路灯设计毕业设计英文摘要

1、Topic selection significance Now the most domestic lighting lamp is very similar, modelling is boring, the function is simple. Street lamps that our life is actually part of the landscape, it besides illume effect outside, still can help us solve some of the problems in life, such as the alarm funct

2、ions, road signs function and so on. My topic is in shape improved design and do improvement on the lighting system, change the usual in our life the appearance of the street lamp lighting and lighting, can add alarm clock function, etc. Help people in the face of a difficult time get help, and can

3、be a relatively short time made the place. The light with the problems changing the changes in temperature, give people warm feeling. Beautiful, and use of the street lamp can beautify our city, park, school, the courtyard environment, the design a practical strong street lamp products, make the pro

4、duct better service for the peoples life. Research situation overview Now the lamps of the production use at home and abroad are familiar, are generally use aluminum alloy and low carbon steel, the LED lighting technology. 1, the lamp pole material selection Shanghai baosteel produces high grade Q23

5、5A type low carbon steel, steel silicon content is higher than 0.04%, and the large bending machine a bending forming, straightness error less than 0.05%, the wind light pole the ability to 36.9 m/s 11 class above design, resistance to the earthquake intensity for eight level. The lamp pole welding

6、way for automatic submerged arc welding connect, welding and reliable, smooth surface, no apparent porosity, welding tumor, bite edge welding defects, ultrasonic flaw detection test, the welding GBl1345 level standard requirements. 2, steel rod anticorrosive processing with internal and external hot

7、 galvanized, galvanized process after pickling, hot dip galvanized, washed, phosphating, passive process, galvanized layer surface is smooth and beautiful 3, pervious to light cover the surface high strength of toughened glass, resistance to high temperature 200 above, light transmittance high, impa

8、ct resistance. 4, reflector, toughened glass and lamp holder with adhesive sealing into one, in the bubble structure of change, with good seal performance, more than 250 high temperature resistant seals, seal degree of IP66. 5, the light body, light cover using aluminum alloy die-casting, surface of

9、 electrostatic pensu processing, with light structure corrosion. Lamps shell anticorrosion performance level; 2, reflector adopted high pure aluminum pressure molding, the anodic oxidation electrochemical polishing processing, has an optical stable performance, and the characteristics of high reflec

10、tivity. The main research contents Lighting lamp is our living environment has been an important part of, for our life brings a lot of convenience. Street lamps of our life as an important products, it has the important development research potential, but now the street lamp on modelling and functio

11、n has many the insufficient place, we can from lighting mode and appearance on begin. I main research now the city life to the needs of the street lamp lighting, and for existing street lamp modelling classification and analysis. Another: the solar energy lamp working principle different occasions L

12、ED lighting lamp technology and modelling requirements of the lamps in the existing classification and characteristics, and the defect existing street lamp lighting technology in the street lamp of the application of the production design trends for future lighting lamp understanding The study is us

13、ed to train of thought (method, the technical route and feasibility, etc) (1) to understand current situation and on-the-spot investigation: according to the survey, design and modelling. (2) security design for the premise, thorough research, humanity, and function diversity and practicability. (3)

14、 it is with the person this, product modeling design is given priority to function. Lighting lamp and function design, mould fabrication grass questionnaire research, the sketch modelling design scheme. See related literature, magazines and books. (4) from appearance and colour, and function and saf

15、ety these aspects to consider and design, according to the survey conception final feasible scheme. (5) field survey, in a survey of sanya for object, which park, school, lane, streets of existing between the lamps of the classification, analysis and investigation, collecting material information, s

16、trengthen my design. (6) key interviews, to manufacturer and technical personnel exchanges, to the requirements of the production technology and matters needing attention, the perfect design, avoid technology and manufacturing mistakes. (7) for a number of design scheme, making model of multiple sou

17、rces, let the light from the test. (8) screening program, experiment, test, to determine whether the design scheme Complete design model and final draft In order to meet the standard of city road lighting design, the traditional road lighting often take the power consumption of water cut more than 2

18、00 w bulb silver. In contrast, by 2009, the market light emitting diode (LED) optical efficiency has more than 100 lm/W, this means using LED light source for the street lamp, its power consumption will be greatly reduced. Because of the long life LED, do not contain mercury and the characteristics

19、of energy saving, using LED light source for the street lamp to replace the traditional LPS (low voltage sodium lamp) or MH (metal halide lamp) is a good choice. At present, the LED street light in the world each country was tested. In order to solve the energy shortage and greenhouse gas emissions,

20、 LED lamp in some places have already practical, including China, North America and Europe in some areas of the city and the government of a positive promotion. On the market of the factory is a LangBo LED most type (Lambertian distribution) distribution, the center light intensity is stronger, and

21、is symmetrical circular flare distribution, cannot be directly used for road lighting. In order to meet the city road lighting design standard, LED lamp needs a second optical design, in order to generate a rectangle, uniform distribution of flare, its light distribution curve in the shape of the wi

22、ng to bat. In addition, the stand or fall of optical design directly determine the efficiency of the street lamp LED, some LED street lamp with two lens design bad after some light in lens inside multiple reflections off or loss after is not worthy to effective area, some secondary lens flare shape and evenness though, but the efficiency of light is decreased nearly in half. Also, the stand or fall of optical design are also set a
