Fired-up type, source of illumination (7)

Ross

I believe the answer is:

kindled

'fired-up' is the definition.

'type source of illumination' is the wordplay.
'type' becomes 'kind' (I've seen this before).
'source of illumination' becomes 'led' (light emitting diode).
'kind'+'led'='KINDLED'

(Other definitions for kindled that I've seen before include "was inspiring" , "Set on fire" , "Inspired" , "Awoken" .)

I've seen this clue in The Times.
