Development of Luminaire Design Prototype for the Landscape of Chudhadhuj Royal Residence

The main contribution of this research is to demonstrate the design process and development of the luminaire design prototype for the landscape of Chudhadhuj Royal Residence. The historical importance of the context, as the former royal residence of King Rama V of Thailand, is the main focus of the study to establish the design criteria. Three luminaire prototypes including: lamp post; bollard; and bollard with perforated patterns are developed based on extensive reviews of literature on history, and architectural conservation as well as on the identity of the context, and luminaire design guidelines and site surveys for luminaire installation. The evaluation of conservation aspects based on expertise is collected through questionnaires showing computer-simulated images in the real environment. The assessment by the experts from design and/or conservation fields reveals that the luminaire design prototypes can be further developed especially in terms of architectural and landscape conservation aspects for the cultural landscape. It also shows the possibility of utilizing the solar energy-operated hybrid system as an alternative energy source to improve landscape lighting and enhance safety around the premises. Therefore, the researcher could lead the luminaire prototypes to be patented.
