Infrared applications\u00a0ranging from night\u00a0vision security cameras to photothermal medical devices\u00a0demand extreme thermal stability, compact optical geometry, and exceptional beam uniformity.<\/p>\n<p>For years, optical hardware engineers relied on arrays of discrete SMD IR LEDs to deliver high\u00a0power illumination. However, SMD arrays often present severe layout bottlenecks: high thermal resistance, uneven light intensity (&#8220;hotspots&#8221;), and bulky physical footprints.<\/p>\n<p>The IHY299 Series is IHY Lighting&#8217;s engineering response to these optical limitations. Designed as an integrated 20W high\u00a0power COB, the IHY299 demonstrates how customized COB packaging elevates system performance for OEMs and ODMs worldwide.<\/p>\n<p><span style=\"font-size: 14pt;\"><strong>1. Optical Metrics: Dominant Wavelength vs. Peak Wavelength<\/strong><\/span><\/p>\n<p>When specifying infrared LEDs, engineers often encounter ambiguity between Dominant Wavelength (\u03bbd) and Peak Wavelength (\u03bbp). Understanding this distinction is critical for precise optical matching.<\/p>\n<ul>\n<li><strong>Peak Wavelength (\u03bbp): <\/strong>The exact physical point in the spectral distribution curve where the light output reaches its absolute maximum radiant power.<\/li>\n<li><strong>Dominant Wavelength (\u03bbd): <\/strong>The single calculated wavelength that represents the perceived spectral center of the light source, taking into account the broader spectral distribution curve.<\/li>\n<\/ul>\n<p>For the IHY299 series, all optical metrics are defined by Dominant Wavelength, ensuring strict consistency in camera sensor responsiveness and biological skin penetration across production batches.<\/p>\n<p><span style=\"font-size: 14pt;\"><strong>2.

Frequently Asked Questions (RFQ)<\/strong><\/span><\/p>\n<p>Q: Can this product pass international compliance and safety certifications?<\/p>\n<p>A: Yes. The IHY299 series is designed to comply with CE, RoHS, EN 62471,and FDA standards. If your project requires specific certifications (such as IEC\u00a0or REACH compliance), we can adjust component selection and testing procedures during prototyping to meet your target market requirements.<\/p>\n<p>Q: What\u2019s the typical custom sampling turnaround time?<\/p>\n<p>A: For standard single\u00a0function light sources using existing substrates, sample production takes within 1 week. For complex, highly customized requests (involving custom FPC outlines, non\u00a0standard voltages, or multi\u00a0spectrum layouts), lead times are evaluated directly based on project requirements.<\/p>\n<p>Q: Do you provide engineering drawings before prototyping?<\/p>\n<p>A: Absolutely. We provide detailed CAD engineering drawings for your confirmation before manufacturing any physical prototypes. This eliminates design misunderstandings, prevents costly sample iterations, and helps accelerate your time\u00a0to\u00a0market.<\/p>\n<p>&nbsp;<\/p>\n<table>\n<tbody>\n<tr>\n<td style=\"background-color: #083769; width: 828px;\" width=\"828\"><span style=\"color: #ffffff; font-size: 18pt;\"><strong>Conclusion: Partnering with IHY Lighting<\/strong><\/span><\/p>\n<p><span style=\"color: #ffffff;\">From single-wavelength IR illuminators to multi-spectral custom COB modules, IHY Lighting delivers end\u00a0to\u00a0end engineering support\u00a0from initial optical simulation to mass production.
