An electric lamp comprises a lamp base and an envelope having a common axis, a support member having a fixing gap around the common axis, and an elastic shade of substantially conical shape. The shade has a first end portion inserted in the fixing gap and a second end portion remote from the lamp base. The diameter of the first end portion taken perpendicularly to said axis is smaller than the diameter of the second end portion, and the elastic shade is made of heat resistant plastic foil.
