    • A method of manufacturing a micro-lens array and light-emitting device, comprising forming a first structured polymer film with close packed surface cavities having a mean diameter of less than 20 micrometers and a relatively lower surface energy surface, forming a transparent second structured film with an array of microlenses formed thereon corresponding to the cavities of the first structured film, wherein the second structured film comprises a relatively high surface energy material and has a refractive index greater than 1.45, and wherein the microlenses are randomly distributed, separating the second structured film with the micro-lens array from the first structured polymer film, and attaching the second structured film to a transparent substrate or cover of a light-emitting device through which light is emitted. Use of microlens arrays formed from relatively high surface energy materials enables matching refractive index of microlens array to that of light-emitting devices substrate or cover through which light is emitted and relatively high elastic modulus providing good scratch resistance.

    • An LED light module (100) for street lamp includes a frame (1), electrodes (5) and a heat sink (4) mounted in the frame, an LED chip (2) attached on a top of the heat sink; and a silicon lens (3) formed on the frame and closely sealing the LED chip therein. The LED light module is an integral structure with the silicon lens being formed thereon through an in-mold process. The silicon lens lengthwise includes two convergent parts (31, 33) at either end and a depressed part (32) at middle thereof for consecutively bridging the two convergent parts. Thus the exit light beam from the LED light module is elongated without light loss. A one-body molding process for manufacturing the LED light module is disclosed as well, which is in high-efficiency, and adapted for a mass production.
    • 一种用于路灯的LED灯模块(100),包括框架(1),安装在框架中的电极(5)和散热片(4),安装在散热器顶部的LED芯片(2) 和形成在框架上并将LED芯片密封在其中的硅透镜(3)。 LED灯模块是通过模内工艺在其上形成硅透镜的整体结构。 硅透镜纵向包括在任一端的两个收敛部分(31,33)和在其中间的凹陷部分(32),用于连续地桥接两个收敛部分。 因此,来自LED灯模块的出射光束延长而没有光损失。 还公开了用于制造LED灯模块的单体成型工艺,其高效率并且适于批量生产。
