    • After measurement, light-emitting elements are temporarily numbered (1), . . . in measuring order and arranged successively on a temporary palette. In parallel with this operation, measured light intensity data are input to a computer system in association with the temporary numbers (1), . . . In the computer system, the measured light intensity data are rearranged according to predetermined algorithm to make the light intensity values of adjacent light-emitting elements substantially equal, so that the temporary numbers (1), . . . are rearranged on a memory in accordance with the rearranged data. The rearranged data are sent from the computer system to a robot, so that the light-emitting elements on the temporary palette are arranged on a taping.

    • In an LED device, an opening portion of a package in which a plurality of five light-emitting elements are mounted is filled with a transparent epoxy resin and sealed with the resin. The transparent epoxy resin is shrunk when cured. Hence, the surface of the transparent epoxy resin is dented in the center portion so that the outer edge portion becomes higher than the center portion. The light-emitting elements located at opposite ends are the highest in element height among the five light-emitting elements. Hence, when the light-emitting elements are mounted at opposite ends of a single row, distances from light-emitting surfaces of the five light-emitting elements to the surface of the transparent epoxy resin are made uniform and luminous intensity distribution characteristics thereof are made uniform. Tips of leads are further bent up along side surfaces of the package. Hence, when the LED device is soldered onto a mount board, solder is deposited even on the up-bent tips of the leads, so that surface tension of solder is balanced on the front and rear of the package. As a result, the LED device can be mounted in a predetermined position while prevented from sliding. In an LED lead frame, hanger leads are provided so as to be extended in three directions of a package. Hence, the electrically conductive leads can be bent stably and accurately without tottering of the package in the process of bending the electrically conductive leads.
    • 在LED器件中,安装有多个五个发光元件的封装的开口部分填充有透明环氧树脂并用树脂密封。 固化后,透明环氧树脂收缩。 因此,透明环氧树脂的表面在中心部分凹陷,使得外边缘部分变得高于中心部分。 位于相对端的发光元件在五个发光元件中的元件高度最高。 因此,当将发光元件安装在单列的相对端时,将五个发光元件的发光表面到透明环氧树脂的表面的距离均匀并且使其发光强度分布特性 制服。 引线的尖端进一步沿着封装的侧表面弯曲。 因此,当将LED器件焊接到安装板上时,甚至在引线的上弯顶端上沉积焊料,使得焊料的表面张力在封装的前部和后部平衡。 结果,LED装置可以安装在预定位置,同时防止滑动。 在LED引线框架中,提供悬挂引线以在封装的三个方向上延伸。 因此,在导电引线弯曲的过程中,导电引线可以稳定且准确地弯曲而不会使封装弯曲。
