The task of factory enterprises is to ensure that the operators of the equipment work in a safe and reliable lighting environment with suitable brightness. The professional LED lighting solution can ensure the safety of personnel and the safe operation of equipment, detect equipment failures in time, and improve the efficiency of equipment maintenance and inspection. So as to improve the system's electrical transport level and ensure the reliability of the system. To ensure a safe and reliable working environment is our common desire with the industry.
At present, energy saving and emission reduction has become a basic national policy. Facing the weakness of the current power market, the pilot of the decline in load rate and the economic dispatch of energy saving, the depth of the potential and energy saving is a task that the enterprise must promote.
The current situation of lighting in domestic enterprises:
Now the lighting level of the factory still stays in the four and 50s of the last century. The lighting source is still using incandescent lamp, mercury lamp, high pressure sodium lamp, low efficiency, poor color display, poor lighting effect, waste of energy, poor running quality and high maintenance cost. From the perspective of new power plants, many of the illuminator designed and manufactured are outdated products, which are still equipped with relatively backward appliances and light sources. For old power plants, there is no special transformer for lighting, the voltage fluctuation is greater, and the damage to the illuminator is more prominent. The actual situation of the power plant is: the voltage fluctuation is large, and the voltage is high, the environment temperature of some places is high, the dust is much, and the environmental conditions are poor.
In view of the lighting environment characteristics of factory enterprises, high requirements are put forward for the matching lighting fixtures, which are not only aseismatic, high temperature resistant environment, long life, and wide range of voltage adaptation, but these requirements are the advantages of semiconductor LED lighting fixtures.
The characteristics of future economic and social life -- low carbon economy
Low carbon economy (low energy consumption, low pollution and low emission) is a fundamental change in the concept of human survival and development.
1. The background of LED lighting:
The history of the development of A and lighting
The development history of lighting is a history of human evolution. With every change of mankind, lighting technology has made a qualitative leap. Ancient wood drilled by mankind has opened a new chapter in the history of human illumination.
In 1879, Edison finally lit the first practical electric lamp in the world through repeated experiments.
In 1938, Iman of the Universal Electronics Inc of the United States invented the traditional fluorescent lamp. This fluorescent lamp is a tubular lamp with a certain amount of mercury injected into the tube. The inner wall of the lamp tube is coated with phosphor, and there is a filament at both ends of the lamp. When energized, the electrons emitted from the electrodes collide with the mercury atoms, causing ionization of the mercury atoms to ionize and emit ultraviolet light, and ultraviolet light stimulates phosphor emission.
In 1978, Holland PHILPS first invented the electronic energy-saving lamp, also called the compact fluorescent lamp. Because of his high light efficiency (5 times the ordinary light bulb), the energy saving effect was obviously long life (6-8 times the ordinary light bulb), and the advantages of small volume and convenience were paid attention to and welcomed by the people and the country.
In 1962, the first LED light source was born, and now it has broken through the bottleneck of the semiconductor lighting technology industry and developed a series of LED lighting products which are more efficient, energy saving, more environmentally friendly and longer life, which will completely subvert the traditional lighting age.
Development trend of industrial lighting
1, more use of functional lighting (local key lighting). More emphasis on local lighting is conducive to the humanization of the working environment, and is conducive to energy saving and subdivision of the working environment.
2, establish appropriate lighting standards according to different users, such as age and visual acuity.
3, the working environment is more natural and comfortable with the help of good lighting.
4. In order to improve the comfort of lighting, the evaluation mode of indoor glare (UGR) has already entered the national lighting standard regulation range. Because the calculation method of UGR depends on the characteristics of lamps and lanterns in a large way, the design ability of the lamps and lanterns of the manufacturer is higher.
5. In many industrial production environments, a considerable number of conditions are established in the angle of vertical observation. Therefore, the vertical illumination of the lighting is also required, especially in the field inspection operation, and the strict requirements for the vertical illumination are inseparable.
6. Different production environments require different illuminance balance. Sometimes the key parts need to be illuminated. Sometimes the index of uniformity should be increased very high.
