As a composite service industry integrating transportation, warehousing, freight forwarding and information, modern logistics is the product of economic globalization and an important service industry to promote 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 national GDP, and the average growth of cargo throughput has reached nearly 20%. The warehousing business has shown a rapid development momentum.
In the context of the unprecedented prosperity of the logistics industry, global logistics giants have begun to establish highly automated, multi-functional, high-density modern logistics hubs around the world to improve the efficiency of logistics operations, which directly drives storage lighting to 20% per year. The market needs to grow. The lighting lighting requirements for lighting functions are also upgraded from the most basic “with lights†to high quality, high efficiency and energy saving. The efficient LED lighting system improves the efficiency of logistics operations, while reducing the failure rate and guarantee. Operational safety and reduced operating costs of the company play a key role.
According to the height of the warehouse building, the installation status of the lamps can be generally divided into three types: low ceiling, medium ceiling and high ceiling. The low ceiling generally has a height of less than 5 meters; the middle ceiling is generally installed at a height of 5 to 10 meters; the high ceiling is installed at a height of more than 10 meters, and more than 300W lamps are required.
Second, the warehouse lighting features
Today, as global energy is getting tighter, the energy saving of industrial lighting systems is the trend of the times. High-quality industrial lighting not only can meet the extreme environment of industrial production, reduce energy consumption, but also a more comfortable visual environment helps employees to significantly relieve long-term work fatigue, maintain a good working condition, and thus improve production efficiency, Reduce the work error rate, improve the pass rate, reduce production safety accidents, etc., and ultimately improve the effectiveness of corporate value.
For lighting, according to the visual requirements, the nature of the work and the environmental conditions, select the appropriate illuminance, take appropriate brightness distribution and uniformity of illumination, reduce unnecessary shadows, make the visual space clear; correct choice of light source and lamps, limit glare Improve the safety of operations and activities under lighting; require no stroboscopic to reduce irritability and uneasiness; rationally select the light source to reduce the adverse effects of light and ultraviolet radiation on people and objects; handle light color and color rendering The choice of index makes it harmonious and harmonious, creating a favorable color-setting environment for work and life, and creating a light environment that makes people work and activities feel relaxed, comfortable and beautiful.
When replacing the light source, environmental protection and energy saving requirements should be considered. At the same time, the light source with the longest life should be selected to reduce the manpower and material resources of the lamp replacement; improve the visual conditions, make people feel relaxed and happy under the light and reduce the light environment pollution.
Third, the warehouse lighting considerations
1. Meet the requirements of night work
Not only at night, many visual operations are indoor operations, even in the daytime, artificial lighting is required, and the lighting effect cannot be completely comparable to natural lighting. If the lighting level is not enough, the visual characteristics are insufficient to cause an increase in the operational error rate or speed. Reduce; even with higher illumination to ensure better visual characteristics.
In terms of the visual effect of lighting, the lighting should be carried out through reasonable lighting calculations according to the corresponding lighting standards and the needs of the actual site to ensure a certain level of lighting and reduce the drop 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. Satisfy the need for brightness while giving a sense of visual comfort
The impact of the ceiling and walls of the warehouse on the lighting effect is related to the room size. The ceiling of the small room has a small proportion of the field of view, the influence of the contrast is small, and the proportion of the wall in the field of view is large, and the influence of the contrast is large. Therefore, the small room can use the wall with high reflectance and the ceiling with low reflectance. Conversely, large rooms use high reflectance ceilings and low reflectance walls. A moderately uniform illumination is achieved through effective lighting arrangements. The lighting requirements are bright and clear, with no glare and no ghosting.
The warehouse illumination requirements are as follows:
Conventional sodium lamp needs to be preheated when starting, if it is powered off, it needs to be cooled and preheated before it can be started; the current harmonic of sodium lamp is large; the sound of harsh current is emitted; the surface temperature of the bulb is as high as 360 °C, and the ambient temperature is obviously felt under the sodium lamp. Increased; low color rendering, the color deviation under the light, poor visual effect; stroboscopic effect is serious, the naked eye directly observes small objects blurred, glare, environmental depression. Obviously, it is impossible to work comfortably under the sodium light, which reduces work efficiency.
3. Meet the requirements of energy saving, low carbon and environmental protection
As we all know, energy consumption is mainly concentrated in the industrial sector. According to relevant media reports, last year, Guangdong's industrial energy consumption accounted for 63.9% of the province's energy terminal consumption. The “big head†of reducing industrial energy consumption is the top priority in energy conservation and consumption reduction, and vigorously promote the application of energy-saving lighting products. The trend of the times.
China's energy situation is becoming more and more tense, and energy shortages have brought huge impacts on manufacturing industries known for their energy consumption. Manufacturing companies are taking the road of energy conservation is the trend of the times. Enterprises have more than 20% energy saving potential. Due to the lack of energy-saving renovation funds and energy-saving consulting services, the heavy energy costs have greatly increased the cost of enterprises, which not only makes the power supply tight, but also pollutes our living environment.
For example, a conventional sodium lamp has the disadvantages of low luminous 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 efficiency.
Fourth, the use of lighting for warehouse lighting
According to the height of the warehouse building, it is recommended to install a low-ceiling LED high-altitude lamp ; in the middle ceiling and high ceiling, it is recommended to install a 300W LED ceiling light .
The efficiency of LED high-power lamps is as high as 85-90lm/W, which has obvious advantages compared with traditional metal halide lamps and high-pressure sodium lamps. The energy saving rate is over 75%, the service life is almost 10 times that of traditional lamps, and there is no light pollution. Provides adequate, uniform illumination for industrial lighting locations such as warehouses, workshops, and factories. It can provide a good and comfortable lighting environment for long-time visual work people; and can properly relieve the operator's visual fatigue. Unique light distribution technology, uniform light spot. The color rendering is good, close to the natural light, and the real color is more realistic. Various light colors are available to meet the needs of different environments, eliminating the depression caused by the high or low color temperature of traditional lamps, making the vision more comfortable and improving the work efficiency of workers. In addition, the high-power LED lamps adopt constant current and constant voltage control, and the applicable voltage width (AC100V-240V) overcomes the instability of the lighting caused by the ballast, the noise pollution caused by the ballast. No flicker and noise, no stroboscopic hazard, visual observation of small objects is true and clear, and the lighting environment is bright and comfortable to avoid the irritation and fatigue brought to the eyes during work. Strive to provide the best LED lighting source for warehouse and work lighting.
