catalogue 2010 INFRA - RED ILLUMINATION
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
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: www.elenek.com.
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
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.
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.
The Elenek IR illuminators are built using first
quality infra-red spectrum Light Emitting Diodes
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
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
