THE SCIENCE BEHIND OUR LED TECHNOLOGY

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 a copper/ 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 thermal conductivity, power converting 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 wafers and then chips that were sold to LED assembly companies.

HEAT DISSIPATION MECHANISM (LASER TECHNOLOGY):

SST used MOCVD technology to fabricate laser wafers and chips in its early years. In 2011, SST developed a high-power outdoor laser light to aid in capturing images of the bottom of a passing high-speed train. This laser light utilized multiple high power laser modules with a quartz lens to create parallel light beams from the fixture. This laser light was completely sealed to be weatherproof and to survive the harsh vibrations of a high-speed train track.

SMART CONTROL TECHNOLOGY:

SST also specializes 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.

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.

In 2023, SST was awarded NASA SBIR Phase I project to develop Radiation Resistance Enhanced Class AB Amplifiers for Space Coronagraphic Instruments.
