What makes a lamp directional?


Expert Answer

Step 1

Directional lamps are the lamps that emit lights in a specific direction. LED’s are the example of the directional lamp. They emit light only for 1800 . Hence,  all the light can be directed to a specific direction or spot.

Step 2

An LED lamp is a semiconductor device when electrons pass through the junction, a photon is emitted. ...
