201028587 六、發明說明： 【發明所屬之技術領域】 本發明係與照明用燈泡有關，更詳而言之係指一種易 於調整色溫之三波長LED白光照明燈泡結構。 【先前技術】 按，由於發光二極體（Light Emitting Diode，簡稱LED) @ 具有低耗能、高效率的特性及優點，因此目前各國及業界 皆將此一技術列為策略發展的重點技術，以取代現有傳統 之照明設備。 第一圖所示，現有之LED照明燈泡，係將多數可發出 紅光、綠光、藍光LED元件1、2、3電性連接於一電路 板4上，再由該電路板4連接一連接端子（圖中未示），以 由該連接端子與電源（或燈座）電性連接，使能利用三原 色光（紅、綠、藍）混出可供照明用之白光而照射。但此 種利用紅、綠、藍光加以混成白光之方式，除了波長配合 要能配出白色外，光強度亦要有適當的配比，因此在混光 實施上有著相當之困難度，常見白光僅出現在光束交集的 區域中央，遠離中央區域的混光色溫會逐漸趨近紅、綠、 藍二原色光，在照明區域形成色彩繽紛的色塊，為混光不 均所造成之缺失，使照明效果不佳。 請參閱二圖所示，另有一種LED照明燈泡，係將多數 可發出紅光、綠光、藍光LED元件1、2、3電性連接於 4 201028587 • 一電路板4上，再由該電路板4連接一連接端子（圖中未 • 示），並於該電路板4前置設一透明燈罩5，該透明燈罩5 内部則加入螢光粉（劑）6，以利用三原色光（紅、綠、 藍）經由螢光粉之混合而混出可供照明用之白光。但此種 方式所能照明之廣度有限，且因LED元件1、2、3發光 的同時必然伴隨著高熱，而螢光粉6本身並不耐高溫，故 當LED元件溫度提高時，榮光粉會快速產生質變，造成 LED元件產生光衰現象，嚴重影響照度或明亮度。 ❿ 其次，LED的波長取決於磊晶層的結構及組成的材 料，更重要的是晶格匹配的課題，導致半導體因溫度的高 低致生波長飄移的問題不容忽視。就開機初期和通電一段 時間來說，開機初期隨著紅光發光效率的強度，該RGB三 原色光混出白色偏紅的光源；通電一段時間，隨著發光效 率較高的藍光逐步增強’讓混光色溫偏向冷光系的白色偏 藍光，故於兩段時期所混光的色溫各不相同。依光譜的角 ❹度來看，波長由暖色系移動到冷色系的熱飄移範圍過大， 嚴重影響混光色溫的白平衡，相對減損光源的照度。 另外，亦有/種利用一發白光之LED充當主要光源， 並於白光LED附近置設一組由紅、綠、藍光等LED構成 之色溫補償單元’即當白光LED亮度因螢光層質變而快速 下降而形成光衰時，以紅、綠、藍光LED隨著衰變的白光 LED進行單顆或多顆之電流強度調整。但此種方式不僅無 法精確地恢復至原先白光之標準色溫，且欲精準地控制單 5 201028587 顆或多顆之電流強度，於實際上有著相當高之難度而不符 經濟效益。 【發明内容】 有鑑於此，本發明之主要目的乃在提供一種易於調整 色溫之三波長LED白光照明燈泡結構，係能減少混光不均 .之情形，使照明效果較佳。 本發明之另一主要目的乃在提供一種易於調整色溫之 ❹二波長LED白光照明燈泡結構，係可將色溫於冷色系白光 至暖色系白光間加以調整者。 本發明之再一主要目的乃在提供一種易於調整色溫之 二波長LED白光照明燈泡結構，係可形成高演色性之三波 長白光者。 緣此，本發明乃提供一種易於調整色溫之三波長LED 白光照明燈泡結構，包含有：一承載基板；至少三紅光LED ❹封裝元件，係設置並電性連接於該承載基板上，具有一可 發出紅光之LED晶片、一罩覆於該紅光LED晶片上之罩 覆體及多數佈設於該罩覆體中之擴散粒子；至少三綠光 LED封裝元件，係設置並電性連接於該承載基板上，具有 -可發㈣光之LED晶片、-罩覆於朗光㈣晶片上 之罩覆體及多數佈設於該罩覆體中之擴散粒子；至少三藍 光LED封裝元件，係設置並電性連接於該承載基板上，具 有-可發出藍光之LED W、-罩覆於該藍光LED晶片 201028587 -上之罩覆體及多數佈設於該罩覆體中之擴散粒子；一罩型 •燈殼，係連接於該承載基板之周緣；一導電件，係連接於 該罩型燈殼上’並與該承載基板電性連接，用以將外部之 電源導入至該承載基板上。 【實施方式】 為使貴審查委員能對本發明之特徵與特點有更進一 步之了解與認同，茲列舉以下較佳實施例並配合圖式說明 ❹如下： 請參閱第三及第四圖，係本發明第一較佳實施例所提 供一種易於調整色溫之三波長LED白光照明燈泡結構1 〇 0，包含有一承載基板1 〇、多數紅光LED封裝元件2 〇、 多數綠光LED封裝元件3 〇、多數藍光LED封裝元件4 〇、一罩型燈殼5 0及一導電件6 0 :其中： 請參閱第三圖’該承載基板1 〇，為一呈圓形板狀之 φ 印刷電路板（PCB )’佈設有多數預定態樣之電路佈線（圖 中末示）。 請參閱第三圖及第四圖，該紅光LED封裝元件2 〇， 包含有一紅光LED晶片2 1、一罩覆體2 2及多數之擴散 粒子2 3 ;該紅光LED晶片2 1係能接通預定電流而發射 出紅光，該罩覆體2 2係由透光之材質所製成，如環氧樹 脂（Epoxy)、矽膠（Silicone)、玻璃…等透光材質，該罩 覆體2 2係覆蓋於該紅光LED晶片2 1上，該等擴散粒子 201028587 • 2 3係散佈於該罩覆體2 2中，該擴散粒子2 3係由且* ‘反射率或高散射率之材料所製成，例如銀（Silver)、樹^ 石夕（SUicon )或其它材質。該等紅光咖封裝元件2 〇係 依預定態樣佈設於該承載基板！ 〇上，並與該承載基板工 0電性接通’以由該承載基板1 〇供給該等紅光LED封裝 元件2 0電流，以使該紅光LED晶片2 U發射出紅光。 請參㈣三®，鶴光LED封裝元件3 Q，與該紅光 LED封裝元件2 〇相同具有一綠光LED晶片（圖中未示）、 •-罩覆體3 2及多數擴散粒子3 3 ;惟該綠光led封裝元 件3 0與該紅光LED封裝元件2 0之差異僅在於所發出之 光色不同而已，即紅光LED封裝元件2 〇係發出紅光，而 綠光LED封裝元件3 0則發出綠光，並同樣設於該承載基 板1 0上，並與該承載基板1 〇電性接通。 請參閱第三圖，該藍光LED封裝元件4 0，與該紅光 LED封裝元件2 〇相同具有一藍光LEd晶片（圖中未示）、 ⑩一罩覆體4 2及多數擴散粒子4 3 ;惟該藍光led封裝元 件4 0與該紅光LED封裝元件2 〇之差異僅在於所發出之 光色不同而已，即紅光LED封裝元件2 〇係發出紅光，而 藍光LED封裝元件4 〇則發出藍光，並同樣設於該承載基 板1 0上，並與該承載基板1 〇電性接通。 請參閱第三圖，該罩型燈殼5 0係由不透光之材質所 製成’係罩設於該承載基板1 〇之周緣上，並位於該紅、 綠、藍光LED封裝元件2 〇、3 〇、4 0非發光方向之位 8 201028587 -置上，用以支撐並同時保護該承載基板工〇。 請參閱第三圖，該導電件6 〇，具有-方型殼體6 i 及二導電端子6 2，該方型殼體6丄係連接於該罩型燈殼 50上，域方型殼體61係由絕緣材質所製成，該二導 電端子6 2係由導電材質所製成，係置於該方型殼體6 i 中，並於該承載基板10電性連接，且該二導電端子U 並局部露出於該㈣殼體61外，_於與外部之燈座（圖 鲁中未示），而由外部之電源由導電端子62導入至該承載基 板10上’再由該承載基板i 0提供該等紅 封裝元件20、3G、4_，使該等紅、綠= 封裝元件20、30、40能發出紅、綠、藍光藍光 是以，上述即為本發明第一較佳實施例所提供易於調整 色溫之三波長1^自絲紐泡結構i Q Q之各部構件及 其組裝方式介紹，接著再將其特點介紹如下： 由於該各紅、綠、藍光led封裝元件2 0、3 〇、4 ⑩〇之罩覆體中皆佈設有呈預定態樣之擴散粒子，且擴散粒 子在罩覆體内之散佈密度及數量、位置並不相同，因此當 紅、綠、藍光LED晶片分別發出紅、綠、藍光時，其光束 經由該擴散粒子較佳之散射路徑而充分混光，以提供較佳 之光線散射路徑，使紅、綠、藍光之光束能近乎完全重疊， 而能均勻地混成白光，並不致有其它顏色之色塊產生，其 未能均勻混合之色塊區域僅會發生於光形之周緣區域，其 所佔之比例遠低於人眼所能見及之比率，以達成均句混光 9 201028587 • 之效果’況且光線經由擴散粒子所發散後，將使照明之廣 - 度更佳。 再者，由於本實施例易於調整色溫之三波長led白光 照明燈泡結構1 〇 〇，係具有多數各色紅、綠、藍光之Led 封裝元件，因化可利用佈設於承載基板上位置之置換或調 配’來達成調整色溫之功效，即使混成之白光能於冷色系 白光至暖色系白光間進行調整’如室内照明或室外照明所 ❹採用不同色溫之白光，以能因應不同之照明需求。藉此， 本發明易於調整色溫之三波長LED白光照明燈泡結構工〇 〇，不僅具有較佳之混光效果，使能均勻地混成白光而無 其它色塊之產生，更具備藉由佈設於承載基板上各色LED 封装元件之數量、設置位置之變化，來達成調整色溫之效 果，並防止產生眩光之情形，而無需習知技術必須改變電 流、電壓之複雜方式，使其調整色溫之方式較為簡易。 請參閱第五圖，係本發明第二較佳實施例所提供一種 ®易於調整色溫之三波長led白光照明燈泡結構2〇〇,其 與第一較佳實施例相同包含有一承栽基板i 〇、多數紅光 led封裝元件2 〇、多數綠光LED封裴元件、多數藍 光LED封裝元件4〇、一罩型燈殼5〇及一導電件6 〇 ·, 惟與第一較佳實施例之主要差異在於： 該易於調整色溫之三波長LED白先照明燈泡結構2〇 =更包含有-圓弧狀之增光片7 〇，該增光片7 〇係由透 、’之材質所製成，如環氧樹脂（Ep〇Xy)、矽膠⑽〇、 201028587 玻璃…等透光材質，係連接於該罩型燈殼5 〇上，並位於 該等紅、綠、藍光封裝元件2 0、3 0、4 0之發光方向 上’使該等紅、綠、藍光封裝元件20、30、40所發 出之光線距離更長，而可加強聚光效果》201028587 VI. Description of the Invention: [Technical Field] The present invention relates to a light bulb for illumination, and more particularly to a three-wavelength LED white light bulb structure that is easy to adjust color temperature. [Prior Art] According to the fact that Light Emitting Diode (LED) @ has low energy consumption and high efficiency, it is now a key technology for strategy development in various countries and industries. To replace the existing traditional lighting equipment. As shown in the first figure, the existing LED lighting bulb electrically connects a plurality of red, green and blue LED elements 1, 2, 3 to a circuit board 4, and then connects the circuit board 4 to a connection. A terminal (not shown) is electrically connected to the power source (or the socket) by the connection terminal, so that the three primary colors of light (red, green, and blue) can be used to illuminate the white light for illumination. However, such a method of mixing white light by using red, green and blue light, in addition to the wavelength matching, can be matched with white, and the light intensity must have an appropriate ratio, so that there is considerable difficulty in the implementation of light mixing, and common white light is only Appearing in the center of the intersection of the beams, the color temperature of the mixed light away from the central area will gradually approach the red, green and blue primary colors, forming a colorful color block in the illumination area, which is caused by the lack of mixed light, making the illumination not effectively. Please refer to the two figures. Another LED lighting bulb is to electrically connect most of the red, green and blue LED components 1, 2 and 3 to 4 201028587 • a circuit board 4, and then the circuit The board 4 is connected to a connecting terminal (not shown), and a transparent lamp cover 5 is disposed in front of the circuit board 4. The inside of the transparent lamp cover 5 is filled with phosphor powder 6 to utilize the three primary colors of light (red, Green, blue) mixed with white light for illumination through the mixing of phosphor powder. However, the breadth of illumination in this way is limited, and the LED elements 1, 2, and 3 are accompanied by high heat, and the phosphor powder 6 itself is not resistant to high temperature, so when the temperature of the LED element is increased, the glory powder will Rapidly produce qualitative changes, causing light decay of LED components, seriously affecting illumination or brightness. ❿ Secondly, the wavelength of the LED depends on the structure and composition of the epitaxial layer. More importantly, the problem of lattice matching leads to the problem that the wavelength drift of the semiconductor due to the high temperature can not be ignored. In the initial stage of power-on and power-on for a period of time, with the intensity of red light-emitting efficiency at the beginning of the boot, the RGB three primary colors of light mix out a white-red light source; after a period of power-on, the blue light with higher luminous efficiency is gradually enhanced. The color temperature is biased toward the white light of the cold light system, so the color temperature of the light mixed in the two periods is different. According to the angle of the spectrum, the range of thermal drift from the warm color to the cool color is too large, which seriously affects the white balance of the mixed color temperature and relatively reduces the illumination of the light source. In addition, there are also a type of white light LED used as the main light source, and a set of color temperature compensation unit composed of red, green, blue light and the like is disposed near the white light LED, that is, when the brightness of the white light LED is changed due to the quality of the fluorescent layer When the light decays rapidly, the red, green, and blue LEDs are adjusted in single or multiple current intensity with the decaying white LED. However, this method can not only accurately restore the original color temperature of the original white light, and it is difficult to control the current intensity of the single 5 201028587 or more, which is actually quite difficult and economical. SUMMARY OF THE INVENTION In view of the above, the main object of the present invention is to provide a three-wavelength LED white light bulb structure that is easy to adjust color temperature, which can reduce the unevenness of light mixing, and the illumination effect is better. Another main object of the present invention is to provide a two-wavelength LED white light bulb structure that is easy to adjust the color temperature, and that can adjust the color temperature between cool white light and warm white light.
