Abstract
The utility model relates to a series lamp which comprises a plurality of lamps which are connected in series, wherein the series lamp is powered by alternating current; at least one lamp is connected in parallel with an inductor; and a resistance value of the inductor is greater than or equal to 20 ohm. Each lamp or at least partial lamps of the series lamp is or are connected in parallel with the inductor or the inductors; and when one or more lamps connected in series fall off or are burnt, the inductors originally connected in parallel with the lamps are connected in series in a circuit, and transmit alternating current to other lamps connected in series, so that a whole loop is switched on continuously, and the rest of the lamps are not turned off.
Description
Technical field
The utility model relates to a cluster of lamps, ornamental.
Background technology
A cluster of lamps, ornamental is widely used in the indoor and outdoor and decorates, and is the indispensable ornament of celebrating red-letter day.A cluster of lamps, ornamental mainly refers to be connected on a lamp decoration in the electric loop.Series lamp generally comprises the lamp that is together in series more than 10 at least, and the supply voltage of a cluster of lamps, ornamental is generally civil power, and the voltage that is assigned on each lamp also lies prostrate with regard to 1.5V to 25V().But when energising, be easy to generate surge current in the circuit, easily burn bulb.And in the series connection bulb, have one or several bulb to come off or burn, can cause entire circuit to open circuit again.
Summary of the invention
The purpose of this utility model be to provide a kind of bulb to come off or when burning circuit continue path, and can absorb surge current, thereby reduce surge current to the cluster of lamps, ornamental of the impact of lamp.
An a kind of cluster of lamps, ornamental comprises a plurality of lamps of being connected in series, and this cluster of lamps, ornamental is by AC-powered.Be parallel with inductance at least one lamp, the resistance value of described inductance is more than or equal to 20 ohm.
Preferably, a described cluster of lamps, ornamental also comprises a resistance of being connected in series with described inductance, and described inductance and the series arm of described resistance composition are connected in parallel on the two ends of corresponding lamp.
Preferably, a described cluster of lamps, ornamental also comprises a diode that is connected in parallel with described inductance.
Preferably, described inductance comprises magnetic core and is wound in resistance wire on the magnetic core.
Preferably, all be parallel with an inductance on each lamp.
Preferably, each lamp includes bulb and reaches the fixedly lamp socket of bulb, is provided with the metal terminal that can be electrically connected with the lamp base of bulb in the lamp socket; Described inductance is fixed in the described lamp socket, and is electrically connected with described metal terminal.
All be parallel with inductance on each lamp of the utility model cluster of lamps, ornamental or at least part of lamp, when series lamp have one or more come off, burn after, originally be connected in parallel under the lamp inductance and become and be connected in the circuit, be other series lamp alternating current stream, continue to keep the conducting of whole loop, all the other lamps do not extinguish.

The specific embodiment
Below in conjunction with specific embodiment and accompanying drawing the utility model cluster of lamps, ornamental is described in further detail.
Fig. 1 is the circuit theory diagrams of the cluster of lamps, ornamental of the utility model embodiment one, and wherein a cluster of lamps, ornamental mainly comprises a plurality of lamps 3 of being connected in series by electric wire 2, and these lamps 3 are by power supply 1 power supply.Power supply 1 is alternating current.Lamp 3 can be tengsten lamp, also can be the LED(light emitting diode) lamp.Because the rated voltage of these lamps is lower, be generally the 1.5V(volt) to 25V, therefore the bulb number that comprises of a cluster of lamps, ornamental is no less than 10 at line voltage during for 220V.In the present embodiment, all be parallel with an inductance 4 on each lamp 3.The resistance value of inductance 4 is not less than 20 ohm, adopts 40 ohm in the present embodiment.So, one or morely come off, burn when series lamp 3 has, be connected in parallel on high value inductance 4 under the lamp 3 originally and become and be connected in the circuit, be other series lamp conductive electric current, continue to keep whole return path, all the other lamps do not extinguish.Among other embodiment, can only have to be parallel with inductance 4 on the part lamp 3.
As shown in Figure 4, in the present embodiment, lamp 3 comprises bulb 31 and the fixing lamp socket 32 of bulb, is provided with the metal terminal that is electrically connected with the bulb lamp base in the lamp socket 32 as electric-conductor 7.Inductance 4 is fixed in the lamp socket 32, is connected across on the electric-conductor 7 to realize in parallel with bulb 31.Preferably, inductance 4 comprises magnetic core and is wound in resistance wire on the magnetic core that resistance wire is terminal to be electrically connected with electric-conductor 7.
Fig. 2 is the circuit theory diagrams of the cluster of lamps, ornamental of the utility model embodiment two, the difference of embodiment two and embodiment one be also to comprise one with inductance 4 diode connected in parallel 5.This circuit working principle is identical with embodiment one, and diode 5 plays the effect of pressure limiting, current limliting.
Fig. 3 is the circuit theory diagrams of the cluster of lamps, ornamental of the utility model embodiment three, the difference of embodiment three and embodiment one is also to comprise a resistance 6 that is connected in series with inductance 4, the series arm that inductance 4 and resistance 6 are formed is connected in parallel on the two ends of lamp 3, and this circuit working principle is identical with embodiment one.Resistance 6 plays the effect of current limliting, pressure limiting.
Though description of the present utility model is carried out in conjunction with above specific embodiment,, those skilled in the art that can carry out many replacements, modifications and variations, be apparent according to above-mentioned content.Therefore, all are such substitute, improve and change all is included in the spirit and scope of attached claim.
