BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a light emitting diode lamp, and more particularly, to a light emitting diode lamp assembly including a light emitting diode (LED) as a light source, which is a semiconductor device that emits light when a current flows through a compound.

When a current flows through a compound such as gallium arsenide, it emits light. The light can be obtained using this principle, called a light emitting diode (LED). It is used as a lamp of a large display board installed and a lamp that sends a light signal to the TV main body when the TV remote control button is pressed.

As described above, the light emitting diode (LED) has a structure in which positive charge particles, called electrons and holes, are combined at the center of the electrode to emit light photons when a current passes through a conductive material attached to an electrode on the bottom.
