SST Technologies

The Science behind the Solutions

How the SST Technology is different:

SST LED systems utilize vertical integration in our manufacturing process and directly control all aspects of its product design and production from the LED chip level to the final solution.
Patented AS-LED Technology:

SST’s AS-LED technology places LED chips directly onto an aluminum heat sink and uses a single glass or quartz lens to maximize the final light output. The AS-LED technology eliminates the Metal Core Printed Circuit Board (MC-PCB) and secondary lenses used in conventional LED systems. This design leads to significantly less heat generation, unmatched heat dissipation, lighting efficiency, and operating lifetime compared to traditional LEDs. SST has been utilizing the AS-LED technology since 2005 when it was first incorporated in an adhesive curing application. Other UV LED manufacturers are still placing pre-packaged LEDs on the Metal Core Printed Circuit Board (MC-PCB) and incorporate a secondary lens.

MOCVD Technology:

In its early years, SST used Metal Organic Chemical Vapor Deposition (MOCVD) technology to fabricate LED chips that were sold to assembly companies.  In 2000, SST won the Competitive Award from the Kansas Enterprises Technology Corporation to develop Aluminum-Indium-Gallium-Phosphide (AlInGaP) High Brightness LED (HB-LED) products using MOCVD.

Heat Dissipation Mechanism (Laser Technology):

SST used MOCVD technology to fabricate laser chips in its early years. In 2011, SST developed a high power outdoor scanning light to aid in capturing images of the bottom of a passing high-speed train. This scanning light utilized a laser diode with a quartz lens to create parallel light beams from the fixture. This scanning light was completely sealed to be weather proof and to survive the harsh vibrations of a high-speed train track. SST designed the Heat Dissipation Mechanism for the chip so that the 300mm 80W laser does not need a fan to assist in cooling.

Smart Control Technology:

SST also specialize in smart controls that can be programmed to run from PLC sensors or from a pre-scheduled pattern. A smart control system maximizes efficiency by automatically controlling and adjusting lights based on the surrounding environment or position of the user. SST’s LED lamps can be upgraded to be smart controlled without changing the fixtures. All of SST’s LED lamps can be incorporated into a existing smart control system.

Patented Integrated Circuit Technology:

In 2018, SST also received a patent for an Isolated Bidirectional High-Voltage Analog Switch. This technology is the key component in designing Switching Electronics for Space-Based Telescopes with Advanced Adaptive Optic (AO) Systems. The 1-1024 High voltage (HV) 32X32 switch array delivers and holds voltage signals for the PMN Deformable Mirror (DM). Every HV switch in the array features low leakage and is feed-through free.

NASA SBIR Projects

In 2015, SST was awarded NASA SBIR Phase I project to develop switch electronic arrays to drive DM (Deformable Mirrors) for space telescopes. As a result of this successful project, SST was awarded NASA SBIR Phase II to continue the project for two more years. The resulting 1-1024 High voltage (HV) 32X32 switch array can deliver and hold voltage signals for the PMN Deformable Mirror (DM). Each of the HV switch in the array features low leakage and is feed-through free.

In 2019, SST was awarded NASA SBIR Phase I project to develop Linear Regulators to drive DM for space-based telescopes. As a result of this successful project, SST was again awarded NASA SBIR Phase II award to continue the project for two more years.
