Abstract

The field emission light source includes following components: a substrate with flattening surface; a conductive cathode formed on surface of the substrate; an insulating layer is setup on the conductive cathode; the multiple electro emitters setup at the insulating layer; a anode layer is apart from the conductive cathode in certain distance, and a fluorescent layer setup at surface of the anode layer; when bombed by emitted electrons, the fluorescent layer is capable of emitting visible light; being in use for emitting electros, the electro emitter includes a substrate part and a top part. The substrate part is connected to the insulating layer. The material of the substrate part is carbon similar to diamond, and the material of the top part is niobium.

Description

【Technical field】 [0001] The invention relates to a light source, especially a field emission light source and a backlight module using the light source. 【Background technique】 [0002] Artificial lighting sources can generally be divided into incandescent lamps, discharge lamps and solid-state light sources, including incandescent lamps, fluorescent tubes, light emitting diodes (Light Emitting Diode, LED), halogen lamps, high-pressure gas discharge lamps (High Intensity Discharge, HID) and so on. A lighting source. Among them, the incandescent lamp emits heat after the tungsten wire is energized, and generates a large amount of heat at the same time. Its luminous efficiency is low (about 8-15 lumens / watt), and its brightness is limited. Ultraviolet light hits fluorescent materials to emit visible light, which is generally used for ordinary daily life lighting. Its advantage is high luminous efficiency (up to 80 lumens / watt), and its disadvantage is that it contains mercury...
