It is characterized by being provided with a protective frame (8) which is fixed and protects the lamp.

Further, the temporary lighting device of the present invention comprises a device body (2) fixed to a cord (6) connected to a power line, and a lamp (fluorescent lamp) attached to a lamp socket (12) of the device body. A lamp 10), a protective frame (8) fixed to the apparatus body to protect the lamp, a heat ray sensor (16) attached to the protective frame to detect the presence or absence of a person in a portion to be illuminated, When the heat ray sensor detects the presence of a person, the lamp is turned on, and when the heat ray sensor detects the absence of a person, the lamp is turned off after waiting for a certain time after the detection. Means (lighting circuit 22, timer device 24).

[0008]

[Action]

 This temporary lighting device is lightweight and portable, and can be used by hanging it from an appropriate place with a cord. The lamp is protected by a protective frame, which protects the lamp from contact and impact force during work, thus enhancing safety.

Further, in this temporary lighting device, the presence or absence of a person is detected by the heat ray sensor. The power supply switching means switches the power supply to the lamp according to the detection output from the heat ray sensor, lights the lamp when a person is present, and waits for a certain period of time after the heat ray sensor detects the absence of the person. After the elapse, the power supply is cut off. Therefore, unnecessary lighting can be prevented. In addition, this temporary lighting device is lightweight, and can be hung by a cord at an arbitrary position for lighting.

【Example】

 Hereinafter, the present invention will be described in detail with reference to the embodiments shown in the drawings.

FIG. 1 shows an embodiment of the temporary lighting device of the present invention. This temporary lighting device is installed in a temporary building, and a trapezoidal device main body 2 is installed in this temporary lighting device, and the ceiling surface of this device main body 2 is for waterproofing. The cord 6 is pulled out through the rubber seal portion 4. A plug (not shown) is connected to the cord 6, and is connected to a power line through this plug to supply power.

Further, a basket-shaped protection frame 8 is attached to the lower surface side of the apparatus main body 2, and a fluorescent lamp 10 is installed inside the protection frame 8 to protect it from external force. As the fluorescent lamp 10, a fluorescent lamp or the like which is a compact type and has a high light emission amount is used by bending a tube. The fluorescent lamp 10 is mounted on a lamp socket 12 mounted on the lower surface side of the apparatus main body 2. Has been. The protective frame 8 is composed of a plurality of vertical ribs 9 and horizontal ribs 11, and these are formed in a cage shape with an interval enough to protect the fluorescent lamp 10 without impairing the illuminance.

A sensor unit 14 for detecting the presence or absence of a person is attached to the bottom surface of the protective frame 8, and a heat ray sensor 16 is installed on the lower surface side of the sensor unit 14, and the detection unit is the fluorescent lamp 10. It is installed on the center line of the car and enables the detection of the presence or absence of people centered on the lighting position. A pipe 18 for guiding wiring is installed between the sensor unit 14 and the apparatus main body 2, and the pipe 18 has a power supply switching means side installed in the sensor unit 14 and the apparatus main body 2. It has a built-in wire that makes an electrical connection with.

Next, FIG. 2 shows a vertical cross-section of this temporary lighting device. Inside the main body 2 of the device, a power supply unit 20, a lighting circuit 22 as a power supply switching means, and a timer device 24 are provided in a frame 26. It is installed with. On the bottom side of the frame 26, a cover plate 28 for closing the bottom side of the apparatus body 2 is attached with a packing 30 interposed therebetween to prevent water droplets from entering. Further, the packing 32 is also interposed at the fixing portion of the pipe 18 to prevent water droplets from entering from the fixing portion.

Next, FIG. 3 shows an upper surface portion of the main body 2 of the temporary lighting device. A ring-shaped tightening ring 35 is fixed to the rubber seal portion 4, and the cord 6 is pulled out from the pull-out side. Water droplets are blocked.

Next, FIG. 4 shows a lower surface portion of the temporary lighting device, in which the vertical ribs 9 are gathered in the central portion to form a bottom surface portion to protect the sensor portion 14.

Next, FIG. 5 shows an example of a lighting device system of this temporary lighting device. A commercial power supply 36 is supplied to the lighting circuit 22 via a cord 6, and a fluorescent lamp 10 is connected to the lighting circuit 22. A timer device 24 is connected to the lighting circuit 22, and the heat ray sensor 16 is connected to the timer device 24. The heat ray sensor 16 detects the presence or absence of the heat ray emitted by a person, and the timer device 24 receives the detection output and generates a timer output. Then, the lighting circuit 22 receives the timer output and switches the power supply to the fluorescent lamp 10 to turn it on or off. Therefore, the lighting circuit 22 and the timer device 24 constitute power supply switching means.

The usage and operation of the above configuration will be described. As is clear from the structure, this temporary lighting device has portability. For example, as shown in FIG. 6, the cord 6 is hung on the beam 38 of a temporary building or construction member to suspend the lighting device. It can be used by lowering it. In this case, the illumination space is in the hanging direction, and the lower part is the detection area.

Therefore, when the power is supplied through the cord 6, the lighting circuit 22, the timer device 24, the sensor unit 14 and the heat ray sensor 16 are in the operating state, and when a person is present in the building, the operation shown in FIG. As shown in A, the output of the timer device 24 is, for example, a high (H) level output based on the detection signal S from the heat ray sensor 16. At this time, the lighting circuit 22 receives the output and lights the fluorescent lamp 10.

When a person exits the building and the heat ray sensor 16 detects the absence of the person, the detection signal is added to the timer device 24. As shown in FIG. 7B, the timer device 24 generates a timer signal T at a time t ₂ when a certain time T _{o has} elapsed from the time t ₁ at which the heat ray sensor 16 detects the absence of a person, that is, the timer signal T. The fluorescent lamp 10 is extinguished as the signal shifts to the low (L) level. As a result, unnecessary power consumption can be suppressed.

FIG. 8 shows another embodiment of the temporary lighting device of the present invention. This temporary lighting device is configured by excluding the pipe 18, the sensor unit 14, the heat ray sensor 16 and the timer device 24, and is made lighter than the temporary lighting device shown in FIG.
