充放電制御装置10は、制御部11の制御に基づき、照度計16を用いて後述する内照明式看板1の周囲の照度を測定して該照度に応じて光源14に供給される駆動電力の値が決定される。この様な充放電制御装置10は、図1に示すように、制御部11、太陽電池12、バッテリ13、光源14、リレー15、及び照度計16から構成される。以下、充放電制御装置10を構成する各構成部材について説明する。 The charge / discharge control device 10 measures the illuminance around the internal lighting type signboard 1 to be described later using the illuminance meter 16 based on the control of the control unit 11, and determines the driving power supplied to the light source 14 according to the illuminance. The value is determined. As shown in FIG. 1, such a charge / discharge control device 10 includes a control unit 11, a solar cell 12, a battery 13, a light source 14, a relay 15, and an illuminometer 16. Hereinafter, each structural member which comprises the charging / discharging control apparatus 10 is demonstrated.
充放電制御装置10を構成する制御部11は、制御手段であり、具体的には照度計16を用いて内照明式看板1の周囲の照度を測定して該照度に応じて光源14に供給する駆動電力の値を決定する。具体的には、制御部11の制御に基づき、複数備えられたバッテリ13から、内照明式看板1の周囲の照度が高い場合に充電率の高いバッテリ13が選択され、且つ内照明式看板1の周囲の照度が低い場合に充電率の低いバッテリ13が選択され、後述する内照明式看板1に設けられた光源14に駆動電力が供給される。また、制御部11の制御に基づき、複数備えられたバッテリ13から充電率の低いバッテリ13を順に選択して太陽電池12により発電された電力が充電される。ここで充電率は、満充電を100%としたときの割合を現している。この様な制御部11は、制御プログラムを格納したROM、制御プログラムに基づいて充放電制御装置10を制御するCPU、複数設けられたバッテリ13の充電率や照度計16で測定した内照明式看板1の周囲の照度等を記憶するRAM、複数設けられたバッテリ13の充電率を比較するコンパレータ、各制御のタイミングを所定の周期で計測するタイマーカウンタ、及び内照明式看板1を一定の時間帯に点灯させる場合に用いる時計等から構成される。また、制御部11に、太陽電池12での発電電力を経時的に計測する計数カウンタを設けても良い。 The control part 11 which comprises the charging / discharging control apparatus 10 is a control means, Specifically, the illumination intensity around the internal illumination type | mold signboard 1 is measured using the illumination meter 16, and it supplies to the light source 14 according to this illumination intensity The drive power value to be determined is determined. Specifically, based on the control of the control unit 11, the battery 13 having a high charging rate is selected from the plurality of batteries 13 when the illuminance around the internal lighting sign 1 is high, and the internal lighting sign 1 When the illuminance around is low, the battery 13 having a low charging rate is selected, and driving power is supplied to the light source 14 provided in the internal lighting sign 1 described later. Moreover, based on control of the control part 11, the battery 13 with a low charging rate is selected in order from the battery 13 provided, and the electric power generated by the solar cell 12 is charged. Here, the charging rate represents the ratio when the full charge is 100%. Such a control unit 11 includes a ROM that stores a control program, a CPU that controls the charge / discharge control device 10 based on the control program, a charging rate of a plurality of batteries 13 and an internally illuminated signboard measured by an illuminometer 16. RAM for storing the illuminance and the like around 1, a comparator for comparing the charging rates of a plurality of batteries 13, a timer counter for measuring the timing of each control at a predetermined period, and the internal illumination type signboard 1 in a certain time zone It is comprised from the timepiece etc. which are used when making it light. Further, the control unit 11 may be provided with a counter that measures the power generated by the solar battery 12 over time.
充放電制御装置10を構成する太陽電池12は、太陽光等がpn接合型ダイオード等に照射されたときに生じる光電効果により、太陽光等の光エネルギから電力を生成する発電素子である。この様な太陽電池12は、例えばシリコン半導体から形成されたものを用いる。また、太陽電池12は、必要とされる電圧値と電流値に基づいて、例えば図2に示すように直列又は並列に複数個接続して使用する。また、太陽電池12は、内照明式看板1を設置する環境等に応じて、紫外光と可視光領域で透明性を有するガラス等により被覆して保護する。なお、太陽電池12は、光エネルギを電力に変換するものの蓄電機能を有さないことから、制御部11の制御に基づき、発電した電力を後述するバッテリ13に充電する。 The solar cell 12 constituting the charge / discharge control device 10 is a power generation element that generates electric power from light energy such as sunlight by a photoelectric effect generated when sunlight or the like is irradiated onto a pn junction diode or the like. Such a solar cell 12 is made of, for example, a silicon semiconductor. Further, for example, a plurality of solar cells 12 are connected in series or in parallel as shown in FIG. 2 based on the required voltage value and current value. Moreover, the solar cell 12 is covered and protected by glass or the like having transparency in the ultraviolet light and visible light regions according to the environment or the like in which the internal illumination signboard 1 is installed. In addition, since the solar cell 12 converts light energy into electric power but does not have a power storage function, the battery 13 described later is charged with generated electric power based on the control of the control unit 11.
充放電制御装置10を構成する複数のバッテリ13は、太陽電池12で発電した電力を充電する蓄電池である。この様なバッテリ13には、例えば鉛電池、リチウムイオン電池、又はスーパーキャパシタを用いた電池を用いることができる。なお、鉛電池は、例えば正極板に二酸化鉛、負極板に海綿状鉛、及び電解液に希硫酸が用いられている。該鉛電池は鉛と硫酸の化学反応により充放電を行う。また、リチウムイオン電池は、例えば正極にコバルト酸リチウム、負極にカーボンが用いられている。該リチウムイオン電池は、Liイオンが正極と負極との間を往復することにより充放電を行う。また、スーパーキャパシタを用いた電池は、電気二重層を形成する固体と液体との界面に正負の電荷が蓄えられる現象を用いた電池である。なお、複数のバッテリ13には、それぞれ図示せぬ電圧計及び電流計が備えられ、制御部11から個々のバッテリ13の電圧値及び電流値を読み出し、個々のバッテリ13の充電率を算出するように構成されている。 The plurality of batteries 13 constituting the charge / discharge control device 10 are storage batteries that charge the power generated by the solar battery 12. As such a battery 13, for example, a lead battery, a lithium ion battery, or a battery using a super capacitor can be used. In the lead battery, for example, lead dioxide is used for the positive electrode plate, spongy lead is used for the negative electrode plate, and dilute sulfuric acid is used for the electrolytic solution. The lead battery is charged and discharged by a chemical reaction between lead and sulfuric acid. Further, in the lithium ion battery, for example, lithium cobaltate is used for the positive electrode and carbon is used for the negative electrode. The lithium ion battery is charged and discharged by reciprocating Li ions between the positive electrode and the negative electrode. A battery using a supercapacitor is a battery using a phenomenon in which positive and negative charges are stored at the interface between a solid and a liquid forming an electric double layer. The plurality of batteries 13 are each provided with a voltmeter and an ammeter (not shown), and the voltage value and current value of each battery 13 are read from the control unit 11 to calculate the charging rate of each battery 13. It is configured.
充放電制御装置10を構成する光源14は、発光手段であり、具体的には後述する内照明式看板1に設けられた導光板20の端面から光を入射させ導光板20の主面に形成された凹面で拡散光を発生させるための光源である。この様な光源14は、導光板20の端面の形状に沿うように棒状に形成されたガラエポ基板等に複数個の白色LEDを配設することにより構成される。ここで、光源14に配設された白色LEDに駆動電流を印加して白色LED光を導光板20の端面に入射させると、該白色LED光が導光板20の主面である表面や裏面に形成された凹部に照射されることにより、各凹部で拡散光が発生する。 The light source 14 constituting the charge / discharge control device 10 is a light emitting means, and specifically, is formed on the main surface of the light guide plate 20 by allowing light to enter from the end surface of the light guide plate 20 provided in the internal illumination signboard 1 to be described later. This is a light source for generating diffused light on the concave surface. Such a light source 14 is configured by arranging a plurality of white LEDs on a glass epoxy substrate or the like formed in a rod shape so as to follow the shape of the end face of the light guide plate 20. Here, when a driving current is applied to the white LED disposed in the light source 14 to cause the white LED light to enter the end face of the light guide plate 20, the white LED light is applied to the front surface and the back surface that are the main surface of the light guide plate 20. By irradiating the formed recess, diffused light is generated in each recess.
充放電制御装置10を構成するリレー15は、選択手段であり、具体的には充放電制御装置10に複数備えられたバッテリ13において、個々のバッテリ13毎に太陽電池12からの電力の供給をON又はOFFするスイッチである。この様なリレー15は、例えば電気信号を受けて機械的な動きに変える電磁石と開閉スイッチから成る。具体的には、リレー15は、制御部11の制御に基づき充放電制御装置10に複数備えられたバッテリ13の中で充電率の低いバッテリ13が選択された時に、該選択されたバッテリ13には太陽電池12で発電された電力を供給し、選択されていないバッテリ13には太陽電池12で発電された電力を供給しない様に、電力の供給をON又はOFFする。同様に、リレー15は、充放電制御装置10に複数備えられたバッテリ13において、個々のバッテリ13毎に光源14への駆動電力の供給をON又はOFFするスイッチである。 The relays 15 constituting the charge / discharge control device 10 are selection means. Specifically, in the batteries 13 provided in the charge / discharge control device 10, power is supplied from the solar cells 12 for each individual battery 13. It is a switch that turns on or off. Such a relay 15 includes, for example, an electromagnet that changes into a mechanical movement in response to an electric signal and an open / close switch. Specifically, when the battery 13 having a low charging rate is selected from among a plurality of batteries 13 provided in the charge / discharge control device 10 based on the control of the control unit 11, the relay 15 is connected to the selected battery 13. Supplies the power generated by the solar cell 12 and turns on or off the power supply so that the battery 13 not selected is not supplied with the power generated by the solar cell 12. Similarly, the relay 15 is a switch that turns on or off the supply of drive power to the light source 14 for each battery 13 in the plurality of batteries 13 provided in the charge / discharge control device 10.
充放電制御装置10を構成する照度計16は、内照明式看板1の周囲の照度を測定する照度計である。この様な照度計16は、例えば太陽から照射される光の波長領域に感度を有するSiフォトダイオードと、該Siフォトダイオードを被覆して保護する紫外光と可視光領域で透明性を有するガラス等から構成される。ここで、照度計16により測定された内照明式看板1の周囲の照度の値に基づいて、バッテリ13から光源14に供給される駆動電力の値が決定される。具体的には、例えば日中やネオン灯や街灯などの近くに設置された内照明式看板1の周囲の照度は高く測定されることから、内照明式看板1が該ネオン灯や街灯の明るさに埋没しないように光源14に供給される駆動電力の値が高く設定される。また、早朝や夜間及び街灯等が無く比較的暗い場所などに設置された内照明式看板1の周囲の照度は低く測定されることから、内照明式看板1が多少暗くても識別可能であることから光源14に供給される駆動電力の値が低く設定される。なお、上述した照度計16の機能を、太陽電池12による発電電力を制御部11に設けられた計数カウンタで計測する構成で代用させても良い。この様な場合には、太陽電池12による発電電力が高い程、照度が高いと規定する。 The illuminance meter 16 constituting the charge / discharge control device 10 is an illuminance meter that measures the illuminance around the internal illumination signboard 1. Such an illuminometer 16 includes, for example, a Si photodiode having sensitivity in the wavelength region of light irradiated from the sun, and glass having transparency in the ultraviolet and visible light regions that cover and protect the Si photodiode. Consists of Here, the value of the driving power supplied from the battery 13 to the light source 14 is determined based on the value of the illuminance around the internal lighting type signboard 1 measured by the illuminometer 16. Specifically, for example, since the illuminance around the internally illuminated signboard 1 installed near the daytime or in the vicinity of a neon lamp, streetlight, etc. is measured, the interior illuminated signboard 1 is brightened by the neon lamp or streetlight. The value of the driving power supplied to the light source 14 is set high so as not to be buried. In addition, since the illuminance around the internally illuminated signboard 1 installed in a relatively dark place without an early morning, nighttime, or street light is measured, it can be identified even if the internally illuminated signboard 1 is somewhat dark. Therefore, the value of the driving power supplied to the light source 14 is set low. The function of the illuminometer 16 described above may be replaced by a configuration in which the power generated by the solar battery 12 is measured by a counter counter provided in the control unit 11. In such a case, the higher the power generated by the solar cell 12, the higher the illuminance.
次に、充放電制御装置10が設けられた内照明式看板1の構成、仕様、及び動作等について、図2及び図3を参照しながら具体的に説明する。 Next, the configuration, specifications, operation, and the like of the internal illumination signboard 1 provided with the charge / discharge control device 10 will be specifically described with reference to FIGS. 2 and 3.
内照明式看板1は、該内照明式看板1に配設した充放電制御装置10により、安定した電力で且つ内照明式看板1の周囲の照度に対応した照度で、広告パネル30を発光させることができる。この様な内照明式看板1は、前述した充放電制御装置10、主面に形成された凹部で発生させた拡散光により後述する広告パネル30を背面から照らす導光板20、導光板20から照らされた光により例えば会社名からなる情報を伝達する広告パネル30、各構成部材を固定する筐体40、及び筐体40を支持する支柱50から構成される。以下、内照明式看板1を構成する各構成部材について説明する。但し、充放電制御装置10については、図1を参照しながら前述したことから説明を省く。 The interior lighting signboard 1 causes the advertising panel 30 to emit light with stable power and illuminance corresponding to the illuminance around the interior lighting signboard 1 by the charge / discharge control device 10 disposed in the interior lighting signboard 1. be able to. Such an internal illumination type signboard 1 is illuminated from the charge / discharge control device 10 described above, a light guide plate 20 that illuminates an advertising panel 30 to be described later from the back by diffused light generated in a recess formed on the main surface, and light from the light guide plate 20. For example, it is composed of an advertising panel 30 that transmits information including a company name by the emitted light, a housing 40 that fixes each component, and a column 50 that supports the housing 40. Hereinafter, each structural member which comprises the internal illumination type | mold signboard 1 is demonstrated. However, the description of the charge / discharge control device 10 will be omitted because it has been described above with reference to FIG.
内照明式看板1を構成する導光板20は、該導光板20の主面に形成された凹部で発生させた拡散光により後述する広告パネル30を背面から照らすバックライトである。この様な導光板20は、例えばメタクリル樹脂(Polymethylmethacrylate)板から成り、広告パネル30の主面に隣接して設けられるように所定の板状部から形成され、該板状部には複数の凹部が超音波加工等により設けられている。具体的には、該凹部は、板状部から形成される導光板20の主面に対して、例えば長径0.6mm及び深さ0.4mmの四角錐形状痕から形成され、例えば2.0mmの間隔でマトリクス状に設けられている。なお、導光板20は、後述する筐体40の上部板41と光源14にそれぞれ係合した状態で固定される。また、上述した導光板20に、例えば会社名からなる広告情報を直接印刷して表示させても良い。 The light guide plate 20 constituting the internal lighting type signboard 1 is a backlight that illuminates an advertisement panel 30 (to be described later) from the back by diffused light generated in a recess formed in the main surface of the light guide plate 20.

最後に、充放電制御装置10により周囲の照度に応じて内照明式看板1を点灯及び消灯させる制御について、図4及び図5を参照しながら説明する。 Finally, control for turning on and off the internal lighting type signboard 1 according to the ambient illuminance by the charge / discharge control device 10 will be described with reference to FIGS. 4 and 5.
内照明式看板1を点灯及び消灯させる制御について、まず図4を参照しながら説明する。図4には、充放電制御装置10により周囲の照度に応じて内照明式看板1を点灯及び消灯させる制御を、横軸に朝昼晩の一日に亘る時間を取り且つ図4(a)の縦軸には内照明式看板1の周囲の照度を取り、図4(b)の縦軸には内照明式看板1に設けられた光源14の駆動電力を取ることにより、模式図で示している。以下、内照明式看板1を点灯及び消灯させる制御に関し、図4(a)及び(b)の横軸において朝を示す左端から夜を示す右端にかけて順に説明する。 Control for turning on and off the internal lighting type signboard 1 will be described first with reference to FIG. In FIG. 4, the control for turning on and off the internal lighting type signboard 1 according to the ambient illuminance by the charge / discharge control device 10 takes time for one day in the morning, day and night on the horizontal axis, and FIG. The vertical axis of Fig. 4 shows the illuminance around the internally illuminated signboard 1, and the vertical axis of Fig. 4B shows the schematic diagram by taking the driving power of the light source 14 provided in the internally illuminated signboard 1. ing. Hereinafter, the control for turning on and off the internal lighting type signboard 1 will be described in order from the left end indicating morning to the right end indicating night on the horizontal axis of FIGS. 4 (a) and 4 (b).
図4の横軸に係るt0乃至t1直前の時間帯は、季節より異なるが例えば早朝から日の出過ぎまでを示しており、内照明式看板1の周囲が日中に比べて相対的に暗い。このため、照度計16で測定した内照明式看板1の周囲の照度は、図4(a)の右側の縦軸に示す所定の照度値である閾値1を下回っている。なお、該閾値1の値は、予め所定の値に設定しておく。この様に図4の横軸に係るt0乃至t1直前の時間帯は、内照明式看板1の周囲も相対的に暗いことから、内照明式看板1が多少暗くても広告パネル30を識別することができる。そこで、制御部11の制御に基づき、図4(b)の右側の縦軸に示すように複数のバッテリ13の中から充電率が低いバッテリ13を選択して、光源14を相対的に低い駆動電力で発光させる。なお、図4(b)の右側の縦軸では上記の様に充電率が低いバッテリ13をバッテリ弱と規定する。 The time period immediately before t0 to t1 on the horizontal axis in FIG. 4 is different from the season, but shows, for example, from early morning to over sunrise, and the surroundings of the internally illuminated signboard 1 are relatively dark compared to the daytime. For this reason, the illuminance around the internal illumination type signboard 1 measured by the illuminance meter 16 is lower than the threshold value 1 which is a predetermined illuminance value indicated on the vertical axis on the right side of FIG. The threshold value 1 is set to a predetermined value in advance. As described above, in the time zone immediately before t0 to t1 on the horizontal axis in FIG. 4, the surroundings of the internally illuminated signboard 1 are also relatively dark, so that the advertisement panel 30 is identified even if the internally illuminated signboard 1 is somewhat dark. be able to. Therefore, based on the control of the control unit 11, a battery 13 having a low charging rate is selected from a plurality of batteries 13 as shown on the right vertical axis in FIG. It emits light with electric power. In addition, in the right vertical axis | shaft of FIG.4 (b), the battery 13 with a low charging rate is prescribed | regulated as a battery weak as mentioned above.
図4の横軸に係るt1乃至t2直前の時間帯は、天候にもよるが一日の中で照度が最も高くなる日中を示しており、内照明式看板1の周囲が朝や夜に比べて相対的に非常に明るい。このため、照度計16で測定した内照明式看板1の周囲の照度は、図4(a)の右側の縦軸に示す所定の照度値である閾値1を上回っている。この様に図4の横軸に係るt1乃至t2直前の時間帯は、内照明式看板1の周囲が相対的に非常に明るいことから、内照明式看板1の広告パネル30を発光しても該広告パネル30の識別力には影響が少ない。そこで、制御部11の制御に基づき、図4(b)に示すように光源14への駆動電力の供給が停止される。 The time zone immediately before t1 to t2 on the horizontal axis in FIG. 4 shows the daytime when the illuminance is highest during the day, although it depends on the weather. It is relatively very bright. For this reason, the illuminance around the internal illumination signboard 1 measured by the illuminance meter 16 exceeds the threshold value 1, which is a predetermined illuminance value shown on the right vertical axis of FIG. In this way, in the time zone immediately before t1 to t2 on the horizontal axis in FIG. 4, the surroundings of the internal illumination signboard 1 are relatively bright, so even if the advertising panel 30 of the internal illumination signboard 1 emits light. There is little influence on the discrimination power of the advertisement panel 30. Therefore, based on the control of the control unit 11, the supply of driving power to the light source 14 is stopped as shown in FIG.
図4の横軸に係るt2乃至t3直前の時間帯は、季節より異なるが例えば正午過ぎから夕方までを示しており、内照明式看板1の周囲が日中に比べて若干暗い。このため、照度計16で測定した内照明式看板1の周囲の照度は、図4(a)の右側の縦軸に示す所定の照度値である閾値1を下回っている。しかしながら、図4の横軸に係るt2乃至t3直前の時間帯は、該内照明式看板1の周囲はまだ相当明るいことから、内照明式看板1の広告パネル30を強く発光させることにより該広告パネル30を識別できるようにする。そこで、制御部11の制御に基づき、図4(b)の右側の縦軸に示すように複数のバッテリ13の中から充電率が高いバッテリ13を選択して、光源14を相対的に高い駆動電力で発光させる。なお、図4(b)の右側の縦軸では上記の様に充電率が高いバッテリ13をバッテリ強と規定する。 The time period immediately before t2 to t3 on the horizontal axis in FIG. 4 is different from the season, but shows, for example, from noon to the evening, and the surroundings of the internally illuminated signboard 1 are slightly darker than during the daytime. For this reason, the illuminance around the internal illumination type signboard 1 measured by the illuminance meter 16 is lower than the threshold value 1 which is a predetermined illuminance value indicated on the vertical axis on the right side of FIG. However, in the time zone immediately before t2 to t3 on the horizontal axis in FIG. 4, the surroundings of the inner-lighted signboard 1 are still quite bright, so that the advertisement panel 30 of the inner-lighted signboard 1 is made to emit light strongly. The panel 30 can be identified. Therefore, based on the control of the control unit 11, a battery 13 having a high charging rate is selected from a plurality of batteries 13 as shown on the right vertical axis in FIG. 4B, and the light source 14 is driven relatively high. It emits light with electric power. In the right vertical axis in FIG. 4B, the battery 13 having a high charging rate as described above is defined as battery strength.
図4(a)の横軸に係るt3乃至t4直前の時間帯は、季節より異なるが例えば夕方から日の入り直前までを示しており、内照明式看板1の周囲が日中に比べて相当暗い。このため、照度計16で測定した内照明式看板1の周囲の照度は、図4(a)の右側の縦軸に示す所定の照度値である閾値2を下回っている。なお、照度は閾値1よりも閾値2の方が低い。また、図4の横軸に係るt3乃至t4直前の時間帯は、内照明式看板1の周囲が相当暗いため、内照明式看板1の広告パネル30を強く発光させなくても該広告パネル30を識別させることができる。そこで、制御部11の制御に基づき、図4(b)の右側の縦軸に示すように複数のバッテリ13の中から充電率が平均値のバッテリ13を選択して、光源14を発光させる。なお、図4(b)の右側の縦軸では上記の様に充電率が平均値のバッテリ13をバッテリ中と規定する。 The time period immediately before t3 to t4 on the horizontal axis in FIG. 4A is different from the season, but shows, for example, from evening to just before sunset, and the surroundings of the internally illuminated signboard 1 are considerably darker than during the daytime. For this reason, the illuminance around the internal illumination type signboard 1 measured by the illuminance meter 16 is below the threshold value 2 which is a predetermined illuminance value shown on the vertical axis on the right side of FIG. Note that the illuminance is lower at the threshold value 2 than at the threshold value 1. In addition, during the time period immediately before t3 to t4 on the horizontal axis in FIG. 4, the surroundings of the interior lighting signboard 1 are considerably dark, so that the advertisement panel 30 of the interior lighting signboard 1 does not emit light strongly. Can be identified. Therefore, based on the control of the control unit 11, the battery 13 having an average charging rate is selected from the plurality of batteries 13 as shown on the vertical axis on the right side of FIG. Note that the vertical axis on the right side of FIG. 4B defines the battery 13 having an average charging rate as described above as being in the battery.
図4の横軸に係るt4乃至t5の時間帯は、季節より異なるが例えば日の入り後から深夜までを示しており、内照明式看板1の周囲が日中に比べてかなり暗い。このため、照度計16で測定した内照明式看板1の周囲の照度は、図4(a)の右側の縦軸に示す所定の照度値である閾値3を下回っている。なお、照度は閾値2よりも閾値3の方が低い。また、図4の横軸に係るt4乃至t5の時間帯は、内照明式看板1の周囲がかなり暗いことから、内照明式看板1の広告パネル30が多少暗くても該広告パネル30を識別させることができる。そこで、制御部11の制御に基づき、図4(b)の右側の縦軸に示すように複数のバッテリ13の中から充電率が低い弱のバッテリ13を選択して、光源14を発光させる。なお、図4(b)の右側の縦軸では上記の様に充電率が低いバッテリ13をバッテリ弱と規定する。 The time period from t4 to t5 on the horizontal axis in FIG. 4 is different from the season, but shows, for example, after sunset, until midnight, and the surroundings of the internally illuminated signboard 1 are considerably darker than during the daytime. For this reason, the illuminance around the internal illumination type signboard 1 measured by the illuminance meter 16 is lower than the threshold value 3, which is a predetermined illuminance value shown on the right vertical axis of FIG. Note that the illuminance is lower at the threshold 3 than at the threshold 2. Also, during the period from t4 to t5 on the horizontal axis in FIG. 4, since the surroundings of the internally illuminated signboard 1 are considerably dark, the advertisement panel 30 is identified even if the advertisement panel 30 of the internally illuminated signboard 1 is somewhat dark. Can be made. Therefore, based on the control of the control unit 11, a weak battery 13 having a low charging rate is selected from the plurality of batteries 13 as shown on the vertical axis on the right side of FIG. In addition, in the right vertical axis | shaft of FIG.4 (b), the battery 13 with a low charging rate is prescribed | regulated as a battery weak as mentioned above.
図4の横軸に係るt0乃至t5の時間帯毎に場合分けて説明した通り、内照明式看板1において、制御部11の制御に基づき、内照明式看板1の周囲の照度が高い場合に複数備えられたバッテリ13の中から充電率の高いバッテリ13を選択し、且つ内照明式看板1の周囲の照度が低い場合に充電率の低いバッテリ13を選択する。なお、図4の横軸に係るt0乃至t5の時間帯において、充放電制御装置10は、制御部11の制御に基づき、複数備えられたバッテリ13から充電率の低いバッテリ13を順に選択して太陽電池12により発電された電力を充電させる。なお、図5(a)及び(b)は、図4(a)及び(b)と比較して、横軸t2、t3、及びt4の時間帯における内照明式看板1の周囲の照度の低下が著しい場合を示したものであり、バッテリ13の選択方法や光源14の駆動方法については図4を参照しながら前述した方法と同様である。 As described in each case for each of the time periods from t0 to t5 on the horizontal axis in FIG. 4, when the illuminance around the interior illumination signboard 1 is high in the interior illumination signboard 1 based on the control of the control unit 11. A battery 13 with a high charging rate is selected from among a plurality of batteries 13, and a battery 13 with a low charging rate is selected when the illuminance around the internally illuminated signboard 1 is low. In the time period from t0 to t5 on the horizontal axis in FIG. 4, the charge / discharge control device 10 selects a plurality of batteries 13 having a low charging rate from a plurality of batteries 13 based on the control of the control unit 11. The electric power generated by the solar battery 12 is charged. 5 (a) and 5 (b) show a decrease in illuminance around the internally illuminated signboard 1 in the time periods of the horizontal axes t2, t3, and t4, compared to FIGS. 4 (a) and 4 (b). The method for selecting the battery 13 and the method for driving the light source 14 are the same as those described above with reference to FIG.
また、全てのバッテリ13の充電の状態が良好の場合には、充電率の低いバッテリ13から順に太陽電池12から充電を行い、且つ充電率の高いバッテリ13から順に光源14に駆動電力を供給する制御を行っても良い。また、複数のバッテリ13の全ての充電が不十分である場合には、光源14の駆動電圧を十分に下げた状態で、例えば19時乃至24時迄の間のみ光源14を駆動する時間帯制御を行っても良い。また、複数のバッテリ13を並列に接続しておき、バッテリ13を複数個同時に並列で使用することによって冬季等の日照時間の少ない時に、個々のバッテリ13の使用量を均等に抑制する構成としても良い。なお、バッテリ13への充電が行えない等の不良が発生した場合には、制御部11を介して、内照明式看板1上で図示せぬ表示ランプを点滅させるなどにより報知する構成としても良い。 When all the batteries 13 are in a good charge state, the battery 13 is charged in order from the battery 13 with the lowest charge rate, and the driving power is supplied to the light source 14 in order from the battery 13 with the higher charge rate. Control may be performed. Further, when all of the plurality of batteries 13 are not sufficiently charged, time zone control for driving the light source 14 only from 19:00 to 24:00, for example, with the drive voltage of the light source 14 sufficiently lowered. May be performed. In addition, by connecting a plurality of batteries 13 in parallel and using a plurality of batteries 13 in parallel at the same time, the amount of use of each battery 13 can be evenly suppressed when the sunshine hours are low, such as in winter. good. It should be noted that when a failure such as inability to charge the battery 13 occurs, a notification may be made by blinking a display lamp (not shown) on the internal lighting type sign 1 via the control unit 11. .
以上、充放電制御装置10を設けた内照明式看板1によれば、制御部11の制御に基づき、内照明式看板1の周囲の照度が高い場合には複数備えられたバッテリ13から充電率の高いバッテリ13を選択して高い駆動電圧で光源14を相対的に強く発光させ、内照明式看板1の周囲の照度が低い場合には複数備えられたバッテリ13から充電率の低いバッテリ13を選択して低い駆動電圧で光源14を相対的に弱く発光させる。したがって、発電される電力量が天候に左右される太陽電池12から複数のバッテリ13に充電しても、個々のバッテリ13の充電状態に応じて光源14に対して均等に駆動電力を供給することにより、全てのバッテリ13の寿命を延ばすことができる。また、内照明式看板1の周囲の照度に応じて内照明式看板1に設けた広告パネル30を適切に発光させることで、内照明式看板1を目視した人に対して時間帯や天候に寄らず十分に情報を伝達することができる。 As described above, according to the internal illumination signboard 1 provided with the charge / discharge control device 10, based on the control of the control unit 11, when the illuminance around the internal illumination signboard 1 is high, the charging rate from the plurality of batteries 13 provided. Battery 13 having a low charging rate is selected from a plurality of batteries 13 when the light source 14 is selected to emit light relatively strongly with a high drive voltage and the illuminance around the internally illuminated sign 1 is low. The light source 14 is made to emit light relatively weakly with a low driving voltage. Accordingly, even when the plurality of batteries 13 are charged from the solar battery 12 whose amount of generated power depends on the weather, the driving power is evenly supplied to the light source 14 according to the charging state of each battery 13. Thus, the lifetime of all the batteries 13 can be extended. Further, by appropriately causing the advertising panel 30 provided on the internal illumination signboard 1 to emit light according to the illuminance around the internal illumination signboard 1, it is possible to adjust the time zone and the weather to the person who viewed the internal illumination signboard 1 It is possible to communicate information without stopping.
また、充放電制御装置10を設けた内照明式看板1によれば、制御部11の制御に基づき、複数備えられたバッテリ13から充電率の低いバッテリ13から順に選択して太陽電池12により発電された電力が充電される。したがって、発電される電力量が天候に左右される太陽電池12でも複数のバッテリ13を効率良く充電することができ、バッテリ13の充電が不足して内照明式看板1が消灯することを防止する。 Moreover, according to the internal lighting type | formula signboard 1 which provided the charging / discharging control apparatus 10, based on control of the control part 11, it selects in order from the battery 13 with the low charging rate from the battery 13 with which it was equipped, and is generated with the solar cell 12. The charged power is charged. Therefore, even with the solar cell 12 whose amount of power generated depends on the weather, the plurality of batteries 13 can be charged efficiently, and the internal lighting type signboard 1 is prevented from being extinguished due to insufficient charging of the battery 13. .
なお、上述した第1の実施形態においては、充放電制御装置10を内照明式看板1に設ける構成として説明したが、このような形態に限定されることはなく、本発明の要旨を逸脱しない範囲において適宜変更可能である。具体的には、充放電制御装置10を例えば歩道を照らす街灯や公園に設置された時計に設ける構成としても良い。また、太陽電池12や照度計16を内照明式看板1に設けずに内照明式看板1と離間した場所に配設する構成としても良い。また、光源14は、LEDに限定されることはなく、蛍光管、CCFL管(冷陰極管)、及びネオン管等であってもよい。 In addition, in 1st Embodiment mentioned above, although demonstrated as a structure which provides the charging / discharging control apparatus 10 in the internal illumination type | mold signboard 1, it is not limited to such a form and does not deviate from the summary of this invention. The range can be changed as appropriate. Specifically, the charge / discharge control device 10 may be provided in, for example, a streetlight that illuminates a sidewalk or a clock installed in a park. Moreover, it is good also as a structure which arrange | positions the solar cell 12 and the illuminance meter 16 in the place spaced apart from the internal illumination type | mold signboard 1 without providing in the internal illumination type | formula signboard 1.
