Collimating lens

This Application Note outlines the components needed to protect USB 3.1 devices and attenuate EMI that may cause the device to fail EMC testing. This will be demonstrated in USB Type-C dongle to characterize the effectiveness of the components.

New Type-H super high-power collimator LED sources with 30-50W emitters have been added to the product portfolio. These new collimator light sources produce a market-leading optical power output of up to 3.5W, which is up to 5 times from our existing high-power Type-B collimator LED sources. The LED emitters are mounted directly onto the metal base of the collimator which also features an integrated heat sink and a cooling fan. This configuration minimizes thermal resistance between the LED emitter and the heat sink resulting in better heat dissipation. The collimating lens can be adjusted if needed for precise collimation. A locking ring fixes the lens position after adjustment. The collimators have been pre-adjusted in the factory.

The new Type-H light sources are larger in dimensions compared with existing Type-A and Type-B light source. Please examine the installation drawings carefully. Power supply for the cooling fan is included in the price of the LED collimator sources. The LED collimators include a 1.5-meter cable with two bare-wire terminals at the end. The light sources can be driven by Mightex LED controllers or other LED controllers and current sources.

USB-C now offers different connector variants ranging from USB 2.0 in Type-C housing to Type-C for a 10 GBit data rate. The housing variants have also become more diverse. All these types have their special characteristics, which in many cases may already have to be taken into account in the layout. We would like to shed light on these points and identify ways of dealing with the challenges...

I am application engineer for EMI situation and power converter design for industrial- and automotive electronic applications. I am the company spokesperson for EMC seminars and held over the world, since 2005, approx. 500 seminars to design engineers, giving training to easy understanding the EMC problems at board level.

How to collimatelight

We support you in preparing your applications for these requirements. Our wide product range for USB-C includes connectors, EMC filter components, ESD surge protection as well as AC/DC and DC/DC converters to simplify your design-in and meet all legal requirements.

An LED collimator consists of a collimating lens and an LED emitter. The LED emitter is placed at the focal plane of the collimating lens. The collimating lens thus images the LED emitter into infinity. Mightex LED collimators employ a high-NA aspherical collimating lens for precision collimation and high light throughput.

IMPORTANT : (1) LED’s can ONLY be driven by a constant-current source, and NOT a voltage source (e.g. a battery, or a AC/DC power supply etc.); (2) Please always verify LED’s current rating first before applying current to the LED, and please always make sure NOT to apply current that is above the LED’s current rating.

From December 28, 2024, all mobile phones, tablets and cameras sold in the EU must be equipped with a USB-C charging port - from spring 2026, this will also apply to laptops. This new EU requirement aims to reduce electronic waste and make electrical appliances more sustainable.

At the end of 2024, the proliferation of chargers for small electronic devices will come to an end. The EU is making USB-C connectors and the USB Power Delivery standard mandatory. The European Parliament had already adopted this in October 2022 as an amendment to the Radio Equipment Directive and then passed it on to the member states for implementation into national law.

To bring inductive components closer to customers and users with their properties and applications in a practical way and without ballast - that is and remains the claim of the technical book ; “Trilogy of Inductive Components";. First published in year 2000, the book is now a standard work in many development departments and universities and has been sold over 30,000 times.
