The invention discloses a skylight light transmittance button indicating lamp control circuit. The control circuit comprises an indicator lamp module, a power supply module for supplying power to theindicator lamp module, and a brightness control module for controlling the magnitude of current transmitted to the indicator lamp module. The power supply module supplies power to the indicator lamp module through the brightness control module. The brightness control module comprises a control signal, and under the state that the control signal is not output, the brightness control module controlsthe magnitude of the current conveyed to the indicator lamp module to be the first current magnitude; under the state that the control signal is output, the brightness control module controls the magnitude of the current transmitted to the indicator lamp module to be the magnitude of the second current; and the first current is greater than the second current. According to the skylight light transmittance button indicating lamp control circuit, the brightness of the indicator lamp module can be adjusted under the conditions of sufficient light and insufficient light, and the user experience is effectively improved.
本发明公开了一种天窗透光率按钮指示灯控制电路,包括指示灯模块、为指示灯模块供电的电源模块、以及用于控制输送至指示灯模块的电流大小的亮度控制模块;供电模块通过亮度控制模块为指示灯模块供电;亮度控制模块包括控制信号,控制信号无输出的状态下,亮度控制模块控制输送至指示灯模块的电流大小为第一电流大小;控制信号有输出的状态下,亮度控制模块控制输送至指示灯模块的电流大小为第二电流大小;第一电流大小大于第二电流大小。本发明其能针对光线充足以及不充足的情况下对指示灯模块进行亮度调节,有效提升了用户体验。
