Incandescent eligible rebirth? US researchers have developed "solid incandescent LED"

             Incandescent dying it, look right now who would buy incandescent bulbs, incandescent dying one leg has entered the coffin, but in the microscopic field, incandescent Reincarnated probably a new lease of life.

 

Dr. Yue Kuo Texas A & M University, and his former doctoral student with over Chi-Chou Lin new solid-state devices are based on the basic principles of the incandescent lamp is being developed.

 

 

 

 

The equipment and incandescent, is by heating the filament light. However, ordinary incandescent lamps, only 20-150 nanometer here filament diameter - and the bulb is very small, it is necessary to produce a semiconductor manufacturing plant.

 

Simply put, this is Edison's incandescent bulbs solid version, according to the inventor said, this bulb can work continuously for more than 7000 hours is not bad.

 

Kuo this bulb named "solid incandescent LED", D is not a diode in the meaning here, but the device equipment meant. In fact, the device can be regarded as a metal-oxide-semiconductor capacitors, formed in the conductor and the P-type silicon is sandwiched a thin layer of an amorphous insulating dielectric material. The uppermost portion of the transparent sheet made of a conductor (typically indium tin oxide), can allow light to pass through.

 

To make the device capable of emitting light, the researchers to equipment with a high voltage, a voltage high enough to be able to break down the middle of the dielectric material, under the action of high voltage, the dielectric material is converted into a large number of small and capable of long conductive fine wire. Once the dielectric material is broken down, the current can flow over these filaments. Because the filaments are also still some resistance, current flows to generate heat reaches a certain temperature began to glow, the light and then diverge to the outside through the transparent film. And ordinary incandescent bulbs, these light sources from the thousands of small luminous points.

 

And incandescent lamps, incandescent solid white light is emitted from the LED, span a very wide spectrum. This traditional LED has a very big difference, because the light emitted from the LED wavelength range is very narrow, if you want the LED white light, you have painted with a blue phosphor LED, or by mixing red, green and blue light bulbs it emits white light.

 

Speaking of light bulbs, the most important factor to consider is energy efficiency, the team preliminary measurements show that less than 1 percent of current is used to generate electricity is very low in this luminous efficiency light ...... ...... but Kuo want the device to eventually be able to exceed the conventional light-emitting efficiency incandescent bulbs.
