Osram Opto Semiconductors, a German LED chip manufacturer, is actively participating in infrared LEDs (IR LEDs). Recently, the SFH 4703AS infrared emitter has been added to the high-power infrared LED product line. The wavelength of the emitted light is 810 nm. The new infrared LED enhances image contrast and enhances the performance of surveillance and image sensing systems, such as the application of license plate recognition, regardless of day and night, the recognition is very high. In addition, because the image sensor is more sensitive, compared with a camera with a wavelength of 850 nm infrared LED, the visible range of the LED lamp is unchanged, and the visibility range is larger. High image contrast facilitates analysis Cameras or cameras that typically use 850 nm and 940 nm infrared LEDs typically do not produce high contrast images when certain colors are recognized. The SFH 4703AS infrared LED introduced by OSRAM has improved this shortcoming, so it is especially suitable for applications that require excellent image contrast, such as an automatic license plate recognition system installed at the toll booth or parking lot entrance. Because this infrared LED enhances image contrast, the system is faster and more accurate when identifying license plates, reducing driving waiting time. In addition, this product can also be applied to traffic monitoring systems and CCTV surveillance systems. Same optical output with larger line of sight Another advantage of the new infrared LED is its high spectral sensitivity. When using the same lumen output source, the 810 nm infrared LED is far better than the traditional 850 nm or 940 nm sensor. If you want to maintain the same range, the new infrared LEDs are designed to reduce the number of components. However, it must be noted that the infrared light seen by the average human eye is a mild red light source, while the infrared light of 810 nm is stronger than the energy of 850 nm. What is the performance of the new IR LED? OSRAM has launched a 810 nm infrared LED for mobile device iris sensors. The SFH 4703AS, introduced this time, uses high-efficiency chips from nano-stack technology and is stacked on Oslon Lighting packages. At one ampere current, the transmitter produces one watt of optical power; a positive and negative 45 degree emission angle provides a wider illumination range, and at one ampere current, the radiant intensity is 630 milliwatts per square (mW/sr). The product measures 3.85 x 3.85 mm and the height of the lens is 2.29 mm. With the addition of this new product, OSRAM currently has three compatible infrared LEDs with different wavelengths. These products can be combined in a single lighting unit or used to change the spectral range of an existing system without the need to re-pin the pin.
