Summary
Exhibitions and fairs – to whom
and for what? 3
The editorial talks about the purpose,
place and evolution of fairs worldwide, at
the same time writes about the upcoming
ElectroSalon exhibition and
ELEKTROkonstrukt conference.
Professional events 4
Springtime was rich on various professional
events. This time we include review on
the four probably most important ones.
Power engineering
Energetics
László Gruber:
Elemental power – stored power 6
The “fuel” for electronics devices is the
electric charge, the flow of which makes
the circuits operate. This electric energy is
produced in different ways, some of what
is described in the article.
Dr. Mihály Sipos:
Current sources
for mobile electronics 10
The article features two current source
solutions, specifically developed for
mobile electronics device current supply.
Imre Hizó:
Image processing basics – Siemens
illumination devices for industrial
image processing 12
Visual view can have its own build, just
like a crystal-lattice. The main goal is to
create an image from the view seen by the
camera that highlights the more important
parts and suppresses the less important
ones. The article discusses the realization
aspects of the illumination and optical system
of the image processing camera.
Ernõ Kollár:
Many of us use light bulbs,
but do we really understand it?
(Part 1) 14
There are multiple choices today to substitute
conventional light bulbs. Solutions
based on different working principles offer
greater light flux, more spot-like radiation,
lower energy consumption and maybe
other advantageous features. Have the
conventional light bulbs lost their glory,
there is no sense in making deeper analysis
with them? You may not be quite
sure…
Tibor Pálinkás:
Heating-analyzer current generator 17
The heating-analyzer current generator is
used to give analysis on equipments in
household electric systems (plugs and
80 info@elektro-net.hu
electric sockets), independently from the
tested appliance. The instrument's task is
to generate the stable alternating current,
flowing through the device under test and
responsible for its heating.
Miklós Lambert:
Useful advices from the distributor –
automotive LEDs are not
catalog goods 19
The automotive sector provides broad
range of LED application options, thus
creating a fascinating domain for advisoryexpert
distributors. As for RUTRONIK
Elektronische Bauelemente GmbH, a distributor
having many manufacturer relationships,
the automotive industry is actually
the largest buyer's market for the
whole range of LEDs. The automotive
applications offered by RUTRONIK cover
assembly backlighting, cabin lighting, display
backlighting, conventional and mirror-integrated
turn signals, third and “classic”
brake lights, headlights etc.
László Gruber:
LED – now in public lighting! 21
LED technology is still evolving: after the
red, green and yellow LEDs appeared on
the market, eventually the white ones followed
them. But if there is a white one
existing, why not use it for lighting purposes?
The article features the illumination
engineering uses of LEDs.
Components
Components
Miklós Lambert:
Component kaleidoscope 23
The kaleidoscope feature discusses active,
passive and electro-mechanic components
and module circuits from the offering of
many great international manufacturers.
Microchip site:
16-bit microcontrollers with
movable peripherals 26
The article presents a unique microcontroller
that does not assign peripheral
functions to dedicated pins unalterably,
but lets them to be relocated in a pin
domain. The newest, highest performance
member of the PIC18F J family will also
be featured in the article.
Siegbert Schaufelberger:
M32C87: a new extension to
the M16C platform 28
Market presents a need for higher and
higher performance, enhanced feature set,
larger scale integration solutions, all this
with a reduced power consumption for
new applications of course. Answer from
Renesas is the M32C/87 family, featured
in the article.
ChipCAD news 30
The Proteus PCB Design packages unite
the ISIS circuit schematic editor and the
2007/4.
ARES printed circuit board design programs
in an effective, yet easy to handle
design tool to support printed circuit
design. The article features the new version
of the professional design tool, the
Proteus v.7.
Gábor Turi:
New generation devices – Mentor
Components 32
With the rapid evolution of semiconductor
technology, many consider electromechanics
as an obsolete technique, in
spite of the fact that there actually is largescale
evolution. First of all, automated
manufacturing technology and the need
for cost-effective solutions created the
new generation of electromechanic components.
Our article gives a glance at
these.
Distrelec GmbH:
Competent customer service for
Hungarian Distrelec customers 33
Distrelec component distributor
announced the availability of its
Hungarian customer service to support
Hungarian customers. Above this, the
usual catalogue expansion is also
announced.
Dr. László Madarász:
Switching mode DC/DC converter
using IC and modules
(Part 2) 34
The second part of the series features
exactly a dozen converter types, then discusses
viewpoints that help to choose the
correct type.
Lóránd Szabó:
CODICO news 36
CODICO's news heading presents this
time high-power, 220 V LEDs from Seoul
Semiconductor and amorphous solar cells
and photo sensors from SANYO.
Zoltán Kiss:
Current regulative diodes 38
Several electronics circuit requires current
limiting. This is somewhat easy to solve
with CRDs (Current Regulative Diodes).
The article presents solutions and Semitec
products.
Automation and
process Automation, control

Harm Geurink, Levente Orosi:
Innovative goods depot for
deep-frozen goods storing at
the C. van Heezik company – with
the most state-of-the-art automation
technology from Phoenix Contact 41
The application presented in the article
justifies the reason for existence of new
technologies such as PROFINET and
Bluetooth. Phoenix Contact is one of the
leading developers for these technologies.
The article presents the complete system.
