Laser Lighting Thermal Management Patent Snapshot
This is a small, China-dominated field with 34 patent families in scope; Supervision Laser Tech (Suzhou) holds the lead position, and the competitive structure is fragmented below the top tier. Activity peaked around 2020 and has eased since, placing the field in a post-peak phase where strategic white space remains in active-cooling and positioning-integrated branches.
Supervision Laser Tech leads a fragmented, China-centric field
Supervision Laser Tech Suzhou Co Ltd holds the top position with 5 patent records, ahead of a cluster of filers each holding 2–3 patent records, including EINS TECH, the Xinyi Xiyi Advanced Materials Research Institute of Industrial Technology, Sichuan Changhong Electric, and Beijing Zhongxing Xunda Tech.
The top five filers account for 35% of the combined total among the ranked applicants visible in this query, indicating moderate concentration at the very top but a long tail of single-record contributors — roughly half the ranked applicants hold only one patent record each.

Supervision Laser Tech’s lead, built on F21V (lighting device components) filings, reflects a product-engineering orientation focused on heat-dissipation integration within the luminaire itself. No single player has yet established an insurmountable position, leaving the assignee snapshot genuinely open.
Filing counts for 2023–2025 are likely under-represented due to standard patent-publication lag of 18–24 months; the apparent recent decline should not be read as a definitive drop in inventive activity. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
Filing activity peaked in 2020; lighting-component IPC classes dominate the technology mix
The annual filing trend and IPC class breakdown together show a field that expanded quickly between 2018 and 2022 and is now consolidating, with thermal-management innovation concentrated in luminaire-level component engineering rather than standalone cooling-system design.
Annual filing trend
Filings rose from 2 in 2018 to a peak of 8 in 2020, held near that level in 2022, then contracted. Counts for 2023 onward reflect publication lag and should be treated as minimums rather than final totals.

F21V (lighting device components) is visible in, reflecting heat-sink and optic-integration patents filed at the fixture level. H01S (lasers and stimulated emission) and F25B/F25D (refrigeration and active cooling) together represent a smaller but technically distinct cluster, suggesting that active thermal-management approaches remain a minority route.

High power semiconductor laser lighting device
A high power semiconductor laser lighting device has a housing, a fan module arranged in an exhaust hole in the housing, a base connected to the bottom wall of the housing and disposed on a side of the fan module, and a semiconductor laser constant-temperature module. The base has a driving unit with at least one high power electronic component connected to… (excerpt from the patent abstract)

Ranked by total forward citations. Citation counts favour older and broadly cited patent families, and broad or adjacent patents may appear when they match the search scope. Treat this section as citation context, not as a curated list of the most topic-specific patents. Some patent titles may be shown in their original, non-English language where an accurate translation could not be guaranteed.
Assignee snapshot from the current evidence set
The applicants below are visible in this query result. Because the evidence set is relatively small, read this section as a directional snapshot rather than a full competitive ranking.
Supervision Laser Tech Suzhou Co Ltd
Holding 5 patent records — the highest count in the ranking — Supervision Laser Tech’s portfolio is concentrated in F21V 29 (lighting device thermal components), F21V 9 (optical components), and F21V 7 (reflectors), indicating a system-integration approach to thermal management within the luminaire enclosure. No momentum data for this applicant is available in the current evidence set, suggesting an established rather than accelerating filing pace.
patent records: 5EINS TECH
With 3 patent records, EINS TECH is technically differentiated from all other ranked applicants by virtue of its focus on H01S 5 (semiconductor laser emission), F25B 21 (thermoelectric refrigeration), and F25D 23 (cooling enclosures) — the only filer combining laser-source and active-cooling IPC classes. This positions EINS TECH as the primary incumbent in the active thermal-regulation sub-space. No prior-period filings are recorded in the momentum data, consistent with a focused recent entry.
patent records: 3Frequently asked questions
The corpus covers 34 patent families in scope globally. This is a small, specialist field relative to broader laser-lighting or general thermal-management domains.
Supervision Laser Tech Suzhou Co Ltd leads with 5 patent records, ahead of EINS TECH and the Xinyi Xiyi Advanced Materials Research Institute of Industrial Technology, each with 3.
China accounts for 36 patent-record filings, by far the visible jurisdiction. The United States follows with 5 and Taiwan with 1. Coverage in European, Japanese, and Korean patent offices is not represented in the current evidence.
Annual filing volume peaked around 2020 and has eased since, placing the field in a post-peak phase. Counts for 2023–2025 are subject to publication lag and should be treated as minimums; the full extent of the recent slowdown will only become clear as those filings publish.
The visible IPC class is F21V (lighting device components), reflecting passive heat-dissipation engineering integrated into the luminaire. Active-cooling approaches covered by F25B and F25D are present but account for a much smaller share of records, concentrated in EINS TECH’s portfolio.
The most-cited work covers integrated laser lighting and LiDAR systems (44 and 22 citations respectively) and a high-power semiconductor laser lighting device (26 citations). These citations suggest that sensing-integrated and high-power thermal-management designs are technically influential reference points for the field.
