Practical brightness balance control strategy

Brightness balance control strategy

This strategy takes advantage of the light and dark adaptation, that is, to balance the brightness level of the adjacent areas to reduce glare and shadow, and reduce the range of light adaptation. For example: the use of grid or curtain to reduce the daylight in the indoor wall formation of the light spot; when the outdoor brightness increases, open the indoor artificial lighting, in the outdoor brightness reduction, close the indoor artificial lighting. The brightness balance control strategy is usually used for the control of tunnel lighting. The higher the outdoor brightness is, the higher the brightness of the tunnel illumination is.

If the brightness balance control of the building is also realized by the illumination sensor, the logic of the control is just opposite to the tunnel control.
