    • A dimmer switch for controlling the amount of power delivered to and thus the intensity of a lighting load comprises a visual display operable to provide a visual indication representative of energy savings and usage information. The visual display may comprise a single visual indicator or a linear array of visual indicators. The visual display is illuminated in a first manner when the intensity of the lighting load is less than or equal to a predetermined eco-level intensity, and is illuminated in a second manner when the intensity of the lighting load is greater than the eco-level intensity. For example, the single visual indicator may be illuminated a first color, such as green, when the intensity of the lighting load is less than or equal to the eco-level intensity, and illuminated a second different color, such as red, when the intensity of the lighting load is greater than the eco-level intensity.
    • 用于控制发射的功率量和因此照明负载的强度的调光开关包括可操作以提供表示节能和使用信息的视觉指示的视觉显示器。 视觉显示可以包括单个视觉指示符或视觉指示器的线性阵列。 当照明负载的强度小于或等于预定的生态水平强度时,以第一种方式照亮视觉显示,并且当照明负载的强度大于生态水平时,以第二种方式被照亮 强度。 例如,当照明负载的强度小于或等于生态水平强度时,单个视觉指示器可以照亮第一颜色,例如绿色,并且当第二颜色(例如红色)照亮时,可以照亮第二种不同颜色 照明负荷强度大于生态水平强度。
