摘　　要：为了提高茶叶LED光辐照萎凋效率及节能性,通过试验测定萎凋中不同照射距离各受光点和受光面的光均匀性和光效。结果表明,不同LED光质发光面与受光面的照射距离(100~500 mm)越大,变异系数越小,受光面的均匀性越好;通过综合光能利用效率和在制叶失水速率分析得出,在照射距离200~300 mm条件下开展茶叶萎凋,效果最优。In order to enhance the withering efficiency and energy saving of light emitting diodes （LED） in the process of tea wither- ing, the uniformity and efficiency of the LED light and light luminous surfaces were measured and analyzed under different distances from the lighting source. The results showed that the farther the lighting source （ 100-500 mm）, the smaller the coefficient of varia- tion and the better uniformity of light-receiving surface. Based on a comprehensive testing on light use efficiency and water loss rate of tea leaves, it is concluded that the best withering can be achieved at a lighting distance of 200-300 mm.
