This research aimed to develop a lighting controller for LED lamps coordinated with day lighting (LCTL) for replacing the lamps that were installed near windows. This device would control LED lamps to work appropriately at daylight levels. The results revealed that the developed device could control the lighting of LED lamps coordinated with day lighting between 0 and 338 lx. This device consumed about 18.83 W. It could save 9.17 W of energy when compared to a 28 W T5 fluorescent lamp. The measurement and calculation of the energy saving of this device showed that it could save approximately 0.23 kWh/lamp/day. A computer simulation was employed to analyze the lighting through windows in two levels, i.e., high and low transmittance of glazed window. The simulations showed that the device could save 66 kWh/lamp/year for a high transmittance window. The device could save 21 kWh/lamp/year from the north side, 35 kWh/lamp/year from the south side, and 33 kWh/lamp/year from the east and the west sides for low transmittance window. Further studies would adapt this device into microcontroller-based systems, integrated LCD to monitor a setting illuminance and a work plane illuminance. A wireless control system would be used for this system.
