Warehouse Lighting

 

The Book of Songs describes poems. we know that the warehouse building has a long history. Modern warehouses think more about operating income than just storage. This is the difference from the old warehouse. Therefore, modern warehouses attach great importance to the reasonable arrangement of aisles, transportation methods and the maximum height of stacking in terms of transportation turnover, storage methods and building facilities, and are equipped with cost-effective mechanized and automated storage facilities to improve storage capacity and work efficiency. . The warehouse is composed of a warehouse for storing articles, transportation and transportation facilities (such as cranes, elevators, slides, etc.), transportation pipelines and equipment to and from the warehouse, fire protection facilities, and management rooms. Warehouses can be divided into solid, liquid, gaseous and powdery goods according to the form of stored goods; they can be divided into raw materials, semi-finished and finished goods according to the nature of the stored goods; according to construction The form can be divided into single-storey warehouse, multi-storey warehouse, and cylindrical warehouse.

Warehouse  features

According to the height of the warehouse building, the installation status of the lamps can be generally divided into three types: low ceiling, middle ceiling, and high ceiling. Low ceilings are generally less than 5 meters in height; middle ceilings are generally installed at 5 to 10 meters; high ceilings are installed at heights of 10 meters or more, and lamps of 300W or more are required.

The importance of warehouse lighting

For a modern warehouse, not only the building should be spacious and generous, and all kinds of lighting equipment must be complete, and it must have a good lighting environment and a complete fire protection system. Enables people to clearly see the conditions in the warehouse. In addition to ensuring that the cargo pile is met, the completeness of fire fighting equipment must also be ensured to ensure that the fire is the rescue of the cargo and the evacuation of personnel. Because the warehouse needs to keep dry and ventilated, the light in the warehouse is generally poor. So lighting is especially important.

Warehouse lighting precautions

1.Meet the requirements of night work

Not only at night, because many visual tasks are indoor operations, artificial lighting is required even during the day, and its lighting effect cannot be completely comparable to natural lighting. If the lighting level is insufficient and the visual characteristics are insufficient, it will cause an increase in the operating error rate or speed. Reduced; even with higher illumination to ensure better visual characteristics.

In terms of the visual effect of lighting, the lighting should be arranged through reasonable lighting calculations in accordance with the corresponding lighting standards and actual site requirements to ensure a certain level of lighting and reduce the decrease in work efficiency caused by insufficient lighting. A light source that guarantees a certain color rendering index in a relatively dim environment to improve effective light efficiency.

2.Meet the needs of brightness while giving a sense of visual comfort

The effect of the ceiling and walls of the warehouse on the lighting effect is related to the room area. The ceiling of a small room has a small proportion in the field of view and has a small influence on contrast, and the wall has a large proportion of the field of view and has a large degree of contrast. Therefore, a small room can use a high reflectance wall and a low reflectance ceiling. Conversely, large rooms use high-reflection ceilings and low-reflection walls. Through effective lighting arrangements, a moderately uniform illuminance is achieved. The lighting requirements are bright and clear without glare and ghosting. Traditional sodium lamps need preheating to start. If the power is cut off in the middle, you need to cool down and preheat before you can start the sodium lamp. The current harmonics are loud; a harsh current sound is emitted; the surface temperature of the bulb is as high as 360 ℃, and the ambient temperature is obviously increased under the sodium lamp High; low color rendering, the color deviation under the light, the visual effect is poor; stroboscopic effect is serious, direct observation of small objects with the naked eye is blurred, the light is dazzling, and the environment is depressed. Obviously, it is impossible to work comfortably under the sodium light, which reduces the work efficiency.

3.Meet the requirements of energy saving, low carbon and environmental protection

In today’s increasingly tight global energy, energy saving in industrial lighting systems is the general trend. High-quality industrial lighting not only satisfies the extreme environment of industrial production and reduces energy consumption, but also a more comfortable visual environment helps employees to significantly alleviate long-term work fatigue and maintain good working conditions, thereby improving production efficiency, Reduce work error rate, increase qualification rate, reduce production safety accidents, etc., and ultimately improve the effectiveness of corporate value. For lighting, you should choose the appropriate illuminance according to the visual requirements, the nature of the work, and the environmental conditions, adopt appropriate brightness distribution and uniformity of lighting, reduce unnecessary shadows, and make the visual space clear; properly select light sources and lamps to limit glare , To improve the safety of work and activities under the light; no flicker is required to reduce irritability and anxiety; the light source is selected reasonably to reduce the adverse effects of light and heat and ultraviolet radiation on people and objects; handle the light color and color rendering The choice of the index makes it coordinate and harmonious, and creates a favorable color discrimination environment for work and life, so as to create a light environment that makes people feel relaxed, comfortable and beautiful in their work and activities. When replacing the light source, we should consider the requirements of environmental protection and energy saving; at the same time, select a light source with a longest life as possible to reduce the manpower and material resources for changing the light; improve the visual conditions so that people feel relaxed and happy under the light and reduce light environmental pollution.

Selection of electric light source

There are mainly two types of commonly used electric light sources for lighting:-Types are heat radiation light sources, which are light sources made using the principle of radiant luminescence of matter through electrical heating, such as incandescent lamps, tungsten halogen lamps, etc .; the other is Gas discharge light source, which is a light source made by the principle of light emission during gas discharge, such as fluorescent lamps and high-intensity gas discharge lamps. Determination of electric light source, evacuation of staff. Because the warehouse needs to keep dry and ventilated, the light in the warehouse is generally poor. So lighting is especially important. According to the different places of use, the light source’s light efficiency, color rendering, life, start ignition and restart ignition time and other light characteristics indicators, and the impact of environmental conditions on the photoelectric parameters of the light source should be reasonably selected.

The warehouse should generally use natural lighting. If lighting is really needed, incandescent bulbs should be used. Their power should not exceed 60W. It is strictly forbidden to use fluorescent lamps and iodine tungsten lamps. The wiring and the installation of light bulbs should be above the aisle and the distance from the stacking of goods. It should be kept at least 50CM. especially important.

Requirements for warehouse lighting fixture

It depends on the type of warehouse (whether it stores flammable, explosive or chemicals), size, height, etc. For warehouses that store flammable, explosive or chemicals, use explosion-proof lamps. If it is an ordinary warehouse, the height is average, and the contrast requirement is not very high, you can use general indoor lighting (such as lamps, flood lights, etc.); if the height of the warehouse is high, you must choose a higher power mining lamp, LED investment Light lamp etc. However, they must meet the relevant lighting standards. According to GB 50034-2004 “Architectural Lighting Design Standards” in warehouse lighting,

1.Meet the requirements of warehouse lighting illuminance. Generally speaking, the ground illuminance of the warehouse should not be less than 50lux, in order to facilitate the identification of cargo labels, etc .;

2.Energy saving: realize the intelligent control of the lighting system, realize the two-way lighting of the warehouse, one road can be closed during the day, and two roads at night to save energy;

3.Safety: Explosion-proof lighting fixtures with waterproof, dust-proof and anti-corrosion performance should be used to ensure the safe operation of the lamps;

4.Long life: In order to avoid the increase of maintenance costs in the later period and ensure the timely maintenance and replacement of lamps, lamps with long life and high stability should be selected;

5.Restartability: Consider lamps that can be restarted instantly to avoid excessive delay time for lamps.

Why we choose LED lights to use in the warehouse

As a composite service industry integrating transportation, warehousing, freight forwarding, and information industries, modern logistics is a product of economic globalization and an important service industry that promotes economic globalization. As a core component and an important pillar of logistics enterprises, warehousing plays a vital role in the logistics system. In recent years, the growth of the total output value of the warehousing industry has continuously exceeded the growth rate of the country’s GDP, the average increase in cargo throughput has reached nearly 20%, and the warehousing business has shown a rapid development momentum.

Relevant media reported that Guangdong ’s industrial energy consumption accounted for 63.9% of the province ’s final energy consumption last year. The “big head” of reducing industrial energy consumption is a top priority in energy conservation and consumption reduction. It is a general trend to vigorously promote the application of energy-saving lighting products . The requirements of warehouse lighting for lighting functions have also been raised from the most basic “with lights” to a high-quality, efficient and energy-saving height. The efficient LED lighting system has improved the efficiency of logistics operations, while reducing the failure rate, ensuring operation safety and reducing Corporate operating costs play a key role.

Contrast defects of traditional lamps and LED lamps

For example, traditional sodium lamps have the disadvantages of low light efficiency, insufficient illumination, poor safety, high energy consumption, low color rendering, inability to start when the voltage is unstable, frequent replacement, large workload, and large thermal benefits. The energy situation in China is becoming tight, and the energy shortage has brought a huge impact on the manufacturing industry, which is famous for its energy consumption. It is the general trend that manufacturing enterprises take the road of energy saving. Enterprises have more than 20% of energy-saving potential. Due to the lack of energy-saving transformation funds and energy-saving consulting services, heavy energy consumption costs have greatly increased the cost of the enterprise, not only made the power supply tight, and polluted our living environment.

Product features of LED lights

LED lights have emergency function

It can be used for normal working lighting and emergency lighting. It integrates type A emergency lighting and type B emergency lighting. Type A is normal lighting when there is mains power, and it is automatically switched to emergency lighting when there is a power failure; Type B is when the lamp is off when there is mains power, and emergency lighting is automatically started when there is a power failure. The two emergency modes can be switched freely, and can also be controlled by an external emergency switch.

LED lamp safety and reliability

The emergency power supply uses polymer lithium batteries, which are safe and efficient, and have a long service life. Adopt wide voltage design 110V ~ 260V. The anti-glare lamp cover is used to make the light softer, without glare, which will not cause the operator’s eyes to be tired and improve the work efficiency; good electromagnetic compatibility will not cause pollution to the power supply. The transparent parts are made of imported bullet-proof rubber materials, with high light transmittance and good impact resistance, which can make the lamps work normally in a variety of harsh environments. The shell is made of lightweight alloy material, which is wear-resistant, corrosion-resistant, waterproof and dustproof. Humanized design: It can switch the emergency function automatically / manually.

Energy efficiency

The light source adopts American Cree LED, with high brightness, long life, low thermal resistance, low power consumption, and meets the “energy star” standard. Compared with incandescent lamps of the same brightness, it saves about 90% of power, and saves about 60% of power compared with the energy-saving lamps on the market. The drive circuit of constant current output has short circuit and open circuit protection functions, and the output brightness does not change with the change of voltage. The average life of the light source is 100,000 hours, which can achieve long-term maintenance-free.

LED high-power line mining lights have an efficiency of more than 110lm / W. Compared with traditional metal halide lamps and high-pressure sodium lamps, they have obvious advantages. The energy saving rate is more than 75%. The service life is almost 10 times that of traditional lamps, and there is no light pollution. It can provide sufficient and uniform lighting for industrial lighting places such as warehouses, workshops, and factories. It can provide a good and comfortable lighting environment for the long-time visual work crowd; and it can appropriately relieve the operator’s visual fatigue. Unique light distribution technology, uniform light spot. Good color rendering, close to natural light, and more true to the actual color. Various light colors are available, which can meet the needs of different environments, eliminate the depressed mood caused by the high or low color temperature of traditional lamps, make the visual sense more comfortable, and improve the work efficiency of workers. In addition, the high-power LED line mining lamp adopts constant current and constant voltage control, and the applicable voltage width (AC100V-240V) overcomes the power grid, noise pollution and lighting instability caused by the ballast. No flicker and noise, no stroboscopic hazards, small objects are clearly visible to the naked eye, and the lighting environment is bright and comfortable, avoiding irritation and fatigue caused to the eyes during work. Strive to provide better LED lighting sources for warehouse and work lighting.

Warehouse Lighting Arrangement

The International Commission on Illumination (CIE) ‘s “Guide to Lighting in Warehouses” stipulates that the minimum illumination for windowless warehouses must not be less than 5001x. According to China’s current power level, the illumination standard of artificial lighting in China is generally lower than that in Europe, the United States and other countries. In fact, recently, the illuminance of some Chinese-foreign joint ventures and wholly foreign-owned clean factories is much higher than 2001x, reaching 300 ~ 5001x. For working in closed warehouses For operators, providing them with a bright and comfortable visual environment can greatly improve production efficiency and yield of fine products. The general lighting in the hybrid lighting of the warehouse without daylighting windows is not less than 2001x, which is one level higher than 1501x in GBJ73-84.

Development Trend of Warehouse Lighting

In recent years, the growth of the total output value of the warehousing industry has continuously exceeded the growth rate of the country’s GDP, the average increase in cargo throughput has reached nearly 20%, and the warehousing business has shown a rapid development momentum. Energy consumption is mainly concentrated in industrial industries. The “big head” of reducing industrial energy consumption should be the top priority in energy conservation and consumption reduction. It is a general trend to vigorously promote the application of energy-saving lighting products.

Against the background of the unprecedented prosperity of the logistics industry, global logistics enterprise giants have begun to build highly automated, multifunctional, high-density modern logistics hubs around the world to improve logistics operation efficiency, which directly drives warehouse lighting to 20% The market needs to grow, and the requirements of warehouse lighting for lighting functions have also been raised from a more basic “with lights” to a high-quality, efficient and energy-saving height. Efficient LED lighting systems have improved the efficiency of logistics operations, while reducing failure rates and guarantees. Operational safety and reducing operating costs play a key role.
