Swirled 1000-1750nm LED
Choose a custom 1000–2000 nm SWIR LED package by package type, viewing angle, MOQ, optical power, and thermal performance.
Custom SWIR LED Packages: Package Type, Viewing Angle, Low MOQ and High-Power Thermal Design
A suitable custom SWIR LED package must balance four key factors: package structure, viewing angle, minimum order quantity and thermal performance.
Shenzhen Yingfeng Opto-Electronic Co., Ltd. supplies custom SWIR LED packages covering 1000–2000 nm, with an optional wavelength tolerance of ±20 nm and selectable viewing angles of 20°, 30°, 60° and 120°. Low-MOQ support is available for prototype development, sample evaluation and specialized applications.
1. How Do You Select a SWIR LED Package?
The package protects the SWIR LED chip, provides electrical connections, controls light distribution and transfers heat away from the junction.
The correct package depends on:
- Available installation space
- PCB layout and mounting method
- Required radiant power
- Working current
- Optical-axis position
- Lens or window requirements
- Operating temperature
- Continuous or pulsed operation
- Required heat-dissipation capability
A compact package may be suitable for space-limited sensors. High-power applications usually require a package with a better thermal path, a suitable PCB and additional heat dissipation.
When requesting customization, provide the package dimensions, PCB footprint, installation height and mechanical drawing whenever possible.
2. Which SWIR LED Viewing Angle Should You Choose?
The viewing angle determines how optical energy is distributed across the target.
20°: Concentrated SWIR Output
A 20° angle produces a narrow beam and concentrates more optical energy on a smaller area. It is suitable for:
- Longer working distances
- Small-target illumination
- Focused sensor testing
- Applications requiring higher irradiance
30°: Focused but Flexible
A 30° viewing angle provides a balance between beam concentration and coverage. Typical applications include:
- Machine vision
- Infrared camera testing
- Sensor calibration
- Medium-distance illumination
60°: Balanced Coverage
A 60° angle illuminates a larger area while maintaining moderate beam concentration. It is commonly selected for:
- Industrial inspection
- Material recognition
- Imaging systems
- Medium-area illumination
120°: Wide-Area Illumination
A 120° viewing angle distributes SWIR energy across a broad area. It is appropriate for:
- Short working distances
- Large-area illumination
- Multi-sensor systems
- Applications requiring wider coverage
The correct angle should be selected according to the working distance, target size and required irradiance—not from viewing angle alone.
3. Why Is Low MOQ Important for Custom SWIR LEDs?
Many SWIR applications begin with prototypes, laboratory tests or limited-volume equipment. A large minimum order quantity can increase development cost before the design has been validated.
Low-MOQ customization helps customers:
- Evaluate different SWIR wavelengths
- Compare several viewing angles
- Build engineering prototypes
- Test optical power and thermal performance
- Develop specialized instruments
- Reduce initial inventory risk
- Move from sampling to production more efficiently
Yingfeng supports low-MOQ requirements for suitable custom SWIR LED projects. The applicable MOQ depends on the wavelength, package, chip availability and customization level.
For early-stage development, customers can begin with samples or a small pilot order before confirming the final production configuration.
4. What Is a High-Power Thermal SWIR LED Package?
A high-power thermal package is designed to transfer heat efficiently from the LED chip to the PCB and heat sink.
Heat management is critical because excessive junction temperature may lead to:
- Reduced radiant power
- Wavelength shift
- Unstable optical output
- Lower measurement repeatability
- Shorter LED operating life
A high-power SWIR LED package may require:
- Low-thermal-resistance package materials
- An optimized internal heat-transfer path
- Metal-core or thermally enhanced PCB
- Suitable thermal-interface materials
- An external heat sink
- Controlled drive current
- Temperature monitoring or compensation
High-power capability should therefore be evaluated as a complete thermal system. Package design alone cannot compensate for an undersized PCB or insufficient heat sinking.
5. Continuous or Pulsed High-Power Operation?
The operating mode has a direct effect on thermal design.
Continuous operation provides steady SWIR illumination but generates sustained heat. It normally requires more effective thermal management.
Pulsed operation may allow higher peak output for short periods. However, the pulse current, pulse width, duty cycle and repetition frequency must remain within the approved operating limits.
To recommend the right thermal package, customers should provide:
- Continuous or pulse current
- Pulse width and duty cycle
- Operating frequency
- Ambient temperature
- Available PCB area
- Heat-sink conditions
- Required radiant power or target irradiance
