## Abstract

In various embodiments, a lighting device is provided. The lighting device may include at least one first part and at least one second part, fastened to the first part, which first and second parts are interconnected by a potting compound, the parts being positively interconnected by the potting compound.

## Claims

### Claim 1

A lighting device, comprising:
at least one first part and at least one second part, fastened to the first part, which first and second parts are interconnected by a potting compound, the parts being positively interconnected by the potting compound.

### Claim 2 (depends on 1)

The lighting device of claim 1,
wherein the lighting device is a semiconductor lighting device

### Claim 3 (depends on 1)

The lighting device of claim 1,
wherein the first and second parts are interconnected by a curing adhesive substance.

### Claim 4 (depends on 1)

The lighting device of claim 1,
wherein at least one of the parts has at least one undercut that is at least partially embedded in the potting compound.

### Claim 5 (depends on 1)

The lighting device of claim 1,
wherein at least one of the parts has at least one recess that is filled with the potting compound.

### Claim 6 (depends on 5)

The lighting device of claim 5,
wherein the recess is formed as a constriction.

### Claim 7 (depends on 1)

The lighting device of claim 1,
wherein at least one of the parts has at least one projection protruding into the potting compound.

### Claim 8 (depends on 1)

The lighting device of claim 1,
wherein at least one of the parts has a periphery formed as a bead.

### Claim 9 (depends on 8)

The lighting device of claim 8,
wherein the bead is embedded in the potting compound.

### Claim 10 (depends on 1)

The lighting device of claim 1,
wherein at least one of the parts has a peripheral region that is curved in profile, which is at least partially embedded in the potting compound.

### Claim 11 (depends on 1)

The lighting device of claim 1,
wherein the lighting device is a tubular retrofit lamp, a first part being formed as a long light-transmissive bulb and an end cap is formed at at least one end of the bulb as the second part.

### Claim 12 (depends on 11)

The lighting device of claim 11,
wherein the bulb has a constricted end region with a reduced cross section, which is covered by the end cap, and the constriction is filled with the potting compound.

### Claim 13 (depends on 1)

The lighting device of claim 1,
wherein the lighting device is an incandescent retrofit lamp and the first part is formed as a light-transmissive bulb, a base part being formed on a periphery of the bulb as a second part.

### Claim 14 (depends on 1)

The lighting device of claim 1,
wherein a base material of the parts is differing.

### Claim 15 (depends on 1)

The lighting device of claim 1,
wherein one of the parts is a glass part and another of the parts is a non-glass part.
