You can use the heat gun to repair the LED lights for the following reasons:

The temperature of the hot air gun is adjustable, so it won’t damage the components due to the high temperature.
The LED light pins on the circuit board are on the back of the board and will not directly blow to the light-emitting surface of the LED light.
The temperature of the LED lamp surface material is designed to far exceed the melting point of solder.
