Chip on board (COB) is an LED packaging technology in which uncoated semiconductor elements are installed directly on a substratum or PCB with the help of a conductive or non-conductive adhesive and then wired for electrical connectivity. Different LED chips are packaged together as one module which light up and look like a lighting panel. They have the ability to provide better flexibility and also provide better light distribution capacity. Because of the tiny size of the LED chip, chip-on-board technology enables a much greater density of packaging than surface mounting technology which can provide user with great uniformity and higher intensity. These COBLED usually have great reliability, save large amount of energy, have better thermal management and also needs very less space.
Some of the factors responsible for the growth of this market are as follow:
- Rising demand for energy efficient lighting technique: When a product's energy use is decreased without influencing its production or final reaction, or the level of customer convenience it is known as energy efficient. These energy efficient lights have the ability to consume less energy and provide good quality & quantity of light. Today many people are replacing the traditional lamps, lights and other sources with these efficient lighting techniques because they also are cost effective. It is very beneficial to use efficient lighting because they can achieve peak load reduction, decrease electricity consumption, saves electricity and decrease greenhouse emissions
- Technological advancement and development in chip-on-board light emitting diodes: COB LED is way more different than the traditional LED. The recent kinds of LED lights used are chips on board LEDs. The use of these lamps is very flexible because they have the ability to generate big numbers of lumens in very tiny amounts of energy and are mainly used in smaller appliances such as a flash light in cameras, and other. In a single surface these LED consists of around 9 diodes. COB LED arrays minimize a need for producers of lighting to place separate LEDs on a printed circuit board (PCB) or placed them on a board for them. They combatively have easy manufacturing process
The global chip-on-board light emitting diodes market is segmented on the basis of application as illumination, automotive, backlighting, others, and high brightness lighting.
Some of the launches and acquisitions in the market are as follow:
- In January 2019, Lumitech announced the acquisition of COB (chip-on-board) divison from Tridonic Jennersdorf. This acquisition will help the company to produce high quality COB solution but to also increase the production of COB modules in their new site. With local growth and manufacturing knowledge, they will be able to offer the professional assistance to industrial and medical clients and strategically expand this section
- In May 2016, Cree announced the launch of their second generation high density COB LED. The new 6- and 9-mm-LES chip-on-board LEDs has the ability to enhance the lumen intensity and can decrease form factor in high- output SSL products. They can provide the large number of lumens in less space
“According to Data Bridge Market Research, global chip-on-board light emitting diodes market is set to witness a healthy CAGR of 38.67% in the forecast period of 2019- 2026”
Few of the major competitors currently working in the global chip-on-board light emitting diodes market are OSRAM Opto Semiconductors GmbH, CITIZEN ELECTRONICS CO., LTD, Cree, Inc, EVERLIGHT, Tridonic, Sharp Devices Europe., ProPhotonix, Luminus, Inc., Bridgelux, Inc., LG INNOTEK., SAMSUNG, Trans-Lux Corporation, NICHIA CORPORATION, ACUITY BRANDS LIGHTING, INC, Mouser Electronics, Inc., Excelitas Technologies Corp., Havells India Ltd., Lumileds Holding B.V, molex, TongYiFang, Component Distributors Inc., and others.
Today, COB LED is widely used in application with high power as they have high luminosity and high intensity. They have the capability to offer better color mixing due to which they are highly in demand for industrial and commercial purposes. In many countries, government is taking many initiatives so they can enhance the usage of energy efficient technologies which also creating new opportunities for this market.
