Description

Electrical wares box for lamps

Technical field

The utility model relates to a kind of electric appliance box, more particularly, is a kind of suction top or suspension type light fixture electric appliance box.

Background technology

Along with the product of energy-saving electric light source is introduced to the market in succession, the employed suspension type light fixture of illumination of public places such as factory building, workshop, warehouse, supermarket, market, its light source is also slightly different, is to adopt Metal halogen lamp, ceramic gold-halogen lamp, LED, high-power energy-saving lamp basically; Novel energy-conserving long-life electric light sources such as electrodeless lamp, it is required that the ballast supporting with it can not be satisfied with novel electric light source from original inductance type, so increasing electronic ballast or power supply be the output along with the output in new type electro source also, but because electric light source can produce high temperature, existing electrical wares box for lamps can be subjected to the temperature conduction of light source, make the electric ballast (power supply) of electrical wares box for lamps the inside produce high temperature, can significantly reduce the life-span of the inner electronic devices and components of electric ballast (power supply) like this, cause the fault of whole lamp.

Existing fitting structure divides two major parts usually: (one) is that electrical wares box for lamps part, (two) are source reflection lampshade parts, and wherein the electric appliance box part mainly plays two effects greatly, is respectively to settle ballast and fixing whole light fixture; As Fig. 1, a kind of existing electrical wares box for lamps, the ballast 14 that has shell is placed in the airtight electric appliance box 13, as Fig. 2, another kind of existing electrical wares box for lamps, the ballast 16 that has shell is placed in the inside of open type electric appliance box 15, as seen from Figure 1, the electric appliance box that this structure electric appliance box is sealed the heat of ballast covers, since the heat of the metal-oxide-semiconductor of ballast inside and other heating components and parts is that conduction is on the shell of ballast, but ballast shell major part is that air heat conduction is on electrical wares box for lamps, such result can cause the metal-oxide-semiconductor of ballast the inside, devices such as electrochemical capacitor are incubated by ballast shell and electrical wares box for lamps, heat does not directly loose, and makes whole electrical equipment temperature inside high, thereby significantly reduced the useful life of ballast; As seen from Figure 2, when adopting the open type electric appliance box, though the heat of ballast is not sealed shortcoming such as having brought can not waterproof, and the IP degree of protection is low, and can not using in dust, steam, the more high place of humidity; And these two kinds of structures all easily cause the temperature rise of ballast too high, because the heat of electrodeless lamp intercoupler and the heat of light source all produce in lampshade, fluorescent tube uses in lampshade for a long time, and lampshade directly is fixed on the bottom of electric appliance box, so cause this heat also can directly conduct on electrical wares box for lamps, make the ballast that is fixed in the electrical wares box for lamps increase the heat burden, cause the ballast temperature rise too high, cause electronic devices and components premature ageing or damage easily, thereby reduced the useful life of light source greatly, the universal use of more energy-conservation new light sources of more environmental protection and high-power electrodeless lamp is restricted.

Summary of the invention
