Description

bulb with n filaments matching holder and permutator

The utility model is supporting lighting apparatus, is applicable to the place illumination of the illuminating effect that various needs change, and can adopt in lamp kinds such as wall lamp, pendent lamp, ceiling light and desk lamp.

In actual life, people have the common illuminating effect except requiring bulb, sometimes also require bulb can send fainter even very faint light, as when seeing TV, turn on light or night WA turn on light etc. and these requirements just to be arranged in the situation; And wish that sometimes bulb has the multiple different illuminating effect stronger than general lighting effect, with should receive a visitor, the needing of differences such as many people reading, party, amusement.Existing simple illumination equipment based on single bulb can't satisfy people's above-mentioned needs.

But the purpose of this utility model provides based on a connection in series-parallel n filament bulb supporting lighting apparatus that comprises (n+1) pin socket lamp holder and n filament parallel-series switch of (n is not for containing 1 natural number and generally only getting 1 figure place), makes people can obtain the different illuminating effects of many grades of conversion from the low light level to the high light by simple regulating measure in a bulb.

The utility model is achieved in that in a bulb filament that n root that the different capacity that is suitable for rated voltage is set is connected in series, from these filaments be connected in series a little and (n+1) root lead-out wire that two end points are drawn be switched to (n+1) that be fixed on the light bulb head but individual pin to become connection in series-parallel n filament bulb; The lamp holder of pegging graft for this bulb is (n+1) pin socket lamp holder, and this lamp holder makes bulb receive n filament parallel-series switch by (n+1) root lead.Because the specific connection of (n+1) individual pin on n root filament and the light bulb head in the above-mentioned bulb, as long as we are one in the pin or some access power firestreaks, and insert the ground wire (also needing some pins sometimes) of power supply to another or other from being connected, just can obtain each root filament lights separately, careless several filament parallel connections are lighted, careless several filaments series connection is lighted and some filament mixing connection in series-parallel such as light at multiple effect, thereby satisfies the different requirements of people's different time to the light power.For example when n=3, but but connection in series-parallel n filament bulb just becomes connection in series-parallel 3 filament bulbs, Fig. 1 of its circuit figure representation such as accompanying drawing, from Fig. 1, can obviously find out, when pin 4,5 inserted live wire, the ground wire of power supply respectively, filament 1 was promptly lighted; When pin 5 access live wires, when pin 4,6 inserted ground wires, filament 1 and 2 was that parallel connection is lighted, and when pin 4,6 access live wires, when pin 5,7 inserted ground wires, three i.e. while parallel connections of filaments were lighted; When pin 4,7 inserts live wire, ground wire respectively and when pin 5,6 connected, filament 1 and 3 was promptly connected and lighted; Three filaments are connected and are lighted when pin 4,7 inserts live wire, ground wire respectively; When pin 4,7 inserts live wires, when pin 6 inserts ground wires, will make filament 1,2 series connection and again with filament 3 in parallel lighting; Or the like.Light was the most weak when wherein three filament series connection were lighted, light was the strongest when parallel connection was lighted, middle 13 class in addition: 3 grades of two filaments series connection meters, 2 grades of two a filaments series connection back and a filament and onlines, 3 grades of single filament meters, connect with a filament after the two filament parallel connections 2 grades of meters, 3 grades of two filaments and onlines.Obviously, but the connection of conversion pin just can make connection in series-parallel n filament bulb produce multiple different illuminating effect, and n filament parallel-series switch is exactly a device of realizing this conversion.

Below in conjunction with the utility model when the n=2 this specific embodiment the utility model is described in further detail.

But Fig. 2 is the structure of connection in series-parallel 2 filament bulbs, 3 pin socket lamp holders and 2 filament parallel-series switchs and connects schematic diagram.

Fig. 3 is after the pin on the light bulb head inserts the socket lamp holder, the partial enlarged drawing of the contact in pin and the socket lamp holder.

In Fig. 2, but connection in series-parallel 2 filament bulbs 10 with filament 8 and 9 be plugged on the 3 pin socket lamp holders 11, three lead-out wires of lamp holder are connected to respectively on the wiring point 12,13 and 14 of 2 filament parallel-series switchs 24.In 2 filament parallel-series switchs 24, wiring point 12,13 with 14 respectively with near touch article 15 and touch article 16 and be distributed in position 17 18,19 and 9 contacts of 20 just like being connected shown in the figure dotted line, touch article 15 and touch article 16 are to receive respectively on the live wire of power supply and the ground wire; Also be provided with in the switch one can slidably reciprocate on the direction parallel with touch article and can on the positions such as 17,18 topped on it the contact and the slide block 23 of touch article, conducting strip 21 and 22 are housed on the slide block 23, when topped locational contact of slide block and touch article, two conducting strips can make corresponding contacts and the two connection of touch article that is close to setting respectively.So when slide block 23 was in position 17, wiring point 13,14 was promptly connected with the power firestreak ground wire respectively, filament 8 and 9 is lighted by series connection; When slide block 23 slided into position 18, wiring point 12,14 was received live wire, ground wire respectively, and filament 8 is lighted; When slide block 23 slided into position 19, wiring point 12,13 was received live wire, ground wire respectively, and filament 9 is lighted; When slide block 23 slided into position 20, wiring point 12 was access in live wire, and wiring point 13,14 is access in ground wire, and filament 8 and 9 parallel connections are lighted; Be in the centre that put at the two-phase ortho position in above four positions and work as slide block, bulb promptly cuts off the power supply and does not work.

By diagram as seen, along with the slip of slide block 23 in the switch 24, just can obtain four kinds of different illuminating effects, like this by position 17 to 20, by the simple adjustment on switch, a bilux bulb can use as four single filament bulbs.If bulb adopt 3 filaments 4 filaments or the like, a bulb has just had the effect of more than 10 single filament bulb so.

For making bulb insert unlikely natural slippage behind the socket lamp holder, such several annular grooves shown in each pin on the light bulb head all is carved with among Fig. 3 on the pin 25, like this, pin just can be bitten stinging formula contact 26 by the elasticity in the socket lamp holder after inserting the socket lamp holder, is difficult for getting loose.

The switch 24 of Fig. 2 is owing to be that the connection in series-parallel that is fit to 2 filaments is changed, certainly the situation that is connected so there are not two pins not connect power supply, will occur in the parallel-series switch more than 3 filaments that some pins need not connect power supply and the situation that is connected certainly, this can take starting to exchange fire, the folded centre position of two touch articles of ground wire is set up some contacts and is realized in order to the way of receiving on the pin that need to link to each other and set up the 3rd conducting strip in the folded centre position of two conducting strips of slide block.

In n filament parallel-series switch, when n numerical value was big, its class also requires a lot, and was unlikely too complicated for making switch, and general visual concrete condition is selected some practical class settings.About the pattern of switch, Fig. 2 only relates to the slide block slidingtype, certainly, in fact also can adopt knob.Piano type or the like pattern, but its operation principle remains identical.

Be also pointed out that, n filament parallel-series switch also can obtain to use in the control of bull wall lamp, bull pendent lamp and the many lamps of discrete etc.: as long as n bulb is together in series, again receiving n filament parallel-series switch from (n+1) root lead-out wire that is connected in series a little and end points is drawn, just can on a switch, realize conversion brightness adjustment control, thereby make original light fixture obtain new performance many lamps.
