LED is the English light emitting diode (light emitting diode) acronym, and its basic structure is an electroluminescent semiconductor material chip, with silver or white glue curing glue to the frame, then with silver or gold thread connecting the chip and the circuit board and then sealed with epoxy resin around, play a role in protecting the inner core wire, and finally mount enclosure, so the seismic performance LED lamps. LED Features Benefits: intrinsic characteristics of LED determines that it is the ideal light source to replace conventional light sources, it has a wide range of uses. Small size LED is basically a small chip is encapsulated in epoxy, so it is very small, very light. Low power consumption LED power consumption is very low, in general LED's operating voltage is 2-3.6V. Operating current is 0.02-0.03A. That is to say: it consumes than 0.1W. Long life at the right current and voltage, LED life of up to 100,000 hours of high brightness, low-calorie green LED is made from non-toxic materials, unlike fluorescent lamps containing mercury can cause pollution, while LED can also be recycled use. Durable LED is completely encapsulated in epoxy resin inside than light bulbs and fluorescent tubes are solid. Light body and no loose parts, these features make the LED can be said that are not easily damaged. LED lights biggest advantage is energy saving. Light-emitting efficiency of 100 lumens / watt, ordinary incandescent lamp only 40 lumens / watt, energy-saving lamps also at 70 lm / W hovering around. Therefore, the same wattage, LED light effect will be much brighter than incandescent and energy-saving lamps. 1 watt LED lamp brightness equivalent to 2 watts of energy-saving lamps 5 watt power LED lamp 1000 hours 5 degrees, LED lamp life up to 50,000 hours, LED lamp no radiation. Chunk strategy is to make sense of the unit's members scattered components. From the perspective of information processing chunk of information is people organize or re-encoding. It can be said, in order to increase the capacity of reading and improve reading instruction information processing efficiency, the chunk is the key. According to the degree of material significance, the chunk can be divided into two distinct operations: the meaning is not strong, difficult to classify the material, and strive to create a link from the material out to give them a certain sense; the significance of sex strong material, and strive to grasp the deeper meaning behind the literal sense, deep level of processing. Although the contents of the memory will never be filled brain, but many psychological experiments show: In the short-term memory activity, the brain typically receives not more than seven units of quantity. American psychologist Miller raised short-term memory capacity is generally 7, and between 5-9 fluctuation ⑷, ie limited short-term memory capacity. However, short-term memory capacity and is very strange, it is a group of block units. The chunk can be a word, it can be words, phrases, even sentences. What is a chunk? It refers to a number of smaller units jointly made familiar processing units larger units, but also refers to a constituent unit. Visualize learner understand and grasp the material on the basis of law, the basic characteristics of the content, based on the meaningful material memorizing material into charts, drawings material, or material organization is an associate meaningless chunks. According to the relationship between the content of the material, figurative block diagram similar classification can be divided into charts, comparison charts classify, categorize subordinate charts. In addition to a chart to illustrate the intrinsic link type material, can also be presented graphically using structural relationships hidden within the material, such as the relationship diagram, flow chart, so that the material to visualize, and promote the overall grasp and remember. Mr Wei grade teacher designed "Knowledge Tree" is a relational icon to visualize classified trivial language knowledge. Chunk between certain materials are not necessarily meaningful contact, given that we must rely on mechanical homophonic law meaningless material with a certain sense, or the use of non-contact method of Lenovo material items given to human contact, thereby forming the image . For example, concerning the name of Lu Xun's essays, many students often are not allowed to remember, remember missing, some teachers use the formulas in the form of the name of Lu Xun's essays regrouping, into easy to read and easy to remember chunks: "hot air grave canopy only; three busy north-south set disloyalty; lace love affair pseudo-freedoms; two series and set the outer set of dielectric; outer set of gleaning and Supplement;. translations of ancient prefaces and postscripts set "Thus, the present name of the sixteen essays through processing into six a linked block, students can easily remember the names of these essays. For products: Please inform product name, material (such as ABS, PP, PC, PA6, PA66, PEEK, PPS) use (electronic products, daily necessities, stationery, gifts), use of the environment and requirements (if required high temperature, corrosion, normal operating temperature is in contact with oil or water, whether it is for outdoor use, there is no resistance or low temperature UV-resistant requirements, the availability of ROHS or FDA requirements) file format: Please provide 2D and 3D file formats, 2D file formats: pdf, dwg, etc., dwg format please provide 2004 versions; 3D file formats: prt, stp, igs, sldprt, x_t etc. for format compatibility's sake, please provide stp or x_t format; proofing fee: If you need to verify before mold Product appearance and assembly complex, need to make a hand model, hand model for a surcharge, the specific hand MILL quote; mold price: mold price and product mix, size, the number of cavities, production process, mold core steel-related, We need to follow specific products and customer requirements accounting, the default technology for the production or use Dragon Long-teng of standard mold, mold core within the LKM738H use Dragon Steel, all top marks and holes are in the sub-thread cutting slider layering, wearable pieces, block the use of high-SKD61 hard materials, materials are all thimble SKD61; mold Delivery: mold production cycle is generally between 20 and 40 days, depending on the degree of product complexity may be hard mold surface do sticks, polished mirror, etc. need to increase 5-10 days. Ordinary plastic material products, the plant owned by the tryout material, high-performance materials such as PPS, PARA, PEEK, PPSU, etc. tryout material provided by the customer; mold of payment: the date of signing of the contract from 50% advance within 3 days From start to take effect and duration of the contract, submit to pay 30% of the payment within 3 days after the appearance of the first test qualified products, customers pay the remaining 20% ??of the payment confirmation after the final payment of qualified products, advances arrive the day, issued a full factory invoice . Other: before mold making factory presented an analysis before the product is a model, as a result of the production on the reason you need to change the structure or design of the product, you need to obtain the customer's consent in advance, in the mold making process, if the customer needs to change the product mix, the This brings additional costs, by the customer burden, the duration be extended accordingly. As a result of the mold design or production reasons, can not be submitted to the customer samples tested, the factory has the responsibility to be modified within the agreed date, the date specified as not submitted samples tested, the factory will bear the corresponding liability;
