电的/照明的
A lamp, in technical usage, is a replaceable component such as an incandescent light bulb, which is designed to produce light from electricity. These components usually have a ceramic or metal base, which makes an electrical connection in the socket of a light fixture. This connection may be made with a threaded base, two metal pins, or a "bayonet mount" (candelabra base). Re-lamping is the replacement of only the removable lamp in a light fixture.
