摘要： The object of the invention is to radiate light towards the outside, improve the luminous efficiency and obtain a high-intensity externally radiated light without hindering the light from being emitted on the entire surface of a phosphor layer. A glass substrate 2, that forms a light projection window, and a glass substrate 3, that forms a base bottom surface, are oppositely disposed at a predetermined interval to form a vacuum chamber, an anode electrode 5 is provided at a region at the center of the glass substrate 3, and a cathode electrode 6 is provided at a region on both sides of the anode electrode 5. A phosphor layer 7 is formed as a film on the anode electrode 5, an electron emission source 8 is formed as a film on the cathode electrode 6, and a gate electrode 9 is arranged above the electron emission source 8. An electric field is applied to the electron emission source 8 to emit an electron beam and make the electron beam uniformly fall onto the phosphor layer 7 in a parabolic shape to excite the phosphor layer 7 and emit light. Because only a vacuum space lies between the phosphor layer 7 and the glass 2, the intense light emitted by the excitation surface of the phosphor layer 7 is emitted from the glass substrate 2 towards the outside without any interference and suppresses electric power consumption while significantly increasing the quantity of light.

摘要： A light emitting apparatus capable of efficiently generating high luminance white light is provided. The present invention permits white light to be generated, without using low-emission efficiency white light emitters, by forming a light emitter layer 16 using a high-light emission efficiency blue light emitter and yellow light emitter. In this case, having at least a part of the blue light emitter particles 17 and at least a part of the yellow light emitter particles 18 exposed at a surface of the light emitter layer 16, respectively, allows both of such particles to be directly bombarded with electrons, thereby effecting a highly efficient electron excitation. Furthermore, the use of YAG or the like, as a yellow light emitter, which emits yellow light not only by electron excitation but also through photoexcitation by the blue light, permits said blue light to contribute to the emission of the yellow light, even when part of the blue light emitted by the blue light emitter particles, as it passes through the light emitter layer 16, is blocked by the yellow light emitter particles 18, whereby white light can be generated efficiently with a reduction in energy loss.

摘要： Provided herein is a light-emitting apparatus which is capable of causing the light emitted at the entire face of a fluorescent material to be exteriorly emitted with no interference and with enhanced light emission efficiency, thereby attaining an exteriorly radiated high brightness light. A cathode electrode 10 is mounted on a periphery of a transmission member 30, the anode electrode 15 is also mounted on a domain opposite to a light transmission member 30, and the surface 16a of the fluorescent material 16 to be mounted on a top layer of the anode electrode 15 is formed with a concave face. In accordance therewith, even when the cathode electrode 10 is offset mounted on a periphery of the light transmission member 30 it can be caused to precisely face the surface 16a of the fluorescent material 16 and the excitation light from the entire face of the surface 16a of the fluorescent material 16 can made incident onto the light transmission member 30 without interference from the cathode electrode 10 or the like.

摘要： Provided herein is a light-emitting apparatus capable of achieving both improved durability and higher brightness with an inexpensive and simple construction. A heat resistant glass substrate 51 is mounted in a vacuum chamber 5, and while an anode electrode 8 (and a light emitter 20) is mounted on the glass substrate, the glass substrate 51 is separated from a glass substrate 11. This precisely protects the vacuum chamber 5 from thermal damage due to light emission upon excitation, even when the current density between the cathode electrode 6 and the anode electrode 8 is controlled at a high level to cause the light emitter 20 to emit light at high brightness. Accordingly, this eliminates the need to make the entire vacuum chamber 5 excessively heat-resistant, permitting construction from an inexpensive material such as soda-lime glass; consequently both improvements in the durability of the light-emitting apparatus 1 and enhancement in brightness thereof can be accomplished with an inexpensive and easy construction.

摘要： A light-emitting apparatus of the present invention maintains an anode electrode 5 at a higher positive electric potential than a cathode electrode 15, applies an electric field to a cold-cathode electron emission source 16 by controlling a gate voltage applied to the cathode electrode 15 with a gate electrode 10, and emits excitation light from a phosphor 6 irradiated by an electron beam released from the cold-cathode electron emission source 16. The light-emitting apparatus of this invention emits the excitation light not only from the opposite side of the electron beam-irradiated surface of the phosphor 6 through a glass substrate 2, but also from the electron bean-irradiated surface of the phosphor 6 by reflecting the excitation light with a gate reflection surface 12 on the gate electrode 10 and emitting it through an unobstructed area Ro of the glass substrate 2. This eliminates the wasted excitation light emitted and absorbed within the apparatus as in the conventional light-emitting apparatuses to thereby improve the luminous efficiency and substantially increase the amount of light emitted outside from the entire illumination surface.
