The invention relates to a light emitting device, in particular a traffic signal light emitting device, which is composed of light emitting diodes (LEDs). Said device is characterised by (a) a support body comprising a mounting zone for fixing the light emitting device in a socket that supplies power to the latter and a light emitting zone that is equipped with LEDs; b) and a printed circuit board or a sandwich-type printed circuit board assembly, on which the LEDs and the components of one circuit are mounted, said circuit permitting the connection of the light emitting device to a line voltage of at least 110 V, without a voltage conversion. |
