The LED filament lamp is an incandescent lamp manufactured by using an LED in appearance, the LED filament is used as a light source, the LED filament can emit light at 360 degrees in a full angle, the light is emitted at a large angle, and a three-dimensional light source can be realized without adding a lens.

When the bulb of the LED filament lamp is produced, glass needs to be sintered at high temperature to remove impurities, then nitrogen is added for practicality after vacuumizing, and in order to prevent the light emitted by the filament from dazzling, the inner wall of the glass bulb needs to be subjected to frosting treatment, so that the glass bulb has good diffuse transmission performance. Frosting of glass bulbs typically involves: 1. and 2, performing sand blasting treatment on the glass bulb, and corroding the surface of the glass bulb by using hydrofluoric acid to enable the inner wall of the glass bulb to be milky.

However, because the requirement for environmental protection of production and processing is higher and higher, the two treatment methods are difficult to meet the standard of environmental protection, so that a new coating is needed, the coating can be coated on the inner wall of a glass bulb to form a ground glass bulb, and in the production process of an LED filament lamp, the coating is high-temperature-resistant to sintering, cannot volatilize and fall off, can be used in a vacuum state, and is more environment-friendly.

Disclosure of Invention

The invention overcomes the defects of the prior art, and provides the coating which enables the glass bulb to have the frosted effect, the coating is coated on the inner wall of the glass bulb to form the frosted glass bulb, so that the light emitted by the filament cannot be dazzled, and the coating is high-temperature resistant and can be used in a vacuum state.

In order to achieve the purpose, the invention is realized by adopting the following technical scheme.
