Luminaire, suspension means and methods for suspending, respectively demounting a luminaire

Abstract

Luminaire (1) comprising suspension means (3) and a housing (5) with a top wall (7). Said suspension means (3) comprising a hook (9a, b) formed of an elastic wire (11) with a loop portion (15) connected to two remote, oppositely arranged end portions (13a, b) each forming a spindle (17a, b), and two elongated channel elements (19a, b) arranged along a rotation axis (21) and mounted on the top wall (7), with each spindle (17a, b) being snugly fitted in a respective channel element (19a, b). By a mutual misalignment between the spindles (17a, b) and the channel element (19a, b) with respect to the rotation axis (21), the hook (9a, b) is in a low tension state when in a first rotational position (27), and in a high tension state when in further rotational positions (29) and urging the hook (9a, b) to assume the first rotational position (27).

Description

technical field [0001] The invention relates to a lamp. The invention further relates to a suspension device suitable for use in a luminaire. The invention still further relates to a method for hanging and demounting said luminaire. Background technique [0002] Luminaires that provide convenient ambient lighting for commercial offices and industrial spaces are often used in false or suspended ceilings and are often referred to as troffer lighting fixtures. An example of such a troffer light fixture is disclosed in US20150267873A1. In many installations, these fixtures include one or more straight or U-shaped fluorescent lamps that span the length of the fixture. These troffer fixtures are often used as modular fixtures to build light tiles and / or lights for false ceilings. Typically, these modular luminaires are then closely surrounded by adjacent modular luminaires and / or adjacent false ceiling tiles. [0003] As these luminaires age, there is an increasing need or de...

AI Technical Summary

Problems solved by technology

However, repairing electronic components and lamps for recessed luminaires is often expensive and time-consuming, because in addition access to recessed parts of the luminaire is required in many cases

Said access to known luminaires involves the disadvantage of being relatively difficult to service, since said access is usually via the suspension structure of the luminaire comprising a removable or pivotable door frame

Luminaires comprising such known suspension structures cause some of the electronic components of the luminaire to be located on vertically suspended door frames and / or components of the luminaire stay above during maintenance in recesses in the false ceiling, which makes maintenance cumbersome, and an additional disadvantage involving an increased risk of dropping parts or tools
