Abstract

The utility model discloses an electronic ballast for fluorescent lamps. The inner cavity of a shell made of aluminum alloy sections is hollow; electronic ballast components are connected to the cavity of the shell; two end plugs are respectively connected to both ends of the shell; the side faces of the end plugs are provided with through holes for connecting the electronic ballast components. Because the stretching aluminum alloy sections are used as the shell, the wall thickness is generally selected between 0.8 and 1.2 mm. The electronic ballast for fluorescent lamps effectively utilizes the favorable heat conducting and heat radiating performance of the outer side faces of the aluminum alloy shell, and prolongs the service life of the electronic ballast for fluorescent lamps and has safe utilization.

Description

Electronic ballast for fluoresent lamp

The utility model relates to fluorescent light fittings, is specifically related to a kind of electronic ballast for fluoresent lamp.

At present, the housing of the electronic ballast for fluoresent lamp that uses in the society is by last, after lower house fastens, the electronic ballast parts are included in its inner chamber to be constituted, on, lower house is all taked the injection moulding of ABS engineering plastics, and on upper shell, have an air-vent, though this mode produces scattering and disappearing of heat when helping the work of electronic ballast parts, but in the more abominable occasion of work situation (as furniture factory, the cotton mill, when using fluorescent lighting the clothing factory), the very easy dust that falls in the air that makes, wood chip, the cotton spinning titbit is blocked the air-vent of its ballast upper casing, cause the ballast radiating condition poor on the contrary, the lighter burns ballast, weight person also easily causes fire incident, poor safety performance by burning of ballast.In addition, its heat-resisting anti-aging degree of upper and lower casing of making of ABS engineering plastics is poor.

Task of the present utility model is to provide a kind of compact conformation, and radiating condition is good, and security performance is strong, the electronic ballast for fluoresent lamp of long service life.

Task of the present utility model realizes by following scheme: the housing inner chamber of being made by aluminium alloy extrusions is a hollow form, the electronic ballast parts are connected in the chamber of housing, 2 plugs are connected in the two ends of housing respectively, and the plug side is provided with the through hole that connects the electronic ballast component leads.

Because the utility model is to adopt stretching all-in-one-piece thin-walled hollow form aluminium alloy extrusions as housing, the electronic ballast parts are inserted its inner chamber hermetically sealedly, remove and dwindled overall dimension than the ballast housing of original engineering plastics injection moulding, also effectively utilize the heat conductivility heat radiation well of Al-alloy casing lateral surface, prolonged useful life of electronic ballast for fluoresent lamp and safe and reliable.

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.

Fig. 1 is first kind of embodiment cutaway view;

Fig. 2 is that Fig. 1 has the cut-away section vertical view;

Fig. 3 is second kind of embodiment cutaway view;

Fig. 4 is that Fig. 3 has the cut-away section vertical view.

Embodiment one, with reference to Fig. 1-Fig. 2.Power is that its length * wide * high overall dimension of electronic ballast for fluoresent lamp of 20W or 40W is: 130 * 36 * 25 (mm).Housing 3 is to adopt the aluminium alloy extrusions that stretches to make, and its inner chamber is a hollow form, dispels the heat fully for utilizing the Al alloy shell body side surface, and the wall thickness of its inner chamber is typically chosen in 0.8-1.2mm; Present embodiment is 0.8mm.Electronic ballast parts 4 are connected with the connecting plate of 2 plugs 2 that connect housing 3 two ends.Plug 2 adopts fire proofing and engineering plastics mixed injection molding to form, and is provided with the through hole that connects electronic ballast component leads 1 on plug 2 sides, and is easy to operate for connecting lead, can be provided with 1-4 through hole on plug 2 sides, and present embodiment is 2 through holes.

Embodiment two, with reference to Fig. 3-Fig. 4.What present embodiment and embodiment one were different is: the housing 3 that the aluminium alloy extrusions of stretching is made is trapezoidal shape; 2 plugs 2 also are to adopt aluminium alloy extrusions to make, and it is one that right-hand member plug 2 sides are provided with the through hole that connects electronic ballast component leads 1.

The utility model in use, the semicircular croze that is provided with by plug 2 is connected on the fluorescent lamp shade, the lead 1 of right-hand member is connected in outside line 220V power supply, the lead 1 of left end is connected in the terminals at fluorescent tube two ends respectively.The utility model also can be designed to the specification of different sizes according to the needs of different capacity fluorescent lamp.
