Abstract

A lamp includes a tubular glass bulb with open end sides, at least one elongate carrier, inserted into the glass bulb, for at least one light strip, at least one elastic diffuser layer which is introduced into the glass bulb, and two bases which are fitted onto the open end sides of the glass bulb. The at least one light strip has a strip-shaped circuit board with a front-side conduction structure and with at least one semiconductor light source which is electrically connected thereto. The conduction structure is electrically connected to at least one of the bases. The at least one diffuser layer arches over the at least one semiconductor light source and the at least one conduction structure in a contact-free fashion at least over a length between the bases. The at least one diffuser layer is latched to the at least one carrier.
