Microwave Plasma Lighting

Electricity consumption for lighting is said to be over 15% of the world’s total electricity, in which 5% of that contributes to worldwide greenhouse gas emissions. By 2030, a 50% rise in lighting demand is estimated due to the ever-increasing global population. Solid-State lighting also commonly known as plasma lighting has the potential to offer power efficiencies and visual acuity incomparable to those of conventional lighting sources.

Plasma lighting also commonly referred to as electrodeless microwave lights (EMLs) is seemingly integrating into mainstream markets, due to its excellent color rendering index and longer lifetime. The enhanced color rendering and powerful visual acuity produced by EML’s give them a competitive edge to outdoor environments using natural sunlight.

By utilizing RFHIC’s advanced GaN solid-state semiconductor technology, it allows RF energy to excite plasma in a light bulb to generate efficient and near to pure sunlight for a variety of applications from agricultural to medical.

Plasma Lighting Applications

Streetlights

RFHIC is bringing RF energy to light, by instilling our highly efficient GaN on SiC transistors into our microwave electrodeless lights (MELs). As a result, this allows RF lighting to have excellent lumen/watt beating conventional sources, while also decreasing OPEX costs.

Wide Coverage Lighting

RFHIC’s high lumen density of MELs makes them an ideal candidate for replacing LEDs and high-pressure sodium (HPS) lights for wide coverage lighting environments like warehouses, stadiums, airports, parking lots, and more. In all wide coverage lighting applications, GaN solid-state plasma lights deliver even light distribution and high levels of visual acuity ensuring the most optimal source of light for all wide area environments.

Agricultural Grow Lights

Plasma grows lights provide a unique ability to emit a continuous, full spectrum of light almost exactly to natural sunlight, which allows horticultural applications to be more reliable and controllable.

Plasma grows lights also enable the capability to tune the lighting to different frequencies and light spectrums, resulting in healthier and more nutrient dense plants, fruits, and vegetables.

Microwave Sterilization Lights

Nowadays putrefaction (the process of decay) of industrial products such as foods, beverages, and cosmetics by microorganisms is one of the most crucial problems. To overcome such challenges, various sterilization processes have been carried out in industrial fields.

  • Heat Sterilization
  • UV Light Sterilization
  • Ozone Gas Sterilization
  • UV Microwave Assisted Light Sterilization

Particularly the food industry, heat sterilization is often used exposing foods and beverages to high temperatures using steam or conventional heat for a period. Since conventional methods tends to only sterilize the surface of the product, it requires a longer processing period – which therefore deteriorates the overall food quality.

According to research studies combining both ultraviolet (UV) and microwave lights provided the most optimal sterilization results compared to UV or Microwave light alone.

By combining both UV and Microwave lights the generation of active oxygen species is much greater resulting in a high efficiency in decomposing chemical substances.

Also, with the current pandemic, UV + Microwave light sterilization methods are becoming popular methods in preventing the spread of viruses for wide coverage areas. Due to its high efficiency and longer lifetime, the combination of UV and Microwave plasma lights were found to be convenient and economical.

RFHIC’s Microwave Electrodeless Lighting

RFHIC’s MEL-350 is a complete plasma light system built using RFHIC’s cutting edge gallium-nitride (GaN) on SiC HEMT technology. The system generates a color rendering index of 97, a spectrum almost equivalent to the sun.

The MEL-350 system is equipped with a halogen compound bulb and RFHIC’s GaN solid state power amplifier to generate the microwave source. The compact size system is cooled using an external heat-sink and airflow.

The MEL-350 provides an excellent optical spectrum and can be used for various agricultural applications (vertical farming, indoor grow lights), streetlights, wide coverage lighting, and more.
