Factory lighting design is typically disregarded in industrial operations, despite its importance to energy efficiency, worker safety, and overall productivity. Poor lighting not only reduces vision but also increases energy expenditures, causes frequent maintenance concerns, and poses safety risks. However, businesses may boost their earnings, decrease downtime, and create a safer working environment by investing in a well-designed lighting system, especially LED technology.
In this post, we’ll walk you through the major aspects of lighting design, from determining the necessary lux levels for different locations to selecting the correct fixtures and systems. What’s the goal? To assist you in improving your industrial lighting in a way that increases both productivity and profitability.
Why LED Lighting is the Best Choice for Factories
LED technology has revolutionized energy-efficient factory lighting. LEDs directly reduce costs because they use up to 75% less energy than conventional lighting systems like metal halide or fluorescent bulbs. They not only survive longer—up to 50,000 hours—but also require less maintenance, which lowers long-term operational costs.
Key Benefits of LED Lighting:
- Energy Efficiency: LEDs use substantially less power, resulting in cheaper energy bills and a decreased load on the grid.
- Long Lifespan: Because LEDs last up to 50,000 hours, they need to be replaced less frequently, which reduces maintenance costs.
- High Quality of Light: LEDs provide bright, homogeneous lighting that improves visibility, allowing workers to execute jobs more effectively.
- Low Heat Emission: Compared to conventional lighting, LEDs produce a lot less heat, which enhances factory climate control and reduces air conditioning costs.
LED lighting is a great option for every sector because of these advantages, which not only enhance the working environment but also yield a high return on investment (ROI).
Lighting Standards: What You Need to Know
Understanding the rules and guidelines governing industrial lighting is essential to creating a lighting environment that works. Appropriate lighting levels can boost output, lower mistakes, and protect employees. For instance, areas requiring inspections or precise labor will need more light than typical storage spaces.
Common Lighting Requirements:
- Production Lines: For general visibility, at least 300 lux is required, with 500 lux recommended for best results.
- Storage Areas: Lighting levels of 150-300 lux provide a safe, evenly lighted environment for workers to move around in.
- Precision Work Areas: Lighting settings in areas requiring fine precision, such as quality control, should be between 600 and 1000 lux to avoid errors.
- Warehouse Zones: These rooms normally require 150-300 lux to provide acceptable visibility without consuming excessive energy.
- Inspection Zones: In areas such as quality control, lighting levels of 600-900 lux are required to ensure complete inspections and reduce eye strain.
Meeting these standards is critical not only for compliance with requirements such as OSHA and ANSI/IES, but also for sustaining high levels of productivity and safety.
Lighting Design Considerations: More Than Just Brightness
Making your facility sufficiently bright is only one aspect of lighting design. When choosing and arranging fixtures, there are several factors to take into account in order to create a workstation that is secure, effective, and productive. Important factors to take into account are glare reduction, lighting homogeneity, and the climate in your facility.
Uniformity: Achieving Consistent Lighting
Shadows, glare, and areas of overexposure brought on by uneven lighting can lower worker productivity and raise the possibility of accidents. Light distribution across the factory floor is ensured by a well-designed lighting system, which is particularly important in places where accuracy is essential, such as production lines or inspection zones.
A uniformity ratio of 0.7 is good for general factory environments. A ratio of 0.8 or higher, however, will offer a smoother, more uniform distribution of light in precision-sensitive sectors like assembly or quality control.
Tip: Because of their broad beam angles, UFO LED high-bay lights are a great way to achieve consistent coverage in big areas. For spaces with lower ceilings, linear LED lights provide better light distribution and efficiency.
Reducing Glare: Protecting Workers’ Eyes
Glare can be a major concern in production operations, particularly in areas with reflecting surfaces or strong light sources. High brightness can cause eye strain, headaches, and even accidents. Choose lighting fixtures with equally distributed diffusers or optical lenses to solve this.
A safer and more comfortable working environment can also be achieved by properly positioning lights to prevent direct exposure and reflections from shiny surfaces.
Environmental Factors: Choosing the Right Fixtures
Certain industrial locations may have unique environmental conditions that call for specific lighting. High humidity, harsh temperatures, and hazardous situations can all have an impact on the sort of lighting you choose.
- High Humidity: For high-moisture locations, such as food processing facilities or breweries, use lighting with a high IP rating (e.g., IP65) to protect against dust and water.
- Explosion-Proof Areas: Explosion-proof lighting is important in oil and gas or chemical manufacturing facilities. Make that the fixtures have the necessary certifications (such ATEX or IECEx) to be used in hazardous environments.
- Corrosion Resistance: If your factory works with corrosive chemicals or dust, lighting systems with corrosion-resistant enclosures will assure the fixtures’ longevity and safety.
Smart Controls: The Future of Factory Lighting
Static lighting is not necessary in factories. In order to optimize energy consumption and operational effectiveness, smart lighting systems offer real-time adjustments and automatic control. Your lighting system’s lifespan can be extended and energy consumption greatly decreased with the help of motion sensors, timers, and sun harvesting technologies.
Dimming and scheduling: You may save electricity and maintain the right illumination levels by adjusting lighting routines and dimming options. For instance, while not in use, lighting in low-traffic areas can be automatically turned off or dimmed.
Predictive Maintenance: Reducing Downtime
The capacity of modern lighting systems to communicate with smart building technologies to facilitate predictive maintenance is one of its main advantages. Sensors, for example, can identify when a fixture is nearing the end of its useful life and send out an alert to arrange maintenance before it fails. This decreases downtime and the overall cost of maintenance.
The ROI of Upgrading Your Factory Lighting
When it comes to changing your lighting system, the initial expense may be a concern. Nevertheless, the initial investment will be swiftly recouped by the energy savings and reduced maintenance expenses.
Calculating Energy Savings
Here’s an easy calculation to estimate the energy savings from switching to LED lighting:
If you replace 400-watt metal halide fixtures with 150-watt LEDs, the energy savings can be estimated as follows:
Multiply (old power consumption – new power consumption) by operational hours and energy cost per kWh to determine energy savings.
For instance, switching to LEDs from 100 fixtures that are used ten hours a day could result in daily energy savings of around $30.
ROI Calculation: Payback Period
Divide the initial investment by the yearly energy savings to determine the return on investment. If your LED update costs $20,000 and you save $10,000 per year on electricity, your payback period will be two years. Following that, the savings continue to accrue directly to your bottom line.
Real-World Example: A Confectionery Factory
Take, for instance, a confectionery factory in Jordan. The company’s antiquated fluorescent and CFL lighting needed a lot of electricity and upkeep. The 183-lamp lighting system cost about $2,910 and used 26,665 kWh annually.
After upgrading to LED fixtures, which included 169 pieces of 14W LEDs and two units of 400W LEDs, yearly energy usage reduced to 10,156 kWh, lowering lighting expenditures to $1,095 per year. This resulted in annual savings of $1,815, demonstrating that the update is not only cost-effective but also long-term sustainable.
