Patent ID: 8293548

Claim:
A method of manufacturing an LED light module comprises steps of: (1) providing a frame with electrodes and a heat sink being secured therein, and an LED chip being attached onto a top of the heat sink, thereby the frame being assembled; (2) preheating the frame; (3) forming a silicon lens on the assembled frame through an in-mold process so as to obtain an LED light module; and releasing the LED light module from the mold and further baking the same; wherein at the step of (3), the frame is mounted in a mold with the LED chip upward to a cavity of the mold, and the mold is designed with the cavity in a shape of peanut; silicon resin is injected into and filled in the cavity of the mold; thereafter, the mold is heated, thus the silicon resin is cured to form a silicon lens on the frame and seals the LED chip on the top of the heat sink; herein, the silicon lens is in a shape of peanut, and intimately engaged with a surface of the LED chip.
