Description of the Invention: [Technical Field] The present invention relates to the technical field of light-emitting diodes, and more particularly to a driving device for emitting a light-emitting diode. [Prior Art] A light-emitting diode (LED) is a principle that directly converts electric energy into light energy, and a voltage is applied to two terminals of the positive and negative electrodes in the semiconductor, and when the current passes through 'the electron is combined with the hole, 'remaining The energy is released in the form of light. Depending on the material used, the energy level of the photon enables the photon energy to produce light of different wavelengths, and the human eye can receive light of various colors. The principle of illuminating the illuminating diode is to use the inherent characteristics of the semiconductor, which is different from the principle of illuminating the heat generated by the incandescent lamp. Therefore, the illuminating diode is called a cold light source (c〇ld light). The light-emitting diode has the advantages of high durability, long life, low power consumption, and no harmful substances such as mercury, so the lighting market today has great expectations for light-emitting diode lighting. Fig. 1 is a voltage-current characteristic curve of a light-emitting diode. As shown in Fig. i, when the forward voltage Vf applied to the light-emitting diode is greater than 2.5 volts, the 20-diode is turned on, and the forward voltage Vf is smaller than 〇〇. It does not glow when it is volts. As can be seen from Fig. 1, the forward voltage Vf is preferably 2.5 to 3.0 volts, and the current of the light emitting diode is 20 mA to 30 mA. At the same time, as can be seen from Fig. 1, when the voltage applied to the light-emitting diode is too large, the light-emitting diode is damaged. Therefore, when the light-emitting diode is used, a plurality of light-emitting diodes are often connected in series so that the forward voltage Vf of each of the 25 light-emitting diodes is between 2.5 and 3.0 volts. As a result of the use of 3 201034513, the entire series of LED voltage and current are connected in series and a plurality of LEDs are connected in series, and the external voltage needs to be greater than a so-called starting voltage to emit light. The w-series, the I-to-port LEDs use a streaming power source 210, the first phase of the brigade, and the package-parent 230, and the first and the second body 220 and the second group of LEDs, x first— The starting voltage of the polar body 220 and the second group of light-emitting diodes 23A is 90 volts. 30 ❿ 10 *The output current voltage of the parental power supply 21〇 is equal to or greater than: G gang special time 'starts to start lighting the first group of light-emitting diodes 〇° when the alternating current voltage continues to rise and returns to 9G volts, The first set of light emitting diodes 220 is turned off. Similarly, when the output AC voltage is equal to or less than -90 volts, the second group of LEDs 230 is started to be turned on. When the output AC voltage continues to drop and rises by _9 volts, the second group of LEDs 230 is turned off. 15 Referring to Figure 3, the current waveform diagram of Figure 2 is shown, where the horizontal axis is time-varying and the current is mA (milliampere). As shown in FIG. 3, when the phase is about 30 degrees, the voltage starts to be greater than 9 〇 v, and the first group of light-emitting diodes 22 illuminates. At a phase of about 9 ,, the voltage turns to a maximum, and the current flowing through the first group of LEDs 22 约为 is about 20 5.2 mA. When the phase is 150 degrees to 21 degrees, the voltage is less than 9 〇 v and greater than
-90V，此時第一組發光二極體22〇及第二組發光二極體 230被關閉’故電流為〇mA。在相位約2 度時，電壓開 始小於-90V ’而點亮第二組發光二極體23…在相位約27〇 度時’電壓開達到最小值，流經第二組發光二極體230的 25 電流約為-5_2mAe在相位為330度〜360度時，電壓小於90V 4 201034513 且大於-90 V，此時第一組發光二極體22〇及第二組發光二 極體230被關閉，故電流為〇mA。 由圖3可知，第一組發光二極體22〇及第二組發光二 極體230有時被點亮有時被關閉’此會產生閃爍現象。而 5產生令人眼不舒服。故如圖2的習知技術並不適合使用於 照明設施。 圖4係另一習知發光二極體使用的示意圖。其工作原 理與圖2的習知技術近似，係將發光二極體作為整流器使 ® 用。在圖4的習知技術中，發光二極體仍存在有時被點亮 10有時被關閉的情形，故仍會產生閃爍現象。 圖5及圖6係又一習知發光二極體使用的示意圖。如 圖5所示’其係由一交流電源2 1 〇、一組發光二極體220及 半波整流器所組成240，而圖6中係由一交流電源21 〇、一 組發光一極體220及全波整流器所組成250。此種使用串 15聯的發光二極體加上半波/全波整流器的方式僅減少發光 二極體的使用數量，仍會產生閃爍的問題。 • 圖7及圖8係再一習知發光二極體使用的示意圖。如 圖7所示’其係由一交流電源210、一組發光二極體220、 半波整流器所組成240及濾波電容260，而圖8中係由一交 20流電源210、一組發光二極體220、全波整流器所組成250 及濾波電容260。此種使用串聯的發光二極體加上半波/ 全波整流器再加上濾波電容260的方式會產生濾波電容 260充電時，諧波過大且易導致充電脈衝電流的問題，進 而導致功率因數過低的現象。圖9係圖7及圖8中濾波電容 25 740充放電時之電流示意圖，如圖9所示，濾波電容260充 201034513 電時會產生相當大的充電脈衝電流，此容易造成交流電 源210的元件損壞’並由於諧波過大造成電網的污染。由 此可知，習知發光二極體之驅動技術仍有諸多缺失而有 予以改善之必要。 【發明内容】 本發明之目的主要係在提供一種發光二極體之驅動 裝置，以解決習知技術所產生的閃爍的問題，同時提升 能源使用效率。 10 15 20 依據本發明之一特色，本發明提出一種發光二極體 之驅動裝置，其包含一第一整流裝置、一第一組發光二 極體、一第二整流裝置、一第二組發光二極體及一第 二儲能裝置。該第一整流裝置連接至一電流源的第一 端以產生一整流電壓。該第一組發光二極體具有一第 一電極端及一第二電極端，其第二電極端連接至該第一 整流裝置，以接收該整流電壓，而產生照光。該第一儲 能裝置的第-電極端連接至該第—整流裝置及該第一組 發光一極體的第二電極端，以儲存或施放電能。該第二 整流裝置連接至該第一組發光二極體的第一電極端及該 第儲月匕裝置的第二電極端，以讓特定方向電流流通。 :第一組發光二極體具有一第—電極端及—第二電極 :’ f第二電極端連接至該第二整流裝置的輸出端及第 儲月b裝置的第二電極端。該第二儲能裝置的第一電極 端連接至該第二整流裝置的第二電極端及該第—組發光 二極體的第-電極端。其中，當該第—整流裝置沒有產 6 25 201034513 生。亥正机電流時，該第—儲能裝置施放電能，以供電給 該第’组發光二極體，該第二儲能裝置施放電能，以供 電給該第二組發光二極體。 八 5【實施方式] "月參見圖10，其係顯示本發明發光二極體之驅動裝 置600的方塊圖。該驅動裝置600包含一第一整流裝置 61〇_、一第—組發光二極體620、一第一儲能裝置63〇、一 第二整流裝置640、一第二組發光二極體65〇及一第二儲 10 能裝置660。 15 20 3亥第一整流裝置610之輸入端ό 11連接至一交流電源 670的第—端’以產生一整流電壓。該第一整流裝置610 較佳為-整流二極體，第一整流裝置61〇之輸入端611為 整流二極體之陽極，其輸出端612為整流二極體之陰極。 該第一組發光二極體62〇具有一第一電極端621及一At -90 V, at this time, the first group of light-emitting diodes 22 and the second group of light-emitting diodes 230 are turned off, so the current is 〇mA. When the phase is about 2 degrees, the voltage starts to be less than -90V' and the second group of light-emitting diodes 23 is illuminated. When the phase is about 27 degrees, the voltage is turned to a minimum value and flows through the second group of light-emitting diodes 230. 25 current is about -5_2mAe when the phase is 330 degrees to 360 degrees, the voltage is less than 90V 4 201034513 and greater than -90 V, at this time, the first group of LEDs 22 and the second group of LEDs 230 are turned off, Therefore, the current is 〇mA. As can be seen from Fig. 3, the first group of light-emitting diodes 22 and the second group of light-emitting diodes 230 are sometimes turned on and sometimes turned off. This causes flicker. And 5 produces unpleasantness. Therefore, the prior art as shown in Fig. 2 is not suitable for use in lighting facilities. Figure 4 is a schematic illustration of another conventional use of a light emitting diode. The working principle is similar to the conventional technique of Fig. 2, which uses a light-emitting diode as a rectifier. In the prior art of Fig. 4, the light-emitting diode still has a situation in which it is sometimes turned on and sometimes turned off, so that flickering still occurs. 5 and 6 are schematic views showing the use of another conventional light-emitting diode. As shown in FIG. 5, it is composed of an AC power source 2 1 〇, a group of LEDs 220 and a half-wave rectifier 240, and FIG. 6 is composed of an AC power source 21 〇 and a group of light-emitting diodes 220. And a full-wave rectifier consists of 250. Such a use of a series of LEDs plus a half-wave/full-wave rectifier only reduces the number of light-emitting diodes used, and still causes flicker problems. • Figures 7 and 8 are schematic views of another conventional use of a light-emitting diode. As shown in FIG. 7 , it is composed of an AC power source 210, a group of LEDs 220, a half-wave rectifier 240 and a filter capacitor 260, and FIG. 8 is composed of a 20-flow power source 210 and a group of two light-emitting diodes. The polar body 220, the full-wave rectifier is composed of 250 and the filter capacitor 260. The use of a series of light-emitting diodes plus a half-wave/full-wave rectifier plus a filter capacitor 260 results in a problem that the filter capacitor 260 is too large in harmonics and easily causes a charge pulse current, thereby causing a power factor. Low phenomenon. FIG. 9 is a schematic diagram of currents when the filter capacitor 25 740 is charged and discharged in FIG. 7 and FIG. 8 . As shown in FIG. 9 , when the filter capacitor 260 charges 201034513, a considerable charging pulse current is generated, which easily causes components of the AC power source 210 . Damage 'and contamination of the grid due to excessive harmonics. It can be seen from this that the driving technology of the conventional light-emitting diodes still has many defects and needs to be improved.

The second rectifying device 640 is preferably a rectifying diode. The input end 641 of the second rectifying device 640 is an anode of the rectifying diode, and the output end 642 is a φ cathode of the rectifying diode. The second group of LEDs 650 has a first electrode end 651 and a second electrode end 652, and the second electrode end 652 is connected to the output end 642 of the second rectifying device 640 and the first energy storage device. Second electrode end 632 of 630. The second group of light emitting diodes 650 is composed of a plurality of light emitting diodes, and the plurality of light emitting diode systems form the second group of 15 light emitting diodes 650 in series. The number of the second group of light-emitting diodes 650 is the same as the number of the first group of light-emitting diodes 620. The first electrode end 651 of the second group of LEDs 650 is the cathode of the light emitting diode, and the second electrode end 652 is the anode of the light emitting diode.

When the first rectifying device 610 does not generate the rectifying current, the second energy storage device 660 applies an discharging energy 25 for the second group of LEDs 650. 8 201034513 The light-emitting diode of the first group of light-emitting diodes 620 and the second group of light-emitting diodes (4) may be composed of a multi-micro crystal structure of a single light-emitting diode chip or a multi-chip package structure. Or a structure composed of a plurality of light-emitting diode chips. Fig. 11 is a view showing the waveform of the voltage current of the driving device 600 of the light-emitting diode of the present invention. It uses an AC power source 67〇. Fig. 12 and Fig. U are schematic diagrams showing the current of the driving device 6〇〇 of the light-emitting diode of the present invention. As shown in FIG. 11, at time t0, the voltage output from the AC power source 67 is greater than the voltage of the first energy storage device plus the voltage of the second energy storage device, so that the first group of light-emitting diodes is 10 to ~ ti 62〇 and the second group of LEDs 65〇 are turned on, and the first energy storage device 630 and the second energy storage device 66 are charged. As shown in Figure 12, there are three current paths. The current 〗 i flows through the first rectifying device 61 〇, the first group of LEDs 62 〇, the second rectifying device 640, and the second group of LEDs 65 分别 respectively. Current 12 flows through first full stream device 610, first energy storage device 630, and second group of light emitting diodes 650. The current π flows through the first rectifying device 6A, the first group of light emitting diodes 620, and the second energy storage device 66A. The current 12 and the current 13 charge the first energy storage device 630 and the second energy storage device 660, respectively. At time t1, the voltage output by the alternating current power source 670 is less than the voltage of the first energy storage device 20 plus the voltage of the second energy storage device, and the first rectifying device 610 is disconnected 'the first rectifying device 610 does not generate the rectified current. The first energy storage device 630 and the second energy storage device 660 apply discharge energy to the first group of light emitting diodes 620 and the second group of light emitting diodes 650. Therefore, the first energy storage device 630 and the second energy storage device 660 supply 25 electric energy at time t1 to t2, and the first group of light emitting diodes 620 and the second group of light emitting diodes 9 201034513 650 continue to emit light. There is no problem in the prior art that the light-emitting diode cannot emit light and cause flicker. As shown in FIG. 13, at time ti~t2, the first energy storage device 63 is supplied with electric energy, and the current flows from the first electrode end 631 of the first energy storage device 630 to 'flow through the first group of illuminations respectively. The diode 620 and the second rectifying device 64 are flowed into the second electrode end 632 of the first energy storage device 630. At the same time, the second energy storage device 660 also supplies electrical energy, and the current flows from the first electrode end 661 of the second energy storage device 660, respectively flowing through the second rectifying device 64A and the second group of LEDs 650'. The 10th second electrode end 662 of the second energy storage device 660 flows into the second energy storage device 660. At time t2, the voltage output by the AC power source 670 is greater than the voltage of the first energy storage device plus the voltage of the second energy storage device, so the above actions are repeated, and will not be described herein. Fig. 14 is a waveform measurement diagram of the voltage and electric current of the driving device 600 of the light-emitting diode of the present invention. As can be seen from FIG. 14, the current flowing through the first group of light-emitting diodes 620 and the second group of light-emitting diodes 650 is much larger than 〇A, so the first group of light-emitting diodes 620 and the group of light-emitting diodes 650 continue. Illumination, there will be no dark phenomenon, thus improving the problem of flicker. Fig. 15 is a view showing another embodiment of the driving device 6 of the light-emitting diode of the present invention. The waveform diagram of the voltage and current is easily derived by those skilled in the art based on the technique of the present invention, and will not be described herein. The main difference from Fig. 1 is that the first rectifying device 610 is a bridge rectifier. Fig. 16 is a view showing still another embodiment of the driving device 6 of the light-emitting diode of the present invention. The main difference from FIG. 10 is that the first group of light-emitting diodes 25 620 are formed by paralleling N sets of series light-emitting diodes, and the second group of light-emitting 10 201034513 diodes 650 are composed of N sets of series-connected light-emitting diodes. The body is connected in parallel (n is a positive integer). FIG. 17 is a schematic view showing still another embodiment of the driving device 60 of the light-emitting diode of the present invention. The main difference from FIG. 15 is that the first group of light-emitting diodes 620 are formed by paralleling N sets of series light-emitting diodes, and the second group of five-light diodes 650 are connected by N sets of series light-emitting diodes in parallel. Made (1^ is a positive integer). As apparent from the foregoing description, in the prior art, it is impossible to reduce the phenomenon of flashing of the light-emitting diode while maintaining a high power factor and reducing harmonics. The first energy storage device 030 and the second energy storage device 66 〇 10 use the first power storage device 030 and the second energy storage device 66 〇 10 to supply power when the voltage outputted by the driving power source is lower than the starting voltage, so that the light emitting diode continuously emits light, thereby eliminating the phenomenon that the light emitting diode generates flicker. In addition, the present technology can also be applied to LED backlights, displays, lamps, or solid state lighting fixtures. It can be seen from the above that the present invention is extremely useful in terms of its purpose, means, and efficacy, both of which are different from those of the prior art.
