The specific embodiment
Below in conjunction with diagram, the preferred embodiments of the present invention are described in detail.
The airfield aid structure of the preferred embodiment of the present invention as shown in Figure 1, its assembly structure figure comprises the lampshade 10 and the lamp socket 40 that adopt transparent or semitransparent material to make as shown in Figure 2.Be provided with the light source fixed head 50 that is used for fixing light source in lampshade 10, light source fixed head 50 is connected on the lamp socket 40.On light source fixed head 50, be fixed with a white LED light source 30 at least.
As shown in Figure 2, consult Fig. 5 simultaneously, the light path of white LED light source 30 is provided with light-distribution lens 20, is used for the light refraction that white LED light source 30 sends is become parallel collimated light outgoing.Collimated light light path through light-distribution lens 20 outgoing is provided with yellow filter 60, is used to aim at direct light and filters, and realizes the gold-tinted illumination, to satisfy the requirement of airfield aid.And the plane of light incidence preferred parallel of the plane of light incidence of light source luminescent face, light-distribution lens 20 and yellow filter 60 is provided with.
Wherein, the light-distribution lens 20 preferred Fresnel Lenses that adopt.Also can adopt non-spherical lens, the outer surface of this non-spherical lens is a sphere, and inner surface middle part is recessed, forms concavees lens with outer surface, is used to disperse center intensity that white LED light source sends than the high light line; The inner surface periphery projection is formed convex lens with outer surface, be used to assemble be positioned at that white LED light source sends around intensity than decreased light.Adopt such non-spherical lens, the light refraction that white LED light source can be sent is uniform collimated light outgoing.
In the present embodiment, white LED light source 30 preferred employing colour temperatures are the white LED light source of 3000～3500K.
In the present embodiment; yellow filter 60 designs for coating single side; the optical filter body generally adopts glass; its plated film face is the one side relative with plane of light incidence; on glass when inciding like this by the collimated light of light source outgoing, can incide the plated film face by behind glass-reflected and the absorption portion ultraviolet light; with protective coating, the logical wavelength of preferred employing band is the yellow filter of 530～780nm.
In the present embodiment, light source fixed head 50 can adopt the material of perfect heat-dissipatings such as aluminium or copper material to make, one side energy fixed light source, the heat that also can well light source be produced in lampshade 10 is passed to lamp socket 40 on the other hand, thereby reaches the purpose of heat radiation.
As shown in Figure 5, the primary optical axis of white LED light source 30 is almost perpendicular to light source fixed head 50, and the light that is sent by white LED light source 30 becomes the collimated light outgoing through behind the light-distribution lens 20.After filtering through yellow filter 60 again, obtain to satisfy the emergent light of gold-tinted chromaticity coordinates requirement.
Because white LED light source 30 is to excite yellow fluorescent powder by blue chip, go out white light by blue light and yellow light mix again, the composition of its gold-tinted is than higher, and the light decay of white LED light source is more stable, when approximately the luminous flux during 100 ℃ of junction temperatures is 25 ℃ more than 85%, therefore the mode of using white LED light source 30 to add yellow filter 60 obtains gold-tinted, can satisfy the requirement of airfield aid to gold-tinted.
Concrete luminous intensity distribution angle can be regulated with the distance of white LED light source 30 by parameter and the light-distribution lens 20 of revising light-distribution lens 20.In the present embodiment, for generation meets the country and the gold-tinted hot spot of International airport aid-to-navigation light standard, the distance between light-distribution lens 20 and the yellow filter 60 is preferably 2～5mm; Distance between white LED light source 30 and the light-distribution lens 20 is preferably 7～10mm.
The logical wavelength of band, yellow filter 60 that the factor that influences final gold-tinted chromaticity coordinates comprises the energy of white LED light source 30 and Wavelength distribution curve, yellow filter 60 and the angle of white LED light source 30 primary optical axis etc., these factors can be set in actual Design of Luminaires as required.
In the present embodiment,, also can realize good spotlight effect in a conned space even adopt single light-distribution lens 20 of single white LED light source 30 collocation.
According to the gold-tinted luminous intensity lighting demand of general airfield aid, as shown in Figure 4, four white LED light sources 30 can be set on light source fixed head 50, equal correspondence is provided with light-distribution lens 20 on the light path of each white LED light source 30.On the collimated light light path of each light-distribution lens 20 outgoing, all correspondence is provided with yellow filter 60.
When adopting four white LED light sources 30, can adopt the light-distribution lens 20 that splices and combines by four Fresnel Lenses, its structure is as shown in Figure 3.Or adopt the light-distribution lens that is combined into by the connecting method of Fresnel Lenses among Fig. 3 by four non-spherical lenses.
As shown in Figure 6, in further embodiment of the present invention, can be on the two sides of light source fixed head 50 corresponding a plurality of white LED light sources 30, light-distribution lens 20 and the yellow filter 60 of being symmetrical arranged, also can be at corresponding a plurality of white LED light sources 30, light-distribution lens 20 and the yellow filter 60 of being symmetrical arranged all around of light source fixed head 50, so that airfield aid can be realized comprehensive irradiation, and luminous even.
Wherein, preferably white LED light source 30, light-distribution lens 20 and yellow filter 60 are obliquely installed with respect to ground or horizontal plane, to satisfy country and international standard requirement airfield runway airfield aid irradiating angle.
In sum, the present invention utilizes white LED light source to add light-distribution lens and yellow filter, and the white light that white LED light source is sent becomes the gold-tinted outgoing, replaces the yellow light LED of low light efficiency, high light decay.Solved the problem that yellow light LED can't reach the high light intensity requirement of airfield aid, improved light efficiency and lux maintenance, not only saved cost, reduced energy consumption, and the gold-tinted that is produced can reach the relevant criterion of country and International airport aid-to-navigation light.
Should be understood that, for those of ordinary skills, can be improved according to the above description or conversion, and all these improvement and conversion all should belong to the protection domain of claims of the present invention.
