Company History

SAN-EI Electric Co., Ltd. was founded in Osaka, Japan.
The company successfully developed the world’s first horizontal short-arc xenon lamp system and commercialized xenon light sources for motion picture projection and laboratory applications.
At the same time, SAN-EI began manufacturing halogen stage lighting equipment and obtained multiple patents related to lighting technologies.

Sales of xenon and halogen light source systems expanded through distribution partnerships, establishing SAN-EI in professional lighting markets.

SAN-EI’s projection and lighting systems contributed to the success of Expo ’70 in Osaka.
Following the event, SAN-EI began exporting light sources for film projection, industrial use, and broadcasting applications.

Standardized xenon lamp housings for motion picture projection were developed and mass production began.

SAN-EI expanded into industrial light and heat technologies, developing infrared heating systems and high-intensity xenon light sources used for high-speed camera illumination and industrial applications.

During the 1980s and 1990s, SAN-EI expanded its expertise into optoelectronics and fiber-optic illumination systems.

The company developed xenon and halogen light sources for fiber-optic light guides, UV irradiation systems, and optical inspection equipment used in scientific research, industrial measurement, and imaging systems.

High-intensity xenon fiber-optic light sources (Super Bright Series) and advanced UV fiber illumination systems with feedback control were introduced and widely adopted in microscopy, inspection, and optical measurement fields.

These technologies established SAN-EI as a specialized manufacturer of high-intensity precision light sources.

SAN-EI began developing high-uniformity parallel UV exposure systems for industrial and research applications.

Development of a xenon solar simulator (JIS Class A), marking SAN-EI’s entry into solar simulation technology.

Development of a high spectral fidelity dual-lamp solar simulator with a 220 mm irradiation area for photovoltaic research.

Development of a compact high spectral fidelity solar simulator with a 50 mm irradiation area, delivered to leading research institutions.

Development of a compact high spectral fidelity solar simulator with a 50 mm irradiation area, delivered to leading research institutions.

Development of a large-area high-uniformity exposure system with a 520 mm irradiation area.

Development of a 600 W LED pin-spot lighting system, expanding SAN-EI’s technology into high-power LED lighting.

Development of UV sterilization equipment for infection control applications.


Today, SAN-EI continues to develop high-precision light source technologies, including advanced solar simulators used in photovoltaic research, materials science, and optical engineering.
