Why it was time the invention of the blue LED was recognized for a Nobel Prize

Why it was time the invention of the blue LED was recognized for a Nobel Prize

This month, Isamu Akasaki, Hiroshi Amano, and Shuji Nakamura were jointly awarded the Nobel Prize for Physics for the invention of “efficient blue light-emitting diodes (LEDs) which has enabled bright and energy-saving white light sources”.

Why is the creation of the blue LED a significant achievement worth the Nobel Prize? Essentially, these three scientists figured out how to grow gallium nitride, which enables blue LEDs to be produced. When you add red and green LEDs to blue LEDs, or when a blue LED is coated with a phosphor, you create white light. White light made the LED light bulb possible and is the very reason that energy efficient lighting exists today. As the Nobel Committee stated, “Incandescent light bulbs lit the 20th Century; the 21st Century will be lit by LED lamps”.

New Research Poll: The Majority of Business Owners and Managers Prefer to Finance the Upfront Costs of LED Lighting Implementation

A new poll commissioned by Leapfrog Lighting verifies a preference for financing the implementation costs of LED lighting. A total of 66.3% of business owners and managers indicated a preference to finance.

LED lighting and the MacAdam Ellipse

If you look closely at the fine print in the technical datasheets or product boxes of lighting products, you will find reference to an ANSI specification C78.377-2008, which is associated with Correlated Color Temperature (CCT). This specification sets standards, or more specifically, tolerances, for color consistency among light sources. How these tolerances—what is considered anMore >More >

New Research Reveals That the Majority of Business Owners Use, or Plan to Use, LED Bulbs, Although Half or Them Delayed Due to Upfront Costs

As an industry, we’ve done a great job, according to a new research poll, educating users on the energy benefits and durability of LED bulbs. We seem to have been less convincing on the issue of upfront cost. A new survey of 200 business owners and managers revealed that upfront cost is the leading reasonMore >

New Poll from Leapfrog Lighting: Only 49.6% of business owners and managers entirely believe claims on LED bulb packaging

New Poll from Leapfrog Lighting: Only 49.6% of business owners and managers entirely believe claims on LED bulb packaging

When only 49.6% of business owners and managers believe LED bulb packaging claims—as found in a recent independent poll of business owners—this is clearly an underwhelming endorsement for the majority of available LED bulbs. Random panel polls are statistically accurate measures of opinion. Confidence in manufacturer claims in this poll result is an opinion—but it’sMore >
