'very pleased' is the definition.
(I've seen this before)

'with the lamp indeed' is the wordplay.
'with' indicates putting letters inside.
'the lamp' becomes 'light' (I've seen this before).
'indeed' becomes 'deed' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'light' put inside 'deed' is 'DELIGHTED'.

Can you help me to learn more?

(Other definitions for delighted that I've seen before include "Over the moon" , "Happy" , "Greatly pleased" , "Joyful" , "Pleased as Punch" .)
