The present invention relates to a lighting system for controlling a plurality of lighting fixtures through a single DMX console, and more specifically, using a sequential wireless lighting control method, lighting fixtures over a maximum transmission distance of 1.2km of the current RS485 wired method The present invention relates to a lighting system using a sequential wireless light control method that can easily control the lighting of lighting fixtures even when arranging them, or when it is difficult to install a communication line of RS485 such as a river or a building.

In general, a lighting system in which a plurality of lighting devices are collectively controlled is largely composed of a digital multiplex (DMX) console and various lighting devices that are wired to the DMX console through a wired communication line of RS485, a serial communication protocol standard. It is composed.

DMX is a standard control signal used to control luminaires. It was first specified in 1990 and has since been modified several times to this day. RS485 is a wired serial that increases the transmission distance and the amount of transmission data from tens of meters and tens of kilobits to 1.2km and one megabit, respectively, which is a disadvantage of RS232, a serial communication (serial communication) used fixedly attached to IBM-PC. Communication method.

1 schematically illustrates a lighting system based on a conventional RS485 wired communication system.

Referring to FIG. 1, the DMX console 110 transmits a power control signal set by a user's operation to each lighting device 130a, 130b, 130c via an RS485 communication line 120. Each of the lighting fixtures 130a, 130b, and 130c receives a power control signal transmitted from the DMX console 110 and displays the brightness and color of the corresponding lighting.

In this case, power control signals of various patterns are applied to the respective lighting fixtures 130a, 130b, and 130c, so that lighting and brightness may be individually or simultaneously adjusted for each lighting fixtures 130a, 130b, and 130c, and various effects may be obtained. Can be directed.

However, as the lighting system is diversified and complicated, the lighting system based on the RS485 wired communication system frequently causes the following obstacles.

First, the maximum transmission distance of the RS485 wired communication system is 1.2 km. In some cases, lighting fixtures are installed from the DMX console beyond 1.2 km, which is the maximum transmission distance of the RS485. Difficult to implement In addition, when installing lighting systems such as rivers, mountains, trees, buildings, it is not easy to install a communication line of RS485.

If there are obstacles in the construction of the lighting system as described above, it is necessary to arrange a plurality of DMX consoles, in which case a high cost to install the lighting system.

In addition, when the luminaires are overheated, it is necessary to lower the brightness to lower the temperature inside the luminaire, and in case of the above obstacles, the control becomes difficult.

In addition, when the luminaire is overheated, the pressure inside the luminaire increases, and when the pressure inside the luminaire exceeds the threshold, the sealing of the luminaire may be broken. In this case, the lighting fixture can no longer be kept waterproof, and becomes vulnerable to an environment such as rainfall.

One object of the present invention is to easily control the power supply of lighting fixtures even when the lighting fixtures are disposed over a maximum transmission distance of 1.2 km in the current RS485 wired system or when it is difficult to install a communication line of RS485 such as a river or a building. It is to provide a lighting system using a sequential wireless lighting control method that can control the brightness or color through.

Another object of the present invention is to reduce the power supplied to the lighting device by transmitting information about the overheating to the DMX console when the lighting device constituting the lighting system overheating, and automatically increases the internal pressure due to the lighting device overheating By lowering the pressure, it is to provide a lighting system using a sequential wireless lighting control method that can improve the life characteristics of the lighting fixture constituting the lighting system.

Another object of the present invention is to provide a high quality lighting system by forming a reflective layer on the inner surface of the lighting fixture constituting the lighting system to improve the luminous efficiency of the lamp.

And an N-th sub transceiver sequentially transmitting to the +1 sub transceiver.

In this case, each of the lighting fixtures connected to the first sub-transceiver is equipped with a temperature sensor, each of the temperature sensor transmits an overheating signal to the first sub-transceiver when the sensing temperature of a predetermined temperature or more, and the first sub-transceiver May transmit the overheat signal to the master transceiver.

In addition, each of the lighting fixtures connected to the N-th sub-transceiver is equipped with a temperature sensor, the temperature sensor transmits an overheat signal to the N-th sub transceiver when the temperature sensor detects a temperature above a set temperature, the N-th sub transceiver The N-1 sub transceiver may transmit the overheat signal sequentially to an N-2 sub transceiver (if N is 2, the master transceiver).

The lighting system using the sequential wireless lighting control method according to the present invention wirelessly transmits a power control signal from the master transceiver to the first sub transceiver, the second sub transceiver, etc. sequentially even when the luminaire is far from the DMX console. Therefore, there is an advantage that the lighting system can be easily implemented.

In addition, when the lighting device is overheated, the user can easily adjust the size of the power supplied to the lighting device by transmitting the overheating signal in the reverse order in which the power control signal is transmitted, and automatically adjust the pressure inside the lighting device. By mounting means that can keep the waterproof properties of the luminaire.

In addition, the present invention can form a reflective layer on the inner surface of the case can exhibit a high luminous efficiency to the front, it is possible to implement a high quality lighting system.

Advantages and features of the present invention and methods for achieving them will be apparent with reference to the embodiments described below in detail with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below, but may be implemented in various different forms, only the present embodiments to make the disclosure of the present invention complete, and common knowledge in the art to which the present invention pertains. It is provided to fully inform the person having the scope of the invention, which is defined only by the scope of the claims. Like reference numerals refer to like elements throughout.

Hereinafter, a lighting system using a sequential wireless lighting control method according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 2 schematically illustrates a lighting system using a sequential wireless lighting control scheme according to the present invention, and FIG. 3 shows an example of lighting apparatuses connected to a master transceiver and a first sub transceiver of a DMX console.

Referring to FIG. 2, the illustrated lighting system includes a DMX console 210, a master transceiver 220, a first sub transceiver 230-1, and N-1 (N ≧ 2) sub transceivers 230 -N. It includes.

The digital multiplex (DMX) console 210 outputs a power control signal Vx-y-z that controls the power of each of the plurality of lighting fixtures. Here, x-y-z may be arbitrarily designated. For example, x may designate a corresponding transceiver, y may designate a lighting apparatus connected to the transceiver, and z may designate a signal regarding a power supply of the lighting apparatus. The power control signal Vx-y-z of the DMX console 210 is transmitted to each lighting fixture, so that lighting, brightness and color of each of the lighting fixtures 240-1,..., 240 -N are adjusted.

The master transceiver 220 wirelessly transmits a power control signal Vx-y-z output from the DMX console 210.

As shown in FIG. 3, the first sub transceiver 230-1 is wired to the at least one lighting device 240-1 (320a, 320b, 320c) wirelessly or through an RS485 communication line 310, and the master transceiver Receiving the power control signal (Vx-yz) transmitted from the 220, and outputs the power control signal (Vx-yz) to each of the connected lighting fixtures (240-1). In addition, the first sub transceiver 230-1 wirelessly transmits the power control signal Vx-y-z to the second sub transceiver 230-2.

In this case, it is preferable that the first sub transceiver 230-1 be positioned at the position closest to the master transceiver 220 among the sub transceivers. Of course, when connected to the first sub-transceiver 230-1 via an RS485 communication line, the lighting fixtures must be within 1.2 km, which is the allowable range of the RS485 communication system for normal lighting control.

In the present invention, the power control signal (Vx-yz) output from the DMX console 210 from the master transceiver 220 to the first sub transceiver (230-1), the first sub transceiver (230-1) the second sub The transceiver 230-2 is sequentially wirelessly transmitted. Thus, it is possible to control the lighting of all lighting fixtures even if the lighting fixture is further away from the DMX console 210 than the allowable distance of the RS485 communication system.

In addition, a plurality of sub-transceivers may be arranged, and each sub-transceiver is connected to at least one lighting device wirelessly or wired through an RS485 communication line. The Nth (N is a natural number of two or more) sub transceiver 230-N receives a power control signal transmitted from the N-1 sub transceiver and outputs it to the connected lighting fixture, and wirelessly outputs the power control signal to the N + 1 sub sub. Transmit to the transceiver.

On the other hand, the lighting apparatus generates heat during operation, and in particular, a large amount of heat may be generated inside the lighting apparatus due to an installation place or direct sunlight in summer. The generated heat must be quickly released to the outside through a heat sink or a heat radiating slit, but in some cases, the heat cannot be emitted and the lighting apparatus may be overheated. This may cause damage to various parts of the lighting fixtures, including the lamp, which may cause a shortening of the life of the lighting fixtures.

Accordingly, a temperature sensor 240-1 is mounted to each of the lighting apparatuses 240-1; 320a, 320b, and 320c connected to the first sub transceiver 230-1, and each of the temperature sensors 250-1 is provided with a temperature sensor 240-1. if it detects a temperature above the set temperature, the first sub-in transceiver (230-1) transmits the overheating signal (V _TEM), the first sub-transceivers (230-1) is overheating signal (V _TEM to the master transceiver 220 ) Can be sent sequentially. Through this, the DMX console 210 may output a separate power control signal to adjust the brightness of the corresponding lighting fixture in a direction of decreasing heat generation, and forcibly drive a fan that may be disposed in the lighting fixture to drive the inside of the lighting fixture. The heat of may be released to the outside.

In addition, the temperature sensor 250 -N is mounted not only on the first sub transceiver 230 but also on each of the lighting apparatuses 240 -N connected to other sub transceivers, that is, the Nth sub transceiver 230 -N. When the temperature sensor 250 -N detects a temperature higher than the set temperature, the overheat signal V _TEM is transmitted to the Nth sub transceiver 230 -N, and the Nth sub transceiver 230 -N transmits the N−. The N-1 sub transceiver may sequentially transmit the overheat signal V _TEM to the N-2 sub transceiver (if N is the master transceiver).

This is not a receiver that merely receives the N sub transceivers 230-1, 230-2,..., 230 -N including the first sub transceiver 230-1. This is possible by constructing a possible transceiver.

4 is an external perspective view of an example of a light fixture constituting the lighting system according to the present invention. Here, the lighting apparatus includes a lighting apparatus 240 -N connected to the first transceiver 230-1 and a lighting apparatus 240 -N connected to the other Nth transceiver 230 -N.

Referring to FIG. 4, the illustrated lighting device 400 includes a case 410, a floodlight plate 420, and a lamp 430.

Case 410 constitutes the overall appearance of the lighting fixture 400, the front is open form, the floodlight plate 420 is coupled to the front. The case 410 may be formed of a material such as metal or synthetic resin.

The floodlight plate 420 is coupled to the front surface of the case 410, thereby sealing the inside of the case. Of course, after combining the floodlight plate 420, it is preferable to go through a separate sealing process. The sealing process may be to continuously apply a sealing member along a portion where the floodlight plate 420 and the case 410 are coupled. At this time, the sealing member may be used that is manufactured, sold for the purpose of sealing such as silicone, epoxy, urethane.

The floodlight plate 420 may be transparent glass or glass processed to exhibit a specific color.

The lamp 430 that emits light is mounted on the side or bottom of the case 410.

At this time, the side or bottom of the case 410 may be provided with a cowcket for mounting the lamp 430 mechanically, electrically, in this case, the lamp may be made of a shape having a hydrogenet.

4 shows an example of using a metal halide lamp as a lamp applied to a luminaire. Metal halide lamps exhibit high light efficiency and have good color rendering properties, and are widely used as light sources for landscape lighting and street lamps.

In addition to the lamp 430, a light emitting diode (LED) lamp, a halogen lamp, a sodium lamp, or the like may be used.

Reflecting layer 440 may be formed on the inner surface of the case to increase the luminous efficiency by concentrating the light emitted from the lamp 430 to the front, so as to configure a high quality lighting system.

The reflective layer 440 is 15 to 35 parts by weight of hydroxy ethyl hydroxypropyl cellulose (polycarbonate), 10 to 20 parts by weight, 2-amino with respect to 100 parts by weight of methyl methacrylate-styrene copolymer Phenol-4-sulfonic acid (2-Aminophenol-4-Sulfonic Acid) may be formed of a material containing 7 to 15 parts by weight.

In order to measure the reflectance of the reflective layer made of the above materials, the following experiment was performed.

1. Preparation of Specimen

In Example 1, 100 g of methyl methacrylate-styrene copolymer, 15 g of hydroxyethyl hydroxy propyl cellulose, 10 g of polycarbonate, and 7 g of 2-aminophenol-4-sulfonic acid were mixed using acetone, followed by thickness by injection molding. A 2 mm specimen was made and acetone was volatilized.

In Example 2, 100 g of methyl methacrylate-styrene copolymer, 35 g of hydroxyethyl hydroxy propyl cellulose, 20 g of polycarbonate, and 15 g of 2-aminophenol-4-sulfonic acid were mixed with acetone to prepare a specimen in the same manner as in Example 1. Was produced.

In Example 3, 100 g of methyl methacrylate-styrene copolymer, 25 g of hydroxyethyl hydroxy propyl cellulose, 15 g of polycarbonate, and 10 g of 2-aminophenol-4-sulfonic acid were mixed with acetone to prepare a specimen in the same manner as in Example 1. Was produced.

In Comparative Example 1, 100 g of methyl methacrylate-styrene copolymer, 40 g of hydroxyethyl hydroxy propyl cellulose, 5 g of polycarbonate, and 10 g of 2-aminophenol-4-sulfonic acid were mixed with acetone in the same manner as in Example 1 Specimen was produced.

In Comparative Example 2, 100 g of methyl methacrylate-styrene copolymer, 10 g of hydroxyethyl hydroxy propyl cellulose, 30 g of polycarbonate, and 10 g of 2-aminophenol-4-sulfonic acid were mixed with acetone to prepare a specimen in the same manner as in Example 1. Was produced.

In Comparative Example 3, 100 g of methyl methacrylate-styrene copolymer, 25 g of hydroxyethyl hydroxy propyl cellulose, 15 g of polycarbonate, and 2 g of 2-aminophenol-4-sulfonic acid were mixed with acetone to prepare a specimen in the same manner as in Example 1. Was produced.

In Comparative Example 4, 100 g of methyl methacrylate-styrene copolymer, 20 g of hydroxyethyl hydroxy propyl cellulose, 10 g of polycarbonate, and 20 g of 2-aminophenol-4-sulfonic acid were mixed with acetone to prepare a specimen in the same manner as in Example 1. Was produced.

In Comparative Example 5, a specimen having a thickness of 2 mm was manufactured from an aluminum plate (made by Dongyang Nonferrous Metals).

The compositions shown in Examples 1 to 3 and Comparative Examples 1 to 4 are summarized in Table 1, and the unit is gram (g).

TABLE 1

2. Reflectance Measurement and Evaluation Method

Reflectance was measured using a reflectometer (CM3500d, manufactured by Minolta, Japan) to measure reflectance at wavelengths of 520 nm corresponding to green, 595 nm corresponding to yellow, and 650 nm corresponding to red.

In the evaluation, when the reflectance of silver (Ag) was 100%, the reflectance was 80% or more as good (o), and in the case of less than that, the defect (x) was used.

3. Results and Analysis

The reflectance evaluation results are shown in Table 2.

TABLE 2

Referring to Table 2, in the case of Example 1, the reflectances were all good at 80% or more at 520 nm corresponding to green, 595 nm corresponding to yellow, and 650 nm corresponding to red. However, Comparative Example 1 corresponds to red. At 650 nm, the reflectance did not reach 80% at 520 nm in Comparative Example 2, 595 nm in Comparative Example 3, and 520 nm and 650 nm in Comparative Example 4.

In addition, in the aluminum plate of Comparative Example 5, the reflectance was 85% or more at 595 nm corresponding to yellow, and the reflectance was good at 80% or more at 520 nm corresponding to the remaining green color and 650 nm corresponding to red color. There is a problem that corrosion can easily occur in the environment of the lighting fixture.

Therefore, the reflective layer applied to the lighting fixture can exhibit excellent reflectance even if not a metallic material such as aluminum, and also has a strong resistance to corrosion.

The lighting device 400 includes a power supply (not shown) in addition to the case 410, the floodlight plate 420, and the lamp 430 illustrated in FIG. 4. The power supply unit may be mounted in a space provided on the rear surface of the case 410 or in a space provided on the side surface, and in some cases, may be disposed outside the case.

The power supply unit is connected to an external power source, and adjusts and supplies the power supplied to the lamp 430 in response to the power control signal Vx-y-z. The power supply unit may include various components or circuits for supplying power to the lamp such as a rectifier and a ballast.

On the other hand, when the lamp 430 is driven while the inside of the case 410 is sealed, the temperature inside the case 410 is gradually increased. Accordingly, the pressure inside the case 410 also increases. When the pressure inside the case 410 is above a predetermined pressure, that is, the limit pressure, a gap may occur in a relatively weak sealing part.

In this case, a complete seal can no longer be achieved and must be sealed again. If there is damage to the lamp or other parts due to the inflow of rainwater, there is a problem in that the corresponding parts or the lighting fixtures must be replaced.

Therefore, the pressure inside the case 410 must be maintained at a constant level to maintain the sealing continuously.

Accordingly, the lighting apparatus connected to the first sub transceiver and the Nth sub transceiver may include a pressure adjusting means for adjusting the pressure therein.

Figure 5 is a block diagram schematically showing a pressure regulating means.

Referring to FIG. 5, the illustrated pressure regulating means 500 includes a pressure sensor 510, a pressure controller 520, and a valve 530.

The pressure sensor 510, the pressure controller 520, and the valve 530 constituting the pressure regulating means 500 may be separately configured, and may be integrally formed. In addition, the pressure sensor 510, the pressure controller 520, and the valve 530 may be separately connected to an external power source, and may be electrically connected to a power supply unit supplying power to the lamp 430.

The pressure sensor 510 is mounted on the inner surface of the case 410 constituting the lighting fixture. The pressure sensor 510 senses the pressure inside the sealed case and outputs a pressure value C _in corresponding to the sensed pressure to the pressure controller 520.

The pressure controller 520 may be mounted on the side or the back of the case 410. The pressure controller 520 uses the pressure value C _in output from the pressure sensor 510 to open the valve 530 when the pressure corresponding to the pressure value is greater than or equal to the set pressure. Outputs (V _open ) and also transmits the overpressure signal (V _COM ) to the sub transceiver connected to the luminaire. The overpressure signal V _COM transmitted may be transmitted to the DMX console 210 through the master transceiver 220 through sequential wireless communication similarly to the overheat signal V _TEM .

That is, when the sub transceiver connected to the pressure controller 520 is the first sub transceiver 230-1, the pressure controller 520 is the first sub transceiver 230-1 and the first sub transceiver 230-1. ) May sequentially transmit the overpressure signal V _COM to the master transceiver 220.

In addition, when the sub transceiver connected to the pressure controller 520 is an N-th sub transceiver 230 -N other than the first sub transceiver 230-1, the pressure controller 520 is an N-th sub transceiver ( 230-N), the Nth sub transceiver 230-N is the N-1 sub transceiver, the N-1 sub transceiver is the N-2 sub transceiver (where N is 2, the master transceiver). The overpressure signal V _COM may be sequentially transmitted.

The valve 530 is mounted on the back or side of the case to allow the exhaust to the outside of the case.

The valve 530 is opened in response to the valve open signal V _open output from the pressure controller 520. As the valve 530 is opened, the exhaust is exhausted to lower the pressure inside the case 410. Therefore, the case 410 may maintain a predetermined level of pressure even when driving of the lamp is continued.

The opening of the valve 530 can solve the problem of damage to the seal due to the internal pressure rise, which is a conventional problem, the lighting fixture having a pressure control means can continue to maintain the waterproof characteristics.

FIG. 6 is a block diagram schematically illustrating an example of the pressure controller shown in FIG. 5.

Referring to FIG. 6, the pressure controller 520 according to the illustrated example includes an input unit 610, a comparator 620, and an output unit 630.

The input unit 610 receives a pressure value C _in from the pressure sensor 510.

The comparison unit 620 outputs a result signal by comparing the pressure value C _in and the set value C _th output from the input unit 610. For example, when the pressure value C _in is smaller than the set value C _th (C _in <C _th ), '0' corresponding to a signal for not opening the valve 530 is output, and the pressure value ( When C _in ) is equal to or greater than the set value C _th (C _in ≧ C _th ), a “1” corresponding to a signal for opening the valve 530 is output.

The output unit 630 determines the result signal output from the comparator 620, and when the result signal corresponds to a signal for opening the valve 530 ('1' in the above example), the valve open signal V _open ) is output to the valve 530. In addition, the output unit 630 transmits an overpressure signal V _COM to a sub transceiver connected to the corresponding lighting fixture.

In this case, the output unit 630 may be connected to the timer 640 to output the valve open signal V _open for a predetermined time, and may output a signal for automatically closing the valve 530 after a predetermined time elapses. In this case, the valve 530 is opened only when the set value is higher than the set value specified by the internal pressure rise of the case 410, and automatically closes again after a predetermined time, that is, when the valve is opened, the valve is artificially opened again. The advantage is that no closing process is required.

7 illustrates an example in which a sub transceiver and an LED luminaire are wirelessly connected.

Referring to FIG. 7, a transceiver 710, such as a first sub transceiver or an Nth sub transceiver, may be connected to a plurality of LED lighting fixtures 720 provided with an antenna 720a wirelessly through an antenna 710a. have.

As described above, the lighting system using the sequential wireless lighting control method according to the present invention is a power control signal sequentially from the master transceiver to the first sub-transceiver, the second sub-transceiver, etc. even when the luminaire is far from the DMX console. By transmitting wirelessly, there is an advantage that can easily implement a lighting system.

In addition, when the luminaire is overheated, it is possible to adjust the size of the power supplied to the luminaire by transmitting the overheat signal in the reverse order in which the power control signal is transmitted. The waterproof property can be maintained continuously. In addition, by forming a reflective layer on the inner surface of the case can exhibit a high luminous efficiency to the front, it is possible to implement a high-quality lighting system.
