The specific embodiment

To combine accompanying drawing and specific embodiment to specify the utility model below, be used for explaining the utility model in the illustrative examples and the explanation of this utility model, but not as the qualification to the utility model.

Embodiment:

Like Fig. 1, Fig. 2 and shown in Figure 3; The described lighting circuit of the utility model system; Comprise distribution box 1, electric wire 2 and light fixture 3; Said distribution box 1 is connected through said electric wire 2 with said light fixture 3, in the said distribution box 1 Switching Power Supply 11 is installed, and is provided with single-pole double-throw switch (SPDT) 111 in the said Switching Power Supply 11.

Because existing LED lamp comprises transformation module, constant flow module and lamp source; This kind is for the common LED developed at first etc.; Said LED lamp only also comprises the LED that goes out with crossing current module and the two-part development of novel in lamp source etc.; The lighting circuit that then adopts also is different, has below done relevant specifying:

First kind of situation: the light fixture 3 that adopts as the user is the Novel LED light that does not have the transformation module; Then need said single-pole double-throw switch (SPDT) 111 is swung to an end; Connect the transformation pattern of said Switching Power Supply 11; The voltage that institute's Switching Power Supply 11 will insert the civil power of said distribution box 1 is transformed between 12V ~ 48V by 110V or 220V, after then said single-pole double-throw switch (SPDT) 111 is connected, and the then said novel LED lamp unlatching that does not have the transformation module.
