- circuit board has an electronic circuit, in particular at least one integrated circuit and / or at least one SMD component, for driving the light-emitting diodes.
- This also advantageously simplifies conventional signal lamps, since they themselves have no control electronics or only one very trivial, such as on / off switches, which makes them inexpensive to manufacture.
- the light-emitting diode is expediently a white or colorless and / or colored LED.
- An all-round lighting effect is achieved in that several light-emitting diodes are arranged on the circuit board in such a way that they emit electromagnetic waves in the visible spectral range in at least four different directions with respect to the circuit board. This simulates in a particularly advantageous manner a lamp with a glass bulb that emits all around.
- the radiation directions are expediently perpendicular to one another.
- a high or desired luminosity per direction of radiation is advantageously achieved in that at least two light-emitting diodes are provided for each direction of radiation.
