Embodiment
For further specifying above-mentioned purpose of the present invention, technical scheme and effect, in conjunction with above-mentioned each figure the present invention is described in detail by the following examples.
See also Fig. 7, shown in Figure 8, high-pressure sodium ballast for lamp 20 of the present utility model comprises magnetic core 21, yoke 22, choking-winding 23.
Described magnetic core 21 is that a center has boss 211, " return to type " body of side 212 is set all around, the boss 211 of " returning type " body with form groove 213 all around between the side 212, upper surface opening, the lower surface of " returning type " body are sealed.
Described choking-winding 23 is stacked in the groove 213 of the boss of magnetic core and side formation all around.
Described yoke 22 is covered on the upper surface of magnetic core 21.
The side is and faces directly around Fig. 7, the magnetic core 20 illustrated in Figure 8, and 214, four breach 214 of four diagonal angle leaving certain gaps uncovered by the economic plans of magnetic core 20 can be symmetrical arranged also and can asymmetricly be provided with.Choking-winding 23 also is square, so that place in the groove 213.Middle boss 211 can be designed to cannular boss.
Correspondingly, the horizontal cross-section of yoke 22 then is one " cross " type, and it just in time can be covered on the magnetic core 21, also leaves the breach 221 of symmetry or asymmetric setting at four diagonal positions of yoke 22, and breach 221 is corresponding with magnetic core 21 breach 214.When making magnetic core 21 and yoke 22, yoke 22 and magnetic core 21 can be divided into the shape of Figure 10, Figure 11 respectively, be convenient to technologic processing and making like this, magnetic core 21 forms by some vertical silicon steel thin slices are folded mutually, equally, yoke 22 also forms by some vertical silicon steel thin slices are folded mutually.
After with magnetic core 21, yoke 22, choking-winding 23 assemblings, can form the ballast 20 that high-pressure sodium lamp is as shown in Figure 8 used.
For such ballast, all choking-windings 23 almost are covered by in magnetic core 21, the yoke 22, have accomplished " magnetic circuit encirclement circuit " basically, please again referring to shown in Figure 9, the dotted line of band arrow is the magnetic line of force 25 directions among the figure, and the loss of the magnetic line of force 25 is few, thereby leakage field is also little.The magnetic line of force 25 is not waste basically, and be not fully utilized unlike the magnetic line of force of the side of traditional ballast, obviously, ballast of the present utility model does not have the leakage field phenomenon basically, from faraday's formula V=-N (d Φ/dt)=-NBA ω can prove the conversion efficiency of ballast of the present utility model
In the formula, the voltage of V for producing, N is a coil turn, the magnetic field of d Φ/dt for changing, B is a magnetic field intensity, A is the magnet sectional area,
Hence one can see that: voltage V is directly proportional with the product of magnetic field intensity B, magnet sectional area A, voltage is directly proportional with the number of turn of coil, under the situation of the elementary or secondary voltage of setting, the product of the number of turn of coil and the sectional area of magnetic core is the constant of a design, magnetic field intensity is big more, and the voltage that is produced, electric current are big more, and the magnet sectional area is big more, the voltage that is produced, electric current are also big more, and the magnetic conversion efficiency is also high more.
As another embodiment, the side of " return to type " body of magnetic core is arc surface, magnetic core prolong the breach that diametric four diagonal angles leave symmetry or asymmetric setting.The shape of yoke is in the form of annular discs, and diametric four diagonal angles that prolong of yoke also leave symmetry or asymmetric breach, and this breach is corresponding with the breach on the magnetic core.
Because based on the similar structure of the ballast of last embodiment, this embodiment illustrates with regard to figure of no use.
Certainly, in this embodiment, it is cylindric that the magnetic core boss then is, and boss can be designed to cannular boss, forms circular groove between the side of magnetic core and the boss,
Correspondingly, described choking-winding is then rounded.
When making,
Described magnetic core also forms by some vertical silicon steel thin slices are folded mutually;
Described yoke also forms by some vertical silicon steel thin slices are folded mutually.
With the ballast example that the 400W high-pressure sodium lamp of Philips company product is used, compare with ballast of the present utility model, the new advantage that has of this practicality is described:
The Philips product
Power is 400W, and weight is 4575 grams, and power consumption is smaller or equal to 9%, and temperature rise is smaller or equal to 70 ℃.
The utility model product
Power is 400W, and weight is 3500 grams, and power consumption is smaller or equal to 8%, and temperature rise is smaller or equal to 70 ℃.
On cost, the latter compares with the former, has reduced more than 20%.
By above parameter as can be seen, under the situation of the equal brightness of high-pressure sodium lamp and under the constant situation of other performance index of ballast, the weight of ballast of the present utility model reduces greatly, and this more can further specify the superiority of the utility model ballast.
Ballast of the present utility model can be according to above-mentioned thought, the magnetic core and the yoke design of ballast can be taken on a different shape, certainly, those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the utility model, and be not to be used as qualification of the present utility model, as long as in connotation scope of the present utility model, all will drop in the scope of the utility model claims variation, the modification of the above embodiment.
