Quantum Dot Led Light Bulb

Coat it with a thin layer of special microscopic beads called quantum dots.

Quantum dot led light bulb. Quantum dot mixtures. A quantum dot display is a display device that uses quantum dots qd semiconductor nanocrystals which can produce pure monochromatic red green and blue light. This quantum dot tech helps grow more plants by making sunlight more powerful indoor farms can grow more food than fields by using special recipes of led lights to induce more plant growth. The converting part of the emitted light is converted into pure green and red light by the corresponding color quantum dots placed in front of the blue led or using a quantum dot infused diffuser sheet in the backlight optical stack.

Quantum dot displays use blue emitting leds rather than white leds as the light sources. Photo emissive quantum dot particles are used in a qd layer which uses the blue light from a backlight to emit pure basic colors which improve display brightness and color gamut by reducing light losses and color crosstalk in rgb. Moreover quantum dots can be advantageously used to generate warm white light sources like incandescent light bulbs or cool white sources like typical fluorescent lamps by changing the concentration of incorporated quantum dots. The introduction of quantum dots into led design marks a critical step forward in reducing the cost of led production and making them more affordable for the average consumer.

Light won t come just from newfangled bulbs. As a result for consumers looking to switch to leds the cost of led bulbs and lighting systems can be prohibitive. Just the other day i was moaning about the sorry state of consumer led bulbs and now nexxus lighting has released high end led unit that shines a more natural warmer light than others available. Two companies nexxus lighting and qd vision have paired up to change that with the former providing an 8 watt 75 watt equivalent led bulb and the latter providing a thin film of quantum dots.

However at this time these fantastic quantum dot light emitting diodes are limited by a physical effect which triggers after a certain photon barrier is crossed becoming highly inefficient. And you have what could become the successor to the venerable light bulb.
