In the state write memory 1122 of microprocessor 1121 meetings with the 3rd switch 1131 and the 4th switch 1132, when the state of memory 1122 is written as activation (on), represent the 3rd switch 1131 for opening circuit, the 4th switch 1132 is a path; When the state of memory 1122 is written as disabled (off), represent the 3rd switch 1131 to be path, the 4th switch 1132 is for opening circuit.
See also Fig. 8, when led lamp was loaded on daylight lamp holder 140 (or 150), the operational process of this circuit switch unit 110 was as follows:
At first, this microprocessor 1121 reads the state of memory 1122, as step S801, sends the control signal of varying level height then according to the state of memory 1122, as step S803.When if memory 1122 is off, then microprocessor 1121 outputs one low level signal makes the 3rd switch 1131 be path, and the 4th switch 1132 is for opening circuit, second plate port 41 is connected in the 4th plug 80, the second negative electrode ports 42 connections the 3rd plug 70 then.
When if memory 1122 is on, then the signal of microprocessor 1121 outputs one high level makes the 3rd switch 1131 for opening circuit, and the 4th switch 1132 is a path, second plate port 41 is connected in the 3rd plug 70, the second negative electrode ports 42 connections the 4th plug 80 then.
Then, microprocessor 1121 monitorings judge whether signal has generation, as step S805.If in a period of time (for example one minute), this comparator 1113 does not all produce any judgement signal, it is correct then representing the annexation between present second plate port 41, the second negative electrode port 42, the 3rd plug 70 and the 4th plug 80, starter 146 (or 156) no current flows through and starts, and the magnitude of voltage of the first negative electrode port 32 can not change to some extent yet.Microprocessor 1121 will stop monitoring judgement signal then, and as step S807, memory 1122 still remains in existing state.
And if comparator 1113 has the judgement of generation signal, represent the annexation between present second plate port 41, the second negative electrode port 42, the 3rd plug 70 and the 4th plug 80 incorrect, cause starter 146 (or 156) to be activated.Microprocessor 1121 is changed the state of memories 1122 at this moment, as step S809, and then send the control signal of varying level height according to the state of memory 1122, as step S811, changing the state of the 3rd switch 1131 and the 4th switch 1132, and then change annexation between second plate port 41, the second negative electrode port 42, the 3rd plug 70 and the 4th plug 80.Memory 1122 remains in the state after the change afterwards.
Whereby, as long as the starter 146 (or 156) of daylight lamp holder 140 (or 150) is activated, this circuit switch unit 110 can both automatically switch the state of its switch module 113, adjust the annexation between second plate port 41, the second negative electrode port 42, the 3rd plug 70 and the 4th plug 80, allow starter 146 no longer be activated.

When led lamp is loaded on daylight lamp holder 140 (or 150), if the annexation between second plate port 41, the second negative electrode port 42, the 3rd plug 70 and the 4th plug 80 is correct, starter 146 (or 156) no current flows through, and this moment, comparator 1113 can not produce the judgement signal.
If the annexation between second plate port 41, the second negative electrode port 42, the 3rd plug 70 and the 4th plug 80 is incorrect, makes starter 146 (or 156) have electric current to flow through and start.This moment, comparator 1113 sent the judgement signal, allowed the 3rd switch 1131 switch to and opened circuit, and the 4th switch 1132 switches to path.Changed the annexation between second plate port 41, the second negative electrode port 42, the 3rd plug 70 and the 4th plug 80, allowed starter 146 (or 156) no longer include electric current and flow through.When the 3rd switch 1131, the 4th switch 1132 changed state, light emitting diode 11,21 meeting flickers were several down, just can not glimmer afterwards.
