The invention relates to lighting equipment and can be used for the purposes of General and local lighting.

Known mine lamp for individual use, consisting of a rigid profile located on its outer side led out of the housing for mounting the hard profile and to set the device power LEDs, as well as from external containment required under the terms of the placement of the lamp in the mine (EN 2187039, IPC F21L 4/00, publ. 10.04.2002).

A disadvantage of the known lamp is a limited scope, due to the uncertain shape of the light intensity curve, which excludes its use in accordance with the sanitary and building nor design, production, service, administrative, residential and other premises where it is required to provide a given level of light in different directions, as determined by the light intensity curve of the light unit is one of the most important GOST characteristics of the light unit.

Luminaire with symmetrical light intensity curve contains (1) a rigid profile, made in the form of the sphere 1, which is divided into zone 2 boundaries in the form of circles 3, separated from each other by angles αiαi-1lying in the same plane between the axis OO1hard profile 1 and the rays directed along the radius of the sphere and intersecting the boundaries of zone 2, which equal the size of the available LEDs 4 along the middle of the circle 5 of each zone 2 with angular distance Δβ ibetween the LEDs 4.

The device to power LEDs is used to supply required for each power led as simultaneously on all the LEDs, and in the appointed order and can be located in the same housing with a rigid profile for placement of LEDs and separate, for example, on the base of the light unit. Source for device power LEDs can be both AC and battery cells included in a lighting device, in accordance with the scheme of the device used to power the LEDs.

The LEDs 4 can be located on the inner or outer side of the surface of a rigid profile, made in the form of the sphere 1, which is divided into zone 2, the boundaries of which are of a circle 3 lying in planes perpendicular to the axis OO1hard profile 1, and spaced from each other at angles αj-1αj(1)lying in the same plane between the axis OO1hard profile 1 and the rays directed along the radius of the sphere and intersecting the circles bounding the i-th zone, inside which the internal or external parties are LEDs 4.

For a given sphere radius corner size Δα=αjαj-1zone is selected so as to ensure that the width of the area, it is possible to accommodate a single row of LEDs. The centers of the bases of the LEDs 4 are average in relation to the boundaries of the zone 2 of a circle 5.

The number of zones 2 is calculated from the ratio

where αbefore- limit the angle of light intensity curve over which the power of the light takes the value of zero;

Optical axis of each led 4 coincides with the direction of the radius of the sphere, and the axial force of the light from it is directed toward the center of the sphere. The resulting curve of the light intensity of all the LEDs 4 in the case of performing the correlation corresponds to a given light intensity curve.

Figure 2 shows a rigid profile in VI the e part of the sphere 1 with necroposting light intensity curve and asymmetric arrangement of the LEDs 4 to zone 2. Border zones 2 bubbles 3 are separated from each other at angles αiαi-1lying in the same plane between the axis O1O2hard profile 1 and the rays directed along the radius of the sphere and intersecting the boundaries of zone 2, which posted the LEDs 4 along the middle of the circle 5 of each of the zones 2, which divided the traces 6 from the intersection of the profile planes passing through the axis O1O2on q - part arcs 7 with angular distance βi1βi2,... βiq(where j=1,2,...q, where q is the limit value of the parts that is broken i-th zones). Angular distance Δβijbetween the LEDs 4 are different for each arc (Δβi1, Δβi2,... Δβiq). In this case, the part of the sphere 1 has several zones with 2 borders 3 and 4 LEDs are located along the middle circle 5 zones each 2 each arc 7 with different angular step is inversely proportional to the number of LEDs 4 on a dedicated area 2 in accordance with a given necroposting light intensity curve.

The number of zones 2 is calculated from the relation (1).

With an asymmetric distribution of LEDs angular distance between the centers of the bases of the LEDs 4 along the middle of the circle 5 of the i-th zone for the j-th arc is defined as

where βijangle of the j-th arc for the i-th zone, lying in pleskot is, perpendicular to the axis O1O2hard profile 1;

nij- number of LEDs 4 for the i-th zone of the j-th arc, which is defined as

where Iαβ- is the power of light, selected from a given light intensity curve for the angle lying between the axis O1O2hard profile 1 and the beam crossing average circumference 5 of this zone, and for angle lying in a plane perpendicular to the axis O1O2hard profile 1 and formed by the beam, which is the bisector of the angle at which the arc lies with j=1, and the beam, which is the bisector of angle for the j-th arc (j=1, 2,... q);

ωαβ- corporal, lying between the angles of this zone and the angle of this arc;

k - coefficient of proportionality.

The light fixture works as follows. When power to the device power LEDs last 4 supplies power to each of the 4 LEDs located on the hard profile as part of sector 1 in the desired sequence. The radiation from the LEDs 4 generates a force of light according to the required light intensity curve.

The arrangement of LEDs 4 on the outer or on the inner surface of the hard profile as part of sector 1 does not matter, because in fact or in other cases is desired spatial power distribution of the light from the led Halloween gift is s 4.

Compared with the known solution proposed allows to ensure the creation of a lighting device with a specified light intensity curve, which ultimately improves the quality of lighting according to the required specifications.

The light fixture including the LEDs and the hard profile of the holder of LEDs, wherein the rigid profile, made as part of the sphere that contains zones, each of which is limited to circles, and the average circumference of each zone on the internal or the external side surface located LEDs, the number of zones is equal to
