PURPOSE: To provide a dummy lamp lighting device capable of lighting similar to a candle fire simulatively and being utilized as the lamp of a miniature tower or a garden lantern, etc. CONSTITUTION: A switch 5 is in an ON condition when a miniature garden lantern is placed, and is in an OFF condition when the garden lantern is raised. Therefor, the output of a capacitor 10 has a high level to oscillate an oscillation circuit, composed of a resistance 11, a capacitor 13, and an inverter 12, to light-emit red and green light emitting diodes 22 and 23 by the dividing output of a binary counter 15. Since respective stages of the divided output are added to light-emit the respective light emitting diodes, the respective light emitting levels of red and green are changed; and when the red and the green are light- emitted concurrently, they are mixed to be turned into yellow. When the switch 5 is made the ON condition again, a lamp is extinguished after a fixed time. Lighting, similar to the fire of a candle, and safety can be obtained, and also management can be facilitated. |
