Security High-power IREDs World-class high luminous efficiency
High efficiency: 610 mW/W
Low thermal resistance,
While being high-power, the heat generation has been considerably reduced
thanks to the package's low power consumption characteristics
Optimal light source
for night illumination and biometrics
Compact high-power IREDs equipped with a newly developed high-output, high-efficiency LED die with a low thermal resistance ceramic substrate. It is the best light source for camera night illumination support and biometric authentication. Recently, in the automotive field many cameras are being deployed for driver surveillance and automatic driving support; our IREDs can also be used as light sources in night vision applications. Our IREDs are optimal also for the security field, as a light source for security cameras installed indoors or outside. Our IREDs contribute to the downsizing of the final product, possessing high luminous efficiency and low heat generation; they can be used for biometric authentication of small devices, including personal computers and others.

Keeping heat in control when driving high current, thanks to low power consumption and low thermal resistance
Like high-power visible light LEDs, IREDs also have an issue related to heat for high power types. At high temperature conditions, not only the output drops but also the operating life is shortened, and in the worst case the LED may break.
Also, heat adversely affects the surrounding devices, calling for heat dissipation measures that require high expenses and space. In this series, by adopting an LED die with low forward voltage (VF), power consumption is reduced; moreover, by employing materials and structures that reduce the thermal resistance of the package, the heat generation is greatly reduced as compared with the equivalent product.
Compared with existing products, the heating value of these high-efficiency, high-power IREDs has decreased significantly, which contributes to the miniaturization of the entire module
The chart on the right compares our high-power IREDs (characterized by high efficiency and low heat generation) with the existing products in terms of substrate temperature. Since the rise in substrate temperature is small compared to the existing products, high density mounting and miniaturization of the entire camera module by reducing substrate area can be attained.
