Fluid transfer device and apparatus including such a device

Abstract

The invention relates to a device for transferring fluid between two separate structures (5, 7) including a rigid pipe with a double shell extending along a longitudinal axis (x), the pipe including an outer shell (2) housing, in the inner vacuum space thereof, at least one inner duct (3) for fluid transfer, the pipe including, at a first end, a first rigid connection (4) of the outer shell (2) to the first structure (5) and, at a second end, a second rigid connection (6) of the outer enclosure (2) to the second structure (7), the first and second ends of the outer shell (2) being rigidly connected to the at least one inner duct (3), the pipe comprising a system to compensate for movements, including at least one flexible area (13, 14) and at least one resilient area (10, 11, 30), in the longitudinal direction (x), the system to compensate for shifts also including a connection (12) which slides along the longitudinal axis (x) between the outer shell (2) and the first structure (5) and a gimbal mechanism (17) comprising two gimbals and mechanically connecting the two ends of the flexible area (13, 14).

Description

technical field [0001] The present invention relates to a method for manufacturing a light guide. It also relates to a method for producing a device comprising such a light guide. [0002] This method allows users to manufacture a light guide reliably, quickly and cost-effectively. Background technique [0003] A general light guide is usually a plate made of transparent material, which is arranged between the following two: [0004] multiple light sources; and [0005] An object used for lighting or backlighting (such as personal computer screen or mobile phone screen, billboard, light module, etc.). [0006] The plate is arranged to conduct and diffuse, preferably as uniformly as possible, light from the light source towards the illuminated or backlit object. [0007] Methods for manufacturing a light guide are known in the prior art. For example (French Patent No. 2960069B1), it could be: [0008] manufacturing a plate of transparent material by extrusion, said plat...

AI Technical Summary

Problems solved by technology

[0011] This method requires considerable steps, labor, and specialized materials, and thus may be time-consuming and / or expensive to implement

[0012] Furthermore, it may not always be possible to position each light source bar in the corresponding groove given that the width of the grooves is greater than the width of the light source bars in a precise and reliable manner

[0013] Finally, the general problem encountered may be to obtain the most uniform brightness
