bridgelux enables the led revolution from behind the scenes

LED lighting is a fascinating technology.
It\'s not like an incandescent lamp-in an incandescent lamp, you heat a filament until it shines (
You produce 90% of the heat and a relatively small amount of light, which is the inevitable result).
This is also not like fluorescence-the current stimulates the mercury vapor and eventually causes the phosphorus coating on the tube to glow.
Solid-State LEDs are a completely different technology.
They are semiconductor devices that produce light due to current.
Unlike incandescent lamps and fluorescent lamps, LED lights are directional-you can focus them in one direction.
You can talk to them.
LED lighting is related to chips, which makes design, production and innovation a completely different game.
One of the companies that entered the game early on was Bridgelux, who was an innovator from the beginning.
Among the other companies that have a high reputation in the field of lighting, bridgelux first created a mass production process for growing LED chips on a silicon lining base-a development that is now on the market and will result in significant cost reductions.
The company is also a pioneer in developing so-called \"chips\". on-
The structure of the board, which is the basis for improving the light quality and color control, reduces the production cost and time to market for various lighting applications.
Bridgelux has now gone further and developed what they call the Vero platform to further reduce the cost of LED lights (
In terms of lumens per dollar).
The Vero platform also creates higher connectivity and integration capabilities for the growth of smart lighting applications in the future.
Then sold to the original equipment manufacturer (OEMs)
In turn, the products they produce carry other people\'s brands.
So as society squeezes out more value from every kilowatt, what Bridgelux does is highly leveraged, and their innovation and productivity gains are critical
Consumed an hour of electricity.
I recently spoke with Brad Burrington, CEO of the company, in an attempt to better understand this highly technical and complex area and to understand what he thinks about the industry.
Bullington has worked in Bridgelux for four years and has served as CEO for the past year and a half.
He led the company through a lot of changes to achieve today\'s goals.
Bullington commented that Bridgelux, originally established in 2002, is a capital equipment company-they will create tools for developing chips and chips needed for led development.
They applied for some key patents, but finally realized that it might be easier to join the LED industry than to become a capital equipment company.
They quickly also realized that if you want to beat the existing lighting technology, it is necessary, as Bullington said, \"to span certain price performance levels to enable new applications to move to new technologies.
Some of the challenges faced by Led are the same as those affecting other lighting technologies (
Low level here though)
The production of light will also produce unwanted heat.
Bullington commented that this was the initial technical challenge that had to be addressed.
Therefore, the company decided to add \"value-added packaging \". e.
Bring chips and create the best layout or so-called \"array architecture\" to their portfolio.
Bridgelux is particularly keen to develop the ability to create high-quality light in general lighting while addressing the heat and power management challenges brought about by led.
Another thing about former CEO Bullington (Bill Watkins)
What other members of the team do is focus on gan (GaN)
Chip technology.
They chose the GaN technology, especially the 8 \"silicon substrate, because it has lower cost points and ease of useof-
Enter the mature silicon manufacturing field represented by Intel, Toshiba and other companies.
Infrastructure for building Silicon
Basic technology is in place.
The challenge is that the application of gan nitrogen on Silicon presents specific technical barriers.
On January 2012, the two companies signed a cooperation agreement-on-
Silicon LED wafer.
By October, the Partnership announced GaN-on-silicon wafers.
In 2013, the two companies deepened their strategic relationship and announced a manufacturing agreement to position Toshiba as a GaN-on-
Bridgelux will focus on packaging, while silicon-based LED chips.
Toshiba produced some GaN-on-
But mass production will not begin until later this year.
Looking back, Bullington commented on the development of LED lighting technology in three different stages.
The first phase is to do a good job of core technology and reduce prices where they are attractive to customers. Phase Two (
This industry is the later stage of this stage)
Solved the \"encapsulation\" problem and created an architecture and chip alignment that optimizes performance.
The third phase is what Bullington calls the activation phase of light.
It became very interesting and creative after that.
Because with LEDs, you can do something with color and connectivity that you can\'t do with a non-solid light source.
Given the rapid innovation and growth in the LED space, where does Bullington think this will go?
First, he saw continuous improvement in costs.
The effectiveness of the consumer, which hurts the bottom line of the LED player to some extent.
At the same time, Bullington also expects that the market penetration rate of LED will continue to grow rapidly, and the application of lighting technology in human beings will continue to develop.
The CEO of Bridgelux is keenly aware that the industry and his company are at a critical juncture in the development of lighting technology.
He intends to give Bridgelux a key catalyst in this transformation.
