LIGHTING SYSTEMS Dynamic light with AUTO function What makes daylight unique is that it is dynamic, as the time of day and weather condition cause the light to shift in intensity and character. Dynamic lighting aims to replicate this natural daylight using two light sources - a warm and a cold one. The colder light serves as the effective lighting, suitable for activities like examinations and precision work, and the warmer light creates a pleasant atmosphere in the room, providing a welcoming ambiance. Numerous research reports highlight significant benefits for both productivity and health associated with dynamic lighting. To harness the positive effects of sunlight, even when spending extended periods indoors, D-Tec has developed a dynamic daylight function. Several D-Tec luminaires feature dynamic lighting, ideal for environments like dental clinics or examination rooms. With the dynamic daylight function, an attempt is made to imitate the temperature variations of the sun. The balance between warm and cold light can be manually adjusted. When the AUTO function is activated, the warm light will slowly (barely noticeable) fluctuate, simulating the temperature changes of the sun. To activate this function, press and hold the button on the remote control for 3 seconds. See Dynamic Light function table at max/min brightness/light temperature: (This however do not consider the difference between the diode direction. The horizontal diode direction for Leaf, Clair and Cloud offers a lot wider light distribution. The indirect light is also important to light up a room in a fantastic way. This is why for example a Clair, including indirect/dynamic light, is sufficient to alone light up a 15m2 clinic with shadow/glare free natural daylight) Facts and figures for D-Tec s portfolio regarding the "Dynamic light" feature Dynamic light is achieved when the warmer softer light source is added to the standard light.More total light!

Summary of dynamic lighting: 1. Improved working environment as it provides a varied light more like daylight. 2. Customers experience a warmer, more welcoming feeling upon arrival. 3. When working with composites, one can choose warmer light to eliminate curing. D-TEC AB Tel +46 31 969 302 Bank: Sparbanken Konto nr 8289-1, 24.406.038-0 Momsreg.
