The essence of the invention: the housing 1 and the lid 6 of the luminaire are provided with protrusions 2 directed towards each other, cylindrical bushings and nuts 8, and in these protrusions 2 the control gears 4 are placed, the ends of tubular lamps 9 and sealing gaskets are placed in cylindrical bushings 8, while the nuts 8 are made in the form of a glass with a central hole in the bottom and diametrically located radial protrusions on the opposite end. 6 Il.

Description

The invention relates to lighting engineering, in particular to luminaires with tubular light sources, and can be used in lighting devices operating in an environment that adversely affects the performance of contact systems.

A lamp is known, comprising a housing consisting of two parts with caps interconnected by a massive rigid element. Parts of the housing are placed at the ends of the tubular lamps.

The disadvantages of this lamp are high consumption of materials, structural complexity and low manufacturability.

Also known is a luminaire comprising a housing made in the form of two rectangular boxes with lids, placed at the ends of the tubular lamps. In parts of the case interconnected

rigid element placed control gears and lamp sockets.

The disadvantages of this luminaire are:

-the complexity of the design;

- low reliability and service life of the lamp due to the lack of fixation of the gasket (sealing line) between themselves in the direction of the longitudinal axis of the lamp and, as a consequence, the formation of a gap through which aggressive substances penetrate into the housing cavity, causing increased corrosion of metal parts, especially electrical contacts;

- high material consumption of the lamp due to the placement of massive units of the lamp (body parts with control gears located in them) at the ends of the lamps far from the center of gravity, which entails the need to perform a rigid element

Noah strength of the workpiece large length and thickness;

- insufficient unification due to the holes for inserting lamps in parts of the body of a certain diameter, which does not allow the use of lamps of a different diameter without compromising the protection of the contents of the body from environmental influences.

The aim of the invention is to simplify the design, reduce the material consumption, increase the reliability, service life and unification of the lamp.

The goal is achieved by the fact that in the luminaire comprising a housing consisting of two parts with lids connected by a rigid element, control gears, lamp sockets, tubular lamps and sealing gaskets, parts of the housing and the lid are provided with projections directed opposite to each other, cylindrical bushings and nuts, with control gears placed in the projections, tubular lamp ends and sealing gaskets placed in cylindrical bushings, which are fastened with nuts; s in the form of a cup with a central hole in the bottom of a diametrically placed radial projections at the opposite end.

FIG. 1 shows the proposed fixture, general view; in fig. 2 - the same, top view; in fig. 3 - lamp sealing unit (cross section); in fig. 4 shows section A-A in FIG. 3; in fig. 5 and 6 - nut, general view.

The lamp includes a housing 1, a protrusion 2, a rigid element 3, control gears 4, bolts 5, covers 6, sealing gaskets 7, nuts 8, tubular lamps 9, lamp sockets 10, bushings 11, tides 12, hooks 13, wires 14, for - main projections 15 and hollows 16.

Example. The housing 1 and the lid 6 are made of electrically insulating material, for example, glass-filled polyester plastic - premix. Along the inner perimeter of the lid 6 there is a trapezoidal protrusion, and along the inner perimeter of the casing 1 a groove repeating along the profile.

Trapezoidal junction reliably provides sealing properties for

both opposite sides of the trapezoid without the use of elastic pads while simultaneously fixing the position of the lid relative to the body due to jamming over the entire mating surface. Parts of the case and cover are made T-shaped.

Control gears are located in the protrusions that are placed between two tubular lamps and directed towards each other.

The dimensions of the gaskets are larger, for example, by 2 mm of the size of the bushing seat, and the lamps are worn with tension.

The sleeves are made in the form of hollow semi-cylinders with a variable cross-section of the walls and are equipped with tides that are diametrically placed on the outer surface of the sleeve opposite the connector line of the housing and the cover at the places of the greatest cross-section of the walls.

The design of the quick-release nut is a cup with a central hole in the bottom for the passage of the tubular lamp and diametrically arranged radial, inwardly protrusions on the opposite end.
