Description

200414266 V. Description of the invention (1) [Technical field to which the invention belongs] The present invention relates to a cold cathode field emission type flat lamp with nano carbon material and a manufacturing method thereof, and is particularly suitable for lighting. [Prior art] Conventionally, light-emitting devices that emit light by applying voltage are mainly fluorescent lamps and ordinary light bulbs. Fluorescent lamps and ordinary light bulbs are bulky, have low luminous efficiency, and generate heat, causing many restrictions on use and waste of energy. In today's era that emphasizes energy conservation, traditional fluorescent lamps and ordinary light bulbs no longer meet the needs of today's users. Energy waste is a very important issue in advanced countries in the world, and China cannot stay aloof. Therefore, it can effectively improve energy conversion efficiency and reduce energy waste. Is the future trend. The lighting mechanism of fluorescent lamps and traditional light bulbs is limited by physical characteristics, and the value of luminous efficiency cannot be improved. Under the diverse requirements of current light source applications, large-area planar light sources are often used for lighting, but fluorescent lamps and traditional Due to the limitation of the light emitting configuration of the light bulb, an additional light guiding device must be added to increase the area of the mask and the uniformity of the light, which will cause an increase in cost. Therefore, under the premise of saving energy, improving energy conversion efficiency and generating high brightness, a light source with high luminous efficiency, high brightness and no heat generation is needed to overcome the difficulties that fluorescent lamps and traditional light bulbs cannot solve. Traditionally, fluorescent lamps and traditional light bulbs are mainly used as the main light source in lighting devices. However, the non-planar light source often causes uneven brightness in the illuminated area. Only the use of a planar light source can improve this disadvantage. Therefore, an urgent need is High luminous efficiency, high brightness and non-heating planar light source

Description of the invention (2) Replacing existing fluorescent lamps and traditional light bulbs, to overcome the difficulties that fluorescent lamps and traditional light bulbs cannot solve, to improve energy efficiency. [Invention § Mainly, in terms of light lamps, when the light is large, the beam will diverge to provide a source of material field. The starting material for the electric field that can produce light-emitting materials in the increase is 100 nm, which makes the nano-material cold. Content] The system uses a traditional light bulb, which causes the light in the other area to have a small difference. The purpose of the rice carbon material is to use low-energy materials to send and receive the additional carbon material. The light source used for lighting is limited by the luminous efficiency, brightness and energy loss (generation of heat) and traditional light bulbs cannot be the next generation of energy-saving lighting sources. The fluorescent light and traditional light bulbs are non-planar light sources. Poor degree, easy to appear the local brightness difference phenomenon, which presents a large contrast between light and dark, which is not conducive to the use of lighting; it is not easy to form a large area of light from a relatively angle. The high-efficiency, high-brightness, and non-heating flat-type nano-type flat lamp of the present invention can improve energy conversion efficiency and effectively improve uniformity of illumination. The invention uses the excellent field emission characteristics of nano-carbon materials to generate a large number of high-density electron beams, which are excited by electrons to strike the luminescent material to emit light. The luminous brightness depends on the increase in the number of electrons released by the nano-carbon material. . Since the nano electric field (turn on field) is less than 1 v / # m, the use of cold cathode field emitters can improve energy conversion efficiency. Moreover, in the one-dimensional nanometer-scale structure, the one-dimensional nanometer carbon material has a length of several tens of micrometers ("m"). The high-length-wide carbon material has a good field emission enhancement effect. Field emitters can effectively enhance

Description of the invention (4) can also be used in nano-carbon material units The electric field formed by the cathode and the anode on the light-transmitting plate allows the nano-carbon material to emit electrons, and the electrons impinge upon the light-emitting material to emit light, thereby forming a two-pole nano-carbon material cold-cathode field-emitting flat lamp. Carbon material cold cathode field emission type flat light is a flat light source. Nano technology is introduced into light-emitting elements. The physical properties of nano carbon material itself greatly reduce the initial electric field and increase the current density, which improves the energy conversion efficiency. In order to reduce energy waste, the planar light emitting mechanism can evenly distribute the light intensity in the illuminated area, and generate a large area of high uniform brightness area, which improves the appearance of fluorescent lamps and traditional light bulbs. The phenomenon of uneven illumination. The present invention has a nano-carbon material cold-cathode field emission type flat lamp and a novel manufacturing method, which can be used by the lighting industry and has the effects of power saving, high brightness, and a flat-type light source. patent.
