A light fixture has a translucent tubular bulb. At least one end cap is located at one end of the translucent tubular bulb. A light engine is disposed in the translucent tubular bulb. The light engine has a leadframe on which a plurality of semiconductor light elements is arranged. The fixture may include an electronic driver. The electronic driver includes a plurality of electronic components. At least one of the plurality of electronic components is arranged inside the transparent tubular bulb.

Tube lamp with leadframe

A light fixture for an LED lamp having a glass bulb and at least one light-emitting diode. The glass bulb is filled with a heat-conducting gas and the at least one light-emitting diode is arranged inside the glass bulb. The heat-conducting gas in the glass bulb has a pressure of at least 2.2 bar at room temperature.

Illuminant for an LED lamp, and LED lamp

An LED light fixture includes a glass bulb. In the interior of the glass bulb is a driver module and a plurality of lighting elements. The glass bulb completely surrounds the lighting elements radially. The lighting elements are arranged radially around the driver module. The lighting elements may be LED filaments or individual light-emitting diode chips.

Lamp with radial mounted COB LED and integrated electronics

A LED module for use in a LED light, preferably a LED retrofit lamp, has a leadframe and one or more LEDs which are electrically and mechanically connected to the leadframe. The LED module has one or more stabilizing sections made from an insulating material which are introduced locally, preferably in a punctiform and/or linear manner, into intermediate spaces of the leadframe in order to fasten sections of the leadframe to one another and, preferably, to space them apart from one another.

LED module with a stabilized leadframe

In various embodiments, a lamp has a bulb with a pinch seal, which holds a light-emitting element by means of a wire clip. The wire clip consists of tungsten and has, at an end remote from films embedded in the pinch seal, an eyelet for holding the light-emitting element. An end of the wire clip which is close to a film is bent back. A film associated with the wire clip is folded in a roof-shaped manner. Overall, it is thus possible to realize a lamp with a long life.
