Abstract

A portable high intensity lamp comprising of a housing having a lamp supported in it and also carrying a battery and a switch relay and circuitry to energize and de-energize the light source from the battery, and a remote control trigger device and connecting line to the circuitry within the housing arranged to be removably supported in the housing, means being provided to hold the trigger device in the housing during transport, the trigger having a test and also an energize switch to operate the circuitry in the housing to thereby energize the light source, the test circuit being arranged to cause flow of current insufficient to actuate the switch relay but sufficient to test continuity of the line and establishment of correct operating conditions of the circuitry and light source prior to energization.

Dependent claims

A portable high intensity lamp comprising a housing, a lamp with a light source supported by said housing, a battery in said housing to energize the light source of said lamp, a switch relay in said housing to energize and de-energize said light source, circuitry within said housing to activate said switch relay under remote control, and a remote control trigger device and connecting line to said circuitry within said housing but itself arranged to be remotely removably supported in said housing, means to hold said trigger device in said housing during transport, circuit closing means in said trigger device to energize said switch relay through said circuitry in said housing to thereby energize said light source, and test means in said trigger device to cause flow of current insufficient to actuate said switch relay but sufficient to test continuity of said line and establishment of correct operating conditions of said circuitry and light source.
