Title: **The Innovative Contributions of Takeshi Fukuyo**

Introduction

Takeshi Fukuyo, based in Shizuoka, Japan, is a distinguished inventor renowned for his advancements in lighting technology. With an impressive portfolio of 31 patents, Fukuyo has significantly contributed to the field of discharge lamp devices, particularly focusing on mercury-free technologies that enhance efficiency and performance.

Latest Patents

Among his latest innovations, Fukuyo has developed an arc tube for discharge lamp devices, which features a mercury-free design. This arc tube includes a sealed glass chamber containing metallic halides for light emission, along with rare gas, achieved through a unique pinch-sealing technique. Notably, the electrode bars, positioned opposite each other within the chamber, have tips formed of single crystal material. This design allows for the crystal at the tips to grow despite the frequent ON/OFF cycling of the arc tube, ensuring that the electrode end face remains consistent in shape. This uniform consumption pattern prevents a decline in the luminescent spot during discharge.

Another significant invention is the mercury-free arc tube for a discharge lamp unit, which encapsulates a closed glass bulb filled with light-emitting substances such as NaI, ScI, along with buffer substances like InI and ZnI and xenon gas. The strategic composition of ScBr, ranging from approximately 5 wt% to 24 wt%, enhances the effectiveness of this innovative lamp design. Additionally, this arc tube may be complemented by a shroud glass tube that encloses the glass bulb and incorporates a pair of electrodes situated inside the bulb.
