Description

The utility model relates to lamps, mainly for lighting squares, parks and streets with one-story buildings.

Known lamp from the RF patent for invention No. 2106571, IPC E21R 3/00, publ. 03/10/1998

This luminaire contains a support of a complex shape that can be changed in operation, and one lantern fixed in the upper part of the support.

Disadvantages: the complexity of the design due to the very complex design of the support and insufficiently efficient lighting due to the use of one lamp.

Known lamp from the Internet site https://market.yandex.ru/product--arte-lamp-sadovo-parkovyi-svetilnik-malaga-a1086pa, prototype (Appendix 1).

This luminaire contains a support and two lanterns, identical in shape and size, with incandescent lamps, fixed on it oppositely in the upper part on cantilever pipelines. Lanterns contain a body, a light source and a diffuser, in the form of a ball.

Disadvantages of this lamp:

the complexity of the design of the lamp, which is due to the fact that it uses a support of complex shape and in the upper part two cantilever pipelines are used for opposite hanging of lamps,

low-tech manufacturing of parts for it: the use of casting for the manufacture of supports,

possible swinging of the support due to the high windage of the lanterns and the large distance between them,

fast pollution of lanterns due to their spherical shape.

The task of creating a utility model: simplifying the design of the lamp.

Technical result achieved: simplification of the design of the lamp.

The solution to this problem was achieved in a luminaire containing a support and two identical lamps fixed on it oppositely in the upper part, containing a body, a light source and a diffuser, characterized in that the support is made of a rectangular shape of constant cross section and hollow in cross section, the lamps are made annular with housings having the shape of a rectangle in cross section, the diffuser is fixed along the diagonal of the housing rectangle, the lamps are fixed oppositely on the smaller faces of the support and at different heights, the light sources are made in the form of LEDs (LED strip or LED strips) on reflectors installed in the cavity of the lamps.

Reflectors can be installed in the cavity of the lanterns at an angle to the horizontal surface

α=30…60°.

The large face of the cross section of the support can be made from the relation

e=(1.8…2.2)d,

where e is the width of the larger face of the cross section of the support,

d is the width of the smaller face of the cross section of the support.

The thickness of the cross section of the support is made constant and from the ratio

δ=(0.08…0.12)d,

where δ is the thickness of the cross section of the support,

d is the width of the smaller face of the cross section of the support.

The support can be made of metal.

Lamp housings can be made of plastic.

Lantern housings can be made of metal.

Lantern housings can be painted on the outside with a corrosion resistant coating.

The diffuser can be rounded with radius R along the entire perimeter towards the lantern cavity.

The features of the first claim of the utility model are necessary and sufficient to achieve the claimed technical result.

The features of claim 2 of the formula of the utility model make it possible to expand the zone of maximum illumination under the lanterns.

Signs of paragraphs. 3…5 formulas of the utility model make it possible to ensure the strength of the luminaire and better resist bending loads from the weight of lanterns 2 and 3 when they are swayed by the wind.

The features of item 9 ensure the minimization of pollution of the diffuser during long-term operation and its thawing in the spring-autumn period.

The design of the lamp is shown in Fig. 1-10.

In FIG. 1 and 2 shows a lamp, it contains a support 1 and two lamps 2 and 3 identical in shape and design, and the base of the support 4 in the lower part.

Support 1 is made in the form of a rectangular and constant in cross-section rod with edges (Fig. 3):

d - the width of the smaller face of the cross section of the support,

e is the width of the larger face.

The large face of the cross section of the support 1 can be made from the ratio (Fig. 3)

e=(1.8…2.2)d,

where e is the width of the larger face of the cross section of the support,

d is the width of the smaller face of the cross section of the support.

This design allows for the manufacture of support 1 to use rolled products produced commercially. This will simplify the design of support 1 and make it more manufacturable and cheaper to manufacture.

In FIG. 4 shows the top view of lamps 2 and 3.

Both lanterns 2 and 3 are identical in shape and design. They are annular in shape and have an outer diameter of the lantern D _n and a lantern width in terms of h.

At the same time, it is recommended to carry out the width of lanterns 2 and 3 of the luminaire in the plan within

h=(0.1…0.2)D _n ,

where h is the width of the lantern,

D _n - outer diameter of the lantern.

This also contributes to the expansion of the zone of maximum illumination under the lanterns.

In the lower part of the support 1 is installed, for example by welding, the base of the support 4.

In FIG. 5 shows the body 5 of the lantern 2 in section. It contains a horizontal part of the body 6 and a vertical part of the body 7. The body 5 can be made of plastic or metal with an anti-corrosion coating 8 on the outer surface, for example, paint or enamel.

The compartment cover 9 is located on the vertical part of the body 7 and is intended for access to the power supply unit of the illuminator.

A diffuser 10 is installed on the lower part of the housing 5 (Fig. 5), which together forms an internal cavity 11. A reflector 12 is installed in the internal cavity 11, on the surface of which LEDs 13 are fixed at an angle α to the horizontal plane (in the form of an LED strip or LED strips ). The use of LEDs 13 reduces the consumption of electricity by lamps compared to incandescent lamps by an order of magnitude.

Screws 14 (Fig. 6) fasten the compartment cover 9 to lamps 2 and 3.

Optimum reflector installation angle 12 to the horizontal plane

α=(30…60)°.

This can be seen in the drawings below (Fig. 7...9) of the illumination under the lanterns, depending on the angle of the reflector 12.

From FIG. 8 it follows that the optimal installation angle of the reflector 12 is

α=30°…60°.

In this case, the zone of good illumination 15 will be solid, and the zone of mediocre illumination 16 will be wide.

The rounding of the diffuser 10 around the entire perimeter with a radius R ensures minimization of the pollution of the diffuser during long-term operation and its thawing in the spring-autumn period due to a decrease in the internal volume of 11 lamps and their heating from LEDs 13.

Assembly and operation of the lamp.

Supports 1 and lanterns 2 and 3 are made separately.

Since support 1 is made of the simplest form from a commercially available profile, it will turn out to be simple in design and technology. The internal cavity of the support 1 allows you to lay cables there for supplying electricity, turning on and off LEDs 13 (in the form of LED strip or LED strips)

In the manufacture of lamps 2 (or 3), a housing 5, a diffuser 10 and a reflector 12 with LEDs 13 are separately manufactured.

The use of LEDs 13 instead of incandescent lamps will reduce the energy consumption of the lamp by about 10 times.

After assembling the luminaire, it is installed on the base of support 4 on a specially equipped pedestal (the pedestal is not shown in Fig. 1 ... 10), previously dug into the ground and screwed with fasteners.

The use of the proposed lamp allowed:

simplify its design,

improve the manufacturing technology of lamp parts,

expand the range of the illuminated surface with minimal energy consumption through the use of LEDs and their installation at an angle to the horizon,

to prevent contamination of the lens 10 during long-term operation and freezing of its surface at low sub-zero temperatures in the spring-autumn period due to its location in the lower part of the housing 5 and rounding with a radius R into the internal cavity 11 of lamps 2 and 3.
