Quanlight LED Technology

HOME >> TECHNOLOGY

Quanlight’s LED technology is based on novel material science. Conventional AlInGaP-based YAR LED chips have reached the maximum performance possible given the material used.

In order to make a quantum leap in the performance of YAR LED chips, a novel material with superior fundamental properties must be used. Quanlight’s technology provides this type of breakthrough, significantly advancing YAR LED performance capabilities and enabling further expansion of the LED market.

The Quanlight technology includes two fundamental but related innovations – a new material (InGaNP) with superior fundamental properties over conventional AlInGaP, and a novel LED structure. As a result, Quanlight’s LEDs will decrease initial cost per lumen, while simultaneously resolving a color stability issue which presently haunts the YAR segment of the LED industry.

Quanlight’s InGaNP LED technology has three critical advantages over conventional AlInGaP technology. Our manufacturing process is simpler and cheaper, our technology provides a four-fold improvement in light-output per unit area, and it offers a five-fold improvement in color stability.

Brighter while using the same amount of power

Quanlight LEDs maintain their efficiency as heat increases much better than conventional AlInGaP LEDs. While all LEDs drop in light output with increased heat, Quanlight LEDs will drop at about half the rate of conventional red LEDs.

Cost less to manufacture

By growing directly onto a transparent GaP substrate, Quanlight LED wafers eliminate the steps required to transfer the epi-layer and eliminate the need for a second substrate. With reduced material and process costs, Quanlight LEDs grown at high volumes should be significantly less expensive to produce.

Improve the overall color stability of the device

Due to the superior fundamental properties of the Quanlight material, our LEDs will shift in color only one-fifth as much as AlInGaP LEDs with rising temperature. In lab testing, Quanlight red LEDs shifted by ~3 nm over a 100 C increase in temperature, compared to published data for conventional red LEDs showing a 15 nm shift over the same temperature range.
