Abstract
The utility model discloses an infrared induction LED energy saving lamp circuit. The input end of the circuit is connected with a DC power supply, the circuit comprises a transistor switch, and an infrared induction device, an LED lamp and a second photoresistor forming a loop, as well as a diode, a relay, a first photoresistor and the normally open contact of the relay which are respectively connected with the input end of the circuit. The infrared induction LED energy saving lamp circuit is provided with the infrared induction device, so that the lamp is lightened when a person passes by at night, thereby the phenomenon that the lamp is not lighted since a light controlled and sound controlled circuit detects no sound signal is avoided.
Description
Technical field
The utility model relates to a kind of LED energy-saving lamp circuit of infrared induction.
Technical background
The LED light fixture has characteristics such as energy-saving and environmental protection, low-power consumption, has therefore obtained wideling popularize in the application of electronic technology industry.At present, control LED electricity-saving lamp switch except general control mode commonly used, state-of-the-art be " sonic-opticalcon trolled switch ", as patent No. ZL 201020292471.1 " a kind of acousto-optic control electricity-saving lamp based on the emitter follower shutoff "; Patent No. ZL 201020288539.9 " a kind of acousto-optic control electricity-saving lamp based on DC power supply " adopts " sonic-opticalcon trolled switch ".But,, when not starting, just do not reached illumination purposes to audio-switch and sound is faint if having the people to pass by near the LED electricity-saving lamp.Therefore, the application's applicant is devoted to existing light-operated sound control circuit is partly strengthened and improved.
Summary of the invention
The purpose of this utility model is to provide a kind of LED energy-saving lamp circuit of infrared induction, it simple in structure, thus can effectively solve because light-operated sound control circuit detects the phenomenon that causes the LED lamp not work less than voice signal, strengthened practicality.
The technical scheme that realizes above-mentioned purpose is: a kind of LED energy-saving lamp circuit of infrared induction, the input of this circuit is connected to a direct current power supply, it comprises a transistor switch, constitutes an infrared induction device, a LED lamp and one second photo resistance in loop, and the normally opened contact of the diode, a relay, one first photo resistance and the described relay that are connected respectively with the input of described circuit, wherein
The grounded emitter of described transistor switch, base stage connect the normally opened contact and the infrared induction device of described first photo resistance, relay respectively, and collector electrode connects the positive pole of described relay and described diode respectively;
The end ground connection that described second photo resistance is connected with described infrared induction device.
The LED energy-saving lamp circuit of above-mentioned infrared induction, wherein, the adjustable distance of reaction of described infrared induction device is six meters.
The beneficial effects of the utility model are: the utility model is provided with the infrared induction device, it is out-of-date to walk as the people, infrared induction makes lamp bright, though avoided light deepening in the light-operated sound control circuit to detect less than voice signal or sound the phenomenon that lamp does not just work when more weak.
Description of drawings
Fig. 1 is the circuit diagram of the LED energy-saving lamp circuit of infrared induction of the present utility model.
Embodiment
Below in conjunction with accompanying drawing specific embodiment of the utility model is elaborated.
See also Fig. 1, there is shown the LED energy-saving lamp circuit of a kind of infrared induction of the present utility model, the input of this circuit 1 connects DC power supply 2, circuit 1 comprises transistor switch VT6, constitutes infrared induction device 11, LED lamp L and the second photo resistance R2 in loop, and the normally opened contact S of the diode D, relay J, the first photo resistance R1 and the relay that are connected respectively with the input of circuit 1, wherein
The grounded emitter of transistor switch VT6, base stage connect the normally opened contact S and the infrared induction device 11 of the first photo resistance R1, relay respectively, and collector electrode connects the positive pole of relay J and diode D respectively; The end ground connection that the second photo resistance R2 is connected with infrared induction device 11; The adjustable distance of reaction of infrared induction device 11 is six meters.
The termination that LED lamp L and infrared induction device 11 join has a light-operated sound control circuit 3.
The operation principle of the LED energy-saving lamp circuit of infrared induction of the present utility model is as follows:
Within six meters of people's distance L ED lamp L, in a single day the sound control signal that the people was sent when it was dark is detected by light-operated sound control circuit 3, and then LED lamp L will light up as people's illumination of passing by automatically.If this moment, sound control signal was not detected by light-operated sound control circuit 3 because of faint or other reasons, because sensed then infrared ray sensor 11 output high level of people, oxide-semiconductor control transistors switch VT6 saturation conduction, thereby make relay J get, the normally opened contact S closure of relay makes LED lamp L light.
Above embodiment is only for the usefulness that the utility model is described, but not to restriction of the present utility model, person skilled in the relevant technique, under the situation that does not break away from spirit and scope of the present utility model, can also make various conversion or modification, therefore all technical schemes that are equal to also should belong to category of the present utility model, should be limited by each claim.
