On September 9th, 2019 at 9 AM CT // 2 PM GMT: Join us as we host a webinar with Yiling Zhang, Technical Marketing Engineer, Automotive Microcontrollers and Processors:
NXP is a member of the ISLED alliance, an open alliance with the objective to provide an ecosystem - a complete system solution for automotive lighting - around the ISELED technology. This webinar will focus on using technology for next generation automotive & industrial LED Lighting Systems. Attend this webinar to:
- Learn Challenges of Ambient Lighting
- Get an Overview of ISELED Technology
- Learn about the NXP Solution to ISELED Technology
- You'll also Get to Watch a Product Demo of the NXP Solution to ISLED Technology
Attached are some resources to get the most out of your webinar experience.
The ISELED Concept
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 constantly opening up new areas of application. After outdoor lighting and dynamic backlight display, a new fieldbus is also under development. The ILaS (ISELED Light and Sensor) network will expand the capabilities of the current ISELED protocol so that not only LEDs, but also sensors and actuators in almost any number and combination can be controlled in the future. The ISELED concept integrates a dedicated microcontroller together with LEDs in a highly compact package. The controller contains the correction data for the individual color LEDs, thus eliminating the time-consuming ‘binning’ required up to now. Binning is a process by which LEDs are sorted according to their slightly different manufacturing properties in order to avoid visible differences in color and brightness in the application. This aspect is becoming ever more important with the increasing number of LEDs in vehicles that require the use of uniform LED components. ISELED can also be used to readjust the LEDs, taking into account the temperature variation and aging during 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 optimized 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 a 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.
ISELED technology for Automotive
The next generation of in-car lighting will feature hundreds of LEDs, typically in the form of flexible light strips each comprising many single RGB LEDs, which need to be individually controlled to produce dynamic effects. Each “digital LED” on the strip consists of a red, green and blue LED chip and the ISELED controller integrated in the same package. The digital LEDs can be daisy-chained. Up to 4,079 of them can be connected via a differential bus at a speed of 2 Mbps. They will be controlled by a single external master controller. This will effectively make new applications and lighting controls possible for applications where the relatively slow LIN bus is not suitable. With a data rate of 2 Mbit/s light effects at true video speed are possible with the ISELED system. With application software developed by an Alliance member, fascinating lighting effects may be created and simply controlled by an app on a smartphone.
