Abstract
The invention relates to a decorated lamp formed by light-emitting diode and relative decorated lamp sequence. Wherein, two ends of light-emitting diode are connected to the load, therefore, the decorated lamp is used as non-pole lamp to alternative power resource to keep semi-wave lighting in one period. With said invention, the light-emitting diode serried on one wire can avoid considering poles, when even the light-emitting diode is destroyed, the load still attain current, therefore, other light-emitting diodes can keep lighting. The inventive lamp sequence has subdivided resistance, to support voltage or current instant impact.
Description
Technical field
The present invention relates to a kind of lighting technical field, especially a kind of lamp and lamp string.
Background technology
Existing incandescent lamp, its luminous brightness is limited, and employed voltage is also lower, generally at a few volt alternating voltages.Its structure is to be provided with tungsten filament in the glass envelope, and the incandescent lamp power consumption is bigger, and tungsten filament is easy to blow, and particularly is in the switch on and off state at voltage, and when perhaps lamp was in continuous blink states, the easier lamp that makes burnt out.When lamp was connected in series composition lamp string, as long as one of them lamp or a plurality of lamp are burnt out, the circuit of this lamp string just can produce temperature rise, and bulb can be brighter, and the electric wire heating produces the potential collision hazard that electric wire cocks off.Because light-emitting diode has low-voltage driving, power saving, be difficult for characteristics such as fragmentation, as the light fixture of light source antidetonation is arranged with light-emitting diode, power consumption is few, do not generate heat and advantage such as environmental protection, now have and replace incandescent lamp with light-emitting diode, light-emitting diode has unidirectional guidance quality, when the positive half cycle of alternating current is added on the both positive and negative polarity of light-emitting diode, the light-emitting diode electrified light emitting, when the negative half period of alternating current is added on the both positive and negative polarity of light-emitting diode, light-emitting diode is by extinguishing, remaining half-wave in the one-period voltage in AC power lights, the frequency of general alternating current is 50HZ～60HZ, like this, the time that light-emitting diode extinguishes at every turn has only 0.01 second, and the pleasing to the eye light-emitting diode of it seems is a light yellow always.But the unilateral conduction of light-emitting diode makes it that light-emitting diode of whole string is serially connected on the electric wire of power supply in the same way, and the whole piece electric wire could form a path, and light-emitting diode could be luminous.If a reversal connection or damage are arranged, then whole lamp string can be not shinny.And because the electric wire of lamp string is the structure of combination of interweaving, when making or safeguarding, when lamp is connected on one when being divided on the end to end plurality of sections electric wire, because between the two neighboring sections electric wire is weave in, at this moment, be difficult to know which end is first, which end is a tail, light-emitting diode correctly will be serially connected on the electric wire, have only the electric wire with weave in to separate, finding out head and the tail can correctly be connected in series.This not only influences the pilotaxitic texture of electric wire, and workload is big, inconvenient operation.
Summary of the invention
The object of the present invention is to provide a kind of life-span long, when connecting alternating current, need not consider the directivity of power supply,, the lamp of the use light-emitting diode that electric current passes through is arranged all no matter at the positive half cycle or the negative half period of power supply.
Another object of the present invention is to provide a kind of long service life, when connecting alternating current, need not consider the direction consistency of each lamp, no matter at the positive half cycle or the negative half period of alternating current, each lamp all has electric current to pass through, and assembles, safeguards the easy lamp string of being made up of light-emitting diode.
