With the development of industry, all kinds of products need production and processing. The factory workshop is inseparable from the lighting. In order to ensure the production of workers and the smooth operation of the inspection work, a good lighting fixture is needed in the workshop workshop to meet the needs of the workers' work. LED industrial and mining lamps are mainly used to replace traditional high power industrial luminaires for industrial lighting and other complex environments. So where are the characteristics of the LED industrial and mining lights?1, LED industrial and mining lamp service life long, LED as solid cold light source, epoxy resin package, no light emission, heat deposition, light failure and other shortcomings, LED industrial and mining lamps in the appropriate current and voltage, the service life of up to 60 thousand to 100 thousand hours, LED industrial and mining lights longer than the traditional light source life longer than 10 times.2, environmental protection, LED industrial and mining lights are made from non-toxic materials, unlike fluorescent lamps containing mercury will cause pollution, while LED can also be recycled. LED industrial and mining lamp spectrum does not contain ultraviolet and infrared rays. Unlike traditional light sources, it is surrounded by many mosquitoes around lamps. No heat, no radiation, little glare, cold light source, safe touch.3, LED industry and mine have high lighting efficiency and high luminous efficiency.4, LED industrial and mining lamp adopts constant current driving power, high PF value, no power grid pollution.5. It has the advantages of low power consumption, light weight and so on.As we all know, the disadvantage of LED lamps and lanterns is that the temperature is too high. How can we do better to solve the heat dissipation problem of LED industrial and mining lamps?The life of the LED lamp depends largely on the heat dissipation level of the lamps and lanterns, and the main way to improve the heat dissipation is to pass the excess heat generated by the chip through the heat sink and heat sink. At the same time, the main parameters related to the LED heat dissipation are thermal resistance, nodal temperature and temperature rise.Thermal resistance refers to the difference between the effective temperature of the device and the temperature of the external reference point, divided by the quotient of the steady-state power dissipation in the device. It is the most important parameter to indicate the degree of heat dissipation.Junction temperature refers to the temperature of the semiconductor junction in the main heating part of the LED device. It reflects the temperature value of LED devices under working conditions. The heat resistance of chips and phosphors is very high, which basically has no effect on the life of the devices.The temperature rise of the tube shell - the temperature rise of the environment. It refers to the difference between the shell temperature and the ambient temperature of the LED device. It is a temperature value that can be measured directly, and it can directly reflect the degree of heat dissipation in the peripheral of LED devices. If Wen Sheng is too high, the maintenance rate of LED light source will be greatly reduced.In addition, the design of LED lamps and lanterns, in addition to improving the efficiency of the lamps and lanterns, the requirements of light matching and the appearance of the appearance, should also improve the heat dissipation of the lamps and lanterns. The heat conduction materials are used and some nano materials are applied to the heat dissipating body. The thermal conductivity of the lamps is increased by 30%. In addition, it is necessary to have better mechanical and sealing properties. The radiator must be dust-proof. The temperature rise of LED lamps should be less than 30 degrees.

    In the field of LED industrial lighting, most of the lamps are single in shape, simple in design and cumbersome in installation. It's like walking through a manual workshop in 80s.After doing a lot of market research, Shang hung has found that besides the performance of lamps and lanterns, customers also have higher requirements for appearance. Combining the technical experience of Shang hung lighting and the introduction of UFO Tiantan's flying saucer high shed industrial and mining lamp, it combines the inherent high performance + appearance high color value. 鳍片散热+PC高光效透镜Good cooling system will greatly improve the life of lamps and reduce the decay of light.

A simple iron chain can hold him firmly in his post. No need for tedious, only to let you save.                                          The style of life lies in your taste, and the quality of the product lies in your choice. Only choose the right time will prove your rationality and vision.The premise of the service is profit, the profit space can be squeezed, but it can not disappear, otherwise there will be service along with the loss of profits.Making lamps and lanterns is a conscience. We would rather explain the price for a while, and never apologize to customers for their quality.“抢别人的单，断自己的路！”以低价接单的企业只看重眼前利益，看似迫不得已的个体选择却在危害行业整体的健康发展。这样的经营模式持续不了多久，而且在行业转型升级的过程中，企业也丧失了从产品开发、工艺创新等方面提升的能力，其发展道路只能越走越窄，到头来会发现这是条死胡同。其实，在价格战的博弈中，企业完全可以靠挖掘自身优势，获取更多利益。——靠产品说话，完胜价格战！

About the enterpriseThe 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 economyLow 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 lightingThe 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 lighting1, 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.

New technologies, new materials and new technologies are constantly applied to the design of high-power LED light sources, laying a solid foundation for the design of high-power LED lamps and lanterns. In LED lamps and lanterns, the important components are three parts: drive, light source and heat dissipation.1. DriveThe power supply is a high quality, high efficiency and high stability LED water proof constant current driving power specially designed for LED. With quick start, wide compatible load range and complete protection function, the import voltage AC85-265V, high precision constant current control, high efficiency and reliable performance, and the appearance structure of all aluminum will make LED lamps more safe and stable.2. Light source selectionAt present, high power LED light sources are more famous brands: CREE, OSRAM, NICHIA, Lumileds (the earliest LED), in addition, the Taiwan manufacturer's crystal element, Addison and the domestic packaging plant Shenzhen Wan run, Zhuhai Ruifeng, Jiangxi LIAN and so on are also more popular brand.3. Heat dissipation designIn high power LED, heat dissipation is a big problem. For example, if the 1 10W white light LED has the photoelectric conversion efficiency of 20%, the electrical energy of the 8W is converted into thermal energy. If no heat dissipation is used, the core temperature of the high power LED will rise rapidly, and when its junction temperature (TJ) rises above the permissible temperature of * * (generally 150), the high power LED will be damaged by overheating. Therefore, the heat dissipation design is also the most important content. The following are the two aspects of aluminum substrate and radiator to explore the heat dissipation design.3-1, substrate selectionIn the application of LED products, it is usually necessary to assemble multiple LED light sources on a circuit substrate. In addition to the role of the structure of the LED module, the circuit board, on the other hand, has to play the role of heat dissipation as the output power of the LED becomes higher and higher, so as to send out the heat generated by the LED crystal. Therefore, the material selection must take into account the requirements of the structural strength and heat dissipation. For substrates, we compare FR4, ceramic substrate and MCPCB. respectively.(1) the thermal conductivity of FR4 is about 0.36W/m. K, which can not meet the heat dissipation requirements of high power LED lighting.(2) the thermal conductivity of Ceramic is greater than 80W/m. K, which is expensive, poor workability and can not be used in large area.(3) MCPCB thermal conductivity is greater than 2.0W/m. K, moderate price, strong processing, mature technology, mass production.3-2 radiator designThe function of the radiator is to absorb the heat transferred from the substrate or chip, and then spread to the external environment to ensure the normal temperature of the LED chip. Most of the radiators are carefully designed for natural convection and forced convection. That is, the active radiator and the passive radiator.4, the characteristics of LED industrial and mining lamps:4-1, LED industrial and mining lamps use a single large power LED lamp as light source, using a unique multi chip set single mode group light source design, selected imported high brightness semiconductor wafers, with high thermal conductivity, light fading, pure color, no heavy shadow and other characteristics;4-2, the unique design of heat dissipating body, combined with the electric box, effectively diffusion of heat, thus reducing the temperature in the lamp, effectively ensuring the life of the light source and power.4-3. The surface of the radiator is anodized and anti-corrosive, and the structure is compact and beautiful.4-4, green environmental pollution, no lead, mercury and other pollution elements, no pollution to the environment.4-5. The color display is good, the color of the object is more genuine, the various light and color can be selected. It can meet the needs of different environment, eliminate the depressing emotion caused by the high or low color temperature of traditional lamps and lanterns, make the vision feel comfortable and improve the work efficiency of people.4-6. Using constant current and constant pressure control, the voltage wide is applied to overcome the power grid, noise pollution and light instability caused by the ballast, so as to avoid the stimulation and fatigue in the eye.4-7, the decorative effect is good, the special surface treatment technology is adopted, the appearance is novel, the installation is simple, the disassembly is convenient, and the application scope is broad.
