Abstract

In various embodiments, a lamp may include a lamp bulb composed of light-transmissive material; and at least one semiconductor light source arranged within the lamp bulb, and comprising a base, corresponding to a standardized incandescent lamp base; wherein the lamp has at least one optical waveguide which is connected to the lamp bulb and extends in the direction of the at least one semiconductor light source.

Claims

1. A lamp, comprising:

a lamp bulb composed of light-transmissive material; and

at least one semiconductor light source arranged within the lamp bulb, and comprising a base, corresponding to a standardized incandescent lamp base;

wherein the lamp has at least one optical waveguide which is connected to the lamp bulb and extends in the direction of the at least one semiconductor light source.

2. The lamp of claim 1,

wherein the optical waveguide has an optical waveguide section arranged within the lamp bulb and embodied in a light-scattering fashion.

3. The lamp of claim 2,

wherein the optical waveguide section embodied in a light-scattering fashion comprises at least one truncated-cone-shaped section whose truncated cone lateral surface is provided with a groove structure or is embodied in a step-like or staircase-like fashion.

4. The lamp of claim 2,

wherein the optical waveguide section comprises light-scattering particles or cavities or a roughened surface.

5. The lamp of claim 1,

wherein a first end of the optical waveguide terminates in a positively locking manner with a light-emitting surface of the at least one semiconductor light source.

6. The lamp of claim 1,

wherein a first end of the optical waveguide faces the at least one semiconductor light source and is embodied in a conical or truncated-cone-shaped fashion.

7. The lamp of claim 6,

wherein the first end of the optical waveguide is embodied in a light-scattering fashion.

8. The lamp of claim 1,

wherein a second end of the optical waveguide is connected to the lamp bulb.

9. The lamp of claim 1,

wherein the lamp bulb has a conical surface structure in the region of connection to the optical waveguide.

10. The lamp of claim 1,

wherein the optical waveguide is shaped from the material of the lamp bulb.

11. The lamp of claim 1,

wherein the base has a reference plane with respect to which the spatial position and alignment of the first end of the optical waveguide are adjusted.

12. The lamp of claim 11,

wherein the first end of the optical waveguide is arranged at a distance from the reference plane which corresponds to the distance between the incandescent filament and the reference plane in the case of a compatible incandescent lamp.

13. The lamp of claim 1,

wherein components of an operating device for the at least one semiconductor light source are arranged in the base.
