With this technology, the LED chips are in the form of a semiconductor chip, which is neither encased nor connected. The semiconductor chip is described as a "Die". This LED chip is processed by means of a special procedure which is called "Die Bonding". Here the individual chips are placed on the PCB and using the Wire Bonding method, connected to the contact surface of the PCB, which are described as "Pads". Gold wires in the micrometer range are used for contacting. The COB technology allows for virtually limitless freedom of scope for the PCBs and thus serves as the basis for totally unique LED solutions.

COB LED is the most popular item in WEIDI. It help to solve the problem that LED lamp are not bright enough to replace halogen with a beautiful design. A full sery of COB LED including COB LED bulb, COB LED lamp, COB LED tube, COB LED machine light, COB LED table light, COB LED sewing machine lights, ect.
