CALCULATING METHODS OF FLOOR ILLUMINANCE BY EMERGENCY LIGHTS IN FIRE SMOKE TAKING INTO ACCOUNT OF SMOKE ADHESION

摘要

In order for emergency signs to function properly for evacuation in fire, we need to secure the sufficient visibility in every situation, therefore it is necessary to establish a calculation method of luminous stimuli in fire smoke to evaluate evacuee's visibility quantitatively. This paper propose a calculation model of floor illuminance in fire-smoke taking into account of smoke fluidity and adhesion thereby contribute to the suitable sign design and layout for evacuation.
