The difference between continuous lighting and continuous light storage

1, light storage material is a kind of material that can store its light energy when irradiated by visible light and ultraviolet light. Then, after the light source is evacuated to produce fluorescence, the stored light energy is slowly released in the dark. Optical storage materials can be widely used in military, navigation, fire protection, transportation and other fields. For example, in the event of sudden disasters such as earthquakes and fires at night, there are often power outages or emergency lighting facilities, and people need clear night vision guidance to escape smoothly in the dark. In theaters, schools, hospitals, residential corridors and other public places, light storage materials can guide people to enter and exit safely when lights are suddenly turned off or power is cut off at night. Night vision indicator lights are needed in highways, overpasses, underground passages and other places.

2, continuous lighting is relative to the flash. Continuous light is the traditional light used to shoot portraits. Before the flash appeared, continuous light sources were used to shoot portraits. Continuous light used in photography has the characteristics of weak intensity, large color temperature change and easy control of the depth of field of the picture. The light effect seen when WYSIWYG distribution is basically the light effect of the final photo.
