Nozzle mounted lamp
First Claim
1. A lamp for a nozzle comprising:
- a housing having an outer peripheral wall and an inner peripheral wall, the inner peripheral wall defining a central cavity extending through the housing, the central cavity lying along a central axis and enabling the housing to be mounted circumferentially around the nozzle;
a securing device connected to the housing for securing the housing to the nozzle;
a lighting unit positioned within the housing and encircling the central cavity;
a first lens positioned over the lighting unit, the first lens having an outer periphery and an inner periphery, the inner periphery defining a central opening through the first lens;
a retaining member for securing and sealing the outer periphery and inner periphery of the first lens to respective outer and inner peripheral walls of the housing to hermetically seal the lighting unit within the housing; and
a second lens positioned over the first lens for protecting the first lens, the second lens having an outer periphery and an inner periphery, the inner periphery defining a central opening through the second lens.

Abstract
A lamp for a nozzle includes an annular housing having an outer peripheral wall and an inner peripheral wall, the inner peripheral wall defining a central cavity extending through the housing. The central cavity lies along a central axis and enables the housing to be mounted circumferentially around the nozzle. A securing device is connected to the housing for securing the housing to the nozzle. A lighting unit is positioned within the housing and encircles the central cavity. An annular shaped first lens is positioned over the lighting unit. A retaining member secures and seals the first lens to the outer and inner peripheral walls of the housing for hermetically sealing the lighting unit within the housing.
