What is a cob led bulb.

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. 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.

The cob vs smd led lights differ in terms of their features and semiconductors. Set your store to see local availability add to cart. You can choose between smd vs cob types for example depending on your needs for energy efficiency and versatility. 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.

Similar to smd cob chips too have multiple diodes on the same surface. Hyperikon 125w led corn bulb street light bulbs cob 625w equivalent large mogul e39 base outdoor and indoor area lighting model hyperstreet12539 50s 99 95 99 95. Gary mcvay gary a 300w incandescent puts out 3500 lumens and has a life expectancy of about 5000 hours. Led corn bulbs are named for their appearance as they resemble the corn on the cob.

Https amzn to 2clvdiu knog plus cob pair. 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. The cob contains individual led lights that can vary from 80 to 108 lights. Linked to the 3528.

But the difference among led light cob and smd is that cob leds have more diodes. A 40w cob led incandescent bulb replacement will put out 4000 lumens and has a life expectancy of 35 000 hours. This single circuit design. Led lights come in a variety of models.

On the contrary cob led light is not suitable for producing lights or bulbs that are color changing. 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. Numerous channels for modifications are needed to produce the color changing outcome.
