200945949 九、發明說明： 【發明所屬之技術領域】 本發明係關於一種無溫度感測器之發光二極體照明裝 置及其溫度控制方法，尤指一種適用於控制發光二極體照 5 明裝置照度與演色性之無溫度感測器之發光二極體照明裝 置及其溫度控制方法。 【先前技術】 近年來’由於發光二極體（led)因其有發光效率高、耗 10 電量少、使用壽命長、及元件體積小等優點，使得發光二 極體能應用於各種照明裝置中。目前發光二極體普遍應用 於紅綠燈、手電筒、或發光二極體投射燈等發光設備中， 且未來發光二極體更具有取代各式各樣發光設備的潛力， 如取代目前應用於平面顯示器之背光模組。 15 其中’發光二極體照明裝置已逐漸應用在日常生活之 各種照明裝置中，如發光二極體投射燈、展示照明或室外 Φ 照明等，並逐漸取代效率較低的白熾燈。除此之外，由於 白熾燈發光時會將90 %的電能轉換成熱能，造成能源的大量 浪費。因此，現今歐盟以及許多國家已陸續宣布將全面禁 20 用白熾燈。 雖然發光二極體具有發光效率高及低耗電量等優點， 然而將發光二極體應用於裝飾性照明上時，往往面臨因發 光二極體溫度升高而造成光譜改變的缺點，而此缺點對於 裝飾性照明而言是為一種嚴重的問題。如圖1所示，其為白 200945949 ' 光發光二極體發光單元在20與80°C下光譜變化圖，其中x 轴為白光發光二極體發光單元之發光波長，Y軸為白光發光 二極體發光單元之發光強度。如圖所示，分別在2〇。〇與80 °〇時，白光發光二極體發光單元之波長有偏移的現象產 5 生。因此’當發光二極艘溫度改變時，由於光譜波長的偏 移，導致色差的產生。 目前已知可應用散熱鰭片、流體導熱管、或風扇來幫 助發光二極體降低溫度。這些裝置皆可以降低發光二極體 〇 溫度。然而’應用在裝飾性照明上時，若無外加其他溫度 10 感測器偵測發光二極體之溫度，則無法達到發光二極趙溫 度管理。況且，一般為達到控制温度的效果，往往會在發 光一極體照明裝置上設置溫度感測器，以量測發光二極體 之溫度β然而，溫度感測器一般是測量發光二極體周圍環 境之溫度，並非直接測量發光二極體之溫度。由圖i可知， 15 發光二極體的溫度與其波長的變化有極大的影響，為了避 免色差的情形發生，如何精準的測量出發光二極體之溫度 是一個重要的問題。 因此，業界極需發展一種能有效偵測發光二極體溫 度，並達到溫度管理之發光二極體照明裝置，以控制發光 20二極體之光譜波長。同時，若能發展出具有最佳化溫度管 理之發光二極體照明裝置，則能克服發光二極體因溫度而 導致照度及演色性變化等問題。 【發明内容】 200945949 -本發明之主要目的係在提供一種無溫度感測器之發光 t體“、、明裝置，俾能在不需要另外設置溫度感測器之情

接下來，將以一驅動線路圖詳細說明本實施例之無溫 度感測器之發光二極體照明裝置之線路設計及其溫度控制 方法》 請參閱圖3，此為本實施例之無溫度感測器之發光二極 體照明裝置之驅動線路圖。此外’並請同時參閲圖4,此為 本實施例之無溫度感測器之發光二極體照明裝置之溫度控 制方法的流程圖。而本實施例之溫度控制方法包括下列步 驟： 步驟（Α):首先，電流供應裝置12供應電源至控制模組 11，以驅動發光二極體發光單元141，142。於本實施例中， 控制模組11是以10kHz、50%之電流負載週期驅動發光二極 體發光單元141，142。 步驟（B):接下來，電流感應元件13可感測一訊號，並 將此訊號傳送至控制模組11。在此，電流感應元件13所感 測到之訊號為與電流感應元件13電性連接之發光二極體發 光單元141之前饋電流。此外，圖5為發光二極體發光單元 之前饋電流-溫度關係曲線圖，當發光二極體發光單元溫度 升高時，發光二極體發光單元之前饋電流會隨之下降，利 11 200945949 用此前饋電流與溫度間之關係曲線，可將發光二極體發光 單元之前饋電流訊號轉換成發光二極體發光單元之溫度。 因此，請同時參閱圖4及圖5，透過電流感應元件13所 感測到之發光二極體發光單元141之前饋電流，控制模組11 5 可利用發光二極體發光單元之前饋電流-溫度關係曲線，將 此訊號（前饋電流）對應至與電流感應元件141電性連接之發 光二極體發光單元141之溫度。 步驟（C):最後，請同時參閱圖3及圖4，控制模組11則 依據此訊號（發光二極體發光單元之前饋電流）調整驅動發 10 光二極體發光單元141，142之電流負載週期。 而當發光二極體發光單元141之前饋電流高於一預設 範圍時，控制模組13則調整驅動發光二極體發光單元之電 流負載週期。在此，調整驅動發光二極體發光單元141，142 之電流負載週期，即是調整發光二極體發光單元141，142 15 發光頻率及發光時間長短等操作參數。於本實施例中，控 制模組11即根據發光二極體發光單元141之前饋電流及前 饋電流所對應之溫度，調整發光二極體發光單元141，142 之發光時間長短，以達到控制發光二極體發光單元141，142 之溫度的效果。 20 比較例1 如圖6所示，此為本發明比較例1之發光二極體發光 裝置。此發光二極體發光裝置包含：一控制模組11、以及 複數個發光二極體發光單元14,且透過一電源供應裝置12 以供應發光二極體發光裝置所需之驅動電力。 12 200945949 5 ❹ 10 15 Ο 20 於比較例1中，共使用20個白光發光二極體發光單元

者’在外在環境温度介於20及8(TC下，分別對此兩發光二 極體照明裝置進行照度及CIE色度之測試，其結果如圖7、 及圖8所示。 圖7為本發明實施例1之無溫度感測器之發光二極體 照明裝置與比較例1之發光二極體照明裝置之相對照度變 異曲線圖，其中X軸為發光二極體照明裝置之外在溫度， 而Y轴為發光二極體照明裝置之相對照度。如圖7所示， 比較例1之發光二極體照明裝置在外在環境溫度為2〇與8〇 °C下之兩相對照度之間存在有25%的差異。然而，實施例j 之無溫度感測器之發光二極體照明裝置，在外在環境溫度 為20與80艺下之兩相對照度之間的卻小於5%。由此可知， 實施例1之無溫度感測器之發光二極體照明裝置及其溫度 控制方法，確實能維持此無溫度感測器之發光二極體照明 裝置之照度的恆定。 圖8為本發明實施例1之無溫度感測器之發光二極體 13 200945949

另外，透過1960CIE UCS座標轉換，可計算出實施例 1與比較例1之色度差。計算的結果顯示，在外在環境溫度 為20及80°C下，比較例1之發光二極體照明裝置的色度差 為0.1334 ’而在外在環境溫度為20及80°C下，實施例1 之無溫度感測器之發光二極體照明裝置的色度差為 20 0·1048。由此可知’實施例1之無溫度感測器之發光二極體 照明裝置及其溫度控制方法，確實能維持此無溫度感測器

80°C下之光譜變化圖，其中X軸為白光發光二極體發光單 元之發光波長’ Y轴為白光發光二極體發光單元之發光強 度。由此結果發現，分別在20與80。(：下，透過控制實施例 1之白光發光二極體發光單元，白光發光二極體發光單元的 發光波長幾乎沒有變化。因此，即使外在環境溫度變化， 實施例1之無溫度感測器之發光二極體照明裝置，經溫度 控制後’發光二極體發光單元之光譜波長沒有偏移的現 象。故實施例1之無溫度感測器之發光二極體照明裝置及 其溫度控制方法’確實能消弭發光二極體發光單元因溫度 升高所導致的藍光紜移現象，而能避免色差問題的產生。 這亦同時說明實施例1之無溫度感測器之發光二極體照明 裝置’為何能維持良好演色性之原因。 實施例2 如圖10所示，此為本發明實施例2之無溫度感測器之 發光二極體照明裝置之媒動線路圖。 在本實施例中’此無溫度感測器之發光二極體照明裝

Description of the Invention: [Technical Field] The present invention relates to a light-emitting diode lighting device without temperature sensor and a temperature control method thereof, and more particularly to a device for controlling a light-emitting diode Light-emitting diode lighting device with illuminance and color rendering without temperature sensor and temperature control method thereof. [Prior Art] In recent years, due to the advantages of high luminous efficiency, low power consumption, long service life, and small component size, the light-emitting diode (LED) can be applied to various lighting devices. . At present, light-emitting diodes are commonly used in lighting devices such as traffic lights, flashlights, or light-emitting diode projection lamps, and future light-emitting diodes have the potential to replace various types of light-emitting devices, such as replacing the current use in flat-panel displays. Backlight module. 15 Among them, the 'light-emitting diode lighting device has been gradually applied to various lighting devices in daily life, such as LED projection lamps, display illumination or outdoor Φ illumination, and gradually replaced the less efficient incandescent lamps. In addition, since incandescent lamps emit 90% of the electrical energy into heat, a lot of energy is wasted. Therefore, the European Union and many countries have announced that they will completely ban 20 incandescent lamps. Although the light-emitting diode has the advantages of high luminous efficiency and low power consumption, when the light-emitting diode is applied to decorative lighting, it often faces the disadvantage of spectral change due to the temperature rise of the light-emitting diode. Disadvantages are a serious problem for decorative lighting. As shown in Fig. 1, it is a white light of the 200945949 ' light-emitting diode light-emitting unit at 20 and 80 ° C, where the x-axis is the light-emitting wavelength of the white light-emitting diode light-emitting unit, and the Y-axis is the white light-emitting light. The luminous intensity of the polar body light-emitting unit. As shown in the figure, they are at 2〇. When 〇 and 80 °〇, the wavelength of the white light-emitting diode light-emitting unit is shifted. Therefore, when the temperature of the light-emitting diode is changed, the chromatic aberration is caused due to the shift of the spectral wavelength. Heat sink fins, fluid heat pipes, or fans are known to help reduce the temperature of the light emitting diode. These devices can reduce the temperature of the LEDs. However, when applied to decorative lighting, if no other temperature sensor is used to detect the temperature of the light-emitting diode, the temperature management of the light-emitting diode cannot be achieved. Moreover, generally, in order to achieve the effect of controlling the temperature, a temperature sensor is often disposed on the light-emitting one-pole illumination device to measure the temperature of the light-emitting diode. However, the temperature sensor generally measures the circumference of the light-emitting diode. The temperature of the environment is not directly measured by the temperature of the light-emitting diode. It can be seen from Fig. i that the temperature of the light-emitting diode has a great influence on the change of its wavelength. In order to avoid the occurrence of chromatic aberration, how to accurately measure the temperature of the light-emitting diode is an important problem. Therefore, it is highly desirable for the industry to develop a light-emitting diode illumination device that can effectively detect the temperature of a light-emitting diode and achieve temperature management to control the spectral wavelength of the light-emitting diode. At the same time, if a light-emitting diode lighting device with optimized temperature management can be developed, problems such as illuminance and color change of the light-emitting diode due to temperature can be overcome. SUMMARY OF THE INVENTION 200945949 - The main object of the present invention is to provide a light-emitting sensor without a temperature sensor, and a device capable of controlling a light-emitting diode without requiring a separate temperature sensor. Illumination and color rendering of the illuminating device. 5 I. Another object of the invention is to provide a temperature control method for a illuminating diode illuminating device for a temperature sensor without using a illuminating diode. The function of the forward current) is to perform the temperature detection of the light-emitting diode to achieve an optimized temperature management effect. To achieve the above object, the light-emitting diode-free lighting device of the temperature sensor of the present invention comprises: a control mode The group, the plurality of light emitting diodes, and a current sensing element, wherein the control module is electrically connected to the line, and the plurality of light emitting diodes are electrically connected to the line, and the other current sensing element And electrically connected to at least one of the light emitting diodes and the circuit.
