The fluorescent lamp 16 is attached to the shade 14 by inserting a plug (not shown) of the fluorescent lamp 16 into an outlet (not shown) provided in the shade cover 15. The seed cover 15 is provided with an ion emission port 17 for releasing negative ions generated by the ion generator.
Is covered with a net 18.

In the base 12, there are provided a ballast 21 for starting the lighting of the fluorescent lamp 16 and for keeping the discharge current in the fluorescent lamp 16 constant during lighting, and an ion generating circuit section 22 in the ion generator. It has been incorporated. On the upper surface of the base 12, a touch switch 23, which is an illumination switch for turning on and off the fluorescent lamp 16,
An ion generation switch 24 for operating and stopping the ion generator is provided.

On the bottom surface of the base 12, when the stand illuminator with ion generator 11 falls, the pressure from the mounting surface of the stand illuminator with ion generator 11 is released, and the whole stand illuminator with ion generator 11 is released. A fall-off switch 25 is provided for shutting off the power supply to the equipment and preventing a fire. 50 or 60 on the back of the base 12
A power cord 26, which is supplied with a commercial AC power of 100 V at Hz, is connected. The power cord 26 is also wired from the base 12 through the flexible shaft 13 to a region between the shade 14 and the shade cover 15. ing.

FIG. 2 shows the entire circuit of the stand illuminator 11 with an ion generator. A resonance capacitor 27 is connected in parallel to the fluorescent lamp 16, and the fluorescent lamp 16, the ballast 21, the resonance capacitor 27, and the touch switch 23 constitute an illuminator 28. An ion generating electrode section 33 including an electrode needle 31 and a ground plate 32 is connected to the ion generating circuit section 22, and the ion generating circuit section 22, the ion generating electrode section 33, and the ion generating switch 2 are connected.
An ion generator 34 is constituted by 4 and.

The ballast 21 is driven by the touch switch 23 to start the lighting of the fluorescent lamp 16 as described above. Since the illuminator 28 and the ion generator 34 are connected in parallel with each other, the illuminator 2 using the touch switch 23
8 and the operation of the ion generator 34 by the ion generation switch 24 can be performed independently of each other. Since the tip-off switch 25 is connected in series with the illuminator 28 and the ion generator 34, as described above, when the pressure from the mounting surface of the stand luminaire 11 with the ion generator is released, ions are generated. The power supply to the entire lighting fixture 11 with a device is shut off.

FIG. 3 shows a region between the shade 14 and the shade cover 15. A tubular electrode holder 35 is attached to the portion of the shade cover 15 on the side of the shade 14 and around the ion emission port 17, and the electrode needle 3
1 and the ground plate 32 are fixed to the electrode holder 35. The electrode needle 31 is made of stainless steel having a diameter of 1.0 mm, and the tip of the electrode needle 31 is sharpened to have a diameter of 0.03 mm or less. The electrode needle 31 and the ground plate 32 are connected to the ion generating circuit section 22 by a high voltage line 36 and a ground line 37, which pass through the flexible shaft 13, respectively.

FIG. 4 shows the ion generating circuit section 22 and the ion generating electrode section 33 connected thereto. The ion generating circuit unit 22 accumulates electric charges in the capacitor C ₁ by the circuit passing through the capacitor C ₁ , the resistor R ₁ , and the diode D ₁ in the positive half-wave period of the commercial AC power described above. Then, in the next negative half-wave period, the resistance R ₃ ,
Gate G of silicon controlled rectifier SCR, cathode K of silicon controlled rectifier SCR, diode D ₂ , transformer T
_{When a} current flows in the circuit passing through the primary coil of ₁ to trigger the silicon controlled rectifier SCR, the charge accumulated in the capacitor C ₁ is the primary coil of the transformer T ₁ , the anode A of the silicon controlled rectifier SCR, the silicon controlled rectifier. It is instantaneously discharged by the circuit passing through the cathode K of the SCR and the capacitor C ₁ .

[0015] At this time, the current to the primary coil of the transformer T ₁ is by flow instantaneously, high voltage is generated in the secondary coil of the transformer T _1. By cutting the positive waveform portion of this high voltage with the diode D ₃ , a minus pulse of about −5 kV as shown in FIG. 5 is applied to the electrode needle 31, and the sharp tip of the electrode needle 31. Generates negative ions. As shown in FIG. 5, the negative pulse is repeatedly generated at the frequency of the supplied AC power, so that negative ions are continuously supplied from the ion emission port 17 to the vicinity of the stand luminaire 11 with the ion generator. It

The Zener diode ZD ₁ and the resistor R ₄ in the ion generating circuit section 22 keep the voltage for accumulating the electric charge in the capacitor C ₁ constant, so that the electrode needle can be used even if the commercial AC power fluctuates. It is used to keep the voltage between 31 and the ground plate 32 constant. That is, the Zener diode ZD ₁ and the resistor R ₄ have a function of constantly generating a certain amount of negative ions from the ion generating electrode portion 33 even if the commercial AC power has a voltage fluctuation.
