Detailed description of the invention
Art work displaying LED shot-light, comprise main body rack 1, be arranged on shot-light body on main body rack 1 and supporting power supply 3, shot-light body and main body rack 1 form and are rotationally connected by rotating shaft 4, shot-light body comprises shell, LED light source 10 and lens devices is in the enclosure installed, be fixed on the front of LED light source 10 by convex lens support 2 along light emission direction lens devices, key is: the front at lens devices is also provided with fly's-eye lens 5, and fly's-eye lens 5 arranges in the enclosure by fly's-eye lens bracing frame 6.
Described fly's-eye lens 5 is demountable structure on fly's-eye lens bracing frame 6, and has been provided with the fly's-eye lens retainer ring 7 of sealing role in the termination of fly's-eye lens bracing frame 6, fly's-eye lens retainer ring 7 with fly's-eye lens bracing frame 6 for being threaded.Increase conveniently replaced fly's-eye lens device at LED light source 10 front ends, different hot spots needs different fly's-eye lenses 5, and fly's-eye lens retainer ring 7 covers fly's-eye lens 5 for fixing and encapsulation.Change fly's-eye lens 5 time operation very simple, only fly's-eye lens retainer ring 7 need to be backed out.Change fly's-eye lens and need indispensable condition:
A, client specify spot size, and light fixture is to gallery shadow surface distance.
B, optical design teacher are according to customer requirement optical design fly's-eye lens.
C, fly's-eye lens compacting.
D, people adopt the both hands of oneself that fly's-eye lens old light fixture is pulled down, newer fly's-eye lens is replaced with.
Described shell comprises base 8 and rotating cylinder 9, and rotating cylinder 9 is rotational structure on base 8, and LED light source 10 is fixed on base 8, and fly's-eye lens bracing frame 6 forms sliding extension structure with the inwall of rotating cylinder 9.The rotation of rotating cylinder 9 and telescopic process, can drive the rotation of fly's-eye lens 5, and adjust the distance of fly's-eye lens 5 and lens devices and LED light source 10, thereby realize adjusting focal length so that light is even and concentrated.
Described lens devices is two-lens structure, comprises that the first convex lens 11 and the second convex lens 12, the first convex lens 11 and the second convex lens 12, for location, front and back arranges, are separately fixed on convex lens support 2.For difformity and the size of the art work, by the rotation adjustment of the first convex lens 11 and the second convex lens 12, can increase lens the light of projection is carried out to shape adjustments.
On described main body rack 1, be also provided with human body sensing device 13.Can reach people near the art work, light is lighted gradually, and in the time that people is before showpiece, illumination keeps, when people's light of leaving away extinguishes gradually.
The theoretical foundation of fly's-eye lens optical design: the principle of desirable illuminator latitude of emulsion conservation.Latitude of emulsion E=π Ssin2 θ, wherein, S is light-emitting area, and θ is the angle of divergence, and when the known angle of divergence when hot spot increases, lighting area can reduce, and hot spot is more concentrated, and brightness is higher.So when fly eye lens array number increases, reduce after each lenticular size, illumination hot spot brightness increases, but the angle of divergence also increased, and lighting area can reduce.
Key of the present utility model be increase fly's-eye lens 5, the each lenslet in fly's-eye lens 5 by lenslet overlapping imaging corresponding first row fly's-eye lens on illuminated area.Referring to the fly's-eye lens index path of Fig. 3, because the whole angle pencil of ray of light source is divided into multiple light pencil illuminations by first row compound eye, and the small inhomogeneities within the scope of each light pencil is due to the mutual stack in symmetric position light pencil, make the small inhomogeneities of light pencil obtain compensation, thereby the light energy in whole aperture is utilized effectively and uniformly.Be gathered in lighting screen by condenser from the hot spot of fly's-eye lens 5 outgoing, on lighting screen, the every bit of hot spot is all subject to the irradiation that light source sends a little, simultaneously, the light beam that on LED light source 10, every bit sends again all intersection overlap onto in the same field range of illumination on hot spot, so obtain a uniform hot spot.Effect please refer to Fig. 4.
While adds the first convex lens 11 and the second convex lens 12 before the lamp pearl of the LED light source 10 of shot-light, convex lens project for the luminous energy of LED is converged to backward fly's-eye lens 5, please refer to the schematic diagram of Fig. 5, sensitive surface is plane, exiting surface is free form surface, convex lens there is no the distance between fixing parameter or fixing and LED light source, as long as diagram lens similar structures, all meet this product principle of luminosity.
