Fires caused by the concentration of solar radiation through transparent objects have been discussed mainly from a theoretical perspective, while experimental verification based on actual residential fire cases remains limited. This study analyzes the ignition mechanism of a residential fire suspected to have resulted from solar radiation concentration through a spherical transparent lighting device. In January 2026, a fire occurred in a detached house in Yongin, Republic of Korea. Fire scene investigation identified localized burn patterns near a window, and no clear evidence of electrical or mechanical failure was found. A spherical transparent lighting device was located adjacent to combustible materials at the presumed point of origin, indicating the possibility of a non-electrical ignition source. To verify this hypothesis, reproduction experiments were conducted under actual sunlight conditions using a spherical transparent lighting device identical to that found at the fire scene, with black Hanji paper used as an indicator combustible material to clearly observe localized thermal response due to its high absorptivity and thermal sensitivity. The results showed that solar radiation transmitted through the spherical transparent lighting device was refracted and concentrated into a localized focal region, resulting in smoke generation and localized surface charring. These findings suggest that spherical transparent lighting devices can act as non-electrical ignition sources under specific solar exposure conditions and highlight the necessity of considering solar radiation concentration as a potential non-electrical ignition factor in fire origin investigations.
