Abstract: An end cap for a retrofit LED lamp includes a transparent tube. An end cap is mounted to an end of the transparent tube. A pair of pins electrically and mechanically connects the LED lamp to a tube holder. The pair of pins extends through the end cap. A protective cap sits over the pair of pins thereby protecting the pair of pins from being touched by a user.

Abstract: A connection module for a lamp, preferably an LED-based filament lamp, having an on-board antenna, a driver for supporting such connection module, and a corresponding lamp having such connection module. Accordingly, a connection module for a lamp having a bulb and a base is suggested, preferably for an LED-based filament lamp, including a first side configured to be received by a driver in the base of the lamp and a second side including an elongate region extending towards the bulb of the lamp. The elongate region has a width smaller than a length of the second side and first side, and an antenna. The antenna is integrated in the connection module on the elongate region.

Abstract: A disconnector for an electric circuit having a first electrical contact and a second electrical contact for connecting or disconnecting an electric circuit connected to the first electrical contact and the second electrical contact. Each of the contacts have a first end with a base contact and a second end with a contact point for electrically connecting the first electrical contact to the second electrical contact. The disconnector has a isolating support for supporting the first electrical contact and the second electrical contact such that the first electrical contact is in touch with the second electrical contact at the contact points in a mechanically pre-loaded condition to connect the electric circuit electrically. The first electrical contact and the second electrical contact can be separated by a separator plate.

Abstract: An LED lighting device includes a housing, an LED light-emitting unit arranged inside the housing, and an LED driver configured to drive the LED light-emitting unit to operate. The LED driver and the LED light-emitting unit are integrally arranged inside the housing. The LED lighting device allows the number of components to be reduced, and the structure to be more compact, thus allowing the LED driver to be set inside a housing of a small lighting device.
