Puri experiment using new materials to manufacture LED bulbs

Puri April 5th announcement will not only have a great influence on the LED manufacturing industry, but also greatly reduce the production cost of solid state technology.

Blue California Co says it has successfully used silicon chips for the first time in commercial grade LED components.

Since the use of LED requires the use of many relatively expensive materials such as sapphire or silicon carbide, which prompted many companies to allocate a large amount of research and development funds to find cheaper alternatives.

While most companies are trying to reduce costs by using a lot of the same material, the focus has shifted to the silicon chip, the core of the computer chip.

In addition to the advantage of using this material at a lower cost, this method can be applied to existing semiconductor factories in theory.

Eight inch silicon nitride layer

However, to really put into practice, the company also had to face the fact that silicon is difficult to be applied to LED product applications. This process usually requires the deposition of gallium nitride on silicon wafers, and as a result the LED is made to be lower than the light-emitting diodes made of conventional materials.

In its announcement, the company said it had successfully used a eight inch silicon chip to reach up to a factor of 135 lumens per watt - meaning that solid-state technology would greatly reduce production costs in the future.

Bill Watkins, chief executive officer of the company believes that the new technology innovation will be unstoppable, the use of this new material can reduce the cost of production of 75% LED bulbs, and its price is less than $5.

The company said it expects the next two to three years to produce the first commercial gallium nitride products. (
