X and use [Prior Art] Fluorescent lamps commonly used in daily life, such as the first and second figures. The fluorescent lamp 10 mainly includes a lampshade 12 and at least one fluorescent lamp lamp 15 and a fluorescent lamp cover. ·古^ _ „ Lamps 12 on the 5 and a turbulent power supply (or power supply. Power plug, AC power U and then connected - ballast (or, 疋, calmer) 13 'the two sides of the lampshade 12 Each of the lamp holders 17 is provided with two sockets 175, and one of the sockets 175 is electrically connected to the ballast η. The first pin 155 and the second pin 156 'the first pin 155 and the second pin 156 can be inserted into the jack 175 to reach the fixed fluorescent lamp tube 15. One of the first pins 155 is: Electrically connected to the ballast 13 while the first pin 155 of the other end is The AC power supply 11 is connected, and the second pins 156 at the two ends are respectively connected to the two ends of the starter 19, thereby forming a complete fluorescent lamp driving circuit 2〇. Corresponding to the second connection 155 and the second pin 156 A filament 151, 153 is connected to the lamp tube 15. When the filament 15 in the lamp tube 15 is heated by the AC power source U and emits electrons, the fluorescent lamp 15 can generate a light source. Light-Emi tt ing Diode is widely used in indications because of its long life, small size, low power consumption, fast response, no radiation and monochromatic illumination. Lights, advertising billboards, traffic lights, car lights, display panels, communication equipment, consumer electronics, etc. Among them, light-emitting elements that can produce white light sources can be used to replace traditional incandescent or fluorescent tubes. And become a new generation of lighting source's and thus more popular with the world. The light-emitting diode itself is a very sensitive component of the voltage, when the excessive voltage is input into the light-emitting diode, it will Excessive current is formed on the light-emitting diode, which may cause damage of the light-emitting diode. Therefore, when using the light-emitting diode, it is often necessary to adjust the power supply voltage according to the type of the light-emitting diode and the number of series connection. The size and supply of the appropriate driving voltage to the light-emitting diode. In general, the voltage value of the power supply voltage tends to be greater than the actual driving voltage value of the light-emitting diode'. Therefore, the power supply voltage needs to be further reduced during use. The step of pressing. For example, the LED can be connected in series with an appropriately sized resistor, and the supply voltage will form a load on the resistor, thereby reducing the supply voltage and providing appropriate illumination dipoles. Drive voltage. Although the setting of the resistor can effectively reduce the size of the power supply voltage, the resistor is a component that consumes power. In other words, although the resistor can cause a drop in power, it also causes loss of energy, and it is contrary to the use of the light-emitting diode. The body carries out the purpose of energy saving. Of course, it is also possible to use a transformer to transform the supply voltage, thereby generating a suitable driving voltage of 201102558. Compared with the resistor, the transformer can complete the step-down operation without consuming too much energy. The transformer itself has a complicated structure and a large volume, so it is not suitable for a small-sized light-emitting device. In addition, the production cost of the variable m is higher, and the production cost of the product is not. _ [Summary of the Invention] The main purpose of this month is to provide a light-emitting diode lamp, which can directly use the fluorescent lamp cover as the lamp cover of the light-emitting diode lamp, and utilize the ballast of the fluorescent lamp as the light-emitting diode The body drive circuit must use the inductor to enhance the acceptance and usage rate of the consumer using the LED lamp.

The side end of the illuminator is connected, and one of the first pins is connected to the damper. There is a whole between Ms. and Zang Zanyou: a lamp for a light-emitting diode f base.

And a power processor includes an inductor and a second: 201102558, the inductor is electrically connected to the rectifier, and the inductor is disposed in the copper head, in the base or outside the light emitting diode bulb, and the rectifier is disposed on the The inside of the copper head, the pedestal or the light-emitting diode bulb, and the power processor will be electrically connected to the light-emitting diode. The present invention further provides a driving circuit for a light emitting diode, comprising: an inductor capable of connecting an AC power source, and the AC power source generates an AC voltage, and the S-father current voltage forms a load on the inductor, and The AC voltage is stepped down by the inductor; a rectifier is connected to the inductor, and is used to rectify the depressurized AC voltage to generate a DC voltage; and at least one LED is connected to the rectifier' The light emitting diode is driven by the DC voltage. The invention further provides a driving circuit for a light emitting diode, comprising: a rectifier capable of connecting an AC power source and rectifying an AC voltage generated by the AC power source to generate a DC voltage; an inductor, connecting In the rectifier, the DC voltage forms a load on the inductor, and the DC voltage is stepped down by the inductor; and at least one LED, the LED is connected to the inductor and the step-down DC The light is driven by the light emitting diode. [Embodiment] Please refer to FIG. 3 and FIG. 4, which are respectively a block diagram and a circuit diagram of an embodiment of a driving circuit of a light-emitting diode of the present invention. As shown in the figure, the driving circuit 30 includes an AC power source 31, an inductor 33, a rectifier 35, and at least one light emitting diode (LED) 37. The inductor 33 and the rectifier 35 7 201102558 are further disposed to emit light. The one body 37 provides a suitable driving voltage v and drives the light-emitting diode 37. The AC power supply 31 is a power supply for the LEDs 37 and is used to generate an AC voltage Vs. Generally, the AC voltage Vs generated by the AC power source 31 is not an appropriate driving power source for the LEDs 37. Therefore, it is necessary to rectify the AC voltage Vs generated by the AC power source 31. In the present invention, the rectifier 35 is mainly connected to the AC power source 3, and the AC voltage Vs generated by the AC power source 31 is trimmed by the rectifier 35 to generate a DC voltage, and the DC voltage Vd can be driven. Light-emitting diode 37. For example, rectifier 35 can be a bridge rectifier ' and includes a plurality of diodes as shown in FIG. An inductor 33 may be added between the parent current source 31 and the rectifier 35. The AC current I s formed by the carrier voltage Vs will form a load on the inductor 33 after passing through the inductor 33, thereby generating an AC power source 31. The AC voltage Vs is stepped down. For example, the AC voltage vs. forms a load voltage V1 on the inductor 33. By the formation of the load voltage vL, the AC voltage Vs can be stepped down, and the stepped AC voltage Vs is rectified. An appropriate magnitude of the driving voltage v is formed on the body 37. In general, the relationship between the inductor 33 and the load voltage V1 formed on the inductor 33 is as follows:
Vl=L (di/dt) 由上式可知電感33上之負載電壓Vl的大小正比於電感33 的電感值L。換言之，在應用時可以透過電感33之電感值 L的選擇’來改變電感33上所形成的負載電壓vL。對本發 201102558 明來說，可以由交流電源31所產生的交流電壓Vs及發光 二極體37所需要的驅動電壓v來選擇適當電感值l的電感 33,並在電感33上形成適當大小的負載電壓vL，藉此將可 以提供適當大小的驅動電壓V給發光二極體37。 將電感33應用在發光二極體37之驅動電路30時，除 了可以選擇適當之電感值L的電感33對交流電壓Vs進行 降壓之外’亦可以減少在降壓過程當中電感33對交流電源 31所產生的電能所造成過多的損耗。 • 交流電源31所產生的交流電壓Vs會在電感33上形成 交流電流Is ’交流電流is在通過電感33時，電感33會 阻礙交流電流Is的變化，例如當交流電流Is增加時電感 33會阻礙交流電流is的增加，而當交流電流Is減小時電 感33則會阻礙交流電流is的減小。因此以電感⑽上所形 成的負載電壓Vl對交流電壓Vs進行壓降時將不會對能量 造成過多的損失。相較之下電阻是以消耗能量的方式進行 降壓的動作，因此在使用的過程當中會造成額外的能量損 •失。 電感33在阻礙交流電流Is變化的過程當中並不會對 能量造成損耗，以在交流電流13增加的同時以磁場的方 式暫時將電能進行儲存，在交流電流Is減小時電感犯上 之磁場的能量會被進—步釋放出來。因此電感33對驅動電 路30而言，更具有穩定驅動電壓v的作用，並有利於穩定 發光極體37所產生之光源的亮度。此外，在實際應用時 交流電源31亦可為一 PFC電源（p〇wer 201102558Vl=L (di/dt) From the above equation, it is known that the magnitude of the load voltage V1 on the inductor 33 is proportional to the inductance L of the inductor 33. In other words, the load voltage vL formed on the inductor 33 can be changed by the selection of the inductance value L of the inductor 33 during application. For the present invention, the inductance 33 of the appropriate inductance value 1 can be selected from the AC voltage Vs generated by the AC power source 31 and the driving voltage v required by the LEDs 37, and an appropriate size load is formed on the inductor 33. The voltage vL, by which a suitable driving voltage V of the magnitude can be supplied to the light-emitting diode 37. When the inductor 33 is applied to the driving circuit 30 of the light-emitting diode 37, in addition to selecting an appropriate inductance L of the inductor 33 to step down the AC voltage Vs, the inductor 33 can be reduced in the step-down process. The electrical energy generated by 31 causes excessive losses. • The AC voltage Vs generated by the AC power source 31 forms an AC current Is on the inductor 33. When the AC current is passed through the inductor 33, the inductor 33 blocks the change of the AC current Is. For example, when the AC current Is increases, the inductor 33 blocks. The increase in the alternating current is, and the inductance 33 hinders the decrease in the alternating current is when the alternating current Is decreases. Therefore, the voltage drop of the AC voltage Vs with the load voltage V1 formed on the inductor (10) will not cause excessive loss of energy. In contrast, the resistor is a step-down action that consumes energy, so it causes additional energy loss and loss during use. The inductor 33 does not cause loss of energy during the process of obstructing the change of the alternating current Is, so as to temporarily store the electric energy by the magnetic field while the alternating current 13 increases, and the energy of the magnetic field of the inductance when the alternating current Is decreases It is released in steps. Therefore, the inductor 33 has a function of stabilizing the driving voltage v for the driving circuit 30, and is advantageous for stabilizing the brightness of the light source generated by the light-emitting body 37. In addition, the AC power supply 31 can also be a PFC power supply in practical applications (p〇wer 201102558)

’如同習用之日光燈燈罩（11)一般，LED燈 罩22上設有一交流電源（或稱電源開關、電源插頭）51，交 流電源51再連接有一安定器（或稱穩定器、鎮定器）53，燈_ 罩52之兩側端個別設有一燈管固定架，每一個燈管固 定架57上設有至少一個插孔575，一般係以兩個插孔575 為佳。其中一燈管固定架57之其中一插孔575將電性連接 安定器53,如第1 1圖所示之上側端。而另一燈管固定架 57之其中一插孔575則連接交流電源5卜如第丄丄圖所示 之下側端。 LED燈管55具有一基座551，基座551之表面設有至 少一個發光二極體553,而基座551之兩端則個別設有一 φ 接腳，例如本實施例所示之兩個接腳：第一接腳555及一 第一接腳556，兩端之第一接腳555將電性連接發光二極 體553。其中一個第一接腳555與發光二極體553之間尚 設有一整流器54。 基座551上之發光二極體553可為一包括有複數個發 光一極體553之LED燈串為較佳，每一個發光二極體553 之間可以用串聯、並聯或串聯/並聯方式連接，其中一最側 12 201102558 端之發光二極體553可連接相對應之第一接腳555，而另 一最側端之發光二極體553則經由整流器54以連接相對應 之第一接腳555，藉此以形成LED燈管55之驅動電路。 本發明之LED燈管55為了要形成與一般日光燈燈管 (15)相同之外形構造，因此在LED燈管55之兩端設有第一 接腳555及第二接腳556。但其實只需要第一接腳555或 第二接腳556之其中一支接腳與發光二極體553連接即 可，例如此圖式中係以第一接腳555與發光二極體553電 • 性連接，而第二接腳556則藉由一連接線路557與第一接 腳555電性連接。 當第一接腳555及第二接腳556插合於插孔575内 時，除了可達到固定LED燈管55之目的外，亦可同時完成 LED燈具50及其驅動電路60之連接工作。 如果第一接腳555剛好插合於連接安定器53或交流電 源51之插孔5 7 5，則交流電源51、安定器5 3、插孔5 7 5、 第一接腳555、整流器54、發光二極體553、第一接腳555、 插孔575、交流電源51，以形成一完成之電路迴路，並致 使發光二極體553產生光源。 如果是第二接腳556剛好插合於連接安定器53或交流 電源51之插孔5 7 5，則交流電源51、安定器5 3、插孔5 7 5、 第二接腳556、連接線路557、第一接腳555、整流器54、 發光二極體553、第一接腳555、連接線路557、第二接腳 5 5 6、插孔5 7 5、交流電源51，同樣可形成一完成之電路迴 路，並致使發光二極體553產生光源。 13 201102558 由於燈具50係連接一交流電源51，因此具有整流器 54之LED燈管55侧端係插合於與安定器53連接之上侧端 插孔575、或是與交流電源51連接之下側端插孔575，都 不影響電路迴路之完成。 又，本發明為了達到LED燈罩22之電路及外形構造與 一般日光燈燈罩（11)近似之目的，另外可於LED燈罩52上 設有一啟動器59，啟動器59之兩端分別連接兩端燈管固 定架57未連接安定器53/交流電源51之插孔575,如第1 1圖所示之右邊插孔575。 當LED燈罩54係連接一傳統LED燈管55時，啟動器 59並不影響發光二極體553之動作。但如果LED燈罩54 係連接一日光燈燈管（15)時，則此啟動器59就可作為等待 燈絲（151)加熱放電以產生光源之電路元件。 由於現在市售之具有電子式安定器（Electronic ballast)的日光燈燈具已經可達到免用啟動器之功能，因 此，本發明LED燈罩52即便沒有啟動器59之設計，亦可 同時適用於LED燈管55及日光燈燈管（15)，以達到善用燈 罩資源及降低燈具製作成本之目的。 由於燈罩52之安定器53 —般係為電感元件，符合本 發明驅動電路60所需要之電感，因此本發明驅動電路60 之電感可直接沿用LED燈罩52或日光燈燈罩（12)上之安定 器53。 另外，請參閱第1 2圖，係本發明又一實施例之驅動 電路示意圖，本發明之整流器54除了可放在LED燈管55 201102558 内外，亦可設計在交流電源51與安定器53之間，或安定 器53與插孔575之間，藉此同樣可達到轉換交流電流以成 為一可供發光二極體553使用之直流電流。 又，第二插腳556亦可直接連接第一插腳555，而不 需要如前實施例所述需經過一連接線路（557)。 又，本發明之第一接腳555與第二接腳556亦可直接 連接發光二極體553之側端，但由於整流器54係固定於 LED燈管55之外，為避免發光二極體553之極性與所提供 籲之直流電源極性不同而造成發光二極體553之損壞，因 此，在第一插腳555 /第二接腳556與發光二極體553之間 可設有一二極體559，藉此以控制輸入發光二極體553之 直流電源方向性。 雖然在此圖式中，只有在上側之第一插腳555及第二 插腳556設有二極體559，但在不同實施例中，其底端之 第一接腳555/第二接腳556同樣也可個別設有一二極體 (559)，只要其二極體（559)設置方向要搭配發光二極體553 之電極方向性即可。換言之，如圖式之上側端、下側端或 兩侧端之第一接腳555第二接腳556設有二極體559都為 可行之實施例，而此發光二極體553與二極體559之極性 搭配必要性係為熟習電子電路者所能暸解者，在此不再贅 述。 請參閱第1 3圖，係本發明又一實施例之構造分解 圖，為了要降低消費者使用LED燈管55之陌生感與疑慮， 在此實施例中，LED燈管55之外圍可包覆有一外罩體558, 15 201102558 外罩體558係可由一透光材質或 以包覆發光二極體553。 透明材質所製成者。 如果外罩體558係為-圓柱管體或一長條狀之圓柱管 體如第1

addition to the step-down of the voltage step, and the energy loss caused by the step-down process can be reduced. The AC voltage Vs generated by the AC power source 31 will form a DC voltage Vd after passing through the rectifier 35, and the DC voltage will form a DC current h on the inductor 33. When the DC current lD passes through the inductor 33, the inductance will hinder the DC current ID. The change. In contrast, resistors are depressurized in a manner that consumes energy, and therefore cause additional energy loss during use. In the process of blocking the change of the direct current Id, the inductor 33 does not lose the amount of U*, and the electric current is stored in the magnetic field while the DC current Id increases. When the direct current h decreases. The energy of the magnetic field that the inductor makes is further released. Further, the inductor 33 thus has a function of stabilizing the driving voltage v for the light-emitting diode 37, and is advantageous for stabilizing the luminance of the light source generated by the light-emitting diode 37. This lx Ming mainly uses the component characteristics of the light-emitting diode to design a matching drive circuit, which is mainly used for the simplest component combination. 11 201102558 can achieve the steps of rectifying and stepping down the AC power, not only The advantages of reducing the size of the driving circuit and reducing the manufacturing cost are also sufficient for driving the light-emitting diode. For the continuation, please refer to the first and second figures, which are schematic exploded view of the embodiment of the lamp of the present invention and a schematic diagram of the driving circuit. The LED device 50 of the present invention mainly comprises a lampshade 22 and at least one LED lamp 55'. As is conventionally used in a fluorescent lampshade (11), an LED power supply is provided on the LED lampshade 22 ( Or the power switch, the power plug) 51, the AC power source 51 is further connected with a ballast (or stabilizer, calmer) 53, and the lamp _ cover 52 is separately provided with a lamp holder on each side of the cover 52, and each lamp tube is fixed The frame 57 is provided with at least one jack 575, and generally two jacks 575 are preferred. One of the jacks 575 of one of the lamp holders 57 is electrically connected to the ballast 53, such as the upper side end shown in FIG. One of the jacks 575 of the other lamp holder 57 is connected to the AC power source 5 as shown in the lower side of the figure. The LED tube 55 has a base 551. The surface of the base 551 is provided with at least one light-emitting diode 553, and the two ends of the base 551 are individually provided with a φ pin, for example, two connections as shown in this embodiment. The first pin 555 and the first pin 556 are electrically connected to the LED 553. A rectifier 54 is disposed between the first pin 555 and the LED 553. The LED 553 on the pedestal 551 can be a LED string including a plurality of illuminating poles 553. Each of the LEDs 553 can be connected in series, in parallel or in series/parallel. The light emitting diode 553 of one of the most side 12 201102558 terminals may be connected to the corresponding first pin 555, and the other side of the light emitting diode 553 is connected to the corresponding first pin via the rectifier 54. 555, thereby forming a driving circuit for the LED lamp 55. In order to form the same outer shape as the general fluorescent lamp tube (15), the LED lamp tube 55 of the present invention is provided with a first pin 555 and a second pin 556 at both ends of the LED lamp tube 55. However, only one of the first pin 555 or the second pin 556 needs to be connected to the LED 553. For example, in this figure, the first pin 555 and the LED 553 are electrically connected. • The second pin 556 is electrically connected to the first pin 555 via a connection line 557. When the first pin 555 and the second pin 556 are inserted into the jack 575, in addition to the purpose of fixing the LED tube 55, the connection work of the LED lamp 50 and its driving circuit 60 can be completed at the same time. If the first pin 555 is just inserted into the jack 5 75 of the ballast 53 or the AC power source 51, the AC power source 51, the ballast 5 3, the jack 5 7 5, the first pin 555, the rectifier 54, The light-emitting diode 553, the first pin 555, the jack 575, and the AC power source 51 form a completed circuit loop and cause the light-emitting diode 553 to generate a light source. If the second pin 556 is just inserted into the socket 5 7 5 of the connection ballast 53 or the AC power source 51, the AC power source 51, the ballast 5 3, the jack 5 7 5, the second pin 556, and the connection line 557, the first pin 555, the rectifier 54, the light-emitting diode 553, the first pin 555, the connection line 557, the second pin 5 5 6 , the jack 5 7 5, the AC power supply 51, can also form a complete The circuit loops and causes the light emitting diode 553 to generate a light source. 13 201102558 Since the lamp 50 is connected to an AC power source 51, the LED lamp 55 side end having the rectifier 54 is inserted into the side end jack 575 connected to the ballast 53 or the lower side connected to the AC power source 51. End jack 575 does not affect the completion of the circuit loop. In addition, in order to achieve the purpose of the circuit and the outer shape of the LED lamp cover 22 and the general fluorescent lamp cover (11), the LED lamp cover 52 can be provided with a starter 59, and the two ends of the starter 59 are respectively connected to the two ends of the lamp tube. The holder 57 is not connected to the socket 575 of the ballast 53/AC power source 51, such as the right side socket 575 shown in FIG. When the LED lamp cover 54 is connected to a conventional LED lamp 55, the actuator 59 does not affect the action of the light-emitting diode 553. However, if the LED lamp cover 54 is connected to a fluorescent lamp tube (15), the actuator 59 can serve as a circuit component for waiting for the filament (151) to be heated and discharged to generate a light source. Since the commercially available fluorescent lamp luminaire with electronic ballast can already achieve the function of the free starter, the LED lamp cover 52 of the present invention can be applied to the LED lamp tube at the same time even without the design of the starter 59. 55 and fluorescent tube (15), in order to make good use of the lampshade resources and reduce the cost of lighting production. Since the ballast 52 of the lamp cover 52 is generally an inductive component, which is in accordance with the inductance required by the driving circuit 60 of the present invention, the inductance of the driving circuit 60 of the present invention can directly follow the stabilizer 53 of the LED lamp cover 52 or the fluorescent lamp cover (12). . In addition, referring to FIG. 2, which is a schematic diagram of a driving circuit according to another embodiment of the present invention, the rectifier 54 of the present invention can be disposed between the AC power source 51 and the ballast 53 in addition to the LED lamp 55 201102558. , or between the ballast 53 and the jack 575, thereby also converting the alternating current to become a direct current for the light-emitting diode 553. Moreover, the second pin 556 can also be directly connected to the first pin 555 without passing through a connection line (557) as described in the previous embodiment. Moreover, the first pin 555 and the second pin 556 of the present invention can also be directly connected to the side end of the light-emitting diode 553, but since the rectifier 54 is fixed outside the LED lamp tube 55, in order to avoid the light-emitting diode 553 The polarity of the DC power source is different from the polarity of the DC power source provided, so that the LED 553 is damaged. Therefore, a diode 559 can be disposed between the first pin 555 / the second pin 556 and the LED 553. Thereby, the direct current power directivity of the input light-emitting diode 553 is controlled. Although in this figure, only the first pin 555 and the second pin 556 on the upper side are provided with the diode 559, in different embodiments, the first pin 555 / the second pin 556 at the bottom end thereof are also the same A diode (559) may be separately provided as long as the diode (559) is disposed in the direction of the electrode orientation of the light-emitting diode 553. In other words, the first pin 555 and the second pin 556 of the upper side or the lower side of the figure are provided with a diode 559, and the LED 553 and the diode are feasible. The polarity of the body 559 is necessary for those who are familiar with electronic circuits, and will not be described here. Referring to FIG. 13 , which is an exploded view of another embodiment of the present invention, in order to reduce the strangeness and doubt of the consumer using the LED tube 55 , in this embodiment, the periphery of the LED tube 55 can be covered. There is a cover body 558, 15 201102558 The outer cover body 558 can be made of a light transmissive material or to cover the light emitting diode 553. Made of transparent material. If the outer cover body 558 is a cylindrical tube body or a long cylindrical tube body as shown in the left side diagram of FIG. 4 , the LED tube 55 is completely identical in appearance to the general fluorescent lamp (15). The same, in order to increase the acceptance of the use of consumer purchases. The outer cover body 5581 may also be a half-cylindrical tube body or a long-length semi-cylindrical s body, as shown in the right side diagram of FIG. If the LED lamp 55 is a cover body 5581 which is half-shaped in the shape of a cylindrical tube, the surface of the light-emitting diode 553 is provided with a heat dissipation layer which can be conveniently arranged; Further, a color changing layer 759, such as a phosphor layer or the like, may be disposed in or on the outer cover body 558/5581 to change the color of the light emitting diode 553 or adjust it to a white light source. Of course, in the spirit of the invention, the LED tube 55 and the outer cover 558 can also be designed as a circular structure. More precisely, [the rib tube is a π-concentric semi-cylindrical tube, and As a conventional circular fluorescent lamp, φ can also have the technical features required for the LED lamp of the present invention. If the LED tube 55 is a concentric semi-cylindrical tube, the lamp cover 52 only needs a lamp holder 57' and the tube holder 57 will be provided with a plurality of jacks 575' to facilitate the first pin 555. And/or the second pin 556 is inserted and used.
