4.1 Lighting fixtures should be light and efficient. The efficiency of indoor-opening lamps is not less than 90%; the efficiency of lamps with covered lamps is not less than 90%.
4.2 The lighting fixtures have various mounting methods such as hanging pipes, ceilings, wall mounts, and risers. The bidders should meet the needs of the site. Lamps have electromagnetic compatibility, lightning protection, and isolation systems.
4.3 Three anti-lighting lamps for outdoor and workshop use shall be waterproof, dustproof and anticorrosive. The three defense lamps include: street lamps, outdoor spotlights, indoor spotlights, and lamps with three anti-words.
4.4 Requires CCC certification and provides certification inspection report, light source international CB certification.
4.6 General Requirements for LED Lamps
4.6.1 Maintenance-free energy-saving dustproof, waterproof, anti-corrosion LED lamp requirements:
4.6.1.1 Light Source
1) Light source type: imported Philips, Osram, CREE and equivalent light source, high luminous efficiency, long life, imported power supply, Meanwell, Moso, TSMC and equivalent constant current and constant voltage Power supply, wide voltage AC100 ~ 240V range, to ensure that the drive power supply is not subject to changes in the power supply voltage to reduce the lamp power changes, with stability, anti-voltage fluctuations against electromagnetic interference.
2) Rated power greater than 150W, luminous efficiency up to 110Lm/W or more
3) Voltage range: AC 85V-265V, power output deviation is not more than 1%.
4)Color temperature: 4500K-6500K
5) High color rendering: Ra>70
6) Working life: 2-5 million hours
7) The power factor is not less than 0.98
8) Light decline is not more than 8% within six years.
Deforming Superalloy
Deforming superalloy refers to a class of superalloys that can be hot and cold deformed, have good mechanical properties, comprehensive strength and toughness, and have high oxidation resistance. The deformed superalloy produced by Seonjip is mainly used in fields of nuclear power, gas turbine, aircraft, aero engine, petrochemical industries and so on.
