Abstract: A connecting element for connecting at least two rails adapted for mounting semiconductor light sources. The connecting element has a bottom wall and two side walls emerging from the bottom wall on opposite sides. The walls form a U-shaped profile. The connecting element is configured for accommodating at least one rail adapted for mounting semiconductor light sources in an accommodating area delimited by the bottom wall and the side walls, and the connecting element has latching elements arranged with a regular longitudinal pattern on at least one wall for latching with the accommodated rail.

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.
