Description
Technical field
The utility model relates to a kind of lighting apparatus that is applied to video display, stage, refers in particular to a kind of lighting apparatus that possesses novel focusing mode.
Background technology
Be applied to the lighting apparatus of video display, stage etc. at present, light all need be focused to produce a desired effect.This is the necessary technological means that stage performance, movies-making etc. guarantee artistic effect.In this type of traditional lighting apparatus, often all be to adopt focus lamp and light housing relative fixed, through light sources such as mobile illuminators, the distance between light source and the focus lamp is changed, thereby reach the purpose of regulating the light focusing focal length.
As shown in Figure 1, be video display traditional in the prior art, the structure of theatrical luminaire, all comprise light housing 1 ' as the one of which; Be arranged on the condenser lens 2 ' of said light housing 1 ' front end, this condenser lens 2 ' is installed on the lens mount 3 '; Be installed in the focusing axle 4 ' of said light housing 1 ' bottom; The one of which end penetrates the side of light housing 1 ' near condenser lens 2 '; And be fixedly connected with said lens mount 3 ' through alignment pin 5 ', its other end penetrates the relative opposite side of light housing 1 ', and installation focusing knob 6 '; Go up the mounting lamp holder (not shown) at the focusing axle that is positioned at light housing 1 ' inside 4 ', and on this lamp socket, lay illuminator 7 ' (being light source) like osram lamp, dysprosium lamp.Therefore; Can be through focusing knob 6 ' come turns focusing axle 4 '; Making lamp socket drive illuminator 7 ' moves forward and backward at light housing 1 ' inner condenser lens 2 ' relatively; Make the distance between illuminator 7 ' and the condenser lens 2 ' change, thereby realize regulating the purpose of illuminator focal length.
Above-mentioned this traditional focusing mode does not exist what restriction and problem for light relatively illuminator (like osram lamp, dysprosium lamp etc.); But development, progress and variation along with illuminator (light source); Parameters such as its volume and weight all constantly increase; And the specification requirement of illuminator own is increased, the also corresponding increase of its optional equipment, thus make this traditional focusing mode more and more difficult in practice.
At present novel illuminator LED has the demand of heat radiation technically, and promptly the operating temperature of LED is conditional, and the lamp socket temperature of general LED must not surpass 65 ℃, not so gently then cause the luminescent device light decay, and the life-span reduces, and is heavy then may the scaling loss illuminator.Therefore, must be equipped with cooling system 8 ' for the illuminator 7 ' that is placed on the lamp socket.For low-power LED, because power is little, the produced simultaneously heat of its work is low, and heat radiation requires also low, and the less cooling system 8 ' of relative volume can satisfy the heat radiation requirement, so contradiction is not given prominence to restriction.
But for the lighting apparatus that is applied to video display, stage, its illuminator need satisfy powerful requirement, and often the monomer light source just reaches myriawatt power.Although illuminators such as LED possess energy-conservation effect, its luminous efficiency is higher, generally is ten times of tengsten lamp, is quite a few times of dysprosium lamp.But in the lighting demand of video display, stage, still need use the illuminator that possesses several kw of power.And, not only needing the power-supply system 9 ' of larger volume electric energy to be provided during its work to it for the LED of last kw of power, required cooling system 8 ' also must possess larger volume.In order to reach purpose to illuminator LED radiating and cooling, reach its heat dissipation technology index, need dispose several kilograms heat radiation aluminium easily, or more complicated cooling system 8 '.Based on above-mentioned; If still adopt traditional focusing mode; So in the process of focusing, must utilize lamp socket to drive the heavy weight illuminator of the big volume of laying above it 7 ', cooling system 8 ' moves with power-supply system 9 ' simultaneously, this obviously is unrealistic also extremely inconvenience.
For emerging LED illuminator, high-power LED especially, the cooling system of its outfit are to be critical to closing.The cooling system of great power LED does not almost have better other heat dissipation equipments except heat-pipe radiator at present.And heat-pipe radiator has almost occupied the volume and weight of whole lighting apparatus 90%.In order to reach the purpose of focusing, and need to regulate these heavy equipment of moving, waste time and energy, when efficient reduces, also can improve equipment loss.
