Problems solved by technology

The problem with these types of lamps is that they are relatively poorly packed, especially during storage and transport of these lamps, as the laterally extending electrodes require a considerable distance between the lamps
This results in a relatively large, and thus relatively inefficient, lamp package in which a relatively large amount of space is left unused
The known bulky packaging of light sources often results in a great deal of waste in the storage and transport of these light sources

Embodiment Construction

[0016] Figure 1a is a perspective view of a part of a lamp 1 known in the prior art. The lamp 1 comprises a discharge vessel 2 filled with an ionizable substance, at the ends of which two end caps 3 are provided (only one end cap 3 is shown in the figure). The lamp 1 also comprises two electrodes 4 connected to opposite sides of the discharge vessel 2 . Each electrode 4 is partially embedded in a kind of end cap 3, the two contact elements 5 of each electrode 4 extending laterally with respect to the discharge vessel 2 (and these end caps 3), which makes the lamp 1 ideally suited for backlighting Purpose.

[0017] Fig. 1b is a side view of the assembly 6 of the lamp 1 according to Fig. 1a in a packaged state. As can be seen from this figure, due to the laterally extending contact elements 5 of the electrodes 4 , the lamps 1 are packaged in a relatively large volume. The distance D between the discharge vessels 2 is relatively large, since physical contact between the contac...

Abstract

The invention relates to a light source comprising: an at least partly light- transmitting elongate discharge vessel filled with an ionizable substance, at least one first electrode and at least one second electrode connected to respective end portions of the light source, between which first and second electrodes a discharge extends during lamp operation, at least one electrode of the first electrode and the second electrode extending laterally with respect to the corresponding end portion. The invention also relates to an assembly of light sources according to the invention.

Description

technical field [0001] The invention relates to a light source comprising: an at least partially light-transmissive elongated discharge vessel filled with an ionizable substance, a first electrode and a second electrode, the first electrode and the second electrode being respectively connected to terminals of the light source The end portion, during operation of the lamp, the discharge extends between the first electrode and the second electrode, whereby at least one of the first electrode and the second electrode extends laterally with respect to the corresponding end portion. The invention also relates to an assembly of a light source according to the invention. Background technique [0002] Known display devices such as LCD image screens generally require a backlighting of the entire surface area of ​​these devices which is as uniform as possible in order to present a viewable image. A lamp according to the preamble is often used for this purpose, wherein both electrodes...
