Abstract
The utility model discloses an LED lamp string, comprising a plurality of LED lamps in series. The lamp string is characterized in that: each LED lamp is in parallel connection with a current guide resistor or a voltage regulator tube capable of turning on the whole circuit when the LED lamp is in an open circuit; when certain LED lamp has open circuit phenomenon in the use process of the lamp string, the resistor or a voltage regulator tube conducts current, which can keep the conduction of the whole circuit and ensure the normal use of the other LED lamps, thus the phenomenon that the burnout of one LED lamp causes the whole lamp string to be out of work cannot take place; moreover, as each LED is connected with the resistor or a voltage regulator tube in parallel, when the voltage applied at two ends of the lamp string fluctuates, the resistor or a voltage regulator tube can play a role in stabilizing voltage and buffering, so as to prolong the life-span of the LED.
Description
Technical field
The utility model relates to a kind of lamp string, and is particularly a kind of with the lamp string of LED as light source.
Background technology
Since light emitting diode (being the LED lamp) since have the life-span long, volume is little, caloric value is few, power consumption is low, reaction speed is fast, radiationless and monochromaticjty emitting characteristics and advantage, therefore light emitting diode has been widely used in the various fields, particularly it just progressively is used for replacing fluorescent lamp or common bulb to use as lighting source as a kind of energy-conserving product.Be connected in after in use normally several LED being together in series on the power supply of 110～220V and use, certainly will just have a problem like this: when open circuit takes place a certain LED lamp in this LED lamp string, the phenomenon that whole lamp string does not all work then can occur.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of LED lamp string, and this lamp string can still can keep entire circuit when the open circuit phenomenon takes place a certain LED lamp conducting can normally be used other LED lamp.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of LED lamp string comprises some the LED lamps that are cascaded, and it is characterized in that being parallel with on each LED lamp the water conservancy diversion resistance or the voltage-stabiliser tube that can make the entire circuit conducting when this LED lamp open circuit.
The beneficial effects of the utility model are: the utility model adopts said structure, in use resistance or voltage-stabiliser tube conducting electric current when the open circuit phenomenon takes place a certain LED lamp in the lamp string, thereby the conducting that can keep entire circuit, other LED lamp can normally be used, thereby can not occur burning out the phenomenon that causes whole lamp string not work because of a LED lamp; And owing to be parallel with resistance or voltage-stabiliser tube on every LEDs, resistance or voltage-stabiliser tube can play the effect of voltage stabilizing, buffering when being added in the voltage pulsation at lamp string two ends, thereby can prolong the service life of LED.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the schematic diagram of first kind of embodiment of the utility model;
Fig. 2 is the schematic diagram of second kind of embodiment of the utility model.
The specific embodiment
With reference to Fig. 1, Fig. 2, the disclosed a kind of LED lamp string of the utility model, comprise some the LED lamps that are cascaded, when being parallel with on each LED lamp, can make the water conservancy diversion resistance R or the voltage-stabiliser tube D of entire circuit conducting when this LED lamp open circuit, in use resistance or voltage-stabiliser tube conducting electric current when the open circuit phenomenon takes place a certain LED lamp in the lamp string, thereby the conducting that can keep entire circuit, other LED lamp can normally be used, thereby can not occur burning out the phenomenon that causes whole lamp string not work because of a LED lamp; And owing to be parallel with resistance or voltage-stabiliser tube on every LEDs, resistance or voltage-stabiliser tube can play the effect of voltage stabilizing, buffering when being added in the voltage pulsation at lamp string two ends, thereby can prolong the service life of LED.
The above only is a preferred embodiment of the present utility model; can not limit protection domain of the present utility model with it; the utility model also can have other structural change; as adopt be connected in after the some LED series connection through in the low-voltage circuit of 110～220V step-down or the power supply of other low-tension supplies with as other purposes, also should be in protection domain of the present utility model.
Claims (1)
1. a LED lamp string comprises some the LED lamps that are cascaded, and it is characterized in that being parallel with on each LED lamp the water conservancy diversion resistance or the voltage-stabiliser tube that can make the entire circuit conducting when this LED lamp open circuit.
