Variants of embodiment


We offer the dimmer electronic ballasts for fluorescent lamps (DEB), which provide the lightdynamics in that devices, which use backlighting on fluorescent lamps.
One device (board) of DEB provides the supply and control of four fluorescent lamps. According to the lamp power are possible such variants as:
- DEB-4-18 for 4 lamps with the 18W;
- DEB-4-28 for 4 lamps with the 28W;
- DEB-4-36 for 4 lamps with the 36W.
If you want to control more than 4 lamps, you must use NDEB = Nlamps/4 DEB blocks and the external control unit.

Operating modes


Singleboard mode. In this case it's possible to connect not more than 4 fluorescent lamps of some power. In a standard performance an external microprocessor control unit of DEB provides the selection one out of eight control programs, which control these 4 fluorescent lamps. If you need, these programs may be changed according to some user's requirements at some fabrication stages.

Miltiboard mode.In this case it's possible to connect more than 4 fluorescent lamps of some power. You must use several DEB-boards ("number of lamps"/4) and an external control unit. If you use a standard external control unit, you can control 16 fluorescent lamps. If you need, you can augment the number of these lamps.

Variants of connection


WARNING:
1. To do installation when the power-supply system in "off" mode
2. To keep out a device from mechanical shocks.
3. To obey the common rules of work with electronic devices.

There are two possible ways of connection (depending on the number of fluorescent lamps):
- singleboard connection (when the control of 4 fluorescent lamps is needed);
- multiboard connection (when the control of more than 4 fluorescent lamps is needed.

1. Singleboard variant of DEB connection
In this case you can connect not more than 4 fluorescent lamps of rated power and you need only one DEB device for it.
The sequence of connection is following:
1.1. DEB board installation

Because of spray and moisture protectability of a board (it is already grazed) you could place it right at the light-box (it'll be desirable to do this from below) in a horizontal or in a vertical position, if you'll have enough place for this. The board must be fixed on the braces, which provide a gap between board and carcass, which is not less than 3 mm. The components of the board mustn't have any contacts with a carcass.

The choosing of the DEB's place of installation is determined by such considerations:

  • convenience of the wire connection from lamps and from net;
  • absence of a "blinding" from the board.

In that case, when the board installation in a light-box is impossible, you need to make a carcass. You can make it with the assistance of polystyrene. It is recommended to provide a height of the carcass not less than 50 mm. It'll provide the thermal conditions of a device. Besides that, you need to foresee the air ventages in a carcass (3 mm in diameter, not less than 20 ventages in the top of a carcass, equally on the whole area).
A carcass with a board could be installed within 20 meters from the lamps
Choosing the place of installation it is necessary to provide:

  • spray and moisture protection;
  • protection from a direct sunbeam hiting;
  • remoteness from a heat sources.

1.2. Lamp connection
During the choosing the fluorescent lamps, please, learn chapter "Parameters of the fluorescent lamps".
Lamps must be connected with a board with the assistance of the wires (or a cable) with a cross-section not less than 0,2 mm2 according to picture 1. The length of the wires (cable) must be no more than 20 meters.
During fixation and unfixation of the wires on a board you must keep the board from sagging. For that you must put a wooden or a polystyrene bar in a gap between a board and a carcass (where clip holders are placed) and to keep it there along the whole time of installation.
1.3. Choosing of the lamp control program.
With the assistance of the "jumps" (see picture 1) on the DEB board you must choose the appropriate control program for the lamps. To learn the list of the standard programs, see chapter "Standard control programs".
1.4. Net connection (220V).
To connect "phase" and "zero" wires in accordance with picture 1. To make a layout with the assistance of a wire (or a cable) with a cross-section, which is not less than 0,4 mm2.
After connection of a net, lamps would be lighted after 10 sec. of a pause, during which the preparation of the lamps for the first switching is happening.

2. Multiboard variant of DEB connection
In this case you can connect more than 4 fluorescent lamps of rated power and you need one control unit and "N" number of DEB devices (NDEB="number of lamps"/4) for it.
With the usage of a standard control unit you can provide the control of 16 fluorescent lamps. If you need, there is an ability to make a non-standard control unit for a work with practically unlimited number of lamps.
The sequence of connection is the same (like in a singleboard variant). But it has some differences. So, you must do points 1.1-1.4 taking account of that:

  • it is necessary to place some DEB boards and a control unit taking account of that the length of the cables (which are completed with a control unit) is 1 m.
  • choosing of a control program is provided by the jumps on an external control unit. At the same time, their position on the DEB boards is indifferent. To learn the list of standard programs of an external control unit, see chapter "Standard control programs".
  • it is necessary to connect the control unit and DEB boards by the control cables (which are completed in a delivery);
  • it is necessary to provide the layout of a net power not only for the DEB boards but for the control unit too.

WARNING: PAY ATTENTION FOR "PHASING" OF THE NET WIRES!
The example of a multiboard connection for 8 lamps is shown on a picture 2.

Lamp parameters


When you choose the fluorescent lamps, you must hold to such rules:

  1. The power of the lamps must be agreed with a power, which is calculated for the DEB boards. By individual orders it's possible to make DEBs, which are provided for the connection of the fluorescent lamps of a different power. For example, 2 lamps of 18W and 2 lamps of 36W.
  2. Temperature range of running of the lamps must be agreed with a temperature range of running of an advertising construction.
  3. The resistance of a filament of the fluorescent lamp must make up for about 3,5 Ohm (but not 6 Ohm). Otherwise, during their running, the filaments will overheat and it will make the lifetime of the fluorescent lamps shorter.
    You could make sure in it visually. After net switching of 220V, during the preparatory pause before the first switching on, when all the lamps aren't lighting, the filaments of the fluorescent lamps instead of being slightly visible, are highly heated. The absolutely majority of the fluorescent lamps, which were got by us, answer this parameter.

Standard control programs


In a standard performance an external microprocessor control unit of DEB provides the choosing of one out of eight control programs for 4 fluorescent lamps. If it's necessary, these programs could be changed for specific requirements of the customer at a fabrication stage. After changing the interdependent arrangement of the lamps you could get more and more combinations.
Table 1 shows the accordance of DEB unit jumps arrangement to the number of a program (picture 1). At the same time, the presence of a jump is pointed as "1", and his absence is pointed as "0"
After pressing the number of a program, you can learn it's algorithm (see picture 3). The number of a lamp is agreed with the number on the picture 1
Table 1 Accordance of "jumps" arrangement to the number of a program

Picture 3 Algorithm of a work of a program number in an independent mode

Standard programs of an external control unit are similar to the programs, which are shown in a table 1, with only one difference the state of the lamps is changing simultaneously in each of four channels by 4 lamps.
If the non-standard control programs are needed, you must create a control algorithm by under-mentioned example, using such marking: "1" switching; "0" not switching. At the same time it is necessary to point a cycle, taking into account that minimal cycle is about 0,25 sec. If the state of the lamps is not changing during some cycles, we could point *n in the next column (to save some place), where n the number of cycles, during which the state of the lamps has not changed. For example, during the cycle of a about 0.5 sec, the marking *4 should mean that in the next (0,5sec*4)=2sec the state of the lamps won't change.
Table 2 shows us the example of connection of the control algorithm for the case of a doubleboard connection (8 lamps). In this case the control is realized by 2*4 lamps (the state changes are taking place simultaneously in 2 channels by 4 lamps). Pay attention, that if you won't connect the lamps of one of the channels, you get a control program number 5 (see table 1).
