The largest lighting factory in China is not necessarily the safest choice for a mine or tunnel. Production scale cannot compensate for the wrong optics, voltage, certification or product category.
A highway tunnel luminaire, a mine-approved explosion-proof roadway lamp and a waterproof LED strip solve different problems. Treating them as interchangeable is one of the fastest ways to create a failed specification.
This list therefore contains only 10 companies with identifiable mining or tunnel products, solutions or project evidence. It is shorter than many supplier lists because general lighting brands and unverified “professional manufacturers” were deliberately excluded.

How this list was verified
Each company had to meet at least one of these conditions:
- An official mine-lighting product or mining-industry solution;
- An official tunnel-light product category;
- Named tunnel project evidence on the company website;
- A dedicated underground-mining or tunnel LED strip product range.
Companies were removed when their official websites showed only general road lighting, smart-city content, decorative strips or factory-class explosion-proof products without direct mining or tunnel evidence.
1. Shanghai Sansi
Shanghai Sansi is one of the strongest Chinese choices for large road-tunnel lighting and intelligent transport projects.
Its public project evidence includes major infrastructure such as the Hong Kong–Zhuhai–Macao Bridge and the Shenzhen–Zhongshan Link. Sansi’s work extends beyond supplying fixtures: the company combines optical design, luminaires, sensing, dimming and control systems.
This makes Sansi particularly relevant to highway tunnels where entrance luminance, transition zones, visual adaptation and control strategy must be engineered as one system. It is not a specialist flexible mining-strip manufacturer.
Best for: Highway tunnels, immersed tunnels, entrance-zone lighting and intelligent controls.
Location: Shanghai, China
2. Ocean’s King Lighting
Ocean’s King is a professional industrial-lighting manufacturer with direct products and solutions for mining.
Its official catalogue includes mine explosion-proof LED roadway lights and mine explosion-proof LED support lights. The company also publishes a coal-industry lighting solution covering underground working areas and open-pit mines.
That direct mining evidence is important. It separates Ocean’s King from companies that merely sell generic high bays or explosion-proof fixtures and then describe them as suitable for every harsh environment.
Best for: Mine roadways, working faces, support lighting, portable lighting and mine maintenance.
Location: Shenzhen, China
3. Tormin
Tormin develops professional industrial and mining lighting in Zhejiang.
Its official product range includes fixed mine explosion-proof lighting and DGS-series mine explosion-proof LED roadway lamps. These are identifiable mining products rather than ordinary industrial fixtures with a mining keyword added to the description.
The exact safety-mark certificate, model number, mine type and installation conditions should still be checked before ordering. A product family name is useful evidence, but it does not replace model-level compliance verification.
Best for: Underground roadway lighting, fixed mine lighting and mine explosion-proof applications.
Location: Zhejiang, China
4. Xmart Lighting
Xmart Lighting manufactures configurable continuous lighting through production bases in China and Vietnam.
Its Tunnel & Mining LED Strip is available in 24V, 36V and 48V versions. Published features include IP67 protection, IK10 impact resistance, silicone extrusion and pre-terminated reels.
The choice of voltage matters more than many buyers expect. A short maintenance passage and a long conveyor route should not automatically use the same circuit. Higher low-voltage options can reduce current and voltage drop, but conductor size, power, feed spacing and site rules must be calculated together.
Xmart’s main strength is OEM flexibility. Reel length, wattage, colour temperature, connectors, packaging and private-label requirements can be adapted for distributors and contractors. Standard industrial versions should not be presented as coal-mine approved or explosion-proof unless the exact supplied model carries the required certification.
Best for: OEM programmes, non-classified underground routes, conveyors, utility tunnels and construction passages.
Location: China and Vietnam

5. NVC Lighting
NVC has a dedicated LED tunnel-lighting range rather than only a general infrastructure catalogue.
Its official products include the NTLED72X tunnel luminaire, products for metro-tunnel applications and tunnel emergency or guidance lighting. This gives NVC a clearer transport-lighting position than large brands whose websites contain no identifiable tunnel fixture.
NVC is most suitable for projects requiring conventional fixed luminaires, project support and integration across several transport-lighting functions. Buyers should request photometric files and confirm the exact model rather than relying on brand recognition.
Best for: Road tunnels, metro tunnels, transport facilities and project-based fixed lighting.
Location: China
6. Chainzone Technology
Chainzone combines tunnel lighting with intelligent transport products.
Its official tunnel range includes the LE Tunnel Light series with stated electrical, optical and environmental parameters. The company’s wider traffic-display and intelligent-transport capabilities may also be useful when lighting forms part of an integrated tunnel system.
Chainzone should be evaluated as a fixed road-tunnel luminaire supplier. It is not a continuous flexible-strip specialist or a substitute for mine-approved underground equipment.
Best for: Highway tunnels, underpasses, traffic infrastructure and intelligent transport integration.
Location: Foshan, China
7. HPWINNER
HPWINNER has direct tunnel-product and project evidence on its official website.
Its tunnel range includes TS21, TS2C and TS31A LED tunnel lights. The company also lists completed tunnel-lighting applications in Guangzhou, Hangzhou, Ji’an, Shenzhen and Zhoushan.
This combination of a dedicated product category and named project locations provides a stronger basis for inclusion than a generic statement that outdoor lights “can be used in tunnels.”
HPWINNER is relevant to high-output fixed lighting and module-based luminaire engineering. It does not compete directly with low-voltage mining strip or mine roadway lamps.
Best for: Road tunnels, project-specific optics and high-output fixed luminaires.
Location: Hangzhou, China
8. ZGSM Lighting
ZGSM is an export-focused manufacturer with a dedicated LED tunnel-light category and published tunnel application material.
Its official range includes modular tunnel luminaires, IP66 and IK10 options, adjustable brackets and products intended for roadway and railway underpasses. The company also publishes tunnel project case studies.
ZGSM is a practical candidate for importers and contractors comparing conventional tunnel fixtures, export documentation and OEM options. It should not be classified as a mining LED strip manufacturer.
Best for: Export tunnel projects, road infrastructure and OEM fixed luminaires.
Location: Hangzhou, China
9. DERUN LED
DERUN manufactures flexible LED strip and has a dedicated underground-mining lighting range.
Its official website presents continuous strip systems for underground mining, tunnels and construction lighting. Product examples include IP68 low-voltage strip and long-run driveless products intended for demanding continuous routes.
Buyers should verify the full installed system rather than only the extruded strip. Connectors, end caps, power feeds, maximum run length, repair sections and flame performance often determine whether the system succeeds underground.
Best for: Continuous underground routes, conveyors, construction tunnels and customized strip projects.
Location: Shenzhen, China
10. PILED
PILED markets a dedicated mine LED strip category with products for underground mine tunnels.
Its published range includes AC36V silicone strip, IP68 construction and products described for underground mining routes. This direct product evidence supports inclusion, although buyers should independently verify any explosion-protection claim against the exact certificate and delivered model.
PILED is most relevant to OEM buyers seeking a focused low-voltage strip supplier. It should not be compared directly with large road-tunnel engineering companies.
Best for: Mine LED strip, construction tunnels and project-specific low-voltage systems.
Location: Shenzhen, China
The counterintuitive rule: choose the product category before the supplier
Many sourcing projects begin with a list of factories. Mine and tunnel lighting should begin with the operating environment.
First define whether the site is:
- A highway or railway tunnel;
- A coal mine or non-coal mine;
- A classified explosive atmosphere or a non-classified service route;
- A permanent installation or temporary construction passage;
- Primary illumination, emergency lighting or directional guidance.
Only then should suppliers be compared. The strongest road-tunnel company may be wrong for a coal-mine roadway, while a durable continuous strip may be wrong for primary highway-tunnel illumination.
Seven technical factors to compare
1. Exact certification scope
MA or KA mine safety marks, factory explosion-proof certificates, CE, CB, UL, ATEX and IECEx are not interchangeable. Match the certificate to the exact product model and destination.
2. Complete-system ingress protection
IP67 or IP68 on the extrusion does not prove that connectors, end caps, cable entries and repaired joints remain sealed after installation.
3. Voltage drop
For continuous routes, calculate voltage drop using actual wattage, conductor size, run length and feed arrangement. Buyers can compare Xmart’s 24V, 36V and 48V options when preparing the circuit design.
4. Tunnel photometry
Highway tunnels require controlled luminance through entrance, transition, interior and exit zones. Wattage alone is not a tunnel-lighting design.
5. Impact and vibration
Check luminaire IK rating, mounting method, cable restraint and connector retention. Underground and construction routes are rarely gentle environments.
6. Replaceable section length
A local impact should not require replacing an entire long run. Confirm the shortest serviceable section and the tools needed for repair.
7. Emergency behaviour
Define what happens after power failure: maintained output, battery duration, evacuation guidance, central control and restart behaviour.
When continuous LED strip is the better choice
Continuous strip can reduce dark gaps along conveyors, walkways, cable galleries, utility tunnels and temporary construction passages. It can also make the direction of travel easier to understand.
However, it is not automatically suitable for a coal-mine explosive atmosphere, and it normally does not replace engineered highway-tunnel luminaires. Waterproofing and impact resistance are only part of the specification.
For a custom non-classified route, send Xmart a quick enquiry with the route length, voltage, target illuminance, ambient conditions, connector type, certification requirement and estimated quantity.
Final recommendation
Choose Shanghai Sansi for major intelligent road-tunnel projects. Ocean’s King and Tormin are stronger candidates when the requirement is explicitly mine-related. NVC, Chainzone, HPWINNER and ZGSM are better matched to fixed transport and tunnel luminaires.
For continuous industrial strip, compare Xmart, DERUN and PILED at system level. Xmart is particularly suitable for buyers who need configurable voltage, reel length, connectors and private-label production.
The right shortlist is not the one with the most famous names. It is the one in which every company can prove that its product category matches the actual site.
Frequently asked questions
Who is the best tunnel-light manufacturer in China?
There is no single best supplier for every tunnel. Shanghai Sansi is strong in large intelligent road-tunnel systems, while NVC, Chainzone, HPWINNER and ZGSM offer fixed tunnel luminaires for different project and export needs.
Which Chinese companies make mining LED strip?
Xmart, DERUN and PILED publish continuous strip products or solutions for mining, underground or tunnel routes. Certification and complete-system performance must be checked for the exact application.
Can an IP68 LED strip be used in a coal mine?
Not automatically. IP68 addresses water and dust ingress; it does not prove mine approval, explosion protection or flame performance.
What voltage is suitable for a long mining-light route?
It depends on power, conductor size, route length and feed spacing. A higher low-voltage system may reduce current and voltage drop, but the complete circuit must comply with site rules.
Can LED strip replace highway-tunnel luminaires?
Usually not for primary traffic illumination. Highway tunnels require engineered photometry and luminance control for different visual zones.
What should an RFQ include?
Include the site type, route drawing, destination country, voltage, run length, target illuminance, ambient conditions, certification, connector preference, quantity and schedule.
