2, better appearance on overall structure, it has the aesthetic property of existing street lamp concurrently, this street lamp can also be made the beautiful scenery line in city except the function that the illumination brightening is arranged, reach and beautify the environment, the brightening road effect;

3, the utility model is that heat, electricity separate in design, promptly inserts power supply by the external world; Heat-conducting plate and heat radiation cylinder are arranged again separately, its heat-transfer rate is fast, area of dissipation is big, thermal resistance is few, and weight is low weight simultaneously, the lamp body area is little, wind loading rating is strong, because electricity is with heat separately more secure to the appliance life of lamp;

4, described outer cover adopts engineering level PC material, good weatherability, and light transmittance 〉=87%, shock resistance, ageing-resistant, promptly attractive in appearance practical again;

5, the good wing luminous intensity distribution of bat, span is bigger, and the light uniformity is better! The optics reflector of distinctive two kinds of shapes has been installed for this reason, its reflectivity 〉=97%, the light extraction efficiency of whole light fixture 〉=97%;

6, adjustable angle, this street lamp not only have the adjustable angle device of horizontal level, and it can level-off, also can adjusting angle, be convenient to work high above the ground, and simple to operate, reliable;

7, its colour rendering is good, and Ra 〉=87% is that the ideal of outdoor lighting is selected;

8, owing to the heat radiation thin slice that on the surrounded surface of cylinder, also is provided with a plurality of sheets,, in light weight so its area of dissipation is big.
