What Is A Cob Led Light Bulb

A cob short for chip on board is an led packaging technology that describes mounting multiple led chips directly onto a substrate to form a single module.

What is a cob led light bulb. Led lights come in a variety of models. It is known that led lights have a longer lifespan than regular lights but with the cob led lights technology you can expect your light bulb to be even more durable and long lasting. Gary mcvay gary a 300w incandescent puts out 3500 lumens and has a life expectancy of about 5000 hours. They have lines of square light diodes on all sides of their tube.

An led lamp or led light bulb is an electric light for use in light fixtures that produces light using one or more light emitting diodes leds. This single circuit design. You can choose between smd vs cob types for example depending on your needs for energy efficiency and versatility. It might be a little bit expensive at the start since cob led lights require high initial investment but after a while you will be benefiting a lot from them.

The cob vs smd led lights differ in terms of their features and semiconductors. 3 chips a cob led light source can have multiple chips dozens or even hundreds on the same printed circuit board pcb. For example a 500 lumen cob led array can be many times smaller and consume substantially less energy than a 500 lumen smd or dip led array. This observation is the resultant effect of the one circuit and two contact design of this system.

Set your store to see local availability add to cart. Led corn bulbs are named for their appearance as they resemble the corn on the cob. Maximus 500 watt equivalent e39 corn cob led light bulb model mcc1216k50mpwc1 80 97 80 97. Led lamps have a lifespan many times longer than equivalent incandescent lamps and are significantly more efficient than most fluorescent lamps with some manufacturers cree and others claiming led chips with a luminous efficacy of up to 303 lumens.

The other big advantage of using cob led technology lies in the fact that cob devices have only 1 circuit and 2 contacts for the entire chip regardless of the number of diodes. On the contrary cob led light is not suitable for producing lights or bulbs that are color changing. Hy lite 54w omni cob led lamp 250w hid equiv 5000k 7560 lumens ballast bypass 120 277v e39 base ip 65 ul dlc listed model hl oc 54w e39 50k. The cob contains individual led lights that can vary from 80 to 108 lights.

Linked to the 3528. Start comparing cob vs smd led lights or before you look at the difference between led light cob and smd. But the difference among led light cob and smd is that cob leds have more diodes. Similar to smd cob chips too have multiple diodes on the same surface.

A 40w cob led incandescent bulb replacement will put out 4000 lumens and has a life expectancy of 35 000 hours.
