Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a downlight which is attached to a lower part of furniture such as a lamp hood or a ceiling and illuminates an upper surface of furniture such as a lamp. The present invention relates to a down light having a mounting case to be mounted.

[0002]

2. Description of the Related Art A down light is, for example, as shown in FIG.
It is provided at the lower part of the lamp hood and illuminates the lamp below the lamp hood or the cooking utensils above it. In addition, it can be mounted on the ceiling to illuminate the room, or used as a study desk with a bookshelf etc. Is what is being done.

[0003] Such a downlight is housed and mounted in a lamp hood or the like which supports the downlight, and in order to make the lower surface thereof substantially the same as the lower surface of the lamp hood, for example, FIG. The structure is as shown. That is, in the conventional downlight shown in FIG. 8, the case supporting the lamp must be inserted into the inside of the bottom plate 200 through the opening 210 of the bottom plate 200 attached to the lower surface of the lamp hood or the like, and fixed to the bottom plate 200. Therefore, a spring whose tip resiliently swings downward is attached to the case. In other words, this conventional down light has a structure in which each spring is flipped up to the case side, inserted through the opening 210, and released when each spring is completely settled inside the bottom plate 200. It is supported on the inner surface side of the bottom plate 200 by the generated force.

[0004] However, when such a spring is used, its swing range must be sufficient, so that the present invention can be applied to the case where a large space exists on the inner surface side such as a ceiling. However, it cannot be applied to such things as lamp hoods which are completed as one and do not have sufficient room. Further, in a downlight using a spring as shown in FIG. 8, there is a problem that the spring force of the spring gradually weakens, and the downlight itself comes down from the bottom plate 200.

[0005] If the down light descends from the bottom plate 200, not only the appearance is very poor, but also the down light and the bottom plate 20 are not good.
Thus, a gap is formed between the zero point and zero. This gap is
If the downlight is used for a lamp hood, it becomes a passage through which oil smoke enters the downlight. Oil fumes have a very bad effect on down lamps, especially when they are xenon lamps, and are a cause of reducing the life of the lamp to 1/10 or less. On the other hand, when the gap between the downlight and the bottom plate 200 is formed on the ceiling side, it is natural that the airtightness of the room is impaired.

The inventor of the present invention has conducted various studies on how to solve the above-described problem in this type of downlight, and as a result, completed the present invention.

[0007]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems in this type of downlight, and the problem to be solved is to solve the problem with respect to the bottom plate 200 of this type of downlight. The purpose is to make mounting easy.

That is, the object of the present invention is to
The down light that illuminates the upper surface of the furniture, such as the wrench, can be easily attached to the lower part of the furniture, such as the hood, or the lower surface of the ceiling, and after installation, the supporting and fixing can be reliably maintained for a long time. An object of the present invention is to provide a downlight capable of maintaining sufficient airtightness with a simple configuration.

[0009]

In order to solve the above problems, the means adopted by the present invention will be described with reference to the reference numerals used in the embodiments described later. Bottom plate 20 attached to lower part or lower surface of ceiling

Therefore, the gap is not formed between the mounting case 10 and the lamp 30 so as to allow the flow of gas such as oil smoke.

Incidentally, with respect to the down lamp 100, if a spring 60 for pressing the lamp 30 toward the flange 21 is interposed between the lamp 30 and the mounting case 10, the lamp 30 is always moved toward the flange 21 by the spring 60. Since the lamp 30 is pressed, the lamp 30 does not vibrate or displace due to vibrations applied to the lamp hood or the like at the time of a switch operation, and the lamp 30 is securely supported on the bottom plate 200. Also,
Even if the bottom plate 200 is inclined,
Since the lamp 30 is constantly pressed toward the flange 21 by the spring 60, no gap is formed between the lamp 30 and the mounting case 10 side.
It does not create gaps that allow oil smoke or cool air to flow.

Further, a downlight 10 according to the following embodiment is described.
0, the lower surface of the lamp 30 accommodated in the mounting case 10 is received by the receiving flange 42 of the support frame 40 mounted on the lower end opening 11 of the mounting case 10, so that the operation when replacing the lamp 30 is performed. Is easy to do.

That is, in the down lamp 100 of the embodiment, when the lower surface of the lamp 30 to be replaced is slightly pushed up, the lamp 30 and the receiving flange 42 on the support frame 40 side are pressed.
The gap between the finger and the tool can be formed between them. Therefore, if a tool or the like is inserted and pryed into this gap, the support frame 40 can be easily removed from the mounting case 10 side. This is because the support frame 40 is merely engaged with the decorative plate 20 or the mounting case 10 via the support claws 41.

If the support frame 40 is detached from the mounting case 10 as described above, the lamp 30 can be easily taken out, and the replacement operation can be easily performed outside the down lamp 100. .
