Method for preparing radiating coating of light-emitting diode (LED) lamp

Abstract

The invention relates to a method for preparing a radiating coating of a light-emitting diode (LED) lamp. The radiating coating is prepared from the following components in percentage by weight: 30 to 60 percent of water-base resin, 20 percent of low-molecular polyamide, 10 to 20 percent of carbon nano tube, 1 to 5 percent of silicane coupling agent KH550, 5 to 40 percent of aluminum powder, 10 percent of rare-earth element oxide, 13 percent of silicon nitride, 15 to 20 percent of acetone, 1 to 2 percent of curing agent, 2 to 5 percent of mixture of dust preventive and smoothing agent and 3 to 5 percent of phenol. The radiating coating has high-radiation cooling performance, is used for reducing the surface temperature of a radiating cup, an aluminum substrate, a lampshade and the like in the LED lamp, and has excellent protective and decorative functions; due to the addition of a nano material unit, the contact area of a radiating device and the outside is increased, and a radiating effect is improved obviously; and due to the addition of the rare-earth element oxide, the activity of the radiating coating composition can be improved, and the radiating coating is also an optimal material for doping and stabilizing a coating structure.

AI Technical Summary

Benefits of technology

This patented technology relates to an improved thermal conductive fluid that can be applied onto light fixtures like LED lights or other devices with better radiative performance by reducing their temperatures without adding too much weight on them. Additionally, this new liquid helps protect these components from damage during manufacturing processes such as solder bonding process. Overall, this innovator provides technical benefits over existing fluids.

Problems solved by technology

The current method described in the patents involves adding thermally-conductive material (such as ceramic) into an epoxy resin or silicon rubber composition called glue before applying it onto the lamp tube surface during assembly process. This helps prevent damage from excess temperatures caused by high light output levels. However, these methods suffer from issues like insufficient durability over time due to factors including lack of good contact between the metal foil on top of each chip and the glass cover plate, difficulty in handling small parts when applied manually without causing cracks at any points along their edges, and difficulties in adjustment after application.
