    • Provided is a lighting device which can be dimmed and subjected to change in color temperature of the lighting color in accordance with a dimming level. To the lighting device, AC power under phase-controlled is supplied. The lighting device is provided with a light emitting elements array and a switching unit. The light emitting elements array includes a plurality of light emitting elements, which are two or more types of light emitting elements having different lighting colors. The switching unit switches an electrical connections between the light emitting elements included in the light emitting elements array so as to change the number of light emitting elements inserted in series to a power supply path and the proportion of numbers of light emitting elements per lighting color among the number of the inserted light emitting elements in accordance with a voltage supplied to the light emitting elements array.
    • 提供一种照明装置,其能够根据调光水平变暗并经受照明颜色的色温变化。 向照明装置提供相控制的交流电源。 照明装置设置有发光元件阵列和开关单元。 发光元件阵列包括多个发光元件,它们是具有不同照明颜色的两种或更多种类型的发光元件。 切换单元切换包含在发光元件阵列中的发光元件之间的电连接,以便将串联插入的电源路径的发光元件的数量和每个照明颜色的发光元件的数量的比例 根据提供给发光元件阵列的电压的插入的发光元件的数量。
