?
[background technology]
At present, the most ripe technology of operation shadowless lamp is overall reflective formula halogen shadowless lamp, be characterized in Stability Analysis of Structures, safeguard that efficient and convenient, light spot shape is mellow and full evenly, the light beam degree of depth is large, color reducibility is excellent, but be subject to the defective effect of halogen light source own, light source life is short, power consumption is large, luminous efficiency is low etc., has substituted trend gradually.In recent years, along with the development of LED technology, the application of LED technology on operation shadowless lamp is also with the fastest developing speed, adopt LED as the feature of light emitting source be that light source life overlength, energy-conservation, colour temperature are convenient to control, direct current is without stroboscopic, infrared without ultraviolet.Due to many excellent specific properties of LED lamp, so LED lamp is the inexorable trend of operation shadowless lamp development as operation shadowless lamp new light sources.
But due to prior art restriction, single single-chip LED also cannot accomplish the intensity of illumination being equal to mutually with the conventional light source such as Halogen lamp LED, be that matrix form is arranged LED so LED operation shadowless lamp lamp holder generally adopts at present, synthesize required without shadow effect.There is following shortcoming:
1, development and Design difficulty: due to LED One's name is legion, for LED arrange, control, coordination, circuit layout protection be all complex engineering.
2, structural manufacturing process difficulty: inside, each LED unit, needs precision architecture to meet required to reach light path; Between each unit, need the coordinating and unifying, the complexity to structure and processability require very high; Constructional device is a lot, requires very high in case affect whole structure on device reliability.
3, installation and maintenance difficulty: even if adopt modularization to produce, also need to regulate the each unit of confirmation.When fault occurs, investigation is also very complicated one by one.
4, hot spot is not round, the light beam degree of depth is low: project projection surface with several luminescence units, when all luminescence units overlap a position, more mellow and fuller hot spot just appears in this position; All the other each positions or when overlapping, all there will be plum blossom-shaped hot spot in various degree or disperse spot, when shelter appears in the middle of light path, there will be multiple image.
[summary of the invention]
The present invention is in order to solve the above-mentioned deficiency of prior art, a kind of overall reflective LED lamp cap device is provided and utilized the shadowless lamp of this device.
Above-mentioned purpose of the present invention realizes by following technical scheme: a kind of overall reflective LED lamp cap device and utilize the shadowless lamp of this device, comprises lamp holder interior light-emitting device, multiple reflections condenser system.It is characterized in that: in described lamp holder, be provided with parabolic mirror, parabolic mirror top is provided with heat abstractor, heat abstractor is connected and fixed light source base, in light source base, fix super-high-power LED light source and reflecting and condensing device (inner conical surface), under reflecting and condensing device, be provided with male cone (strobilus masculinus) reflector, described male cone (strobilus masculinus) reflector is connected with shadow shield and Reflective regulation device, and Reflective regulation device is connected with sterile handle.
Described reflecting and condensing device is inner conical surface reflector or convex lens.
Described conical reflecting device is for utilizing male cone (strobilus masculinus) reflection ray.
Described conical reflecting device is connected with shadow shield.
Described heat abstractor is made up of aluminium section bar.
The present invention's advantage is compared with prior art: the present invention adopts single super-high-power LED integrated chip as light source, makes full use of headroom and strengthens radiating effect; Hot spot regulates part without any light source and energy-dissipating device, improves reliability and the safety in utilization of light source; Single LEDs circuit and control circuit are simple, are easy to control and safeguard, reliability is large; Retain to greatest extent when utilizing the plurality of advantages of overall reflective formula shadowless lamp, replace its conventional light source with LED, make it possess the advantage of overall reflective formula shadowless lamp and LED simultaneously

[specific embodiment]
Below in conjunction with accompanying drawing, the present invention is described in further detail:
As Fig. 1, shown in Fig. 2, a kind of overall reflective LED lamp cap device and utilize the shadowless lamp of this device, comprise lamp housing 1, lamp housing 1 connects sterile handle 9, in described lamp housing 1, be provided with parabolic mirror 2, parabolic mirror 2 tops are fixed with heat abstractor 3, heat abstractor 3 is connected and fixed light source base 4, in light source base 4, fix super-high-power LED light source 5, described super-high-power LED light source 5 adopts LED lamp pearl or the integrated lamp bulb of single 30-80W, integral installation is in light source base 4, auxiliary and large area heat abstractor 3, the air that heat reaches between lamp housing 1 and parabolic mirror 2 by heat abstractor 3 reaches shell 1 again, reflecting condensation system 6 is positioned under LED light source, divergent rays is collected and is projected on conical reflecting device 7, the male cone (strobilus masculinus) of conical reflecting device 7 is projected to divergence of beam on parabolic mirror 2 again, Reflective regulation system 9 drives conical reflecting device 7 to do upper and lower displacement along optical axis, thereby change light reflection path, light, after parabolic mirror 2 overall reflective, can form effective light spot and the longer light beam degree of depth in 1m place below lamp holder, the effect of shadow shield 8 is to block direct projection light and other the issuable veiling glare, remaining light that light source produces, in case operator's eyesight is caused and disturbed or infringement.
