Description
Technical field
The utility model relates to the illumination of LED fluorescent tube, is specifically related to a kind of LED fluorescent tube in conjunction with human body infrared induction intelligent dimming.
Background technology
At present, use the LED fluorescent tube of DC voltage on the market, the overwhelming majority adopts switch control, needs artificial opening and closing, can not satisfy the control of modern science and technology social intelligence and replace manually operated needs; And there are problems such as investigative range is little, detectivity is low, poor anti jamming capability to a great extent in the fluorescent tube of employing human body sensing light modulator, causes the very big inconvenience in the use on the one hand, causes the waste of resource on the other hand.
The utility model content
At the problem that above-mentioned prior art exists, the purpose of this utility model is, the LED that a kind of investigative range is wide, detectivity is high, antijamming capability is strong is provided fluorescent tube.
To achieve these goals, the technical solution of the utility model is: a kind of LED fluorescent tube, the input power supply, inductor and the lamp source that comprise electrical connection, inductor is located between input power supply and the lamp source, be used to regulate the brightness in lamp source, described inductor comprises the environment light adjusting circuit that is used to survey human-induced signal's human body sensing end and is used to control the brightness of lamp source, the opening and closing of fluorescent tube can be regulated according to the light luminance of environment, the brightness of fluorescent tube can also be regulated according to the human body information that detects.
Further, described inductor comprises an input and two outputs, and the positive pole of described input power supply is connected with the input of inductor, and the negative pole of input power supply is connected with second output of inductor and the negative pole in lamp source; First output of described inductor is connected with the positive pole in lamp source.
Further, described human body sensing end is surveyed the human body sensing end of infra-red radiation for adopting pyroelectricity material, can detect the fine infrared energy that human body sends.
Further, the human body sensing end is responded to the human body sensing end of human body infrared induction signal for adopting two sensitive first complementary technologies, suppresses the interference of interference, vibration or the light of variations in temperature generation, has improved the job stability of inductor.
Further, described environment light adjusting circuit also comprises the environment measuring circuit that is used to detect surrounding environment brightness, makes the inductor intellectuality.
Compared with prior art, the utility model has improved the function of inductor part, adopt the pyroelectricity material temperature variant property detection infra-red radiation that polarizes, adopt two sensitive first complementarity methods to suppress the interference that variations in temperature produces, improved the job stability of fluorescent tube, can increase its investigative range, solve problems such as speed of detection sensitivity is low, poor anti jamming capability.
Description of drawings
Fig. 1 is the utility model structure principle chart;
Fig. 2 is the utility model sensor structure figure.
The specific embodiment
Below in conjunction with accompanying drawing the utility model being done a step describes in detail:
As shown in Figure 1 and Figure 2, a kind of LED fluorescent tube of the present utility model, include input power supply 1, inductor 2 and lamp source 3, the voltage of input power supply 1 input inductor 2 is DC24V, wherein, inductor 2 comprises an input and two outputs, and the positive pole of input power supply 1 is connected with the input 23 of inductor 2, and the negative pole of input power supply 1 is connected with second output 25 of inductor and the negative pole in lamp source 3; First output 24 of inductor 2 is connected with the positive pole in lamp source 3.
Light is relatively more sufficient during daytime, and the environment measuring electric circuit inspection that the environment light adjusting circuit is 22 li is bigger to surrounding environment brightness, and inductor will connect by disconnecting circuit, and lamp source 3 is closed; When the curtain of night arrived, the environmental monitoring circuit monitoring was low to surrounding environment brightness, and lamp source 3 just can be opened automatically.But evening the no one occasion under lamp source 3 open always and will cause the wasting of resources, at this moment, human body sensing end 21 is started working, it is electrically connected with environment light adjusting circuit 22, the brightness in control lamp source 3, sense the infrared energy that human body sends when human body sensing end 21, promptly detect surrounding environment have the people the time, control lamp source 3 keeps the operate as normal brightness; When human body sensing end 21 sense the surrounding environment no one the time, be not to close lamp source 3 but control lamp source 3 keeps than low-light level, like this, saved the energy under to the demand of illumination and the convenient prerequisite of using satisfying people.
