Abstract
Abstract A lamp assembly comprises a lamp housing having a removable top cover and a removable end cover. A pair of cradle arrangements are contained in the lamp housing. One of the cradle arrangements comprises two individual lamp cradles, while the other cradle arrangement comprises three individual cradles. The cradle arrangements may be removed from the lamp housing by removing the top cover or, alternatively, by removing the end cover. Each of the individual cradles has an ultra violet lamp mounted thereon. When the cradle arrangements are positioned in the lamp housing, the individual cradles are disposed successively along a common axis but in a staggered fashion with respect to the common axis. The cradles are arranged so that the individual lamps are substantially parallel to the common axis and so that the ends of neighbouring cradles overlap each other. It is thus possible to achieve a relatively long light source using relatively short lamps. An end of each lamp is releasably held by a holder mounted on the associated cradle.

Claim 10
Dependent Claim
89 words
A lamp assembly comprising: a cradle housing having a removable end cover and at least one further removable cover; at least two cradles contained in said cradle housing; and an individual elongate lamp mounted in each cradle; the individual cradles being disposed successively along a common axis but in a staggered fashion with respect to said common axis, the cradles being arranged so that the individual lamps are substantially parallel to the common axis, and the cradles being arranged so that the ends of neighbouring cradles overlap each other.
Claim 11
Dependent Claim
163 words
A lamp assembly comprising; a cradle housing; at least two cradles contained in said housing; and an individual elongate lamp mounted in each cradle; the individual cradles being disposed successively along a common axis but in a staggered fashion with respect to said common axis, the cradles being arranged so that the individual lamps are substantially parallel to the common axis, and the cradles being arranged so that the ends of neighbouring cradles overlap each other; each cradle having a lamp holder at each end thereof and, in each cradle, at least one lamp holder comprising: a first plate secured to the cradle; a first insulator carried by the first plate; a second plate; means for releasably securing the second plate to the cradle; and a second insulator carried by the second plate; said first and second plates together with said first and second insulators being arranged to cooperate with each other to hold the end of a lamp mounted on the holder.
Claim 12
Dependent Claim
163 words
A lamp assembly comprising; a cradle housing; at least two cradles contained in said housing; and an individual elongate lamp mounted in each cradle; the individual cradles being disposed successively along a common axis but in a staggered fashion with respect to said common axis, the cradles being arranged so that the individual lamps are substantially parallel to the common axis, and the cradles being arranged so that the ends of neighbouring cradles overlap each other; each cradle having a lamp holder at each end thereof and, in each cradle, at least one lamp holder comprising: a first plate secured to the cradle; a first insulator carried by the first plate; a second plate; means for releasably securing the second plate to the cradle; and a second insulator carried by the second plate; said first and second plates together with said first and second insulators being arranged to cooperate with each other to hold the end of a lamp mounted on the holder.
