Description

Light emitting diode lighting lamp and light emitting diode lighting device management system employing the same {LED lamp management system}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electrical apparatus installed in an underground parking lot of a multi-unit house such as an apartment, a parking lot of a large building, and a dark building, and more particularly, to a light emitting diode lighting device and a light emitting diode lighting device management system employing the same.

In general, incandescent lamps and fluorescent lamps have been mainly used to brighten dark areas in underground parking lots of apartment houses, apartment buildings, large buildings, and dark buildings.

As is well known, fluorescent lamps are representative luminaires. When a voltage is applied to the fluorescent lamp circuit, the lighting tube is heated by the action of discharge, whereby the bimetal movable electrode is bent to come into contact with the fixed electrode to stop the discharge. At this time, sufficient starting current flows to heat the filament of the fluorescent discharge tube. When the movable electrode is cooled again and falls from the fixed electrode, the high voltage required for discharge is generated in the ballast due to the sudden change of current. At this time, the filament is heated to emit hot electrons and the fluorescent discharge tube is turned on. When light is projected onto the fluorescent material painted on the inner wall of the discharge tube, the fluorescence is generated and changed into a visible light. Such a fluorescent lamp is more efficient than an incandescent lamp and consumes about three times less power. In addition, the light is soft, has the advantage of almost no heat, the life is 5 to 6 times longer than incandescent lamps. On the other hand, the rated voltage of fluorescent lamps is within 6% of the top and bottom. If the voltage is high, the blackening proceeds and the life is short, so it should be replaced frequently. It will not light up when the voltage is low. Fluorescent lamps are shortened for about 1.5 hours by one flash, so they should be used where the number of flashes is small. The characteristics fluctuate depending on the ambient temperature, and it is difficult to light up outside the range of 0 to 40 ° C, and the brightness is lowered. In addition, fluorescent lamps that have reached their end of life are deteriorated in luminous flux due to deterioration of fluorescent material, which is uneconomical and significantly diminishes. And there is a glare of light, and if it breaks, it becomes environmental pollution.

Recently, it has been developed to use a light emitting diode (hereinafter referred to as LED) as a luminaire to replace a fluorescent lamp.

The LED is injected into the junction surface where the P-type semiconductor, which is a hole in which the electric carrier is opposed to the electron, and the N-type semiconductor, in which the carrier is an electron, is injected with a minority carrier so that the electrons are excited at a higher energy level. Then, when the injected electrons and holes are recombined in a stable state again, the excited energy is radiated as an electromagnetic wave having a wavelength band of light to emit light in the visible region or the near infrared region.

In recent years, thanks to the rapid development of semiconductor technology, LEDs have been released from general products with low brightness, enabling production of high brightness and high quality products. In addition, as the implementation of high-performance blue and white diodes becomes a reality, the application value of LEDs is expanding.

Such LEDs have the inherent advantage of very low power consumption due to their high light conversion efficiency. In addition, since it is a small light source, it can be miniaturized, thinned, and lightweight. In addition, mercury, such as fluorescent lamps, because it does not use a discharge gas is an environmentally friendly light source without mercury lamps, has a merit that does not generate garbage because the life is semi-permanent use for at least five years.

Recently, in addition to the green policy to reduce CO2, high brightness LED lamps with relatively long lifespan and low power consumption have been developed recently, but the initial investment cost is high to apply to various interiors of parking lots or buildings, and heat and lighting Since there are some problems in terms of implementation of the control technology, the application is insufficient.

For example, since the LED lamp is different in size, structure, and power supply from the conventional fluorescent lamp, when replacing the LED lamp, the raceway for installing the LED lamp and even the surrounding structure must be completely changed.

In addition, when controlling the illuminance, if there is no person, it controls the illuminance of the LED lighting lamp darkly, and when a person appears, it is a simple control that increases the intensity of light emission and brightens it. It was difficult to adjust the illuminance.

In addition, any LED lamps in case of using LED lamps connected in series may fail to light all the LED lamps connected in series in this fault. Moreover, when removing and replacing any LED lamps and the LED lamps removed There is a problem that all LED lights connected in series are turned off. In addition, it was difficult to monitor remotely unless the status of the faulty LED lamp was checked directly, and it was not easy to centrally manage defect data such as power usage data or lights.

By controlling to respond to the illumination control value, the light emitting amount of the LED lamp unit 42 is maintained at the set basic illuminance value. Allow the default illuminance value to change.

In FIG. 1, the lighting device management server 20 is connected to the parking server 10, which is a ubiquitous parking information system connected to an RFID receiver, in order to provide the location information generation signal. Of course, the vehicle may be connected to an electronic communication system for determining a vehicle parking position connected to the frequency communicator or to a portable wireless terminal that generates an emergency call signal or a radio transmission signal having a unique ID.

Referring to Figure 2 showing the detailed configuration block of the LED lighting control unit 32,

A power supply 320 for converting AC power (eg 220V) supplied through the lines L2 and L4 into DC power (eg DC5V, DC15V, DC220V), and an illumination control signal applied through the line L20 ( In response to the DCS, the LED driver 322 for controlling the driving constant current between the first and second electrodes NO1 and NO2 and the signals connected to the communication lines RS485 + and − are interfaced.

At least one of a contact input unit 328 applied to the 330 and the manual control unit 332 for manually adjusting the LED driver 322 to be dimmed and on / off. It may be further provided.

In the present embodiment, it is assumed that the commercial AC power supply 220V, but 380V or other AC voltage can be drawn. The communication line interface unit 326 may be implemented as "SP485E".

3 to 5, the LED lamp 42a,

A housing 116 connected to the raceway 100 of FIG. 10 in which a lighting power line for transmitting a driving constant current is accommodated, and a DC power is inserted into the accommodation space 424c of the housing 116 and through the lighting power line. The substrate 424b to be applied and the light emitting diode units LED1 and LED2 are arranged in a matrix form on the substrate 424b and receive light while being controlled in a constant current control manner by receiving DC power applied to the substrate 424b. A light emitting diode array 424; A cover 424d that covers the receiving space 424c of the housing and transmits the light emitted from the light emitting diode array 424 to the outside, and is located in the housing or the raceway so as to be located on the substrate 424b or the light emission. When the diode array 424 is removed from the housing 116 or when some of the light emitting diode units LED1 and LED2 do not emit light, DC power applied to the substrate 424b is applied to a rear lamp or the like. It includes a bypass unit 420 for bypassing to the second electrode (NO2).

The cover 424d may be a photocatalytic coated polycarbonate-based plastic panel, and may be manufactured to have a lens function. If necessary, a refractive lens part for screwing light diffusion may be screwed on the upper portion of the cover.

In addition, a heat dissipation plate 424a made of copper or aluminum alloy may be further provided to dissipate heat generated from the light emitting diode array 424 of FIG. 4. However, in other cases, the housing may be configured to take the role of a heat sink, and a cooling fan may be mounted if necessary.

Since the light emitting diode array 424 shown in FIG. 4 has 84 in parallel and 2 in parallel, a total of 168 LEDs constitute a single lamp, it can be seen that the number of parallel connection of the light emitting diode units is greater than the number of serial connections. .

As shown in FIG. 4, the bypass unit 420 shown in FIG. 3 is loaded when the substrate or the LED array is removed from the housing or when some of the LED units do not emit light. Fail and stripping detection unit (ZD, R1, C1, C2 of Figure 5) for detecting as a form of voltage change of the constant current of the power applied to the substrate in response to the detection signal of the detection unit to the LED array of the rear stage And a constant current passing part SCR for applying.

In FIG. 4, when a number of LED units (LED 1 -LED 168) in the LED array 424 fail more than a predetermined number, that is, when the LED units do not emit light, the LED lamps are connected to each other in series. The located LED lamps are all turned off because they do not receive the constant current of the first electrode NO1. Accordingly, the voltage is monitored by the zener diode ZD and the resistor R1 in the fail detection bypass unit 420b, and when the voltage exceeds a predetermined voltage, the thyristor SCR, which is the constant current passing unit, is turned on to indicate an arrow symbol AR1. Current of the first electrode N01, for example, the anode flows in the) direction and is delivered to the bypass node ND10.

In addition, in FIG. 4, the over illuminance bypass unit 420a includes a photo transistor Q1, resistors R1 and R2, and a transistor Q3. As the transistor Q1 is turned on and thus the transistor Q3 is turned on, current of the anode flows in the direction of the arrow AR2 and is transmitted to the bypass node ND10.

The stripping detectors C1 and C2 shown in FIG. 5 are connected to the first node NO1 and the bypass node ND10 of FIG. 4, respectively, and replace and maintain the LED unit or the lamp of FIG. 5. Since the voltage is monitored by the zener diode ZD and the resistor R1 when the substrate 424b is removed, the thyristor SCR is turned on and the current of the first electrode N01 in the direction of the arrow AR1 is similarly increased. Flow is provided to the bypass node ND10.

Reference numeral 428, which is not described in FIG. 3, indicates a manual passing switch SW1 that bypasses the constant current of the power supply to the rear end by manual operation.

Referring to FIG. 7 showing the housing structure of the LED lamp of FIG. 4, the housing 116 shown in FIG. 10 is connected to the rectangular raceway 100 in which the power line or the communication line is accommodated by the fixing connector 111. Installed is shown. Since this shape is like replacing the existing fluorescence as it is, there is no need to replace the existing raceway, contributing to the reduction of the replacement cost. In FIG. 7, 70a is a perspective view of installation of an LED lamp, 70b is a front shape in the longitudinal direction, and 70c is a side cap. In the case of the present embodiment, the size of the side caps S10, S11, S13 and S14 are 53, 41.5, 94 and 160 mm, respectively. 7 compared to FIG. 6 showing the shape of a side surface of a conventional fluorescent lamp, the existing structure is left as it is, only replace the fluorescent lamp with an LED lamp and only the power wiring accordingly, it can be seen that easy replacement construction is implemented. In the case of Fig. 6, LA1 and LA2 indicate two fluorescent lamps, and sizes S1, S2 and S3 are about 60, 26 and 210 mm.

8 and 9 illustrate examples of external appearances of the LED units used in the LED lamp of FIG. 4. In the case of FIG. 8, the general type diffused lighting unit EZBD 23 is indicated. It shows shape. FF and RF show front and back shapes, respectively. Meanwhile, in FIG. 9, the EZ LED of the unidirectional type is shown, and the reflection shade is not necessary. 90a shows one individual shape, and 90b shows a shape in which a plurality of LEDs are assembled.

FIG. 10 exemplarily shows a coupling structure of the housing of FIG. 7 and an installation form with a raceway. When the circuit configuration as shown in Fig. 4 is mounted in the chassis as the lamp housing 116, the side cap 115 and the cover 119 are assembled. The housing 116 is hung on the raceway 100 made of a square frame by the connector 111, and is fixed by the fixing screw 112.

FIG. 11 is a view illustrating examples of situational illumination adjustment steps for the LED lamp of FIG. 4. When the control panel 11a is set to the manual mode, the LED lamp may be maintained on or off or selected in the 0-100% illuminance range by the dimming control of the manual control unit 332 of FIG. 2.

In addition, when the control panel (11a) is set to the automatic mode, the LED lamp is on or off, as well as 40%, 60%, 80%, 90%, etc. It can be shown that can be changed according to the event occurs appropriately.

The illuminance adjustment operation will be described with reference to FIG. 12, which shows an operation control flow related to illuminance adjustment of the LED lighting controller of FIG. 1.

In operation 121, the MPU 330 of FIG. 2 performs initialization. In the initialization step, various ports and UART initialization, timer and converter initialization, and various register initialization are executed.

In step 122, the presence or absence of the automatic mode is checked, or in step 123, the manual mode is checked. In the manual mode, step 124 is executed, and the operation in the manual mode described with reference to FIG. 11 is performed. In the automatic mode, the MPU 330 executes step 126. In step 126, the MPU 330 communicates with the lighting device management server 20 of FIG. 1 through the communication line interface unit 326 of FIG. 2. In this case, since the zone ID of the LED lighting control unit 32 of FIG. 1 is set by the DIP switch 334 of FIG. 2, the lighting apparatus management server 20 of FIG. 1 controls any control unit in the LED lighting control group 30. Be aware of cognition.

In step 127, the MPU 330 determines basic illuminance control data, and outputs the same to the LED driver 322 of FIG. 2. The basic illuminance control data is data determined by receiving a basic illuminance control value from the lighting apparatus management server 20. Accordingly, the LED lamp unit 42 of FIG. 1 emits light with basic illuminance. In this case, when the LED unit LED1 of FIG. 4 emits the maximum light and a current of 60 mA flows, the forward voltage becomes about 3.2V. Therefore, since two LED units are connected in series, the forward voltage is 6.4V, and since the LED lamp 424 has 84 stages in parallel, it is 6.4V / 5A (0.06x84). Thus, one LED lamp is calculated to be about 32W at 100% illumination. Therefore, as shown in FIG. 3, if 30 LED lamps are connected in series between the anode NO1 and the cathode NO2 and driven in a constant current control method, the voltage between the anode and the cathode may be DC 192V (at 100% illumination). 6.4x30). When the basic illuminance is 50%, the illuminance control signal DCS is applied as a signal for controlling the illuminance at 50%. Accordingly, the LED driver 322 controls the constant current, for example, by a pulse width modulation method. Therefore, the LED lamp does not emit light at 100% illuminance, and emits light at as much as 50% illuminance, thereby saving power.

In step 129, it is checked whether the minimum illuminance according to the basic illuminance control data is maintained. The step 129 is achieved by the MPU 330 receiving the sensing signal of the illuminance sensor through the sensor interface 336 of FIG. 2 and comparing it with the set reference signal.

After the step 129 of maintaining the minimum illuminance, it is checked in step 131, 132, 133 whether server data, sensor data, or contact data is received. When data is received in the change request data checking step, the MPU 330 increases or decreases the illumination control signal DCS to adjust the illumination to change the driving constant current. Run through step 160.

In the illumination adjustment step, when the server data is received as a signal generated from a ubiquitous parking information system (UPIS) connected to the RFID receiver, or when an emergency bell or wireless location data is received, as in step 140, 100 %, Or 20-80% illuminance. In addition, when the sensor data is received as a signal generated from a human body or a motion sensor, the intensity is changed to 70-100% as in step 150. Eventually, the illuminance changes from 50% to 100%, thus changing from a dark state to a bright state.

In this way, the illuminance control signal is increased to change the illuminance increased from the minimum illuminance, while the sensor data is received as a transient signal generated from the illuminance sensor or the temperature sensor or the contact data is switched by the emergency power supply switching. When received as a signal, the MPU 330 may reduce the illuminance control signal DCS to vary the illuminance, for example 20%, which is reduced than the minimum illuminance. In the case of overtemperature detection of the temperature sensor, it is natural to reduce the power usage because there is a danger of fire in the lamp. Meanwhile, when the emergency power is turned on, the illuminance may be increased to 80% in the second mode. These are for safe response or evacuation.

When the illumination is adjusted for each zone, the return direction and the outgoing direction are recognized according to which terminal the UPIS signal is generated. If you assume that you are passing through zones A, B, C, and D when you are returning home, if you are in zone A, take only zone A at 100% illuminance and the remaining zones B, C , D can be controlled with 20-80% illuminance. Over time, when the user passes the zone B, only the zone B can be controlled at 100% illuminance and the remaining zones can be controlled at 20-80%. On the other hand, when the UPIS signal is obtained from the door terminal, it is recognized as going out, and in this case, the illumination control may be performed on the D, C, B, A zones in contrast to the return home. This control is implemented by receiving the previous home history data from the UPIS server and referencing it.

In operation 170, a transmission step of storing power usage status data according to the illumination control and defect information according to reception of the fail signal of the array monitoring unit 324 and transmitting the defect information to the lighting apparatus management server 20 is performed. do.

As such, according to the control operation as shown in FIG. 12, the diversification of the lighting control, the convenience of managing the lighting lamp, the reduction of the illumination power, and the convenience of maintenance are achieved.

An operation control flow related to integrated illumination control and monitoring of the lighting management server 20 of FIG. 1 is exemplarily illustrated in FIG. 13.

Referring to FIG. 13, the lighting apparatus management server 20 performs an initialization (step 201) and a LLC (LED Lamp Controller) communication step (step 202), and then communicates with the MPU 330 to perform the operation. It stores statistically the current status of the use of lighting power and defects such as lighting (step 204), and displays or outputs the current status on the screen in response to a request from an operator (steps 206, 208, and 209). Step 210 is performed. Accordingly, the centralized control type lighting control and status can be managed statistically.

When the parking server data or the emergency call signal generated by the parking information management system 10 is received in step 212, the data or signal is transmitted to the corresponding MPU 330 through a communication line in step 214.

When the lighting apparatus management server 20 determines that the seasonal mode is entered in step 216 by mounting a real time clock (RTC), the controller 120 generates an illumination control value for each season, time, day of the week, and ambient brightness by executing step 218. And transmits to the MPU 330. The step 218 may be executed after the step 204.
