Description

本発明は、独立型内照式看板の技術に関し、より詳細には、LED光源部からの照射光により広告面が内照される照明部を具備してなる独立型内照式看板に関する。   The present invention relates to a technology for a stand-alone internally illuminated signboard, and more particularly, to a stand-alone internally illuminated signboard comprising an illuminating section in which an advertising surface is internally illuminated by light emitted from an LED light source section.

従来、例えば、特許文献1に開示されるように、LED光源部からの照射光により広告面が内照される照明部を具備してなる独立型内照式看板の構成が公知であり、具体的には、太陽光エネルギーにより電力を出力する太陽電池と、太陽電池より出力された電力を充電する蓄電池とを具備してなり、昼間には太陽電池から蓄電池へと電力を供給して充電し、夜間には蓄電池に蓄えられた電力を放電して照明部を点灯させるように構成されている。   Conventionally, for example, as disclosed in Patent Document 1, a configuration of a stand-alone internally illuminated signboard including an illumination unit in which an advertisement surface is internally illuminated by light emitted from an LED light source unit is known. Specifically, a solar battery that outputs electric power by solar energy and a storage battery that charges the electric power output from the solar battery are provided, and the electric power is supplied from the solar battery to the storage battery for charging in the daytime. In the nighttime, the power stored in the storage battery is discharged to turn on the illumination unit.

上述したような独立型内照式看板では、照明による広告効果を発揮させるためにも、夜間に照明部が突然消灯することなく照明部を安定して点灯維持できることが求められる。昼間に太陽光エネルギーを蓄電して夜間に照明を行うため、昼間に太陽電池にて十分な発電量が得られないと、夜間に蓄電池の残存容量が不足して消灯時刻まで照明部の点灯を維持できない。特に、内照式看板が都市部や郊外に設置される大型の広告用看板として構成される場合に、夜間の蓄電池の残存容量不足を解消するために、太陽電池の発電量や蓄電池の充電容量を物理的に増加させる方法では装置コストがかかり、また、特許文献1に開示されるように商用電源と接続して蓄電池による電力不足を補う方法では、商用電源と接続できない場所に設置できないため使用が制限されてしまうなどの問題があった。   In the above-described independent interior-lit signboard, in order to exhibit the advertising effect by illumination, it is required that the illumination unit can be stably lit and maintained without suddenly turning off the illumination unit at night. Since solar energy is stored in the daytime and illuminated at night, if there is not enough power generated by solar cells in the daytime, the remaining capacity of the storage battery is insufficient at night and the lighting unit is turned on until the turn-off time. It cannot be maintained. In particular, when an internally illuminated signboard is configured as a large advertising signboard installed in an urban area or suburb, the amount of power generated by the solar battery or the charge capacity of the storage battery is used to resolve the shortage of remaining storage battery capacity at night. The method of physically increasing the power consumption requires apparatus cost, and as disclosed in Patent Document 1, the method of compensating for the power shortage caused by the storage battery by connecting to a commercial power source cannot be installed in a place where it cannot be connected to the commercial power source. There were problems such as being restricted.

とりわけ、2011年3月の東日本大震災を契機に全国的に節電対策が開始され、節電対策の緊急措置として、夜間に点灯する内照式やライトアップ方式等の広告用看板の消灯や自粛が行われたことは記憶に新しい。その結果、広告用看板を使った商品やイベント情報等のPRの機会が失われ、企業の宣伝活動に支障が生じることとなった。また、広告主である企業が夜間の広告用看板への広告掲出の自主規制や自粛に努めたことにより、広告業界も大きな打撃を受ける事態となり、特に都市部における広告業界の経済活動の実質的損失に発展した経緯もある。このような昨今の社会的要求に応えるためにも、外部電源(商用電源)に依存せず節電対策の影響を受けない独立型の看板が希求されているところである。   In particular, power saving measures began nationwide in the wake of the Great East Japan Earthquake in March 2011, and as an emergency measure for power saving measures, advertising signs such as the interior lighting type and the light-up method that turn on at night are turned off and self-restraint. What has been lost is new to memory. As a result, PR opportunities for products and event information using advertising billboards were lost, which hindered corporate promotional activities. In addition, the advertising industry has been hit hard by the self-regulation and self-restraint of advertising posting on nighttime advertising billboards. There are also circumstances that led to losses. In order to meet these social demands, there is a demand for an independent signboard that does not depend on external power sources (commercial power sources) and is not affected by power saving measures.

かかる観点から、従来の照明装置に関し、照明部の電力消費を抑制して夜間の蓄電池の残存容量不足を軽減する方法が提案されており、例えば、特許文献2には、夜間は人感センサが人を検出しないときは第一の発光状態で光源を発光させ、人感センサが人の存在を検出したときは第一の発光状態よりも明るい第二の発光状態で光源を発光させる方法が開示されている。また、特許文献3には、蓄電池の電圧値が一定以下である場合に、所定領域における照度を一定以上に維持しつつ、他の領域における照度を低下させる方法が開示されている。   From this point of view, a method for reducing power consumption of a lighting unit and reducing a shortage of remaining capacity of a storage battery at night is proposed with respect to a conventional lighting device. For example, Patent Document 2 discloses a human sensor at night. Disclosed is a method of causing a light source to emit light in a first light emitting state when no person is detected, and causing a light source to emit light in a second light emitting state that is brighter than the first light emitting state when the human sensor detects the presence of a person Has been. Patent Document 3 discloses a method of reducing the illuminance in other areas while maintaining the illuminance in a predetermined area above a certain level when the voltage value of the storage battery is below a certain level.

しかしながら、特許文献2に開示される方法は、常時点灯が要求される広告用看板などには採用できない。また、特許文献3に開示される方法では、太陽電池の発電量が所定電力値まで減少すると照明部が点灯し、発電量が所定電力値以上に増加すると消灯するように点灯制御されるため、日射量、気候、気温、周辺照度などの設置環境の変化により照明部の点灯時刻や消灯時刻が実際の日の入り時刻や日の出時刻と一致せず、また秋季や冬季では、太陽電池の発電量が少ないにもかかわらず夜間が長くなって照明部の点灯時間が長くなるなど、外部の不確定要因により点灯時刻や点灯時間などの照明条件にバラつきが生じてしまう。   However, the method disclosed in Patent Document 2 cannot be used for advertising billboards that are always required to be lit. Further, in the method disclosed in Patent Document 3, the lighting unit is turned on when the power generation amount of the solar cell is reduced to a predetermined power value, and is controlled to be turned off when the power generation amount exceeds the predetermined power value. Due to changes in the installation environment such as the amount of solar radiation, climate, temperature, ambient illumination, etc., the lighting time and lighting time of the lighting unit do not match the actual sunset time and sunrise time, and the amount of power generated by the solar cell is small in autumn and winter Nevertheless, lighting conditions such as lighting time and lighting time vary due to external uncertain factors such as longer nighttime and longer lighting time of the lighting unit.

The illumination state of the illumination unit 4 is switched between a lighting state (lighting / extinguishing) according to a lighting time T1 and a lighting time ΔT set by the arithmetic processing unit 55, and dimming set by the arithmetic processing unit 55. Dimming is switched by the pattern (see FIGS. 10 and 11).

演算処理部55は、各種演算処理プログラムや制御プログラムの命令を実行するCPU、該プログラムを記憶するROM、該プログラムを展開するRAM、該プログラム及び各種データを格納するメモリ等の記憶装置(記憶媒体)、タイマ機能としてのクロック、及び保守用コンピュータなどの入出力用機器6に接続してデータを伝送する入出力インターフェース等とで構成されており、上述した効率制御部52、充電制御部53及び点灯制御部54等を制御して独立型内照式看板1を駆動制御するものである。本実施例の演算処理部55には、照明情報部55a、設置場所設定部55b及びログ情報記憶部55cが設けられており、照明部4を点灯/調光制御するための点灯時刻T1及び点灯時間ΔT並びに調光パターンを設定する。   The arithmetic processing unit 55 is a storage device (storage medium) such as a CPU that executes instructions of various arithmetic processing programs and control programs, a ROM that stores the programs, a RAM that expands the programs, and a memory that stores the programs and various data. ), A clock as a timer function, and an input / output interface that transmits data by connecting to an input / output device 6 such as a maintenance computer, and the above-described efficiency control unit 52, charge control unit 53, and the like. The lighting control unit 54 and the like are controlled to drive and control the independent internal signboard 1. The arithmetic processing unit 55 of the present embodiment is provided with an illumination information unit 55a, an installation location setting unit 55b, and a log information storage unit 55c, and a lighting time T1 and lighting for controlling lighting / dimming control of the lighting unit 4 The time ΔT and the dimming pattern are set.

照明情報部55aは、設置場所別の所定月日ごとの日の入り時刻及び日中時間などに関する照明情報を格納している。「照明情報」には、設置場所別の1年間の月日ごと(例えば365日)の日の入り時刻、日中時間、平均降水量、又は日照時間など照明部4の点灯時刻T1及び点灯時間ΔTを設定するために必要なデータが含まれる。「設置場所」とは、独立型内照式看板1が設置される地域や緯度経度により特定される場所情報のことをいう。日照時間は、一般的に降水量が少ない地域で多い傾向があり、可照時間(雲等が影響しない場合の日照可能である時間数)が緯度の関係で長い地域でも日照時間が多くなる。可照時間に対する日照時間の割合を日照率(%)で示すことがある。   The illumination information section 55a stores illumination information related to the sunset time and daytime for each predetermined month and day by installation location. The “lighting information” includes the lighting time T1 and lighting time ΔT of the lighting unit 4 such as the sunset time, daytime time, average precipitation amount, or sunshine time of each month (for example, 365 days) for one year by installation location. Contains the data necessary for setting. “Installation location” refers to location information specified by the area and latitude / longitude where the stand-alone internally illuminated signboard 1 is installed. Sunlight hours generally tend to be high in regions where precipitation is low, and daylight hours increase even in regions where the light time (the number of hours in which sunlight is possible when clouds or the like do not affect) is long due to the latitude. The ratio of the sunshine hours to the sunshine hours may be indicated by the sunshine rate (%).

照明情報は、演算処理部55に接続された入出力用機器6により照明情報部55aへ上書き可能に入力される。日の入り時刻、日中時間、平均降水量、及び日照時間等の平年値は気象統計情報として地域別に記録、公表されており、本実施例ではこれらの公表値を用いることができる。例えば、図5に示すように、複数の都市(都市A〜都市E)を特定した場合には、都市別に月日ごとの日の入り時刻のグラフで表される照明情報がデータシートに格納される。   The illumination information is input to the illumination information unit 55a by the input / output device 6 connected to the arithmetic processing unit 55 so as to be overwritten. Normal values such as sunset time, daytime, average precipitation, and sunshine hours are recorded and published as weather statistical information by region, and these published values can be used in this embodiment. For example, as shown in FIG. 5, when a plurality of cities (city A to city E) are specified, lighting information represented by a graph of sunset time for each month and day is stored in the data sheet.

設置場所設定部55bは、所定の選択操作を可能な切り換えスイッチ等として構成されている。設置場所設定部55bにて設置場所の選択操作が行わることで、上述した照明情報部55aに格納された照明情報の内、所定の設置場所に対応した照明情報が選択される。   The installation location setting unit 55b is configured as a changeover switch or the like capable of a predetermined selection operation. By performing an installation location selection operation in the installation location setting unit 55b, illumination information corresponding to a predetermined installation location is selected from the illumination information stored in the illumination information unit 55a.

本実施例の独立型内照式看板1では、点灯時刻T1は日の入り時刻に基づいて演算し、点灯時間ΔTは、例えば、点灯時刻T1から所定時間(例えば6時間)に一定に設定してもよく、また、深夜以降の時間帯で常時点灯させておく必要性に乏しいので、午前0時〜午前2時の間で消灯時刻T2を一定に設定して、かかる消灯時刻T2と点灯時刻T1とを差分することで演算してもよい。   In the stand-alone internally illuminated signboard 1 of this embodiment, the lighting time T1 is calculated based on the sunset time, and the lighting time ΔT is set to a predetermined time (for example, 6 hours) from the lighting time T1, for example. Well, since it is not necessary to keep the light on all the time after midnight, the light-off time T2 is set constant between midnight and 2 am, and the difference between the light-off time T2 and the light-on time T1 You may calculate by doing.

演算処理部55にて設定する点灯時刻T1及び点灯時間ΔTとしては、例えば、1年間の季節周期において夏季と冬季とでは、日の入り時刻や日中時間が異なり、夏季では日の入り時刻が遅く日中時間が長い一方で冬季では日の入り時刻が早く日中時間が短いことから、図6に示すように、消灯時刻T2(例えば午前0時に消灯)を一定に設定した場合に、春季や秋季での点灯時刻T1及び点灯時間ΔTに対して(図6(a))、夏季では点灯時刻T1は遅い時刻に設定され、点灯時間ΔTが短くなるように設定される(図6(b))。一方、冬季では点灯時刻T1は早い時刻に設定され、点灯時間ΔTが長くなるように設定される(図6(c))。   As the lighting time T1 and the lighting time ΔT set by the arithmetic processing unit 55, for example, the sunset time and the daytime are different in the summer and winter in the seasonal cycle of one year, and the sunset time is late in the summer. On the other hand, since the sunset time is early and the daylight time is short in winter, the lighting time in spring and autumn is set when the lighting time T2 (for example, lighting at midnight) is set constant as shown in FIG. With respect to T1 and lighting time ΔT (FIG. 6A), in summer, the lighting time T1 is set to a later time and the lighting time ΔT is set to be shorter (FIG. 6B). On the other hand, in winter, the lighting time T1 is set to an early time, and the lighting time ΔT is set to be long (FIG. 6C).

また、演算処理部55にて設定する調光パターンとしては、例えば、図7(a)に示すように、照明部4を点灯時間ΔTの間で所定照度Lに維持して調光する直線状の調光パターンに設定してもよい。また、図7(b)に示すように、点灯時刻T1から所定の時刻T3までの間は所定照度(標準照度)Lに対して照度を上げて高照度LHで調光し、所定の時刻T4から消灯時刻T2までの間は標準照度Lに対して下げて低照度LLで調光し、その他の時間は標準照度Lに維持して調光するなどの非直線状のパターンに設定してもよい。調光パターンにおける照度(標準照度L、高照度LH、低照度LL)は、広告看板として媒体価値を担保した基本性能を満たすように好ましく設定される。   In addition, as a dimming pattern set by the arithmetic processing unit 55, for example, as shown in FIG. 7A, a linear shape for dimming while maintaining the illumination unit 4 at a predetermined illuminance L during the lighting time ΔT. The light control pattern may be set as follows. Further, as shown in FIG. 7B, during the period from the lighting time T1 to the predetermined time T3, the illuminance is increased with respect to the predetermined illuminance (standard illuminance) L, and the light is adjusted with the high illuminance LH, and the predetermined time T4 is reached. Even if it is set to a non-linear pattern such as lowering from the standard illuminance L and dimming with the low illuminance LL, and maintaining the standard illuminance L for other times, Good. The illuminance (standard illuminance L, high illuminance LH, and low illuminance LL) in the dimming pattern is preferably set so as to satisfy the basic performance that guarantees the medium value as an advertising billboard.

本実施例の演算処理部55では、設置環境に応じて点灯時刻T1及び点灯時間ΔT並びに調光パターンを最適化して設定する。「設置環境」とは、独立型内照式看板1が設置される場所における日射量、気候、気温(温度)、周辺照度、及び当該設置場所におけるビル陰などの周辺環境の構造的影響に関する情報など独立型内照式看板1の照明条件に影響を及ぼす外部要因(データ)のことをいう。これらの設置環境に関するデータは、例えば、日射量は、出力検知部50により検知された太陽電池パネル2の発電量(発電電力)に応じた計測データ(電圧及び電流)から演算され、温度や周辺照度は、図示せぬ温度計や照度計より入力される観測データより得られる。   In the arithmetic processing unit 55 of this embodiment, the lighting time T1, the lighting time ΔT, and the dimming pattern are optimized and set according to the installation environment. “Installation environment” refers to information on the structural effects of the surrounding environment, such as the amount of solar radiation, climate, temperature (temperature), ambient illuminance, and the shadow of the building at the location where the stand-alone interior-lit signboard 1 is installed. This refers to external factors (data) that affect the lighting conditions of the stand-alone internally illuminated signboard 1. For example, the amount of solar radiation is calculated from measurement data (voltage and current) corresponding to the power generation amount (generated power) of the solar cell panel 2 detected by the output detection unit 50, and the temperature related to the installation environment. The illuminance is obtained from observation data input from a thermometer or illuminometer (not shown).

特に、本実施例では、出力検知部50により検知された太陽電池パネル2の発電量(発電電力)に応じて、設置場所においてビル陰の影響を受けて日射量が少ないと判断した場合には、照明部4での消費電力を抑えるように、例えば、点灯時間ΔTを短くするか調光パターンにおける照度Lを下げて設定する。一方で、設置場所の日射量が多いと判断した場合には、照明部4での消費電力を上げるように、例えば、点灯時間ΔTを長くするか調光パターンにおける照度Lを上げて設定する。   In particular, in this embodiment, when it is determined that the amount of solar radiation is small due to the influence of the shade of the building at the installation location according to the power generation amount (generated power) of the solar cell panel 2 detected by the output detection unit 50. For example, the lighting time ΔT is shortened or the illuminance L in the dimming pattern is lowered so as to suppress power consumption in the illumination unit 4. On the other hand, when it is determined that the amount of solar radiation at the installation location is large, for example, the lighting time ΔT is set longer or the illuminance L in the dimming pattern is set to increase the power consumption in the illumination unit 4.

また、図示せぬ照度計等より入力されるデータより設置場所の周辺照度が高いと判断した場合(都市部など)には、広告面(FFシート42)を明るく照らし出して広告効果を高めるように、例えば、調光パターンにおける照度Lを上げて設定する。一方で、設置場所の周辺照度が低いと判断した場合(郊外など)には、広告面(FFシート42)を明るく照らし出す必要がなくかつ長時間の広告効果を狙って、例えば、点灯時間ΔTを長くしてかつ調光パターンにおける照度Lを下げて設定する。   In addition, when it is determined that the illuminance around the installation location is higher than the data input from an illuminometer (not shown) or the like (urban area, etc.), the advertisement surface (FF sheet 42) is brightly illuminated to enhance the advertising effect. For example, the illuminance L in the dimming pattern is increased and set. On the other hand, when it is determined that the illuminance around the installation location is low (such as in the suburbs), it is not necessary to brightly illuminate the advertising surface (FF sheet 42) and, for example, a lighting time ΔT is aimed at a long-term advertising effect. Is set to be long and the illuminance L in the dimming pattern is lowered.

このように、本実施例の独立型内照式看板1では、照明部4を駆動制御する前に予め設置環境に応じて点灯時刻T1及び点灯時間ΔT並びに調光パターンを設定するものであるが、それらの設定方法としては、演算処理部55にて演算処理されて自動的に設定されてもよく、また入出力用機器6を介してオペレータにより手動で設定されてもよい。演算処理部55にて自動設定される場合には、例えば、出力検知部50により検知された太陽電池パネル2の発電量(発電電力)に応じて、発電量が少ない場合には点灯時間ΔTを短くするか調光パターンにおける照度Lを下げ、一方、発電量が場合には、点灯時間ΔTを長くするか調光パターンにおける照度Lを上げるように自動的に設定される。   As described above, in the stand-alone internally illuminated signboard 1 of the present embodiment, the lighting time T1, the lighting time ΔT, and the dimming pattern are set in advance according to the installation environment before the lighting unit 4 is driven and controlled. As these setting methods, calculation processing may be performed automatically by the calculation processing unit 55, or may be set manually by an operator via the input / output device 6. When the calculation processing unit 55 automatically sets, for example, depending on the power generation amount (generated power) of the solar cell panel 2 detected by the output detection unit 50, the lighting time ΔT is set when the power generation amount is small. On the other hand, the illuminance L in the dimming pattern is automatically set to decrease or decrease the illuminance L in the dimming pattern.

ログ情報記憶部55cには、太陽電池パネル2に関する情報(出力電流及び出力電圧など)、蓄電池3に関する情報(電圧値、充電電流、放電電流及び残存容量など)、設置環境に関する情報(日射量、気候、気温(温度)、及び周辺照度など)などがログデータとして記憶される。このログ情報記憶部55cに記憶されたログ情報は、入出力用機器6より取り出し可能とされる。設置環境に関する情報は、直接又は情報処理された後に上述した照明情報として照明情報部55aに格納されるようにしてもよい。   The log information storage unit 55c includes information on the solar battery panel 2 (output current and output voltage, etc.), information on the storage battery 3 (voltage value, charging current, discharge current, remaining capacity, etc.), information on the installation environment (sunlight amount, Climate, temperature (temperature), ambient illumination, etc.) are stored as log data. The log information stored in the log information storage unit 55 c can be taken out from the input / output device 6. The information regarding the installation environment may be stored in the illumination information unit 55a as the illumination information described above directly or after being processed.

次に、制御部5による独立型内照式看板1の制御動作について、以下に詳述する。
本実施例の独立型内照式看板1は、上述したように予め設置環境に応じて設置場所別に1年間の月日ごとの点灯時刻T1及び点灯時間ΔT並びに調光パターンが設定され、駆動制御を開始すると、まず現在時刻が昼間であるか夜間であるかを判断する。このとき、夜間とは点灯時刻T1から消灯時刻T2の間の時間帯をいい、昼間とはそれ以外の時間帯をいう。その結果、現在時刻が昼間であると判断した場合には、充電制御モードに切り換えて、演算処理部55からの充電制御信号により充電制御部53にて充電制御を行う(S101〜S105)。一方、夜間であると判断した場合には、点灯/調光制御モードに切り換えて、演算処理部55からの点灯制御信号により点灯制御部54にて照明部4の点灯/調光制御を行う(S110〜S115)。
Next, the control operation of the stand-alone internally illuminated signboard 1 by the control unit 5 will be described in detail below.
As described above, the stand-alone internally illuminated signboard 1 of the present embodiment is preset with the lighting time T1 and lighting time ΔT and the dimming pattern for each month and year for each installation location according to the installation environment. First, it is determined whether the current time is daytime or nighttime. At this time, night refers to the time zone between the lighting time T1 and the turn-off time T2, and daytime refers to other time zones. As a result, when it is determined that the current time is daytime, the charging control mode is switched to the charging control mode, and the charging control unit 53 performs charging control based on the charging control signal from the arithmetic processing unit 55 (S101 to S105). On the other hand, when it is determined that it is nighttime, the lighting / dimming control mode is switched to, and the lighting control unit 54 performs lighting / dimming control of the lighting unit 4 by the lighting control signal from the arithmetic processing unit 55 ( S110 to S115).

図8に示すように、充電制御モードでは、出力検知部50にて検知される太陽電池パネル2の発電電力が所定電圧値以上であれば(S101)、充電可能な充分な発電量が確保されていると判断して、充電状態に切り換えて蓄電池3の充電を行う(S102)。充電状態では、演算処理部55より送信された充電制御信号に基づいて、充電制御部53にて太陽電池パネル2から効率制御部52を介して出力された出力電力を蓄電池3へ給電(充電)する。また、充電状態にあるときは、演算処理部55より送信されたMPPT制御信号に基づいて、効率制御部52にて太陽電池パネル2の発電電圧を昇圧又は降圧して、かかる発電電力に応じて最大電力を得るように太陽電池パネル2の動作を制御する。   As shown in FIG. 8, in the charge control mode, if the generated power of the solar battery panel 2 detected by the output detector 50 is equal to or higher than a predetermined voltage value (S101), a sufficient power generation amount that can be charged is secured. The storage battery 3 is charged by switching to the charged state (S102). In the charging state, based on the charging control signal transmitted from the arithmetic processing unit 55, the output power output from the solar cell panel 2 via the efficiency control unit 52 by the charging control unit 53 is supplied to the storage battery 3 (charging). To do. Further, when the battery is in a charged state, the efficiency control unit 52 boosts or lowers the power generation voltage of the solar cell panel 2 based on the MPPT control signal transmitted from the arithmetic processing unit 55, and according to the generated power. The operation of the solar cell panel 2 is controlled so as to obtain the maximum power.

充電状態において、容量検知部51にて検知される蓄電池3の残存容量が所定容量以上でなければ(S103)、蓄電池3が満充電に至っていないと判断して充電状態を継続する。一方、容量検知部51にて検知される蓄電池3の残存容量が所定容量以上であれば(S103)、蓄電池3が満充電になったと判断して、待機状態に切り換えて蓄電池3への充電を行わない(S104)。   In the charged state, if the remaining capacity of the storage battery 3 detected by the capacity detection unit 51 is not equal to or greater than the predetermined capacity (S103), it is determined that the storage battery 3 has not been fully charged and the charged state is continued. On the other hand, if the remaining capacity of the storage battery 3 detected by the capacity detector 51 is equal to or greater than the predetermined capacity (S103), it is determined that the storage battery 3 is fully charged, and the storage battery 3 is charged by switching to a standby state. Not performed (S104).

出力検知部50にて検知される太陽電池パネル2の発電電力が所定電圧値以下であれば(S101)、充電可能な充分な発電量が確保されていないと判断して、待機状態に切り換えて蓄電池3への充電を行わない(S104)。例えば、昼間であっても、天候によっては太陽電池パネル2にて充電可能な充分な発電量が安定して得られず、待機状態と充電状態とを切り換える場合や、点灯時刻T1になるまで待機状態を維持したままの場合なども想定される。   If the generated power of the solar battery panel 2 detected by the output detector 50 is less than or equal to a predetermined voltage value (S101), it is determined that a sufficient amount of power that can be charged is not secured, and the standby state is set. The storage battery 3 is not charged (S104). For example, even during daytime, a sufficient amount of power generation that can be charged by the solar battery panel 2 is not stably obtained depending on the weather, and when switching between the standby state and the charged state, or until the lighting time T1 is reached. The case where the state is maintained is also assumed.

そして、点灯時刻T1になると(S105)、蓄電池3が満充電であるか否かにかかわらず充電制御モードを終了して点灯/調光制御モードに切り換える。   When the lighting time T1 is reached (S105), the charge control mode is terminated and switched to the lighting / dimming control mode regardless of whether or not the storage battery 3 is fully charged.

図9に示すように、点灯/調光制御モードでは、容量検知部51にて検知される蓄電池3の残存容量が最低値VL以上であれば(S110)、蓄電池の残存容量に応じて所定の調光パターンを設定し、照明部4を点灯させる(S111)。点灯状態では、演算処理部55より送信された点灯制御信号に基づいて、点灯制御部54にて蓄電池3から照明部4のLEDコントローラ41dへ出力される電流値を制御して照明部4の点灯・消灯・調光を切り換える。なお、点灯制御部54では、電流値の制御ではなく、PWM制御により出力電力のON/OFFデューティ比を変化させて照明部4の点灯・消灯・調光を切り換えるようにしてもよい。   As shown in FIG. 9, in the lighting / dimming control mode, if the remaining capacity of the storage battery 3 detected by the capacity detection unit 51 is equal to or greater than the minimum value VL (S110), a predetermined value is set according to the remaining capacity of the storage battery. A dimming pattern is set, and the illumination unit 4 is turned on (S111). In the lighting state, based on the lighting control signal transmitted from the arithmetic processing unit 55, the lighting control unit 54 controls the current value output from the storage battery 3 to the LED controller 41d of the lighting unit 4 to turn on the lighting unit 4.・ Switches off and dimming. The lighting control unit 54 may switch on / off / dimming the lighting unit 4 by changing the ON / OFF duty ratio of the output power by PWM control instead of controlling the current value.

点灯状態において、容量検知部51にて検知される蓄電池3の残存容量が所定閾値以下に低下していなければ(S112)、その調光パターンのままで点灯状態を継続する。一方、容量検知部51にて検知される蓄電池3の残存容量が所定閾値以下に低下していれば(S112)、蓄電池3の残存容量に応じて消費電力の少ない所定の調光パターンに切り換えて点灯状態を継続する(S113)。   In the lighting state, if the remaining capacity of the storage battery 3 detected by the capacity detection unit 51 has not decreased below a predetermined threshold value (S112), the lighting state is continued with the dimming pattern. On the other hand, if the remaining capacity of the storage battery 3 detected by the capacity detection unit 51 has fallen below a predetermined threshold (S112), switch to a predetermined dimming pattern with less power consumption according to the remaining capacity of the storage battery 3. The lighting state is continued (S113).

容量検知部51にて検知される蓄電池3の残存容量が最低値VL以下であれば(S110)、蓄電池3において照明部4を点灯可能な電力量が確保できないと判断して、照明部4を消灯させる(S115)。そして、消灯時刻T2になると(S114)、照明部4を消灯させて充電制御モードを終了する(S115)。   If the remaining capacity of the storage battery 3 detected by the capacity detection unit 51 is equal to or less than the minimum value VL (S110), it is determined that the amount of electric power that can light the illumination unit 4 cannot be secured in the storage battery 3, and the illumination unit 4 is The light is turned off (S115). When the turn-off time T2 is reached (S114), the illumination unit 4 is turned off and the charge control mode is terminated (S115).

ここで、図10及び図11を参照しながら、点灯/調光制御モードにおける調光制御の詳細について説明する。図10及び図11のタイミングチャートは、所定複数日(本実施例では3日間)の(a)調光パターンと(b)蓄電池3の残存容量の変化を模式的に示したものである。本実施例では、それぞれ平均照度が高い順に高照度L1、中照度L2及び低照度L3となる直線的なパターンを有する3つの調光パターンが設定されている。   Here, the details of the dimming control in the lighting / dimming control mode will be described with reference to FIGS. 10 and 11. The timing charts of FIGS. 10 and 11 schematically show changes in (a) dimming pattern and (b) remaining capacity of the storage battery 3 for a predetermined number of days (three days in this embodiment). In the present embodiment, three dimming patterns having a linear pattern of high illuminance L1, medium illuminance L2, and low illuminance L3 are set in descending order of average illuminance.

蓄電池3の残存容量の閾値(電力値)としては、満充電時の電力値VM、満充電より残存容量が低下した時の電力値としての第一閾値V1、第一閾値V1よりさらに残存容量が低下した時の電力値としての第二閾値V2、及び最低値VLが設定されている。そして、蓄電池3の残存容量に応じて、電力値VM〜第一閾値V1の間では高照度L1の調光パターンで調光し、第一閾値V1〜第二閾値V2の間では中照度L2の調光パターンで調光し、第二閾値V2〜最低値VLの間では低照度L3の調光パターンで調光する。各調光パターンにおける照度(高照度L1、中照度L2、低照度L3)は、広告看板として媒体価値を担保した基本性能を満たすように好ましく設定される。   As the threshold value (power value) of the remaining capacity of the storage battery 3, the remaining capacity is more than the power value VM at full charge, the first threshold value V1 as the power value when the remaining capacity is reduced from full charge, and the first threshold value V1. A second threshold value V2 and a minimum value VL are set as the power value when the voltage drops. And according to the remaining capacity of the storage battery 3, the light intensity is dimmed with the dimming pattern of the high illuminance L1 between the power value VM and the first threshold value V1, and the medium illuminance L2 is between the first threshold value V1 and the second threshold value V2. Dimming is performed using a dimming pattern, and dimming is performed using a dimming pattern with low illuminance L3 between the second threshold value V2 and the minimum value VL. The illuminance (high illuminance L1, medium illuminance L2, low illuminance L3) in each dimming pattern is preferably set so as to satisfy the basic performance assuring medium value as an advertising billboard.

図10に示すように、所定複数日(本実施例では3日間)において昼間の晴天(日照)が続き太陽電池パネル2にて充分な発電量が確保される場合には、日の出とともに蓄電池3の残存容量が満充電の電力値VMまで増加して回復する。そして、日の入り時刻(点灯時刻T1)になると、照明部4を点灯制御するとともに、蓄電池3の残存容量が電力値VM〜第一閾値V1の間にあるので高照度L1の調光パターンで調光制御する。かかる条件では、時間の経過とともに蓄電池3の残存容量は減少するが第一閾値V1以下になることはない。   As shown in FIG. 10, in the case where a clear amount of sunlight (sunshine) continues in the daytime for a predetermined number of days (three days in the present embodiment) and a sufficient amount of power generation is secured in the solar cell panel 2, The remaining capacity increases and recovers to the fully charged power value VM. When the sunset time (lighting time T1) is reached, the lighting unit 4 is controlled to be turned on, and the remaining capacity of the storage battery 3 is between the power value VM and the first threshold value V1, so that the light is adjusted with a light control pattern of high illuminance L1. Control. Under such conditions, the remaining capacity of the storage battery 3 decreases with the passage of time but does not fall below the first threshold value V1.

図11に示すように、所定複数日(本実施例では3日間)において昼間の悪天候(不日照)が続き太陽電池パネル2にて充分な発電量が確保されない場合には、日の出以降も蓄電池3への充電が行われず残存容量が増加しない。不日照1日目では、点灯時刻T1になり照明部4を点灯制御し、しばらくは蓄電池3の残存容量が第一閾値V1以上あるので高照度L1の調光パターンで調光制御するが、やがて蓄電池3の残存容量が第一閾値V1以下になると中照度L2の調光パターンに切り換える。   As shown in FIG. 11, in the case where bad weather (non-sunlight) continues in the daytime for a predetermined number of days (three days in the present embodiment) and a sufficient amount of power generation is not secured in the solar cell panel 2, the storage battery 3 even after sunrise. The battery is not charged and the remaining capacity does not increase. On the first day of non-sunshine, the lighting unit 4 is turned on at the lighting time T1, and the remaining capacity of the storage battery 3 is greater than or equal to the first threshold value V1, and the dimming control is performed with the dimming pattern of the high illuminance L1. When the remaining capacity of the storage battery 3 is equal to or less than the first threshold value V1, the dimming pattern is switched to the medium illuminance L2.

次いで、不日照2日目では、点灯時刻T1になり照明部4を点灯制御した後、しばらくは蓄電池3の残存容量が第二閾値V2以上あるので中照度L2の調光パターンで調光制御する。中照度L2の調光パターンは高照度L1の調光パターンよりも消費電力量は少ないが、それでも時間の経過とともに蓄電池3の残存容量が低下していき、やがて第二閾値V2以下になると低照度L2の調光パターンに切り換える。そして、不日照3日目では、点灯時刻T1になり照明部4を点灯制御した後、低照度L3の調光パターンで調光制御し、かかる条件では、不日照3日目の点灯時間ΔTの間は蓄電池3の残存容量は減少していくが第一閾値V1以下になることはないため、照明部4の点灯状態は維持される。   Next, on the second day of non-sunshine, after the lighting unit 4 is turned on at the lighting time T1, the remaining capacity of the storage battery 3 is greater than or equal to the second threshold value V2, and therefore the dimming control is performed with the dimming pattern of medium illuminance L2. . The dimming pattern with medium illuminance L2 consumes less power than the dimming pattern with high illuminance L1, but the remaining capacity of the storage battery 3 still decreases with the passage of time. Switch to L2 dimming pattern. On the third day of non-sunshine, the lighting unit 4 is turned on at the lighting time T1, and then dimming control is performed with a dimming pattern of low illuminance L3. Under such conditions, the lighting time ΔT of the third day of non-sunshine is In the meantime, the remaining capacity of the storage battery 3 decreases but does not become the first threshold value V1 or less, so that the lighting state of the illumination unit 4 is maintained.

このように本実施例では、不日照が3日間続いた場合であっても蓄電池3の残存容量に応じて調光パターンを可変させ、具体的には、蓄電池3の残存容量がVM→V1→V2と低下するにつれて調光パターンの照度をL1→L2→L3と下げて、照明部4での消費電力を低下させるように調光制御することで、所定複数日の点灯時間ΔTの間で照明部4の点灯状態を維持することができる。   As described above, in this embodiment, even when the non-sunlight continues for three days, the dimming pattern is varied according to the remaining capacity of the storage battery 3, and specifically, the remaining capacity of the storage battery 3 is VM → V1 → As the voltage decreases to V2, the illuminance of the dimming pattern is lowered from L1 to L2 to L3, and the dimming control is performed so as to reduce the power consumption in the illumination unit 4, thereby illuminating the lighting period ΔT for a predetermined number of days. The lighting state of the unit 4 can be maintained.

以上のように、本実施例の独立型内照式看板1は、LEDユニット41からの照射光によりFFシート42・42が内照される照明部4を具備してなる独立型内照式看板1において、太陽光エネルギーにより電力を出力する太陽電池パネル2と、太陽電池パネル2より出力された電力を充電する蓄電池3と、蓄電池3の放充電及び照明部4の照明状態を切り換える制御部5と、を具備してなり、制御部5は、予め設置環境に応じて設定された所定月日ごとの点灯時刻T1及び点灯時間ΔT並びに調光パターンに基づいて照明部4を点灯制御し、駆動時に蓄電池3の残存容量に応じて点灯時間ΔTの間で点灯維持可能な調光パターンに可変して照明部4を調光制御するものであるため、広告看板として媒体価値を担保した基本性能を満たしつつ、設置環境に応じて照明部の消費電力を制御して夜間に広告面を安定して点灯できるのである。   As described above, the stand-alone internally illuminated signboard 1 according to this embodiment includes the illumination unit 4 in which the FF sheets 42 and 42 are internally illuminated by the light emitted from the LED unit 41. 1, a solar cell panel 2 that outputs electric power by solar energy, a storage battery 3 that charges electric power output from the solar cell panel 2, and a control unit 5 that switches between discharging and charging the storage battery 3 and the illumination state of the illumination unit 4. The control unit 5 controls the lighting of the lighting unit 4 based on the lighting time T1 and the lighting time ΔT and the dimming pattern for each predetermined month set in advance according to the installation environment, and is driven. Since the lighting unit 4 is dimmed and controlled by changing to a dimming pattern that can be kept lit during the lighting time ΔT depending on the remaining capacity of the storage battery 3 at times, the basic performance that guarantees the medium value as an advertising signboard While satisfying By controlling the power consumption of the lighting unit according to the installation environment, the advertising surface can be lit stably at night.

すなわち、本実施例の独立型内照式看板1は、予め日射量、気候、気温、周辺照度などの設置環境の影響を予め考慮した点灯時刻T1及び点灯時間ΔTなどの照明条件を設定しておくことで、例えば、周囲の構造物等の影響を受けて日射量が異なったり、降水量や降雪量の違いにより日照時間が異なったり、周辺照度が明るい場所であれば照明効果が低減し、温度上昇により太陽電池パネル2の発電効率が低減したりするような外部の不確定要素に起因する照明条件のバラつきを低減することができるため、安定して独立型内照式看板1を駆動制御できるようになる。   That is, the stand-alone internally illuminated signboard 1 of the present embodiment is set in advance with lighting conditions such as lighting time T1 and lighting time ΔT in consideration of the influence of the installation environment such as the amount of solar radiation, climate, temperature, and ambient illuminance. For example, if the amount of solar radiation is different due to the influence of surrounding structures, etc., the sunshine time is different due to the difference in precipitation and snowfall, or the lighting effect is reduced if the surrounding illuminance is bright, Since it is possible to reduce variations in lighting conditions due to external uncertainties such as the power generation efficiency of the solar battery panel 2 being reduced due to temperature rise, the drive control of the stand-alone internally illuminated signboard 1 is stably performed. become able to.

このように設置環境に応じて所定月日ごとの点灯時刻T1等を設定するように構成することで、蓄電池3の残存容量を踏まえて広告看板として媒体価値を担保した基本性能を満たすような調光パターンの設定が可能となる。駆動時に蓄電池3の残存容量に応じて適切な調光パターンに切り換え可能となることで、特に、都市部や郊外に設置される大型の広告用看板として構成される場合であっても、太陽電池パネル2の発電量や蓄電池3の充電容量を物理的に増加させずに、照明部4の消費電力を制御して夜間に照明部4が突然消灯するのを防止して安定して点灯状態を維持でき、また、商用電源に依存しない独立型として(商用電源と接続できない)郊外などであっても簡易に設置することができる。   In this way, by configuring the lighting time T1 and the like for each predetermined month according to the installation environment, it is possible to satisfy the basic performance that guarantees the media value as an advertising signboard based on the remaining capacity of the storage battery 3. The light pattern can be set. By being able to switch to an appropriate dimming pattern according to the remaining capacity of the storage battery 3 during driving, the solar battery can be used even when it is configured as a large advertising billboard installed in an urban area or suburb. Without physically increasing the power generation amount of the panel 2 or the charging capacity of the storage battery 3, the power consumption of the lighting unit 4 is controlled to prevent the lighting unit 4 from suddenly turning off at night and to stably turn on the lighting. It can be maintained and can be easily installed as a stand-alone type that does not depend on a commercial power source (ie, cannot be connected to a commercial power source) even in the suburbs.

そして、本実施例の独立型内照式看板1のように、商用電源に依存しない独立電源型のLED内照式看板として構成することで、今後も継続的に実施される節電対策においても夜間の企業の事業活動や宣伝活動等の機会損失を解消することができ、また、広告を掲出する企業においても、事業・宣伝活動における節電対策の取組みとして社会への訴求も可能となり、いわば広告掲出がCSR活動の一環として評価されて企業のイメージアップに繋がる効果も期待できる。   And like the stand-alone internally illuminated signboard 1 of the present embodiment, it is constructed as an independent power supply type LED internally illuminated signboard that does not depend on the commercial power supply. Lost the opportunity loss of the business activities and advertising activities of other companies, and even companies that post advertisements can appeal to society as a measure to save electricity in their business and advertising activities. Can be expected to be effective as a part of CSR activities, leading to the improvement of corporate image.

特に、本実施例の独立型内照式看板1は、予め太陽電池パネル2の発電量に応じて点灯時刻T1及び点灯時間ΔT並びに調光パターンを設定するため、例えば、出力検知部50により検知された太陽電池パネル2の発電量(発電電力)より設置場所の日射量が少ないと判断した場合には、点灯時間ΔTを短くしたり調光パターンの照度Lを下げたりすることで、照明部4の消費電力をコントロールして、夜間に照明部4が突然消灯するのを効果的に防止して広告面を安定して点灯できる。   In particular, the stand-alone internally illuminated signboard 1 according to the present embodiment sets the lighting time T1, the lighting time ΔT, and the dimming pattern according to the power generation amount of the solar battery panel 2 in advance. If it is determined that the amount of solar radiation at the installation location is less than the generated power (generated power) of the solar cell panel 2, the lighting unit can be reduced by shortening the lighting time ΔT or decreasing the illuminance L of the dimming pattern By controlling the power consumption of 4, it is possible to effectively prevent the lighting unit 4 from suddenly turning off at night and to stably turn on the advertising surface.

また、本実施例の独立型内照式看板1は、設置場所別の所定月日ごとの照明情報に基づいて点灯時刻T1及び点灯時間ΔTを設定するため、点灯時刻T1や消灯時刻T2等の設定精度が高まり、外部の不確定要素に起因する照明条件のバラつきをより低減して、より安定して独立型内照式看板1を駆動制御できるようになる。   Moreover, since the stand-alone internally illuminated signboard 1 of this embodiment sets the lighting time T1 and the lighting time ΔT based on the illumination information for each predetermined month and day by installation location, the lighting time T1, the lighting time T2, etc. Setting accuracy is increased, and variations in illumination conditions caused by external uncertainties can be further reduced, and the stand-alone internally illuminated signboard 1 can be driven and controlled more stably.

また、本実施例の独立型内照式看板1は、制御部5にて、照明部4の照度を点灯時刻T1から所定時刻までの間は標準照度に対して上げ、所定時刻から消灯時刻T2までの間は標準照度に対して下げて調光制御するため、点灯時刻T1から所定時間の間は多くの対象者に対して効果的に照明機能を発揮できるとともに、対象者の数が減る消灯時刻T2近くの時間帯は照明部4による非効率な電力の消費を抑制できる。   Further, in the stand-alone internally illuminated signboard 1 of the present embodiment, the control unit 5 raises the illuminance of the illumination unit 4 with respect to the standard illuminance between the lighting time T1 and the predetermined time, and from the predetermined time to the turn-off time T2. Since the dimming control is performed by lowering the standard illuminance during the period until the lighting time T1, the lighting function can be effectively exhibited for many subjects from the lighting time T1 and the number of subjects is reduced. In the time zone near the time T2, inefficient power consumption by the illumination unit 4 can be suppressed.

また、本実施例の独立型内照式看板1は、制御部5にて、所定複数日あたりの点灯時間ΔTの間で点灯維持可能なように調光パターンを可変して調光制御するため、例えば、昼間の悪天候(不日照)が続くなどして太陽電池パネル2にて充分な発電量が確保されない場合であっても、少なくとも所定複数日の間は照明部4の点灯を維持することができるので、照明部4が不点灯の状態なったり、又は不点灯の状態が長期化したりするのを防止できる。   In addition, the independent interior-lit signboard 1 of the present embodiment performs dimming control by changing the dimming pattern so that the control unit 5 can maintain lighting during the lighting time ΔT per predetermined multiple days. For example, even when a sufficient amount of power generation is not secured in the solar cell panel 2 due to, for example, bad weather (non-sunshine) during the daytime, the lighting unit 4 should be kept on for at least a predetermined number of days. Therefore, it can prevent that the illumination part 4 becomes a non-lighting state or a non-lighting state prolongs.

また、本実施例の独立型内照式看板1は、制御部5にて、蓄電池3の残存容量が低下するにつれて照明部4の照度を下げるため、残存容量に対して照明部4の消費電力を効果的にコントロールして、照明部4が不点灯の状態なったり、又は不点灯の状態が長期化したりするのを効果的に防止できる。   Moreover, the stand-alone internally illuminated signboard 1 of the present embodiment lowers the illuminance of the illumination unit 4 as the remaining capacity of the storage battery 3 decreases in the control unit 5, so that the power consumption of the illumination unit 4 with respect to the remaining capacity. Can be effectively controlled to effectively prevent the lighting unit 4 from being unlit or from being unlit for a long time.

また、本実施例の独立型内照式看板1は、制御部5は、太陽電池パネル2の発電電力に応じて最大電力を得るように太陽電池パネル2の動作を制御する効率制御部52を有してなるため、太陽電池パネル2から効率よく出力電力を得ることができる。   Moreover, the stand-alone internally illuminated signboard 1 of the present embodiment includes an efficiency control unit 52 that controls the operation of the solar cell panel 2 so that the control unit 5 obtains the maximum power according to the generated power of the solar cell panel 2. Therefore, output power can be efficiently obtained from the solar cell panel 2.

Is possible.

すなわち、上述した実施例の独立型内照式看板1では、制御部5において、演算処理部55と効率制御部52等の他の制御回路とが別々に配置される構成について説明したが、制御部5の構成はこれに限定されず、例えば、演算処理部55のCPUと他の制御回路等を一体に構成してもよく、また、演算処理部55等がワンボードで構成されるだけでなく、例えば、MPPT制御装置として効率制御部52と専用の演算処理部とを組み付けて別体で構成してもよい。   That is, in the stand-alone internally illuminated signboard 1 of the above-described embodiment, the control unit 5 has been described with respect to the configuration in which the arithmetic processing unit 55 and other control circuits such as the efficiency control unit 52 are separately arranged. The configuration of the unit 5 is not limited to this. For example, the CPU of the arithmetic processing unit 55 may be configured integrally with another control circuit, or the arithmetic processing unit 55 may be configured as a single board. For example, the efficiency control unit 52 and a dedicated arithmetic processing unit may be assembled as a separate MPPT control device.

また、上述した実施例の独立型内照式看板1では、制御部5において、1年間の月日ごとに点灯時刻T1及び点灯時間ΔTを設定するものであるが、予め設定する点灯時刻T1等としては所定月日ごとに設定すればよく、例えば、複数日ごと(例えば1週間や1ケ月ごと)に設定してもよい。   Moreover, in the stand-alone internally illuminated signboard 1 of the above-described embodiment, the control unit 5 sets the lighting time T1 and the lighting time ΔT for each year of the year. May be set every predetermined month, for example, may be set every plural days (for example, every week or every month).

また、上述した実施例の独立型内照式看板1では、設置場所設定部55bにて設置場所の選択操作が行わることで所定の設置場所に対応した照明情報が選択されるものであるが、必ずしも設置場所設定部55bを設ける必要はなく、例えば、入出力用機器6等を介してより詳細な設置場所を選択して個別の照明情報を選択するようにしてもよい。   In addition, in the independent interior-lit signboard 1 of the above-described embodiment, the illumination information corresponding to a predetermined installation location is selected by performing an installation location selection operation in the installation location setting unit 55b. However, it is not always necessary to provide the installation location setting unit 55b. For example, a more detailed installation location may be selected via the input / output device 6 or the like to select individual illumination information.

また、上述した実施例の独立型内照式看板1では、消灯時刻T2を一律に設定して、かかる消灯時刻T2と点灯時刻T1とを差分して点灯時間ΔTを演算するようにしているが、内照式看板として構成した場合であっても、消灯時刻T2を一律に設定することなく日の出時刻に基づいて演算して、例えば、夜間は日の出時刻まで点灯状態を維持するようにしたり、所定時間経過後は消灯しつつ対物センサ等により人体等が接近した場合にのみ点灯したりするようにしてもよい。   Moreover, in the stand-alone internally illuminated signboard 1 of the above-described embodiment, the turn-off time T2 is set uniformly, and the turn-on time T is calculated by subtracting the turn-off time T2 and the turn-on time T1. Even if it is configured as an internally illuminated signboard, it is calculated based on the sunrise time without setting the turn-off time T2 uniformly, for example, the lighting state is maintained until the sunrise time at night, It may be turned on only when a human body or the like approaches by an objective sensor or the like while the light is turned off after the elapse of time.

また、上述した実施例の独立型内照式看板1では、調光パターンとして、図7に示したように直線状又は非直線状のパターンとしているが、調光パターンはこれらに限定されず、曲線的に照度を増減するようにしてもよく、また標準照度Lに対する照度の増減量やタイミングなどを適宜設定できるようにしてもよい。さらに、予め複数の調光パターンを設定しておく他に、蓄電池3の残存容量と照明部4の消費電力との相関関係をフィードバックして新たな調光パターンを適時生成するようにしてもよい。   In addition, in the above-mentioned independent internal signboard 1 of the embodiment, as the dimming pattern, it is a linear or non-linear pattern as shown in FIG. 7, but the dimming pattern is not limited to these, The illuminance may be increased / decreased in a curve, or the illuminance increase / decrease amount with respect to the standard illuminance L, the timing, and the like may be appropriately set. Further, in addition to setting a plurality of dimming patterns in advance, a new dimming pattern may be generated in a timely manner by feeding back the correlation between the remaining capacity of the storage battery 3 and the power consumption of the illumination unit 4. .
