What is COB LED ?

COB
COB, (Chips on Board), multi- chip package together as a LED lighting module . When it lights up , they look like a luminous surface . .

Why use COB technology ?
LED (light emitting diode light-emitting diode ) is a new generation light source, with energy saving features , but not perfect. Due to its high luminous intensity per unit area , so bring serious glare compared to traditional light sources . When you need high-wattage light source , you need to install multiple LED together without taking a mist or fog lens filter , there will be serious zebra while using mist filter or mist lens will bring no small loss of light .

How COB LED light work

Century spot has LED MCOB technology intellectual property rights, an advocate LED surface light source . Century spot clusters with small size chip packaging technology

Clusters of small size chip package increased the number of times the light-emitting area , the maximum to avoid the glare

LED light efficiency increases as the chip size is reduced . Latest achievements so far the world's major LED 's luminous efficiency has small chips can do 249lm/watt @ 20mA, while the large-size chip only do 161lm/watt @ 350mA. With the increase in drive current , the luminous efficiency will be reduced.

Clusters of small size chip LED package has become a trend in packaging technology . Future LED lighting and backlighting, surface-emitting light source will occupy at least half.
