④ LED life ≥ 50000h (light failure 10%, 85 ° C junction temperature). ⑤ LED lamps 6000 hours, light failure less than 1%. ⑥ color rendering index: Ra> 90. ⑦ Color temperature: 4000K ± 275K. Third, the lithium iron phosphate battery 600WAH lithium iron phosphate battery 1. No pollution. Lithium iron phosphate battery does not exist toxic substances, it is called "green battery", by the state key support, and lead acid battery is the main component of lead and sulfuric acid, which is also the main solution of sulfuric acid and lead compounds. 2. Discharge depth, energy density (relative to lead-acid batteries) long-term rational use can be to 95%. 3. Cycle life, the number of cycles up to 3000-3500 times. To maintain 70% capacity, the use of up to 6-10 years. 4. Allow a wide operating temperature range, the battery can work between -30 ℃ ~ 50 ℃, -30 ℃ environment can discharge more than 90%. 5. Charging speed, 2C charge within 30 minutes to make the battery filled with 95%, starting current up to 2C. Five, small size, light weight: the product design can be lightweight, the volume is the same capacity lead-acid battery 2/3, but also smaller than the size of nickel-hydrogen batteries; weight is the same capacity lead-acid battery 1/3, nickel-metal hydride batteries 2/3 or so; 6, the battery voltage is high, the stability of the discharge platform: 3.2V, less series, the battery pack high reliability; high reliability battery pack can be used for high current high power charge and discharge high rate discharge characteristics: 10C Charge and discharge efficiency of 98% or more, capacity retention rate of 95% or more, can achieve 10C discharge rate. Fourth, the solar charge and discharge controller 1, Specifications Model: light control + dual time controller (). 2, technical requirements: ① solar charge and discharge controller using a single chip to achieve the protection of the battery. The basic functions must have overcharge protection, over discharge protection, light control, time control, anti-reverse, charge trickle protection, undervoltage protection, overvoltage protection, short circuit protection, waterproof protection. ② to ensure that the controller 24 hours without interruption, their own power consumption is less than 2% of rated power. ③ to choose the high efficiency of the controller (imported components), should have the ability to automatically track the maximum power output PVPT12V / 24V intelligent identification function. ④ products meet national standards, and through quality certification, the service life of more than 15 years. 5, light pole 1, specifications Model: pole height of 6 meters, the material for the Q235 carbon steel, hot dip galvanized inside and outside the surface should be anti-corrosion treatment. 2, technical requirements: ① light pole with double round arm light pole, height 6 meters, diameter 90mm. ② pole material for the Q235 carbon steel, should be hot-dip galvanized inside and outside the surface of anti-corrosion treatment, in line with GB / T13912-92 standard, galvanized surface should be smooth and beautiful. Provide galvanized test report. Galvanized thickness of not less than 85μm. ③ light pole wall thickness ≥ 5mm, light pole chassis thickness of 30mm. ④ weld surface without cracks, stomata, undercut, not full of defects.
