(54) Lighting unit


(57) A solid state lighting unit (100). The lighting unit (100) includes a lens device (104), at least one solid state lighting device (106,108), and a heat sink (112). The lens device (104) and the heat sink (112) are push fit coupled directly together in manner such that the solid state lighting device (106,108) is held in thermal contact with the heat sink (112) thereby enabling, in use, at least some of the heat generated by solid state lighting device (106,108) to be transferred to the heat sink (112) by conduction.
A method of manufacturing a lighting unit (100) is also disclosed.
