New Description: [New Technology Field] This new type is related to the start-up circuit of an electronic ballast, especially a kind of DC electronic which has energy saving, good lighting stability and can extend the life of the lamp. The preheating start circuit of the ballast. [Prior Art] Discharge-type lighting fixtures, such as fluorescent tubes, fluorescent tubes, etc., and | can not directly connect directly with the power supply, and its operating voltage during normal operation is not enough to stimulate the discharge of gas, so It is necessary to connect a suitable ballast in series to assist the lamp start, and at the same time, after the lamp is started, the voltage of the two poles is limited and the discharge current is stabilized, so that the lamp can continue to emit light normally, and the illumination is on the conventional electromagnetic ballast. Compared with the electronic ballast, the main difference between the two is that the traditional electromagnetic ballast is a low-frequency (6〇Hz) lighting, while the electronic female is a light-emitting (20KHz~60KHz) lighting, electronic ballast Compared with the traditional electromagnetic female niece, it has large energy saving, stable illumination, no flickering, eye protection, high power factor, low audible noise, high safety, dimming, low maintenance cost, and long lamp life. · And many other advantages, the electronic ballast has become the primary consideration in the choice of use. According to the difference of the startup mode, the electronic ballast can be divided into the following three types: 1. Pre-heated start. With the fluorescent tube of the preheating start type electronic ballast, the two-pole filament must be pre-moderated before starting. Heating (at this time, there may be a weak illuminating phenomenon at both ends of the lamp 5 M3 07929), so that when starting, it helps the high voltage applied to the two ends of the lamp to generate a discharge arc between the two pole filaments, so that the lamp is smooth Start up and illuminate completely. The biggest feature of this type of electronic ballast is that the filament can be fully preheated, and no voltage or current is input into the filament after the lamp is lit. The number of times the lamp can be extinguished can be as high as about 2 million to 5 million times. Therefore, it is suitable for a place where the lamp switch has a high frequency of extinguishing, and can effectively suppress the blackening of the lamp (due to insufficient preheating of the filament, excessive consumption of sputtering after energization) and prolong its life. 2. Rapid Start (Rapid Start) With the fluorescent tube of the quick-start type electronic ballast, the two-pole filament is always maintained in the heating state with voltage and current input. Therefore, it is only necessary to warm up from a very short time to quickly complete the lighting. About 0.5 to 1 second 'the number of times it is off is about 12,000 to 15,000 times. Therefore, such a neon tube is suitable for use in a low temperature region, but it consumes a large amount of electricity and is prone to blackening. Second, instant start (Instant Start). The fluorescent tube used with the instant start type electronic ballast does not need to pass through the filament preheating stage before starting, and is directly connected to the high voltage (between 800V and l, 2〇〇v) to start the lamp, and the point is extinguished. The number is only about 2,000 to 3 times. Therefore, such a fluorescent tube is quite prone to filament breakage, blackening of the lamp, etc., and the price is relatively low, and it is suitable for use in places where the number of switching points is not frequent. M3 07929 [The new content j ^^strict and the purpose of the type] is to provide a kind of DC electronic ballast for the portable photo and greatly save the power consumption of the lamp, improve the lighting quality of the lamp and extend the service life of the lamp. Circuit. Therefore, the preheating start circuit of the novel DC electronic ballast is connected to:: a DC power source capable of outputting alternating current dust and - between the lamps. The startup circuit includes a power-frequency virtual unit connected to the DC power source, a detection protection unit electrically connected to the illumination lamp, and a = lamp unit. The high-frequency oscillating unit can convert the DC power supply voltage oscillation into a voltage output, and a part of the AC voltage is used to preheat the two filaments of the illumination lamp, and ^ The resistance of the -k wire is raised to a steady state value. The detection protection unit has a voltage for detecting the resistance change of the two filaments, the polar body, and the abusive network, 曰乂And a protective device that controls the actuation of the 压% voltage diode: the 曰 body, when the steady-state resistance value of the two filaments is measured by the stabilizing diode, the protective transistor is alternately turned on, and when the stagnation is stabilized The voltage diode is not in the Γ: "When the steady-state resistance of the filament is used, the two protection transistors are controlled. 4 A knife is not electrically connected to the high-frequency oscillation sheet: k 4 starts the electric solar body, in the second When the protection transistor is alternately electrically connected to form a loop, it can control the two start-up transistors corresponding to alternating lead wires so that the AC voltage output by the 1 Hz high-frequency vibration unit can be input to the two lamps, and 糸' is started by rolling The light of the present invention is that the power source is to be used for the purpose of Light lamp = before use 'Through the _ protection unit of the stable factory Jian Er 2 physical energy bond to test whether the two filaments of the photo r have been preheated. After confirming that the filament preheating is completed, M307929 the voltage regulator diode controls the second The protection transistor is triggered to form a loop, so that a high-frequency alternating voltage is alternately applied to the two filaments, so that the illumination lamp can be activated and illuminated, thereby suppressing blackening of the lamp and making the lamp energy-saving and energy-saving. The above-mentioned and other technical contents, features and effects of the present invention will be clarified in the following detailed description of a preferred embodiment with reference to the drawings. As shown in FIG. 1 , the preferred embodiment of the preheating start circuit 2 of the novel DC electronic ballast is electrically connected to a DC power source 1 (such as a battery) capable of outputting a DC voltage, and an illumination lamp. Between the three. The illuminator 3 is a person who activates the illuminator through a gas discharge mechanism, such as a high pressure mercury lamp, a metal halide lamp, a low pressure sodium lamp, and a high pressure sodium lamp, etc. In the embodiment, the illuminating lamp 3 is a general straight tubular fluorescent lamp having a filament 31 (that is, a positive coefficient type temperature sensible resistor) at both ends thereof; as for the gas discharge illuminator of the illuminating lamp 3, the technical field is It has a well-known technology and is beyond the scope of protection of the present invention, and will not be described in detail herein. The child preheating start circuit 2 includes a high frequency oscillating unit 21 electrically connected to the DC power source 、, a detecting and protecting unit 22 for connecting the two filaments 31 of the illuminating lamp 3, and a lighting unit 23 electrically connecting the high-frequency oscillating unit 21 and the two filaments 31 of the illuminating lamp 3. The high-frequency oscillating unit 21 can The DC voltage provided by the DC power supply is rectified and oscillated into a high-frequency AC voltage (such as 6〇KHz) and outputted. The AC voltage of the DC power supply is first input via the bypass via the two filaments. M307929 'heat' causes the resistance of the two filaments 31 to increase with increasing temperature until the resistance of the two filaments 3! rises to a steady state value (about 6 for preheating). The detection and protection unit 22 has a voltage-receiving diode Z for detecting the resistance change of the two filaments 3 1 on the top of the field, and the voltage-regulating diode Body protection control actuated protective transistors TR1, TR2; Tai Λ, jujube μ example, the voltage regulator diode
Ζ為稽納二極體（Ziner)。當該穩壓二極體Ζ測知該二燈絲 31已預熱達該穩態電阻值時，則控制該二保護電晶體tri 、TR2呈父替導通/截止；當該穩壓二極體z測知該二燈絲 31未完成預熱而未達該穩態電阻值時，則控制該二保護電 晶體TR1、TR2皆呈截止狀態。 該點燈單元23具有二分別電連接該高頻振盪單元21 與該二燈絲、31的啟動電晶體Q1、Q2。於該偵測保護單元 22之二保護電晶體TR1、TR2呈交替導通/截止時（即該二 燈絲31已預熱完成），能控制該二啟動電晶體Q1、對應 呈交替觸發並構成迴路，使得該高頻振盪單元21所輸出之 交流電壓能輸入至該二燈絲31，藉由施加於該二燈絲31之 瞬間高壓效應，以激發氣體放電過程，而啟動該照明燈3。 請配合如圖2所示，於該照明燈3啟動前，必先經過 約1秒的預熱階段，亦即，該直流電源丨開始通電時，該 照明燈3並不會馬上點亮。此時，該直流電源丨之直流電 壓會先經该南頻振盪單元21整流、振盪成高頻交流電壓， 部分交流電壓會對該照明燈3之二燈絲3 1進行預熱。It is the Zener. When the voltage regulator diode detects that the two filaments 31 have been preheated to the steady state resistance value, the two protection transistors tri and TR2 are controlled to be turned on/off; when the voltage regulator diode z When it is determined that the two filaments 31 have not completed the preheating and the steady state resistance value is not reached, the two protection transistors TR1 and TR2 are controlled to be in an off state. The lighting unit 23 has two starting transistors Q1 and Q2 electrically connected to the high frequency oscillating unit 21 and the two filaments 31, respectively. When the two protection transistors TR1 and TR2 of the detecting and protecting unit 22 are alternately turned on/off (that is, the two filaments 31 are preheated), the two starting transistors Q1 can be controlled to alternately trigger and form a loop. The AC voltage outputted by the high frequency oscillating unit 21 can be input to the two filaments 31, and the illuminating process is activated by the high voltage effect applied to the two filaments 31 to activate the illuminating lamp 3. Please cooperate with the preheating stage of about 1 second before starting the illumination lamp 3, that is, the illumination lamp 3 will not light up immediately when the DC power supply starts to be energized. At this time, the DC voltage of the DC power source is first rectified by the south frequency oscillation unit 21 and oscillated into a high-frequency AC voltage, and part of the AC voltage preheats the filament 3 of the illumination lamp 3.
當該偵測保護單元22之穩壓二極體Z測知該二燈絲3 J 9 M307929 已確貝預熱完成時，便控制該二保護電晶體TR1、TR2呈交 替導通/截止，進而控制該點燈單元Μ之啟動電晶體qi、 Q2對應呈交替觸發作動而構成迴路。此時，因該高頻振盪 皁兀21感應到迴路變化，從而能將高頻交流電壓施加於該 照明燈3兩端的該二燈絲31，迅速激發該照明燈3内之氣 體放電釋光過程，便完成該照明燈3之啟動。一旦該照明 燈3啟動而開始發光後，該直流電源1之直流電壓便能交 替輸入該二燈絲31，使該二燈絲31輪流消耗以釋出電子並 形成放電電弧，該照明燈3便能進行發光、照明。 同時，该偵測保護單元22仍會持續偵測該二燈絲3 i 之電阻值是否異常、限制該二燈絲31之電壓變化，並穩定 孩一燈絲31間的放電電流··，藉以使該照明燈3能安全、 穩定地發光。 因此’遠直流電子安定器之預熱啟動電路2於實際使 用時，由於是透過該高頻振盪單元21將直流電壓轉換成高 頻父流電壓’以高頻交流電壓進行點燈，故而能大幅節省 該照明燈3之耗電，且其所輸出光波穩定不易閃爍，有助 於保濩視力並提昇照明品質；再者，透過該偵測保護單元 22能於辟保燈絲31確實預熱完成後，始供予高壓而進行啟 動’能有效抑制燈絲3 1過度損耗濺射，避免照明燈3產生 黑化現象’以延長其使用壽命；特別是，是以直流電源1( 如蓄電池）作供電，使該照明燈3適用於隨身攜帶以易地使 用。 歸納上述’本新型直流安定器之預熱啟動電路2，利用 10 M3 07929 该咼頻振盪單元21將直流電壓轉換成高頻交流電壓，並配 合该偵測保護單元22能確保燈絲31已預熱完成，高頻交 電壓始旎加壓予燈絲3 1以進行點燈，藉以使該照明燈3 具有便於攜帶使用、大幅節能省電、照明品質佳與使用壽 命長等功效，故確實能達到本新型之目的。 准以上所述者，僅為本新型之較佳實施例而已，當不 能以此限定本新型實施之範圍，即大凡依本新型中請專利 範圍及新型說明内容所作之簡單的等效變化與修飾，皆仍 屬本新型專利涵蓋之範圍内。 【圖式簡單說明】 子安定器之預熱 直流電源與一照 圖1是一電路圖，說明本新型直流電 啟動電路的一較佳實施例，是電連接於一 明燈之間；以及 、 圖2是忒較佳實施例之一作動流程圖。 M307929 【主要元件符號說明】 1 直流電源 2 直流電子安定器之預熱啟動電路 21 高頻振盪單元 22 偵測保護單元 Z 穩壓二極體 TR1、TR2 保護電晶體 23 點燈單元 Ql、Q2 啟動電晶體 3 照明燈 31 燈絲When the voltage stabilizing diode Z of the detecting and protecting unit 22 detects that the two filaments 3 J 9 M307929 have been preheated, the two protective transistors TR1 and TR2 are alternately turned on/off, thereby controlling the The starting transistors qi and Q2 of the lighting unit 对应 are alternately triggered to form a loop. At this time, since the high frequency oscillating sapon 21 induces a loop change, a high frequency alternating current voltage can be applied to the two filaments 31 at both ends of the illuminating lamp 3, and the gas discharge luminescence process in the illuminating lamp 3 is quickly excited. The activation of the illuminator 3 is completed. Once the illumination lamp 3 is activated and starts to emit light, the DC voltage of the DC power source 1 can be alternately input to the two filaments 31, so that the two filaments 31 are consumed in turn to release electrons and form a discharge arc, and the illumination lamp 3 can be performed. Lighting, lighting. At the same time, the detection and protection unit 22 still continuously detects whether the resistance value of the two filaments 3 i is abnormal, limits the voltage change of the two filaments 31, and stabilizes the discharge current between the filaments 31, thereby enabling the illumination. The lamp 3 can emit light safely and stably. Therefore, when the preheating start circuit 2 of the far-current electronic ballast is turned on by the high-frequency oscillating unit 21 to convert the DC voltage into a high-frequency parent-current voltage, the high-frequency AC voltage is used for lighting. The power consumption of the illumination lamp 3 is saved, and the output light wave is stable and not easy to flicker, which helps to maintain vision and improve the illumination quality. Moreover, after the detection protection unit 22 can ensure that the filament 31 is indeed warmed up, Starting to supply high voltage to start 'can effectively suppress filament 3 1 excessive loss of sputtering, to avoid blackening phenomenon of lighting 3' to prolong its service life; in particular, it is powered by DC power supply 1 (such as battery), so that The light 3 is suitable for carrying around for easy use. The preheating start circuit 2 of the above-mentioned DC stabilizer is summarized, and the DC voltage is converted into a high-frequency AC voltage by using the 10 M3 07929, and the detection protection unit 22 can ensure that the filament 31 is warmed up.
