ams O STATIC RAMS 's next-generation infrared LED technology "IR:6"

IR:6 is a thin-film chip technology for infrared LEDs developed by ams O STATIC RAMS. It offers improved light output and efficiency compared to previous generations through enhanced light extraction performance, current diffusion, and heat dissipation. Product development is progressing for various sensing applications, including surveillance cameras, machine vision, facial recognition, and DMS (Driver Monitoring Systems).

IR:6技術の主な改善点

Improved light output and efficiency

Compared to conventional ams O STATIC RAMS infrared LEDs, this new LED offers up to 35% higher light output and up to 42% higher efficiency. Improvements to the chip surface structure, as well as enhanced internal reflectivity, allow for more efficient extraction of generated light. This results in higher light output at the same current, as well as reduced power consumption and thermal load for the same output.

Improved current diffusion and reduced forward voltage

In IR:6, the design of the n-contact (bond pad) has been improved to allow for more uniform current distribution within the LED chip. This improves current distribution, reduces the forward voltage (VF), and leads to improved efficiency for electrical input.

Red Glow Reduction Function

Some IR:6 products employ internal FILTERS technology to reduce red glow. By effectively suppressing wavelength components close to visible light within the chip, the phenomenon of the LED chip appearing red when lit (red glow) is reduced. This makes them suitable for applications where the light emission should not be conspicuous, such as in-car sensing and surveillance cameras.

Wide range of infrared LED lineup

ams O STATIC RAMS offers a wide range of infrared LED products for various applications, from automotive to industrial equipment.
You can select a product based on the required light output, wavelength, beam angle, and mounting space.

Wavelength selection based on camera sensitivity and red color perception

The IR:6 product line offers wavelength options of 850 nm, 920 nm, and 940 nm. This allows for selection based on the camera's sensitivity characteristics.
Products that reduce the "red appearance" when lit are also available.

Light output and light distribution according to application

We offer a lineup of products ranging from small packages to high-power types, with varying light outputs and beam angles. You can compare candidates according to your application, such as short-range sensing or long-distance illumination. When selecting, it is important to consider the required light quantity and illumination range separately. When illuminating a wide area or concentrating illumination on a specific area, you should consider the LED light distribution and secondary optical system in accordance with the camera's shooting range and the distance to the target object.

Extensive product series

ams O STATIC RAMS offers a diverse range of infrared LEDs with varying package sizes and light outputs. This allows for product selection tailored to application and design requirements, such as miniaturization of equipment and required illumination range. Here, we introduce two representative product series: the "OSLON Black series" and the "OSLON P1616 series."

OSLON Black: Features a variety of beam patterns and a red-effect reduction function, allowing you to select the appropriate option for your required illumination range.

System design advantages brought about by improved infrared LED performance

Improving the light output and efficiency of IR:6 is effective in considering power saving and space saving for the system while maintaining the necessary irradiation performance.
Depending on the product, driving conditions, and optical design used, the following effects can be expected:

  • Reduced drive current: Achieve equivalent optical output with lower drive current.
  • Reduction in the number of LEDs installed: By increasing the light output per LED, the number of LEDs required can be reduced.
  • Optimization of driver circuits and peripheral components: Consider optimizing the circuit and components by reviewing the drive current and LED configuration.
  • Reduced PCB mounting area: Contributes to space saving by reducing the number of LEDs and peripheral components.
  • Reducing the burden of thermal design: Consider simplifying the heat dissipation structure by reducing power loss while maintaining equivalent irradiation performance.

These effects do not necessarily occur simultaneously.
It is important to evaluate the entire system, taking into account conditions such as the required illumination range, light distribution, and operating temperature.

Various sensing applications supported by infrared LEDs

Infrared LEDs, when combined with cameras, are used as lighting for photographing objects or people.
Since the shooting distance, illumination range, and operating environment vary depending on the application, it is important to select a product that takes into account the required light output, wavelength, and light distribution.

Summary

To fully utilize the performance of infrared LEDs in a system, it is crucial to select products that take into account not only light output and efficiency, but also wavelength, irradiation range, mounting space, and thermal design.
ams O STATIC RAMS 's next-generation infrared LED technology "IR:6" can be used to explore power saving and miniaturization options tailored to your specific application.
