A little more info about what you do and what you expect
would be appreciated ;-)
I assume you use the "-l" option as Justin Hadella mentioned.
Note that light sources are invisible in POV, see below.

4.5.5.6 Looks_like
Normally the light source itself has no visible shape.
The light simply radiates from an invisible point or area.
You may give a light source any shape by adding a
"looks_like { OBJECT }" statement. There is an implied
"no_shadow" attached to the "looks_like" object so that
light is not blocked by the object. Without the automatic
"no_shadow" the light inside the object would not escape.
The object would, in effect, cast a shadow over everything.
If you want the attached object to block light then you
should attach it with a union and not a looks_like as follows:
union {
light_source { <100, 200, -300> color White }
object { My_Lamp_Shape }
}
Presumably parts of the lamp shade are transparent to let some light out.
