Light output of fluorescent lamps automatically held constant by means of peltier type coolers

Claim 1

IN A LUMINAIRE HAVING AT LEAST ONE FLUORESCENT LAMP THE LIGHT OUTPUT OF WHICH IS OPTIMUM AT A PREDETERMINED LAMP BULB TEMPERATURE AND WHICH DIMINISHES AT TEMPERATURES ABOVE SAID PREDETERMINED TEMPERATURE, THE COMBINATIONS WITH SAID LAMP OF MEANS ADJACENT A LOCALIZED PORTION OF SAID LAMP FOR COOLING AND MAINTAINING SAID LOCALIZED PORTION AT SAID PREDETERMINED TEMPERATURE; SAID MEANS COMPRISING A PLURALITY OF RELATIVELY SPACED HEAT ABSORBING SHOES ADJACENT A LOCALIZED PORTION OF SAID LAMP AND RECEIVING HEAT THEREFROM, A HEAT DISSIPATING MEMBER SPACED FROM EACH OF SAID HEAT ABSORBING SHOES, A PAIR OF PELTIER-TYPE JUNCTIONS CONNECTING RESPECTIVE ONES OF SAID HEAT ABSORBING SHOES AND HEAT DISSIPATING MEMBERS, A SOURCE OF ELECTRICAL ENERGY, SAID PELTIER-TYPE JUNCTIONS, HEAT ABSORBING MEANS, HEAT DISSIPATING MEMBERS AND SAID SOURCE OF ELECTRICAL ENERGY BEING SO INTERCONNECTED THAT WHEN AN ELECTRIC CURRENT IS PASSED THROUGH SAID PELTIERTYPE JUNCTIONS HEAT IS TRANSFERRED FROM SAID HEAT ABSORBING SHOES TO SAID HEAT DISSIPATING MEMBERS, AND MEANS CONTROLLED BY THE TEMPERATURE OF SAID LOCALIZED PORTION AND CONNECTED TO SAID SOURCE OF ELECTRICAL ENERGY FOR CONTROLLING THE AMOUNT OF SAID HEAT TRANSFER IN ACCORDANCE WITH THE TEMPERATURE OF SAID LOCALIZED PORTION, SO THAT SAID LOCALIZED PORTION IS MAINTAINED AT SAID PREDETERMINED TEMPERATURE AND LIGHT OUTPUT OF SAID LAMP IS MAINTAINED AT OPTIMUM.
