Abstract Taking lighting layout modes commonly used in the engineering design as an example, using point illuminance calculation method, the illuminance of normal lighting and emergency lighting in the corridors and staircases are calculated in details. The results show that the lighting design methods that have been widely used in engineering design cannot meet the illuminance requirements for the corridors and staircases stipulated in the existing code；and the illuminance of the emergency lighting cannot meet the requirements of the relevant compulsory article.
