20W LED Down Light

Parameter: Model: CG-DL4-185N20W-170N Size: Φ185*96 Voltage: AC85-265V Material: Glass+Aluminum Beam Angle: 120° Power: 20W Life Span: 50000 hours Color Temperature: 2750-6000K Luminous Efficiency: >80 Application: Apply to hotel, various of selling places, shopping mall etc. Apply to office, conference room, exhibition hall,etc. Apply to living room, dinning room, kitchen, bedroom etc. Apply to airport, station, exhibition hall, library, hospital, school, factory and other public places. Special Advantages: Light source using COB(Chip On Board) direct encapsulation technology,this access to large-scale heat dissipation of module area. Facilitate the heat diverge from the white LED module to the LED lamp, This could suppress the temperature rises of the blue LED chips inside the module when the light source working., so it will remain luminous efficiency on higher state.Now the light efficacy can get up to 130LM/W. Compared with other encapsulation technologyes, COB technology has the following advantages: low price; save space;mature process. Important Technology Information: 1.Pure aluminum plus 30% heat dissipation compared to normal general housing of Aluminum Alloy Casting Die. 2.Streamline housing design, double heat spread area. 3.Appearance with anodized treatment, increase by 20% heat radiation, by contrast. 4. Circuit design. 1) Safety standard. A. Optocoupler isolation circuit design. B. Isolation coil transformers, non-inductive. C. According to CE safety standards EN61547 + EN60598, and UL safety standards UL1993,UL8750. D If the products is abnormal, it will not damage the human and property, protect user safe effectively. 2) EMC Standard A. According to European EMC standard EN55015, and the United States FCC standard Part 18. B. Effectively resist surrounding electromagnetic environment effects, and inhibit the proliferation of electromagnetic energy to the surrounding environment.
