Faced with skyrocketing cost of energy and environmental concerns, builders, architects and lighting experts are increasingly turning to daylight as a primary source of illumination.

To take full advantage of daylight integration, buildings should have automated controls that either turn off or dim artificial light in response to the available daylight in the space. This is called 'daylight harvesting'.

We supply a simple and cost effective solution for daylight harvesting. Using our own design of interface and using photocells to measure ambient lux levels we can automatically calculate how much artificial light is needed. Our solution will then adjust the lighting output according to the signal from the daylight sensor. This in turn uses the least amount of electric to maintain the correct lighting levels.

Features:
• Provides an energy saving without sacrificing visual comfort
• With ambient light dependent control
• Directly connected to 1-10V interface
• Simple setting of the target light level by mean of potentiometer






The lamp lights on 100% illumination or dims to maintain the preset illumination level against ambient light
The lamp dims to minimum light level but never turn off even if with sufficient ambient light
Users can switch off the light manually












Ambient light larger than present illumination level (set by 1-10V daylight sensor), the lamp stays off
Ambient light lower than present illumination level, the lamp switches on when motion is detected
The lamp lights on 100% illumination or dims to maintain the preset illumination level against ambient light

The lamp dims to minimum light level but never turns off even if with sufficient ambient light
When no motion is detected, the lamp switches off after hold time












Ambient light larger than present illumination level (set by 1-10V daylight sensor), the lamp stays off
Ambient light lower than present illumination level, the lamp switches on when motion is detected
The lamp lights on 100% illumination or dims to maintain the preset illumination level against ambient light

If with sufficient ambient light, the lamp turns off at once, even with motion trigger
If with insufficient ambient light, the lamp dims to a standby dimming level (set in the motion sensor) when no motion detected during hold time, and then switches off after standby period
