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.

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.
