Problems solved by technology

However, depending on how the ground wire 8 is routed, uneven noise canceling performance may occur.
[0015] Furthermore, in order to avoid contact between the metal case 1 and the electronic component 3, an insulating filler 5, which is a spacer containing a non-conductive material, is interposed between the metal case 1 and the substrate 21, and the insulating filler 5 In the case of fixing the substrate 21, due to deterioration of the insulating filler 5, the adhesion to the substrate 21 deteriorates, the substrate 21 becomes unfixed, and the position of the substrate 21 to the bottom surface of the metal case 1 may not be fixed.

Embodiment approach 1

[0063] use figure 1 Embodiment 1 of the present invention will be described. Among them, for Figure 13-1 The structures common to the prior art shown in 6 are denoted by the same symbols and descriptions thereof are omitted. Additionally, the figure 1 The up, down, left, and right directions in hereinafter are used as a reference, and the direction perpendicular to the up, down, left, and right directions is taken as the front and rear directions.

[0064] The discharge lamp lighting device A of this embodiment is as follows: figure 1 As shown, it has: a hollow box-shaped metal casing 1; a substrate 2, accommodated in the metal casing 1; an electronic component 3, installed on the upper surface and the lower surface of the substrate 2, to form a discharge lamp lighting circuit; and metal components 4. It is sandwiched between the metal shell 1 and the base plate 2; the metal shell 1 is filled with an insulating filler 5.

[0065] The substrate 2 is formed in a substan...

Embodiment approach 2

[0082] use Figure 9 Embodiments of the present invention will be described.

[0083]The discharge lamp lighting device B of the present embodiment differs from the discharge lamp lighting device A of the first embodiment in that the outer dimensions of the substrate 12A are substantially equal to the inner dimensions of the metal case 1, and are only the same as the substrate 2 of the first embodiment. The shape is different. However, other configurations are the same as those of the discharge lamp lighting device of Embodiment 1, and description thereof will be omitted.

[0084] The substrate 12A is formed in a substantially rectangular plate shape having substantially the same external dimensions as the bottom surface of the metal case 1 , and has substantially rectangular notches 12 a formed on each side.

[0085] As described above, since the outer dimensions of the substrate 12A are approximately equal to the inner dimensions of the metal case 1 , by being accommodated...

Embodiment approach 3

[0090] use Figure 11 (a)-(c) The lighting fixture of this embodiment is demonstrated.

[0091] The lighting fixture of this embodiment includes the discharge lamp lighting device described in Embodiment 1, Figure 11 (a) means a downlight to which the discharge lamp lighting device A is applied, Figure 11 (b)(c) shows the spotlight to which this discharge lamp lighting device A is applied.

[0092] in addition, Figure 11 The lighting fixtures shown in (a) to (c) include: a discharge lamp lighting device A; a discharge lamp 14 receiving power from the discharge lamp lighting device A directly or via a cable 13; and a fixture main body 15 to which the discharge lamp 14 is attached. .

[0093] The lighting fixture of the present embodiment including the above-mentioned structure can perform electrical connection between the ground electrode of the substrate and the metal case and fixation of the substrate without causing enlargement, cost increase, or uneven noise cancelin...

Abstract

The invention provides a discharge lamp lighting device and a lighting fixture, capable of electrically connecting a ground electrode of a substrate and a metal shell and fixing the substrate and ensuring the insulatibity between the metal shell and a discharge part without macro-scale operation of the discharge lamp lighting device, increased cost and uneven noise elimination performance, comprising a metal shell; a substrate with one surface in parallel to the bottom of the metal shell and housed; an electronic part mounted on the substrate; an insulation filler filled into the space between the bottom of the metal shell to the top of the electronic part at the highest position in the electronic part at least mounted on one surface of the substrate; and a metal part with one end contacting with the bottom of the metal shell, wherein a bolt hole passing through another end is in screw connection with the screw for inserting into the insert hole formed on the ground electrode of the substrate and the metal shell is mechanically connected with the substrate and the ground electrode is electrically connected with the metal shell and the metal part is longer than the electronic part at the highest position in the electronic part mounted on one surface of the substrate.

Description

technical field [0001] The present invention relates to a discharge lamp lighting device and a lighting appliance. Background technique [0002] In recent years, discharge lamp lighting devices equipped with electronic components constituting a discharge lamp dot lighting circuit have become widespread. In addition, these electronic components are often covered with a metal case in order to improve heat dissipation or in accordance with the Electrical Appliance and Material Safety Law in Japan. In addition, due to the demand for miniaturization of the discharge lamp lighting device, an insulating filler is often filled in the metal case. [0003] For example, as such a discharge lamp lighting device, such as Figure 12 As shown, the following device is provided, equipped with: a hollow box-shaped metal casing 1, a substrate 21 accommodated in the metal casing 1, an electronic component 3 mounted on the substrate 21, and a metal casing 1 and the substrate 21 A spacer 41 com...
