Abstract
The invention pertains to the technical field of illumination optics, relates to an illuminant arrangement using a halogen lamp as light source, concentrating energy by a elliptic spherical reflecting mirror, and controlling the divergent angle of light beam by a Fresnel lens and a cylindrical mirror array. The invention comprises a halogen lamp, a elliptic spherical reflecting bowl, a slit group, a Fresnel lens, and a cylindrical mirror array. The elliptic spherical reflecting mirror is used for concentrating energy, the combination of the Fresnel lens and the cylindrical mirror array has not only guaranteed the full evening of light of the outgoing light beam in horizontal and vertical direction, but also guaranteed the outgoing angle; by the elliptic spherical reflecting bowl, the energy loss in the light source is minimized, so most energy is concentrated on the slit, this guarantees that the outgoing beam from the light box is visible and the lamp color is identifiable in certain distance. The invention is of simple and reliable structure, high operability, can be applicable for carrier-borne indication and the landing-assistant system for flying.
Description
One, technical field
The invention belongs to the light optics technical field, relate to naval vessel pilot light source apparatus.
Two, background technology:
The naval vessel is when surface navigation, and the traditional lamp signal except modern means of communications such as radio communication of the communication between the naval vessel is the same to play irreplaceable effect when transmission information and order.Along with the ocean development of modernization, between the naval vessel, during communication between naval vessel and the carrier-borne aircraft, light signal still plays crucial effect.Make a general survey of various countries naval when greatly developing the radiotechnics communication, still attach great importance to the research and development of traditional carrier-borne lamp box technology.At present, in the world to the shooting angle of carrier-borne lamp box and the requirement of comparison standard is all arranged service life.In order to catch up with world level as early as possible on the field of carrier-borne lamp box research and development, we have invented a kind of new type light source device that is used for the naval vessel indication on existing nonimaging optics theoretical foundation.
No. 200320115436, known Chinese utility model patent, a kind of " the pipe integrated navigation light light source of light-emitting diodes " disclosed, having solved the belt angle of arranging of tube and tube becomes 45 degree, makes the complementary ability of luminosity, easily produces the problem at dark angle, make horizontal direction 360 degree ring luminosity even, do not influence vision, but can not control the angle of horizontal direction and vertical direction.
Three, summary of the invention:
Main purpose of the present invention is to adopt the light source of Halogen lamp LED as lamp box, utilize the ellipsoid reflector to concentrate the energy of light source, by slit, Fresnel Lenses and cylindrical lens array the light beam of light source outgoing is carried out angle restriction, make light beam remain on 18 '～40 at the subtended angle of vertical direction ' between, the subtended angle of horizontal direction remains between 40 °～60 °.
To achieve these goals, the invention provides a kind of light supply apparatus that is used for the naval vessel indication.
Detailed content of the present invention: comprising: halogen light source 1, ellipsoid reflector 2, slot set 3, Fresnel Lenses 4, cylindrical lens array 5.Halogen light source 1 is positioned at the focal position 6 of ellipsoid reflector 2, and slot set 3 is positioned at another focal position 7 of ellipsoid reflector, is positioned at the position of focal plane 8 of Fresnel Lenses 4 simultaneously, and Fresnel Lenses is positioned at the position of focal plane 9 of cylindrical lens array.
Like this, the light that sends from halogen light source 1 is concentrated the energy of light sources through ellipsoid reflector 2, by adjusting the distance of slot set 3, Fresnel Lenses 4 and cylindrical lens array 5, light beam to the light source outgoing carries out angle restriction, make light beam remain on 18 '～40 at the subtended angle of vertical direction ' between, the subtended angle of horizontal direction remains between 40 °～60 °.
The course of work of the present invention: the light that sends from halogen light source 1 among Fig. 1, concentrate the energy of light source through ellipsoid reflector 2, light beam by slot set 3, Fresnel Lenses 4 and 5 pairs of light source outgoing of cylindrical lens array carries out angle restriction, make light beam remain on 18 '～40 at the subtended angle of vertical direction ' between, the subtended angle of horizontal direction remains between 40 °～60 °.
Good effect:
Owing to adopted Fresnel Lenses, cylindrical lens array to be used in combination not only to reach outgoing beam in the horizontal direction with the full and uniform effect of vertical direction but also can guarantee the requirement of shooting angle, utilize the ellipsoid reflector that the loss of energy of light source is reduced, make most concentration of energy at the slit place, can guarantee that like this lamp box outgoing beam is visible and can differentiate the color of light in the certain distance scope.And the brightness height, energy consumption is low, and luminous even, definition is strong.The present invention is simple and reliable for structure, and is workable, can well be applied to carrier-borne indication and flight helps among the system of falling.
Four, description of drawings:
Fig. 1 is a lamp box optical system vertical direction structural representation;
Fig. 2 is a lamp box optical system horizontal direction structural representation;
Five, the specific embodiment:
According to accompanying drawing 1 and Fig. 2, halogen light source 1, ellipsoid reflector 2, slot set 3, Fresnel Lenses 4, cylindrical lens array 5 are installed on the same optical axis.3 light sources that halogen light source 1 adopts horizontal Tile to place.Halogen light source 1 is positioned at the focal position 6 of ellipsoid reflector 2, and slot set 3 is positioned at another focal position 7 of ellipsoid reflector, is positioned at the position of focal plane 8 of Fresnel Lenses 4 simultaneously, and Fresnel Lenses is positioned at the position of focal plane 9 of cylindrical lens array.
The light that sends from halogen light source 1 among Fig. 1 is concentrated the energy of light source through ellipsoid reflector 2, by adjusting the distance of slot set 3, Fresnel Lenses 4 and cylindrical lens array 5, according to designing requirement, light beam to the light source outgoing carries out angle restriction, distance between increase slot set 3 and the Fresnel Lenses 4 reduces the vertical subtended angle of outgoing beam, and reduce the vertical subtended angle that distance between slot set 3 and the Fresnel Lenses 4 increases outgoing beam, make light beam remain on 18 ' ± 2 at the subtended angle of vertical direction '; 30 ' ± 2 '; 40 ' ± 2 ' above three embodiment.
The light that sends from halogen light source 1 among Fig. 2 is concentrated the energy of light source through ellipsoid reflector 2, by slot set 3, the light beam of Fresnel Lenses 4 and 5 pairs of light source outgoing of cylindrical lens array carries out angle restriction, after the angle value of vertical subtended angle is determined, interval between slot set 3 and the Fresnel Lenses 4 has just been decided, at this moment increase the horizontal subtended angle that interval between cylindrical lens array 5 and the Fresnel Lenses 4 reduces outgoing beam, or reduce the horizontal subtended angle that interval between cylindrical lens array 5 and the Fresnel Lenses 4 increases outgoing beam, make light beam subtended angle in the horizontal direction remain on 40 °; 50 °; Between 60 °.More than enumerate three embodiment, can design according to actual needs and debug.
