Description

  The present invention relates to a light control system that performs light control of a plurality of lighting fixtures.

  In general, the luminous flux of the illumination lamp decreases as the cumulative lighting time elapses. That is, the illuminance decreases as the lamp lighting time is accumulated. For this reason, for example, an illuminance correction device for correcting the lamp lighting power according to the lamp lighting cumulative time and a lighting device incorporating a lighting time timer are disclosed in, for example, Japanese Patent Application Laid-Open No. 2001-15276 (Patent Document 1). Has been proposed.

  The lighting device proposed in Patent Document 1 includes a discharge lamp that is a dimmable lamp, a discharge lamp lighting device, a lighting time detection unit, a lighting time timer, and an illuminance correction device. The power supply to the lamp is detected and the lighting time timer is driven to record the cumulative lighting time, and the discharge lamp lighting device is controlled by the illuminance correction device based on the cumulative time from the lighting time timer. The lighting power supplied to is corrected so that the illuminance increases.

  This lighting device is integrally formed as a type of lighting fixture incorporating the above-described discharge lamp, discharge lamp lighting device, lighting time detection device, lighting time timer, and lighting correction device. The wiring construction of the lighting device can be handled in the same manner as a conventional general lighting fixture that is only connected to a commercial power source.

  On the other hand, dimming systems in which illumination light is dimmed are used for lighting in theaters and studios. This dimming system includes a dimmer for monitoring the lighting power of each lighting fixture and lamp non-lighting, and a dimming main device for monitoring and displaying status monitoring information from these dimmers.

As this light control system, for example, as shown in Japanese Patent Application No. 2002-273554 (Patent Document 2), a state monitoring unit that monitors the operating state of a lighting fixture (including a lamp) and generates state monitoring data, and A communication unit that transmits the state monitoring data by power line carrier communication is incorporated in each lighting fixture. On the other hand, the dimmer that performs dimming control of the luminaire receives the state monitoring data transmitted from the monitor in the luminaire by power line carrier communication and transfers it to the dimming main device that controls the dimmer. . The dimming main device receives the transferred state monitoring data, and displays the operation state of each lighting fixture that is controlled by the dimmer.
Japanese Patent Application Laid-Open No. 2001-15276. Japanese Patent Application No. 2002-273554 (unpublished).

  The illuminating device proposed in Patent Document 1 is integrally formed as a type of lighting fixture incorporating a discharge lamp, a discharge lamp lighting device, a lighting time detection device, a lighting time timer, and a lighting correction device. For this reason, only dimming with respect to the lighting cumulative time of only the discharge lamp built in the lighting fixture and detection of non-lighting are performed.

  In addition, the dimming system shown in Patent Document 2 is basically the same as Patent Document 1 because state monitoring data of a specific lighting fixture connected to the dimmer is generated.

  On the other hand, a dimming system used in a theater, a studio, or the like does not always have a specific lighting fixture fixedly connected to a specific dimmer arranged in a fixed manner. The luminaires connected to it are replaced as necessary.

  That is, there are many cases where the arrangement of a plurality of lighting fixtures is changed according to the contents of the performance performed in a theater or a studio. In other words, use a dimmer or dimmer main unit to monitor the lighting time of a specific lighting fixture, accumulate the lighting duration, and use it for preventive maintenance that issues a warning before the lighting fixture is not turned on. Even so, since the lighting fixture connected to the dimmer changes as necessary, the cumulative lighting time of the specific lighting fixture could not be obtained.

  For this reason, managers such as theaters and studios cannot immediately obtain the fixture information (lamp life, fixture type, light distribution data, etc.) for each of the plurality of lighting fixtures connected to the dimmer.

  In view of such circumstances, the present invention provides dimming capable of notifying monitoring information such as the accurate cumulative lighting time of each lighting fixture and appliance information, regardless of which dimmer is connected to the lighting fixture. The purpose is to provide a system.

Reading information by a machine, or reading identification information in a non-contact manner from an identification tag having a storage unit in which identification information is written and stored, and a communication unit that transmits the identification information stored in the storage unit to the outside There is.

  The identification tag uses an electromagnetic coupling method, an electromagnetic induction method, a microwave method, an optical communication method, etc. as a transmission medium method of identification information, and a read-only type, single writing / reading as an access method of the identification information A dedicated type, a readable / writable type, and the like are used. As a power supply method, an active type with a built-in battery and a passive type supplied from the outside are used. Generally, an RF (Radio Frequency) ID tag and Collectively.

  The reading device reads the identification information written and stored in the RFID tag as the identification tag by the transmission medium method described above. The reader includes a transmission request unit that makes a transmission request for identification information to the RFID tag, a storage unit that receives the identification information transmitted from the RFID tag, and stores the identification information, and the storage unit And a transfer unit that transfers the identification information stored in the light control main device wirelessly or by wire.

  The dimmer of the dimmer supplies lighting power to a lamp that is an illumination load, and adjusts the illuminance by controlling the phase of the lighting power. The monitoring information obtained by the state monitoring unit of the dimmer includes the lighting power of the lamp that is the lighting load, the voltage and current of the lighting power, the lighting time, the input voltage drop, the load short circuit interruption, the overload interruption, the no load, These include leakage, circuit failure, temperature rise, and output level.

  The main dimming device generates and transmits control data for dimming each lighting fixture to multiple dimmers, and stores a dimming program that allows dimming control of each lighting fixture according to the scene of a theater or studio At the same time, the lighting fixture connected to the dimmer is monitored.

  The monitoring contents in this dimming main device are the integrated (cumulative) lighting power calculated for each lighting fixture, the cumulative lighting time, the life or failure determined for each lighting fixture based on the monitoring information of each dimmer It is a determination result.

  As for the lighting time, in the state of lighting with a substantially constant power, a clock means or a time counter is provided in the state monitoring unit of each dimmer, and the lighting time from the start of lighting of each lighting fixture Alternatively, the lighting power amount of each lighting fixture is measured by the state monitoring unit, and the lighting time can be calculated by calculating (dividing) the average lighting power or the rated power.

  In particular, in stage lighting where the temporal change in the degree of dimming is large, it is effective to use the effective lighting time calculated based on the integrated lighting power as monitoring data. In addition, since the cumulative lighting time is recorded in the dimming main device together with the identification information of the dimmer and the lighting fixture connected to the dimmer, the effective cumulative power from the cumulative lighting power for each lighting fixture is recorded. The lighting time can be calculated.

  According to the structure of Claim 1, it becomes possible to create and display the database which can list the monitoring content for every identification information of a lighting fixture, for example, the accumulated lighting time for every lighting fixture. Even when the lighting fixture is connected to each of the plurality of dimmers, both the identification information of the lighting fixture and the dimmer are transmitted and stored in the main light control device. Monitoring information can be generated as a database. For this reason, even if the lighting fixtures are rearranged, use management information for each lighting fixture can be obtained, and a dimming system with high convenience for maintenance management of the lighting fixtures can be obtained.

  According to invention of Claim 1, even if it replaces a lighting fixture with respect to each of several dimmers, it produces | generates the accumulated lighting time etc. which are the monitoring contents for every identification information of a lighting fixture as a database. Therefore, it is possible to realize a dimming system that is very convenient for maintenance management of lighting fixtures used in theaters and studios that require rearrangement of the lighting fixtures.
