This is a charade - two separate parts are joined together to form the answer. Look for words or abbreviations that can be combined.
The first part comes from 'light' - think of the abbreviation for light-emitting diode. The second part is 'aircraft' - specifically a type of German airship. Join these together.
Answer: LED ZEPPELIN | L.E.D. (abbreviation for light-emitting diode) + ZEPPELIN (type of aircraft/airship) = LED ZEPPELIN (famous rock band)
