There's no difference. The LED lamp is a semiconductor lamp, because it is a light-emitting diode, and the diode is a semi-conductor.

There may be a variety of semiconductors, it includes LED lights, is a large class. LED lights use a constant current drive, and the light emitted is much more stable than ordinary bulbs.

The difference between semiconductor lights and led lights
< br >
The first LED lamp belongs to a kind of semiconductor lamp, but it is not completely semiconductor, it can only be said that semiconductor chips, semiconductor lamps are a wide variety, the most common is light-emitting diodes, the color of light is red, green, etc., used as electronic components.

The second LED lamp is a constant current drive, the light is similar to daylight, white light, there is no flicker phenomenon, and it has a certain protective effect on the eyes.
A semiconductor is a material whose electrical resistivity is between a metal and a non-metal and has good electrical conductivity and isolation properties. LED (light emitting diode) is an electronic device that uses semiconductor materials to convert electrical energy into light energy, and different wavelengths of light such as visible and infrared light appear. Therefore, LED is a light source manufactured by semiconductor technology, and its biggest characteristics are high efficiency, energy saving, long life, and not easy to damage. The application range of semiconductors is more extensive, in addition to LED, but also used in electronic devices, solar cells, sensors and other fields.
Semiconductor is a general term for materials, and led is a light-emitting element in a semiconductor.
