摘要
利用单个LED芯片的照度公式推导出圆形LED阵列的照度公式和光斑的发散角公式,利用圆形LED阵列的照度公式和光斑的发散角公式研究了圆形LED阵列的照度峰值和光斑发散角随目标距离、结构参数以及芯片数的变化关系。得出了这三种情况下照度峰值和光斑发散角的变化规律。这些规律为利用圆形LED阵列来实现照明设计提供了定量的理论±据。
Using the single LED illumination formula, the illumination formula and the divergence angle formula of LED roundness array are deduced. The illumination changing and the divergence angle of LED roundness array with the number of LED and the structural parameters and the target distance are studied. The changing rule of the peak in_tensity of illumination and the divergence angle are derived, in order to lighting design using the LED roundness array provides a theoretical basis.
