Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electric elevating lighting device in which a lamp body is raised and lowered by a motor.

Conventional electric lifting type lighting equipment used in places with high ceilings that make lamp replacement and other maintenance work difficult, as shown in Fig. 1, uses a motor 5 and a wire winding that is rotationally driven by the motor 5. A lift drive unit 1 consisting of a take-up drum 6 and the like is attached to the ceiling 2 of a building, and a light body 4 equipped with a lamp 7 is suspended by a wire 3 wound around the take-up drum 6, and the light is turned on by the rotation of the motor 5. It is configured to move the body 4 up and down. In addition to the illustrated motor 5 and wire winding drum 6, the lifting/lowering drive unit 1 is equipped with a detection device (not shown) for automatically stopping the lamp at a predetermined position when the lamp is raised or lowered. Since the machine is assembled with precision parts, regular inspection along with the motor and winding drum is necessary to ensure safety and ensure long-term use. However, with the conventional device in which the lifting drive unit 1 is attached to the ceiling surface, it is necessary to construct a large-scale scaffold for inspection and work at a high place. However, there are problems such as increased costs and many risks.

The present invention aims to solve such problems, and the lamp body is provided with an elevating drive unit consisting of a motor, a wire winding drum, etc., and the wire wound around the wire winding drum is connected between the ceiling and the ceiling. In addition to suspending the lamp body in such a way that it can be raised and lowered, a cord storage section is provided on the back of the lamp body, so that when the power cord that supplies power to the lamp and motor becomes loose due to the lifting of the lamp body, this slack can be removed. The power cord is stored in the cord storage part to prevent the power cord from hanging downward from the lamp body.

Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 2 shows a side view of an embodiment of the electric lifting type illumination device of the present invention, and 4 is a lamp body equipped with a lamp 7, and a motor 5 is attached to the back of the lamp body 4, and the motor 5 rotates and is driven by the motor. In addition to the wire winding drum 6, there is also a rising side automatic stop detection device 10 for automatically stopping the lamp body 4 at a predetermined raised position, and a cord storage section 1.
1 is provided, and a lowering side automatic stop detection device 12 is provided on the lower surface of the lamp 4 to automatically stop the lamp at a predetermined lowering position. The wire 3 for suspending the lamp body 4 is wound around a wire winding drum 6, and its upper end is fixed to the ceiling surface 2. Also lamp 7
and a power cord 9 that supplies power to the motor 5,
Its lower end is stored in a cord storage part 11 and taken into the lamp body, and its upper end is connected to a power source via a connection box 13 provided on the ceiling surface 2.

Now, when a switch (not shown) outside the device is operated to close the circuit of the lamp 7, the lamp lights up. When another switch is operated to energize the motor 5, the motor and the winding drum 6 are rotated, and the lamp body 4 can be raised or lowered. When inspecting or repairing the elevating drive unit 1 such as the motor and winding drum, the lamp body 4 is lowered to the floor or near the floor, and inspection, repair, lamp replacement, etc. are performed at that position. Also, when the lamp body 4 rises, the power cord 9
However, the loosened power cord is naturally stored in the cord storage part 11 on the back of the lamp and does not hang down below the lamp.

In the above-described embodiment, the upper end of the wire 3 is fixed to the ceiling surface 2, but even if a pulley is provided on the ceiling surface and the wire 3 is passed through this pulley and its tip is fixed to the lamp body 4, the same effect can be achieved. The invention can be put into practice.

As mentioned above, the present invention allows inspection and maintenance of the lifting drive unit that lifts and lowers the lamp body from the floor.
There is no need to set up high scaffolding for inspection and maintenance, so the cost is low and the work is safe. In addition, the lower end of the power cord strung between the lamp and the ceiling is placed in the cord storage area, so when the lamp rises, the loose power cord is automatically stored in the cord storage area. As a result, the cord does not hang down below the lamp body, and therefore the lighting effect is not hindered by the cord hanging down, or the cord does not become an eyesore and spoil the aesthetics. It will be done.
