Title: Tetsuya Kamada: A Pioneer in White Light Emitting Devices

Introduction

Tetsuya Kamada, an innovative inventor hailing from Hyogo, Japan, has made significant strides in the field of light-emitting technology. With a portfolio of three patents under his name, Kamada has pushed the boundaries of how light sources can be designed and utilized in various applications.

Latest Patents

One of Kamada's latest innovations is a white light emitting device. This device features first and second light-emitting units, each receiving different electrical currents. By applying the first current to the first light-emitting units and the second current to the second light-emitting units, Kamada's device achieves an average emission chromaticity that produces identical colors. However, when the same current is used for both sets of units, it results in non-identical colors, showcasing the device's versatility.

In addition to that, Kamada has patented a light source device and a light projecting device. This invention comprises a substrate with a matrix of light-emitting units. Notably, reflective resin is strategically placed within the substrate to enhance the light-emitting units’ performance. This design includes first and second light-emitting units positioned adjacent to one another, with a reflective portion that extends in a direction intersecting their alignment. The innovative structure enables better interaction between light-emitting units, thereby improving the overall efficiency of the light source.
