Problems solved by technology

In addition, due to the electric power limit on the EVG side, the 35-watt T5 fluorescent tube is not working at its rated power, but not at full load, so compared to normal operation, the service life of the T5 fluorescent tube is significantly shortened

Embodiment Construction

[0030] According to the figures, the adapter assembly according to the invention comprises an EVG housing 1 with contact pins designed as sockets for T8 fluorescent tubes and soldered on a sub-circuit board 7d.

[0031]An EVG electronic component 7 with circuit boards (printed circuit boards) 7a, 7b, 7c, 7d and flexible strips 7e is supported on the circuit board holder 2, wherein the flexible strips 7e form a gap between the individual circuit boards 7a, 7b, 7c, 7d. electrical contact. The printed circuit board holder 2 together with the EVG electronics 7 is now inserted into the interior of the EVG housing 1 and locked there. The front free tip of the mounting finger 2a is used to allow the circuit board 7d with the two contact pins 1a for the T8 socket to be moved into the interior of the EVG housing 1 in a positionally correct and problem-free manner and fixed there. , the contact pin 1 a moves through the opening in the end side of the EVG housing 1 .

Abstract

An adapter set for fluorescent lamps with electronic ballast for converting to a fluorescent tube having a smaller diameter. The electronic ballast and the end cap adapter each on one axial front thereof comprise contact pins having dimensions of fluorescent tubes of larger diameters, and on the opposite axial front have contact sockets for receiving two contact pins of the fluorescent tube having a smaller diameter. Preferably, the electronic components of the ballast are located on at least two spatially separated partial circuit boards which may be connected to each other by a flexible contact strip. A jacket tube has at least one cable channel that extends axially relative thereto to house the wiring connecting the contact pins of the end cap adapter and the electric ballast.

Description

technical field [0001] The present invention relates to an adapter assembly for retrofitting (using) a fluorescent lamp to a smaller diameter fluorescent tube with EVG (Electronic Ballast). [0002] In particular, the invention relates to a lighting system for retrofitting T8 / T12 fluorescent lamps into modern and energy-saving T5 fluorescent tubes with EVG. Background technique [0003] Such fluorescent tubes are straight, double-ended fluorescent tubes which can be inserted (first inserted and then rotated) into two associated sockets on a fluorescent lamp holder (wall holder or cover holder). [0004] T8 fluorescent tubes refer to fluorescent tubes with a diameter of about 26 mm and with power-related lengths of about 590 mm, 1200 mm and 1500 mm, T12 fluorescent tubes refer to fluorescent tubes with a diameter of about 38 mm and with power-related lengths of about 590 mm, 1200 mm and fluorescent tubes with a length of 1500 mm, T5 fluorescent tubes refer to fluorescent tub...
