Light emitting diode(LED), which emits a maximum intensity at 710 nm and 60% of its maximum at 760 nm, was adopted as an alternative light source to inefficient incandescent light. With the array of the LEDs adjustable to the reactor wall 95% of the light energy was saved over the ...
Light-Emitting Diode (LED) is a semiconductor device that produce light when electricity passes through them. They operate on electroluminescence, emitting efficient, durable, and long-lasting illumination.
The light-emitting diode light bulb comprises: a light-emitting diode light source module; a base, wherein the light-emitting diode light source module is disposed on the base; and a driver portion to drive the light-emitting diode light source module, comprising a rotation shaft, wherein ...

Organic Light Emitting Diode (OLED) is an emerging technology as one of the strong candidates for next generation solid state lighting with various advantages such as thin flat shape, no UV emission and environmental benefits. At this moment, OLED still has a lot of issues to be solved before...
By introducing this lateral-hole-diffusion layer (LHDL) at the anode side of organic light-emitting diodes (OLEDs), both reduced efficiency roll-off and enhanced operation stability are demonstrated. In conventional OLEDs, balance in electron and hole currents is typically achieved by leakage of ...
