Description

The utility model relates to lighting engineering, in particular to light sources - lamps on light-emitting semiconductor diodes and is intended for use as a light source in lighting systems for various purposes.

Currently, LEDs are used as light sources, which have a number of advantages over fluorescent lamps and incandescent lamps.

As a result of the use of LEDs in lighting technology, there are difficulties associated not only with the correct distribution of light from the LEDs in the right direction, but also with the removal of heat generated during operation of the LED emitters.

For heat dissipation, various technical solutions are used that require the use of additional equipment of LED lamps. It can be a special device for cooling LED lamps (elements) by forced blowing with forced air. Or use special radiators to remove heat.

All these devices significantly complicate the design and, accordingly, lead to its cost increase.

Also, LED emitters are often enclosed in special translucent caps (flasks) filled with gas for heat removal from the light emitting elements.

This also leads to a rise in the cost of the structure due to the use of a significant number of additional component parts, as well as to a decrease in the operational properties of the structure due to the deterioration of heat dissipation from light-emitting elements.

For example, LED lamp designs are known, including a housing, current leads, and light emitting elements with LEDs (the well-known LED LTD lamp is a corn type lamp, as well as a lamp according to patent RU 2399833).

The absence of a cavity in the central part of the lamp significantly worsens heat dissipation, increases material consumption and complicates the design as a whole.

The closest in technical essence and the achieved result to the claimed utility model is the design of the LED lamp, known from patent RU 2470220 dated 12/20/2012. This lamp includes a housing with an end mounted perpendicular to its longitudinal axis, a board, current conductors and light-emitting elements in the form of plates with built-in LEDs. The plates are installed at the same distance from each other and are equidistant from the axis of the lamp.

Compared with the previous analogue, the material consumption of the structure is reduced and the heat sink is improved, however, the design is complicated by the presence of individual flasks for each light-emitting element, and in addition, gas or liquid is used for heat removal, which are placed in the above flasks.

The claimed utility model is aimed at improving performance while simplifying the design.

The proposed result is due to the fact that the LED lamp is bulbless. In this case, the lamp includes a hollow body with a board located inside it, light-emitting elements and current guide means. The light-emitting elements are made in the form of oblong-shaped plates with built-in LEDs. In addition, the light emitting elements have an open surface and are installed at intervals between them, parallel to the longitudinal axis of the housing, along the perimeter of one of its bases.

Light-emitting elements are distributed uniformly along the perimeter of one of the bases of the housing.

The lamp housing can be made in the form of a polygonal prism, and the current lead means can be made in the form of a cap or in the form of wires going from the housing.

The implementation of an LED lamp - bulbless and with an open surface of light-emitting elements will improve its operational characteristics, namely, since the surface of the plates with diodes built into them is in direct contact with the surrounding air from all sides, the heat sink is carried out by natural air convection. It does not require the use of additional heat agent (gas or liquid). In addition, when performing light-emitting elements with an open surface, there are no easily breaking glass elements in the form of individual flasks, as well as a common protective flask, which increases the safety of the structure when it is used, simplifies the structure as a whole and reduces its cost.

The essence of the claimed utility model is illustrated by graphic materials, where:

In FIG. 1 shows a General view of a bulbless LED lamp with a current lead in the form of a cap;

in FIG. 2 is a front view of FIG. 1;

in FIG. 3 is a top view of FIG. 1;

in FIG. 4 is a general view of a bulbless LED lamp with a current lead in the form of wires coming from the housing;

in FIG. 5 is a front view of FIG. 4;

in FIG. 6 is a plan view of FIG. 4.

The proposed design includes a hollow housing 1. Inside the housing 1, for example, on one of the bases 2, perpendicular to the longitudinal axis 3 of the housing, a board is mounted (not shown in the drawing), on which light-emitting elements are placed in the form of oblong-shaped plates 4 with built-in LEDs 5. The plates 4 are distributed at intervals between each other along the perimeter of the base 2 of the housing 1. The plates 4 of the light-emitting elements are parallel to the longitudinal axis 3 of the housing (perpendicular to the base 2 of the housing). This arrangement provides a uniform distribution of light flux in the surrounding space. Current leads can be made either in the form of a cap 6 (screw or pin), or in the form of wires 7 coming from the housing. The shape of the case may differ from cylindrical. For example, it can be in the form of a polygonal prism (in cross section a square or another polygon).

The lamp is bulbless. The surface of the light emitting elements is made open. This innovation solves the problem of heat removal due to natural air convection, without requiring any additional equipment, which greatly simplifies the operation of the structure and reduces its cost.

Thus, the proposed design compares favorably with previously known simplicity, low cost and higher performance properties.
