Abstract: The invention discloses a method for arranging LED arrays and the LED arrays arranged on a PCB. The LED arrays are used for improving illumination consistency of LEDs on the PCB and reducing energy consumption. The method includes the following steps that firstly, the PCB is selected according to materials; secondly, the LEDs are installed on the PCB, and the minimum distance between a single LED in the LED arrays and the edge of the PCB is set; thirdly, the distance between the adjacent LEDs in the LED arrays is set; fourthly, the arrangement shape of the LEDs forming the LED arrays is set; fifthly, the distance between the LED arrays on the PCB and with the set shape in the fourth step is set. Compared with an ordinary method for evenly arranging the LED arrays at equal intervals, the method for arranging the LED arrays on the PCB has the advantages that the illumination consistency is obviously improved, and the service life of the LEDs can be prolonged. The invention further discloses the LED arrays capable of improving illumination consistency and arranged on the PCB.
本发明公开了一种LED阵列的排布方法及排布在PCB板上的LED阵列,用于提高PCB板上LED的光照一致性以及减少能量消耗,所述方法包括以下步骤:A.根据材料选取PCB板;B.将LED安装在PCB板上,设置LED阵列中单个LED与PCB板边缘之间的最小距离;C.设置LED阵列中相邻LED之间的距离;D.设置构成LED阵列的LED的排列形状;E.设置PCB板上具有步骤D设定形状的LED阵列之间的距离,本发明的PCB板上的LED阵列的排布方法与通常的等间距均匀排列方法相比,明显提高了光照一致性,同时有助于延长LED的使用寿命。同时,本发明还公开了一种能提高光照一致性的排布在PCB板上的LED阵列。
