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 bulb.
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.
The cob contains individual led lights that can vary from 80 to 108 lights.
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.
A 40w cob led incandescent bulb replacement will put out 4000 lumens and has a life expectancy of 35 000 hours.
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.

Numerous channels for modifications are needed to produce the color changing outcome.
This observation is the resultant effect of the one circuit and two contact design of this system.
Led corn bulbs are named for their appearance as they resemble the corn on the cob.
Gary mcvay gary a 300w incandescent puts out 3500 lumens and has a life expectancy of about 5000 hours.
3 chips a cob led light source can have multiple chips dozens or even hundreds on the same printed circuit board pcb.
Led lights come in a variety of models.
The cob vs smd led lights differ in terms of their features and semiconductors.
Multiple leds minuscule in size are wired and packaged together into a single ceramic or copper board so that they function as a sole light source.
This single circuit design.
Similar to smd cob chips too have multiple diodes on the same surface.

They have lines of square light diodes on all sides of their tube.
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.
