1. RMA registratie
RMA registratie vindt plaats via email (rma@leddriven.nl).  Retourneren, verwisselen of reparatie kan alleen geschieden na melding van de RMA aanvraag naar het juiste emailadres. U dient minimaal de volgende gegevens aan te leveren eventueel aangevuld met foto's en andere relevante documentatie.

  • Product type
  • Serienummer
  • Datum van levering
  • Contactpersoon (naam, email, telefoonnummer)
  • Omschrijving van het defect (Een duidelijke omschrijving van het probleem, wat het verwachtte resultaat zou zijn geweest en de actuele condities waarbij het gebeurde)

2. LED driven antwoord
Wacht op ons antwoord per e-mail. Wij nemen uw aanvraag in behandeling en zullen u binnen enkele werkdagen berichten. Via de mail ontvangt u een RMA-nummer en instructies van ons.

3. Retourneren van uw product
Bij de retourzending van het product verzoeken wij u graag een kopie van de RMA aanvraag in de doos mee te zenden en het RMA nummer duidelijk op de doos te vermelden. De opgegeven RMA producten dient compleet en degelijk verpakt te worden om transportschade te voorkomen. Retournering dient te geschieden binnen 14 dagen na afgifte van het RMA nummer.

4. Verwerken RMA
Wanneer uw RMA in goede orde is ontvangen zullen wij uw RMA zo snel als mogelijk behandelen. Als blijkt dat uw product niet onder de technische garantie valt dan zullen wij vooraf de kosten opgeven. Zodra uw RMA gereed is voor verzending wordt dit altijd vooraf gemeld.

LED Wiki: DALI - Digital Adressable Lighting Interface
Standards for DALI
IEC 60929 and IEC 62386 are technical standards for network-based systems that control lighting in building automation. They were established as a successor for 0-10 V lighting control systems, and as an open standard alternative to Digital Signal Interface (DSI), on which it is based. IEC 60929 is the first version of the standard and will be withdrawn by 23rd of June 2014. Members of the AG DALI are allowed to use the Digital Addressable Lighting Interface (DALI) trademark on devices that are compliant with the current standard. Non AG DALI members can apply for a fee bearing licence.

A DALI network
A DALI network consists of a controller and one or more lighting devices (e.g., electrical ballasts and dimmers) that have DALI interfaces. The controller can monitor and control each light by means of a bi-directional data exchange. The DALI protocol permits devices to be individually addressed and it also incorporates Group and Scene broadcast messages to simultaneously address multiple devices (e.g., "Group 1 goto 100%" or "Recall Scene 1").

Each lighting device is assigned a unique static address in the numeric range 0 to 63, making possible up to 64 devices in a standalone system. Alternatively, DALI can be used as a subsystem via DALI gateways to address more than 64 devices. Data is transferred between controller and devices by means of an asynchronous, half-duplex, serial protocol over a two-wire differential bus, with a fixed data transfer rate of 1200 bit/s.

DALI requires a single pair of wires to form the bus for communication to all devices on a single DALI network. The network can be arranged in a bus or star topology, or a combination of these. The DALI System is not classified as SELV (Separated Extra Low Voltage) and therefore may be run next to the mains cables or within a multi-core cable that includes mains power. The DALI data is transmitted using manchester encoding and has a high signal to noise ratio which enables reliable communications in the presence of a large amount of electrical noise. DALI employs a diode bridge in the interface circuitry so that devices can be wired without regard for polarity. Signal level are defined as 0±4.5 Vfor "0" and 16±6.5 V for "1". Central interface power maximum is 250 mA and 2 mA per unit. The network cable is required to be mains-rated, with 600 V isolation and at least a 1 mm cross-section, with a maximum drop of 2 volts along the cable (max 300 m). Signal interface is galvanically separated and doesn't need any termination resistors.

Earlier generations of DALI devices stored configuration data in EEPROM, which was problematic due to the limited number of write cycles supported by EEPROMs. In current generations of DALI devices, RAM is used in preference to EEPROM during normal operation, which significantly reduces the number of EEPROM writes and thus extends their lifetimes. This use of RAM, however, is patented and therefore mandates payment of a license fee.
