球經工業化後，人們的生活水準雖獲得改善，但是 2而來的較環境污染，而光觸媒技術就在這樣的時空 應運而生。例如，在空氣污染方面，光觸媒材料能 有政=理如氧化氮(Ν0χ)、氧化硫(s0x)等污染物質。此外， 由於光觸媒材料在反應中僅粉演催化角色，本身並不會消 耗掉，又沒有不良副作用，因此成為防治空氣污染的利器。 光觸媒反應係藉由紫外光或陽光照射，使光觸媒材料 表2的電子吸收足夠能量而脫離，而在電子脫離的位置形 成電的電洞，而電洞會將附近水分子游離出的氫氧基 (fH)氧化，亦即電洞會奪取其電子，使其成為活性極大的 氫氧自由基(OH radical);氫氧自由基一旦遇上有機物質便 會將電子奪回，使得有機物質因鍵結潰散而分崩離析。— 般的污染物或病源體多半是碳水化合物，分解後大部分會 變成無害的水及二氧化碳，因此可以達到除污及滅菌的目 的。 為了改善室内空氣品質’於是有人將光觸媒材料應用 於空氣濾淨器，如日本專利案Jp2〇〇3〇93486A中揭示一空 氣濾淨器，其為典型地利用風扇將外界空氣帶入本體，再 由紫外光照射而催化光觸媒材料，使其產生淨化空氣的功 效。然由於空氣濾淨器係獨立設置，因而在使用上有佔空 200950827 間的問題。 亦有人嘗试將光觸媒材料與照明光源結合，期能解決 上述問題。如日本專利案JP2〇〇42〇9359A所揭示，其在照 明光源之燈罩部分塗覆一層光觸媒材料，藉此達成淨化空 氣與節省空間的功效。然由於光觸媒材料之催化反應主要 在其塗覆表面處發生，而僅藉由自然對流之空氣循環則顯 然會導致淨化空氣之效率不彰的問題。 此外，如歐洲專利案EP1870114A1所揭示，有人將光 ❿觸媒材料塗布於吊扇燈具之上，嘗試將吊扇、燈具及光觸 媒材料結合使其兼具室内散熱、照明與淨化空氣的效果， 並利用吊扇之強制對流而增加光觸媒材料淨化空氣之效 率。然而，使用者為因應氣候變化，常僅使用該發明之照 ^力能’並不-併制吊扇，是故無法發揮強制對流的功 效，而使該光觸媒吊扇燈具顯然無法適用於各種使用狀況。 【發明内容】 ❹ j解^述_，本發明之目的為提供_種光觸媒燈 :肉化空氣與節省空間之效，且藉由光觸媒燈 /、内权風扇模組，而使光_材料淨化空氣之效率提升。 為了達成上述目的，本發明提供一 g媒電性基板、多個第-發光二極體二散二 if :ί: 體可發出可見光且其配置於該第-電性 基，上’織ρ電性基板配置於該散熱裝置下方，該躺装置 熱裝置與第—電性基板之中央^具 厂。、一 /同，且兩孔洞之位置相互對應；JL特徵 在於，該綱峨Ht,嗅'_:發= 7 200950827 體及光觸騎料，絲觸㈣是塗布於_ 二發光二極體是配置於該第二電性基板之上，且‘二光= 體可發出紫外光而催化該光觸媒材料。 弟一么先一極 於上述光觸媒燈具之中，該散熱裝置更包栝一 該風散模組配置於散熱裝置之第一孔洞位置。 羽、，’、 赴述光觸媒燈具之巾，該朗騎_如是二氧化 鈦或一氧化鈦與鉑之混合物。 ’該些第二發光二極體所發出 -400nm，較佳波長範圍則介於 於上述光觸媒燈具之中 ❹的备、夕卜光波長範圍介於300 360-390nm。 在上述光觸媒燈具之中， 組或側排風式風扇模組。 該風扇模組為直下式風扇模 性光觸媒燈具之中，第二發光二極體例如是可撓 *板且其是環狀配置於該些散熱片整體的内緣或 =坠散熱片整體的外圍，且第二發光二極體面向該些散埶 片。 ”、 丈在上述光觸媒燈具之中，更包括有一導流保護上蓋，該導 流保ί上蓋之中央為一圓形中空且其配置於散熱裝置之上，此 外弟一電性基板是環狀配置於導流保護上蓋之下表面，且第二 發光二極體面向該些散熱片。 在上述光觸媒燈具之中，該些散熱片是平板型鰭片，且該 些散熱片是以輻射狀、矩陣排列或不規則狀排列而配置於該第一 孔洞外圍。 在上述光觸媒燈具之中，該些散熱片是針狀鰭片，且該些 200950827 散熱片之橫截面為矩形、圓形或橢圓形。 綜上所述，由於本發明的光觸媒燈具為光觸媒材料與 燈具之結合，而非如一般空氣清淨器需獨立設置，因而可 節省空間。再者，由於第二發光二極體可發出紫外光而催 化光觸媒材料，故可分解空氣中的有機物質或病源體。此 外，光觸媒材料是塗布於散熱片之上，而可利用發光二極 體產生的廢熱提高光觸媒材料分解有機物質的反應速率。 另外，藉由風扇模組的強制對流效果，可令光觸媒燈具淨 Φ 化空氣之效率提昇。是故，本發明之光觸媒燈具可兼具室 内照明、淨化空氣及節省空間等功效。 為讓本發明之上述目的、特徵和優點更能明顯易懂， 下文將以實施例並配合所附圖示，作詳細說明如下。 【實施方式】 請參閱圖1，圖1所繪示為本發明之光觸媒燈具之第 一實施例的爆炸圖。該光觸媒燈具1包括有一保護罩10、 一反射環圈組20、一第一電性基板30、多個第一發光二極 ❹ 體40、一散熱裝置50、一第二電性基板60、多個第二發 光二極體70及一上外殼80。該保護罩10配置於第一電性 基板30之下，而第一發光二極體40可發出可見光，且第 一發光二極體40可為點狀配置或以圖1所示之長條狀結構 配置於第一電性基板30之面向保護罩10側。此外，散熱 裝置50配置於第一電性基板30上方，而上外殼80則再配 置於散熱裝置50上方。其中，散熱裝置50包括有一風扇 模組501與多個散熱片502。再者，散熱裝置50、第一電 性基板30及保護罩10之中央分別具有一第一孔洞510、 200950827 第二孔洞310及第三孔洞110,且三孔洞之位置相互對應。 另外，反射環圈组20包括有一外反射環圈201及一内反射 環圈202,其中，外反射環圈201是配置於保護罩10外緣， 内反射環圈202是配置於保護罩10之第三孔洞110内緣， 而反射環圈組20與保護罩10之結合方式例如是藉由壓合 或螺紋旋入之方式固定。此外，第一發光二極體40、散熱 裝置50及上外殼80之間例如是藉由螺絲（未繪示）或其他 鎖固元件而固定連結。 φ 接著，請同時參考圖1及圖2，圖2所繪示為尚未安 裝上外殼之光觸媒燈具之第一實施例的組合圖。在光觸媒 燈具1中，風扇模組501是配置於散熱裝置50之中央第一 孔洞510位置，且該些散熱片502是以輻射狀配置於風扇 模組501外圍。此外，光觸媒燈具1更可包括多個功率積 體電路90，該些功率積體電路90配置於散熱片502之外 緣，而每一功率積體電路90與兩相臨之功率積體電路90 等距相隔，且功率積體電路90係藉由導線或其他連接器 (Connector，未繪示）與第一電性基板30及第二電性基板60 ® 電性連接。再者，由於第一發光二極體40及第二發光二極 體70之電性相同，因而可共用電源，亦即第一發光二極體 40及第二發光二極體70皆分別藉由第一電性基板30及第 二電性基板60而與功率積體電路90電性連接。此外，第 二電性基板60為一可撓性印刷電路板而環狀配置於該些 散熱片502整體之外圍，而第二發光二極體70配置於第二 電性基板60上而面向該些散熱片502,且第二發光二極體 70可發出紫外光。另外，該些散熱片502上塗布有光觸媒 材料。換言之，光觸媒材料可藉由第二發光二極體70所發 200950827 =紫外光而催化分解空氣中的有機物質，達到淨化空氣 剂鍵Ϊ圖2所示，在本實施例中，該些散熱片地是知 型籍片，並以輻射狀配置於風扇模組5〇1外圍，^反 具有通常知識者亦可如圖2a所示以另一輕射狀排=域 該錄熱片502 ’或如圖2b所示而以矩陣排列配置= 熱片502 ’抑或如圖2c所示而採不規則排列配置該 片50士。另外’本領域具有通常知識者也可依需求而二, ❹2戶示改用針狀鰭片之散熱片5〇2並配置於風扇模組501 外圍。再者，本發明之散熱裝置5〇之外觀並不限於圓形， 本領域具有通常知識者亦可改用直他幾何形狀，例如圖 2e-2g所示之矩形外觀或圖办所示>之不規則外觀。 再者’凊參考圖3，圖3所綠示為尚未安裝上外殼之 光觸媒燈具之第二實施例的級合圖。第二實施例與第〆實 施例之構件與配置方式有雷同之處，於此不再資述。不同 的地方在於，在第二實施例之光觸媒燈具2中，第二電性 ❹ίΞΓ是環狀配置於風扇模級5gi側邊與該些散熱片502 整體的内緣之間，而第二發光二 二電性基 板且面向該些散熱片502。因此，塗^散熱片502 上ίϊΐ材枓可被第二發光二植體70,發出之紫外光催 化而/▲氣中的有機物質，連到淨化空氣之效。 目請^考圖4,圖4所繪示為尚未安裝上外殼之光觸媒 燈具之第二實施例的組合圖。第三實施例斑[實施例之 構件與配置方式有雷同之處，於此不述第不同的地方 在於，在第三實施例中，光觸媒燈呈3更包括-導流保護 11 200950827 上蓋100,該導流保護上蓋100之中央為一圓形中* 1〇 圖5所示），且其位於風扇模組501之上。接著，^ ί二4 H5所繪示為第三實施例之第二電性基板 配置，H第二電性紐6G，，是環狀配置於該導流保 護上盍100之下表面，且第二發光二極體70，，配置於第二 ❹After the industrialization of the ball, people's living standards have improved, but the environmental pollution caused by the 2, and the photocatalyst technology came into being in such a time and space. For example, in terms of air pollution, photocatalyst materials can have pollutants such as nitrogen oxides (NOx) and sulfur oxides (s0x). In addition, since the photocatalyst material only plays a catalytic role in the reaction, it does not consume itself and has no adverse side effects, and thus becomes a weapon for preventing air pollution. The photocatalytic reaction is caused by ultraviolet light or sunlight, so that the electrons in the photocatalyst material 2 absorb enough energy to separate, and the electric holes are formed at the position where the electrons are separated, and the holes will release the hydroxyl groups from the nearby water molecules. (fH) oxidation, that is, the hole will capture its electrons, making it an extremely active hydroxyl radical; OH radicals will recapture electrons once they encounter organic matter, causing organic matter to bond Collapsed and fell apart. Most of the pollutants or pathogens are carbohydrates, and most of them will become harmless water and carbon dioxide after decomposition, so the purpose of decontamination and sterilization can be achieved. In order to improve the indoor air quality, a photocatalyst material is applied to an air filter. For example, an air filter is disclosed in Japanese Patent Application No. Jp. No. 3,394, 864, which typically uses a fan to bring outside air into the body. The photocatalytic material is catalyzed by ultraviolet light to produce an effect of purifying the air. However, since the air filter is independently installed, there is a problem in the use of duty 200950827. Some people have tried to combine the photocatalyst material with the illumination source to solve the above problems. As disclosed in Japanese Patent Laid-Open No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. However, since the catalytic reaction of the photocatalytic material occurs mainly at the surface of the coating, the circulation of air by natural convection alone may cause a problem of inefficiency in purifying the air. In addition, as disclosed in European Patent No. EP1870114A1, a photocatalyst material is coated on a ceiling fan lamp, and an attempt is made to combine the ceiling fan, the lamp and the photocatalyst material to combine the effects of indoor heat dissipation, illumination and air purification, and use the ceiling fan. The forced convection increases the efficiency of the photocatalyst material to purify the air. However, in order to cope with climate change, the user often uses only the invention of the invention, and does not manufacture the ceiling fan, so that the effect of forced convection cannot be exerted, and the photocatalyst ceiling fan lamp is obviously not applicable to various use conditions. SUMMARY OF THE INVENTION The purpose of the present invention is to provide a photocatalyst lamp: flesh-forming air and space-saving effect, and photo-material cleaning by means of a photocatalyst lamp/, an internal fan module.
