. For example, the blue light emitting diode is used to excite the green light and the red light fluorescent powder to generate green light and red light, and then the blue light, the green light and the red light are mixed into white light.
然而,習知藉藍光發光二極體去激發綠光及紅光螢光粉時,一般係將綠光及紅光螢光粉混合在一起,用藍光發光二極體去激發混合的綠光及紅光螢光粉。此種激發方式在藍光發光二極體激發綠光螢光粉後產生綠光,部份綠光卻轉而激發紅光螢光粉,因而造成二次激發造成能量損失(re-absorption loss)。此外,綠光及紅光螢光粉的混合會造成綠光及紅光頻譜重疊,降低演色性。However, when the blue light emitting diode is used to excite the green light and the red light fluorescent powder, the green light and the red light fluorescent powder are generally mixed together, and the blue light emitting diode is used to excite the mixed green light and Red light fluorescent powder. This excitation mode produces green light after the blue light emitting diode excites the green fluorescent powder, and part of the green light turns to excite the red fluorescent powder, thereby causing re-absorption loss caused by the secondary excitation. In addition, the combination of green and red phosphors causes the green and red spectrum to overlap, reducing color rendering.

請參照第1圖,其繪示依照本發明一實施例的一種發光二極體照明裝置的示意圖。發光二極體照明裝置100包含一燈桿102以及一燈具104,燈具104固設於燈桿102的頂端上。燈具104包含一燈罩105以及一發光單元106。燈罩105包覆於發光單元106外。燈具104亦可具有一散熱結構108,其連接至發光單元106,藉以使發光單元106運作產生的熱能加速散去。Please refer to FIG. 1 , which is a schematic diagram of a light emitting diode illumination device according to an embodiment of the invention. The LED lighting device 100 includes a light pole 102 and a light fixture 104 fixed to the top end of the light pole 102. The light fixture 104 includes a light cover 105 and a light emitting unit 106. The lamp cover 105 is wrapped around the light emitting unit 106. The luminaire 104 can also have a heat dissipation structure 108 that is coupled to the illuminating unit 106 so that the thermal energy generated by the operation of the illuminating unit 106 is accelerated.
請參照第2圖,其繪示依照本發明一實施例的螢光粉單元所組成區域之最大寬度的原理示意圖。為了避免多色螢光粉混合在一起所造成的二次激發能量損失,本發明採用多色螢光粉分離的設計。然而,多色螢光粉分離的設計在近距離的狀況下,人眼能夠區分各種顏色螢光粉所產生的光。因此,相鄰各種顏色螢光粉單元所組成區域之最大寬度P需小於特定的距離。根據經濟部的「路燈設計規定」,如第1圖的燈桿102的標準高度H為8公尺,因此 燈具104距離照射面之距離會等於或大於8公尺。當被觀測物的大小被投射成小於一個弧分(六十分之一度)的視角時,將無法被人眼所分辨。換言之,第2圖中的最短距離Dmin 應為8公尺,第2圖中的夾角θ應為1/60度。若根據第2圖中的公式即可求出最大寬度P為2328微米。當相鄰各種顏色螢光粉單元所組成區域的之長或寬的最大寬度小於2328微米時,才能不被人眼區分出不同螢光粉單元的顏色。Please refer to FIG. 2, which is a schematic diagram showing the maximum width of a region composed of a phosphor powder unit according to an embodiment of the invention. In order to avoid the secondary excitation energy loss caused by the mixing of the multi-color phosphors, the present invention adopts a design of multicolor phosphor powder separation. However, the design of multi-color phosphor powder separation allows the human eye to distinguish the light produced by the phosphors of various colors in close proximity. Therefore, the maximum width P of the area composed of adjacent phosphor powder units needs to be smaller than a specific distance. According to the "Street Light Design Regulations" of the Ministry of Economic Affairs, the standard height H of the light pole 102 as shown in Fig. 1 is 8 meters, so the distance of the light fixture 104 from the illuminated surface is equal to or greater than 8 meters. When the size of the observed object is projected to a viewing angle smaller than one arc (one-sixth of a degree), it will not be distinguishable by the human eye. In other words, the shortest distance D min in Fig. 2 should be 8 meters, and the angle θ in Fig. 2 should be 1/60 degrees. According to the formula in Fig. 2, the maximum width P can be found to be 2328 μm. When the maximum width of the length or width of the area formed by the adjacent phosphor powder units is less than 2328 microns, the color of the different phosphor units can be distinguished from the human eye.
