Description

Technical field

The utility model relates to the field of durable lighting devices with solid-state semiconductor light sources and is intended to produce directional light. The product can mainly be used for street lighting, as well as industrial, domestic or architectural design.

State of the art

The known solution of the lamp, selected as a prototype of this utility model - patent RU 83314 U1, F21S 4/00, F21V 14/00, 12/30/2008. This product is used mainly for street lighting and is mounted on the console of the lighting support. The housing is an integrated design of three functional elements: the housing itself, the radiator, and the bracket. In order to obtain half-wide or wide KCC diagrams, light modules are placed on the inclined surfaces of the walls of the W-shaped profile. The extreme walls of the profile are used as reflective surfaces. By adjusting the tilt, for which replaceable wedges are used, the KCC diagram is adjusted. The casing layout is made by sequentially placing its functional elements in a line: a bracket, a power supply compartment, a light module compartment in such a way that a niche for a current source is placed between the bracket and the niche for the light modules. However, with this arrangement, there is an excessive increase in the mass of the housing, and therefore the price of the lamp, which can be attributed to the disadvantages of the device. In addition, the heat dissipation capabilities of the radiator are underestimated, since the heat sources - light modules are concentrated in the central part of the housing, and the area of the heat dissipating elements and their mass are distributed evenly over the lamp, which also relates to the disadvantages of the prototype. The layout in line also increases the dimensions of the lamp, which negatively affects the transport and logistics costs of its implementation.

The disadvantages of the prototype is the concentration of heat sources (light modules) in one zone, which negatively affects the operating modes of the light sources.

The technical objectives of the claimed utility model are:

- improving the heat dissipation of the lamp housing, which will lead to a decrease in its mass, and hence the price of the lamp;

- reduction of the dimensions of the lamp.

Utility Model Essence

The device consists of a body-radiator-bracket made of heat-conducting material, light modules, a power source and a protective screen.

The technical result is achieved by the layout of the housing-radiator-bracket, in which the compartment under the light modules is two V-shaped niches, between which there is a compartment for the power source and the bracket. This allows you to distribute heat sources, to concentrate more than the mass of heat-conducting material directly in the heating zone, i.e. effectively use the mass of material that goes to the realization of simultaneously supporting functions in the form of structural parts of the power supply compartment and the bracket and heat dissipation functions when these parts perform the function of a radiator. The location of the structural elements of the supports (cantilever) inside the bracket in the area of heat generation also contributes to its more efficient dissipation. For the same purposes, thickening of the material in the zone of location of the light modules was performed, in contrast to the prototype, where the cross section is the same throughout the profile. In addition, the heat-dissipating fins are outside the housing, which provides a more efficient circulation of air flows and, therefore, their more efficient cooling. These measures make it possible to carry out a housing of a luminaire of a lower mass, and therefore, make it cheaper. In addition, this arrangement reduces the dimensions of the luminaire, and hence the transport and logistics costs of its implementation.

The introduction of a sealant into the design of the luminaire between the light-transmitting shock-resistant screen and the casing allows preventing moisture and dust from entering the luminaire, i.e. to increase its price and moisture, as a result, to increase reliability.

Thus, the essence of the measures introduced is reduced to the following solution of the lamp:

A lamp comprising a shockproof light-transmitting screen, a housing-radiator-bracket made of heat-conducting material, combining the functions of the housing, radiator, bracket; light modules and a power source, respectively placed in the compartments of the light modules, with the modules placed on the inclined walls of the profile niches, the extreme surfaces of the walls being mirrored and the reverse side of the profile made with outgoing heat-dissipating fins; and a compartment for a power source of the housing, characterized in that the compartment for the light modules is two V-shaped niches between which there is a compartment for the power source and an arm; the location zones of the light modules of the V-shaped niches have a thickened section; the ribs go beyond the housing; between the light-transmitting shock-resistant screen and the housing is a sealant.

In addition, claimed as a utility model, the lamp has the following features:

- housing-radiator-bracket is made integral.

- the function of the mirror surfaces of the extreme walls is performed by mirror plates mounted on the extreme surfaces of the walls of the V-shaped profiles. This eliminates the time-consuming processing of the inclined surface of the housing, the use of mirror plates, the reflective characteristics of which exceed the characteristics of the coating of the inclined surface, and in addition, carry out their independent processing.

- the modules are rigidly fixed to the casing-radiator-bracket with screws or self-tapping screws, or heat-conducting adhesive, or heat-conducting adhesive tape.

- each of the light modules contains at least one solid-state semiconductor light source.

- each of the light modules contains at least one solid-state semiconductor light source made using chip-on-board technology (chip on the board).

- each of the light modules uses solid-state semiconductor light sources of monochrome light, while the inner surface of the light-transmitting screen is coated with a phosphor, as a result of which the monochrome light is converted to white.

- light-transmitting shockproof screen made of diffusing material.

- the screen is made in conjunction with modular optics containing lenses, which allows you to adjust the KSS diagram for the desired configuration of the distribution of light flux.

- for operation of the luminaire in the suspended version, on the back side of the power supply compartment, lugs for fastening eyebolts are provided.

Utility Model Implementation

An outdoor LED lamp can be implemented as follows: A power supply is mounted in the housing-radiator-bracket 1, in the compartment 3 specially designed for this purpose. In the V-shaped niches of the light modules, light modules are installed on the inner inclined surfaces 7, fixed, for example, with screws. The power cables of the modules are laid along channels 6. Mirror plates are also installed in the extreme inclined surfaces of the 8 V-shaped niches, which are also fixed, for example, with screws. The specified angle of inclination of the walls of the niches of the light modules forms the necessary KSS according to the requirements of GOST 17677-82. The luminaire is sealed with a protective shockproof light-transmitting screen 2, while the connection is made through a sealing cord laid along the grooves 13, 16 or sealant with screws. The luminaire is mounted on the console through the hole 14 with two bolts fixed to the fasteners 15, or in a suspended version onto the eyebolts, for which the bosses are provided 10. The bracket 4 and the power supply compartment 3 are separated by a partition in which the hole 11 for the pressure seal is provided lamp power cable. For decorative purposes, the power supply compartment is hidden by applying corrugation 12 to the screen 2 in the area of the power source.

The lamp operates as follows. When the luminaire is connected to the mains, the power source supplies voltage to the light modules, solid-state light sources begin to emit light, and heat is generated, most of which is dissipated mainly by the luminaire body using heat-dissipating ribs 9, and part by external console structures through the mounting element on case with previously applied heat-conducting material. The KCC diagram is formed by light sources of light modules, reflecting inclined surfaces 8, a translucent screen 2 or a translucent screen with combined modular optics.
