BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a safety enhancement lighting system in an elevator using LED lighting capable of enhancing passenger safety.

Regulations for lighting fixtures are being made globally in Korea, the US, Europe, Japan, China, and Australia. Since incandescent lamps can not be produced or sold anymore, there is a growing possibility that the market for LED lighting will flow into the market. In Japan, LED lighting market was 40% in 2012. The US and China are also continuing their subsidy policy to expand LED supply.

Various kinds of lighting devices are installed in the elevator car on which passengers ride, in addition to providing a light source inside the closed car and giving a sincere feeling to the passengers. In the elevator car as described above, In recent years, the existing fluorescent lamps have been replaced with environmentally friendly LED lamps as their lifespan is guaranteed.

However, it is a reality that the lighting in the existing elevator occupies most of the fluorescent lamps, and the lighting in the elevator is generally turned off irrespective of the presence or absence of the person after a certain time for the power saving. In other words, an elevator that is not operated is turned off after a certain period of time even if a person exists inside, and sudden change of environment inside, for example, a person who boarded secretly for a crime, , Women can be exposed to crime, or when a person with mental or physical illness faints in the elevator, the light goes out and the emergency situation can not be taken at all. It is very difficult to observe, so responding to these emergencies has a problem of weakness.

Especially, in recent years, various crimes in elevators have become social issues. A sex crime against a child occurred in an elevator in an apartment, and people were greatly shocked by the fact that the safest place to live was the place of crime. Elevators are a necessity for high-rise buildings including apartments. However, when the elevator is running, it becomes a closed room without a refuge, so it is placed in a defenseless state against various crimes. In particular, sex offenders prefer a closed space as a crime place, and one of the spaces meeting these conditions was an elevator. Most elevators are equipped with surveillance cameras to prevent and monitor crimes within these elevators. However, it is actually very difficult for a person to continuously monitor an image taken by a surveillance camera in real time.

1 is a block diagram showing the entire configuration of an LED lighting system for elevator safety enhancement according to the present invention (hereinafter referred to as "the present system").

Referring to FIG. 1, the present system includes an LED lighting module 100 including a plurality of LEDs for providing dimming according to a situation in an inner space of an elevator, and basic information on LED control by detecting a human body or illuminance inside the elevator A control module 300 for controlling the emergency lighting by comparing the set time according to the presence or absence of the human body by illuminating the LED when the human body is sensed in conjunction with the sensing signal of the sensor module 200 and the sensor module 200, ). ≪ / RTI > Particularly, in the present system, a plurality of LEDs are used as illumination devices, and a human body inside the elevator is detected to compare the set time with the stay time in the elevator of the user to determine whether or not the situation is an emergency situation. So that the lighting control and the emergency call system can be linked to each other efficiently.

The LED lighting module 100 allows a plurality of LED elements to be used as illumination. As one embodiment of the illumination arrangement of the LED, for example, a plurality of LEDs may be attached to the inner ceiling plate of the elevator.

In this case, the ceiling plate inside the elevator can be realized with a thermally conductive metal, more preferably a stainless steel material, so that the LED itself can efficiently process heat radiation characteristics. Further, all the walls of the elevator coupled with the ceiling plate may be made of a metal material. In this case, the heat generated in the light emitting operation of the plurality of LEDs forms a wide heat radiation path through the thermally conductive ceiling plate, that is, the thermally conductive metal constituting the wall of the elevator. Accordingly, , Heat generated from the LEDs can easily escape to the outside. In this case, a PCB on which the LED is mounted may be included between the ceiling plate and the LED, but in this case, the PCB may be regarded as a part of several LEDs. The plurality of LEDs, which may be arranged in one embodiment in the present system, are all LEDs emitting white light, and the LEDs can be classified as LEDs in two groups with different color temperatures. In this embodiment, there are two groups of LEDs having different color temperatures, but this does not limit the present invention, but may be a plurality of LED groups. In addition, they represent an LED (referred to as 'WL' hereinafter) which emits warm white color light that gives a warm feeling. (Hereinafter, referred to as 'daylight color LED') emitting light of daylight color giving a relatively cool feeling. Instead of the daylight-colored LED 12b, an LED that emits cool white light of a similar color temperature may be used.

The sensor module 200 may include a circuit board including an object moving in the elevator or various sensors for sensing the presence of a user. Examples of such sensors include an infrared sensor for detecting the heat of a human body, an operation sensor for detecting movement of a person, and an illuminance sensor for sensing the illuminance of the inside of the elevator, And a circuit including a driving circuit or a timer circuit for driving the liquid crystal display device.

The sensor module 200 basically determines whether a person is present in the elevator and sends a detection signal to the control module 300. It is also preferred that the lighting in the elevator is controlled not to be turned off as long as a signal recognizing that a person is present in the elevator is sent to the control module 300. In this case, the elevator is no longer driven If there is no movement of a person for a certain period of time after the stoppage, or if the elevator stops even if a person is loaded, the control module first assumes this as a stage of the emergency situation, classifies the emergency situation, Signal. The sensor module 200 includes a human body sensing part 210 including an infrared sensor for sensing the object, a roughness sensing part 220 sensing the illuminance inside the elevator, a motion sensing part 230 including an operation sensor, As shown in FIG.

When a signal for sensing a user (person) is transmitted from the sensor module 100 to the control module 300, the light control unit 310 sets the illumination so that the illumination is continuously maintained. That is, the dimmer control unit 310 controls the lighting to be continued when a human body is detected to be present in the elevator, and controls the type and intensity of dimming according to human body detection information after a preset time. To this end, the light control agent unit includes a set time comparison unit 311 for setting a set reference time to be a reference according to a number of situations, and performing a counter counting after a human body is detected, A dimming setting unit 312 that adjusts the brightness of the LED when it corresponds to an emergency situation or an offense, and an emergency lighting driver 313 that drives emergency lighting according to a power failure situation or an emergency situation. .

When the sensor module 200 senses the human body, the set time comparison unit 311 performs the counter counting immediately after the illumination is turned on, or the counter counts the time after the elevator stops. In this case, the set time can be set variously according to the user's setting.

For example, when the elevator stops and the crime prevention situation setting time (5 minutes) is counted, in this case, if the sensor module determines that the person is present in the elevator, the emergency situation control unit 320 Automatic calls are made to the central control room and the inside of the elevator is confirmed through the CCTV image. Of course, even in this case, when the person is inside the elevator, the lighting of the elevator is not turned off, so that it can take the necessary measures. Of course, control can be automatically implemented to enhance the illumination of the interior of the elevator to 150% of the normal brightness (dimming setting section 312), which gives a warning to the criminals because the lighting brightness is 150% It is possible to have a sense of stability. In addition, the user can be informed by voice that the recognition of the emergency situation is recorded in advance. If there is no other internal action, a boundary signal, a warning light, a siren, and the like can be added.

The dimming setting unit 312 performs a function of adjusting the brightness of the illumination according to the set conditions as described above. For example, as described above, in the case of an emergency, the brightness of the illumination is set to 150%, thereby giving a warning to the criminals, allowing the passenger to feel more secure, or, in the case of a power failure, The lighting can be implemented to operate. Of course, the setting of the illumination and the setting of the time may be variously modified as described in the embodiment that the user can change.

When it is determined that the user is inside the elevator, the emergency lighting driver 313 activates the illumination through the emergency light if the user is recognized as being inside the elevator. The emergency lighting driver 313 has a function of enabling the countermeasure in case of the time counting for the emergency call .

The control module 300 may further include an emergency situation controller 320 for determining whether or not an emergency situation is present according to the comparison result of the set time in the light management agent section and driving the call and emergency light signals.

The emergency situation control unit 320 includes an emergency state classifying unit 321 for classifying the emergency state into emergency emergency, emergency emergency and crime emergency according to the counting result of the reference time of the set time comparing unit 311, An emergency signal processor 322 for providing an illumination control signal and an emergency call signal suitable for the corresponding situation in accordance with the classification result of the emergency section 321, And an emergency call unit 323 for transmitting an emergency call signal rule to the emergency call unit 321. [

As described above, the emergency situation classifying unit 321 classifies the emergency situations based on a result of inverse counting a preset time in accordance with various situations such as a general emergency situation, an emergency emergency situation, a crime emergency situation, The emergency signal processing unit 322 may transmit a control signal to perform a predetermined operation. For example, in case of an emergency, the emergency call signal should be sent simultaneously to the central office or the emergency room of the registered hospital. Emergency warning lamps shall be sounded at the inside and outside of the elevator to allow the nearest security guard or nearby people to take precautionary measures Can be done. When an emergency switch is depressed in the elevator or a radio emergency signal transmitted by a radio signal is detected, the emergency signal is immediately classified into an emergency situation, and the corresponding signal processing is directly performed through the emergency call unit 323 Can be done.

The emergency signal processor 322 processes the corresponding signal according to the emergency situation classified by the emergency condition classifying unit 321. In case of a crime situation or an emergency situation, the emergency signal processor 322 activates the emergency call unit to transmit an emergency signal rule, The display recording module 330 is operated to enable the user to grasp the inside of the room through the recording and photographing in real time and to operate the dimming setting unit 311 and the emergency lighting driving unit 313 to control the brightness of the lighting, In order to brighten the intensity of illumination with 150% of the normal illuminance, which is known as the most optimal illuminance for crime prevention.

Further, the corresponding configuration is activated so as to notify the elevator of an emergency state through an alarm signal, a siren, and a voice signal. For example, if an emergency patient falls victim to an emergency situation, the patient should be alerted that he / she is aware of the emergency and is handling the emergency. Or, if it is judged as a crime situation, it can be informed of the emergency situation in the elevator and guide the criminal who planned the crime in the elevator to abandon the crime in advance. In order to alert the emergency situation by voice, the emergency situation control unit 320 includes a voice signal processing unit 324 for transmitting an emergency signal corresponding to an emergency situation and a crime situation, And more preferably,

The concept of enhancing the safety through control of illumination in the elevator in the present system may further include the following embodiment in consideration of the special situation of the elevator.

In other words, it should be considered that, in the case of an elevator, crime situations, crime preliminary situations, and emergency situations can be exposed to very dangerous situations even if the user can not cope properly and only in a matter of seconds and minutes .

For this, in the system according to the present invention, when the emergency switch 400 is pressed as shown in FIG. 1, the same process as that of the above-described emergency call signal transmission can be performed.

That is, referring to FIG. 2, this is a flowchart schematically showing the operation state of the present system described above with reference to FIG. 1. Specifically, the control module performs initialization to newly collect elements for controlling illumination, (At the same time, waiting for the victim to hide in the elevator for the purpose of crime), emergency (the patient is fainting, A non-moving seizure, a situation in which the user can not move due to pain, etc.), sends out an emergency call signal, enhances the illumination in the elevator, and performs voice guidance and warning sirens.

This process is a special configuration only for this system linked to the lighting control. However, as described above, in the situation where counting of the set time is difficult even in the special feature in the elevator, emergency call is immediately made in the case of pressing the emergency switch in the elevator. The intensity of the illumination is enhanced and the process of performing the voice guidance and the like can be performed.

However, if the emergency switch can not be depressed in the elevator, and the emergency patient is paralyzed on the floor, the emergency high switch can not be depressed. Even if the criminal is overtaken by the rider, It is more preferable to be connected so that the emergency signal can be transmitted through a separate wireless switch.

For example, as shown in FIG. 3, by embodying a method of sending an emergency signal by using a wireless terminal instead of a method of transmitting an emergency signal by pressing an emergency switch provided in an existing elevator, So that the emergency signal can be transmitted using the wireless terminal even in the absence of the emergency signal. In this case, it is implemented as an emergency signal (second emergency signal) different from the emergency signal (first signal) generated when an existing emergency switch is pressed, so that when an emergency signal is transmitted, it can be immediately recognized as a crime or an emergency And to perform coping. Of course, in this case, it is more preferable that the control module further includes a transmitting element which has a wireless receiving element for receiving the emergency signal and transmits a wired or wireless emergency signal to the outside.

For example, when a user having a wireless terminal capable of driving a call of an emergency signal of the present system is placed in an emergency in an elevator, when an input signal is formed by depressing a switch of the wireless terminal depending on the situation The wireless terminal is provided with an input signal switch for forming at least one or more different radio signals and is provided with an input signal switch for transmitting an emergency signal when the emergency situation (medical condition, emergency switch is not pressed due to an injury situation) It is possible to further comprise a switch which has an input signal switch which can be pressed in a difficult situation, and which forms a release signal for releasing the transmission signal in the case of erroneous depression. In this case, the input signal switch may be a structure provided in a small terminal in the form of a remote control, a form of a transportation card that can be carried in a wallet, a bag or a pocket, or a key ring, It can also be implemented as a structure that can not be used. Regardless of the structure of the input signal, the input signal switch can be implemented as a component capable of generating a pressure-type or touch-type input signal, thereby realizing a single input signal. For example, it is possible to emit a radio frequency signal having a specific pulse, which can be implemented as a driving signal of an emergency signal switch. In this case, the illumination intensity of the LED in the elevator is strongly controlled, .

In addition, a fourth switch for generating a release signal according to a predetermined pattern (for example, recognizing the release signal when the switch is continuously pressed 5 times) when the switch of the wireless terminal of the system is accidentally pressed by mistake .

The switching signal according to the first to fourth switches may be configured to include an input signal forming unit 120 that processes the switching signal into a wireless signal that can be transmitted through the input signal forming unit 120 of the wireless terminal 100 It is possible. In the case of the input signal forming unit 120, the input signal forming unit 120 is processed into a radio signal to be recognized as an urgent signal of a specific subject in cooperation with a unique code storage unit 140 that stores a unique code of an owner possessing the wireless terminal 100 It is also possible. The input signal forming unit 120 includes first to fourth signal forming units 121 to 124 that can receive switching signals from the first to fourth switches and emit radio frequencies with pulses of different emergency signals, ). ≪ / RTI >
