A lamp includes a base, a light-permeable bulb containing at least one light source, and a driver for powering the light source. The driver is located within the base. The bulb has outwardly leading supply lines on the base side, and the driver has at least one contact element which projects in the direction of the bulb into which a free-standing section of the respective supply line is inserted to make contact. The technology is particularly applicable to lamps with LEDs as light sources, in particular for replacement of conventional lamps such as incandescent lamps.

Lamp

A lighting device includes a translucent bulb and a light engine arranged in said bulb. The bulb comprises a base with two connection wires for connecting the light engine. The light engine comprises two connection elements which are electrically and mechanically connected to the connection wires. The connection elements each comprise a gripping region for holding the light engine and a connecting region for connecting the light engine to the connection wires.

Lighting device with improved connection to the power supply

A lighting device comprises a holder for LED filaments. The holder has a first electrically conductive holding structure and a second electrically conductive holding structure. Each holding structure comprises an essentially longitudinal connection section and an attachment section essentially perpendicular to the connection section.
