Luminescent luminaires with plastic diffusor.

Are intended for:

For the general and local illumination of public premises of various appointments (trading and auditoria halls, halls of hotels, palaces of culture, theatres, libraries, clubs, administrative and educational premises, offices, etc.).

Ceiling luminaires ËÏÎ have 4 apertures 7,5 mm in diameter in case of the luminaire for fastening to ceilings by means of dowels and screws.

Built in luminaires ËÂÎ are intended for installation in niches of false ceilings right on bearing channels of ceilings.

The lumunaires can use both electromagnetic (ÏÐÀ) or electronic (ÝÏÐÀ) start up devices.

Dependence of luminous intensity on a direction in the bottom hemisphere corresponds curve Ä (cosine), according to ÃÎÑÒ 17677-82.

ADVANTAGES:

• high, uniform lumenous flux level in a shined zone;
• encreased efficiency, more comfortable illumination and electricity economy;
• lowered level of acoustic noise;
• Luminaires, using ÝÏÐÀ possess additional benefits:
• Instant turn on and silent operation;
• Uniform light without blinking and absence of stroboscopic effect at the expense of high-frequency functioning of light sources. That is why they are recommended for application in infant schools and schools, where it is especially important to exclude influences of lumenous flux fluctuations on sight and nervous system of children and teenagers;
• 20 % increased service life of lamps at the expense of optimum operation control mode;
• 20 % electric power economy comparing to lamps using traditional start up devices;
• No electromagnetic interference during operation.
