[0033] As shown in Figure 1 The utility model provides a novel sound light control energy -conserving device, including control unit, photosensitive unit, sound detection unit, time delay unit and switch unit, photosensitive unit, sound detection unit, time delay unit and switch unit all are connected with control unit, still include human body detection unit with control unit connection.

[0034] As shown in Figure 2 The utility model provides a novel sound light control energy -conserving device's circuit diagram. Among them, the switch unit includes relay J1, the coil positive connection terminal of relay J1 is connected with power supply V CC , the coil negative connection terminal of relay J1 is connected with switch tube and then ground, the control end of switch tube is connected with control unit. The switch tube adopts triode T1.

[0035] The normally open contact of relay J1 is used for being connected in series with the lighting lamp on the commercial power, it can be understood that when the coil of relay J1 is electrified, the normally open contact of relay J1 is closed, at this time, the lighting lamp is electrified and emits light.

[0036] Specifically, the control unit includes a first NAND gate N1C and a second NAND gate N1B. The output end of the light sensing unit, the output end of the sound detection unit and the output end of the human body detection unit are connected to the first input end of the first NAND gate N1C. The output end of the first NAND gate N1C is connected to the control end of the switch tube. The output end of the second NAND gate N1B is connected to the second input end of the first NAND gate N1C.

[0037] The delay unit is connected to the first input end and the second input end of the second NAND gate N1B. The delay unit includes a delay circuit composed of a second capacitor C2 and a fifth resistor R5. The second capacitor C2 and the fifth resistor R5 are connected in series, and the fifth resistor R5 is grounded. The second capacitor C2 is connected to the output end of the first NAND gate N1C. The first input end and the second input end of the second NAND gate N1B are both connected to the fifth resistor R5.

[0038] Specifically, the human body detection unit includes an infrared sensor X1, and the model of the infrared sensor X1 is LHI778. When no one appears, the infrared sensor X1 outputs a high level, the 8th pin of N1C is high, and at the same time, the 9th pin of N1C is high. Therefore, the 10th pin of the output end of N1C is low, the transistor T1 is cut off, the relay does not act, and the infrared control condition is not met. The electronic switch is in the off state, and the lamp is not lit.

[0039] Further, the light sensing unit includes a third NAND gate N1D, a light-dependent resistor R9 and an eighth resistor R8 connected in series. The first input end and the second input end of the third NAND gate N1D are connected between the light-dependent resistor R9 and the eighth resistor R8. The output end of the third NAND gate N1D is connected to the first input end of the first NAND gate N1C.

[0040] In order to make the switch off when the environmental conditions are sufficient light and brightness, a light control circuit is composed of a light-dependent resistor R8 and a fixed resistor R9. When the light brightness is sufficient, the resistance of the light-dependent resistor R8 is very small, the 12th pin and the 13th pin of N1D are low, and the output 11th pin is high. Therefore, the 8th pin of N1C is high, and the 9th pin of N1C is also high according to the table. Therefore, the 10th pin of the output end of N1C is low, the transistor T1 is cut off, the relay J1 does not have a light control condition and does not act, the relay J1 is in the off state, and the lamp is not lit. Figure 2

[0041] Further, the sound detection unit includes a microphone BM and a fourth NAND gate N1A. The output end of the microphone BM is connected to the first input end and the second input end of the fourth NAND gate N1A. The output end of the fourth NAND gate N1A is connected to the first input end of the first NAND gate N1C. The model of the microphone BM is 5442DB.​

[0042] In order to ensure that the sound-light control energy-saving device is only turned on when the environment is dark enough and there is a person, and to avoid misoperation when cats and dogs pass by, a pickup circuit is formed by the microphone BM and other elements. When the environment is dark enough and there is a person, N1D outputs a low level, and the infrared sensor X1 outputs a low level. At this time, if the pickup circuit detects a sound signal, the 8th pin of N1C is at a low level, the 10th pin of N1C outputs a high level, the transistor T1 is turned on, the relay J1 works, the normally open contact is closed, a path is formed, and the lamp is lit.

[0043] In the case that the light brightness is enough or there is no person, even if the microphone BM detects a sound signal, since the 8th pin of N1C is at a high level, the 10th pin of N1C is always at a low level, the transistor T1 is cut off, the relay J1 does not work, and is in an open state, and the lamp is not lit.

[0044] In summary, the novel sound-light control energy-saving device provided by the utility model increases a human body detection unit on the basis of the existing sound-light control circuit, avoids misoperation caused by various external sound signals when there is no person, and achieves that the sound-light control energy-saving device does not work when the light is bright, there is no person, and there is no sound, and ensures that the sound controls the lighting lamp to emit light only when the light is dark and a person needs illumination, so that the sound-light control energy-saving device is more convenient, practical and energy-saving.

[0045] Meanwhile, in order to better meet the needs of users, a relay is selected at the output end of the circuit, so that the types of lamps controlled by the switch are increased, the switch can not only control incandescent lamps, but also control energy-saving lamps, LDE lamps and other lighting lamps, and users have more selection space.

[0046] The novel sound-light control energy-saving device is not directly connected in series with the lighting lamp, isolation is realized between the sound-light control energy-saving device and the lamp bulb through the relay, the weak current of the sound-light control energy-saving device is prevented from flowing through the lighting lamp, and the selection range of the type of the lighting lamp is wider.

[0047] Finally, it should be noted that: the technical features of the technical scheme of the application can be combined arbitrarily, in order to make the description simple, all possible combinations of the technical features in the above embodiments are not described, however, as long as the combination of the technical features does not exist contradictory, it should be considered that it is within the scope of the application.

[0048] The above embodiments are only used to illustrate the technical solutions of the present application, and are not intended to limit the present application; although the present application has been described in detail with reference to the above embodiments, those skilled in the art should understand that the technical solutions recorded in the above embodiments can still be modified, or some or all of the technical features can be replaced by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application, and they should be covered in the scope of the claims and the description of the present application.
