The specific embodiment
Fig. 2 illustrates the diffuser support frame of the light fixture of the utility model one embodiment.Shown in figure 2, the diffuser support frame 200 of the light fixture of embodiment, comprises a plurality of support bars 210.These support bars 210 are bonded into support frame 200.In the present embodiment, support frame 200 is rectangle.Yet be appreciated that support frame 200 also can other polygon, such as triangle, pentagon etc.In the present embodiment, these support bars 210 are straight.Yet be appreciated that these support bars 210 can be also crooked.Therefore support frame 200 can be by the shape after each spring song on polygon basis.
Support frame 200 after joint forms interior profile, for example an inner polygon.More particularly, be interior rectangle 201 as shown in Figure 2.Diffuser 300 (with reference to figure 6) will be placed in this interior profile, and the edge of diffuser 300 is by each support bar 210 carryings of support frame 200.
Fig. 3 illustrates the stereogram of a support bar of support frame shown in Fig. 2.Fig. 4 illustrates the sectional view of a support bar of support frame shown in Fig. 2.Shown in figure 3-4, each support bar 210 is integrally formed.Support bar 210 comprises main part 211, the first turning point 212, the second turning point 213 and folding portion 214.The first turning point 211 extends upward from a side of main part 211.Folding portion 214 is rolled over to this rollover from the opposite side of main part, thereby is formed for carrying the load bearing seat 215 of diffuser.The second 213 of turning points are to continue to extend upward from folding portion 214.The first turning point 211 is preferably vertical with main part 211.Folding portion 214 is superimposed with a part for main part 211 substantially.The second turning point 213 is also preferably vertical with main part 211.In this structure, as the load bearing seat 215 of diffuser, be jointly to be supported by main part 211 and the two-part material of folding portion 214, so its intensity is improved.
By the support bar shown in Fig. 3-4, the support frame shown in composition diagram 2 200 easily, and without carrying out again complicated welding.Therefore the manufacture process of the support frame 200 of the present embodiment is more simple, and quality conformance is better.
Shown in figure 3, the main part 211 of each support bar 210 is preferably inclined to acute angle at two ends.Facilitate like this each support bar 210 to splice at joint.
Shown in figure 4, in one embodiment, the width of main part 211 is 35-50mm.The height of the first turning point 212 is 10-25mm.The width of folding portion 214 is 8-12mm.Whole support bar is 0.8-2mm at the thickness of each position.Test shows, such design can take into account the balance of intensity and material usage.
Fig. 5 illustrates the local S enlarged drawing of support frame shown in Fig. 2.Shown in Fig. 2 and Fig. 5, at the joint of every two adjacent supports bars 210, the folding portion 214 of adjacent supports bar 210 is spliced into a sealing 203.Each sealing 203 is relative with each interior angle 202 of the interior rectangle 201 of support frame 200.
For instance, in adjacent two support bar 210a and 210b, the end of the folding portion 214a of the first support bar 210a has the convex extension part 216 of the inner side edge extended line B that exceeds the second support bar 210b.The end of the folding portion 214b of the second support bar 210b is concordant with the inner side edge extended line A of the first support bar 210a.The end splicing of convex extension part 216 on the folding portion 214a of the first support bar 210a and the folding portion 214b of the second support bar 210b, forms aforesaid sealing 203.That is to say, in this example, the convex extension part in the folding portion of a main wherein support bar by two adjacent support bars forms sealing.
But be appreciated that in another embodiment, the convex extension part in the folding portion of each support bar that also can be by adjacent supports bar forms sealing.Specifically, as shown in Figure 6, in adjacent supports bar 210a, 210b, the end of the folding portion 214a of the first support bar 210a has the first convex extension part 216a of the inner side edge extended line B that exceeds the second support bar 210b.The end of the folding portion 214a of the second support bar 210b has the second convex extension part 216b of the inner side edge extended line A that exceeds the first support bar 214a.The first convex extension part 216a and the second convex extension part 216b splicing, form sealing 203.In this connecting method, the first convex extension part 216a and the second convex extension part 216b are acute angle.Connecting method is similar to the mode of the main part splicing of two adjacent supports bars.
The effect of above-mentioned sealing 203 is to form sealing at the joint of every two adjacent supports bars 210.With reference to shown in figure 7 support frame place the schematic diagram of diffuser, diffuser 300 is placed on support frame 200, and sealing strip 310 is set under diffuser 300, the edge of diffuser 300 arranges pressing plate 320.It under sealing strip 310, is exactly the sealing 203 of two adjacent supports bar 210 joints.The breach can shutoff originally staying at two adjacent supports bar 210 joints by sealing 203, forms complete sealing.
Diffuser support frame of the present utility model can be used on various suitable light fixtures.The shape of support frame can change to adapt to the shape of light fixture.In addition, this diffuser support frame can be applied in the light fixture in various lamps source, such as fluorescent lamp, Halogen lamp LED, fluorescent lamp, LED light lamp etc.
In sum, the diffuser support frame of the utility model embodiment, by the unique design of support bar, the manufacture process of whole support frame is simplified, and quality conformance is better.And the diffuser support frame of the utility model one embodiment, by the design of support bar joint sealing, has improved sealing effectiveness.
Although the utility model is described with reference to current specific embodiment, but those of ordinary skill in the art will be appreciated that, above embodiment is only for the utility model is described, in the situation that not departing from the utility model spirit, also can make variation or the replacement of various equivalences, therefore, as long as the variation of above-described embodiment, modification all will be dropped in the application's the scope of claims within the scope of connotation of the present utility model.
