Description

The utility model relates to lighting engineering, in particular to the design of lamps for utilitarian lighting GOST R 55844-2013 “Outdoor utilitarian lighting of roads and pedestrian zones. Norms ".

The proposed technical solution for utilitarian lighting covers such luminaire designs as lamps for street and road lighting, garden and park and landscape lighting, architectural and artistic lighting. According to the Lighting Business Consulting Group of Companies, in 2019 the market capacity of such lamps in the Russian Federation amounted to 1,638.2 thousand pieces. or 7962.5 million rubles.

Technical level

Known LED lamp - Patent for utility model 148024 U1. Russian Federation, IPC F21S 13/00. LED lamp: No. 2014117784/07: Appl. 04/29/2014: publ. 11/20/2014 / R.H. Tukshaitov, I.Kh. Kurmaev. The essence of the technical solution lies in the fact that the LED lamp contains a round multilens with a transparent outer surface with the required initial minimum angle of radiation. Achievement of the technical result consists in increasing the angle of radiation to the maximum permissible level by rotating the multilens at the appropriate angle relative to the geometric axis in the landing plane due to defocusing of the optical system of the LED lamp.

The disadvantage of this technical solution is the inability to change the type of the luminous intensity curve of the lamp.

Known LED lamp - Patent for utility model 189294 U1 Russian Federation, IPC F21S 8/04. Adjustable exposure light: No.2019106166: Appl. 05.03.2019: publ. 05/21/2019 / S.N. Kolomiytsev K.N. Tatarenko. The essence of the technical solution lies in the fact that the adjustable exposure lamp consists of a power supply module and an adapter providing electrical and mechanical connection to the track, connected to each other by a vertical hinge, an optical module hingedly connected to the power supply module by a horizontal hinge and consisting of a cylindrical body, a lens , installed in the window of the optical module and fixed with a hood, and an emitting element placed with the possibility of longitudinal movement inside the body of the optical module along at least one internal longitudinal guide, while the emitting element consists of an LED light source and a cylindrical radiator, and the LED source is fixed at the end the radiator from the side of the optical module window, while on the other side of the radiator a blind threaded hole is made in it, with which the screw interacts, which, according to the technical solution, is fixed with the possibility of rotation on the transverse a traverse mounted on the end of the optical module housing and equipped with a manual handwheel, and a film diffuser of surface scattering with an axisymmetric scattering indicatrix with a diameter equal to the diameter of the lens adjoins the flat side of the lens, while the film diffuser is installed with the scattering surface towards the lens, and in the hood built-in surface scattering film diffuser with non-Rayleev double-symmetric scattering indicatrix.

The disadvantage of this technical solution is the inability to change the type of the luminous intensity curve of the lamp and the complexity of manufacture.

Known LED lamp - Patent No. WO 2013187804 A1, IPC F21S 8/00, F21Y 101/02, F21V 14/00. LED lamp: No. PCT / RU 2013/000472: app. 07.07.2013: publ. 12/19/2013 / A.I. Kogdanin. The essence of the technical solution lies in the fact that the LED lamp contains a housing with a printed circuit board fixed in it, on which the LEDs are located, a primary optical system and a secondary optical system, characterized in that the LEDs form segments on which the primary optical system is directly installed, and above it there is a secondary optical system containing groups of lenses and installed with the possibility of radial movement relative to the axis of the luminaire.

This technical solution was chosen as a prototype. The disadvantage of this technical solution is the presence of a primary optical system, which complicates the manufacture of this design.

The purpose of the utility model is to improve the functional characteristics of the LED lamp while maintaining its consumer qualities.

The technical result of the proposed utility model is to improve the functional characteristics of the LED lamp in terms of the possibility of changing the luminous intensity curve without dismantling the lamp.

The technical result is achieved by the fact that an LED lamp containing a cylindrical body in which a power supply device, a round-shaped LED module and a round-shaped lens unit are installed, differs in that the lens unit contains three types of lenses for formation: wide circular (A), concentrated with with a radiation angle of 25 degrees (B), concentrated with a radiation angle of 12 degrees (C) of the luminous intensity curves, the lens unit is attached to the body with a nut with a sealed insert, so that when the nut is loosened, the lens unit can be rotated and the luminous intensity curve of the luminaire can be rotated (A, B , V).

Further, the essence of the utility model is illustrated by drawings.

FIG. 1 is a schematic view of the construction of a LED lamp. Here: 1 - LEDs, 2 - lens unit, 3 - nut with a sealed insert.

Experimental studies have been carried out to confirm the positive effect. The LED lamp is made. The values of the luminous intensity curve were measured, the measurement results are shown in FIG. 2.

FIG. 2 - curves of the luminous intensity of the LED lamp. Here: A - wide circular, B - concentrated with a radiation angle of 25 degrees, B - concentrated with a radiation angle of 12 degrees, luminous intensity curves.

Thus, an increase in the functional characteristics of an LED lamp has been experimentally confirmed in terms of the possibility of changing the luminous intensity curve without dismantling the lamp. By using a lens block for 3 luminous intensity curves, assembly efficiency is significantly increased and warehouse and manufacturing costs are reduced.

The performed patent research and analysis of other sources of information showed that the proposed technical solution is new, possible for industrial production with an experimentally confirmed positive effect.
