Lights Control from eHouse smart home

eHouse LED – Home , building , Apartment powered by a voltage of 12 volts

With the continuous development of electronics, we can dispense with the traditional lighting 230V, which has a number of disadvantages in relation to the low-voltage lighting operating at constant currents.

  • disturbances and surges often seen with the naked eye
  • lower strength of lamps and ease of damage from surges
  • less efficiency at the same power supply
  • risk of electric shock raise in areas with high humidity, indoor and outdoor special as saunas , swimming pools , etc.
  • operating frequency of 50Hz felt like blinking, makes eyes tiring ( especially when dimming )
  • frequent damage of the lamps at the switching on, particularly halogens , fluorescent , energy-efficient lamps
  • high power consumption and surges at startup
  • large network interference generated by switching of fluorescent lights
  • the ability to switch off the safety fuses in such cases
  • Long start time , warm up to reach full light of most light sources
  • changes in light levels due to voltage instability, matting bulbs under high temperature, burning of gas in the fluorescent lamps
  • change color of 230V LEDs lighting and fluorescent as a result of operating variables

Most of these drawbacks can be eliminated by supply constant voltage (low) to lamps ( 12VDC power supply) .
This requires resignation from some sources such as fluorescent , fluorescent lamps , gas , etc. .
Classic lights as incandescent or halogen it is difficult to use, due to the very large currents needed to obtain the required power of light illumination. It also requires the use of much thicker wires, supplying power to reduce energy losses and voltage drop on wires .

Nowadays, the best kind of lamps suitable for this application are LEDs in various forms and enclosures .
The development of LED lighting technology, considerably larger amount of solution in relation to all other types of lamps. This ensures complete home lighting, on a plot using a very efficient and durable LEDs and LED RGB component lighting, controlled directly from eHouse home automation system known as building management or intelligent home .

LED lighting control and power LEDs with a constant voltage (12 Volt) allows you to :

  • achieve energy savings on lighting the building of more than 500 %
  • achieve maximum luminous efficiency and productivity
  • obtain a fixed color of the LEDs
  • significant extension of time LEDs
  • no interference and flashes comparing to Power frequency 50Hz witch tiring eyes
  • smart home control electronics directly from eHouse system without installing relays inclusive high-power devices
  • feasibility of emergency low voltage power supply, eg
  • a large number of lighting provides uniform lighting level and individually enable independent lighting groups/scenes depending on the current demand
  • implementation of safe and trouble-free lighting in wet locations , outdoor , in the saunas , pools , etc. .
  • facilitate installation, without the use of lighting fixtures and housings, watertight luminous self-adhesive tapes
  • rapid return on investment for the installation and lighting costs

LEDs can successfully implement a complete lighting most of the rooms , plot , driveways and can be used , among other things:

  • the main lighting ( and decentralized multipoint ) instead of the central
  • bedside
  • discrete
  • ornate and decorative lighting
  • stairway lighting , paths , routes , terraces , building , gates , wickets , input , emergency exits , halls
  • safe lighting for: pools , trays , saunas , conservatory
  • lighting images , furniture , cabinets , dressing , ornamental Sites
  • sconces
  • bedside lamp
  • lighting countertops , tables , jobs
  • television back light
  • lighting attics , compartments
  • Accent lighting

The main features of diode LED lighting

  • point character (small angle ) LED lighting
  • low power light in comparison with the classical lighting
  • requires a large amount of LED light points to obtain uniform illumination and the desired level of brightness over the entire surface of the room
  • requires a large number of independent lighting circuits
  • a large variety of lighting , color , adjustable brightness

To achieve high functionality and ease of use LEDs lighting ,it is necessary to take into account their characteristics, using these light sources .

  • it is necessary to use home automation enabling optimal lighting control with smart home controller – with a large number of control outputs or for Ethernet smart home controller
  • it is necessary to create a large amount of different light scenes and high -density LED lamps
  • Automation is required to simplify control and allow fast reconfiguration scenes, programs, without having to switch cables
  • the use of infrared remote control in order to avoid a large number of switches
  • the ability to automatically turn on light scenes such as night lighting , decorative , etc..
  • ensure a good power supply , voltage stability and control to enable long-life work without flickering , light color change , etc..

Ideal for controlling low voltage LED lighting drivers in rooms, eHouse intelligent home system are suitable ( RoomManager, EthernetRoomManager ), which have a large number of outputs to control lighting and other functions of the house or room ( max 24 + 3 dimmers ).
Lighting scenes can be independently configured using a PC and group programs or individual switch . drivers
These centralize and control all elements of lighting, heating and electrics in the room using one IR remote controlled device.
Application of Room Controllers to lighting (with LEDs) and heating (individual for rooms), allows refund eHouse home automation system within 1 year of installation considering electricity consumption.

Application of low voltage (12V) installation allows for independent execution of this part of the installation without the help of a qualified electrician and does not require controls and formalities relating to the registration of the building. In addition, the use of 12V lighting ensures complete safety for use in areas exposed to moisture or flooding and extreme temperatures , electrical shock, safe for children.

home Automation is based on a Room Controllers , which may be managed, eg:

  • Sony IR remote control (standard SIRC ) , universal remote , control panels
  • PDA , mobile phone , smartphone , touchphone
  • PC , PAD , wall panel
  • Web browser , FTP
  • standard electrical switches
  • automatically following the detection of motion in the room or too dark

RoomManager is an advanced microprocessor controller optimized for control rooms . eHouse home automation system (LAN and RS-485) Architecture based on RoomManagers, which is cheapest in the market due to the large amount of hardware resources in a single controller as opposed to systems built with “small blocks” incorporating “modems”.
Each RoomManager can be configured from a PC according to the individual needs of the investor for the room .

RoomManagers can control , among other things :

  • heating ( up to 7 independent segments )
