SANANBIO Patent Publication Describes Lighting for Purple-Red Lettuce
A publicly available international patent publication lists Fujian SANANBIO Technology as the original applicant for a proposed indoor lighting environment for purple-red lettuce.
An international patent publication dated January 12, 2023, describes a proposed approach to managing the light environment for purple-red lettuce produced indoors. The published record identifies Fujian SANANBIO Technology Co., Ltd. as the original assignee and lists inventors associated with the application.
The technical description discusses the challenge of obtaining strong leaf coloration while maintaining acceptable productivity in controlled-environment cultivation. It specifies combinations of spectral regions and lighting conditions intended to address that challenge, with examples of LED spectral distributions.
The patent publication is a useful historical reference for the company's work on crop-specific plant lighting. However, publishing an application does not prove that a product was commercialized, that a patent remains in force, or that any claimed performance was independently confirmed. The public Google Patents record indicates a ceased status for this application, so the article should be treated as a research and intellectual-property history item rather than a current protected-product claim.
