Abstract
The invention discloses an anodic aluminum oxide photonic crystal capable of improving the luminous efficiency of an incandescent lamp and a preparation method and application thereof. An incandescentlamp shell made of an anodic aluminum oxide photonic crystal can reflect near-infrared band radiation and transmit visible over-band radiation, so purposes of improving luminous efficiency of the incandescent lamp and reducing heat loss are achieved, and the possibility is provided for the incandescent lamp to be on duty again.
Description
technical field [0001] The invention belongs to the technical field of photonic crystal materials, and in particular relates to an anodized aluminum oxide photonic crystal for improving the luminous efficiency of an incandescent lamp, a preparation method and an application thereof. Background technique [0002] Incandescent lamp is a kind of heat radiation light source, its filament temperature reaches about 3000K when it works, a large amount of electric energy is converted into heat energy, and only 2% to 4% of electric energy is converted into light that the eyes can feel. Due to its low energy conversion efficiency, it is being replaced by other light sources. However, due to the continuity of the spectrum of incandescent lamps; the color rendering index is as high as nearly 100, which is much higher than other light sources; the luminous flux is much larger than other cold light sources; the preparation cost is low, about 1 / 26 of LED light sources, and does not contain...
