M418252 五、新型說明： 【新型所屬之技術領域】 本創作係關於一種照明裝置，特別關於一種可部份 點、滅光源之照明裝置。 【先前技術】 近年來隨著發光元件之技術之精進與多樣化，照明裝 置中作為發光元件者已從比較耗電之發光元件（例如鎢絲 燈）轉換成LED或是CCFL等較為省電之發光元件。至今， LED或CCFL等發光元件係被廣泛的應用作為背光源或是 照明光源。就LED與CCFL而言，其元件成本以及發光特 性等係各有其優缺點，因此在照明市場上，雖然LED已經 被廣泛使用，但因發光原理與特性不同，因此CCFL尚有 其應用上之價值。 再者，CCFL與LED在照明上的應用比較特殊的是其 係均可配合可調光之控制迴路之使用，而使其被應用於可 調光之照明裝置。就CCFL而言，最常利用的調光技術就 是叢訊號（burst mode )控制來達到調整CCFL發光元件 之發光量。而就LED而言，最常見的就是利用電流控制迴 路來達到調整LED發光元件之發光量，亦有利用叢訊號 (burst mode)控制來調整LED發光元件之發光量。 承上所述，當發光元件為複數時，不管是利用叢訊號 控制迴路來控制CCFL之發光量，或是利用電流控制迴路 來控制LED發光量，但兩者均有一共同特點，就是複數發 M418252 光元件中之各發光元件係被同時調光，簡而言之，就是當 發光元件為複數時，若要使照明裝置變暗，則照明裝置中 之每一發光元件係同時以一定比例被調暗。 然而，就叢訊號控制迴路或是電流控制迴路而言，其 雖然均為穩定成熟之控制技術，但在控制技術上以及產品 開發成本上均有其一定的複雜度以及一定的成本。 例如圖1所示係為一習知之照明裝置1，該照明裝置 1係主要包含一燈管本體11、複數CCFL發光元件12、一 驅動電路13以及複數電極單元14。如圖所示，若欲使該 等CCFL發光元件12係可以被調光，則必須藉由於驅動電 路13上增加叢訊號控制迴路方可達成，但此時，該等CCFL 發光元件12係同時被調暗或同時被調亮。 综上所述，如何提供一種以更簡單、更低成本之控制 迴路以達到具有實質的調光功能的照明裝置，實為重要課 題之一。 【新型内容】 有鑑於上述課題，本創作之目的為提供一種更簡單、 更低成本之控制迴路以達到具有實質的調光功能的可控 制之照明裝置。 為達上述目的，依據本創作之可控制之照明裝置，其 與一外部電源配合使用，包含一照明裝置本體；設置於照 明裝置本體之複數發光元件；設置於該照明裝置本體中， 且與該等複數發光元件電性連接之一驅動電路；以及設置 5 M418252 於該照明裝置本體中，而與該驅動電路電性連接之一點滅 控制電路，藉由該外部電源之開、關而使該驅動電路部分 驅動或全部驅動該等發光元件，俾使該等發光元件部分或 全部點、滅。 在本創作之可控制之照明裝置之一實施例中，因為點 滅控制電路係包含：一偵測該外部電源之啟動觸發的啟動 觸發偵測電路；一依據該啟動觸發偵測電路所偵測之啟動 觸發情況而提供至少一個穩態致能訊號的多穩態電路；以 及一依據該穩態致能訊號來產生至少一致能訊號或電壓 訊號至該驅動電路的多工開關電路。因此，本創作之可控 制之照明裝置係可藉由該外部電源之開、關而使驅動電路 部分驅動或全部驅動該等發光元件，俾使該等發光元件部 分或全部點、滅。 此外，在本創作之一實施例中，因為點滅控制電路係 更包含有一計時重置電路；此時，多穩態電路係具有一預 設穩態，其中，計時重置電路係計算兩次電源啟動之間的 時間長度，當該時間長度較一預設長度為長時，計時重置 電路便重置該多穩態電路使其於次回電源開啟時為該預 設穩態。因此，本創作之可控制之照明裝置係可藉由該外 部電源之開、關而使驅動電路部分驅動或全部驅動該等發 光元件，俾使該等發光元件部分或全部點、滅。 承上所述，因依據本創作之可控制之照明裝置，由於 照明裝置本體中係具有點滅控制電路，因此當本創作之可 控制之照明裝置與一外部電源配合使用時，使用者可以不 M4 丄 8252 用更換或加裝任冑元件或迴路，即使輕易地使本創作之。 =制之照明裝置之發光元件部份關。又由於點滅控制= =電路構成非常便宜，因此，依據本創作之可控制之防 質以更簡單、更低成本之控制迴路而達到具有ί 貝的調光功能。 汽 【實施方式】 以下將參照相關圖式，說明依本創作較佳實施例之〜 攀種可控制之照明裝置。 〜 (第一較佳實施例） 如圖2所示，本創作較佳實施例之可控制之照明裝置 - 2係主要包含一照明裝置本體21、複數發光元件^、二驅 動電路23、複數電極單元24以及一點滅控制電路乃。 該等發光元件22係設置於該照明裝置本體21，於本 實^例中，該照明裝置本體21係可為塑膠製或鋁製之圓 φ 型管本體或矩型管本體或多邊形管狀本體，而該發光元件 22係可為CCFL.燈管或LED發光條。 驅動電路23係設置於該照明裝置本體21中，且與該 等複數發光元件22電性連接；而點滅控制電路25係亦嗖 置於該照明裝置本體21中，而與該驅動電路23電性連 接，其係藉由外部電源之開、關而使該驅動電路23部分 或全部驅動該等發光元件22，俾使該等發光元件22部分 或全部點、滅。 又如圖3至圖4所示，驅動電路23係更可包含一第 7 M418252 一驅動電路231以及一第二驅動電路232，而該第一驅動 電路231係與部分發光元件22電性連接，該第二驅動電 路232係與該部分以外之發光元件22電性連接。此時， 如圖3所示，當該點滅控制電路25係分別與第一驅動電 路231以及第二驅動電路232電性連接時，該點滅控制電 路25係可以據外部電源之啟動次數來分別控制連接於該 第一驅動電路231以及第二驅動電路232之發光元件22 之點、滅。又如圖4所示，當該點滅控制電路25係僅與 該第一驅動電路231電性連接時，則該點滅控制電路25 僅控制該第一驅動電路231，亦即此時該點滅控制電路25 僅使連接於該第一驅動電路231之該部分發光元件22進 行點、滅。在此，要特別說明的是，於本實施列中所謂點、 滅即使指發光元件全亮或全暗。 此外，在硬體結構上，如圖3、圖4所示，驅動電路 23與點滅控制電路25係可同時設置在一電路板上。 複數電極單元24係包含一第一電極單元以及一第二 電極單元，其係分別設置於該照明裝置本體21之一端部 以及另一端部；其中該外部電源係分別經由該第一電極單 元與該第二電極單元而輸入至該點滅控制電路。 照明裝置2更可包含一反射板（圖未顯示），其係設 置於該照明裝置本體21中，其中該等發光元件22係設置 於該反射板之一側，該驅動電路23與該點滅控制電路25 係設置於該反射板之另一侧。 以下，將以圖5A至圖5B來進一步說明點滅控制電路 M418252 25與驅動電路23係如何控制而使該等發光元件22部分或 全部點、滅。 如圖5A所示，點滅控制電路25係包含一啟動觸發偵 測電路251、一多穩態電路252以及一多工開關電路253。 其中，啟動觸發偵測電路251係用以偵測外部電源之啟動 觸發；多穩態電路252係依據外部電源之啟動觸發情況而 提供至少一個穩態致能訊號El〜En ;多工開關電路253係 包含有複數個開關元件（未示於圖中），該等開關元件係 依據該等穩態致能訊號Ei〜En來決定是否開、關，進而 決定是否提供電壓訊號D1〜Dn4致能訊號至驅動電路23。 又，如圖5B所示，多穩態電路252係包含一啟動計 數電路2521以及一解譯電路2522。啟動計數電路2521係 用以計數啟動觸發偵測電路251之啟動次數或啟動間隔時 間；解譯電路2522則是依據啟動次數或啟動間隔時間來 產生該等穩態致能訊號Ei-En。 在此，要特別說明的是，請再參考圖2及圖3所示， 由於本實施例中係具有2個發光元件22，因此，當兩個發 光元件全亮時，多穩態電路252係輸出兩個穩態致能訊號 Ei、E2,而當多穩態電路252係只有一個穩態致能訊號時， 則2個發光元件22之其中一發光元件22則全暗，另一個 發光元件22則全亮。又如圖4所示，當點滅控制電路25 係僅與第一驅動電路231電連接時，此時，點滅控制電路 25之多穩態電路252所輸出之穩態致能訊號係只控制第一 驅動電路231所連接之發光元件22之點、滅。 9 M418252 再者，如圖6A所示，本創作較佳實施例之照明裝置2 之點滅控制電路25係更包含有一計時重置電路254;該計 時重置電路254係分別與外部電源以及多穩態電路252電 性連接。此時，該多穩態電路252係具有一預設穩態，該 計時重置電路254係計算兩次電源啟動之間的時間長度， 當該時間長度較一預設長度為長時，該計時重置電路254 便重置該多穩態電路252使其為該預設穩態。如圖6B所 示，當多穩態電路252係包含啟動計數電路2521以及解 譯電路2522時，則計時重置電路254係分別與外部電源 以及啟動計數電路2521電性連接。 (第二較佳實施例） 以上之較佳實施例係以CCFL發光元件為說明例，以 下係以LED發光條做為發光元件為說明例。要特別說明的 是，由於本實施例中之控制原理大致與前述相同，因此在 此省略其相關說明。 如圖7所示，本創作較佳實施例之可控制之照明裝置 3係主要包含一照明裝置本體31複數發光元件32、一驅 動電路33、複數電極單元34以及一點滅控制電路35。與 第一較佳實施例不同的是，於本實施例中，發光元件32 係為LED發光條，而驅動電路33係為一提供電流之驅動 電路》 綜上所述，因依據本創作之可控制之照明裝置，由於 照明裝置本體21、31中係具有點滅控制電路25、35，因 此當本創作之可控制之照明裝置與一外部電源配合使用 M418252 使用者可以不用更換或加裝任何元件或迴路，即使輕 易地使本創作之可控制之照明裝置之發光元件部份點 滅。又由於點滅控制電格25、％之電路構成非常便宜， 因此，依據本創作之可趣制之照明裝置係可以更簡單、更 低成本之控_路而如u有實f _光功能。 以上所达僅為舉例性，而非為限制性者。任何未脫離 本創作之精神與範嗜，而對其進行之等效修改或= 應包含於後附之申請專利範圍中。 【圖式簡單說明】 圖1為習知照明裴置的剖面示意圖； 剖面==本創作 <較佳實施例之可控制之照明敦置的 制電佳實施㈣動電路與點滅控 圖4為依據本創作之較佳實施例之 制電路之另-電路方塊說明圖； 點滅控 圖5A為依據本劎 〜電路方塊說明圖創作之較佳實施例之點滅控制電略< _ 5B為依據本創作之較施例 另〜電路方塊說明圖； 站滅控制電路之 作之較佳實施例之點滅控制〜 ΐ 6B為依據本創作之較佳實施例 M418252 再一電路方塊說明圖；以及 圖7依據本創作之另一較佳實施例之可控制之照明裝 置的剖面的示意圖。 【主要元件符號說明】 〔習知〕 I :照明裝置 II :燈管本體 12 : CCFL發光元件 13 :驅動電路 14 :電極單元 〔本創作〕 2、3 :照明裝置 23、 33 :驅動電路 24、 34 :電極單元 21、 31 :照明裝置本體 22、 32 :發光元件 231 :第一驅動電路 232 :第二驅動電路 25、 35 :點滅控制電路 251 :啟動觸發偵測電路 252 :多穩態電路 2521 :啟動計數電路 2522 :解譯電路 M418252 253 :多工開關電路 254 :計時重置電路 Di〜Dn :電壓訊號 E!〜En :穩態致能訊號M418252 V. New description: [New technical field] This creation is about a lighting device, especially for a lighting device that can partially and extinguish the light source. [Prior Art] In recent years, with the advancement and diversification of the technology of light-emitting elements, light-emitting elements in lighting devices have been converted from LEDs that consume more power (such as tungsten lamps) into LEDs or CCFLs. Light-emitting element. Up to now, light-emitting elements such as LEDs or CCFLs have been widely used as backlights or illumination sources. In terms of LED and CCFL, its component cost and luminescence characteristics have their own advantages and disadvantages. Therefore, although LEDs have been widely used in the lighting market, CCFL has its application due to its different light-emitting principles and characteristics. value. Moreover, the special application of CCFL and LED in illumination is that it can be used with dimmable control loops, so that it can be applied to dimmable lighting devices. In the case of CCFL, the most commonly used dimming technique is the burst mode control to adjust the amount of illumination of the CCFL illuminating element. In the case of LEDs, the most common is to use the current control loop to adjust the amount of light emitted by the LED light-emitting elements. The burst mode control is also used to adjust the amount of light emitted by the LED light-emitting elements. As mentioned above, when the illuminating element is plural, whether the plex signal control loop is used to control the illuminating amount of the CCFL or the current control loop is used to control the illuminating amount of the LED, both have a common feature, that is, the plurality of M418252 Each of the light-emitting elements is simultaneously dimmed. In short, when the light-emitting elements are plural, if the illumination device is to be darkened, each of the illumination elements is simultaneously adjusted in a certain proportion. dark. However, in terms of the clump signal control loop or the current control loop, although they are all stable and mature control technologies, they have certain complexity and certain cost in control technology and product development cost. For example, the lighting device 1 of the prior art is shown in Fig. 1. The lighting device 1 mainly comprises a lamp body 11, a plurality of CCFL light-emitting elements 12, a driving circuit 13, and a plurality of electrode units 14. As shown in the figure, if the CCFL light-emitting elements 12 are to be dimmed, it must be achieved by adding a cluster signal control circuit to the driving circuit 13, but at this time, the CCFL light-emitting elements 12 are simultaneously Dim or dim at the same time. In summary, how to provide a lighting device with a simpler and lower cost control loop to achieve a substantial dimming function is one of the important topics.

Therefore, the controllable illumination device of the present invention can drive or completely drive the light-emitting elements by the driving circuit portion by turning on and off the external power source, so that the light-emitting elements are partially or completely turned off. As described above, since the illumination device according to the present invention has a point-off control circuit in the body of the illumination device, when the controllable illumination device of the present invention is used in conjunction with an external power source, the user may not The M4 丄 8252 can be replaced or retrofitted with a component or circuit, even if it is easy to make this creation. = The lighting element of the lighting device is partially closed.
