Abstract: A medical examining lamp includes a first tubular standard mounted on a base and extending upwardly therefrom and a second tubular standard telescopingly received within the first standard and having a lamp socket mounted at its upper end. A spring assembly is mounted on the lower end of the second standard and includes first and second leaf springs mounted in and diverging outwardly from one end of the second standard. The leaf springs are retained in position by deforming the end of the second standard inwardly into engagement therewith. An arcuate tip is formed on the outer end of each leaf spring for resilienly engaging the inner surface of the first standard.
