Embodiment Construction

[0039] An embodiment of a discharge lamp lighting device and a lighting fixture according to the present invention will be described with reference to the drawings. First, in the first embodiment, Figure 1 to Figure 3 Indicates the discharge lamp lighting device 1, figure 1 is an exploded perspective view, figure 2 It is a vertical sectional view with the cover removed, image 3 It is a perspective view showing the assembled state. exist figure 1 Among them, the discharge lamp lighting device 1 consists of a box body 2, a cover body 3 that closes the upper surface of the box body body 2, and a cover body 3 that closes both sides of the box body body 2, and the box body body 2. A case 5 constituted by end plates 4 on both sides, a printed circuit board 6 provided in the case 5 , and an insulating filler 7 filled in the case 5 are constituted.

[0040] The box main body 2 has a substantially U-shaped cross section and is formed by extrusion molding of a metal material suc...

Abstract

The invention provides a kind of lamplighter of discharge lamp and luminaire in prolate closed box body capable of injecting insulative filling material in transverse state, being steadily stored until to hardening state and reducing filling material. The lamplighter of discharge lamp (1) of the box body (5) is composed of prolate box main part (2) with a rough cross-sectional shape in the section, open upper surface and two lateral surfaces, cover body (3) sealing the box main part (2) and end plates sealing the lateral surface of the box main part (2). It contains supporting part (2e), printing substrate (6) with lighting circuit parts (6a) supported on the supporting part (2e) and insulative filling material (7) filled in the box body (5). The filling material (7) and printing substrate (6) cover the lighting circuit parts (6a).

Description

technical field [0001] The present invention relates to a discharge lamp lighting device and a lighting fixture using the discharge lamp lighting device. Background technique [0002] In recent years, inverter-type electronic stabilizers composed of electronic components such as semiconductor elements have been used as lighting devices for lighting high-pressure discharge lamps such as high-pressure sodium lamps and metal halide lamps, and low-pressure discharge lamps such as fluorescent lamps. These lighting devices are sometimes installed outdoors, and are exposed to high humidity in environments such as rain, snow, or rainy season. Therefore, the box for accommodating the lighting circuit components is configured as an airtight type. [0003] In contrast, there is a discharge lamp stabilizer in which a bottomed metal box is filled with an insulating filler of resin for the purpose of reducing the temperature rise of the stabilizer (see Patent Document 1). During the asse...
