Abstract

PROBLEM TO BE SOLVED: To provide a lighting system for a high ceiling, simply open/close a frame body to a luminaire main body, and easily replacing a light source. SOLUTION: A frame body 12, for supporting a fore surface light transmitting plate 13, is supported opening/closing freely to a boxlike luminaire main body 11, and a light source is interlockedly moved together with opening/closing the frame body 12. A pushbutton 20 having a large area is arranged in nearby the center of the tip part of the frame body, while a hooking piece 25 is arranged in a place corresponding to the pushbutton of the luminaire main body. The key-like body 24 of the pushbutton is detached from the hooking piece 25 by pushing part of the lower surface of the large area pushbutton, and the key-like body 24 is hooked to the hooking piece 25 by pushing up part of the fore end lower surface of the frame body other than the pushbutton.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a lighting device for a high ceiling.

[0002]

2. Description of the Related Art Conventionally, for example, as shown in FIG. 4, a lighting device fixed to a ceiling of a gas station is provided with a socket 2 inside a lighting fixture main body 1, and the socket 2 has, for example, 400 watts. Metal halide lamp 3
Is configured. In addition, the lighting device body 1 and the frame 4
Lock mechanism 5 that can be opened and closed with one touch at the lower part
Is arranged. When the frame 4 is opened, a part of the wire 6 constituting the lock mechanism is pulled,
The lock is configured to be released. In order to pull a part of the wire 6, a hook-like portion provided at the tip of a long rod is hooked on a part of the wire, and the lock is released by pulling downward.

[0003]

By the way, for example, the height of the ceiling surface of a gas station is generally set to about 5 m, so that a hook-like portion at the tip of a long rod-like body is attached to a part of the wire. To engage, the worker faces the high ceiling surface,
In addition, since the hook-like portion at the tip of the long rod-like body is engaged with a part of the wire, there is a disadvantage that the operation is considerably complicated.

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and a frame formed so as to be freely openable and closable with respect to a lighting fixture main body can be easily opened and closed, and a light source can be easily replaced. It is an object of the present invention to provide a lighting device for a high ceiling, which can perform lighting.

[0005]

Means for Solving the Problems The present invention has the following arrangement to solve the above problems. For the box-shaped lighting fixture main body, the frame supporting the front light-transmitting plate is supported to be openable and closable. The present invention relates to a lighting device for a high ceiling which moves in a detachable direction. A push button having a wide area is arranged near the center of the front end of the opening / closing frame, and a hooking piece is arranged at a position corresponding to the push button of the lighting fixture body. Then, by pressing a part of the lower surface of the wide area push button, the hook-shaped piece of the push button is released from the engaging piece, and the hook-shaped piece is pushed up by pressing a part of the lower surface of the front end of the open / close frame other than the push button. It is configured to engage with the engaging piece.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to FIGS. In the figure, reference numeral 11 denotes a lighting fixture main body, which is formed in a box shape. Reference numeral 12 denotes a frame which is configured to be openable and closable with respect to the lighting fixture main body 11, and has a light transmitting plate 13 on the front surface. 14 is the lighting fixture body 11
This is a hinge portion for configuring the frame body 12 to be openable and closable. Reference numeral 15 denotes a socket supported by the frame,
It is configured to be movable in a direction in which the light source can be attached and detached from below the device in conjunction with opening and closing of the frame. 16 is socket 15
For example, a metal halide lamp of 400 watts is mounted.

Reference numeral 20 denotes a push button having a large area which is arranged near the center of the front end of the frame, and is constituted by, for example, a flat plate. Reference numeral 21 denotes a mounting screw for supporting the push button 20, which supports the vicinity of both ends. Reference numeral 22 denotes a lock mechanism disposed at a position corresponding to the push button 20, reference numeral 23 denotes a pressing body of the locking mechanism, and reference numeral 24 denotes a hook-like body that projects when the pressing body 23 is pressed. Reference numeral 25 denotes an engaging piece arranged at a position corresponding to the lock mechanism of the lighting fixture body 11.

Next, the opening and closing of the open / close frame in the above-described high ceiling lighting device will be described. (1) By pressing a part of the lower surface of the push button 20 having a large area, the pressing body 23 is pressed and the hook-like body 24 is engaged with the engaging piece 25.
The frame 12 is opened, and the lamp is turned down with the frame 12 opened. At this stage, the lamp can be easily replaced by the lamp replacement jig. (2) The hook-like body 24 is hooked on the hooking piece 25 by pressing and pushing up a part of the lower surface of the front end of the frame body 12 other than the push button 20, and the frame body 12 is easily closed with respect to the lighting apparatus main body 11. Can be.

[0009]

According to the present invention described above, in a lighting device supported on a high ceiling, an opening / closing frame configured to be freely openable / closable with respect to a lighting fixture body can be easily opened / closed, and a light source can be easily replaced. There are special effects that can be performed.
