Problems solved by technology

[0007] However, due to the excessive temperature rise in the casing of the electrical equipment, the electronic components used for a long time are damaged, which often makes the life of the electrical equipment end. end of life
In other words, in electronic components, electrolytic capacitors may degrade charging characteristics due to other reasons entirely related to thermal influence, and lose their function as capacitive components.

Embodiment Construction

[0070] Below, refer to Figure 1 to Figure 4 One embodiment of the electric equipment of the present invention will be described.

[0071] figure 1 It is a sectional view showing the first embodiment of the electric equipment of the present invention, figure 2 It is a plan view of a circuit board housed in the same electric device. Such as figure 1 As shown, the electric device 7 is constituted by a case 4 that accommodates a circuit board 30 on which electronic components are assembled.

[0072] The casing 4 is made of, for example, an aluminum plate and is rectangular. It consists of a box-shaped cover 5 with one side open and a rectangular box-shaped bottom case 6 with one side open. The cover 5 is joined to the side surfaces 6a of the bottom case 6 respectively. . In addition, no substantial ventilation holes are formed in the casing 4 .

[0073] Such as figure 2 shown. The circuit board 30 is a structure of a discharge lamp lighting device using an inverter circ...

Abstract

Provided is an electric device with long life of which, an electrolytic capacitor is restrained from explosion, even if the electrolyte capacitor is mounted inside a case. The electric device 7 comprises a circuit board 30 on which, electrolytic capacitors 34, and electronic components 32 using resin material containing halide by 1.0 mass% or less at bromine conversion, are mounted; and a case 4 covering the circuit board 30. As the content of halide contained in the resin used for the electronic components 32 is made 1.0 mass% or less, the electrolyte capacitors 34 are protected form the loss of function at early stage caused by erosion, and the electronic device 7 is prevented from having a short life.

Description

[0001] This application is a divisional application of the patent application for invention with the application number 02108513.7 filed on March 29, 2002, entitled "Electrical Equipment". technical field [0002] The present invention relates to an electric device in which a circuit board assembled with an electrolytic capacitor and electronic components using synthetic resin is accommodated in a case. Background technique [0003] Electric devices such as discharge lamp lighting devices for lighting devices are becoming lighter and smaller because electronic components are assembled on circuit boards with wiring patterns printed on the boards. In particular, the discharge lamp lighting device can achieve greater weight reduction and miniaturization than conventional electrical equipment that uses an iron core coil as a current limiting element by using an inverter using electronic components. [0004] As described in Japanese Patent Application Laid-Open No. 8-329731, the ...
