A bit of blood, as lamp got broken (6)

Ross

I believe the answer is:

plasma

I'm a little stuck... Click here to teach me more about this clue!

'a bit of blood' is the definition.
'plasma' can be an answer for 'blood' (thesaurus). I'm unsure of the 'a bit of' bit.

'as lamp got broken' is the wordplay.
'as lamp' anagrams to 'PLASMA'.
Though, I am not sure how this is indicated.

Can you help me to learn more?

(Other definitions for plasma that I've seen before include "Colourless fluid in which blood cells are suspended" , "Part of blood; ionised material" , "Colourless fluid of the blood and lymph" , "Blood component and type of television" , "Star material" .)
