1 catalogue 2010 INFRA - RED ILLUMINATION

2 The Tirex company, producer of the ELENEK illuminators, was founded in 1992 by specialists of the Physical and Technical Institute of Saint-Petersburg From the start the main activity of our company was the development and production of infrared illuminators. Since 1998 we produce the ELENEK infrared illuminators series. They found their way in a great variety of applications. The invisible illumination of public and private buildings The illumination of borders The illumination of railroad tracks As illumination on police surveillance vehicles The infrared light has a wavelength that can not be seen by the human eye. The Elenek illuminators have a wavelength of 870 nm (nanometres). Visible light has a wavelength of 350 to 750 nm. This infrared light is only visible by black/white cameras and by colour cctv cameras with IR cut filter. In general, all the characteristics of visible light are valid for infrared light. This includes the common effects as shadows and overexposure. This is also the reason why it is almost impossible to specify exact distances for infrared illuminators. How far does a bulb of 60 watts shine? The individual Leds are highly efficient and powerful. The power of the illuminators varies between 8 and 40 watts, depending of the type. This, in combination with the high quality of the illuminators, says a lot more than estimated distances.

3 properties ir illuminators Many security systems can profit from infrared illuminators. The main reason for the use of infrared illuminators is its hidden illumination, that is not irritating and guarantees comfort during night time. In combination with the highly sensitive black and white CCD and CMOS sensors of modern security cameras, you will have a higher yield than when using normal illumination. In the case of LED-based illuminators shock-resistance, reliability, and low power consumption are also big advantages. Generally speaking, these illuminators increase the efficiency and quality of security systems, and decrease its maintenance and exploitation costs. The main advantages of the Elenek illuminators are: its enormous efficiency, its outstanding reliability, and so a very good return on investment. This catalogue provides general information on Elenek illuminators. For more details and numerous special products, please visit our website: 5 years Reliability The illuminators are supplied with a 5 year warranty. To increase reliability and to eliminate hidden defects, we introduced a series of tests, checking diodes structures and electronic components. Thermo electrical cycling of diodes. During this test, the thermal resistance of the diodes is artificially increased up to 40%, and the diodes are working with current, that exceeds nominal values up to 2,5 times. Thermal cycling of diodes and assembled illuminators in temperatures from 60 up to +50 degrees C. Wide power supply range t All illuminators of the ELENEK series can be supplied with voltages ranging from 10,5 to 14. It compensates voltage decrease on connecting wires, and lets the illuminator work from a UPS with 13,5 14V voltage. Overheating protection Big surface radiators are mounted along with electronic overheating protection. If the illuminator will be let working during daytime under shining sun, the protection system will turn of the illuminators power supply, until the temperature will reach normal values again. Built-in photo-cell switch The photo-cell automatically switches the illuminators on during night time, and switches it off, during day time. The photo-cell switch is already adjusted to prevent a blinking effect. Voltage spikes protection. All Illuminators from the ELENEK series have a voltage peak protection system, effective to peaks of up to 50V. Mixed polarity protection All illuminators are protected from incorrect cable connection.

4 TECHNICAL DETAILS The Elenek IR illuminators are built using first quality infra-red spectrum Light Emitting Diodes (LED). These diodes consist of AlGaAs-heterostructures with a thick transparent substrate and have an inverted mesa configuration with both p and n contacts located on the rear surface. They are characterized by an increased-quantum value, extra-high efficiency and extra-low thermal resistance. The diodes are of the flip-chip emitting element type, mounted on a silicium carrier. Contrary to the usual vertical diode type, they do not have contacts on the upper (emitting) part. Due to this fact, the diodes show a highly uniform emission, and an even, balanced beam on the lighted object. There are three types of diodes, used in the Elenek illuminators: a line up of diodes with spherical lenses single diodes with double-lens technology diodes with a parabolic lens In the medium and short range type illuminator line ups are used, assembled to units (fig.1). Each unit consists of 4 emitting elements (1), mounted on one, highly heat-conducting Silicium carrier (2), covered by a protective film of Silicium Oxide. Each diode has an individual spherical lens (3), with an emission in the requested illumination angle. A variety of lenses make the production of different angles possible. Units are mounted on an aluminum base (4), intended to conduct heat to the illuminators radiator. In the long range series illuminators, along with these 4-diode type assembly units, single diodes with double lens technology are used (fig2). An emission element (1) is mounted on a silicium carrier (2). The spherical lenses (3 and 3*) are collecting both principal and lateral illumination and forming the necessary angle. These single diodes are provided with an individual heater (4) and can be operated with high currents, resulting in great emission value levels. In the white-spectrum and the special-type illuminators (up to 300m), single diodes with double, combined type lenses are used (fig.3). the first lens (3), covering the emitting element (1), is a spherical type lens. The second lens has a parabolic shape with a 41mm diameter and a height of 50 mm. This combination makes it possible to emit all the light in the requested illumination angle. This extra high efficiency of light collecting is based on a complete internal reflection effect of the body-air border of the lens. Presently, this optical solution, with its matchless parameters, stands on the front edge of modern optic.

5 IR illuminators, long range IR 11M, 12M Based on the LEDs with 870nm wave length. The main difference between these illuminators is the illumination angle: 30 or 80 degrees. The IR 11M has a close range angle of 80 degrees (up to 15 meters) IR 10M Provides a possibility to visualize objects up to 200 m with high sensitivity camera s. This illuminator also has a 80 degrees angle up to 15 meters, to spot nearby objects.
