Semiconductor incandescent lamp retrofit lamp
View Patent ↗A semiconductor incandescent lamp retrofit lamp may include: at least one semiconductor light source, at least one light scattering body, and at least one optical waveguide, into which light of the at least one semiconductor light source can be coupled, wherein the at least one light scattering body is configured and arranged for the purpose of diffusely emitting light supplied thereto from the at least one semiconductor light source by way of the at least one optical waveguide.
1. A semiconductor incandescent lamp retrofit lamp in a form of a vehicle headlight lamp, comprising:
a bulb disposed above the base of the semiconductor incandescent lamp retrofit lamp;
at least one semiconductor light source housed within a base of the semiconductor incandescent lamp retrofit lamp,
two light scattering bodies disposed above the at least one semiconductor light source,
a framework disposed above the at least one semiconductor light source and adjoined to the base in the direction of a longitudinal axis of the incandescent lamp retrofit lamp; said framework having two sockets arranged and spaced apart along the longitudinal axis; wherein the sockets accommodate one of said light scattering bodies, and
at least one optical fiber adjoined to a corresponding light emission surface of the at least one semiconductor light source, which leads from to the light scattering bodies to the at least one semiconductor light source, and into which light of the at least one semiconductor light source can be coupled therein,
wherein each of the two light scattering bodies is a roughened substantially cylindrical body made of glass or polymethyl methacrylate(PMMA) to diffusely emit light supplied from the at least one semiconductor light source by way of the at least one optical fiber through the bulb, and
wherein a driver for powering the at least one semiconductor light source is housed within the base.
2. The semiconductor incandescent lamp retrofit lamp as claimed in claim 1 , having an additional fiber, which leads from a respective light scattering body to a semiconductor light source assigned to the respective light scattering body.
3. The semiconductor incandescent lamp retrofit lamp as claimed in claim 1 , wherein the sockets are terminal sockets.
4. The semiconductor incandescent lamp retrofit lamp as claimed in claim 1 , wherein at least one semiconductor light source comprises at least one light-emitting diode.
5. The semiconductor incandescent lamp retrofit lamp as claimed in claim 1 , wherein a cover cap partially surrounding one of the light scattering bodies is fixed to the framework.
