QLAMP 111 Retrofit
LED Bulbs
Questo modello rappresenta il massimo della tecnologia delle lampadine retrofit. Grazie a un innovativo circuito a rifasamento
elevato è possibile utilizzare QL111 come se fosse una lampadina.
Le migliori prestazioni si ottengono utilizzando un alimentatore a 12V DC stabilizzato per LED , in questo modo si garantiscono stabilità
del flusso luminoso e riscaldamenti contenuti. Si può anche alimentare con trasformatori toroidali ed elettromeccanici lamellari con una
buona resa luminosa e con la possibilità di regolazione sul lato primario. Il collegamento con impianti muniti di trasformatore elettronico
è possibile rispettando il carico minimo del trasformatore elettronico che deve essere adeguato al numero di lampadine AR111 collegate.
La regolazione con dimmer ( 10..100%) è possibile ma dovrà essere rispettato il carico minimo del dimmer posto sul lato primario del
sistema .
La stabilità del flusso luminoso e il riscaldamento sono influenzati dall’alimentazione: alimentatori elettromeccanici o elettronici con
tensione di uscita particolarmente bassa rendono le prestazioni inferiori a quanto dichiarato in tabella. In caso di nuovi impianti si consiglia
di alimentare in corrente continua 12V -+3% l’apparecchio , in questo modo avrà una durata e una resa luminosa garantiti.
This model represents the best technology in retrofit bulbs. Thanks to an innovative high power factor correction circuit, you can use
this bulb as a normal halogen lamp.
The best performance is achieved using a stabilized power supply for 12V DC LED, this will ensure stability of the light and a reduced
heating. You can also use toroidal and electromechanical transformers with a good light output and the possibility of dimming on
the primary side. The use in already existing installations with 12V AC electronic transformers is possible but the minimum load of the
transformer must be taken in due consideration. The transformer must be sized to the number of AR111 LED bulbs connected . In most
cases, a transformer with a minimum load of 20W can drive a AR111 LED bulb but some transformers have instabilities and the minimum
load must be respected by connecting two or more AR111 LED bulbs. Dimming (10..100%) is possible but the minimum load on the
primary side of the dimmer must be respected.
The stability of the luminous flux and heating are influenced by power, electromechanical or electronic power supplies with very low output
voltage can reduce the performances of the AR111 LED bulb as stated in the table below. In case of new installations we recommended to
drive with 12V DC - +3% , in this way the lamp will have a long life and maximum light output will be guaranteed.
