About YSM

Corporate Philosophy
– Management philosophy –

“YSM will continue to illuminate the future of the people whose lives we touch, while giving tangible shape to those things they live with and enjoy every day.”

We convert people’s ideas and elements of their imagination, not yet expressed as drawings, into pleasing shapes. Conceiving of new things and manufacturing them are just some of the steps in our creative process. We invest our products with such intangibles as empathy and excitement. We think this makes us a company worthy of being chosen again and again by customers and cooperating companies alike. We hope to light the way to the future in our quest to illuminate the world.

Custom Lighting

We can create lighting from an idea a customer has originated, that has not yet been expressed as drawings.
Our experienced staff will understand your ideas, help you with the design and make the necessary drawings.
We use our 20 years of know-how and our own machines to deliver finished products to you that started with simple statements of your basic product needs.
Over the past 20 years, we have delivered innovative products to major construction and railway companies.

Design Intelligence Award 2018

China is focusing special attention on the refinement of its design policy. This is China’s first international design award, which was established in 2016 by the DIA Committee of the China Academy of Fine Arts and sponsored by the Zhejiang Provincial Government. In order to establish its place among the world’s prestigious design awards, they have solicited sources of recommendations and identified judges in many countries, in collaboration with major design organizations around the world. Only the works recommended through their network will be accepted for evaluation and possible awards.


This is a world-wide design award started in 2003 by the Hong Kong Design Center, intended to position Hong Kong as an Asian design hub.
