Item Lighting components technical requirements scoring standard Remarks 1 Housing die-casting aluminum molding appearance, polyester powder-spraying surface treatment, corrosion resistance, temperature difference resistance 3 points Provide material documents 2 Reflectors have undergone scientific optical design, hydroformed electroplated aluminum reflectors , The use of more than 85% reflective aluminum, if necessary, to reach 95%. The surface is anodized, the reflector is optically designed, and the bottom is raised to avoid direct light to the light source and prolong the life of the light source by 5 minutes. Provide relevant documents and physical objects. The glass cover is a curved surface with optical refraction pattern and half-cut light type, which can better improve optical efficiency and reduce glare. More than 85%, the lamps have scientific, optical overall design and manufacturing process, and the lamp manufacturers with higher luminous efficiency are preferred 5 points Ditto 6 Light distribution The light distribution of lamps must adopt NEMA (National Engineering Manufacturing Association) multi-level professional road light distribution standard 10 Ditto 7 Seismic grade Anti-seismic grade reaches 3G 3 Ditto 8 Structure Lighting structure design is scientific, no tools are required to open, easy to maintain and replace the light source 3 Ditto 9 The light source adopts high-quality light source, 600W high pressure sodium lamp reaches 90,000 initial lumens, and the service life is more than 20,000 hours. The 400W high pressure sodium lamp reaches 56,500 initial lumens, the service life is more than 20,000 hours, the 250W high pressure sodium lamp reaches 33,000 lumens, and the service life is more than 20,000 hours. 2 points as above 11 The ballast adopts electronic ballasts 10 points as above 12 Illuminance analysis According to the lighting arrangement in the design scheme, the relevant technical requirements for road lighting are: the average brightness is 2cd/m2, the average illuminance is 35lux, and the uniformity u0u003d 0.4, u1u003d0.7, the glare control level is 6G, and the threshold increment TI (%) is 10. The bidder is required to have special illuminance calculation software for verification and provide a detailed illuminance analysis report (the maintenance factor is recommended to be calculated as 0.8) 5 points Ditto 13 The appearance of lamps and lanterns has smooth lines, beautiful appearance 2 points Ditto 14 The light effect of the bid lamps and lanterns, in the case of meeting the national standards, the average illuminance, uniformity, glare value comparison 5 points The same as above 15 The bid lamps and lanterns for energy-saving use, in meeting the national standards In the standard case, for the comparison of power loss, the comparison of the number of lamps used is 5 points as above 16 The cost of using the bid lamps is the same as the comparison of the investment in the construction cost of the project 5 points as above
