7w high qulity cob indoor led ceiling lamp

2.1   Light source

      High Power SMD3030 LED. Low thermal resistance，pure color with consistent color  temperature，High lighting efficiency,

2.2、 Radiator

With AL6063High thermal conductivity aluminum,thermal conductivity >200W/m.k;

2.3、Shell

Shell material is AL1070 pure aluminum with high precision lathe processing，sand blasting,surface drawing,high polished,anodizing for your choose;

2.3、Light distribution

Lens with professional engineer design, material by high transmission PMMA，exact small angle of light and uniformity are important in accent lighting effect，surface of lens with quadrille and glass bead design make light be soft ，induce halation and glare;

2.3、Power supply

The external power supply，isolated with lamps ， improve lifespan of power supply and lamps，constant current drive ，Current range of small, high conversion efficiency，luminous efficiency is much better ;

Installation

4.1 According to the shown below，open one suitable mounting holes on ceiling，ensure that the minimum space is enough and don't affect the house beam, the safety of pipes and cables and other facilities ;

4.2 Make constant current source's negative and anode output lines corresponding to the LED lamp's negative and anode input lines，input parts connect high voltage（as shown in the figure）
