Useful materials

1) divided by Dimming control method
a) An adjustable DC voltage
Typically used when the space in between the control device (dimmer) and a small lamp, and no more than 5-10 meters. This method is used, but is not widely used, because of their shortcomings.
Usually this method is used in small control distances, and to increase the distance special amplifiers are used, which are calculated on a certain area (must be considered as the distance and configuration arrangement luminaires, and the number of lamps that can be connected to a single dimmer or amplifier)
Use both single-channel and multi-channel controller for control. The controller, in this case, should support this technology dimming.
If required to increase the distance, it is associated with increase in the number multiple interface devices and gain control signal, which are cascaded and are divided into different signal portions.
This in turn creates difficulties with the implementation of large circuits with a large number of managed devices and the difficulty of the implementation of this method in relation to the long distances, which made management.
In general, in the case of control circuits for small over short distances.

b) pulse-width modulation (PWM)
The most optimal way to manage, which allows to realize a wide range of functions, as well as to provide a clear control, including over long distances. This signal can control lights at a greater distance, and the order of: 50, 100, sometimes 200 meters. To increase the distance of possible use of special amplifiers.
PWM signal has a number of features, including a large transmission distance, high resistance, the ability to manage the complex by this signal, the smaller the diameter of the wires required to transmit the signal.
For PWM signal, there are a greater number of controllers and the greater their diversity, allowing even the most complex control algorithms and functioning.
Shim allows you to use an integrated control signal, and control not only the brightness of the same color (mono-KOLOR), but also full-color (RGB).

Controllers can support both:
- Manual control (via buttons located directly on the controller)
- Remote (via remote control - infrared or radio)
- Remote by connecting to a computer having software, and perform certain control algorithm, laid down in advance in the memory, and with the specified parameters.
For example: controller, connected to the computer, can have such software. Perhaps the programming mode of the lamp during the day or during the week, month, year. It can be programmed with different brightness, and change the settings under certain seasons: summer, fall, winter, spring (since different lighting may be required at different times of the year).
And an optional variant, the controller can be controlled via the Internet (if you want to implement remote correction or control)
Also, as an option, it is possible to replace the wire along which the control - the wireless data transmission technology. In this case, no need to lay the wires on the ground or hang them on supports or structural elements of buildings.

Each controller and amplifier, and other accessories are designed to connect a certain number of lamps that can be controlled.


a) DMX
DMXpredstavlyaet an address management system, in which each user signal (or adresumoe or response device) has a fixed or variable fixed programmatically or via the address switches)
Knowing this address, can be addressed to a specific set of commands (to enable, disable, change the brightness level, color changing luminaires for RGB)
Usually it DMXmozhet be integrated to a voltage control system, DC and PWM control system. Most of the best and most popular - a combination of DMX superstructure cShIM control system.

DMXpredlagaet advanced capabilities for management. Allows you realize not one but several functions for each lamp. Due to the presence of DMX interface can be controlled by a computer with special software. This software can be programmed to work lamps, both in time and in the days of the week, months, seasons, and also create and burn custom special operation scenarios.

A typical example:
Each year has four seasons. Each season is characterized by: its duration of daylight and different lighting. Under each season, you can create an individual operation program, for additional energy savings and maintaining comfortable lightingDistinctive CCA tures DMX: - Administration- address a large number of managed devices or groups of devices-mnogozadachnost- opportunity programming at the control with the help of computer- flexibility use- can be integrated into larger systems using a cascading and also the ability to integrate with other sistemami.- economical to operate and maintain - intuitive easy principles control- perenastroykiPrimechanie: as an alternative to a wired control - possible use of remote wireless methods, such as wireless data transmission channel, WiFi, Bluetooth, optical, infrared, optical - laser. Or the possibility of remote transmission of data over networks supply 220V or 380V, or via a network Internet.Vse these remote methods can be used as add-ons to the 1, 2, 3 control methods or their kombinatsiyam.My invite you to familiarize yourself with our selection of interesting articles about LED lighting.
