More Information
Summary:The utility model belongs to the technical field of light source measurement, specifically a LED light flux measurement device. The device comprises a reflection cup, a clamp, a light-flux meter and a power supply, wherein the clamp fixes a LED at the bottom of the reflection cup, the LED emits light towards the opening of the reflection cup, the light-flux meter is tightly fixed at the opening of the reflection cup to receive optical signals, the power supply is a constant-current power supply for driving the LED. The total light flux of the LED is focused by the reflection cup and then collected and measured by the light-flux meter, and finally the light-flux meter displays the value of total light flux. The utility model has the advantages of simple structure and high measurement accuracy.
