This invention relates to an improvement in illuminating devices for refrigerators, dis-.

play cases and the like and has for its primary objectthe purpose of, providing im-- 5 proved means adjacent the illuminating element whereby theheat caused by the element will not be effective inwardly of the refrigg ogf jv le dgesjl5 each ledgesbeing securedion a erator. g 7

Another object of the inventlon is in prom Viding an improvement in the housing of the illuminating element of the refrigerator whereby the heated air surroundin the element will be discharged from the housing thereby preventing heat being projectedinto 1 the refrigerator, I Other and further objects-will appear in the specification and bespecifically pointed out in the appended claims, reference be ing had in the'accomp'anying drawings, ex-

: emplifying theinvention, and in which Figure 1 1s a vertical transverse section taken through the upper portion of a refrig erator show case'showing this improved illuminating device and housing therefor;

2; Figure 2 is a fragmentary longitudinal section taken approximately on the line IIIIofF-ig. 1.

Figure 3 is a plan View of the cover plate I of the illuminating housing. a Referring by numerals to theaccompanying drawings 1 designates a portion of the front of a refrigerator show casehaving double glass walls 2 and adjoining said front portion 1 is the upper front rail 3 which forms part of the top 4 of the refrigerator,

the top 4 being ofthe usual construction of which glass forms the. major part thereof.

Transversely disposed in the top 4 between the front rail 3 and the rear rail 5is a com partment 6 having side walls which are formed of cross members 7 of the top 4, the

end walls of said compartment being provided by the front and rear rails 3 and 5 respectively, and formed in the front rail 3 1s a longitudinally extending bore or passageway 8 for the reception of electrical wlrlng 9.

MOuntedin the rail 3 transversely there-of is a bushing 10 which extends to the bore 8, said bushing being for the reception of a socket end 11 of an eleotriolamp bulb 12 partmen ue Qrae' p1 '1esa d hooid n i a dzs de m which the light emitted from the bulb 12 will direct \light rays fromthe bulb whi h i dj pose loas tud al ri r the 9m.-;

The channel 24 forms a down dra assageway -for air currents passing thea rtures 27. 7 From the escription ofthis invention it is obvious that a unique device is provided for eficiently carrying heated air from the light emitting element or bulb and in which the walls of the channels 19 and 24 as well as the bottom plates or glass panes 13 will be cooled by the fresh air currents being encured thereto intermediate of the width of aircurrents thereunder from thefirs't menterior of the deflector.

- 1 What I claim is i 1. A refrigerator show case or the like hav- 1 in a compartment formed in one of-its walls,

a ight emitting element located in said compertinent, a housing having opposing side portions overlapping said element, air en trainingpassageways leading to the underside of said side portions, and air escapement means leading from the top of said housing 2. A refrigerator orthe like having a'compartment formed in one of its walls, a light emitting element located in said compartment, a closure late for said compartment, a housin depen ed from said plate mounted over sai element, a down draft passageway compartment.
