I. Introduction: 1. Environmental protection, energy conservation, lighting normal life: more than 30,000 hours. 2 at the same brightness of the front embankment, 80WLED mining than high pressure sodium lamps saving 60%. Two application areas: 1 applicable to workshop, factory, warehouse, highway toll stations, gas stations, supermarkets, exhibition halls, stadiums and other places need lighting. Third, the product features: 1. Adopt single high-power LED 80W as the light source, using a unique multi-chip integrated single source design, selection of imported high brightness semiconductor chips with high thermal conductivity, low luminous decay, pure light color and no ghosting. 2 unique heat sink design, the perfect combination with the electrical box, the effective diffusion of heat conduction, thereby reducing the temperature of the lamp body, effectively ensuring the light source and power of life. 3 radiating surface anodic oxidation treatment, compact appearance. 4 green pollution-free, no lead, mercury and other pollution elements, no environmental pollution. 5 color is good, the physical color rendering more real, a variety of light colors optional, to meet the needs of different environments, eliminating the traditional lamp color temperature is high or low depressed mood, so visual comfort, improve people's working efficiency. 6 using constant current control for wide voltage, power generation to overcome due to the ballast, noise pollution and unstable light caused by work to avoid causing irritation, fatigue to the eyes. 7 good decorative effect, using a special surface treatment process, the appearance of new, simple to install, easy removal, a wide range. Fourth, product specifications and parameters Product Dimensions: Φ160 * 70MM Voltage: AC110-240 / 50-60Hz Power: 1 * 30W Lumen: 2400-2700LM protection: IP65 CRI: ≥75Ra ★ 1 maintenance and repair maintenance and repair instructions before Make sure that you have power outages. Mining lamp glass regularly cleaned to maintain good light fixtures. 3 regularly dust shell and radiator mining lamps were cleaned to maintain good heat dissipation. 4 Be careful not to water or corrosive cleaning solution, preferably with a dry cloth. 5 When replacing the power supply, you can directly open the back cover with a screwdriver, remove the power supply, AC power wiring in accordance with the three-core wire corresponding red "L" on the power supply, blue corresponds to "N" on the power supply, yellow-green or yellow corresponds " ", DC power cord of red or white lines correspond to the power of positive black line corresponds to the negative power supply, do not pay attention to the positive and negative reversed. ★ warranty, after-sales service for all of the company's product is built with two years warranty constant current power supply, LED light source warranty for two years. Under normal conditions of use, quality assurance is based on preservation, installation, use and maintenance; due to improper installation, use, abuse of the Product, and caused damage to the product, do not fall within the scope of this guarantee; quality warranty quality problems during the warranty period, the company will choose to repair, replacement (parts) or replace new products and other methods to solve them; exceed the quality warranty period materials, labor costs will be charged appropriately.
