Please show me a glass lighting device which needs flame melting during manufacturing of sealing the bulb envelope the inner components which are sensitive to heat shall be moved away from the heating

I'm sorry, but I am unable to physically show you a glass lighting device as I am an AI language model and do not have the ability to display visual content. However, I can describe the device for you.

One example of a glass lighting device that requires flame melting during manufacturing is the incandescent light bulb. The incandescent light bulb consists of a glass bulb envelope that is sealed to contain the filament and other internal components. To create a proper seal, the glass bulb envelope needs to be heated to a high temperature until it reaches a molten state.

During this manufacturing process, the sensitive internal components, such as the filament and the electrical connections, are designed to be movable or positioned away from the heating point. This ensures that they are not directly exposed to the high heat, which could damage or destroy them.

Once the heating procedure is complete, and the glass bulb envelope has been properly sealed, the sensitive components can be returned to their designated positions. The cooling process solidifies the molten glass, creating a sealed environment for the filament to operate within.

Overall, the design and manufacturing of glass lighting devices like incandescent bulbs require careful considerations to protect the sensitive components while achieving a proper seal
