With the increasing demand for both energy conservation and efficiency in the industrial lighting sector, LED lamps, leveraging their advantages such as high efficiency, long lifespan, and environmental friendliness, have gradually become the mainstream lighting solution for industrial scenarios like factories, warehouses, and logistics centers. However, the industrial lighting environment is complex, and different areas have significantly different requirements for light intensity, coverage range, and usage duration. Directly applying general standards can easily lead to resource waste or insufficient lighting. The following provides a systematic guide for selecting the power of LED lamps for industrial lighting based on actual needs.
1. Clarify the lighting demand positioning of industrial scenarios
Industrial lighting needs to be based on the 细分需求 (subdivided needs) of space functions:
- High-precision operation areas (such as precision processing workshops): Need to meet the illuminance standard of 1000-1500 lux. The lamp power must match the equipment layout to avoid glare interfering with operations.
- Large warehouse and logistics areas: Need to balance vertical lighting and ground illuminance. It is recommended to use 150W-300W high-pole lamps, with an installation height of 8-15 meters.
- Safety passages and emergency lighting: Need to comply with the GB50034-2013 standard. The power selection must balance the continuous power supply capacity and energy efficiency.
2. Quantitatively evaluate the lighting area and space structure
Obtain key parameters through 3D modeling or on-site surveying and mapping:
- Space height: Workshops with a floor height of less than 6 meters are suitable for 60-100W industrial and mining lamps; elevated warehouses with a height of 8-12 meters require 200-400W high-bay lamps.
3. Dynamically match lighting duration and energy consumption thresholds
Establish an energy consumption-benefit analysis model:
- 24-hour continuous operation areas: Use lamps with intelligent dimming functions, reduce the basic lighting power by 30%, and add human body sensing modules to achieve dynamic energy savings.
- Intermittently used areas (such as platform loading and unloading areas): Equip with time-controlled switches, set power output according to actual usage periods to avoid ineffective lighting.
- Energy efficiency benchmark: Target energy consumption per unit area ≤ 5W/㎡, and prioritize LED products with luminous efficiency ≥ 150lm/W.
4. Construct a full-life-cycle cost evaluation system
Comprehensively consider initial investment and operation and maintenance costs:
- Lamp lifespan: Choose products certified by professional test reports. The lifespan when light decay reaches 70% should be ≥ 50,000 hours to reduce mid-term replacement costs.
- Driving power supply: Adopt isolated constant current power supplies with MTBF ≥ 100,000 hours to reduce maintenance frequency caused by power supply failures.
- Intelligent control system: Deploy an intelligent lighting management system to realize group control and energy consumption monitoring, with long-term energy-saving benefits up to 30%.
5. Strictly control lighting quality and safety standards
Comply with special specifications for industrial lighting:
- Color rendering index: Ra ≥ 80 for mechanical processing areas and Ra ≥ 90 for quality inspection areas to ensure accurate color reproduction.
- Explosion-proof grade: For dust/flammable gas environments, choose Ex d IICT6 grade explosion-proof lamps, and their power configuration must meet explosion-proof certification requirements.
- Glare control: UGR value ≤ 19, adopt deep-cavity anti-glare design or grid lenses to ensure visual comfort for operators.
6. Implement phased verification and optimization
Establish a closed-loop for lighting effect evaluation:
- Simulation verification: Use DIALux software for 3D lighting simulation to generate is illuminance curves and pseudocolor maps.
- On-site testing: Install sample lamps in typical areas, measure the actual illuminance of the working surface with an illuminance meter, and the error should be controlled within ±15%.
- Dynamic optimization: Adjust lighting strategies according to seasonal changes (such as shortened daylight hours in winter), and use natural light compensation technology to reduce lamp power output.
The selection of industrial lighting power is a systematic project that needs to balance initial investment, operating costs, lighting quality, and safety compliance. It is recommended to adopt an iterative method of “demand analysis – scheme simulation – on-site verification – continuous optimization” and combine IoT technology to realize intelligent management of the lighting system. The ultimate goal is not only to select lamps with appropriate power but also to build an efficient, reliable, and scalable industrial lighting ecosystem.
