摘要：A battery-powered lamp has a box-like casing with a top and side walls forhousing at least one battery. At least one of the side walls has a depression whichprovides a generally planar depressed portion having an opening therethrough. A lightsource is supported in the casing. A lens, through which light from the light source can betransmitted, lens has a peripheral rim which is a friction fit in the opening. On itsperipheral rim it has a plurality of ratchet-like teeth mutually spaced around the lensperiphery. They make snap fits with and locate behind the material of the side wallbounding the opening so as to resist lens removal. Outside the peripheral rim of the lensis a surrounding flange which limits the depth of insertion of the lens in its opening. Theside wall bounding the opening has a plurality of spaced notches which register with thelens teeth to prevent rotation of the lens relative to the opening. The lens teeth aretriangular in configuration and are integral with the lens rim. Two opposite side wallseach has a depression in which an opening is disposed. The lens is a friction fit in each ofthe openings.
