LED Lighting Facts
   
What is COB?

COB (Chips on Board) , is a new technology of LED packaging for LED light engine. Multi LED chips are packaged together as one lighting module. When it light up, it looks like a lighting panel.

Why COB ?
Background
   

LED(light emitting diode) is new technology with advantage of saving energy and very long lifespan. But all LED light source cannot be faultless especially SMD, HP, flux LED etc. Compare to traditional lighting such as fluorescent lamp, as it is super bright in a small size, it cause uncomfortable glare.

The greatest power densities on the smallest space are often the basis for unique selling points of various products on the market. These criteria can be realized by the ( Chip on Board ) COB LEDs technology.

Direct contacting of the semiconductors (LEDs) on PCBs allows for optimal thermal management, high packaging density and thus long-lasting and high-performance COB LED modules.

How COB LED Light source works
   

COB LED is multi chips packaged, it can 10 times more increase lighting area, so it avoid uncomfortable glare by the maximum extent. Lights spot use small size of chips to make COB LED package.By now, for small size chip, ?some famous LED chip manufacturer can reach 249lm/watt @ 20mA. But big size LED chip can only reach 161lm/watt @350mA. The light efficacy decrease when chip size is bigger. Also when LED driver increase current to LED, the light efficacy per watt is even low.

COB Advantage
   

COB, (Chips on Board) , multi LED chips are packaged together as one lighting module. COB LEDs have great advantage of thermal resistance, larger cooling area, better lighting effect and high light efficacy.

 
What is New ???
   
(Multi Cups/Chip on Board) MCOB LED

The Next Generation of LED, is without doubt, Multi or integrated Chip known as MCOB (Multi Chip On Board) or MCCOB(multiple chips and cups on board).This new LED lighting technology comprises of many small-chips integrated into one large single chip.

These are used widely now in floodlights and High bay lights. They are cheaper to assemble than multiple single chips and so make products like high bay and floodlight, much more affordable than multiple one worth reading what chips. The more well-known companies working on this technology are Bridgelux (USA) and Edison and Epistar (Taiwan). As with all LED products however, the drivers and thermal management are the key to LED product longevity

CREE and a few others make integrated chips, but are currently prohibitively expensive. MCOB is also found in LED bulbs and LED tubes, however compared to SMD surface mounted diode technology, MCOB technology is still in its infancy. Watch for this exciting new technology new ultra efficient high output LED lighting.
