Abstract
The invention discloses an LED energy-saving lamp magnetic core which comprises a center post and a framework and is characterized in that the cross section of the magnetic-core central column is elliptical. According to the LED energy-saving lamp magnetic core provided by the invention, through changing the shape of the magnetic core center post sectional area, under the condition of the same magnetic-core size, the sectional area is increased, the output power is improved, and the luminous flux of the energy-saving lamp is increased; the magnetic core size is smaller and the material is saved with the same output power; when the center post sectional area is not changed, through the arc design on the framework, the window area is effectively added, more coils can be wound or the sectional area of the coil is increased; and accordingly, waste is reduced, the output power is improved, and more effective energy-saving purpose is achieved.
Description
Technical field
The present invention relates to a kind of core structure, relate in particular to a kind of LED electricity-saving lamp magnetic core.
Background technology
LED electricity-saving lamp of the prior art generally adopts E type magnetic core, and it is circular or square that the cross section of newel is generally, and the skeleton and the gap between the center pillar of both sides are window; Under the certain situation of magnetic core skeleton structure; Sectional area and window area mutual restriction, sectional area is big more, and then window area is more little.Magnetic core center pillar sectional area is big more, and magnetic flux is big more, and power output is also big more; And window area is big more, then can be around more coil, or increase the sectional area of coil, and reduce loss, improve delivery efficiency.But because of sectional area and window area mutual restriction, therefore, power output and delivery efficiency are difficult to take into account.
Summary of the invention
Technical problem to be solved by this invention provides a kind of LED electricity-saving lamp magnetic core, when improving LED electricity-saving lamp power output, can improve delivery efficiency, makes the LED electricity-saving lamp brighter more energy-conservation.
For solving the problems of the technologies described above, the present invention provides a kind of LED electricity-saving lamp magnetic core, comprises center pillar and skeleton, it is characterized in that, the core center column section is oval.
Said magnetic core is an E type magnetic core.
Said skeleton is protruding to the direction away from said center pillar towards the face of said center pillar.
Said skeleton is an arcwall face towards the face of said center pillar.
The beneficial effect that the present invention reached:
LED electricity-saving lamp magnetic core of the present invention through changing the shape of magnetic core center pillar sectional area, can increase sectional area under the identical situation of core volume, improved power output, has increased the luminous flux of electricity-saving lamp; When reaching identical power output, core volume is littler, has practiced thrift material.When the center pillar sectional area is constant,, can increase window area effectively through the arc on skeleton design, can be around more coil, or increase the sectional area of coil, and reduce loss, improve delivery efficiency, more energy-conservation.
Description of drawings
Fig. 1 is one embodiment of the invention structural representation;
Fig. 2 is the cross-sectional view of Fig. 1;
Fig. 3 is another embodiment of the present invention cross sectional representation.
Embodiment
Below in conjunction with accompanying drawing the present invention is further described.Following examples only are used for technical scheme of the present invention more clearly is described, and can not limit protection scope of the present invention with this.
Embodiment 1
Like Fig. 1, shown in Figure 2, LED electricity-saving lamp magnetic core of the present invention comprises center pillar 1, skeleton 2, and the cross section 11 of center pillar 1 is oval by common circle, squared design, and core volume, the situation lower section that window 4 areas are identical amass bigger, have improved power output.
With a power is that the LED electricity-saving lamp of 28W is an example; When reaching identical luminous flux and being 100 lumens (Lm), adopt same core material, the core material quality that core structure of the prior art needs is 20g; And adopt core structure form of the present invention; Only needing the core material quality is 15g, has significantly reduced the use amount of core material, and the volume of magnetic core is littler.Under the situation that if core material is identical, volume is identical, core structure of the present invention compared with prior art, sectional area is bigger, power output is bigger, power output can improve more than 40%.
On the basis of embodiment 1, present embodiment is under the constant situation of magnetic core sectional area 11, with being arranged to arc towards two sides 3 of center pillar 1 in the skeleton 2; The direction towards away from center pillar 1 of arc is protruding; Window area 4 is increased, as shown in Figure 3, identical with embodiment 1 in fact.
After window area 4 increases, on the magnetic core around winding wire directly increase, impedance reduces, loss reduces, and has improved delivery efficiency, delivery efficiency can be brought up to more than 90%.Realized when increasing power output, can improving delivery efficiency, made the LED electricity-saving lamp brighter, more energy-conservation.
It will be appreciated by those of skill in the art that core structure of the present invention not only can be applied on the magnetic core of LED electricity-saving lamp, can also be applied to can increase power output in the magnetic core of other transformers equally, reduces loss, improves delivery efficiency.
The above only is a preferred implementation of the present invention; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from know-why of the present invention; Can also make some improvement and distortion, these improvement and distortion also should be regarded as protection scope of the present invention.
