Abstract

Plastic upper cover for one kind of energy-saving lamp, comprising of lamp head (1) and main body (2) two parts, heat radiation hole (3) arraying in radiation which takes lamp head (1) as the center of circle is set on main body (2), dustproof strip which two ends are connected with two ends of the hole (3) is set on right low direction, width of dustproof (4) is same as that of heat radiation hole (3), total number is also same. The upper cover (5) consists plastic integer of energy saving lamp with mediate partition ring (6), low base seat. Compared with existed technology, the utility model has the advantage of improving draw strength of energy saving plastic parts and dustproof function.

Description

The Electricity-Saving Lamp Moulds One loam cake

Technical field

The utility model relates to a kind of loam cake of working of plastics of electricity-saving lamp, is the improvement to the louvre of loam cake.

Background technology

Electricity-saving lamp is because of the difference of its fluorescent tube form, and it is multiple to be divided into U-shaped, H shape, Double-spiral etc., no matter the electricity-saving lamp of which kind of form with regard to whole lamp, is made up of lamp holder, plastic, fluorescent tube, electric ballast and lead.In recent years popular plastic from top to bottom mainly contains loam cake, middle spacer ring, lower bottom base three parts, electric ballast is installed in the loam cake, be heat generating components, fluorescent tube is installed on the lower bottom base, also is heat generating components, therefore, louvre is all arranged on loam cake and the lower bottom base, on the middle spacer ring air vent is arranged, finish the heat radiation task of whole lamp jointly, to prolong the service life of lamp.The louvre of loam cake is discontinuous circumferential arrangement around lamp holder in the prior art, is narrow arcuate socket, and this has dissection concerning the downward whole lamp of gravity, and the intensity infringement is bigger, and dust easily enters, and hinders the life-span of lamp.

Summary of the invention

The purpose of this utility model is the above-mentioned deficiency at prior art, and it is little to design a kind of intensity infringement to whole lamp, can partly stop the Electricity-Saving Lamp Moulds One loam cake that dust enters.

The purpose of this utility model can realize by following measure: it is made up of lamp holder and main body two parts, and having on the main body with the center of circle of lamp holder is the radial louvre at center.

The also available following measure of the utility model comes perfect: the dust excluder that has two ends to link to each other with the two ends of louvre under the radial louvre; Dust excluder equates with the width of corresponding louvre; Dust excluder equates with the louvre sum.

Description of drawings

Fig. 1 is the utility model structural representation

Fig. 2 is the vertical view of Fig. 1.

Fig. 3 is the A portion enlarged drawing of Fig. 1

Fig. 4 is a kind of overall structure figure of Electricity-Saving Lamp Moulds One.

The specific embodiment

The utility model is described in further detail below in conjunction with embodiment and with reference to accompanying drawing.

As shown in Figure 4, Electricity-Saving Lamp Moulds One is made by engineering plastics, consists predominantly of loam cake 5, middle spacer ring 6, lower bottom base 7 three parts have air vent 8 on the middle spacer ring 6, and louvre 9 is arranged on the lower bottom base 7, the bottom of lower bottom base 7 is the fluorescent tube installation portion, in the loam cake 5 electric ballast is installed.

Can find out that from Fig. 1 and Fig. 2 the louvre 3 on the loam cake 5 is that the center of circle with lamp holder 1 is that radial arrangement is made at the center, loam cake 5 is not caused the annular cutting, can not have a strong impact on the tractive intensity of loam cake 5.Louvre is made the narrow arcuate socket of discontinuous circumferential arrangement around lamp holder in the prior art, though be unlikely to cause breaking of lamp to fall, with regard to design concept, is wrong.

Fig. 3 amplifies the A portion of Fig. 1, and having shown under the louvre 3 has dust excluder 4, and it is to make mould according to designing requirement, during production, passes through injection molded.Therefore inevitable width equates, sum also equates.

The utility model has the tractive intensity that improved loam cake and the advantage of dustproof effect compared to existing technology.

Claims

1, a kind of Electricity-Saving Lamp Moulds One loam cake is made up of lamp holder (1) and main body (2) two parts, and it is characterized in that having on the main body (2) with the center of circle of lamp holder (1) is the louvre that is radial arrangement (3) at center.

2, Electricity-Saving Lamp Moulds One loam cake as claimed in claim 1, it is characterized in that said radial louvre (3) under have two ends to link to each other with the two ends of hole (3) dust excluder (4).

3, Electricity-Saving Lamp Moulds One loam cake as claimed in claim 1 or 2 is characterized in that said dust excluder (4) equates with the width of corresponding louvre (3).

4,, it is characterized in that said dust excluder (4) equates with the sum of louvre (3) as each described Electricity-Saving Lamp Moulds One loam cake among the claim 1-3.
