Point light source LED

Point light source LED

◆ Strong and narrow light distribution pattern similar to parallel light, high output, high response speed ◆ Optical rotary encoder, photoelectric sensor, light source for optical fiber communication

◆ 650nm, 850nm, 860nm, 870nm Point light source LEDs have a special structure and are characterized by a strong and narrow light distribution pattern similar to parallel light. Therefore, they are used in applications such as light curtains and rotary encoders, and they also serve as alternatives to VCSELs. At DOWA, customization is possible according to customer requests, including chip and light-emitting part sizes. "DOWA Electronics" was established in October 2006 as a subsidiary of Dowa Mining, which started as a mining smelting company in 1884, specializing in electronic materials. In the LED business, we manufacture and sell high-quality deep ultraviolet (300nm to 340nm) LEDs and red to infrared (660nm to 1,650nm) LEDs. We also plan to release mid-infrared (3 to 5um) LEDs and red VCSELs soon.

Point light source LED

Point light source LED

Stable luminescent distribution! Suitable for optical encoders and photoelectric sensors.

The point light source LED handled by Rikei Corporation, manufactured by Daido Steel, contributes to the industry and market as a high-end LED for high-precision photoelectric sensors and high-resolution optical encoders. A point light source LED refers to a light source with a very small emitting area compared to a typical LED, meaning it is close to a point source. In a typical LED, light is emitted from the entire surface of the chip, whereas in a point light source LED, light is emitted from a tiny part of the chip (the emitting window). 【Features】 ■ High reliability ■ Small emitting window diameter ■ Stable Lambertian light distribution ■ Suitable for optical encoders and photoelectric sensors ■ Capable of achieving high resolution when applied to sensors *For more details, we would appreciate it if you could download the PDF file and refer to the materials. We will provide detailed materials regarding individual models. If you have any questions or concerns, please feel free to contact us.
