Life cycle (h)
Life cycle (h)
The main characteristic for semiconductor-illuminants (LEDs) is their long life expectancy — as long as they are operated under very special condition. Unlike ordinary bulbs LEDs do nut suddenly fail, but gradually lose brightness during the course of their lifetime. Depending on the quality of the light-emitting diode this degradation may happen faster or slower.

The typical currency (mA)
is the currency, which creates the highest performance on your product, without damaging it. If the current will be decreased, also the performance of your product decreases. At high current the performance can as well increase, however the life duration decreases or the product will be destroyed. Therefore we do not recommend this.

SmartArray Dim2Warm Q3+1 2700K-2000K

The SmartArray series is a product line aimed at luminaire manufacturers. The series impresses with an outstanding price-performance ratio, high efficiency and excellent photometric properties.

The SmartArray Q3+1 Dim2Warm features another special feature. When dimming down, the colour temperature changes. This is done by an intelligent circuit depending on the operating current. This current variation is generated by most phase-controllable current sources with a phase-angle dimmer. When dimming down, this achieves a colour behaviour similar to that of an incandescent lamp - warmer light with reduced brightness. The great advantage of Dim2Warm technology is that no additional control unit is required.

The Nichia LEDs used in the 3-Step MacAdam binning provide excellent efficiency of up to 105lm/W. With a power of 3W, luminous fluxes of up to 305lm are achieved on the 13.5x13mm LED module. With this performance in the smallest possible space, the Plug&Play module can be used for a wide range of applications, from designer lamps to high-performance industrial luminaires. The cut-outs on the printed circuit board for screw fixing and the double-sided heat-conducting adhesive pad allow for easy and installation-friendly mounting.
