A lamp includes a lamp cover, a light emitting diode (LED), and a lamp holder. The lamp holder includes at least two insulation parts firmly combined or attached to each other and formed an inner cover, in which a plurality of channels running longitudinally through its internal space provides a passage for the electrical components to pass through. The inner cover is completely inserted into the outer cover. With such configuration, it is easy to assemble and to repair a lamp holder without damaging any of its parts. In addition, an annular groove into which a neck of the lamp cover is mounted is provided, such that any kinds of lamp cover with a suitable neck size can be fitted thereto.
