Automotive lighting reveals the identity of a car and produces the car’s first impression at night. Also, newly developed car models often feature new automotive lighting designs. In addition to making a good aesthetic impression, automotive lighting can also indicate a driver’s intention to change direction or show whether the brake is engaged.

LG Innotek employed its proprietary “LED lighting structure design technology” to achieve the ultra-slim line lamp “Nexlide-L”.

“Nexlide-L”, a Flexible Design Component

In addition to enabling straight lines, according to the design concept, “Nexlide-L” can form various shapes also including curves, and waves.

Further design flexibility can come from the ability to customize the brightness of the product according to its application and mounting position. The lightings can be designed in a variety of ways to produce, for example, red light for brake lamps and center, high-mount stop lamp (CHMSL), yellow light for turn signal lamps, side-view mirror lamps, and white light for position lamps.

The module boasts excellent luminous efficacy to produce a bright light of up to 7,500nit(cm/m2). This high brightness level meets the brightness required for brake lamps, therefore, the component can be used for automotive brake lamps.

An LG Innotek official said, “The Nexlide-L is a lighting module that can enhance the design, quality and safety of a vehicle at once.” He added, “Car manufacturers and drivers will be satisfied with the high-quality lighting component.”

TOF Applications Enabled with Lumileds Luxeon IR LEDs Operating at up to 40 MHz

Engineers from Lumileds and Melexis have demonstrated the operation of Luxeon IR LEDs at up to 40MHz, enabling Time-of-Flight applications in 940nm and 850nm with a range of up to 3 meters. According to Lumileds, the inherent properties of the Luxeon IR LEDs produce the clean and repeatable response curve required for TOF operations.

Lumileds and Melexis demonstrated Luxeon IR LEDs at up to 40 MHz for TOF applications.

Lumileds and Melexis demonstrated Luxeon IR LEDs at up to 40 MHz for TOF applications.

Erno Fancsali, Director CPAT EMEA at Lumileds stated, “The illuminator evaluation kit developed by Lumileds reduces the rise and fall times of the light pulses to 6 ns, which is a factor of 4 over other similar LED devices.”

Fancsali indicated that this reduction comes from optimizing the combination of the improved peak current response of the Luxeon IR LEDS, the PCB design, and the boost electronics. Fancsali further said that the illuminator card enables an LED-based TOF system with the range and accuracy comparable to VCSEL-based solutions. However, he says that the LED-based TOF system has a lower overall system cost.

“This break-through in high-frequency operation of Luxeon IR LEDs enables new TOF applications previously limited by cost or eye-safety constraints. This development will help to bring affordable and eye-safe distance measurements to a much broader range of products such as driver monitoring systems, logistics navigation, gesture recognition systems and drones,” Fancasali said.

The Lumileds LED illuminator comes in 60°, 90°, and 150° fields of view and for 850nm and 940nm wavelengths, by request, according to Wouter Schrama, Sr. Product Manager for the Luxeon IR Family at Lumileds.

“The joint evaluation kit with Melexis can help our customers reduce their development time significantly and enable them to successfully enter the market,” Schrama said.

“The Lumileds solution pairs well with our new Automotive QVGA TOF chipset and will help accelerate the adoption of TOF systems, at an affordable cost point; the performance of the system in terms of range and accuracy provides a compelling value proposition for the emerging TOF systems,” said Gualtiero Bagnuoli, product marketing manager at Melexis.

Archipelago and Seoul Settle Patent Disputes

Seoul Semiconductor based in Ansan, South Korea, reported that it and Seoul Viosys Co., Ltd. have resolved two patent infringement lawsuits it filed against Archipelago Lighting, Inc. in the U.S. Federal District Court for the Central District of California. Archipelago sells LED bulbs.

In 2017, Seoul filed the company’s first patent infringement lawsuit against Archipelago for the alleged infringement of twelve LED patents covering various aspects of Seoul’s long-established Acrich technology. A few months afterward, Seoul filed a second patent lawsuit against Archipelago accusing the company of selling additional products that infringe eight other Acrich technology patents.

In the lawsuits, Archipelago acknowledged that several third-party suppliers produced the LED components in its LED bulbs. Although Archipelago admitted that the company had no knowledge of any Seoul Semiconductor patents, it did not dispute that the LED bulbs in question infringed Seoul Semiconductor’s patents. According to Seoul, Archipelago also did not dispute the validity of the relevant its patents and agreed to pay a license fee as part of its commitment to respect the intellectual property rights of others.

Court Ruled in Seoul’s Favor Due to Archipelago Admissions

The California Central district court ruled in favor of Seoul Semiconductor in these cases based upon Archipelago’s admissions. Seoul’s asserted patents include technologies for LED chip fabrication, LED epitaxial growth, LED packaging, filament bulb LED structures, LED drivers for high-voltage operations, and Acrich MJT (multi-junction technology) for high power LED chips operating at 6V.

Seoul Semiconductor--Archipelago patent dispute diagram

Seoul says its Acrich technology enables high-voltage operation with a high power output using only a small number of LED chips. Specifically, Acrich technology employs the company’s proprietary LED driver technology to enable high-voltage operation, as well as its proprietary MJT technology for mounting and integrating numerous LEDs within a small area. Seoul says this arrangement maximizes the available space in LED products and increases power efficiency by 20%. Also, Seoul says the space saving design aids a simple circuit design and significantly reduces the size and cost of LED products.

Nam Ki-bum, executive VP of the lighting department at Seoul Semiconductor, said, “While Seoul will continue enforcement actions to prevent unauthorized use of Acrich technology, we will offer a license program with reasonable terms for companies that recognize and respect the value of Acrich technology. This will promote the distribution of innovative technology products in the market.” He added, “For young entrepreneurs and small entities that wish to pursue technology innovation, this will help them achieve business success, while Seoul continuously works to encourage a fair competition market where intellectual property rights are respected.”

Tridonic Releases Fifth Generation of LLE ADV5 Linear Modules with Up to 200 Lumens Per Watt Efficacy

Tridonic of Dornbirn, Austria, has released the fifth generation of the 24 mm LLE ADVANCED modules for linear luminaires and panel lights. The new modules boast efficacy of up to 200 lumens per watt. Tridonic says that the improved quality and efficacy of the LED modules results from a combination of the production and procurement process, and the company’s chip selection and binning based on optical criteria.

Tridonic cites its rigorous procurement and production process, which only uses premium raw materials as one of the reasons for the high quality and high efficacy of the LED modules. The company also says it bases its binning and chip selection on comprehensive testing and stringent optical criteria, which the company claims far exceed the usual standards. The resulting improvements thus boosted the efficacy of the fifth generation LLE modules up to 200 lumens per watt in the high-efficiency portfolio and up to 190 lumens per watt in the standard portfolio.

All of the new modules also come with a color rendering index above 90 or above 80, both as SELV and non-SELV variants. Tridonic asserts that the modules give designers greater flexibility now that it is also possible to combine SELV variants in different lengths, while the light output remains entirely homogeneous. Also, the company notes that the lengths and drill holes according to ZHAGA requirements allow integration into existing designs.

Wide Range of Applications

The new LLE modules are compatible with existing accessories for linear luminaires, including ACL linear lenses with light distributions, mounting clips, end caps, and covers. With the appropriate covers, the modules can even be used right away as luminaires, according to Tridonic.

The company says that combining the modules with a suitable LED driver (either fixed output or dimmable) creates a highly efficient system for a broad range of applications. The LLE modules come in different lengths and with color temperatures of 2,700 K, 3,000 K, 3,500 K, 4,000 K, 5,000 K, and 6,500 K. Also with the right dimming driver, Tridonic asserts that the respective color temperature remains constant even when dimmed. The modules feature a projected service life of 72,000 hours, and Tridonic backs them with a five-year manufacturer guarantee.

LG Innotek Promoting the Addition of Violet LEDs to Lights for ‘Visible Disinfection Lighting’

LG Innotek based in Seoul, South Korea, announced the company’s ‘Visible Disinfection Lighting’, a functional light source that sterilizes like sunlight. According to the company, its special violet (405nm) LED achieves eco-friendly sterilization. LG Innotek says that the method is analogous to drying household goods and blankets in the sun. Instead of occurring in the sun, however, the sterilization happens with exposure to violet LED light indoors.

LG Innotek -- 405 nm wavelength (violet) LED package for 'Visual Light Disinfection'

LG Innotek — 405 nm wavelength (violet) LED package for ‘Visual Light Disinfection’

Long-term exposure to sunlight makes bacteria unable to reproduce, thereby causing their extinction. This process is due to a material called ‘porphyrin’ within bacteria which destroys its cells after reacting with certain wavelengths of sunlight. LG Innotek employed 405nm wavelength (violet) LED light to which porphyrin reacts most actively, using the company’s unique light extraction technology.

Tests Prove ‘Visible Disinfection Lighting’ Kills Bacteria but Safe for Humans

Korea Conformity Laboratories (KCL) confirmed that Hygenic Light LED killed 99.9% of Escherichia Coli (E. Coli) without any chemicals. LG Innotek notes that the sterilization function can be used where many people pass by such as kitchens or restrooms because it does not harm humans. Furthermore, the International Electrotechnical Commission found that the light meets the Photobiological Safety Standard (IEC 62471) because it does not have any negative effect on human eyes or skin.

Also, the company says that its ‘Visible Disinfection Lighting’ can optimize the sterilization power through the control of the light’s intensity (brightness).

Product Could be Utilized in Facilities for Health & Medical Treatment and for Food & Drug Facilities

LG Innotek intends to actively promote ‘Visible Disinfection Lighting’, targeting local and international LED lighting makers. The company says that the proven sterilization effect and safety of this product allow it to actively promote the product for use in facilities related to health & medical treatment as well as public places including food & drug-related facilities and public restrooms.

Already, as a trial, LG Innotek has installed this product in the coffin rooms of funeral halls and waste storage rooms in Yonsei University Severance Hospital in Seoul. The company has received positive responses about the product as it enhances the sterilization effect.

Song June-O, the Vice President of LED Business Unit, said that “‘Visible Disinfection Lighting’ is an innovative solution that will brighten up our living space and at the same time sterilize it safely and conveniently.” He added, “It will be able to improve the quality of many people’s lives.”
