The method of use of the preferred embodiment will be further described by the life extension of the d-light-emitting body and the energy-saving control method (8〇). For example, a street lamp, a garden lamp, and the like, which are required to be illuminated for a long time and related to ambient light brightness, are used as an example, and the preferred embodiment uses two parallel light string modules (4 turns) as an example to illustrate the light emitting diode. The step of extending the life of the body and the method for controlling the energy saving (8〇) may include: starting timing (81), first dimming (82), judging the first period (83), and second dimming (84) Judging the second period of time (85), the third stage of dimming (86), and the third period of time (87). The start timing (81) step is that the total monitoring module (1) is started after the preferred embodiment of the 201023691 is turned on. For example, in a general streetlight application design, the overall monitoring module (10) can internally set a timer to automatically turn on the preferred embodiment at a particular time (e.g., 1 8:00) and begin timing after turning it on. Ο In the first stage of dimming (82), the total monitoring module (1〇) controls a voltage feedback control circuit (22) and a corresponding constant current circuit (424) to output voltage, The current is supplied to a specific string unit (44) or a plurality of specific string units (44). For example, it is assumed that the preferred embodiment includes a plurality of string units (44) numbered as s〇~ S9. When performing the first dimming step, the total monitoring module (10) may first open the first seven groups (ie, s〇~s6) of the string unit (44), wherein the total monitoring module (1) 〇) The total number of light string units (44) that can be operated each time can be determined according to internal settings, or the light string unit (44) can be adjusted according to the sensing result of the light sensing module (50). The total number of). The step of the first stage dimming (82) can be designed according to the usage habit of the preferred embodiment. For example, when the preferred embodiment is used for street lighting, it is necessary to have more pedestrians in the early stage of the night. The brightness of the street lamp is to improve the safety of the pedestrian or the vehicle. Therefore, the total monitoring ^ (10) can select the voltage feedback control circuit (22) having the highest voltage and current and the constant current circuit (424) to output to each of the working a first ladder light string unit (44), wherein the so-called first ladder light string unit (44) can be designed as a single light string, or a plurality of light strings, the previous number is like a light For example, the string is S0~S3, which is the first ladder string unit, and ~%, Μ~S9 are the second ladder and the third ladder string unit respectively. ~ In order to protect the first ladder light string unit (44) for a long time: heat: and 201023691 cause permanent damage, please refer to the fourth figure, the first stage of dimming (82) step can further include ·· Outputting the first stage dimming power to the Nth string (822), determining whether the string rotation condition (824), N=N+ 1 (826# program is satisfied. The output first stage dimming power to the Nth string (822), the total monitoring unit (10) outputs a first stage of dimming power to the Nth string unit by one of the voltage feedback control circuit (22) and the constant current circuit (424). The ''N' light string unit (44) is the number of the light string unit (44) to which the total monitoring module (1〇) is actually connected, for example, one of the aforementioned s〇~S9 ones can be written. It is: N={S0, S1...S9}, which respectively represent the light string unit (44) numbered s〇 to S9, and the total monitoring unit (1Q) is based on the internal setting after the program starts. And programming, given N an initial value (eg N == 〇)' and output the power to the Nth Q (822) step when outputting the first stage dimming power to the Nth string (822) step SG) light string unit (44). As mentioned above, the Nth light string can also represent a plurality of light string units (44) according to design, for example, 'N=〇 (indicated by N0), representing the light string N〇= {s1, s2, s3, S4,

β熱’達到保護各燈串單元(44)之效果。另外,前述所謂之N ~ {〇, 2…9}序列係為遞迴關係,也就是說若當數值遞增後 產生Ν>9時’則Ν回到N=Q之狀況。若僅有兩個燈串單 凡(44),則代表兩個燈串單元(44)輪流休息。若如前述每一 梯工作的燈串單元(44)數量為複數個時,N的最大值則小於 燈串單元(44)之個數。舉例而言,依據設計同時讓8個燈 串單元(44)工作而僅有兩個燈串單元(44)休息的狀況下,n 可此的整數值為0〜4(只要5次之後,每一個燈串單元均完 β成休息一次)。 仍%參考第三圖所示,該判斷已屆第一段時間(83)步 驟中,係為該總監控單元(5〇〉依據該開始計時(81)步驟所累 计的時間,判斷累計時間是否已經超過一第一段時間(例如 12〇分鐘、1 80分鐘···等),當判斷結果為是,則進行下一 V驟(84),反之,則回到該第一段調光(82)步驟。如此,本 較佳實施例可以依據設計需求,預先設定該第一段時間之 長^進行調光動作’沿用前述範例,當本較佳實施例於1 8 : 〇〇時開始計時’而該第一段時間設定為1 80分鐘,則代表 13 201023691 21 : 00時即會屆滿第-段時間。 該第二段調光(84〗牛 ,驟,S滿足該第一段時間後,該 總監控模組(10)則選握s t ^ 、擇另一組的電壓回授控制電路(22)定 電流電路(424),將—鉍把 、、 較低的定電壓、定電流輸出給其中一 錢串早兀(44)。由於該第—段調光(82)與該第二段調光(叫 步驟,該總監控模組(10)所輸出的功率列,因此,本較 佳實施例可以依據時間,自動設定亮度,達到節能之功效。 ❹The β heat 'reaches the effect of protecting each string unit (44). In addition, the aforementioned sequence of N ~ {〇, 2...9} is a recursive relationship, that is, if 数值>9 is generated when the value is incremented, then Ν returns to the state of N=Q. If only two strings are used (44), then the two string units (44) take turns to rest. If the number of light string units (44) for each ladder operation is plural, the maximum value of N is smaller than the number of light string units (44). For example, according to the design, when 8 light string units (44) are working and only two light string units (44) are resting, n can have an integer value of 0 to 4 (as long as 5 times, each time One string unit is finished with β to take a break). Still refer to the third figure, the judgment has been in the first period (83) step, is the total monitoring unit (5〇> according to the time accumulated in the start timing (81) step, determine whether the accumulated time is Has exceeded a certain period of time (for example, 12 minutes, 1 80 minutes, etc.), when the judgment result is yes, the next V step (84) is performed, otherwise, the first stage dimming is returned ( 82) Steps. In this way, the preferred embodiment can preset the length of the first period of time according to the design requirements, and perform the dimming operation. The preceding example is used. When the preferred embodiment starts at 18: 〇〇, the timing is started. 'When the first period of time is set to 1 80 minutes, it means 13 201023691 21 : 00 will expire the first period of time. The second section of dimming (84〗 cattle, sudden, S meet the first period of time The total monitoring module (10) selects st ^ and selects another set of voltage feedback control circuit (22) constant current circuit (424) to turn on, lower, constant voltage, constant current output Give one of the money to the early (44). Because of the first-stage dimming (82) and the second-stage dimming (called In the step, the power column output by the total monitoring module (10), therefore, the preferred embodiment can automatically set the brightness according to the time to achieve the energy saving effect.

For the second period of time, the second period of time may be the same as or different from the first period of time. The third stage dimming (86) and the third period (87) of the judgment have the same operation mode as the steps (84) and (85), and the difference lies in the third stage dimming (just 'output' The power of each string unit is different, and the second period of time (87) determines whether the accumulated time has exceeded a third period of time. Thereby, the LED illumination for the purpose can save more than the traditional illumination. If the energy source is further used in this preferred embodiment, it can be saved and measured. It can be calculated as follows: (1) _ Assume that the power of the mercury lamp used in the original street lamp is from 18: 00 pm to 6:00 pm on the next day: 〇〇v 》r ί 2 hours, the power consumed by the mercury lamp is E1 = P*12 = 12P (watt hours).
