Abstract

In this study, comparative analysis on the actual condition and perception of residential LED lighting usage was performed between general consumers lived in Busan city and lighting experts. As a result, 78.6% of consumers have used LED lighting and their satisfaction level was 69.5%. The dissatisfaction level of experts was higher than consumers. Both groups have perceived ‘long life’ and ‘low power rates’ as merits, and ‘low-quality products’, ‘high price’ and ‘glare’ as demerits. While, experts have perceived ‘diversity of design’, ‘changeability on lighting atmosphere’ as merits, and ‘low-quality products’ as demerits. Consumers were more aware of ‘cold light’ and ‘light and dark deviation’ as a disadvantage. Both groups perceived the LED lighting as a main lighting source for near future residential lighting. Consumers have prioritized the order of ‘quality’, ‘price’ and ‘electricity charges’ as consideration when purchasing products. Experts perceived more ‘gentleness’, ‘brand’, ‘authentication’, and ‘design diversity’ than consumers. In both groups, ‘quality improvement’ was the most demanded for LED lighting improvement direction, and ‘convenience’ of replacement and maintenance was also high. On the other hand, consumers strongly demanded ‘cheaper price of LED lighting’, but experts demanded ‘the supply of high-quality product’.
