Why do you have a light bulb or a light bulb? What's the difference between a light and a light cup? There's a difference in use, how do you differentiate them?
Well, that's two concepts. The lamp is the variety of the lamp, and the lamp cup is the shape of the light source. The light bulb is used as a light source.
This is the inner light cup.The light bulb is the product light cup is the general term.
The lamp is made up of lamp holder and lamp cup. The light bulb is the light bulb in the light bulb, so if the light is broken, it's usually just a light cup. When you buy a light bulb, the lamp is only a lamp holder, so you must buy a lamp. Does that make sense?
