Specific use process is as follows：
When dismantling lamp stand 3, lamp stand 3 is pushed up, so that the dovetail groove 7 on lamp stand 3 can completely disengage trapezoidal rails
6, to which lamp stand 3 be disassembled from storing bucket body 1.
When installing lamp stand 3, as needed by 2 left side of opening alignment visual windows or right side of dovetail groove 7 on lamp stand 3
Trapezoidal rails 6 on, and dovetail groove 7 is slid into trapezoidal rails 6 so that lamp stand 3 can be connected together with trapezoidal rails 6,
Then lamp stand 3 is continued to push down on, until the lower end of lamp stand 3 is connected on baffles 8, just completes the installation of lamp stand 3.At this time
The lamp bar 5 on inclined-plane 4 and inclined-plane 4 on lamp stand 3 is all towards visual windows 2.
After installation is complete for lamp stand 3, if the ambient light around storing bucket body 1 is weaker, then photo resistance Rg will be because
It can't detect sufficiently strong light and resistance value made to increase, the tie point voltage between resistance R10 can also increase, to export
High level signal makes triode Q1 be connected to the base stage of triode Q1, and then the tie point output of triode Q1 and resistance R11 is low
Level makes triode Q2 be also switched on, and then makes the light detection signal of the tie point output high level of triode Q2 and resistance R12
To the base stage of triode Q3, triode Q3 is made to be connected, the coil of relay KA obtains electric actuation, and corresponding normally opened contact KA-1 is closed
It closes.If pyroelectric sensor N1 of the someone on lamp stand 3, lamp stand 3 is able to detect that human infrared radiation at this time, to defeated
Going out the human testing signal of high level to the base stage of triode Q4, triode Q4 is made to be connected, the coil of relay K obtains electric actuation,
Its corresponding normally opened contact K-1 is closed, and the current supply circuit of lamp bar 5 is connected, so that lamp bar 5 is shone, to shine visual windows 2
It is bright.If human body can't detect human infrared radiation far from lamp stand 3, pyroelectric sensor N1, to export low level people
Physical examination surveys signal to the base stage of triode Q4, and triode Q4 is made to end, and the coil losing electricity of relay K resets, corresponding normally opened
Contact K-1 is disconnected, and to cut off the current supply circuit of lamp bar 5, lamp bar 5 is made to be stopped.
Conversely, when if light around storing bucket body 1 becomes strong, then the resistance value of photo resistance Rg will be with ambient
Variation and reduce, the tie point voltage between resistance R10 also reduces therewith, to export low level signal to triode
The base stage of Q1 makes triode Q1 be in cut-off state, and then the tie point of triode Q1 and resistance R11 exports high level, makes three
Pole pipe Q2 is also switched off, and then so that the tie point of triode Q2 and resistance R12 is exported low level light and detected signal to triode
The base stage of Q3 makes triode Q3 end, and the coil losing electricity of relay KA resets, and corresponding normally opened contact KA-1 is disconnected, to cut
The current supply circuit of disconnected lamp bar 5, makes lamp bar 5 be stopped, to save electric energy.
