Description

[Detailed description of the invention] [Technical field] This invention is a lamp that can be mounted on the high ceiling of a gymnasium, auditorium, theater, etc., and can be raised and lowered so that the lamp can be maintained, inspected, and replaced from the floor. It relates to lighting equipment.

[Background technology]

Conventionally, the entire lighting fixture, including the lighting lifting device, was inserted vertically upward into the mounting hole of the ceiling board. For this reason, it was not possible to use a device that was larger than the mounting hole as the lamp lifting device. This has placed restrictions on the lifting speed of the lamp and the weight of the lamp that can be hung.

[Purpose of invention]

The purpose of this invention is primarily to provide an elevating type lighting fixture that eliminates the above-mentioned restrictions and can employ a lamp elevating device that is larger than the mounting hole.

[Disclosure of invention]

The lifting type lighting fixture of this invention has a built-in lighting fixture that can be raised and lowered and is configured to be slightly smaller than the mounting hole in the ceiling plate, and a lighting equipment lifting device that is located above the fixture body and configured to be larger than the mounting hole. In between, it connects these two parts and has a neck part that is thinner than either of them, and this neck part is attached to one side of the mounting hole with the lamp lifting device in an oblique position. The lamp is configured to have a size that allows the other side of the lamp lifting device to pass through the mounting hole when one side of the lamp is in the fitted state.

That is, by fitting the lamp lifting device into the mounting hole in a swinging manner, it is possible to employ a lamp lifting device larger than the mounting hole.

An embodiment of this invention will be explained based on FIGS. 1 to 3. 1a is a perfect circular mounting hole formed in the ceiling plate 1. Reference numeral 2 denotes a fixture main body, in which a lamp 3 is built in such a manner that it can be raised and lowered. The elevating lamp 3 consists of a socket 3a, a lamp 3b screwed into the socket, and a shade 3c which is an internal reflecting mirror.
A socket 3a is suspended by a wire 4. Reference numeral 5 denotes a neck portion integrally erected from the center of the upper plate portion 2A of the instrument main body 2;
The socket 3a is housed in a space inside the socket. Reference numeral 6 denotes a lamp lifting device which is rectangular in plan view and is integrally connected to the upper part of the neck portion 5, and includes, for example, a winding drum (not shown) for the wire 4 and a drive motor (not shown) for the winding drum 6. The motor is built-in, and the motor can be rotated forward, reversed, and stopped by remote control. Since various types of lamp elevating devices are known, a detailed explanation thereof will be omitted here. Reference numeral 7 denotes a hanging bolt that penetrates the upper plate portion 2A of the appliance main body 2 and is fastened from the lower inside with a double nut 8, and the upper end of this hanging bolt 7 is fixed to a ceiling base (not shown). A flange edge 2B at the lower end of the appliance main body 2 is adapted to abut against the lower surface of the ceiling plate 1.

When inserting the lighting fixture configured as described above into the mounting hole 1a of the ceiling plate 1, place the lighting device lifting device 6 in an oblique position as shown in FIG. Then push it diagonally upward and operate it so that the neck part 5 fits into one side of the mounting hole 1a. In this state, the lamp lifting device 6
The other side part is in a position where it can pass through the other side part of the mounting hole 1a from bottom to top, and by passing it in this way, the entire lamp lifting device 6 can be moved to the top of the ceiling plate 1 as shown in FIG. Place it on the back. Next, as shown in FIG. 3C, when the center of the mounting hole 1a and the center of the fixture body 2 are aligned and the entire lighting fixture is lifted, the fixture body 2 will fit into the mounting hole 1a, and the hanging bolt 7 will be attached to the upper plate part. It fits into the hole 2A, and the collar edge 2B comes into contact with the lower surface of the ceiling board 1. And double nut 8 to hanging bolt 7
Screw on. At this time, the lamp 3 such as the socket 3a
Since the screws are not set, the screws can be easily and easily tightened even in a narrow space inside the instrument body 2. Next, the lifting device 6 is driven to wind up the wire 4.
This guide function prevents the lamp 3 from swaying and allows the lamp 3 to be set in a stable manner.

[Effect of idea]

According to the lifting type lighting fixture of this invention, it is possible to use a device that is larger than the mounting hole in the ceiling plate as the lighting equipment, thereby eliminating the conventional restrictions on the lifting speed and weight of the lighting equipment. It has the effect of being able to relax.
