Abstract
The utility model provides a shell is moulded to electricity-saving lamp, belongs to the illumination field, including the epitheca and the inferior valve of overlap joint each other, the upper portion of epitheca can install screw socket formula or bayonet lamp holder, and inside is equipped with the ballast to on installing a circuit board with it, the fluorescent tube can be installed to the inferior valve, and the epitheca also can be opened has the louvre, and the outside of inferior valve and the inboard of epitheca are equipped with a plurality of passageways of ventilating at the overlap joint position. The opened air channel obviously improves the heat dissipation function, and the structure is simpler, only two plastic parts of the upper shell and the lower shell are provided, so that the cost is lower, the operation is simpler, and the automatic production is easy to realize.
Description
Technical field
The utility model belongs to lighting field, specially refers to a kind of electricity-saving lamp and moulds shell.
Background technology
Electricity-saving lamp is moulded the high temperature in the shell, is very big threat to the life-span and the operate as normal of ballast electronic component, more existing for this reason improvement projects.Commonly open louvre in the place of moulding the close lamp holder of shell, the more common way of another one is to take provision for thermal insulation with the caloric value of fluorescent tube and the zone isolation of ballast.Although have louvre in the place near lamp holder, because other positions do not have perforate, the hot-air in the plastic housing is difficult to the cold air exchange with the outside, and in fact the effect of the louvre of being opened can not be brought into play well.Though in utility model patent (ZL02219570.X), mention and can solve heat dissipation problem preferably, increase by 1～2 heat insulating member, thereby cause complex structure, cost is higher, assembles loaded down with trivial detailsly, and it is longer to mould total overall dimension of shell.
Summary of the invention
The utility model technical issues that need to address are, in prior art, take cooling measure ineffective to the condition of high temperature of moulding in the shell, effect is not good enough, can't solve the problem of moulding air flows in the shell, do not reach the purpose of cooling yet,, not only solve heat radiation so need a kind of shell of moulding of design, and claimed structure is simple, cost is low, and is easy and simple to handle, to realize reducing temperature in the shell.
In order to reach the purpose of this utility model, finish by the following technical solutions, a kind of electricity-saving lamp is moulded shell, comprises the upper casing and the lower casing of mutual overlap joint, and screw type or bayonet cap can be adorned in the top of upper casing, ballast is equipped with in inside, and with on wiring board of its device, lower casing can be adorned fluorescent tube, and upper casing also can have louvre, it is characterized in that the outside of lower casing and the inboard of upper casing are provided with the passage of a plurality of ventilations at overlapping part.
Contact with the lower casing outer at position, the outer of described ballast circuit plate has similar shape.Mould shell for circle, the cross section of said venting channels is arc substantially.For the non-circular shell of moulding, perhaps in order to increase the sectional area of venting channels, the cross section of said a plurality of venting channels is inside recessed concave shaped.Regardless of the shape in the cross section of venting channels, the optimal number of said a plurality of venting channels is 2 to 4, and its position is arranged on the filament part away from fluorescent tube as far as possible.For arc venting channels brace rod can be arranged.
During actual the use, in most cases be fluorescent tube down, the hot-air in the upper casing is gently discharged from the perforate of upper casing because of proportion, colder air covers from the passage of bottom ventilation around simultaneously, moulds the shell temperature inside thereby reduced.If fluorescent tube uses up, then hot-air is discharged from the passage of ventilation, cold air near the perforate the lamp holder mend into.When level or other direction are used, because all venting channels and perforates can not fully on a horizontal plane exchange of inner air and outer air can take place also.
The beneficial effects of the utility model are, the gas passage of opening has obviously improved heat sinking function, and it is relatively simple for structure, has only two plastics of upper casing and lower casing, and cost is lower, operate simplyr, also easily are automated production.

Fig. 1 is the front view of an embodiment, also is the B-B partial sectional view of Fig. 2;
Fig. 2 is that the A-A of Fig. 1 is to view;
Fig. 3 is the cross-sectional view of Fig. 1 venting channels;
Fig. 4 is the cross-sectional view that a kind of venting channels is added with the embodiment of brace rod;
Fig. 5 is the cross-sectional view that a kind of non-circle is moulded the venting channels of shell embodiment.
Embodiment
Referring to Fig. 1, Fig. 2, Fig. 3, a kind of electricity-saving lamp is moulded shell, the upper casing 1 and the lower casing 2 that comprise mutual snapping (overlap joint that the band convex-concave interlocks), lamp holder 3 is equipped with on the top of upper casing, ballast 4 is equipped with in inside, lower casing can be installed fluorescent tube 5, and upper casing has louvre 6, and the inboard of the outside of lower casing 2 and upper casing 1 is provided with the passage 7 of ventilation at fastening position.
Contact with the lower casing outer at position 9, the outer of ballast circuit plate 8 has similar shape, and 9 belows, contact site also are provided with boss 11, can reduce fluorescent tube the hot-air here so as far as possible and pass to ballast this way.
The cross section of venting channels 7 is arc 10 for what surrounded by straight line and circular arc, and the shape of ballast circuit plate helps processing like this.
The quantity of venting channels 7 is 2, can certainly be 1,3 or 4, and as far as possible away from the filament part of fluorescent tube, because temperature herein is very high, prevents that hot-air from entering.
Boss 11 plays supplemental support, prevents that upper casing 1 and lower casing 2 from damaging when exerting oneself excessive snapping to some extent, limits simultaneously and leaves necessary gap between upper casing 1 and the lower casing 2.
Referring to Fig. 4, when the oversize or quantity of venting channels 7 and arc 10 more for a long time, be easy to generate strain and cause that tightening force weakens between upper casing 1 and the lower casing 2, therefore need increase brace rod 12 at the venting channels place, brace rod 12 can be opened and also can open on lower casing 2 on the upper casing 1.
Referring to Fig. 5, be another embodiment, it is non-circular moulding shell, the cross section of venting channels is inside recessed concave shaped 13.
