I. Overview Ceiling:? Apply to rail cars, locomotives, rail cars, subway cars, cable trench, tunnel, subway platforms, corridors, airports around the world and other lighting. Applications that require waterproof, shockproof lighting situations. Second, the performance characteristics Ceiling: Create a safe working environment wide operating voltage, to ensure normal and stable voltage fluctuations in the harsh lighting environments. LED light source, to ensure that lighting instant cold start and hot start. Integrated aluminum alloy structure, lightweight, impact resistance, and can be reliable and stable work under vibration and shock environments. Optical design and high-quality anti-glare design, effectively avoid visual fatigue staff. High-efficiency high-power LED light source, precise optical design, with 99.99% high purity aluminum reflector cup and light transmittance of up to 93% of the imported PC transparent parts, lighting efficiency up to 79%, higher than the industry average of 40%. ??? Advanced and reasonable circuit design, with high-quality components, electrical efficiency up to 90%, higher than the industry average of more than 6%. ?? Effective and efficient light source + + efficient circuit, so CGT9121 / ONLED ceiling than the industry standard 50% energy. ??? Seven consecutive years of uninterrupted work without replacing the light source is a fluorescent lamp life 10 times. ??? Shell corrosion grade WF2, to ensure that lighting does not corrode in the harsh environment, does not rust. ??? Accordance with the national standard quality control system, through rigorous reliability, aging test, lower lighting failure rate. Third, Ceiling technical parameters Rated voltage AC / DC15-48V 50HZ AC / DC85-260V 50HZ LED light source power 4 × 3W Housing protection IP65 Insulation Class WF2 Dimensions 350 × 135 × 55mm total weight of 1.2kg Fourth, quality assurance Ceiling This product is in strict accordance with ISO9001: 2008 international quality management system standards for quality control to ensure product quality is higher than the national standard, fully meet the design requirements, the product of 7 years warranty (lamp warranty for one year), within seven years from the date of purchase, product under normal use of any quality problems, borne by the company.
