Edison Opto RNBE27D480800001 High-Power IR Emitter Combines an 80° Beam with 1.5W Radiant Power for Surveillance and Smart Sensing
As surveillance cameras, night-vision systems, facial-recognition devices, and distance-sensing products become smaller and more capable, their infrared light sources must provide sufficient optical output while meeting requirements for beam coverage, package size, thermal management, and system reliability.
The Edison Opto RNBE27D480800001 is an EDILON 3838 high-power infrared emitter developed for 850nm-class applications. The official product page specifies an 855nm peak wavelength, an 80° viewing angle, 950mW/sr radiant intensity, and 1,500mW radiant power for surveillance and intelligent-vision applications.
80° Beam Supports Broader Infrared Illumination
The RNBE27D480800001 provides an 80° viewing angle, allowing the emitter to illuminate a relatively broad field for surveillance cameras, access-control systems, and intelligent sensing equipment.
Compared with a narrow-beam source, a wider emission pattern can reduce excessive concentration at the center of the image and provide more useful coverage toward the edges of the field. Final illumination uniformity will still depend on the installation distance, camera field of view, enclosure, optical structure, and arrangement of multiple emitters.
Potential applications include:
● Indoor and outdoor surveillance cameras
● Smart locks and access-control systems
● Facial and object-recognition devices
● Gesture and motion sensing
● Distance and proximity detection
● Smart-home and smart-building equipment
● Industrial vision and nighttime inspection
855nm Peak Wavelength for Active Infrared Vision
The RNBE27D480800001 belongs to an 850nm application family, with the official product page specifying a peak wavelength of 855nm. It can be combined with CMOS image sensors, receiving devices, and optical filters that provide suitable response around this wavelength.
IR system performance depends on the complete optical chain rather than the emitter alone. Designers should evaluate:
● Image-sensor spectral response
● IR-cut filter or filter-switching architecture
● Lens transmission around 855nm
● Ambient-light interference
● Target reflectivity
● Required sensing distance
● Receiver field of view
● Camera exposure and gain settings
1,500mW Radiant Power and 950mW/sr Radiant Intensity
The official product page specifies 1,500mW radiant power, 950mW/sr radiant intensity, a 1,000mA operating current, and a 2.9V forward voltage.
Radiant power represents the total infrared optical output of the emitter, while radiant intensity describes the energy delivered in a particular direction. Both parameters must be evaluated together with the viewing angle and full radiation pattern.
The effective illumination or sensing distance of the final system will also depend on:
● LED-driver current accuracy
● Continuous or pulsed operation
● Number and arrangement of IR emitters
● Camera exposure time and gain
● Receiver sensitivity and lens aperture
● Target reflectivity
● Ambient-light conditions
● Module temperature and thermal performance
Compact EMC 3838 Package Saves Module Space
The RNBE27D480800001 measures 3.85mm × 3.85mm × 2.29mm, providing high-power infrared output in a compact form factor.
The small 3838 footprint is suitable for compact camera boards, smart locks, sensing modules, and embedded vision systems. Depending on the required field of view and illumination distance, engineers can use a single emitter or create a multi-emitter array.
Because the device combines high optical output with a compact package, thermal design remains essential. Recommended considerations include:
● Adequate solder-pad and copper area
● Thermal vias and internal copper planes
● A low-thermal-resistance PCB and enclosure path
● Separation from other heat-generating components
● A low-impedance path between the driver and emitter
● Worst-case temperature-rise verification
● Long-term optical-output stability
Driver Design Must Balance Current, Thermal Load, and Protection
With an operating current of 1,000mA listed on the official product page, the RNBE27D480800001 should be driven using a suitable constant-current LED-driver architecture.
Driver design should address:
● Input-voltage and LED forward-voltage margin
● Constant-current accuracy
● Startup and shutdown transients
● PWM or pulse-control requirements
● Maximum duty cycle
● Overcurrent, overvoltage, and thermal protection
● PCB power integrity
● Current sharing in multi-emitter configurations
For pulsed illumination synchronized with a camera shutter or sensing cycle, the peak current, pulse width, duty cycle, and thermal limits must be verified in the official datasheet rather than estimated from the continuous operating-current value.
