Abstract
A waterproof socket-type halogen lamp for a livestock barn comprises a fixing body forming a hollow part, a side plate finishing the outside of the fixing body, a contact point, a wire, an annular insulator insulating the fixing body, a spring which is embedded in the hollow part and of which an outer side is supported by the side plate, an inner side supports the outer side of the annular insulator to provide restoration force while supporting one terminal of the tube halogen lamp through the contact point, and an inner waterproof packing which prevents moisture or dust from penetrating to the inner end of the fixing body and has a closed curve shape with a terminal passing groove through which a lamp terminal housing passes, and a tube halogen lamp in which lamp terminals at both ends are connected with the contact point by two socket parts.
