Phasedimming

There are two techniques for phase-dimming: trailing edge systems (also called falling edge) and leading edge systems. With this way of dimming, there’s an extra device, the dimmer, connected to the main input of the power supply. No extra control wires are needed and you can add it to your existing installation(s). This option allows for dimming between 30 and 100%, depending on the type of falling edge dimmer you’re using. A few things to consider are: blinking may happen when dimming to a minimum, and not all of them are compatible with LED. Furthermore it is recommended to use a dimmer of the type trailing edge.

Back-illuminated sensors, also known as backside illumination (BSI or BI), hit the digital photography market ten years ago, offering significant image quality improvement in low-light situations. In this particular type of image sensor, imaging components are arranged in a manner that increases the amount of light captured: while traditional sensors have wires and transistors placed in front of the lens, BSI technology allowed for the placement of the transistor matrix behind the lens, which prevents illumination loss.BSI manufacturing was initially highly expensive, which restricted its application to specialized cameras for low-light conditions (such as security cameras). However, the considerable improvement in image quality – especially the reduction in digital noise levels – provided by backside sensors motivated the photography industry to invest in mass BSI production, resulting in lower costs.

Analogdimming

A low-cost installation that works with the push of a button, this provides perfect dimming in the 0 to 100% range. Things to keep in mind are the limited number of power supplies that can be dimmed with the same button ( max 5), this to prevent synchronisation problems and the need for 2 extra control wires.

This system makes for a perfect professional dimming method in the 0-100% light intensity range and allows you to preset lighting scenes when using home automation. It’s an analogue dimming technology in which a signal is given between 1 and 10 volts or potentiometer (100K linear). This requires two control wires between the power supply and the dimmer, a limited number of power supplies when using a potentiometer, and a main switch is needed to turn the lighting system on and off. A limited number of power supplies is allowed when using a potentiometer.

Wireless dimmers offer extensive possibilities for smart buildings. CTRL Delta, our wireless dimming technology, allows you to integrate all kinds of electrical devices into a wireless network. As a result, lighting can be controlled via smartphones, tablets, smart watches, push buttons, switches or the Xpress control panel. Smart control can even be done via existing wall switches without changing the wiring. Discover all advantages in the CTRL Delta product brochure.

Digital Addressable Light Interface (DALI) is a universal standard for digital dimming systems and one of the most frequently used, regardless of the project scale. Unlike the analogue light settings, it allows you to dim each device separately, as each power supply gets an address. This way each device can be controlled independently from the other. The lamps can also return signals, making it flexible and economical to adjust the lighting. Integration into building management systems is quite simple. As a leading company in lighting and a member of DiiA, we embrace new technologies: the transition to DALI-2 was a logical next step.

Sony introduced the first back-illuminated sensor developed for the consumer market in 2009 (the Exmor R CMOS sensor), and competitors soon followed suit by exploring similar sensor designs. Although Sony is to be thanked for introducing BSI to consumers, this technology is now widespread in the digital photography industry, having been embraced by every major brand. Nowadays, back-illuminated sensors can be found not only in high-end cameras but also in mobile devices such as smartphones and tablets.
