Morphology
The meaning is directly derivable from combining 'carbon' + 'arc' + 'lamp': it denotes a lamp that produces light via an electric arc involving carbon electrodes.

Etymology
Carbon arc lamp gets its name from a simple picture: two carbon rods with a bright arc of electricity jumping between them inside a lamp, which makes very strong light. So the name means a 'lamp' where a bright arc between carbon rods makes the light.
