Description

[Detailed description of the invention] Industrial applications The present invention relates to a discharge lamp apparatus.

Structure of Conventional Example and Its Problems In conventional discharge lamp apparatuses, starting parts such as a glow lamp for starting the discharge lamp are often protruded from the apparatus so that they can be easily replaced. However, it is necessary to make holes for the protrusion, and there is a risk that it may become an obstacle and be damaged during packaging work. By the way, in recent years, U-shaped or double U-shaped discharge lamps have become popular, but since these discharge lamps are small, slightly larger than conventional incandescent light bulbs, the fixtures often have to be made smaller.
Therefore, it is difficult to secure a place to install starting parts, and
If the starting part were to protrude from the appliance as in the past, it would be relatively conspicuous and the product value would be reduced. Therefore, although it is desirable that the starting parts be hidden from view, it is necessary to avoid difficulties in replacing the starting parts.

Purpose of the Invention The present invention was devised based on the above-mentioned background, and while paying attention to the installation location of the starting parts,
To provide a discharge lamp fixture in which a starting part is made invisible and the starting part can be easily replaced.

Structure of the Invention In order to achieve the above-mentioned objects, the present invention includes a discharge lamp provided at the bottom of a chassis, a starting part for starting the discharge lamp provided at the top of the chassis, and coupled to the chassis. This constitutes a discharge lamp apparatus characterized in that a cover is placed on the outer periphery of the support pipe and covers the starting parts, and in addition to the above purpose, it also prevents forgetting to attach the cover when replacing the starting parts. It also seeks to prevent this.

DESCRIPTION OF EMBODIMENTS Next, embodiments of the present invention will be described with reference to the drawings.

1 is a substantially circular metal chassis, the lower part of a substantially U-shaped metal fitting 3 is passed through a square hole 2 in the center, and mounting pieces 4 formed by cutting and raising on both sides of the metal fitting 3 are screwed together. 5 is attached to the chassis 1. A socket 6 is attached to the lower surface of the metal fitting 3 with screws 7, and a discharge lamp 10 having a terminal 9 at a base 8 is attached to the socket 6, and the discharge lamp 10 is provided at the lower part of the chassis 1. Numeral 11 is a mounting screw for the glove 12, which is passed through the side edge of the chassis 1 and attached to the glove 1.
The glove 12 is attached by being tightened into an annular groove 13 formed on the upper outer periphery of the glove 2. A socket 15 into which a starting part 14 such as a glow lamp or an electronic starter is mounted is attached to the inner surface of the metal fitting 3 with screws 16, and the starting part 14 for starting the discharge lamp 10 is provided on the upper part of the chassis 1. The metal fitting 3 has a so-called burring hole 17 made by piercing.
The protruding edge 18 of this burring hole 17 is inserted into the end of the support pipe 19, and the approximately U-shaped coupling fitting 21 of the approximately U-shaped coupling fitting 21 is inserted into the cut groove 20 formed on both sides of this support pipe 19. Insert the groove edge of the notch groove 22 and tighten the coupling fitting 21 with, for example, the screw 23.
is fixed to the metal fitting 3. In this way, the cover 24 covering the starting part 14 is fitted around the outer periphery of the support pipe 19 connected to the chassis 1, and is placed on the upper part of the chassis 1. 25 is a cord, which passes from the support pipe 19 through the burring hole 17, enters the inner surface of the metal fitting 3, and connects to the socket 1.
5 and socket 6 are made.

In the present invention configured in this way, the starting component 1
4 is provided on the upper part of the chassis 1 and is hidden from view by a cover 24. Moreover, when replacing the starting part 14, the cover 24 is placed along the support pipe 19 as shown by the two-dot chain line in FIG. This can be done simply by lifting the cover 24, and once the replacement is completed, the cover 24 will return to its original position naturally when you let go of the cover 24, so you will never forget to attach the cover 24. In addition, since the protruding edge 18 of the burring hole 17 formed in the metal fitting 3 is inserted into the end of the support pipe 19, the support pipe 1
Since the relative positions of the support pipe 19 and the metal fitting 3 are determined, there is no need to bend the groove edge of the notch groove 22 of the coupling metal fitting 21 inward, and the support pipe 19 and the metal fitting 3 can be easily connected to each other by simple means. can be firmly connected.

Effects of the Invention As is clear from the above, the present invention has the following advantages:
The installation location for the starting parts is secured at the top of the chassis, and the cover hides the starting parts, improving the product value. Replacement of the starting parts can be easily done by simply sliding the cover, and once the replacement is complete, , it is possible to provide a discharge lamp apparatus in which the cover returns naturally, thereby preventing forgetting to attach the cover;
In particular, it can be usefully used in small discharge lamp equipment.
