In thermal power plants and industrial environments, lighting is very important, especially in areas where there is a need for a high level of visibility for inspection, maintenance and emergencies.
In locations that rely completely on lights powered by an AC power supply, however, lighting availability is a concern when the regular AC power supply is unavailable.
That’s where 220V DC LED lighting can be an effective solution. Battery-backed DC systems are utilised in many power stations to provide critical protection and control functions when AC supplies are interrupted. Lighting products compatible with the plant’s DC supply can also be considered for selected applications where continued illumination is required.
Pyrotech has been in the industrial lighting field since 1976 and can provide DC lighting system for thermal power plants, steel plants, cement plants and other industrial facilities.
Why Is 220V DC Important?
Battery-backed DC systems are commonly used in Thermal power plant for circuit-breaker tripping and closing, protection relays, switchgear controls, alarming and other critical loads. Such a system is intended to provide a source of critical direct current (DC) power in the event of a loss of normal alternating current (AC) power.
If the lighting fixture is designed to be powered from a 220V DC source that has the correct compatibility, it can be used in an appropriate DC-powered lighting system.
This can be used to supplement lighting service during selected AC interruptions where the capacity of the DC source and design of the lighting circuit allow.
How Does 220V DC LED Lighting Work?
A 220V DC LED lighting system is a lighting system powered by a driver or internal power-conversion circuit that is designed to accept a compatible DC input. The driver controls the electrical power provided to the LEDs to give the LEDs a consistent level of lighting under the conditions they are required to operate.
The main factor to take into account is compatibility. We cannot guarantee that a conventional AC-only LED driver will operate on a 220V DC power supply. The driver chosen or the entire lighting fixture must be rated for the appropriate DC input.
Key Benefits of 220V DC LED Lighting
Compatibility with DC Power Systems: When switched to a well-designed battery-backed DC power source, compatible LED lights can power on when normal AC power fails. Actual operating time will vary according to battery size, load connected, battery condition and priority of lighting loads.
Most of the traditional lighting technologies are not as efficient in converting electrical energy into light as LED technology. The correct LED fixture can reduce electricity consumption whilst ensuring adequate levels of light for the application.
The number of lamp changes required is reduced compared to traditional lighting solutions when using Industrial LED lights. The maintenance requirement will vary according to the quality of the product, operating temperature, electrical conditions, exposure to dust and installation.
How Can 220V DC LED Lighting Help Reduce Costs?
With a proper LED light fixture, you can save power compared to the use of a conventional light source. Thus, total savings will vary as a function of the technology currently in place, the efficiency of the LED lights, the hours used and the required lumens.
If such an appropriate DC distribution system is already available, an appropriate lighting product can be integrated into the existing system. Before estimating savings, it is important to determine whether new circuits, protection devices, cabling and installation may be necessary.
The total cost of ownership includes all the electricity that is used, maintenance man-hours, replacement parts, downtime and the electrical infrastructure supporting these.
Recommendation: Make a cost-saving comparison of the proposed LED solution to the existing lighting system. Don't only think of the cost for the fixture, but also the power consumption, maintenance, installation, battery size and the expected battery life.
Technical Details to Consider
The following parameters should be reviewed when selecting 220V DC LED lighting for industrial use.
|
Parameter |
Selection consideration |
|
Input voltage |
Confirm compatibility with the actual DC bus voltage & its operating range |
|
Driver type |
Use a driver specifically designed & rated for DC input |
|
Power consumption |
Select the wattage according to the illumination requirement |
|

Review luminous efficacy, lumen output, & colour rendering |
|
Protection rating |
Select an appropriate IP rating for dust, moisture, & environmental exposure. |
|
Electrical protection |
Verify overvoltage, overcurrent, short-circuit, & surge protection as applicable |
|
Service life |
Review for manufacturer’s declared life & supporting test data |
The exact technical specifications vary by product model. Consult the relevant Pyrotech datasheet before finalising a selection.
Application Areas of 220V DC LED Lighting
Thermal Power Plants
In appropriate locations where an appropriate DC supply is available, power plants can employ LED lights that are compatible with DC power, provided they need to maintain continuity of illumination. Applications can include areas of maintenance, areas of inspection and designated areas of operation.
Cement Plants
Cement plants consist of Kilns, Mills, Conveyors, Equipment rooms, Maintenance areas, etc. The lighting product should be determined based on the conditions of dust exposure, temperature, mounting height, power supply, etc.
Oil and Gas Facilities
Special industrial or hazardous area lighting may be necessary for oil and gas installations. If there is the possibility of flammable gases or vapours, the fixture shall be certified for the classification of the area and the gas group.
Chemical Plants
Chemical processing facilities could need appropriate electrical and environmental protection lighting. Product selection should include consideration for corrosive conditions, moisture, temperature and any hazardous area classification.
Certifications and Compliance
Appropriate product certifications, electrical safety considerations, protection ratings and project-specific approvals should be taken into account when selecting industrial lighting.
The LM-79 test reports are for applicable LED products covering a Photometric and Electrical performance test.
LED package, array or module lumen-maintenance data provided in LM-80 test reports. Approvals such as EIL or other approvals, for specific models and configurations of the product. Pyrotech Technologies provides industrial LED lighting solutions for demanding applications.

Application-Based Product Selection
Lighting requirements differ across plant areas. Input voltage, wattage, mounting arrangement, environmental protection, and required illumination should all be considered when selecting a product.
1. Can a 220V DC LED be used if there's no AC power?
Yes, as long as it can be supplied by an appropriate DC power source. Run time is determined by the battery capacity, load and system design.
2. Will a standard AC LED driver work on 220V DC?
Not necessarily. Only use a driver or fixture that the manufacturer rates for the DC input.
3. In which applications is the use of 220V DC LED lighting allowed?
Where supplies and environment are adequate for the product, selected areas of power, steel, cement, oil and gas and in chemical plants, and in industrial maintenance areas.
4. If a light has a 220V DC rating, does this mean it is safe for use in a hazardous area?
No. A DC rating is only for electrical compatibility. A fixture with the correct EP rating is needed for a hazardous area.
5. Does Pyrotech have 220V DC lighting products?
Yes. Please refer to the product datasheet for information regarding models, specifications and suitability.
