item number chy-tech parts of die-casting aluminum molding technology required criteria review 1 shell appearance, polyester powder coating surface treatment, corrosion resistance, heat resistance 3 points to provide important file 2 reflectors after science of optical design, hydraulic forming of electroplating aluminum reflector by more than 85% of the reflective aluminum, if necessary, can be made of 95% of the reflection of aluminum. Surface anodic oxidation treatment, mirror through optical design, at the bottom of the trunk, avoid direct light source, prolong the service life of the light source. 5 points and provide the relevant documents and data 3 glass high temperature resistant, impact resistant borosilicate optical glass can withstand the large temperature difference. The glass is curved, with optical refracted ray and half light type, can better improve the optical efficiency and reduce glare. 2 points as above four protection level of IP65, lamps and lanterns has superior waterproof dustproof performance 2 points as above 5 light effect of the lamp luminous efficiency of 85% or higher. Lamps and lanterns has scientific comprehensive optical design and manufacturing process. High luminous efficiency of lamps and lanterns manufacturer is preferred. 5 points up six distribution of lamps and lanterns with light must use NEMA ( The national engineering association) Multistage professional road light distribution standard 10 points up seven earthquake magnitude earthquake resistant level 3 g3 points up eight lamps and lanterns of the structure design of scientific structure, don't need a tool to open, easy to maintain and replace the light source. 3 points up nine light source adopts high quality light source, 600 w high pressure sodium lamp 90000 initial lumens, the service life of more than 20000 hours, 400 w high pressure sodium lamp 56500 initial lumens, the service life of more than 20000 hours, 250 w high pressure sodium lamp 33000 lumens, the service life of more than 20000 hours. Three points as above 10 auxiliary electric lamps and lanterns is equipped with high quality electrical products, power factor is 0. 85, the service life of more than 10 years. Two points up 11 12 lighting ballasts electronic ballasts 10 points as above analysis method according to the design of light distribution, related technical requirements for road lighting: the average brightness of 2 CD/m2, the average intensity of illumination of 35 lux, evenness u0 = 0. 4,u1 = 0。 7, glare control level is 6 g, threshold value increment TI ( %) To 10. Require bidders to have special illumination calculation software to verify and provide a detailed illumination analysis report ( Recommended maintenance coefficient according to 0. 8) 5 points up 13 lamp appearance beautiful appearance, smooth lines, beautiful shape 2 points up 14 tender light effect under the condition of meet the national standard of the average intensity of illumination lamps and lanterns, evenness and glare value comparison. 5 points up 15 use tender light energy saving, in the case of meet the national standard, power consumption and the use of the number of lights. 5 points up 16 cost use bidding for engineering cost investment of the lamp is above 5 points
