Abstract
The invention belongs to the field of lamps, and provides a lens, which is used for gathering light rays emitted by a light source. The light inlet surface, which is close to the light source, of the lens is a plane; the light outlet surface, which is far away from the light source, of the lens is formed by connecting a plurality of concentric circular flanges in sequence; and the thickness of the lens is reduced in sequence from the center of the lens to the edge. The invention further provides a high-luminous-intensity runway guard light provided with the lens. Light rays emitted by the light source are converged by using the lens, and the lens plays the same roles as a reflector and a yellow light filtering plate of the conventional runway guard light, so that the lens can be adopted instead of the reflector and the yellow light filtering plate of the conventional runway guard light, the manufacturing cost of a lamp is reduced remarkably, and the installing procedures of the lamp are reduced.
Description
Technical field
The invention belongs to field of light fittings, relate in particular to a kind of lens and use the high light intensity runway alert lamp of these lens.
Background technology
At present, existing high light intensity runway alert lamp is to adopt halogen tungsten lamp and reflector to realize luminous intensity distribution.The weak point of this kind light-configuration mode is, needs the special rafifinal reflector of making realize spotlight effect, and light-emitting window need arrange a Yellow filter plate specially the light that light source sends is become gold-tinted.
Summary of the invention
The object of the present invention is to provide a kind of lens and use the high light intensity runway alert lamp of these lens, it utilizes lens to replace reflector and Yellow filter plate of existing high light intensity runway alert lamp to realize luminous intensity distribution.
The present invention realizes like this, a kind of lens, the light that is used for light source is sent carries out optically focused, described lens are the plane near the incidence surface of described light source, described lens are connected in sequence by a plurality of donut flanges away from the exiting surface of described light source, and the thickness of described lens successively decreases to the edge successively from described lens centre.
Particularly, the incidence surface of described lens is coated with one deck Yellow filter film.
Particularly, the angle between two tangent lines done along this two adjacent annular flange of the intersection point of described each arc ring two adjacent annular flange is 155 ~ 165 °.
Particularly, the thickness of described lens is 3 ~ 25mm.
Particularly, the incidence surface of described lens is 50 ~ 90mm to the distance of described light source.
Preferably, described light source is halogen tungsten lamp.
The present invention also provides a kind of high light intensity runway alert lamp, comprises lamp body and the lens that are tightly connected with described lamp body, is provided with a light source in the cavity that described lamp body and lens cooperation form, and described lens are foregoing lens.
Particularly, described lens compress and are fixed on the described lamp body by a fixed head.
Preferably, be provided with a sealing ring between described lens and the lamp body, described sealing ring is fixed by described fixed head.
The present invention utilizes lens that the light that light source sends is converged, play the effect identical with the Yellow filter plate with the reflector of existing runway alert lamp, therefore these lens can substitute reflector and the Yellow filter plate of existing runway alert lamp, significantly reduce the manufacturing cost of light fixture, and reduced the installation procedure of light fixture.
Description of drawings
In order to be illustrated more clearly in technical scheme of the present invention, to do to introduce simply to the accompanying drawing of required use among the embodiment below, apparently, accompanying drawing in describing below only is some embodiments of the present invention, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the schematic diagram of the lens that provide of the embodiment of the invention;
Fig. 2 is the cutaway view of the A-A direction among Fig. 1;
Fig. 3 is the decomposing schematic representation of the high light intensity runway alert lamp that provides of the embodiment of the invention;
Fig. 4 is the installation diagram of the high light intensity runway alert lamp among Fig. 3.
The specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described.
As depicted in figs. 1 and 2, a kind of lens 1 that the embodiment of the invention provides, the light that is used for light source is sent carries out optically focused, lens 1 are the plane near the incidence surface 11 of light source, present embodiment plates the oxide yellow magnesium by sputtering technology at incidence surface 11, thereby form one deck Yellow filter film at incidence surface 11, the light that this Yellow filter film is used for light source is sent becomes gold-tinted, satisfies runway alert lamp and utilizes gold-tinted to send the requirement of restricted speed signal; Lens 1 are connected in sequence by a plurality of annular flange 121 away from the exiting surface 12 of light source, and the thickness of these lens 1 successively decreases to the edge successively from the center of lens 1.
Particularly, angle α between two tangent lines that the intersection point of two adjacent annular flange 121 is done along this two adjacent annular flange 121 is 155 ~ 165 °, exiting surface 12 is by this structure setting, can make light after the refraction of exiting surface 12 places better optical axis 13 directions to lens 1 converge; The thickness of lens 1 is 3 ~ 25mm, and lens 1 are 50 ~ 90mm to the distance of light source, the preferred halogen tungsten lamp of light source.
The light that sends when light source through lens 1 the time, light enters from the incidence surface 11 of lens 1, when light arrives the exiting surface 12 of lens 1, light produces refraction at a plurality of annular flange 121 places of exiting surface 12, converge through axis 13 directions of the light after these a plurality of annular flange 121 refractions to lens 1, thus the effect that makes lens 1 produce optically focused.
Because lens 1 role of the present invention is identical with Yellow filter plate role with the reflector of existing runway alert lamp, therefore, these lens 1 can substitute reflector and the Yellow filter plate of existing runway alert lamp, have significantly reduced cost.
As shown in Figure 3 and Figure 4, the embodiment of the invention also provides a kind of high light intensity runway alert lamp 2, comprise lamp body 21 and the foregoing lens 1 that are tightly connected with lamp body 21, be provided with a light source 22 in the cavity that lamp body 21 and lens 1 cooperation form, the preferred halogen tungsten lamp of light source, lens 1 compress and are fixed on the lamp body 21 by an annular hollow fixed head 23.
Particularly, be provided with a sealing ring 24 between lens 1 and the lamp body 21, sealing ring 24 is fixed by fixed head 23, thereby realizes being tightly connected between lens 1 and the lamp body 21.
High light intensity runway alert lamp 2 of the present invention is compared with existing high light intensity runway alert lamp, the present invention utilizes lens 1 that the light that light source 22 sends is converged, play the effect identical with the Yellow filter plate with the reflector of existing runway alert lamp, therefore, these lens 1 can substitute reflector and the Yellow filter plate of existing runway alert lamp, significantly reduce the manufacturing cost of light fixture, and reduced the installation procedure of light fixture.
The above is preferred embodiment of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications, these improvements and modifications also are considered as protection scope of the present invention.
