請參閱圖1~圖3所示，本發明之照明裝置照度測量校正系統10主要係對指定區域20之複數個照明裝置30(可為燈具)之照度進行測量及校正，俾供判斷指定區域20內該照明裝置30的照度是否與自然光照度相符；其方法係先取得該照明裝置30的照度，並將該照明裝置30的照度與自然光照度進行比較，依據該照明裝置30高於或低於自然光照度後，再透過本發明之照明裝置照度測量校正系統10對各該照明裝置30照度進行校正，使各該照明裝置30照度符合自然光之照度，避免當該照明裝置30照度低於自然光照度時，無形間傷害使用者眼部；又或當該照明裝置30照度高於自然光照度時，無形間浪費該照明裝置30多餘的電力。Referring to FIG. 1 to FIG. 3, the illumination device illumination measurement and correction system 10 of the present invention mainly measures and corrects the illumination of a plurality of illumination devices 30 (which can be lamps) in the designated area 20, and determines the designated area 20 for use. Whether the illuminance of the illuminating device 30 corresponds to the natural illuminance; the method first obtains the illuminance of the illuminating device 30, and compares the illuminance of the illuminating device 30 with the natural illuminance, according to whether the illuminating device 30 is higher or lower than the natural After the illuminance, the illuminance measurement calibration system 10 of the present invention calibrates the illuminance of each of the illuminating devices 30, so that the illuminance of each illuminating device 30 conforms to the illuminance of natural light, and avoids when the illuminance of the illuminating device 30 is lower than the natural illuminance.

進一步說明本發明之照明裝置照度測量校正系統10包含：It is further explained that the illumination device illumination measurement correction system 10 of the present invention comprises:
一照度計測量單元11，將該照度計測量單元11電性連接於各該照明裝置30，並測量得到複數個照度計照度數值；An illuminometer measuring unit 11 electrically connecting the illuminometer measuring unit 11 to each of the illuminating devices 30, and measuring a plurality of illuminance illuminance values;
一感光測量單元12，將該感光測量單元12電性連接於各該照明裝置30，並測量得到複數個感光照度數值；a photosensitive measuring unit 12, the photosensitive measuring unit 12 is electrically connected to each of the lighting devices 30, and a plurality of illuminance values are measured;
一灰階調整單元13，其灰階值介於0~256，將該灰階調整單元13分別與該照度計測量單元11、該感光測量單元單元12電性連接，用以接收複數個照度計照度數值及複數個感光照度數值，其中該灰階調整單元13係為一Arduino面板，Arduino面板是一個單晶片微控制器，使用Atmel AVR單片機，具有一可簡易輸出/輸入（simple I/O）介面板(茲因Arduino面板係為習知技術，相關技術手請容本發明人不再贅述)，故藉由該灰階調整單元13之輸出/輸入（simple I/O）介面板可將接收到的複數個照度計照度數值及感光照度數值輸出一照度計照度與灰階對應關係曲線110及一感光照度與灰階對應關係曲線120，如圖2所示， 當該灰階調整單元13之灰階值位於25時，該感光照度與灰階對應關係曲線120顯示出感光照度數值為95，照度計照度與灰階對應關係曲線110顯示出照度計照度數值為100；而當該灰階調整單元13之灰階值位於100時，該感光照度與灰階對應關係曲線120顯示出感光照度數值為135，照度計照度與灰階對應關係曲線110顯示出照度計照度數值為360，由此可知藉由調整該灰階調整單元13之灰階值(0~256)可相對改變照度計照度數值及感光照度數值；a gray scale adjusting unit 13 having a gray scale value ranging from 0 to 256, and the gray scale adjusting unit 13 is electrically connected to the illuminometer measuring unit 11 and the sensitometric unit 12, respectively, for receiving a plurality of illuminometers The illuminance value and the plurality of illuminance values, wherein the gray scale adjusting unit 13 is an Arduino panel, and the Arduino panel is a single-chip microcontroller, which uses an Atmel AVR microcontroller and has a simple output/input (simple I/O). The interface panel (the Arduino panel is a conventional technology, and the related art will not be described by the inventor), so the output can be received by the output/input (simple I/O) interface of the grayscale adjustment unit 13. The plurality of illuminance illuminance values and the illuminance value output illuminance illuminance and gray scale correspondence curve 110 and a illuminance and gray scale correspondence curve 120, as shown in FIG. 2, When the grayscale value of the grayscale adjusting unit 13 is at 25, the illuminance and grayscale correspondence curve 120 shows that the illuminance value is 95, and the illuminance illuminance and grayscale correspondence curve 110 shows that the illuminance illuminance value is 100; when the grayscale value of the grayscale adjustment unit 13 is at 100, the illuminance and grayscale correspondence curve 120 shows that the illuminance value is 135, and the illuminance illuminance and grayscale correspondence curve 110 shows the illuminance meter. The illuminance value is 360, and it can be seen that the illuminance illuminance value and the illuminance value can be relatively changed by adjusting the grayscale value (0~256) of the grayscale adjusting unit 13;
另，本發明之照明裝置照度測量校正系統10更包含：In addition, the illumination device illumination measurement correction system 10 of the present invention further comprises:
一照度測量校正單元14，該照度測量校正單元14電連連接該灰階調整單元13，並將該灰階調整單元13所接收之複數個照度計照度數值及感光照度數值分別以X、Y軸定義，藉以得到一感光照度與照明裝置照度校正曲線140，如圖3所示，當Y軸之感光照度數值為90時所對應到X軸得到之照度計照度數值為100，而當Y軸之感光照度數值為130時所對應到X軸得到之照度計照度數值為300。An illuminance measurement correction unit 14 is electrically connected to the gray scale adjustment unit 13 and the plurality of illuminance illuminance values and illuminance values received by the gray scale adjustment unit 13 are respectively X and Y axes Defining, thereby obtaining a illuminance and illumination device illumination correction curve 140, as shown in FIG. 3, when the illuminance value of the Y-axis is 90, the illuminance value corresponding to the X-axis is 100, and when the Y-axis is When the illuminance value is 130, the illuminance value corresponding to the X-axis is 300.
舉例說明，請參閱圖3所示，如指定區域20所需之自然光預設照度數值為500，而本發明之照度測量校正單元14測量指定區域20中之照明裝置30所得到的感光照度數值為130，且由該感光照度與照明裝置照度校正曲線140顯示出當感光照度數值為130時，所對應到X軸之照度計照度數值為300，如此表示指定區域20中的照明裝置30之照度計照度數值300並不足夠自然光預設照度數值500，換句話說，在指定區域20原本必需要有500照度的光源，但經測量後該照明裝置30僅提供300照度的光源，尚缺乏200照度的光源，故必需對該照明裝置30的照度進行校正，令該照明裝置30的照度再提升200照度，以符合所需500照度的光源；For example, as shown in FIG. 3, if the natural light preset illuminance value required for the designated area 20 is 500, the illuminance measurement correcting unit 14 of the present invention measures the illuminance value obtained by the illuminating device 30 in the designated area 20 as 130, and the illumination illuminance correction curve 140 shows that when the illuminance value is 130, the illuminance value corresponding to the X-axis is 300, thus indicating the illuminance meter of the illumination device 30 in the designated area 20. The illuminance value 300 is not sufficient for the natural light preset illuminance value 500. In other words, the light source of 500 illuminance is originally required in the designated area 20, but after the measurement, the illuminating device 30 only provides a light source of 300 illuminance, and the illumination is still lacking 200 illuminance. The light source is required to correct the illuminance of the illuminating device 30, so that the illuminance of the illuminating device 30 is further increased by 200 illuminance to meet the required illumination of 500 illuminance;
而本發明之照度校正方式係通過調整該灰階調整單元13的灰階值(0~256)來改變該照明裝置30的照度，請再參閱圖2所示，當Y軸呈現的感光照度數值為130時，由感光照度與灰階對應關係曲線120顯示出該灰階調整單元13之灰階值為75，因此可將該灰階調整單元13之灰階值由75調整至175，而當該灰階調整單元13之灰階值為175時，再由感光照度與灰階對應關係曲線120顯示出Y軸的感光照度數值已由原來的130提昇為150，此時請再配合參閱圖3所示，當感光照度數值為150時由感光照度與照明裝置照度校正曲線140顯示出所對應X軸之照度計照度數值已提升至500(如圖3所示)，據此達到將該照度計照度數值由原先的300照度校正為500照度，補足原先缺乏的200照度，同時符合指定區域20之自然光預設照度數值500照度的條件。The illuminance correction method of the present invention changes the illuminance of the illuminating device 30 by adjusting the grayscale value (0~256) of the grayscale adjusting unit 13, please refer to FIG. 2 again, and the illuminance value of the y-axis is displayed. When it is 130, the gray scale value of the gray scale adjusting unit 13 is 75 by the illuminance and gray scale correspondence curve 120, so the gray scale value of the gray scale adjusting unit 13 can be adjusted from 75 to 175, and When the grayscale value of the grayscale adjustment unit 13 is 175, the illuminance and grayscale correspondence curve 120 shows that the illuminance value of the y-axis has been increased from the original 130 to 150, and please refer to FIG. 3 again. As shown, when the illuminance value is 150, the illumination illuminance correction curve 140 shows that the illuminance value of the corresponding X-axis illuminance has been increased to 500 (as shown in FIG. 3), thereby achieving the illuminance of the illuminance meter. The value is corrected from the original 300 illuminance to 500 illuminance, complementing the previously lacking 200 illuminance, while meeting the condition that the natural light preset illuminance value of the designated area 20 is 500 illuminance.
反之，請再參閱圖3所示，若照度測量校正單元14測量該照明裝置30後所得到的感光照度數值為170時，由感光照度與照明裝置照度校正曲線140所對應到X軸之照度計照度數值顯示600照度，如此與指定區域20原先預設之自然光照度數值500照度相比較下多出100照度，因同樣必需對該照明裝置30的照度進行校正，令該照明裝置30的照度減少100照度，以符合自然光預設照度數值為500照度；On the contrary, please refer to FIG. 3 again, if the illuminance value obtained by the illuminance measurement correcting unit 14 after measuring the illuminating device 30 is 170, the illuminance meter corresponding to the X-axis by the illuminance and illumination device illumination correction curve 140 The illuminance value shows 600 illuminance, so that 100 illuminance is compared with the illuminance of the natural illuminance value 500 originally preset in the designated area 20, because it is also necessary to correct the illuminance of the illuminating device 30, so that the illuminance of the illuminating device 30 is reduced by 100. Illuminance, in accordance with the natural light preset illuminance value of 500 illuminance;
而校正方式同樣藉由調整該灰階調整單元13的灰階值(0~256)來改變該照明裝置30的照度，請再參閱圖2所示，當感光照度數值為170時，由感光照度與灰階對應關係曲線120顯示出該灰階調整單元13之灰階值為255，故將該灰階調整單元13之灰階值由255調整至175，同理當該灰階調整單元13之灰階值為175時，再由感光照度與灰階對應關係曲線120顯示出所對應到Y軸之感光照度數值為150，而當感光照度數值為150時，請再參閱圖3所示，感光照度與照明裝置照度校正曲線140顯示出所對應到X軸之照度計照度數值為500，據此表示已將該照明裝置30之照度校正至符合指定區域20之自然光預設照度數值500的照度條件。The calibration method also changes the illumination of the illumination device 30 by adjusting the grayscale value (0 to 256) of the grayscale adjustment unit 13, please refer to FIG. 2 again, when the illumination value is 170, the illumination sensitivity is Corresponding to the grayscale mapping curve 120, the grayscale value of the grayscale adjustment unit 13 is 255, so the grayscale value of the grayscale adjustment unit 13 is adjusted from 255 to 175, and the grayscale adjustment unit 13 is grayed out. When the order value is 175, the illuminance and gray scale correspondence curve 120 shows that the illuminance value corresponding to the Y axis is 150, and when the illuminance value is 150, please refer to FIG. 3, the illuminance and The illuminance illuminance correction curve 140 shows that the illuminance value corresponding to the X-axis is 500, which indicates that the illuminance of the illuminating device 30 has been corrected to the illuminance condition of the natural light preset illuminance value 500 of the designated area 20.
由上述可知，本發明之照明裝置照度測量校正系統10對於該照明裝置30的照度校正，其主要技術手段係利用該照度測量校正單元14分別與該灰階調整單元13及與該照明裝置30電性連接，藉由感光照度與照明裝置照度校正曲線140判讀感光照度數值及照度計照度數值，並依據感光照度與灰階對應關係曲線120得知感光照度數值與該灰階調整單元13之灰階值的對應位置，再透過調整該灰階調整單元13之灰階值(0~256)改變照度計照度數值及感光照度數值；換言之本發明係藉由該照度測量校正單元14所顯示的感光照度數值得知該照明裝置30之照度，進而與指定區域20所需自然光預設照度數值進行比較並做適當地照度校正。It can be seen from the above that the illuminance correction of the illumination device illuminance measurement correction system 10 of the present invention is mainly used by the illuminance measurement correction unit 14 and the gray scale adjustment unit 13 and the illumination device 30, respectively. The illuminance and the illumination illuminance correction curve 140 are used to determine the illuminance value and the illuminance illuminance value, and the illuminance value and the gray scale of the gray scale adjustment unit 13 are obtained according to the illuminance and gray scale correspondence curve 120. The corresponding position of the value is changed by adjusting the gray scale value (0 to 256) of the gray scale adjusting unit 13 to change the illuminance illuminance value and the illuminance value; in other words, the illuminance displayed by the illuminance measurement correcting unit 14 The numerical value is used to know the illuminance of the illuminating device 30, and is then compared with the required natural light preset illuminance value of the designated area 20 and the illuminance correction is appropriately performed.
綜上所述，上述各實施例及圖式僅為本發明之較佳實施例而已，當不能以之限定本發明實施之範圍，即大凡依本發明申請專利範圍所作之均等變化與修飾，皆應屬本發明專利涵蓋之範圍內。In the above, the above embodiments and drawings are only the preferred embodiments of the present invention, and the scope of the present invention is not limited thereto, that is, the equivalent changes and modifications made by the scope of the present invention.
