Rotary and not rotary halopgen ceiling luminaires.

For the general and local illumination of public premises of various appointments (trading and auditoria halls, halls of hotels, theatres, offices, etc.), can be installed in false ceilings, and also used for mirrors, show-windows, furniture highlight, for an interior creation.

Modern design, wide color assortment of a covering for the luminaries case. The case of the lamp is made of metal. Lamp is connected to power supply through terminal-block clips. Double economy of electric power comparing to regular incandescent lamps, that produce the same luminous flux. Lamp socket, type G ТУ РБ 07615377.070-98 , allows to replace a lamp without dismantle of the whole luminaries.

Design of lamps:

Two types of ceiling luminaires are manufactured by Minsk factory "Calibre": ИП0 47-50-032 and ИП0 47-50-041. Appearance, overall dimensions and installation instruction are given in fig. 1 and fig. 2 accordingly.

Halogen lamps КГАФ 12-50 and КГИФ 12-50 (or foreign analogue) are used as light sources. Fig. 3 shows dependencies of light stain diameter and illumination level on distance to a light source; fig. 4 - shows a typical curve of light spread for halogen lamps КГАФ 12-50 (КГИФ 12-50). Lamp is connected to AC or DC 12V power supply (power min 50 W) through terminal-block clipses (6).

Minsk factory "Calibre" offers power supply unit БПГ 220/12-2х100 W for power supply of several (up to 4) ceiling halogen luminaires, or the transformer ТЭ 220/50 for power supply of one luminaire. The specified power units are developed and manufactured by Minsk factory "Calibre".

Advantages:

• High density of luminous flux in a shined zone;
• Double economy of electric power comparing to regular incandescent lamps, that produce the same luminous flux;
• Service life of halogen lamps in 2-2,5 times more than service life of regular incandescent lamps.

The design of halogen ceiling luminaires grants simple and convenient mounting to false ceilings by means of springs without application of any tool. Ceiling luminaire ИПО 47-ЗО-041 gives an opportunity to change light direction without application of any tool.

The luminaries are certified and meet requirements of ГОСТ 17677-82, ГОСТ 8607-82.
