Abstract

<P>PROBLEM TO BE SOLVED: To provide a ceiling embedded luminaire capable of facilitating replacement work of a light source, since a cylindrical body in an expanded skirt shape is provided in a frame covering the peripheral fringe of the opening of a luminaire body, and the frame hard to hold can be easily pulled down by using it as a frame pulling part. <P>SOLUTION: A luminaire body 10 having an opening in its lower surface is provided. A light source 40 disposed in the inside of the luminaire body 10 is provided. A frame 30 covering the peripheral fringe of the opening of the luminaire body 10 is provided. A translucent plate 50 supported by the frame 30 while covering the opening part in the lower surface of the luminaire body 10 is provided. A V-shaped spring 70 both leg parts of which expand upward in a V shape is provided. The intersection of the V-shaped spring 70 is mounted to the frame 30. A bracket 11 to elastically accept both legs of the V-shaped spring 70 is formed on the inside surface of the luminaire body 10. The bracket 11 elastically supports the frame 30 through the V-shaped spring 70. The cylindrical body 60 mounted along the frame 30 is provided. The cylindrical body 60 is formed into the expanded skirt shape the lower diameter of which expands. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  The present invention relates to a ceiling lighting apparatus. In particular, the present invention relates to the frame mounting structure.

  When a translucent plate is attached to a ceiling embedded lighting fixture, the translucent plate must be removed when replacing the light source inside the fixture. There is also known a method in which the frame that supports the light-transmitting plate is made as a separate detachable piece, and this frame that is difficult to grasp when replacing the light source is forcibly grasped and pulled down.

  For ceiling-embedded instruments with a translucent plate on the lower surface, the lower surface is blocked by the translucent plate, and when replacing the light source, the frame on which the translucent plate is supported must be pulled down and removed. The structure is not possible. In addition, since the frame is strongly pulled by a so-called V spring to the bracket of the instrument body, it is difficult to grasp a thin frame that is difficult to grasp and pull it down.

  In the present invention, it comprises a frame that covers the peripheral edge of the opening of the instrument body, a translucent plate that covers the lower surface opening of the instrument body and is supported by the frame, and a V spring that has both legs extending upward in a V shape, An intersection of the V springs is attached to the frame, and a receiving bracket that elastically receives both legs of the V spring is formed on the inner surface of the instrument body. The receiving bracket elastically receives the frame through the V spring. It is provided with a cylindrical body mounted along the month U frame, and the cylindrical body is formed in a hem-expanded shape having a lower diameter.

  According to the present invention, it is possible to easily lower the frame that is difficult to grasp by providing a hem-expanded cylindrical body on the frame that covers the green space between the closures of the instrument body, and using it as the frame lowering part, so that the light source replacement work Can be easily done.

  An embodiment of the present invention will be described with reference to FIG. A ceiling-embedded lighting fixture according to the present invention includes a lower-opening fixture main body 10, a light source (incandescent light bulb) 40 disposed inside the fixture main body 10, and a frame that covers the open U-circular green of the fixture main body 10. 30, a translucent plate 50 that covers the lower opening of the instrument body 10 and is supported by the frame 30, a V spring 70 that has both legs extending upward in a V shape, and the intersection of the V springs 70 A receiving bracket 11 that is mounted on the frame 30 and elastically receives both legs of the V spring 70 is formed on the inner surface of the instrument body 10, and the receiving bracket 11 elastically supports the frame 30 via the V spring 70. The cylindrical body 60 is mounted along the frame 30, and the cylindrical body 60 is formed in a hem-like shape with a lower diameter.

  Since the frame 30 can be pulled down with the cylindrical body 60 attached thereto, the light source 40 can be easily replaced. Further, since the tubular body 60 is formed in a flared shape, there is little or no harmful light shielding. The cylindrical body 60 is like a handle that spreads and holds both hands, thereby facilitating replacement of the light source 40. Reference numeral 20 denotes a reflector.
