- a control electronics for example, a driver circuit
- Application examples can also be used several individual conductor wires, which are placed side by side.
- the (releasable) contacts can be designed as piercing contacts or as cutting contacts (IDC). It is possible that at least a part of the (releasable) contacts as cutting contacts (IDC) and at least a part of the (releasable) contacts is designed as piercing contacts.

- the chip-on-board (COB) technology enables a very close assembly of light-emitting diodes , whereby a very homogeneous light distribution can be achieved when placing groups of light emitting diodes.
- the LEDs 1, 2 and 3 may consist of a LED semiconductor chip, which can be covered by a potting compound.
- This lenticular potting compound which is advantageously very transparent, on the one hand protects the LED semiconductor chips and on the other hand acts as a lens 5 in order to align and optimally extract the light radiation emitted by the LED semiconductor chips.
- This potting compound lens 5 is generally referred to as the primary optic of the light emitting diode.
- the lens 5 may be formed as at least one globe top.
- the potting compound has a lens effect and may also contain a color conversion substance. By way of example, the color conversion substance converts the light of a blue LED semiconductor chip into white light.
- a fastening part 13 can be attached, which can be used either with a rail 18 or for attachment to fastening ropes 12.
- circumferential sealing lips 14 are mounted so that the contacting of the ribbon cable 9 is protected against ingress of moisture.
- penetration of moisture into the lamp can be prevented and thus a bulb of protection class IP65 can be produced.
- Ingress of moisture could, for example, lead to a short circuit in the luminous means or else to accelerated aging of the light-emitting diodes.
- the lower part can be hung on one side in the housing 7 and screwed on the opposite side by means of the fixing element 11 with the housing 7.
- the fixing element 11 may be, for example, a screw.

- the web 17 on the underside of the housing 7 may be formed so that it cuts through the ribbon cable 9 at least a portion of the conductor of the ribbon cable 9 and thus interrupts when contacting.
- the light source can be opened so that an exchange of the carrier element 4 with the LEDs 1,2,3 and a renewed contact with the ribbon cable 9 is possible.
- the carrier element 4 advantageously has a high thermal conductivity in order to effectively dissipate the heat generated by the light-emitting diodes 1 and 2 and to keep the temperature of the LED semiconductor chips as low as possible.
- the support member 4 may be at least partially formed as a reflector in order to achieve a better Lichtauskoppelung by the light emitting diodes 1 and 2.
- the support member 4 may consist of a
