A shell structure of an explosion-proof lamp and a high-pressure gas discharge lamp

Abstract

The invention relates to a housing structure for an explosion-proof lamp and a high-pressure gas discharge lamp using the housing structure. The housing structure comprises a main radiating housing used for accommodating a light source chamber, wherein the main radiating housing is provided with a plurality of separate explosion-proof cavities used for independently accommodating electronic control units. The plurality of separate explosion-proof cavities are respectively hung and fixed on the outer surface of the main radiating housing. The housing structure for explosion-proof lamp and the high-pressure gas discharge lamp, through isolation of a capacitor and a trigger from an inductance ballast and a light source, can effectively solve the problem of temperature influence to the capacitor and the trigger, and improve the service life of the capacitor and the trigger, thereby effectively improving the overall service life of the lamp, reducing the maintenance cost and greatly enhancing the using effect of users, and having a high economic benefit and a great practical application value.

Description

【Technical field】 [0001] The invention relates to a lamp, in particular to a shell structure of an explosion-proof lamp and a high-pressure gas discharge lamp. 【Background technique】 [0002] High-pressure gas discharge lamps are widely used in roads, highways, airports, docks, docks, stations, squares, street intersections, Industrial and mining enterprises, parks, garden lighting and plant cultivation, etc. For example, high-color high-pressure sodium lamps are mainly used for lighting in gymnasiums, exhibition halls, casinos, department stores and hotels. [0003] At present, high-pressure gas discharge lamps are mainly driven by inductive ballasts, which are mainly composed of inductive ballasts, capacitors, and triggers. Inductive ballasts are high-heating components, but they can withstand high temperatures; capacitors and triggers themselves generate heat It is not obvious, but it is seriously affected by temperature. Generally, if the temperature rises by 10°C, the ...

[0003] At present, high-pressure gas discharge lamps are mainly driven by inductive ballasts, which are mainly composed of inductive ballasts, capacitors, and triggers. Inductive ballasts are high-heating components, but they can withstand high temperatures; capacitors and triggers themselves generate heat It is not obvious, but it is seriously affected by temperature. Generally, if the temperature rises by 10°C, the life span will be reduced by half

[0004] The structure of a general magnetic ballast assembly is as follows figure 1 As shown, wherein, the magnetic ballast 102, the trigger 104 and the capacitor 101 are all arranged in a flameproof cavity, and the wiring is carried out through the increased safety wiring cavity 103; however, the heat emitted by the magnetic ballast and the light source causes the capacitance and The temperature of the flip-flop increases, which seriously affects the life of the capacitor and flip-flop
