Title: Hiroaki Nagai: Innovator in Discharge Lamp Technology

Introduction

Hiroaki Nagai is a notable inventor based in Kitakyushu, Japan. He has made significant contributions to the field of discharge lamp technology, holding a total of 2 patents. His innovative approaches have led to advancements in the efficiency and functionality of discharge lamps.

Latest Patents

Hiroaki Nagai's latest patents include a discharge lamp, a discharge lamp sealing method, and a discharge lamp sealing device. In his sealing apparatus, luminescent substances are charged into an arc tube through an opening. An electrode member is then inserted into the arc tube through the same opening. The lower end of the arc tube is supported by a support jig, which is designed to hold a glass ring around the circumference of the opening. The arc tube is set in an air-tight condition by a feeding conduit and inserted into a heating unit. This heating unit fuses the glass ring using the heat from an infrared lamp, effectively sealing the opening. During this sealing process, one end of the arc tube is supported by the support jig, which is primarily made of a material with greater thermal conductivity than that of the arc tube, such as aluminum or copper. This design allows heat to be efficiently conducted from the arc tube to the support jig, preventing a temperature rise in the arc tube and ensuring that the luminescent substances do not vaporize and escape.
