摘要： A locking connection device, an LED box and an LED display screen are provided. The device includes a locking module and an inserting module. The locking module includes a hook and a bump matching with each other. The inserting module includes a fixing pin and a fixing hole matching with each other. The fixing pin and hook are fixed on a first base, and the bump and the fixing hole are fixed on a second base. The locking connection device further includes a driving module that propels the hook and the fixing pin to move synchronously. When the driving module finishes a travel, the hook and the bump are securely connected, and the fixing pin and the fixing hole are securely connected. Since the locking module according to the present invention locks the movement of the first base and the second base along the axial direction of the fixing pin and meanwhile the inserting module locks a circumferential movement of the fixing pin, the first base and the second base are securely fixed. Additionally, the sizes of the fixing pin, the fixing hole, the hook and the bump can be selected to match the weight of the box to lock and connect heavy boxes, thus realizing a convenient installation.
摘要翻译： 提供锁定连接装置，LED盒和LED显示屏。 该装置包括锁定模块和插入模块。 锁定模块包括彼此匹配的钩和凸块。 插入模块包括彼此匹配的固定销和固定孔。 固定销和钩固定在第一基座上，凸块和固定孔固定在第二底座上。 锁定连接装置还包括驱动模块，该驱动模块推动钩和固定销同步地移动。 当驱动模块完成行驶时，钩和凸块牢固地连接，固定销和固定孔牢固地连接。 由于根据本发明的锁定模块沿着固定销的轴向锁定第一基座和第二基座的移动，同时插入模块锁定固定销的周向运动，所以第一基座和第二基座是 安全固定。 另外，可以选择固定销，固定孔，挂钩和凸块的尺寸，使其与箱体的重量相匹配，锁紧重物箱，实现安装方便。

摘要： 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.
