Description

Induction lighting fixtures and induction lighting systems

technical field

The utility model relates to an induction lighting fixture and an induction lighting system using the induction lighting fixture, in particular to an induction lighting fixture and an induction lighting system which can perform linkage management on lighting in multiple areas.

Background technique

With the acceleration of urbanization and the continuous improvement of people's living standards, more and more large-scale public infrastructure and large-scale residential quarters or commercial centers have been built. How to manage the lighting of these large-scale buildings reasonably, effectively and energy-saving , has become an increasingly important issue.

For example, large residential quarters and commercial centers usually have underground parking lots with an area of tens of thousands of square meters and lack of natural light sources. If a traditional lighting solution is used, either each lighting area must be monitored separately, and the light sources in that area must be manually turned on individually when people or vehicles enter or exit; or all light sources in all lighting areas must be kept on. Although the former solution is energy-saving, it is difficult to manage and is prone to mistakes; the latter solution has good lighting effect, but it consumes a lot of energy and is very wasteful, and the long-term lighting of the lamps will also affect its service life.

In order to solve the contradiction between the above two schemes and combine the advantages of the two, in recent years some buildings have adopted induction lighting schemes. For example, in the corridor of a residential building, when someone passes by a certain floor, it makes a sound, and the acoustic signal is received by the acoustic sensor, then the light on that floor is automatically turned on; when the person leaves the floor, the light goes off immediately. Although this method does not require people to manually turn on the lighting, it is very convenient and energy-saving, but because the sensing coverage of the sensors installed on each lamp is small, it cannot be used for lighting in wide areas such as parking lots.

On the other hand, for the entrance and exit of the underground parking lot or narrow and long areas such as tunnels, when the vehicle passes by, only the lighting in the front and rear ranges is lit, and the distance is still dark, which will bring fear to the driver and cause serious problems. There will be lighting blind spots, and it is easy to miss pedestrians or vehicles, causing accidents. Or, in order to reduce lighting costs, although the light sources in the entire area are turned on, their brightness is dimmed, thereby affecting the sight of drivers or pedestrians.

Detailed ways

In the following, the induction lighting lamp 10 and the induction lighting system 60 of the present invention will be further described in conjunction with specific embodiments. It should be understood that the following examples are only used to illustrate the utility model but not to limit the scope of the utility model.

Example 1:

Accompanying drawing 1 is the block diagram of the induction lighting system of embodiment 1.

As shown in FIG. 1 , the induction lighting system 60 is composed of multiple induction lighting lamps 10 sharing the same power source 12 , taking three induction lighting lamps 10 a , 10 b , and 10 c as an example. Each induction lighting fixture 10 includes a power supply control module 30 , an induction control module 20 , a switch module 40 , a linkage terminal 61 , a ground terminal 63 and a light source unit 11 .

Wherein, the power supply 12 is AC220V commercial power. The power supply control module 30 receives electricity from the mains, and converts it into a 12V DC low voltage through an AC/DC conversion circuit 35 , and then supplies power to the induction control module 20 , the switch module 40 and the light source unit 11 .

The induction control module 20 is composed of a DC voltage conversion circuit 27 , an induction circuit 24 and an optical control circuit 26 , and its function is to generate an induction signal by sensing external signals and send the induction signal to the switch module 40 . The DC voltage converting circuit 27 converts the 12V DC delivered from the power supply control module 30 into a 5V DC suitable for the sensing circuit 24 and the light control circuit 26 . The sensing circuit 24 judges whether there is a pedestrian passing through by sensing the external infrared signal, and generates a sensing signal accordingly. The light control circuit 26 senses the external light intensity. If the external light intensity is weak, the induction circuit 24 is allowed to send the generated induction signal to the switch module, otherwise the output terminal of the induction circuit 24 is closed, so that no matter whether the induction circuit 24 senses the Infrared signals do not output induction signals. The simple use of infrared sensing can realize that the lights are turned on only when pedestrians pass by, thereby saving power; while the combination of infrared sensing and light control can automatically stop lighting during the day, further saving energy.

When the switch module 40 receives the induction signal from the induction control module 20, it is turned on, and sends a lighting signal to the light source part 11, so that the light source part 11 is turned on, and when the induction signal is not received, the lighting signal is not sent, and the light source Section 11 goes out.

The linkage terminal 61 is disposed between the switch module 40 and the light source unit 11, and the lighting signal sent from the switch module 40 to the light source unit 11 must pass through the connection point 64 of the linkage terminal 61 to reach the light source unit. The linkage terminals 61 of the induction lighting fixtures 10 in the system are connected to each other, so that as long as the linkage terminal 61 of one induction lighting fixture 10 receives the lighting signal, it will transmit the lighting signal to other linkage terminals 61, thereby The light source parts 11 of all induction lighting fixtures 10 are turned on at the same time; only when the linkage terminals 61 of all induction lighting fixtures 10 fail to receive the lighting signal, the light source parts 11 of all induction lighting fixtures 10 will be turned off simultaneously.

The function of the ground terminal 63 is to ground the switch module 40 , and the ground terminals 63 of the induction lighting fixtures 10 in the system are connected to each other, so that the switch modules 40 of the induction lighting fixtures 10 share a common ground.

The light source unit 11 is a set of LED lamps 13 .

Accompanying drawing 2 is the working flowchart of the induction lighting system 60 of the first embodiment.

As shown in FIG. 2 , after the induction lighting fixture 10a is started, the power supply control module 30 supplies power to the induction control module 20 , the switch module 40 and the light source unit 11 (step 1).

After the power is turned on, judge whether the lighting signal from other linked terminals 61 is received through the linkage terminal 61 (step 2), if the lighting signal is received, then jump to step 7 described later; if the lighting signal is not received, the process ends .

At the same time, it is judged whether the output terminal of the sensing circuit 24 is blocked due to the effect of the light control circuit 26 (step 3), if blocked, the process ends.

If the output terminal of the sensing circuit 24 is not blocked, it is judged whether the sensing circuit 24 has sensed an external signal (step 4).

If the sensing circuit 24 senses an external signal, it will generate a sensing signal and send it to the switch module 40 (step 5).

The switch module 40 receives the sensing signal from the sensing circuit 24, generates a lighting signal, and sends the lighting signal to the light source unit 11 of the sensing lighting fixture 10a. At the same time, the lighting signal is transmitted to the induction lighting fixtures 10b, 10c and the light source parts 11 of all other connected induction lighting fixtures 10 through the linkage terminal 61 of the induction lighting fixture 10a (step 6).

The light source units 11 of all the induction lighting fixtures 10 in the system receive the lighting signal and emit light at the same time (step 7).

After the light source unit 11 starts emitting light, it is judged whether or not the lighting signal is continuously received (step 8). If the lighting signal is continuously received, the light source unit 11 continues to emit light, and returns to step 8; if the lighting signal disappears, the light source unit is turned off (step 9), and the process ends.

Example 2:

Accompanying drawing 3 is the block diagram of the induction lighting system 60 of embodiment 2 of the present utility model.

As shown in FIG. 3 , like Embodiment 1, each induction lighting fixture 10 in Embodiment 2 includes a power supply control module 30 , an induction control module 20 , a switch module 40 , linkage terminals 60 and a light source unit 11 .

And embodiment 2 has the following difference with embodiment 1: the induction circuit in the induction control module 20 has delay circuit 25 and malfunction preventing circuit 28; The centers 62 are connected to each other, so that they can be controlled by the control center 62 uniformly, and the light source units 11 in all the induction lighting fixtures 10 can be manually turned on by the operator.

FIG. 4 is a circuit diagram of an induction lighting fixture 10a in the induction lighting system 60 of the second embodiment.

As shown in FIG. 4 , the power supply control module 30 receives mains power through N and L terminals. The mains power of AC220V enters the rectifier bridge through the N and L terminals, and then is filtered by the large capacitor C2. The resistor R6 provides the turn-on voltage for the power switch chip TNY280, and the TNY280 works. Resistor R7, resistor R8, resistor R', capacitor C4, diode D8, and diode D9 are used to absorb the primary back EMF of the transformer and protect TNY280.

When the power switch chip TNY280 starts to work, the commercial power of the A capacitor C220V will be converted into a constant voltage of about 12V through the AC-DC conversion circuit 35 and sent to the subsequent circuit. The AC-DC conversion circuit 35 is composed of the following components: diode D11, R9, and capacitor C7 provide auxiliary power for TNY280; diode D10, capacitor C6, capacitor C9, and inductor L1 form an output filter circuit; resistor R10, resistor R11, resistor R13, and resistor R14 , resistor R15, capacitor C8, three-terminal parallel Zener diode TL2, and photocoupler U3 form an output feedback network, thereby adjusting the output voltage to a constant 12V.

The induction control module 20 first includes a DC voltage conversion circuit 27 composed of a resistor R14, a transistor Q2, a diode D1, a capacitor C13, and a capacitor C14. After passing through the DC voltage conversion circuit 27, the output voltage of 12V is reduced to 5V and is Input to pin 13 of the control chip CS9803.

The sensing control module 20 also has a sensing circuit 24, which includes an infrared sensor PIR and a control chip CS9803. The infrared sensor PIR in this embodiment is a pyroelectric sensor for sensing external infrared signals. If the infrared radiation (wavelength is about 10 microns) signal released by the human body is received, a microvoltage signal of about 250mV is output from the S terminal to pin 2 of the control chip CS9803. The control chip CS9803 amplifies the micro-voltage signal to generate an induction signal of about 5V, which is output to the switch module.

The control chip CS9803 has a built-in two-stage operational amplifier, which amplifies the microvoltage signal sent by the infrared sensor PIR. However, during the amplification process, due to noise interference, it is easy to malfunction. In particular, the higher the sensitivity of the infrared sensor PIR, the more clutter and the greater the interference. Therefore, a malfunction prevention circuit 28 is provided at the output terminal of the second-stage operational amplifier, and a capacitor C9 is arranged in the malfunction prevention circuit 28, which acts as a filter to filter out interference signals, thereby ensuring the operational amplification of the output Signals are reliable. In addition, the capacitor C9 in the malfunction prevention loop can also be replaced with an inductor or other components, as long as it has a filtering effect.

At the same time, the sensing control module 20 also has a light control circuit 26, one end of the light control circuit 26 receives the same input voltage of 5V as the control chip CS9803, and the other end of the light control circuit 26 is grounded, which is equivalent to parallel connection with the control chip CS9803. Moreover, the light control circuit 26 is also connected to pin 9 of the control chip CS9803 in a constant current manner. A photoresistor RG. is connected in series with the light control circuit 26, and the higher the external brightness is, the smaller the resistance value of the photoresistor is.

If the external brightness is very high and the resistance value of the photosensitive resistor RG is very small, then the voltage of the light control circuit 26 is very small, which is equivalent to ground zero potential, and the control chip CS9803 connected in parallel with it is also equivalent to zero potential, and its pin 11 is blocked. Even if the infrared sensor PIR senses the infrared signal, the control chip CS9803 cannot output the sensing signal. Conversely, if the outside brightness becomes darker, the resistance of the photoresistor RG increases, and the voltage increases accordingly, and the blockade of pin 11 of the control chip CS9803 is released. The control chip CS9803 can generate and Output sensing signal.

In addition, the sensing circuit 24 also has a delay circuit 25 composed of an oscillating circuit. Its function is to make the sensing control module 20 continue to maintain and output the sensing signal within a certain period of time when the infrared sensor PIR has not sensed the infrared signal. Signal. In this way, the LED light 13 is unlikely to be extinguished suddenly when pedestrians just pass by, which is more humane. In addition, by adjusting the resistance value of the variable resistor R5 provided in the delay circuit 25, the delay time can also be adjusted. For example, in the parking lot and other places where vehicles pass, it is enough to set the delay to 30 seconds; while in corridors, halls and other pedestrian places, set the delay to 1 minute, so as to leave sufficient time for pedestrians to stay away from the building .

The switch module 40 in this embodiment is a field effect transistor 2SK2662. When the field effect transistor 2SK2662 receives a 5V induction signal, it turns on, and outputs a low potential from the drain to the LED lamp 13 through the linkage terminal 61, so that the LED lamp 13 is turned on. This low potential functions as a lighting signal. The linkage terminals 61 of all induction lighting fixtures 10 in the induction lighting system 60 are connected to each other, and any linkage terminal 61 among them will transmit the lighting signal to all other linkage terminals after receiving the lighting signal, so that the LEDs in other induction lighting fixtures 10 Lamp 13 is also lit at the same time.

The source of the FET 2SK2662 is grounded, and a ground terminal 63 is provided at the ground end, and the ground terminals 63 of the induction lighting fixtures 10 in the system are also connected to each other. This is because, since the induction lighting system 60 is powered by AC mains, the phases of the input currents of the LED lamps 13 in the system are likely to be different. If the linkage terminals 61 are connected together hastily, it is likely to cause a short circuit due to different phases. Therefore, in this embodiment, the sources of the field effect transistors 2SK2662 are grounded and connected to each other to adjust the phases of the input ends of the LED lamps 13 to be consistent, thereby avoiding short circuits.

In addition, the linkage terminals 61 of all induction lighting fixtures 10 in the system can also be uniformly connected to a control center 62, and then the operator located in the control center 62 directly sends a lighting signal, so that the switch module 40 does not receive the induction signal, but When the operator judges that lighting is needed, all the LED lamps 13 in the system are manually turned on.
