Embodiment Construction

[0033] The inventive idea of ​​the present invention is that the retrofit lighting system can be equipped with the actual filament unit, basically in the form of a discrete component designed to be coupled with the connection pins of the lighting system. In order to improve its compatibility with existing electronic ballasts, the lighting system may be provided with at least one such filament unit, or the filament unit may be provided to be coupled to an existing lighting system. In the following, different embodiments of a lighting system according to an aspect of the present invention and embodiments of a filament unit are described.

Abstract

The invention relates to a light emitting device (2) for retrofitting a fluorescent lamp comprising two sets of connecting pins (21, 23, 21', 23') for connecting the light emitting system (1) to a lighting fixture, one first (611) and one second (613) filament unit, encapsulated in a bulb and fed through it, electrically coupled to the connecting pins (611, 613) and a solid state light source connected between the filament units.

Description

technical field [0001] The present invention relates generally to a lighting system, and more particularly to a light emitting diode (LED) lamp which can be compatible retrofitted to various lamps with ballasts, especially high frequency (HF) ballasts Lighting fixtures. Background technique [0002] LEDs are playing an increasingly important role in general lighting applications. Therefore, more and more new devices are equipped with LED light sources in various ways. The reason for replacing existing light sources with LED light sources is that LED light sources have low power consumption and extremely long life. Furthermore, the lifetime of a corresponding housing for accommodating the fluorescent light source and a corresponding driver for powering the fluorescent light source are considerably long compared to, for example, the lifetime of the fluorescent light source. Therefore, it seems attractive if the user can simply replace such fluorescent light sources. [000...
