R&D Activities

-The Company pursues "the five values of light", which are creating light, detecting and recognizing through light, freely obtaining information through light, making use of light energy, and rendering a scene with light.

-Advancing and integrating core technologies (light distribution, design, CAE, circuits, control, light source, process innovations)

-Major areas of R&D activities:

  • Opto-electronics: High-output white LED, high-output red/infrared LED, high-speed/highly sensitive image sensors
  • Displays: ultra-high contrast LCD, fiber micro scanner, display drive circuit
  • Light source/lighting: automotive lighting, LED road-surface lighting devices, interior lighting devices, lighting drive circuits/power sources
  • Software/CAE technology: light-distribution simulator, tools for measuring the optimum shapes of optical devices
  • Materials and processing technology
  • Styling and design of products
  • Products in which the above devices and technology have been integrated

Product Development

Next-generation lamp system
-The Company develops a next-generation passing lamp system that automatically warns of the presence of vehicles at intersections during the night. The lamp system will check GPS data against map data to determine vehicle positions and automatically emit light when approaching locations like low visibility intersections. It will signal the approach of the vehicle to surrounding vehicles and pedestrians to prevent accidents. Stanley Electric envisions the system being used for autonomous vehicle-to-vehicle communications. The company aims to commercialize the lamp system by 2020.

-Kyoto University and Stanley Electric Co., Ltd. (Stanley Electric) announced that they have jointly developed a next-generation technology for white light emission. The technology enables the emission of strong white light without spoiling the directivity of blue light by utilizing nanoantennas, which enhance the directivity of highly diffusive yellow fluorescent light. The new technology is expected to be applied for products such as automotive headlamps. Kyoto University and Stanley Electric placed nanoantennas (aluminum particles) on a yellow phosphor plate that measures 200 micrometers in thickness, at intervals of several-hundred nanometers. The array of nanoantennas shape the yellow fluorescent light into the vertical direction, which arranges the direction of the yellow and blue light that transmits through the plate, and realizes a uniform mixture of light colors. When nanoantennas are used, light concentrates in the vertical direction, and light intensity is enhanced by 7 times. (From an article in the Nikkan Jidosha Shimbun on December 8, 2018)

-Stanley Electric Co., Ltd. (Stanley Electric)
announced on May 13 that its consolidated subsidiary, Stanley Tsuruoka Works Co., Ltd., will establish a new LED lamp plant in Tsuruoka City, Yamagata Prefecture. The company will invest about JPY 6 billion, and the new plant will start operations in May 2021. Stanley Electric will also establish a new research and development office in Yokohama City, and test facilities in Hadano City (both in Kanagawa Prefecture). The total investment will be about JPY 15 billion. The company will accelerate preparation for the advancement of connectivity, autonomous driving, electrification etc. (CASE). The subsidiary will acquire a site (58,200 square meters) adjacent to its existing plant to build a 16,600 square-meter plant. The existing plant will be demolished after the start of operations at the new plant. The new plant will produce conventional LED lamps that are currently produced at the existing plant, as well as next-generation products, such as high-power infrared LED lamps that offer visibility in dark conditions, and antibacterial UVC LEDs.
