Emotional lighting device using intelligent sensor {SENSITIVE ILLUMINATING APPARATUS WITH INTELLIGENT SENSOR}

The present invention relates to a lighting device, and in particular, when a person enters or leaves the proximity range by using a microwave Doppler method, the illuminance of the light source is gradually increased according to the distance ratio within the proximity range. The present invention relates to an emotional lighting device using an intelligent sensor that can be easily used for a special purpose and has no inconvenience due to sudden light off, and can save energy.

In general, in various areas in which people are active, such as corridors, aisles, entrances, stairs, bathrooms, exhibition halls, apartments, houses, buildings, and the like, automatic lightings are installed to detect and automatically turn on people.

With regard to such lighting, as the depletion of resources and environmental pollution have become an international problem since the 20th century, energy saving has become the focus of attention in all fields. As the focus shifts from qualitative to qualitative aspects, ways to save energy as well as improve quality are being studied. During this research, energy saving technology due to lighting control system is receiving much attention, and sensor technology such as lighting of lighting system by light sensor, lighting control, lighting of lighting system through residence sensor in each space is increasingly important. And become popular.

Lighting lamps have been applied to various fields and spaces. Although it is applied to stairs, entrances, street lamps, parking lots, and indoor spaces, most of the spaces where sensors are used to save energy include a sensor and a timer to automatically turn on by detecting a person's approach.

As described above, the detection sensor is configured to automatically turn on a light when a person's approach is detected, and includes a light sensor, a heat detection sensor, an infrared detection sensor, a proximity sensor, and the timer.

On the other hand, these lamps have been recently improved to a more advanced form, in addition to a sensor and a timer, including a light sensor has been released. As such, when the illumination sensor is included, a function of automatically lighting and turning off the lamp according to the ambient light is additionally included. That is, the illuminance sensor enables the lighting and turning off by the sensor and the timer when the ambient illuminance is darker than the setting value. When the illuminance sensor is brighter than the setting value, the illuminating sensor cuts off the power applied to the lighting and turns on and off. Make this impossible. This helps to prevent unnecessary loss of power.

However, since the conventional lighting is turned on only for the time set in the timer as described above, the field of view is temporarily blocked due to a sudden turn off, and if the sensor stays at the position even after that, the sensor can be shaken or moved by moving the sensor. There was an inconvenience of having to turn on the lamp again so that it was detected again.

In addition, the biggest problem with a conventional lamp is that the sensor can detect the unnecessary range because it is not limited to a certain range but affects an unnecessary range.

Moreover, since uniform lighting is made only at the maximum illuminance without adjusting the illuminance according to the distance ratio of the person, it causes unnecessary energy waste.

Accordingly, the present invention has been proposed to solve the conventional problems as described above, and an object of the present invention is to automatically enter a person within a close range by a Doppler method for transmitting and receiving waves of a specific frequency band such as microwaves.

1 is a state diagram using the emotional lighting device using an intelligent sensor according to the present invention.

As shown, the present invention determines whether the subject (P) is a person approaching by the Doppler method for transmitting and receiving microwaves by the sensing unit 110 installed with the light source 120 and the illuminance according to the distance ratio It is configured to adjust gradually.

As a result, the emotional lighting apparatus using the intelligent sensor according to the present invention can automatically turn on or off when a person enters or leaves the proximity range, in addition to the distance when the subject P is within the proximity range. By adjusting the illuminance of the light source 120 step by step according to the rain it is possible to prevent inconvenience or waste of energy due to sudden light off. However, in the present embodiment, the description will be mainly made in the case where the subject P is a human, but it is a matter of course that the illumination may be appropriately adjusted even when the subject P is not a human.

Hereinafter, the configuration of the emotional lighting apparatus using the intelligent sensor according to the present invention will be described in detail.

Figure 2 is a configuration diagram for explaining the configuration of the emotional lighting device using an intelligent sensor according to the present invention, Figure 3 is a reference diagram for explaining the illumination control function of the lighting device according to the present invention, Figure 4 is the present invention The flow chart for explaining the operation of the lighting apparatus by.

As shown, the lighting apparatus according to the present invention is the sensing unit 110 for detecting the approaching object (P), the light source 120 for emitting light by the supply of power, and in the sensing unit 110 In accordance with the detected signal is made of a controller 130 for controlling the lighting and turning off, the illumination of the light source 120.

Here, the sensing unit 110 and the controller 130 determine whether the subject P is approaching a person, and perform a key function of adjusting illuminance step by step according to the approaching distance. The explanation is centered.

First, the sensing unit 110, as described above, to detect the approaching object (P), as shown in Figure 2, the transmitter 111 for generating a microwave of a specific frequency band and the transmitter 111 When the microwave generated in the reflected wave from the subject P is reflected, the receiver 112 receives the microwave and determines whether the subject P is a person or an approaching distance based on the wave received from the receiver 112. It is provided with an analyzer 113.

Here, the transmitter 111 basically transmits a signal generator for periodically oscillating the microwave, a frequency amplifier for amplifying the signal generated by the signal generator to an appropriate level, and a signal amplified by the frequency amplifier. And a transmitting antenna unit.

The frequency band of the microwave generated by the transmitter 111 is most preferably 24.05 to 24.25 GHz in the 18.0 GHz to 26.5 Ghz region called K-band of the microwave region. Microwaves in the 24.05 to 24.25 GHz frequency band belonging to a frequency in the K-band region are relatively cost-effective and have high signal processing efficiency because they belong to a long wavelength of about 12 mm.

For microwave, K-band, L-band, S-band, G-band, C-band, J-band, H-band, X-band, M- as shown in Table 1 below. It is classified into various frequency bands belonging to band, P-band, N-band, Ku-band, and R-band.

Radio waves Frequency range
(Ghz) Wavelenghth range
(mm) L-band 1.00-2.60 299.7-115.3 S-band 2.60-3.95 115.3-75.9 G-band 3.95-5.85 75.9-51.2 C-band 4.90-7.05 61.2-42.5 J-band 5.30-8.20 56.5-36.5 H-band 7.05-10.00 42.5-30.0 X-band 8.20-12.40 36.5-24.2 M-band 10.00-15.00 30.0-20.0 P-band 12.40-18.00 24.2-16.7 N-band 15.00-22.00 20.0-13.6 Ku-band 15.30-18.00 19.6-16.7 K-band 18.00-26.50 16.7-11.3 L-band 26.5-40.00 11.3-7.5

However, despite the advantages of the 24.05 to 24.25 GHz band, which is a frequency band of the microwave mainly used in the present invention, when a peripheral device using the same frequency band is disturbed, a problem occurs that the sensing effect is reduced or obsolete. . For example, a frequency band permitted for broadband wireless access service in Korea is 24 to 27 Ghz, which overlaps with 24.05 to 24.25 Ghz in which the present invention is considered as an optimal frequency band. Therefore, if the place where the present invention is installed is the area where the broadband wireless access service is implemented or the device providing the same service is located within the detection range of the present invention, the problem of deterioration of the sensing effect is caused.

In order to overcome such a problem, in the present invention, the transmitter 111 is configured to generate microwaves in other frequency bands together with microwaves in the 24.05 to 24.25 GHz frequency bands belonging to the K-band. That is, in order to simultaneously generate 10Ghz microwaves and 30Ghz microwaves, which are different from 20Ghz microwaves belonging to the 24.05 to 24.25GHz frequency bands, the transmitter 111 can oscillate and transmit microwaves for each frequency band. A signal generator, a frequency amplifier and a transmission antenna are additionally provided.

As such, when the transmitter 111 generates microwaves in various frequency bands, the analyzer 113 maintains a high detection efficiency for the subject P while minimizing the influence of disturbance factors such as rain, vibration, and cellular phones. It becomes possible.

Meanwhile, the analyzer 113, which is a component of the sensing unit 110, determines whether or not the subject P approaching is a person based on the microwaves received from the receiver 112 and whether the approach distance is the same. To this end, the analyzer 113 compares the microwaves generated by the transmitter 111 with the microwaves reflected from the subject P and received by the receiver 112 to transmit a microwave transmittance to the subject P, Know the absorbance and reflectance. When the transmittance, absorption and reflectance of the microwave with respect to the subject P are acquired and understood, it is determined based on this and whether the subject P is a human is determined. Referring to Table 2 below, when the subject P is a human, there is no transmission and some reflection and absorption are performed.

matter Permeation Reflection, absorption metal No penetration Fully reflective water No penetration Completely absorbed Person No penetration Some reflection ice Low penetration Some reflection tree Permeation Microreflection Cellular material Full penetration No reflection

In addition, the distance measurement of the subject P by the analyzer 113 applies a Doppler effect, which is known in general, and detects the density change of the microwave caused by the subject P in the detection area in real time. The approaching distance of (P) can be measured.

The controller 130 is connected to the transmitter 111, the receiver 112, the analyzer 113 of the sensing unit 110, as well as the light source 120, and controls them. As a result, when the subject P is turned out to be a person, it plays a role of controlling the illuminance of the light source 120 to a proper level as well as lighting and turning off.

In order to perform this ultimate role, the controller 130 receives information from the analyzer 113 in real time. Through this, as shown in FIG. 3, when the subject P who enters the relatively far primary proximity range is a person, the light source 120 is immediately turned on with the weakest level of illumination.

Afterwards, the closer the subject P approaches the light source 120 or the set point, the higher the illuminance of the light source 120. When the subject P enters a relatively near-second secondary range, the light source 120 increases. ) To maximize the illuminance.

Subsequently, when the subject P enters the first proximity range out of the second proximity range, the illuminance of the light source 120 is gradually lowered according to the distance ratio as it moves away from the light source 120 or the set point. Thereafter, when the subject P finally goes out of the first proximity range, the light source 120 is turned off.

As described above, the illumination device of the present invention in which the illuminance of the light source 120 is adjusted in real time according to the distance ratio of the subject P, which is found to be a person, has corridors, passages, porches, stairs, In addition to the kitchen and toilet, it can be more useful for special purposes such as exhibition halls, food countertops, study rooms, reading rooms, and stands for learning. In addition, it can be actively used in various lighting spaces, such as bollards, such as low-light lighting around 1m high, such as night lights, such as street lights and security lights.

For example, in the case of the exhibition hall where the exhibits are displayed, if the illuminance of the light source 120 is adjusted according to the distance between the viewer and the exhibit, the exposure time of the exhibit may be greatly reduced since the exposure time may be greatly reduced. It can effectively preserve valuable artifacts such as tributaries and expensive works, and save energy.

The operation of the lighting apparatus according to the present invention configured as described above is well illustrated in FIG. Referring to FIG. 4, when the movement of the subject P is detected in the sensing range region of the sensing unit 110, the analyzer 113 determines whether the person is a person and turns on the light source 120. The analyzer 113 determines how much the distance P is, and adjusts the illuminance of the light source 120 step by step.

Referring to the accompanying drawings, the operation sequence of the emotional lighting apparatus using the intelligent sensor according to the present invention configured as described above is as follows. 5a to 5d is a series of reference diagrams for explaining the operation of the lighting apparatus according to the present invention.

First, FIG. 5A illustrates an initial state in which the subject P does not enter the first proximal range, which is the sensing area of the sensing unit 110. In such an initial state, the sensing unit 110 is always driven to generate microwaves. Light source 120 is in a standby state.

Subsequently, when the subject P enters the first proximal range as shown in FIG. 5B, the microwave generated by the transmitter 111 of the sensing unit 110 collides with the subject P and enters the receiver 112. Is received). At this time, the analyzer 113 determines whether the subject P is a human by grasping the transmittance, absorption and reflectance of the microwave to the subject P and reports it to the controller 130. Then, the controller 130 immediately turns on the light source 120 with the minimum illuminance when the approaching object P is a human.

Subsequently, as the approach distance of the subject P gradually approaches within the first proximity range as shown in FIG. 5C, the controller 130 increases the illuminance of the light source 120 step by step according to the distance ratio. To this end, the analyzer 113 detects in real time the density change of the microwave due to the subject P in the first proximal range, which is a detection area, and measures the approach distance of the subject P, and reports it to the controller 130. The controller 130 adjusts the illuminance of the light source 120 according to the distance ratio.

Subsequently, as shown in FIG. 5D, when the approaching distance of the subject P is closer to enter the secondary proximity range, the controller 130 increases the illuminance of the light source 120 to the maximum. Within the second proximity range, the illuminance of the light source 120 is maintained to the maximum regardless of the approaching distance of the subject P. FIG.

Subsequently, when the subject P enters the first proximity range out of the second proximity range, the illuminance of the light source 120 is gradually lowered according to the distance ratio as it moves away from the light source 120 or the set point. Then, when the subject P finally goes out of the first proximity range, the light source 120 is turned off by the controller 130.

As described above, the lighting apparatus of the present invention may be used for various purposes in various environments, and some examples thereof will be described below. 6 to 8 is a state diagram used in the present invention applied to a variety of ring environment.

First, FIG. 6 is an example in which the lighting apparatus of the present invention is applied to an exhibition hall, a museum, or a kitchen. In this case, the subject (P) is a person, while maintaining the appropriate illumination to guide the subject (P) and at the same time to examine the exhibits (specific items such as kitchen utensils or sinks in the kitchen). Therefore, when the sensing unit 110 detects the subject P, the illuminance of the light source 120 is gradually increased, and when the subject P is viewed close to the exhibit, the illumination unit maintains the illuminance at an appropriate level.

7 is an example in which the lighting apparatus of the present invention is applied to a street lamp or a walking light. In this case, the subject P may be a person or a car. In addition to a wide range of detection by the sensing unit 110, a wider range of irradiation by the light source 120 should be made. At first, when the illuminance of the light source is kept at a low minimum for safety, the subject P approaches. The illuminance of the light source 120 is gradually turned on to a high level.

8 is an example in which the lighting apparatus of the present invention is applied for a learning space such as a reading room. In this case, when the subject P is a human, and the sensing unit 110 detects the approach of the subject P, the illuminance of the light source 120 is gradually increased, and finally, the subject P reads a suitable level. Maintain illuminance.

On the other hand, it is also possible to consider a configuration in which the above embodiment is modified to utilize ultrasonic waves or a magnetic field as the next best alternative to the microwave. In the case of using ultrasonic waves or magnetic fields instead of microwaves, the composition may be similar, but the effects and reliability of accurately determining whether a subject is a person and a movement are considerably reduced because they are affected by the surrounding situation.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. It is clear that the present invention can be suitably modified and applied in the same manner. Therefore, the above description does not limit the scope of the present invention, which is defined by the limitations of the following claims.
