## Abstract

An LED filament module includes an LED filament and a fireproof tube mounted on an outer surface of the LED filament. The fireproof tube includes a main body having a tubular shape and a gum layer mounted on an outer surface of the main body. The main body is made of alkali-free glass fibers weaving together. The gum layer is made of an organic silicone that is treated by vulcanization.

## Claims

### Claim 1
