Home Services » About us Career Contact LED Lighting LED-modules mounted in a ceiling In-house designed LED dimmer The lighting industry is facing a new era of light sources where Light Emitting Diodes (LED) is the key technology. The major advantages of LED solutions are the long lifetime and the low power-consumption. To benefit from these advantages, understanding of the LED parameters, thermal aspects and driver electronics is required. LED selection LEDs are sorted in bin groups for their parameters. Terms such as CRI (Ra), chromaticity and flux and how this affects the light is essential. We have the knowledge to analyze and compare manufacuring data in a fair way for different operating conditions. Thermal calculations The thermal conditions of a LED directly affects the life time of a LED solution. To minimize the thermal resistance Metal Clad PCBs are often used as substrate material, however occasionally FR4 is used for products with less power dissipation. Driver electronics We can design drivers ranging from simple linear current drivers, to MCU controlled switched power supplies with features such as PWM dimming, DALI/DMX communication interfaces and fault monitoring. The driver electronics can be stand-alone or integrated on the LED PCB. Our Rapid Prototyping way of work cuts lead times for prototypes and evaluation versions of LED solutions. We can typically have fully assembled Metal Clad PCBs available to the customer in a few days. We are also hired to analyze aspects such as EMC in LED lighting solutions. EMC might not have been an issue in traditional lighting designs, but since LED driver electronics uses switched mode power supplies, EMC have to be considered in the design. We have regular contacts with the largest LED and semiconductor manufacturers to get updates about the market and future innovations. The market is growing fast and new LED products are released to the market rapidly. Address Br.
