Exclusive interview with Luminus: Fully serving the lighting market with high-quality LED light sources

In the current period when the LED lighting market demand is temporarily flat, LED lighting companies are actively pursuing a "two-pronged" strategy for development. With one hand, we will seize the household, commercial and other general lighting markets to stabilize our business; with the other hand, we will seize the automotive lighting, laser, UV disinfection, plant lighting and other fields to develop high value-added, high-volume, high-growth special lighting market segments.

With more than 20 years of industry experience, Luminus is also improving the quality of light applications by combining the high-end technology and innovative R&D teams of MIT and California's Silicon Valley, and based on the advantages of domestic epitaxial chips and other LED supply chains, and continues to bring high-quality product solutions to the general and special lighting markets, fulfilling the development concept of using photons to improve life.

During the 28th Guangya Exhibition, LEDinside had the honor to conduct an interview with Shao Jiaping, general manager of Luminus Asia Pacific, to explore how Luminus continues to stand in the LED lighting industry in an unpredictable environment through its own technological advantages and latest development plans, and continues to provide high-quality LED light sources to the market.

General lighting is heading towards higher performance, smarter and healthier direction

Luminus was founded in 2002 at the Massachusetts Institute of Technology in the United States. The company masters ultra-high current density technology and patents in the field of special lighting. In 2013, Luminus was acquired by Sanan Optoelectronics and became a subsidiary. Today, Luminus has become a well-known manufacturer of ultra-high power LED devices in the world.

Relying on the powerful LED epitaxial chip resources of its parent company Sanan Optoelectronics, Luminus can use different chips to match products that suit different needs. Through chip customization, Luminus can design high-end products with low current and ultimate light efficiency; it can also reduce product costs by optimizing chips. In addition, Luminus has developed a multi-junction multi-spectrum blue light chip through its own patented technology, bringing more comfortable full-spectrum products to the lighting market.

Mr. Shao said that judging from the situation of LED market terminals and downstream customers, the industry's demand for LED lighting continues to develop in the direction of higher performance, healthier and smarter. In response to these trends, Luminus continues to optimize LED general lighting products and develops multi-spectral light health technology, as well as corresponding chip and packaging products.

At this Guangya Exhibition, needles In response to the latest demands in the field of general lighting, Luminus demonstrated new COB and medium-power products for various scenarios such as outdoor, commercial, home, and hotels.

In the center of the exhibition hall, Luminus set up an outdoor scene check-in point to demonstrate the application effects of mid-power products MP-2835, MP-3030, MP-5050, and MP-7070. This series has a light efficiency of up to 240lm/W+, flexible color temperature, CRI selection, perfect power performance coverage, high reliability and other advantages, meeting the needs of outdoor high-performance outdoor/street lighting, industrial and horticultural applications.

In high-end markets such as commercial, Luminus's LUX COB series relies on GE's patented KSF phosphor technology to achieve the highest typical light efficiency value >160Im/W, achieving significantly high color quality, such as the lowest 90 and 95CRI, high R9 and excellent TM-30 value, providing high luminous efficiency for directional lighting sources.

The Gen 6 series is Luminus' sixth generation COB product, which uses nitride phosphors to provide high reliability and a wide efficiency range. Luminus' two major series of products bring high-quality lighting output to high-end customers.

The High Density Gen 4 series of high-power density, small-angle lamp designs; the COB lighting Hospitality light color series with high light efficiency and light color control; the gold jewelry customized light color scheme that can set off the color texture of gold and achieve better light color consistency, etc., fully covering the use needs of various high-end commercial scenarios.

In addition to various LED products with high CRI, high luminous efficiency and high color reproduction, Luminus also focused on displaying smart and healthy lighting product solutions. Including: three-channel COB dynamic dimming intelligent control scheme that realizes color temperature adjustment along the black body line; Smooth White product series that provides sunlight-like color expression, no UV, low blue light, complies with WELL building standards, focuses on humanistic lighting, and provides users with a close to full-spectrum lighting experience; humanistic lighting Salud Mid Power series that can keep living things full of vitality, etc.

Mr. Shao pointed out that in the future, general lighting will be further integrated with intelligent systems and human-centered health lighting technology to improve lighting quality.

Mr. Shao pointed out that Luminus has achieved good results in the fields of medical treatment and projection in the past. Now Luminus will deploy in more LED subdivisions with development potential, and automotive LED is one of the key directions.

LEDs are widely used in automobiles. LEDs are used in interior ambient lighting, HUD head-up displays, exterior headlights, taillights, and the latest projection lighting technology. In recent years, with the rapid development of the automobile industry in the direction of the new four modernizations, the scale of the automobile market has been growing day by day, which has brought promising development space to the automobile supply chain including the LED industry.

Facing the vast automotive LED market, Luminus relies on more than 20 years of professional experience in LED projection systems and is committed to developing LED chipsets that meet automotive standards and mainly plans three major categories of products.

The first is to use the reliability and rich multi-spectral solutions of Luminus to create interior atmosphere lights and external turn lamps; the second is to use DLP projection technology to realize the starry sky ceiling in the car and the augmented reality-level AR HUD application; the third is to create high-scoring external lighting High-resolution pixel headlights carry dynamic ground projection effects.

Mr. Shao revealed that Luminus’ automotive LED business is currently progressing smoothly. Projects for AR HUD, Mini LED for integrated through-taillights, and Micro LED for pixelated headlights are close to being finalized and under negotiation. Conventional automotive LED devices have been shipped in batches to domestic leading new power car companies. Looking forward to the future, Luminus hopes to accelerate the localization process in the field of automotive LEDs, allowing more brand car companies to experience the charm of Luminus' automotive LEDs.

On the other hand, laser is also one of the new niche markets that Luminus focuses on, and it officially entered the laser field this year. Luminus has now launched green (520nm) and blue (455nm) laser diodes, which are packaged in TO-56 and equipped with photodiodes. The output powers are 80 and 100mW respectively. The products can work efficiently in pulse and CW modes and support high-speed modulation.

Product applications cover laser lighting, laser projection display, level measurement, biometric monitoring and health. In the future, Luminus will also be involved in laser The field further explores opportunities for domestic substitution.
