Description

The electronic ballast switch

The utility model relates to a kind of lamp switch, specifically, is the electronic ballast switch that a kind of fluorescent lamp is used.

In order to improve the condition of work of mouthful light modulation, make its energy-saving durable, people have made some novel electronic ballasts.But the electrophoretic effect that produces under DC electric field can make fluorescent lamp two ends light and shade inequality, and at present, the way one that addresses this problem is with the fluorescent tube tune, the 2nd, and additional reversing switch on ballast is as two-way double-throw six joint switches.When this switch commutates, must turn off power main switch earlier, stir reversing switch, again the energized main switch.If careless manipulation, disconnected power down source main switch just removes to stir reversing switch, is easy to make the switch sparking and even burns out.

The purpose of this utility model is to provide that a kind of structure is ingenious, dependable performance, can the extended day light modulation useful life, have the energy-saving electronic ballast switch that exchanges break-make and direct current reversing function concurrently.

For achieving the above object, the utility model adopts following technical scheme:

Mains switch and reversing switch are combined as coaxial synchronous combination switch, the switch center is the switch core of a multistage cylindrical structure, switch core core body is connected in sequence by meshing dish [15], gear [14], stem stem [22] and core print [24], has centre bore [25] in the core body; Core surface from left to right suit mains switch contact chip [13], dead ring [12], contact chip [11] and [10], dead ring [9], reversing switch contact chip [8] and [7], dead ring [6], reversing switch contact chip [5] and [4], dead ring [3], V-type contact chip [2] and reversing switch contact chip [1]; Axostylus axostyle [21] passes switch core centre bore [26], and its left end has fixedly installed control device; Contact chip [1], [4], [5], [8], [10] link to each other with voltage-multiplying circuit respectively with [13].

The gear of switch core body [14] is the anistree gear of a unidirectional rotation, and it is 45 ° and equally distributed teeth groove that there are eight inclination angles the inside of the meshing dish [15] that is used with gear [14].The control device of switch core is by drawing dish [16], push rod [18], button [17] and spring [19] to form, drawing dish [16] to be sleeved on axostylus axostyle [21] goes up and closely contacts with meshing dish [15], push rod [18] is fixedlyed connected with the dish handle [20] that draws dish [16], button [17] is installed in the top of push rod [18], one end of spring [19] is fixed on the switch bearing, the handle neck place that an end links closely and draws dish [16].Draw dish [16] double wedge to be housed, rotate so that drive meshing dish [15] by the one side of meshing dish [15].Have 4 grooves on the core body [22].

The voltage-multiplying circuit that links to each other with the contact chip of mains switch and reversing switch is two multiplication of voltage voltage triplers, is made up of C1, C2, C3, C4, D1, D2, D3 and D4.

In initial state, during the positive half cycle of electric current, current path is: [13] → [11] → [10] → D1 → D2 → [4] → [2] → [1] → Q → L → [8] → [7] → [5] → D4 → C2 → power supply.

During the electric current negative half period, current path is: C1 → D2 → [4] → [2] → [1] → Q → L → [8] → [7] → [5] → D4 → D3 → [10] → [11] → [13] → power supply.As seen, the sense of current on the fluorescent tube Q is from right to left all the time.

When switch uses, press push button [17], push rod [18] moves down, dish [16] rotation is drawn in drive, draws two double wedges on the dish right side to embed in the teeth groove of meshing dish [15], drives [15] and [14] and rotates, when forwarding 45 ° to, gear [14] just turns over a tooth pitch, and contact [13] is jumped in another groove, and 4 contacts are arranged on the mains switch contact chip [11], in 4 teeth groove of alternate embedding gear [14], 4 empty sheets of teeth groove in addition, when mains switch contact chip [13] and [11] when joining, circuit turn-on, if rotate a tooth pitch, contact [13] is jumped in the teeth groove of no contact [11], and circuit disconnects, and fluorescent tube extinguishes.

Contact chip [7] is two of annulars, and it and V-type contact chip [2] are to be embedded in the groove of switch stem stem, so can rotate synchronously with the switch core.When the switch core turns over 45 °, contact [2] also turns over 45 ° with [7], and this moment is slipped into the insulation position of no contact in the contact [4] that plays conduction commutation effect and [5], and circuit breaks.Turn over 45 ° again, mains switch contact chip [13] is jumped in the teeth groove of contact, circuit is logical, and simultaneously, contact [2] also rotates 45 ° with [7] thereupon, at this moment, contact [5] joins with the following contact of [2], and contact [4] joins with the inside contact of [7], and contact [1], [8] and [10] of annular are to be enclosed within switch stem stem surface, their ends are fixed on the printed circuit board (PCB), can together not rotate with core body.Contact [1] is tight contact with [7], [10] with [11] with [2], [8].

The switch half-twist, when the positive half cycle of electric current occurred, current path was: [13] → → [11] → [10] → D1 → D2 → [4] → [7] → [8] → L → Q → [1] → [2] → → [5] → D4 → C2 → power supply, the fluorescent tube Q sense of current is for from left to right; When the electric current negative half period occurred, the sense of current that also can analyze on the fluorescent tube Q was from left to right.Compare with initial state, the lamp tube current of flowing through is reverse.

Analyze according to this, 45 ° of the each rotations of switch core go to 360 °, have changeed a week, have changed eight states within the week, and each state is listed below:

That three times four times five times six times seven times eight times core bodys of secondary rotate 45 ° of 90 ° of 135 ° of 180 ° of 225 ° of 270 ° of 315 ° of 360 ° of lamp tube status is bright → go out → bright → go out → bright → go out → bright → go out → the light current direction right side → dextrad left side, a left side → right side, the left side right side → left-hand right side

As mentioned above,, simply solved the contradiction of current switching and direct current reversing dexterously, realized the unification of break-make and commutation pressing in the process of switch.

Compared with prior art, the utlity model has tangible advantage and effect:

1. the utility model is used alternatingly the lamp tube ends filament automatically in the switching manipulation process, has overcome the light and shade uneven phenomenon that electrophoretic effect causes, greatly prolonging lamp tube useful life.

2. adopted two multiplication of voltage voltage triplers, but low voltage starting, have energy-conservation, the characteristics that power factor is high.

3. can combine the ballast that constitutes the band reversing switch with existing fluorescent lamp iron core ballast coil, for country saves great deal of steel and copper material.

4. melt interchange break-make and direct current reversing and be one, easy and simple to handle, dependable performance.
