However, since the spotlights for the stage are often installed behind the ceiling and the space behind the ceiling is small, in the conventional spotlight configured as described above, the opening / closing cover is used. It is difficult to open and close, and the opening and closing cover protrudes when replacing the lamp, which is prone to injury and the lamp replacement work is dangerous.

The present invention has been made in view of the above problems, and an object thereof is to provide a spotlight in which a lamp can be replaced easily and safely.

[0009]

In order to solve the above-mentioned problems, in the invention according to claim 1, a substantially spherical instrument for accommodating a lamp and having an irradiation port for light from the lamp is provided. In a spotlight having a main body, an opening for attaching and detaching a lamp is provided on the outer peripheral surface of the fixture main body, and an opening / closing cover that slides along the substantially spherical outer peripheral surface of the fixture main body is provided in the opening. .

Further, according to the invention of claim 2, in a spotlight having a substantially cylindrical instrument main body which houses a lamp and has an irradiation port of light from the lamp, a cylinder of the instrument main body An opening for attaching and detaching the lamp is provided on the outer peripheral surface of the shape, and an opening / closing cover that slides along the cylindrical outer peripheral surface of the instrument body is provided in this opening.

[0011]

According to the first aspect of the present invention, in a spotlight having a substantially spherical fixture main body which houses a lamp and has an irradiation port for light from the lamp, the lamp is provided on the outer peripheral surface of the fixture main body. An opening for attaching and detaching,
Since an opening / closing cover that slides along the approximately spherical outer peripheral surface of the appliance body is provided in this opening, the opening / closing cover slides along the outer peripheral surface of the appliance main body to open and close, making it easy to use even in a narrow space under the ceiling. It can be opened and closed easily and the lamp can be easily replaced.
By opening and closing, it almost disappears from the instrument body,
Lamp replacement work can be done safely.

Further, according to the invention of claim 2, in a spotlight which houses a lamp and has a substantially cylindrical instrument main body having an irradiation port of light from the lamp, a cylinder of the instrument main body An opening for attaching and detaching the lamp is provided on the outer peripheral surface of the shape, and an opening / closing cover that slides along the cylindrical outer peripheral surface of the appliance body is provided in this opening. The lamp can be easily opened and closed even in a narrow space under the ceiling, and the lamp can be easily replaced, and the lamp can be safely replaced with almost no protrusion from the main body of the fixture.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described below with reference to FIG. The spotlight shown in FIG. 1 includes an instrument main body 1 that houses a lamp, an arm 2 attached to the instrument main body 1, an opening / closing cover 3, and a guide 5 of the opening / closing cover 3.

The instrument main body 1 has a substantially spherical shape, a light irradiation port 1a is provided at a lower end thereof, bearing portions 1b are provided on both side surfaces thereof, and an opening for replacing a lamp is provided on a side surface orthogonal to the bearing portion 1b. 1c is provided.

The arm 2 is a U-shaped member formed by bending both ends of a plate, and a support shaft that rotatably engages with the bearing portion 1b of the instrument body 1 at the tip of the opposing side piece 2a. 2b is attached.

The opening / closing cover 3 is an opening 1c of the instrument body 1.
Is a plate-like member having a curved surface that is substantially the same as the outer peripheral surface of the instrument body 1.

The guides 5 are mounted on both sides of the opening 1c and are formed by a plate having a stepped curved surface for guiding both ends of the opening / closing cover 3, and the stepped portion guides both ends of the opening / closing cover 3 to cover the cover 3. Can be slid.

Therefore, the opening and closing cover 3 slides along the guide 5 to open and close, and can be easily opened and closed even in a narrow space under the ceiling, the lamp can be easily replaced, and the opening and closing cover almost projects from the main body of the fixture. And the lamp replacement work can be done safely.

And the opening / closing cover 3 and the guide 5 of the opening / closing cover 3.

The instrument main body 1 has a shape in which both ends of a cylinder are closed, and an irradiation port 1a is formed at a substantially central portion of the lower end of the cylindrical outer peripheral surface.
Is provided, an opening 1c for replacing the lamp is provided at a side portion of the outer peripheral surface thereof, and a bearing portion 1b is provided at the center of both end surfaces.

The arm 2 is a U-shaped member formed by bending both ends of a plate, and a support shaft which rotatably engages with the bearing portion 1b of the instrument body 1 at the tip of the opposing side piece 2a. 2b is attached.

The opening / closing cover 3 is the opening 1 of the instrument body 1.
It is a plate-like member that shields c and has a curved surface that is substantially the same as the cylindrical outer peripheral surface of the instrument body 1 and that has a substantially rectangular plan view.

The guides 5 are mounted on both sides of the opening 1c and are formed by a stepped curved plate that guides both ends of the opening / closing cover 3, and both ends of the opening / closing cover 3 are slidably guided by the stepped portions. ing.

Therefore, the opening / closing cover 3 slides along the guide 5 to open and close, and can be easily opened and closed even in a narrow space such as the ceiling, and the lamp can be easily replaced. It does not project and the lamp replacement work can be done safely.

[0025]

According to the invention of claim 1, the spotlight according to the present invention having the above-mentioned structure has the following features.
In a spotlight that houses a lamp and has a substantially spherical fixture body with an irradiation port for the light from the lamp, an opening for attaching and detaching the lamp is provided on the outer peripheral surface of the fixture body, and the fixture is provided in this opening. Since the opening / closing cover that slides along the substantially spherical outer peripheral surface of the main body is provided, the opening / closing cover slides and opens / closes along the outer peripheral surface of the instrument body, and can be easily opened / closed even in a narrow space under the ceiling. The lamp can be easily replaced, and the lamp almost never projects from the main body when opened and closed, so that the lamp replacement work can be performed safely.

According to the second aspect of the present invention, in a spotlight having a substantially cylindrical instrument body which houses a lamp and has an irradiation port for light from the lamp, a cylinder of the instrument body is provided. An opening for attaching and detaching the lamp is provided on the outer peripheral surface of the shape, and an opening / closing cover that slides along the cylindrical outer peripheral surface of the appliance body is provided in this opening.
