Originally designed for dynamic ambient lighting indoors, where a large number of RGB LEDs on a light strip can be individually controlled by a local controller, the ISELED concept is continually opening up new areas of application. The ILaS network will expand the capabilities of the current ISELED protocol so that not only LEDs but also sensors and actuators in virtually any number and combination can be controlled in the future.
The concept combines a dedicated microcontroller together with LEDs in a highly compact package. The controller includes the correction data for the individual colour LEDs, therefore removing the time-consuming 'binning' needed up to now. The protocol can also be employed to readjust the LEDs, taking into account the temperature variation and ageing throughout operation. The correction data are determined by the manufacturer during the final test of the RGB LED and stored directly on the controller chip. The digital RGB LEDs can thus be operated with an optimised protocol without the previous overhead. A further boost for ISELED technology comes from automated/autonomous driving, where, in addition to displays, light will increasingly be used to transmit information and warnings.
A far-reaching development environment and the support of industrial partners are an essential prerequisite for the success of new trend-setting technology. Against this background, the ISELED Alliance was created. This alliance is an open industrial alliance with the objective of developing a comprehensive ecosystem – i.e. a complete system solution for innovative automotive lighting – based on ISELED technology.
The 'International Symposium on Automotive Lighting 2019', Lighting Technology Faculty of the TU Berlin, 23 to 25 September, is aimed at designers, engineers, scientists and decision-makers from the automotive lighting industry.
