Embodiment Construction

[0016] The inductive ballast for high-intensity gas discharge lamps of the present invention will be further described in detail below in conjunction with specific embodiments and accompanying drawings.

[0017] Such as figure 1 As shown, an inductive ballast for high-intensity gas discharge lamps in one embodiment includes a bottom plate 10, an iron core 20 fixed on the bottom plate 10, a skeleton 30 and a skeleton 40, and a coil wound on the iron core 20 through the skeleton 30, 40 (picture not viewed).

[0018] Such as figure 2 As shown, in this embodiment, the iron core 20 adopts an E-shaped iron core 22 and an I-shaped iron core 24 formed by laminating a plurality of E-shaped and I-shaped silicon steel sheets. The cross-section of the iron core 20 is roughly square, and the ratio of its height H to width L is about 5:6. This ratio minimizes the copper resistance loss of the coil and the iron loss of the iron core, and greatly reduces the heat generation of the ballast ...

Abstract

The invention relates to a high-strength gas discharge lamp inductive ballast which comprises an iron core, a skeleton and a coil, wherein the skeleton is arranged on the iron core; and the coil is wound on the skeleton. The ratio of the height to the width of the iron core is 5:6 or so. The magnetic gap of the iron core is 0.95mm or so. By reasonably setting a ballast iron core parameter and reducing the copper resistance loss of the coil and the iron loss of the iron core to the greatest extent, the heat radiation of a ballast body is greatly reduced, the magnetic flux saturation of the iron core is effectively reduced, and the solid foundation is laid for the high-strength gas discharge lamp inductive ballast disclosed by the invention to reach the national energy-saving energy efficiency standard.

Description

technical field [0001] The present invention relates to a ballast, in particular to an inductive ballast for a high-intensity gas discharge lamp (HID). Background technique [0002] In the green lighting project, the ballast is an extremely important light source electrical accessory. Compared with magnetic ballasts for high-intensity gas discharge lamps, magnetic ballasts have the advantages of resistance to instantaneous strong electric shock, small surge current, strong overload capacity, good peak-to-peak ratio, good stability, safety and reliability, and long life. Therefore, magnetic ballasts are still widely used in today's lighting industry, especially in large-area lighting projects. According to the principle, technical basis, historical development and usage statistics of these two types of ballasts, the application of inductive ballasts for high-intensity gas discharge lamps on low-power gas discharge light sources has obvious energy-saving effects and a high de...
