Embodiment Construction
[0011] figure 1 A schematic cross-sectional view of a preferred embodiment of a lamp assembly with an internal light absorbing coating is shown. A preferred PAR lamp assembly 10 includes a light source 12 having two sealed electrodes 14 , 16 defining a lamp axis 18 ; a concave ceramic envelope 20 having an internal reflective surface 22 . The housing 20 also has a neck 24 defining a neck cavity 26 and a reflector axis 28 . The neck 24 is provided with electrical connections 30 and mechanical support for the light source 12 . Housing 20 surrounds light source 12 to reflect light from light source 12 to the area to be illuminated during operation of the lamp. Preferably the light source 12 and reflector 20 are oriented such that the lamp axis 18 is substantially coaxial with the reflector axis 28, and at least a portion of at least one of the electrodes 14, 16 extends in the neck cavity 26, and an area With a substantially non-transmissive light-absorbing layer 32 .
