Embodiment Construction

[0018] The present invention generally relates to low cost sealed light sources. It uses standard equipment parts, especially in relation to lampholders, which are traditional low-cost lampholders, sometimes called flat lampholders.

[0019] A light source according to the invention comprising:

[0020] - a body consisting of a half-shell, called a "roof", having means for fixing it to any type of support such as a ceiling,

[0021] - a transparent cover or "diffuser" that can be moved aside to allow access to the interior of the light source

[0022] - mounting plate, made of a piece of formed or really folded sheet metal, which carries the internal functional parts of the light source, among them the ballast and the lampholder for the fluorescent tube.

[0023] figure 1 Is a perspective view of a mounting plate (1) for an elongated light source, comprising a socket support tongue (3) according to the invention in its initial position. This location indicates that the con...

Abstract

The present invention relates to a luminaire of elongated shape comprising an elongated mounting-plate (1) carrying internal functional components of the luminaire. The mounting-plate comprises at least one lampholder-supporting tongue (3) that is cut out in the mounting-plate by punching. The tongue remains integrally connected to the plate and is capable of undergoing rotation through 90 DEG from an initial position to an in-use position about a bending axis (7) along which the tongue is connected to the plate. The mounting-plate also comprises an abutment (6), produced by stamping, which enables the rotation of the lampholder-supporting tongue to be limited to approximately 90 DEG .

Description

technical field [0001] The invention relates to an elongated light source with an elongated mounting plate for supporting internal functional components of the light source. Background technique [0002] Conventional light sources include a mounting plate provided with openings to allow a fitter to insert a pair of sockets for fluorescent tubes, the sockets of which pass through the plate. In this type of conventional light source, the pair of lamp holders are fixed through the board by inserting the pair of lamp holders on the side opposite to the wiring side to which the lamp holders are fixed. The light source is therefore powered using unmounted lamp holders; in the case of more than one fluorescent tube, fitters can make mistakes in securing the lamp holders to the mounting plate because they do not have access to the wiring for the lamp holders. Alternatively, the light source can be powered with a lampholder already fitted to the mounting plate, but the package would...
