The specific embodiment

About aforementioned and other technology contents, characteristics and effect of the present utility model, in the following detailed description that cooperates with reference to graphic preferred embodiment, can clearly present.

Consult Fig. 1, the utility model can be installed in the preferred embodiment of led lamp 100 of daylight lamp holder, and led lamp 100 mainly is to be used for replacing general fluorescent tube to be installed on the existing daylight lamp holder 300.

Led lamp 100 comprises a LED lamp module 1 and a lamp tube body 2, lamp tube body 2 has a light-transmission tube 21 and two groups of mating parts 221,222, light-transmission tube 21 defines a spatial accommodation 20 jointly with mating part 221,222, and LED lamp module 1 is installed in the spatial accommodation 20.

In this preferred embodiment, each mating part 221,222 has a

crown cap

2210,2220 and two

plugs

2211,2212 and 2221,2222 respectively, in order to be installed on two

installation portions

31,32 of daylight lamp holder 300 respectively.

Consult Fig. 2, LED lamp module 1 has a driver element 101 and a LED lamp string 102, driver element 101 has a mu balanced circuit 11, a feedback circuit 12 and a driving governor 13, mu balanced circuit 11 has a bridge rectifier 111, a booster circuit 112 and a filter circuit 113, and the detailed circuit and the connected mode of itself and feedback circuit 12 and driving governor 13 can be with reference to figure 3.

The interlock circuit and the function mode thereof of LED lamp module 1 are described below:

Bridge rectifier 111 is in order to the alternating current V with the outside _ACCarry out the ac/dc conversion to produce a direct current voltage V _DCBooster circuit 112 is in order to for DC voltage V _DCBoost and produce a relaying voltage V _DC'; Filter circuit 113 is pressed V in order to the centering relay _DC' carry out filtering, an output voltage V that produces after wave circuit 113 filtering after filtration _OutThen supply with LED lamp module 102.

Feedback circuit 12 is current limliting mu balanced circuits, is coupled between mu balanced circuit 11 and the LED lamp string 102, in order to the flow through output voltage V of LED lamp string 102 of reception _OutAnd through producing a feedback voltage V after current limliting and the voltage stabilizing _FB

Driving governor 13 is integrated circuits of a TinySwitch-III series, and model is TNY274-280, couples between mu balanced circuit 11 and the feedback circuit 12, in order to according to feedback voltage V _FBThe corresponding adjustment of comparative result output voltage V with a preset reference voltage _Out, make the output voltage V of the LED lamp string 102 of flowing through whereby _OutKeep constant.
