Description

この発明は、例えば蛍光灯についている保安球を点灯させる保安球点灯装置に関する。   The present invention relates to a safety ball lighting device that lights a safety ball mounted on a fluorescent lamp, for example.

従来から、リモコン送信機の操作によって蛍光灯や保安球を点灯させる蛍光灯照明装置が知られている（特許文献１参照）。   2. Description of the Related Art Conventionally, a fluorescent lamp illumination device that lights a fluorescent lamp or a safety bulb by operating a remote control transmitter is known (see Patent Document 1).

かかる蛍光灯照明装置は、リモコン送信機からの信号を受ける制御回路と、この制御回路からの信号に基づいて放電灯や保安球を点灯させる放電灯点灯装置とを備えている。
特開２００６−１２７５０号公報 Such a fluorescent lamp illumination device includes a control circuit that receives a signal from a remote control transmitter, and a discharge lamp lighting device that lights a discharge lamp and a safety bulb based on the signal from the control circuit.
JP 2006-12750 A

ところで、このような蛍光灯照明装置は、放電灯点灯装置によって保安球を点灯させるが、図３に示すように、半導体リレー１を使用して保安球２を点灯させるものがある。   By the way, such a fluorescent lamp illuminating device lights a safety ball by a discharge lamp lighting device. As shown in FIG. 3, there is one that lights a safety ball 2 using a semiconductor relay 1.

この半導体リレー１は、ダイオード１Ａとトライアック１Ｂを備えており、ダイオード１Ａに電流が流れると、トライアック１Ｂが導通してＡＣ電源により保安球２が点灯するようになっている。制御部ＩＣ１は、図示しないリモートコントロール装置からの信号に基づいてトランジスタＴＲ１をオンさせてダイオード１Ａに電流を流したり、図示しないインバータを動作させて蛍光灯（図示せず）を点灯させたりするものである。   The semiconductor relay 1 includes a diode 1A and a triac 1B. When a current flows through the diode 1A, the triac 1B is turned on, and the protective ball 2 is lit by an AC power source. The control unit IC1 turns on the transistor TR1 based on a signal from a remote control device (not shown) to cause a current to flow through the diode 1A, or operates an inverter (not shown) to light a fluorescent lamp (not shown). It is.

しかしながら、このような蛍光灯照明装置は、半導体リレー１を設けているため高価なものになってしまう問題があった。   However, such a fluorescent lamp illumination device has a problem that it becomes expensive because the semiconductor relay 1 is provided.

また、保安球をＤＣ電源で点灯させる保安球点灯装置があるが、この保安球点灯装置は半導体リレー１の代わりにスイッチング素子を用いるため、安価なものとなるが、保安球の寿命が短くなるという問題があった。   In addition, there is a safety ball lighting device that lights a safety ball with a DC power source. Since this safety ball lighting device uses a switching element instead of the semiconductor relay 1, the safety ball lighting device is inexpensive, but the life of the safety ball is shortened. There was a problem.

この発明の目的は、保安球をＤＣ電圧で点灯させて、その保安球の寿命をＡＣ電源で点灯した場合と同レベルにすることができ、しかも安価な保安球点灯装置を提供することにある。   An object of the present invention is to provide an inexpensive safety ball lighting device that can light a safety ball with a DC voltage and have the same life as that when the safety ball is lighted with an AC power source. .

請求項１の発明は、保安球を点灯する保安球点灯装置であって、
交流電圧を整流する整流回路と、この整流回路から出力される整流電圧を断続して前記保安球に印加させるスイッチング素子と、このスイッチング素子のオン・オフを制御する制御装置とを備えている。 The invention of claim 1 is a safety ball lighting device for lighting a safety ball,
A rectifier circuit that rectifies an alternating voltage, a switching element that intermittently applies a rectified voltage output from the rectifier circuit to the protective ball, and a control device that controls on / off of the switching element are provided.

この発明によれば、保安球をＤＣ電圧で点灯させて、その保安球の寿命をＡＣ電源で点灯した場合と同レベルにすることができ、しかも安価な保安球点灯装置を提供することができる。   According to the present invention, a safety ball can be lit at a DC voltage, and the life of the safety ball can be set to the same level as when the safety ball is lit by an AC power source, and an inexpensive safety ball lighting device can be provided. .

以下、この発明に係る保安球点灯装置の実施の形態である実施例を図面に基づいて説明する。   Hereinafter, an embodiment which is an embodiment of a safety ball lighting device according to the present invention will be described with reference to the drawings.

図１に示す保安球点灯装置１０は、交流電源Ｅの交流電圧を整流する整流回路１１と、この整流回路１１から出力される整流電圧を断続しこの断続した電圧を保安球Ｌ１に印加させるスイッチング素子ＴＲ１と、このスイッチング素子ＴＲ１のオン・オフを制御する制御装置２０等とを備えている。   The safety ball lighting device 10 shown in FIG. 1 has a rectifier circuit 11 that rectifies the AC voltage of the AC power source E, and a switching that intermittently applies the rectified voltage output from the rectifier circuit 11 and applies the intermittent voltage to the safety ball L1. An element TR1 and a control device 20 for controlling on / off of the switching element TR1 are provided.

整流回路１１は４つのダイオードＤ１〜Ｄ４から構成されており、整流回路１１の出力端子１１ａには保安球Ｌ１の一方の端子が接続されている。   The rectifier circuit 11 is composed of four diodes D1 to D4, and one terminal of the safety ball L1 is connected to the output terminal 11a of the rectifier circuit 11.

この保安球Ｌ１の他方の端子は抵抗Ｒ１を介してスイッチング素子ＴＲ１のアノードに接続され、スイッチング素子ＴＲ１のカソードは接地されている。抵抗Ｒ１は、保安球Ｌ１のコールドスタート時の過電流等からスイッチング素子ＴＲ１を保護するための抵抗である。   The other terminal of the safety ball L1 is connected to the anode of the switching element TR1 via the resistor R1, and the cathode of the switching element TR1 is grounded. The resistor R1 is a resistor for protecting the switching element TR1 from an overcurrent at the time of cold start of the safety ball L1.

スイッチング素子ＴＲ１のベースは抵抗Ｒ２を介して制御装置２０の出力端子２０ａに接続されており、スイッチング素子ＴＲ１は、その出力端子２０ａから出力される制御パルスＰ（図２参照）によってオン・オフ動作するようになっている。   The base of the switching element TR1 is connected to the output terminal 20a of the control device 20 via the resistor R2, and the switching element TR1 is turned on / off by a control pulse P (see FIG. 2) output from the output terminal 20a. It is supposed to be.

制御装置２０は、集積回路から構成されており、制御パルスＰを所定周期毎に出力するようになっており、制御パルスＰのパルス幅や周期は調整できるようになっている。２１は制御装置２０を駆動させる直流電源である。
［動 作］
次に、上記のように構成される保安球点灯装置１０の動作を図２に示すタイムチャートに基づいて説明する。 The control device 20 is composed of an integrated circuit, and outputs a control pulse P at every predetermined cycle, so that the pulse width and cycle of the control pulse P can be adjusted. Reference numeral 21 denotes a DC power source for driving the control device 20.
[Operation]
Next, the operation of the safety ball lighting device 10 configured as described above will be described based on the time chart shown in FIG.

保安球点灯モードに切り換えられると（時点ｔ１）、制御装置２０の出力端子２０ａから図２の（Ｃ）に示すように制御パルスＰが出力されていく。この制御パルスＰはスイッチング素子ＴＲ１のベースに印加し、スイッチング素子ＴＲ１がオンする。制御パルスＰの電圧はＶＯである。   When switched to the safety ball lighting mode (time t1), the control pulse P is output from the output terminal 20a of the control device 20 as shown in FIG. This control pulse P is applied to the base of the switching element TR1, and the switching element TR1 is turned on. The voltage of the control pulse P is VO.

他方、整流回路１１は、交流電源Ｅの交流電圧を整流して出力端子１１ａから整流電圧を出力しているので、スイッチング素子ＴＲ１がオンしている期間だけ、保安球Ｌ１に整流電圧が印加して整流電流が流れ、保安球Ｌ１が点灯する。そして、制御パルスＰが出力されていない期間、スイッチング素子ＴＲ１がオフして保安球Ｌ１は消灯する。   On the other hand, since the rectifier circuit 11 rectifies the AC voltage of the AC power source E and outputs the rectified voltage from the output terminal 11a, the rectified voltage is applied to the safety ball L1 only during the period when the switching element TR1 is on. As a result, a rectified current flows and the safety ball L1 lights up. Then, during a period when the control pulse P is not output, the switching element TR1 is turned off and the safety ball L1 is turned off.

すなわち、図２の（Ｂ）の斜線で示す断続した整流電圧ＶＬ１が保安球Ｌ１に印加され、保安球Ｌ１は点滅することになる。この点滅が高速で行われるため、視覚的には連続点灯として認識される。なお、ちらつきがある場合には制御パルスＰの周期を短くすればよい。   That is, the intermittent rectified voltage VL1 indicated by the diagonal lines in FIG. 2B is applied to the safety ball L1, and the safety ball L1 blinks. Since this blinking is performed at high speed, it is visually recognized as continuous lighting. If there is flicker, the cycle of the control pulse P may be shortened.

このように、断続した整流電圧ＶＬ１を保安球Ｌ１に印加させるものであるから、保安球Ｌ１はＤＣ電源で点灯される状態となり、しかもこの保安球Ｌ１の印加電圧は抑制され、保安球Ｌ１の寿命を延ばすことができる。例えば、断続した整流電圧ＶＬ１をＡＣ１００Ｖ電源の７５％以下にすれば、保安球Ｌ１を交流で点灯させる場合と同等な寿命を得ることができ、さらに整流電圧ＶＬ１を上記より下げれば保安球Ｌ１の寿命はさらに延びることになる。   Thus, since the intermittent rectified voltage VL1 is applied to the safety sphere L1, the safety sphere L1 is turned on by a DC power source, and the applied voltage of the safety sphere L1 is suppressed, and the safety sphere L1 Life can be extended. For example, if the intermittent rectified voltage VL1 is reduced to 75% or less of the AC 100V power source, the life equivalent to the case where the safety bulb L1 is lit with an alternating current can be obtained, and if the rectified voltage VL1 is further lowered from the above, Lifespan will be further extended.

また、スイッチング素子ＴＲ１と制御装置２０とを設けただけであるから、その構成は至って簡単であり、安価な保安球点灯装置１０を提供することができる。   Further, since only the switching element TR1 and the control device 20 are provided, the configuration thereof is extremely simple, and the inexpensive safety ball lighting device 10 can be provided.
