1 | Ratio of the utilized flux to the luminous flux leaving the luminaires. | |
2 | Ratio of the absorbed radiant or luminous flux to the incident flux. | |
3 | Of a source. Quotient of the luminous flux emitted and the power consumed. | |
4 | It is helpful to reducing the uncertainty of measuring LEDs luminous flux with integrating spheres. | |
5 | High-purity imported aluminum reflector is used to effectively improve the reflectivity and ensure the output of luminous flux. |
