Abstract:
1. A total luminous flux measurement system for measuring a total luminous flux of a light emitting component, the light emitting component having a projection light field and a central normal, the total luminous flux measurement system comprising: a light receiving module, disposed on the central normal, the light receiving module dividing the projection light field into a forward light field and a side light field, the light receiving module for receiving a beam projected by the light emitting component in the forward light field to obtain a forward luminous flux; a first light detector, disposed on a side of the light receiving module, the first light detector for receiving a beam projected by the light emitting component in the side light field to obtain a first side luminous flux; a second light detector, disposed on a side of the light receiving module opposite to the first light detector, the second light detector for receiving a beam projected by the light emitting component in the side light field to obtain a second side luminous flux; and a processing module, electrically connected to the light receiving module and the first light detector, the processing module for calculating the total luminous flux of the light emitting component by determining a field pattern of the projection light field according to the forward luminous flux and the first side luminous flux, the processing module comprising:
