LIGHTING DEVICE

摘要

PURPOSE: A lighting device is provided to conveniently control the color of light by connecting a light color and light emission start voltage with other light emitting devices in parallel to each other. CONSTITUTION: A second light emitting device(102) is connected to a first light emitting device(100) in parallel. The second light emitting device emits second light with a wavelength longer than first light emitted from the first light emitting device. The second light emitting device emits the second light with voltage lower than the first light emitting device. The mixed color of the first light and the second light is controlled by the voltage applied to the second light emitting device and the first light emitting device.
