Lighting in Confined Spaces:Areas such as elevator shafts and pipe floors. The hollow structure allows for flexibility to adapt to irregularly shaped mounting surfaces. Actual measurement data shows that in a 15cm diameter curved channel, the illuminance uniformity reaches 0.8 or higher (industry standard is ≥0.6).
High Safety Requirements Locations: Hospitals and chemical plants prioritize hollow designs due to the absence of glass components, achieving an explosion-proof rating of IP65. Comparative tests show that in environments ranging from -30℃ to 70℃, the light decay rate is <3%/year, far exceeding that of ordinary emergency lights.
