PL lamps have a long service life because they are softer in light rays and generate less heat than known light bulbs and fluorescent lamps, and are therefore welcomed. However, PL lamps, at the present time, are not as convenient as light bulbs or some fluorescent lamps of any type.

That is, it can be applied to a direct current or an alternating current power source. For example, if a transformer and a rectifier are provided in a lighthouse and a storage battery is attached, the specification can be used for both AC / DC.

Therefore, an emergency lighting lamp of a general building or an emergency lighting lamp for indicating an emergency exit is generally composed of a light bulb, and the storage battery in the emergency lighting lamp is normally supplied with alternating current and charged. The direct current of the storage battery is automatically used to make the light bulb of the emergency lighting light.

Embodiment An embodiment of the present invention will be described below in detail with reference to the drawings.

The embodiment shown in FIG. 2 to FIG. 4 is a lighting device for lighting a PL lamp (Philips Lamp) by using DC power, one PL lamp 30, one DC power supply device, that is, a rechargeable storage battery BA, An electric circuit device of one electric circuit board 20, the electric circuit device includes one self-excited DC-to-AC transformer T2 and one control circuit. The electric power of the electric circuit device is supplied by a storage battery BA. One conductive ring clamp 21 (see FIG. 5) clamps on the lamp tube of the PL lamp 30 and the ring clamp 21 is connected to the earth pole of the electric circuit device. In the control circuit in the electric circuit device, the first relay R1 controls the opening and closing of the passage from the storage battery BA to the PL lamp 30, and the second relay R2 includes the self-excited DC-to-AC transformer T2 to PL. It is used to control the opening and closing of the passage of the lamp 30.

The two relays R1 and R2 operate immediately when the storage battery BA discharges, and can output the current of the storage battery BA to the PL lamp 30.

The above-described devices exist independently, and can be applied to wall, ceiling, and desk-top type PL lamps 30, and can be a flashlight using the PL lamps 30 as a light source.

Next, under one normal condition, there is a stand for the PL lamp 30 using an AC power source, and a more detailed example of applying the present invention will be described. The stand continues even when the AC power source fails. Can be used.

FIG. 1 shows the structure of the above stand, which includes one light base 10, which is a box-shaped body having one AC power socket 11 and one power switch 12, An AC power supply can be connected with the racket 11, some switches are used to select the PL lamp main stand 42 or the sub stand 30, and some switches are used to light the lamps (described in detail later). . Separately, one storage battery BA, a rectifying transformer T1 and one electric circuit board 20 are mounted in the light base 10, and the electric circuit board 20 has the special electric circuit device as shown in FIG. 2 or FIG.

The light pedestal 10 is provided with a translucent lamp cover 14 in a part thereof, and it is desirable to provide it at one corner of the light pedestal 10. In this way, the PL lamp 30 built in the lamp cover 14 emits light. When this is done, it is possible to emit light above and to the side of the light base 10 at the same time.

The light base 10 has one fitting hole 15 and is used for fitting and fitting the light pole 40. A conductive piece 16 is provided in the fitting hole 15, while a conductive plate 41 is provided at the bottom end of the light pole 40. The conductive plate 41 is connected to the PL lamp 42 of the light column 40 by the electric current in the light column 40.

Once the light pole 40 is inserted into the fitting hole 15 of the light pedestal 10, the direct current expanded power supply of the light pedestal 10 can be used for the PL light 42 (described in detail later).

The electric circuit device is an electric circuit which mainly activates the PL lamp 30 with one AC power source, and this electric circuit is the same as a general one, and with one DC electric power, for example, 6V DC, the PL lamp 30 is used. It includes a special circuit for activating the power supply, which mainly includes a self-excited DC-to-AC transformer and one battery charging circuit, and one control circuit.

2 to 5 show a design of a circuit for starting the PL lamp 30 with direct current, a control circuit device for the circuit, a conductive ring clamp, and the like.

The electrical circuit includes one transformer T1, resistances R101 and R102, one diode D1, a first relay R1, a second relay R2, a capacitor C2, one self-exciting transformer T2 and four. 1 switch is the main lamp switch SW2, the second is the sub lamp switch SW1, the third is the momentary closing button switch SW3, and if two PL lamps 30 are installed in the equipment at the same time, One switch SW4 must be added to.

Separately, FIG. 5 shows a design of one conductive ring clamp 21 according to the present invention, which is used to clamp the tube body of the PL lamp 42 or the PL lamp 30. The ring clamp 21 and the earth pole in the electric circuit device are connected to each other, and with this design, the electronic shock in the PL lamp 30 tube is kept stable and can serve the purpose of instantaneous lighting.

It is not necessary for the momentary closing button switch SW3 row, and by using it, the PL lamp 30 is lit and self-restoring, the passage of the capacitor C2 is cut off, and the current of the storage battery BA is not continuously lost. As a result, the storage battery BA is used for a longer period of time so that the lighting effect, that is, the light emission under the blackout condition is achieved.

The operation state of the above electric circuit will be described by being divided into two situations. (1) When AC power is input: When the AC power passes through the transformer T1 and the charging current is rectified by the diode D1, it enters the storage battery BA. At this time, the circuit that switches between direct current and alternating current, which the transformer T2 bears, does not operate. This is because the transformer is in the non-conductive state under the control of the relay R1.

Under charging conditions, the resistances R101 and R102 control the charging current. Therefore, once the amount of charge of the storage battery BA is saturated, the charging current is automatically reduced gradually to prevent the life of the storage battery from being shortened due to overheating of the storage battery due to overcharging.

When using the AC power supply, by turning on the switch SW2, the power of the PL lamp (usually about 13 W) 42 as the main lamp can be supplied. (2) When the AC power supply fails: At this time, only the storage battery, which is full of electricity in normal times, is immediately discharged and current is input to the control electric circuit to switch between DC and AC. If the switch SW1 is switched to ON at this time, the contacts of the relays R1 and R2 are also automatically tripped by discharging the storage battery and connected to the position of the NC (Nomal clase) contact, and the current passes through the switch SW1 and the relay R1. , Return to one end of the storage battery BA and switch between direct current and alternating current.

At this time, the AC voltage is maintained at about 500 VPP and a frequency of 20 kHz, and this voltage output returns to the condenser C2 via the NC contact of the other relay R2, the switch SW4, and the PL lamp 42 as the main lamp. Compose one passage.

When the light pole 40 is removed from the light pedestal 10 and is shown in FIG. 2, the switch SW4 is switched to another position, an electric current is supplied, and the PL light 30 as a sub lamp of the light pedestal 10 is passed through the passage. The PL lamp 30 as the sub lamp is configured.

Therefore, regardless of whether or not there is a power outage, one of the PL lamp 42 as the main lamp or the PL lamp 30 as the sub lamp is lit, which is the PL lamp 30 for general use. There is no special feature.

Therefore, the present invention includes a product, that is, a finished product in addition to each element shown in the above-mentioned embodiment, and it is not desirable to provide two lamps at the same time as a sub lamp or a main lamp or a main lamp and a sub lamp.

The action of the switch SW3 in the electric circuit is used once when the storage battery BA is at a low voltage (about 5 V) and for starting the PL lamp 42 as the main lamp or the PL lamp 30 as the sub lamp.

The above-mentioned structure and electric circuit device are all related to the general PL lamp 30, and therefore, the purpose of the present invention can be achieved, and the purpose thereof is not the general PL lamp 30 lamp. Of.

[Effect of the device]

 Since the present invention has the above configuration, the power supply of the electric circuit device is supplied by the DC power supply such as a storage battery during the AC power failure, and the current is supplied to the fluorescent tube by the first and second relays when the DC power supply is supplied. It can be output and the PL lamp can be used with both AC / DC current. As a result, even when the PL lamp is used as an emergency lighting lamp, it is not necessary to provide a separate lighting fixture, and thus cost increase can be suppressed.

Further, when the structure has a light pedestal in which a storage battery and a charging device that is connected to the storage battery and has a function of switching from alternating current to direct current or from direct current to alternating current are provided, when the storage battery discharges, the current of the storage battery It is possible to output to the fluorescent tube and prevent the external beauty from being spoiled due to external attachment such as a storage battery.
