Factory Lighting Design Summary

Why Factories Use LED Lighting?

For traditional factory lamps, the power consumption is very high, more than three times that of LED lamps. Besides, the average lifespan of traditional lamps is only one year, while that of LED lamps can reach 50,000 hours. The advantages of LED lights are they are energy-efficient, shockproof, waterproof, dimmable, miniature in size, offer high bright light and environmental protection.

During the procurement process, the factory purchasing managers prefer to choose LED lamps with the appropriate wattage depending on the actual situation. Factory LED lights have a longer lifespan and more stable performance, thereby helping save on maintenance costs.

Production Line
For factory lighting designers, the lighting of production line areas can be a tricky task. A good light facilitates visual tasks and helps avoid mistakes. The minimum requirement is 300 lux, but we should strive for 500 lux at the manual processing workbench. Here we have Lepro 150W UFO high bay light with 19,000 lumens that provide enough reliable light from significant heights without compromising lighting comfort, glare control, and energy efficiency.

Goods Storage
Factory storage rooms must utilize the storage space to the maximum to reduce storage costs. As a result of the aisles of storage areas being narrow and long, it is difficult for the lighting to cover the entire space. To avoid shadowy areas and ensure the safe driving of trucks and the clear visibility of various shelves, goods, and labels, the lighting system must have uniform illumination and high vertical illumination. The Lepro LED linear high bay light guarantees excellent light accessibility, clear readability, and good glare-free upward visibility.

Shipping Area & Open Area
Lepro wall pack lights and flood light are designed to light up outdoor open areas. For example, Lepro 120W LED wall pack light gives businesses optimal energy efficiency and cost savings and also provides safety, security, and aesthetic appeal. As experts in the LED lighting industry, Lepro outdoor lighting fixtures provide businesses with affordable, environmentally-friendly warehouse and exterior building lighting.

Outdoor Parking Lot & Street
The waterproof Lepro 200-watt shoebox light is equivalent to a 1000-watt traditional lamp. It is an excellent option for large areas that need sufficient light, such as the parking lots and streets. It is designed to work in an environment with temperatures from -4°F to 104°F. The premium aluminum housing of the light not only helps prevent impact but also effectively dissipates heat. The light’s IP65 waterproof and 10kV surge protection (L-PE wiring) ensure safety in almost all-weather conditions.

Emergency Lighting
Emergency Lighting is highly significant for factory safety. Partial emergency powered lighting must also be provided in key work areas of the factorymain mechanical, electrical, and communications equipment rooms; security control centers; fire command centers and stairwells. The Lepro 4.2W LED emergency light has an input voltage of 120/277VAC with a built-in 9.6V 600mAh Ni-Cd battery, which provides 90 minutes of emergency operation during a power outage.

Factory Lighting Requirements
Factory lighting must meet the needs of production and inspection. The lighting system of the factory building is usually divided into two types - tall buildings and general factory buildings. For tall buildings above 15m in height, general lighting uses gas discharge lamps as the light source, and lamps with narrower beams (such as deep-lit factory lamps) are mounted under the roof. The spotlights can be installed on walls and pillars, which combine to ensure the required illumination on the work surface.

Appropriate uniform illumination and brightness, ideal light color, and color rendering should be designed according to different areas. For example, the production area uses 3 × 28 W ceiling-shaped fluorescent lamps with shades in high-level warehouses for storing products and materials. In the cargo area, 300W or 400W MH are used, while in the low-span office area, 3X14W grid-recessed fluorescent are installed to meet the comprehensive light requirements of each area. In general workshops, fluorescent lamps can be used as the primary light source, and the arrangement of the lamps can be perpendicular or parallel to the beam.

Factory lighting should be designed in accordance with the following general principles. Mixed lighting should be used for high illumination requirements and low density of working positions in places where general lighting alone is not reasonable. When the illuminance of the operation is not high, or it is not suitable to install local lighting, or it is unreasonable to use mixed lighting due to technical production conditions, general lighting should be used separately. When a certain work area needs the illuminance to be higher than the general illumination, general partition illumination can be adopted. Similarly, when the general lighting of the district cannot meet the illumination requirements, local lighting should be added.
Factory Light Illumination Standard
1. Choose lamps with different light distributions according to the hanging height of the lamps on the workshop frame and the RI value of the room shape index. When RI=0.5~0.8, narrow light distribution lamps should be used; when RI=0.8~1.65, medium-light distribution lamps should be used; and when RI=1.65~5, wide light distribution lamps should be used.

2. Use a LED lighting source with an appropriate color temperature and a high CRI (color rendering index) that meets production requirements.

3. Achieving the specified uniformity of illumination: the uniformity of illumination in general in the work area should not be less than 0.7, and the uniformity of illumination in the vicinity of the work area should not be less than 0.5.

4. Meet the quality requirements for direct glare limitation of lighting. Uniform glare value (UGR) is in accordance with the provisions of GB50034-2004. The general allowable value is 22, while the fine processing value is 19.

5. Take some measures to reduce the impact of voltage fluctuations and voltage flickers on lighting and also prevent strobe effects.
Factory Lighting Scope
(1) Interior lighting: Interior lighting of the production plant, research and development, and office interior lighting.

(2) Outdoor device lighting: Lighting for various outdoor devices such as the kettles, the shipyard's open-air operation site, tanks, reaction towers of petrochemical companies, ladders, rotary kilns, blast furnace furnaces, platforms of metallurgical companies, and gas tanks of power stations.

(3) Station yard lighting: Illumination of stations, railway marshaling stations, parking lots, open storage yards, outdoor test yards and etc.

(4) Underground lighting: Lighting basements, cable tunnels, integrated pipe corridors, and tunnels.

(5) Evacuation lighting: The lighting is effectively identified and used in the evacuation passages in the factory buildings.

(6) Guard lighting: The lighting set up along the perimeter of the factory area and around guard areas of key places.

(7) Obstacle lighting: There are super tall buildings and structures in the factory area, such as chimneys, etc. According to the regional aviation conditions, the signs need to be installed according to relevant regulations.
