In the hanging type lighting fixture such as a fluorescent lamp, which is powered by the hook ceiling rosette, it is turned off immediately when the power supply is cut off by turning off the wall switch or the device switch. It is extremely inconvenient when it is desired to continue the illumination for a while, which is about tens of seconds or minutes after the turning off operation of.

The inconvenience can be solved by shutting off the power supply to the lighting equipment after a predetermined period of time by the timer operation by turning off the wall switch or the equipment switch.

However, for that purpose, it is necessary to carry out a large-scale remodeling work that requires a qualification such as a wall switch to be a timer operation type switch, or to replace the lighting equipment with an expensive one having a timer operation type equipment switch. It has to be done, and it is not something that anyone can do easily and inexpensively.

The problem to be solved by the present invention is that anyone can easily carry out a large-scale renovation work requiring qualification or replacing a lighting fixture with an expensive one equipped with a timer-operated instrument switch. Another object of the present invention is to provide an adapter-type illuminator in which a timer-off function is added to an existing hanging-type luminaire such as a fluorescent lamp only by attaching an adapter.

[0010]

The adapter type illuminator of the present invention is mounted on a case body which is detachably mounted between a ceiling ceiling ceiling body and a ceiling ceiling hook ceiling cap. ,

When B is fitted and the case body 6 is attached between the hook sealing body 2 and the hook sealing cap 18, and the wall switch 5 is turned on by the lighting operation, the AC power supply of the distribution line 4 causes the blade receiving portions 3A, 3B, hooks. Blades 7A, 7B, blade receiving portion 8A,
It is applied to the hooking blades 19A and 19B via 8B to supply power to the lighting fixture 17, and the lighting fixture 17 is turned on.

Next, the power supply circuit 11 and the power supply control circuit 16 in the case body 6 are constructed as shown in FIG.

The distribution line 4 is turned on while the lighting device 17 is on.
AC power is applied to the transformer 10, and this transformer 1
The secondary winding output of 0 is the diodes D1 and D of the power supply circuit 11.
2, the secondary battery 12 is charged by the rectified output of the power supply circuit 11 via the resistor R1.

Further, while the lighting fixture 17 is lit, a current based on the power supply flows through the primary winding of the transformer 14,
The secondary winding output of No. 4 is rectified by the diode D3, the capacitor C1, and the resistor R2 of the detection circuit 15 to form a DC energization detection signal. With this signal, the energization current detection circuit 1
The input transistor Q1 of No. 5 is kept on, and when the transistor Q1 is off, the base current supplied to the base of the charge control transistor Q2 via the resistors R3 and R4 flows to the transistor Q1. Turns off.

During charging of the capacitor C2, the resistance R
6, the discharge loop of the diode D5 and the transistor Q1 is closed, and the transistor Q3 for power supply control whose base is connected to the capacitor C2 via the resistor R6 is held off.

The diode D6 connected to the emitter of the transistor Q3 is for ensuring that the transistor Q3 is off.

Next, when the wall switch 5 is turned off by the turning-off operation, the AC power is not applied to the blade receiving portions 3A and 3B, and the lighting fixture 17 is turned off by turning off the power supply.

At this time, due to the interruption of the current in the primary winding of the transformer 14, the energization detection signal of the detection circuit 15 turns off and the transistor Q1 turns off, and at the same time the transistor Q2 turns off.

Further, when the transistor Q1 is turned off, the current of the charge charged in the capacitor C2 is supplied to the base of the transistor Q3 via the resistor R6, and this transistor Q3 is supplied.

The light of the light bulb 13 is transmitted through the transparent plastic on the peripheral surface. The auxiliary lighting is performed by being radiated to the outside of the case body 6.

It should be noted that after the lapse of the predetermined period, the transistor Q3 is turned off, the light bulb 13 is turned off, and thereafter, the light is completely turned off.

Then, a large-scale remodeling work requiring qualification is performed only by attaching an inexpensive adapter that can be easily installed by anyone who attaches the case body 6 between the hook sealing body 2 and the hook sealing cap 18 of the existing hook ceiling. It is possible to add the function of continuing the illumination for a while after the turning-off operation to the existing hanging type lighting fixture such as a fluorescent lamp, without replacing the lighting fixture or the lighting fixture with an expensive one provided with a timer-operated fixture switch.

It should be noted that the light bulb 13 is turned on even when a power failure occurs in the AC power supply while the lighting fixture 17 is being turned on, and it also functions as an emergency lighting lamp for a short period of time.

By the way, in the above-mentioned embodiment, the hanging type lighting apparatus is applied to the case where the lighting is turned on and off by the wall switch. However, the hanging type lighting apparatus is turned on and off by supplying the current of the primary winding of the transformer 14, Since it is detected from the interruption, it goes without saying that it can be applied without any inconvenience even when the lighting switch of the hanging type lighting equipment is turned on and off.

In the above embodiment, the stored energy of the secondary battery 12 is supplied to the light bulb 13, but a capacitor may be provided instead of the secondary battery 12 and the stored energy of this capacitor may be supplied to the light bulb 13.

Further, the light quantity of the light bulb 13, the lighting period and 2
