5050 lamp beads LED lumen value calculation formula?Answer: In principle, the so -called LED lumen is the so -called optical flux. The number of lumens emitted by 1W is also luminous efficiency. Therefore, the higher the optical flux created by 1W represents the better the lighting efficiency.However, the increase in light flux is achieved by increasing the current. This may bring 2 negative effects: 1. The current is easy to cause light decay.2. After the optical flux is high, the color rendering will decrease.These two indicators are the most critical indicators to measure LED. |
