Description
本發明係有關一種減少發光二極體燈具功率消耗之控制電路模組，尤指一種可減少電路功率的消耗及實現高低電壓調節補償之電路。The invention relates to a control circuit module for reducing power consumption of a light-emitting diode lamp, in particular to a circuit capable of reducing power consumption of a circuit and realizing high and low voltage adjustment compensation.
按，人們得以發展各種技術，創作出適用於人們生活所需之商品，照明設備絕對是一個重大的關鍵，因為在電燈發明之前，幾乎所有的工作在太陽下山後即無法進行；但有了照明設備後，在夜晚裏仍可進行所有生產及技術研發工作，因此照明設備實為近代技術得以精進之一大利器。According to, people can develop various technologies and create goods suitable for people's lives. Lighting equipment is definitely a major key, because before the invention of electric lights, almost all work could not be done after the sun went down; but with lighting After the equipment, all production and technical research and development work can still be carried out at night, so the lighting equipment is one of the great tools for modern technology.
在現代的照明設備中，人們的視覺感受影響了整體照明設備的設計與規範，照明設備與一般光學系統所追求目標不盡相同，有的需要應用於高亮度的場合，需要功率大一點的燈具；有的是追求光源均勻的亮度，需要好的導光裝置來達成。而於現今地球面臨資源竭盡的今日，燈具也應追求綠能環保的目標，降低燈具功率達到省電功能，但是還是要講究照明的亮度。而發光二極體具有省電環保的特性，因此綠色的燈具研發重點即在於發光二極體的改善，如何增加其亮度、發光均勻度、使用壽命及降低生產成本，方可取代現有鎢絲燈、日光燈等燈具，本發明正為針對發光二極體所研發出新的控制電路模組，來使發光二極體燈具成為未來燈具市場的主流。In modern lighting equipment, people's visual experience affects the design and specification of the overall lighting equipment. Lighting equipment and general optical systems pursue different goals. Some need to be applied to high-brightness occasions. Some are pursuing uniform brightness of the light source and require a good light guide to achieve. Today, when the earth is facing the exhaustion of resources, the lamps should also pursue the goal of green energy and environmental protection, reduce the power of the lamps to achieve the power-saving function, but still pay attention to the brightness of the lighting. The light-emitting diode has the characteristics of energy saving and environmental protection. Therefore, the focus of green lighting research and development lies in the improvement of the light-emitting diode, how to increase its brightness, uniformity of illumination, service life and production cost, in order to replace the existing tungsten lamp The invention discloses a new control circuit module for the light-emitting diode, so that the light-emitting diode lamp becomes the mainstream of the future lamp market.
請參閱圖一A、B所示，習知的發光二極體控制電路主要為利用三組開關(SW1、SW2、SW3)來控制三組發光二極體，而控制電流區段即如圖一A所揭露，分別為(I1、I2、I3)，於I1的電流區段，經由一發光二極體電流設定器5之設定及一運算放大器8做為參考信號，即可使第一組發光二極體被點亮；於I2的電流區段，第一、二組發光二極體同時被點亮；於I3的電流區段，第一、二、三組發光二極體同時被點亮，而電流區段即以I1－＞I2－＞I3－＞I2－＞I1的週期循環下去，如此所有複數組發光二極體皆可在電流區段循環控制情況下被平均點亮及熄滅。Referring to FIG. 1A and B, the conventional LED control circuit mainly uses three groups of switches (SW1, SW2, and SW3) to control three groups of LEDs, and the control current section is as shown in FIG. As disclosed in A, (I 1 , I 2 , I 3 ), the current section of I 1 is set as a reference signal via the setting of a light-emitting diode current setter 5 and an operational amplifier 8 as a reference signal. The first group of light-emitting diodes are illuminated; in the current section of I 2 , the first and second groups of light-emitting diodes are simultaneously illuminated; in the current section of I 3 , the first, second and third groups of light-emitting diodes The polar body is illuminated at the same time, and the current section is cycled with a period of I 1 -> I 2 -> I 3 -> I 2 -> I 1 , so that all complex array light-emitting diodes can be in the current section It is illuminated and extinguished on average in the case of cycle control.
當第一開關(SW1)導通時，其消耗功率的公式為Vin-VF1*I1；當第二開關(SW2)導通時，其消耗功率的公式為Vin-VF1-VF2*I2；當第三開關(SW3)導通時，其消耗功率的公式為Vin-(VF1-VF2-VF3)*I3。When the first switch (SW1) is turned on, the formula for consuming power is Vin-VF1*I1; when the second switch (SW2) is turned on, the formula for consuming power is Vin-VF1-VF2*I2; when the third switch When (SW3) is turned on, the formula for the power consumption is Vin-(VF1-VF2-VF3)*I3.
由上述三公式可得知，該些消耗功率並未非完全應用於電路，一部份為做虛功而白白消耗掉(如圖一B之虛線部份)，對於講求節能的概念而言，是不符合需求的，本發明正為針對此一缺失做一改善，來達到更加完善的目的。It can be known from the above three formulas that the power consumption is not completely applied to the circuit, and part of it is consumed for virtual work (as shown by the dotted line in Fig. 1B). For the concept of energy saving, It is not in line with the demand, and the present invention is aimed at improving the lack of this to achieve a more perfect purpose.
