Abstract

The invention relates to an LED lamp module capable of directly packaging an LED chip on a radiating supporting carrier circuit. The LED lamp module comprises a solid radiating supporting lamp carrier circuit and the LED chip, wherein the solid radiating supporting lamp carrier circuit comprises a solid radiating supporting lamp carrier and a circuit which is integrated with the solid radiating supporting lamp carrier, and the LED chip is directly packaged on the solid radiating supporting lamp carrier circuit. The invention also relates to a method for manufacturing the LED lamp module. Compared with traditional LED modules, the LED lamp module capable of directly packaging the LED chip on the solid radiating supporting lamp carrier circuit shortens the heat transfer distance greatly, the heat transfer effect is good, surface mounting technology (SMT) welding is not required to be performed on LEDs and components, the whole manufacturing process is shortened, simultaneously, materials are saved, the manufacturing time is shortened, the production efficiency is greatly improved, and the production cost is reduced.

Description

technical field [0001] The invention belongs to the field of LED application, and in particular relates to an LED lamp module which directly encapsulates an LED chip on a carrier circuit of a three-dimensional heat dissipation supporting lamp. Background technique [0002] The combination of the traditional three-dimensional heat dissipation support lamp carrier and circuit board is to make an aluminum-based circuit board or copper-based circuit board, or a ceramic-based circuit board. After soldering the components through SMT, paste the back of the circuit board on the three-dimensional heat dissipation Supporting the lamp on the carrier, this method has a long heat transfer distance and layers of thermal resistance, resulting in low heat conduction rate, slow heat conduction, and the production process is quite cumbersome and takes a long time to produce. [0003] How to reduce thermal resistance so that the heat generated by LED can be dissipated as soon as possible has ...
