Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is further described.Following examples are only for the technical solution of the utility model is more clearly described, and can not limit protection range of the present utility model with this.
As shown in Figure 1 and Figure 2, the utility model is a kind of microwave induced LED light distribution box, for panel for electricity distribution box provides illumination, comprise distribution box 1, also comprise LED lamp 2 and microwave induced module 3, distribution box 1 is provided with LED lamp 2, microwave induced module 3 is connected in series with LED lamp 2, microwave induced module 3 is connected with feed cable, in microwave induced module 3, be provided with sending and receiving apparatus and LED lamp drive circuit 4, microwave induced module 3 is by LED lamp 2 drive circuit control LED lamp 2 switches, thus 2 opening and closing of control LED lamp.
Operational amplifier (being called for short " amplifier ") is to have the very circuit unit of high-amplification-factor.In side circuit, conventionally jointly form certain functional module in conjunction with feedback network.Owing to being applied in early days in simulation computer, in order to realize mathematical operation, therefore gain the name " operational amplifier ".Amplifier is the circuit unit of a name of the angle from function, can be realized by discrete device, also can realize in the middle of semiconductor chip.Along with the development of semiconductor technology, most amplifier is to exist with the form of single-chip.Amplifier of a great variety, is widely used in the middle of electron trade.
Wherein, in sending and receiving apparatus, be provided with antenna 5, microwave oscillator 6, differential amplifier 7 and voltage comparator 8, antenna 5 is connected with microwave oscillator 6, antenna 5 is connected with differential amplifier 7, differential amplifier 7 is connected with voltage comparator 8, series winding uses, and voltage comparator 8 is connected with LED lamp drive circuit 4.LED lamp 2 is provided with several, and several LED lamps 2 are connected in series.
Microwave oscillator 6 can be launched Wireless microwave by antenna 5, also can receive by antenna 5 reflected signal of this wireless signal, after amplifying, the differential amplifier 7 that these two kinds of signals form via operational amplifier can detect the variation of phase difference, and the voltage comparator 8 being formed by operational amplifier through next stage and the threshold value of setting relatively after, produce a switching drive signal, driving LED lamp 2 switches.
Transmit and inverse signal input difference amplifier simultaneously, output can obtain an output valve, and in the time that phase difference is a stationary value, output valve is also stable, only needs to continue circulation.In the time that phase difference is not a stationary value, output valve can fluctuate, and relatively, in the time that fluctuating range exceedes threshold value, microwave induced module 3 is exported a control voltage and turned on LED lamp 2 for fluctuation signal and a fixed voltage (threshold value).
Microwave induced module 3 obtains power supply from distribution box 1 input power cable, at ordinary times in low power consumption standby state; In the time having people movable near distribution box 1, microwave induced module 3 lightening LED lamps 2 illuminate distribution box 1 panel and postpone a period of time; If continue to have people's activity, LED lamp 2 just continues to light; When microwave induced module 3 has no longer detected people's activity, or activity is while leaving effective detection range, after 2 time of delays of LED lamp are full, closes, and microwave induced module 3 enters low power consumption standby state again.
Because signal is launched as radio, detection angle can reach 180 degree, and application circuit is extremely simple, with low cost, and reliability is high.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection range of the present utility model.
