Latest Patents

Among his latest patents, Chang has developed two notable inventions:

1. **Plasma lamp using a shaped waveguide body** - This invention features an electrodeless plasma lamp that incorporates a shaped dielectric waveguide body. The design includes a relatively thin region housing a bulb and a thicker region that accommodates microwave probes, which provide power to the waveguide body. The unique shape of the body intensifies the electric field near the bulb, allowing for operation at lower frequencies compared to traditional solid cylindrical or rectangular waveguides with the same volume and dielectric constant.

2. **Plasma lamp with dielectric waveguide integrated with transparent bulb** - This patent outlines a dielectric waveguide integrated plasma lamp that utilizes a body made of dielectric materials with a dielectric constant greater than approximately 2. The structure is designed to resonate in specific modes when microwave energy is applied. The transparent dielectric bulb within the lamp chamber contains a fill that creates a light-emitting plasma upon receiving energy. Additionally, the invention incorporates multi-layer coatings to recycle radiative energy lost from the plasma, enhancing the overall efficiency of the lamp.
