Energy, long life, applicability, due to the small size of the single LED can be made into any shape, short response time, environmental protection, non-hazardous metal waste recycling easy, colorful, luminous, pure color and narrow spectral range, and through red, green and blue primary colors blending into a colorful or white.

LED fluorescent light and ordinary fluorescent LED fluorescent lamps have shortcomings as follows: expensive, generally do light efficiency, and theoretical light efficiency there is a big gap between the life and theories of life, can do a big gap, or heat, light failure can also be narrowed significantly.

Advantages:

An environmentally friendly lighting, Protect the Earth

Traditional fluorescent lamps contain mercury vapor, if broken mercury vapor will evaporate into the atmosphere. LED fluorescent do not use mercury, and LED products not containing lead, has protective effects on the environment. LED fluorescent recognized the green lighting of the twenty-first century.

2, efficient conversion to reduce the fever

Traditional lamps will produce large amounts of heat, LED lighting is energy all is converted to light, will not cause waste of energy. And documents, clothes will not fade phenomenon.

3, quiet and comfortable, no noise

LED lighting does not produce noise, the occasion for the use of sophisticated electronic equipment for a good choice. Suitable for the library, the office and the like occasions.

4, soft light, protect your eyes

Traditional fluorescent lamp use is alternating current, so per second will produce 100-120 times the strobe. LED lamps, AC power directly converted to DC, and will not produce flicker, eye protection.

5, no UV, no mosquito

LED lamps do not produce ultraviolet light, it will not be as traditional lamps, there are a lot of mosquitoes around the light source side. The room will become more clean and tidy.

6, the voltage is adjustable from 80V-245V

Traditional fluorescent lamp is lit by high-voltage rectifier release, can not be lit when the voltage drops. LED lamps can be lit within a range of voltage, but also adjust the brightness.

12, on the surrounding environment will not be affected. Ultraviolet and infrared, there is no hazardous materials, such as mercury, eye protection, and no noise.

13, resistance to vibration, easy to transport.

Laser originated in the great physicists Einstein , in 1916 Einstein proposed a new set of technical theory stimulated emission . This theory is that the atomic composition of the material, a different number of particles (electrons) are distributed in the different energy levels of particles in the high energy level by a photon excitation, jump from high energy level (transition) to the low energy level, then will radiate excitation light of the light of the same nature in a particular state, a low light to stimulate the phenomenon of a light. This is called by the stimulated emission of light amplification, referred to as laser. In 1958, the U.S. the scientists Xiaoluo and Townes found an amazing phenomenon: when they will be launched within the light bulb light rare earth crystal, the crystal molecules will be issued to bright, and always came together. of light. According to this phenomenon, they proposed the laser principle "material under its inherent molecular oscillation frequency energy incentives, this divergence of light – laser. Has published an important paper. Xiao Luo and Townes research was published, scientists from various countries have put forward a variety of experimental programs, but all without success. May 15, 1960, scientists Maiman of the Hughes Laboratory in California, USA announced a laser wavelength of 0.6943 micron, which is human history, the first laser beam, Maiman and thus become the world s first The laser introduction of practical scientists in the field. July 7, 1960, Maiman successfully developed the world s first laser, Maiman program, using a high-strength flash tube to stimulate the chromium atoms in the ruby ??crystal, resulting in a considerable concentration of the thin red beam of light when it fired at a certain point, which allows it to reach even higher than the sun s surface temperature. H.Γ. Basov, Soviet scientists in 1960 invented the semiconductor laser. The structure of the semiconductor laser is usually from the P layer, N and the formation of double-heterostructure active layers. Its features are: small size, high coupling efficiency, fast response, wavelength and the size and fiber size adaptation can be directly modulated coherence

New light as an energy saving, long life and environmentally friendly, the respondents experts and enterprises are certainly the prospects for the development of LED home lighting, consumers should be carefully selected.

A lighting companies, a lot of LED home lighting products produced by the LED semiconductor companies, these companies lack of lighting the accumulation of knowledge, LED technology alone produced product quality uneven. In addition, the LED chip replacement soon, the manufacturer often only the life of the LED chip suppliers marked on the packaging. In fact, the life of the LED lights is not the same as in the life of the LED chip.

Chang Yi pointed out that the current national safety standards for lighting, but no performance standards, while at the factory before the initiative to conduct performance testing and quality certification of manufacturers are not many, this will inevitably lead to the market price of the poor, good and bad quality products. The same time, manufacturers, products, spread big-to-peer situation has also led consumers to choose a loss.

1 Introduction.
The reducer is indispensable to industrial production, machinery and equipment, its performance and service life, has a direct impact on production capacity and economic efficiency, especially in the use and maintenance of mine reducer is very important.
Mine most of the operation the use of mechanical equipment can not be separated reducer, reducer equipment operation which is one component can not be underestimated, under the central role of the device, but it is a problem, it will cause the entire production system discontinued. will bring a range of workload, affecting the production, affecting the efficiency. Reducer on the exhaust valve is often overlooked components. But I do not know that it is very heavy parts of the reducer. It is directly related to the life of the reducer.
Here in the production of how seriously the exhaust valve on the reducer On the personal views.
2 analysis.
2.1 reducer.
Mechanical transmission can not be separated from the grease, grease it played the role of lubrication, cooling, mechanical high-speed rotation and long-term use, oil by continuous extrusion, when the oil temperature is gradually increased, resulting in a gas also the formation of a pressure. If there is no exhaust valve, the oil temperature will be a sharp rise in deceleration cabinets, pressure will gradually increase, to form a pressure. Pressure and temperature release is not out for power, it will in the cabinets of various parts, which parts to withstand the pressure in the case of action and reaction, which parts will be the role of pressure The first destruction, and finally the whole reducer various types of accidents.
2.2 oil seal.
Oil seal only plays a role in sealing the reducer which can work under pressure, working temperature below 80 ℃. Oil seal is not exposed to a supporting role, among other parts are not subject to any force. Reducer cabinets temperature rise conditions, the pressure increases, the first to be destroyed should be the oil seal oil seal oil seal pressure, low temperature coupled with the drive in itself has also been the role of friction, the effect of temperature.
2.3 Bearings.
The bearing temperature should be below 65 ℃, the normal operating temperature, the working temperature exceeds 65 ° C, was required to stop operation, and to take measures to cool. The deceleration cabinets temperature can not be released in the role of the exhaust valve, reducer cabinets temperature gradually increases, the working temperature exceeds 65 ° C if not taken measures to cool down, then the bearings will produce the Penghu expansion, with the temperature rise high, bearing balls and inner and outer rings Peng inflation, then the bearing balls and inner, outer gap is getting smaller and smaller, when the gap reached the limits of the bearing balls and inner and outer rings, bearings are not able to freely rotate when talking to all of us \"research bearing after the bearing is damaged iron will cause the gear to fight tooth, more serious, it will result in many accidents. Have serious consequences for the safe production.
2.4 gears.
Modulus gear in the transmission, under the external load force, which not only do power, but also to pass a law-abiding torque, work and the need for lubrication, and need more cooling, lubrication between teeth and teeth with a layer of mucous membranes, by force, resulting in temperature the fastest, highest part of the heat is passed to the grease, part of the heat transfer to give the meshing parts, cooling parts with grease, but the less the heat, warming fast , so gradually increased the temperature of the grease and gear, the gear is not only affected by temperature, but also by the impact of fatigue, changes in the internal organization of the gear, affect its service life.
In addition, the gear gap is more important, there are strict standards in the design, adjustment of the gap stringent requirements, if, in the adjustment of the gap amounted to less than the requirements, it will affect the service life of the gear motor. Usually we reducer shaft gear to fight tooth axis out in the field, mounted on a shaft tooth gap undetectable, although to solve a pressing need, but leave the troubles will be a continuous fight tooth. In this case, you must replace the entire reducer replaced reducer returned to the factory overhaul, factory-axis arc gear there are strict rules must be paired with the replacement (in the processing of pairs of grinding).
Our leaders at all levels and the use of the unit should not overlook the use of the exhaust valve on the reducer to attach great importance. Daily work to be done on the exhaust valve in each class will be seized, especially drivers, identify problems in time to the formation of a work. High oil temperature or the exhaust valve failure and into the report and take appropriate measures to cool down after the production, to avoid the occurrence of accidents. Some of the views and opinions are not necessarily correct, but also need further research in practice, to make it more perfect.

In the context of increasing scarcity of our natural resources and oil resources, the use of waste plastic and waste wood production and wood-plastic composite materials and processing technology has aroused great concern of participants.
    Waste of resources is also a resources
    Plastics in the production and life, with economic development more widely, white pollution caused due to improper handling of plastic waste has become a major environmental problem. The figures show that in the municipal solid waste, plastic waste has accounted for 25% to 35% of the total garbage. In China, the urban population annually produced $ 2.4 million to 2.8 million tons of waste plastics has become a serious burden on the sanitation department. If you can waste plastics effectively utilized, will be environmental protection and economic development have an enormous role in promoting.
    Wood shortage problems become increasingly serious as the economic development. Production and improved living standards, in the past been used for firewood wood processing waste, such as sawdust, wood shavings, scrap materials, as well as a large number of crop fibers such as straw, rice bran, husk, etc. is a serious waste and the environment devastating impact. According to statistics, China s annual timber processing the remaining waste wood flour amounted to millions of tons of other natural fibers such as rice bran yield thousands of tons of these resources, such as the effective development and utilization of considerable value.
    Waste plastic regeneration opportunities
    wood plastic composite materials will processed waste plastic and waste wood, including sawdust, twigs, wood, rice husk, crop straw, peanut shells to a certain percentage, add a specially designed additives, made of structural profiles after high temperature and high pressure processing, belonging to Basic industrial raw materials. It can be directly extruded profiles and then assembled into products such as pallets or crates. This new wood-plastic composite material with good mechanical properties, cheap, easy processing, insect resistance, resistance to corrosion, recyclable and features. 98% of the raw material of wood-plastic composite materials for the waste materials can be made into a variety of cross-section shape and size of products, and use a simple repair, sawing, planing, nailing, not only retains the advantages of wood processing performance, but also overcome the disadvantage of wood is not durable fear of infestation. The wood-plastic composite material is an excellent, economic and environmentally friendly new materials, can replace the outgoing shipments of wooden packaging materials and bedding materials also can be used for the decay of the chemical industry shed, decorative panels, flooring, channel, Taiwan frame and casting models, machine covers, water pump shell, electrical materials.
    Circular economy of a new bright spot
    Insiders pointed out that, with the emphasis on improvement in the level of environmental resources, waste recycling and comprehensive utilization of resources as the core loop model of economic development has become the trend of world economic development. China is a country with a large population, limited natural resources per capita, much lower than in Western countries. Vigorously develop the resource recycling technology will be economic development and environmental sustainability have a profound impact. The use of waste plastic and wood fiber production of wood plastic composites products is adapted to the requirements of good project.
    Produced annually by all kinds of waste plastic and wood fiber waste in the country, a considerable number. However, due to the domestic market still in its infancy, wood products in the domestic market, there is no large scale. The Chinese market and the North American market, the growth of wood-plastic composite materials and finished goods, there is a considerable space, the expected domestic wood-plastic composites market in recent years, production will be more than one million tons, the output value of over 1 billion yuan, and the formation of new wood-plastic composite product system. Beijing 2008 Olympic stadiums and supporting facilities, such as wood-plastic composites as building materials, on the one hand, would greatly reduce the construction costs, on the other hand will be more prominent Green Olympics, Scientific Olympics theme.
