Description

A corridor lighting lamp

technical field

The utility model relates to a lamp, in particular to an illuminating lamp used in corridors, which belongs to the field of lighting. the

Background technique

The current common corridor lights are usually controlled by manual switches, and people must touch the switches when using them. Because it is generally used at night, people have to find the switch in the dark based on their impressions, which is very inconvenient to use. the

In order to solve the problem of finding the switch in the dark, an indicator light is provided on the switch, but the brightness of the indicator light is generally very limited, and people still have to carefully step up the steps to touch the switch. There is a voice-activated switch that is gradually applied to corridor lights, which is controlled by sound, but sometimes the sound is not caused by humans, so the lights are often turned on by mistake, resulting in waste of electric energy. the

Utility model content

The utility model proposes an induction type corridor lighting lamp aiming at the deficiencies in the prior art. the

The lighting lamp includes a lamp, a power conversion circuit, a micro-processing unit, a human body sensor, an amplifying circuit and a control circuit, wherein: the human body sensor is connected to the micro-processing unit through the amplifying circuit, the micro-processing unit is connected to the lamp through the control circuit, and the power conversion circuit is connected to the mains The power supply supplies power to all power consumption units. the

Preferably, the human body sensor adopts a pyroelectric infrared sensor. the

The control circuit includes a drive circuit and a relay circuit. the

Preferably, the light fixture adopts an LED array. the

Technical effect:

1. Simple structure, sensitive sensor, easy to use, can be applied to many night lighting occasions. the

2. It avoids the accidental turning on of the lamp and will not waste electric energy. the

3. There is no need to set a switch, making the corridor lighting more intelligent. the

Fig. 1 is a structural block diagram of the utility model. the

Detailed ways

Below the utility model is described further. the

The structure of the corridor lighting lamp of the present utility model is shown in Figure 1, comprises lamps and lanterns, power conversion circuit, micro processing unit (MCU), human body sensor, amplifying circuit and control circuit, wherein: human body sensor connects micro processing unit through amplifying circuit, micro The processing unit is connected to the lamp through the control circuit, and the power conversion circuit is connected to the mains power supply to supply power to all the power consumption units. the

The micro-processing unit is composed of a single-chip microcomputer and its peripheral circuits. For the single-chip microcomputer, we use TI's low-power MSP430 series single-chip microcomputer; There will be no induction; the amplifying circuit adopts low-noise high-speed operational amplifier LM358, which is used to amplify the weak electrical signal output by the human body sensor, and then sends it to the single-chip microcomputer; the lamps and lanterns use low power consumption, long life, and well-illuminated white light LED array; The control circuit includes an LED drive circuit and a relay circuit, the relay circuit can realize the automatic switch function of the lamp; the power conversion circuit uses a voltage conversion chip and a rectifier device, which is used to convert the mains power into a suitable voltage to supply power to the corresponding unit. the

The utility model can be expanded and applied to many induction switch lighting occasions. On the one hand, it improves intelligence, and on the other hand, it can effectively save electric energy. the
