As electronic products evolve technologically and the push for miniaturization continues, space constraints for electronics remain a significant concern for design engineers.

Our Multi-chip & Multi-Wavelength Emitters have several LED chips combined in the same package to reduce overall component size. LEDs with different wavelengths can be placed in the package for applications such as colorimetry, spectrometry, medical diagnostics (oximetry, co-oximetry, photoplethysmography (PPG), optical coherence tomography (OCT), urinalysis, functional near infrared spectroscopy (fNIRS)),  fluorescence, and currency validation.  Multichip emitters are also used for high-reliability indicators, switch backlighting, and panel illumination.

The Marktech multichip LED series is available in various colors with polarized and non-polarized configurations for AC or DC operation. These low-profile emitters contain multiple, evenly spaced chips, combining for a consistent, wide-illuminated light pattern while consuming little power.

Several LED die or chips with the same wavelength can be packaged together for higher power output applications. Multiple LED chip products come in various package types including TO-18, PLCC, TO-5 and surface mount. These devices hold anywhere from 2 to 7 die and are available in our selected standard chips in UV through SWIR Short Wave Infrared ranges. The LEDs can be modified to the customer’s specifications, which includes power and wavelength sorting. InGaAs and silicon photodiodes can also be added into the package to provide both a light source and detection, which is especially useful for spectroscopy and biomarker sensing applications.

The Marktech hermetically sealed metal can multichip LED series offers high-output, low-profile emitters that contain multiple, evenly spaced chips, ideal for applications requiring same emission sources in a small, densely packaged area.

In applications with more than seven LEDs needing to be densely packed, Marktech has chip-on-board (COB) solutions where multiple LED die are directly placed into a small amount of space on a printed circuit board (PCB). COB offers many advantages compared to standard packaging. LEDs and electronic component are heat sensitive, so metal-cored boards are utilized where dense packing raises concerns of overheating devices.

While widely used in LED illumination applications, COB technology can significantly enhance emission and detection functions in sensing applications. Detectors can be soldered directly onto a printed circuit board with or without LED emitters. Packing more light emission or light detection chips into an area can enhance circuit and design performance in many applications.

Marktech’s Multi-chip & Multi-Wavelength Emitters, LED + Detectors, and COB products provide design engineers with several options to meet their space limitations and development needs.
