Abstract
An LED light module () for street lamp includes a frame (), electrodes () and a heat sink () mounted in the frame, an LED chip () attached on a top of the heat sink; and a silicon lens () 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 () at either end and a depressed part () 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.
