Abstract
A planar light source is composed of a primary point or line light source and planar luminescent screen coated by luminous material. When the primary light from said light source passes through said planar luminescent screen, it excits the luminescent material to generate the secondary light. The light from said screen is the synthetic light of primary light and secondary light or the secondary light transformed from primary light. Its advantages are high light uniformity and brightness, soft light and low cost.
Description
The present invention relates to light supply apparatus, particularly a kind of planar light source device.
Light source and people's life, work have very closely gets in touch, and it is widely used in aspects such as industry, agricultural, scientific research, national defence, medical treatment, traffic.Edison has invented incandescent lamp in the 19th-century later stage, started human history of throwing light on artificial light source, but incandescent lamp can only be regarded a kind of spot light as.In nineteen thirties fluorescent lamp appearance, it is great advance in the light source field.Many advantages such as fluorescent lamp has the light efficiency height, photochromic good, life-span is long and radiant heat is few, but it can only regard a kind of line source as.Occurred multiple light source afterwards again successively, as sodium vapor lamp, neon lamp, mercury lamp, xenon lamp, metal halide lamp and LED light lamp etc., these lamps also all can only be regarded spot light or line source as.For a long time, people dream of to occur a kind of area source.Nineteen forty-seven has been invented transparent conducting glass, electroluminescent (EL) lamp that utilizes it and electroluminescent principle to develop is a kind of real area source, people had placed on very big expectation for it at that time, but its luminous efficiency is very low, explore and research through people are long-term, it still can't be used as illumination.Up to now, a kind of illumination planar light source device with practical value does not also appear.
The purpose of this invention is to provide a kind of illumination planar light source device with practical value, it is made up of disposable light source and face luminescent screen, disposable optical excitation face luminescent screen by disposable light source sends produces secondary light, just can obtain a kind of luminous planar light source device of face that produces.
Be elaborated below.
As everyone knows, incandescent lamp is according to heat radiation principle and luminous, and fluorescent lamp, sodium vapor lamp, neon lamp, mercury lamp, xenon lamp and metal halide lamp wherein need by luminescent material sightless short wave ultraviolet light is converted to visible light for fluorescent lamp according to the discharge principle in the gas and luminous.Typical fluorescent lamp mainly is made up of with two electrodes that are positioned at lamp tube ends the glass-tube of luminescent material coated on inwall, electrode is that helical form forms by the tungsten filament coiling, coated has the alkaline earth oxide that can launch electronics on it, fluorescent tube inside charges into small amount of mercury and a certain amount of argon gas after vacuumizing.After the lamp tube ends electrifying electrodes, the electronics of launching from alkaline earth oxide collides by direct or indirect process and mercury atom, make in the mercury atom electronics from ground state transition to various excitation state, when the electronics that is in excitation state when spontaneously ground state is returned in transition, to give off the 254nm short wave ultraviolet light in a large number, excite down at the 254nm short wave ultraviolet light, luminescent material produces visible light, the luminous basic mechanism of fluorescent lamp that Here it is.
If luminescent material is not that coated is at the glass-tube inwall, but coated outside glass-tube one have on the planar luminescent screen (face luminescent screen), then the 254nm short wave ultraviolet light that the time sends in work of fluorescent lamp is radiated on the face luminescent screen through glass-tube, the energy excitation light-emitting material is luminous equally, thereby obtains a planar light source device.We are called disposable light source with fluorescent lamp, the light that disposable light source is sent is called disposable light, luminescent material on the face luminescent screen is embedded photoluminescent material (hereinafter to be referred as a luminescent material), and it can be luminous under the exciting of disposable light, and we are called secondary light with the light that the face luminescent screen is sent.Common disposable light wavelength is less than the secondary light wavelength.If luminescent material is a white luminescent material, then can obtain to send the planar light source device of white light.
Because when the 254nm short wave ultraviolet light passes through common fluorescent tube and other material, decay is big, and it is harmful to human body and human eye, in order to address these problems, can adopt the longer light of wavelength as disposable light, the for example long wave ultraviolet light about 365nm (being designated hereinafter simply as ultraviolet light), purple light, blue light, bluish-green coloured light, corresponding disposable light source is called ultraviolet, purple, blueness, blue-green light source, embedded photoluminescent material on the face luminescent screen also needs correspondingly to change simultaneously, and therefore following three class planar light source devices are arranged:
