[specific embodiment]

As shown in the figure, a kind of lamp string with protection and detachable LED light source device includes power line 1 and a plurality of LED lamp string 2, and LED lamp string 2 is connected in parallel on the power line 1, it is characterized in that being parallel with Zener diode 4 separately on the LED bulb 3 in the described LED lamp string 2.

In the utility model, the Zener diode 5 of LED bulb 3 parallel connections can play a part dual in circuit: at first, when power line 1 is connected on the AC power, because the spread of voltage that AC power provides, make voltage on the circuit, electric current does not stop to change, the voltage that is connected LED bulb 3 two ends on the power line 1 is also along with fluctuation, cause LED bulb 3 to damage because of overtension is breakdown, behind the LED bulb 3 parallel voltage-stabilizing diodes 5, Zener diode 5 can make the voltage on the LED bulb 3 in parallel with it stable, can not fluctuate, LED bulb 3 is worked under rated voltage, prolong the service life of LED bulb 3 because of the instantaneous change of the voltage on the power line 1; Secondly, behind the LED bulb 3 parallel voltage-stabilizing diodes 5, even LED bulb 3 has damaged, the electric current on the power line 1 still can pass through from the Zener diode 5 in parallel with this LED bulb 3, has guaranteed that whole lamp string is still a complete loop, can get final product this moment with having damaged the LED lamp replacing that does not work, when avoiding single use LED bulb 3, power lines 1 just open circuit and to detect replacing very inconvenient in case LED bulb 3 damages, and the user often abandons it, so promptly waste the resources of production, also be unfavorable for environmental protection.
