INDICATOR LIGHT AND ROAD AUXILIARY FACILITY
To provide an indicator light that can continuously exhibit a visual guidance function.SOLUTION: An indicator light is arranged in a housing and includes: a light emitting unit 7 having one or a plurality of light sources; and a light source control unit 8 causing the light emitting unit 7 to emit light at a prescribed light emission cycle. The prescribed light emission cycle includes a first period and a second period. In the first period, the light source control unit 8 supplies power to constantly light the light emitting unit 7 at a first brightness for the first period or supplies power to the light source at a frequency in which the light emitting unit 7 appears to be always lit for the first period with the first brightness due to the afterimage phenomenon of the human eye. In the second period, the light source control unit 8 supplies power to constantly light the light emitting unit 7 with a second brightness lower than the first brightness for the second period or supplies power to the light source at a frequency at which the light emitting unit 7 appears to be constantly lit for the second period with the second brightness due to the afterimage phenomenon of the human eye.SELECTED DRAWING: Figure 3
【課題】視線誘導機能を継続的に発揮できる表示灯を提供する。【解決手段】表示灯は、筐体内に配置され、一つまたは複数の光源を含む発光部７と、発光部７を所定の発光周期で発光させる光源制御部８とを備える。所定の発光周期は第１期間と第２期間とを含む。光源制御部８は第１期間においては、発光部７を第１輝度で第１期間にわたって常に点灯させるための電力供給、または、人の目の残像現象によって見かけ上発光部７が第１輝度で第１期間にわたって常に点灯しているように見える周波数の電力供給を光源に対して実行し、光源制御部８は第２期間においては、発光部７を第１輝度よりも低い第２輝度で第２期間にわたって常に点灯させるための電力供給、または、人の目の残像現象によって見かけ上発光部７が第２輝度で第２期間にわたって常に点灯しているように見える周波数の電力供給を光源に対して実行する。【選択図】図３
