The specific embodiment
With reference to figure 1 and Fig. 2, this reflecting LED ground bank light comprises lamp body main body 1, carriage 5, is installed in the light source portion on the carriage, the circuit board 13 that is electrically connected with light source portion, radiating part and power supply 8.
Lamp body main body 1 is the metal framework, is roughly L shaped plate stamping spare.Show among Fig. 2 that the L shaped plate of lamp body main body becomes the backboard and the base plate of ground bank light.The backboard upper end forms the reflex part parallel with base plate.On reflex part and the base plate respectively punching press a plurality of louvres are arranged.
Light source portion specifically comprises led light source 15, substrate 14, reflector 2, side reflector 3.Wherein, reflector 2 and two side reflectors 3 are combined into reflex reflector.Side reflector 3 can be integrally formed with reflector 2, is collectively referred to as reflector 2.Light source 15 is that plurality of LEDs is horizontal in equidistant mode, vertically is embedded in the substrate 14.And the head of LED is towards reflector, perpendicular to substrate.Reflector is the suitable arc of arranging with led light source 15 of length.One side straight flange of arc is connected with the base of substrate, and the head that makes LED is between substrate and reflector, and towards reflector.Only be appreciated that to need substrate is fixed on the reflector to get final product, do not need as present embodiment the straight flange of reflector is connected with the base of substrate.
Be provided with two side reflectors 3 in the both sides of reflector 2, form reflector jointly with reflector with the plane at the edge identical with the reflector arc.Reflector is identical with the side reflector material, and its surface towards light source becomes reflective surface.Can be by reflective surface be carried out specially treated, as adhere to optical material (as fluorescent material), minute surface polishing etc.; Also can improve light reflectivity by selecting the reflector of material for use with high reflectance.
The position of led light source 15 in reflector makes the LED reverberation be reflected to can access uniform asymmetric light field on the illuminated object.Reflector 2 is made according to particular curve, is preferably arc, but is not limited thereto, and for example is that asymmetrical ballistic-shaped etc. all can.So long as by optical computing, the light of reflective surface reflection is projected to access uniform asymmetric light field on the illuminated object just passable.
Carriage 5 is supports of inverted concave, is used to connect lamp body main body 1, reflector 2, two side reflectors 3 and two side plates 4.The peristome of the support of inverted concave is fixed on the both sides of substrate 14 and is fixed on the base plate, the vertical portion couples together side reflector 3 and side plate 4 respectively, and horizontal part is fixed together with the mode that slightly exceeds side plate 4 and reflector 2 reflex part (part parallel with base plate) with reflector 2 and backboard.In the present embodiment, the peristome of carriage 5 by metallic power cover 7 indirect securement to base plate.The peristome of carriage 5 also can directly be installed on the base plate, even also can carriage and lamp body main body 1 is one-body molded.
Between the backboard of reflector 2 and lamp body main body 1, circuit board 13 is set.Circuit board 13 is electrically connected with led light source 15, is switched on or switched off to control it.
Power bay 9 is arranged on the top of base plate and in the place ahead of carriage 5 (away from the direction of backboard), is used for support level power supply 8 thereon.Power supply 8 is electrically connected with led light source 15, is its power supply.
Be embedded in the heat that the led light source 15 in the substrate 14 sends, come out by substrate 14.In order to accelerate the heat radiation of substrate 14, penetrating the opposite side (being the place ahead) of directions with led light source 15 in Fig. 2 radiator 12 be sticked at substrate away from a side of reflector 2.Radiator 12 is aluminum fins, can keep the good heat radiating of LED.
Being fixed on air duct 11 on carriage 5 bottoms and the side plate 4 in the mode that coats radiator 12, is the L shaped metalwork in spill cross section.Form the air channel between radiator 12 and air duct 11, and also form the air channel between air duct 11 and side plate 4, two air channels connect.And, on two side plates 4, offer ventilating opening respectively, connect with the air channel.Tail end near side plate 4 on air duct 11 is equipped with blower fan 6, and blowing is to strengthen ventilation and heat in L type air channel.
The end face of substrate top side, air duct end face and power supply cover is roughly on same plane.The bottom side of substrate is connected with the bottom side of reflector, that is, led light source 15 is positioned at the top of the bottom side of reflector, is higher than the position of the bottom side of reflector, among Fig. 2 between the upper and lower sides of reflector.
The centre bit of the floor below of lamp body main body 1 is equipped with adjusting knob, can regulate the luffing angle of light fixture.
As shown in Figure 3, the present invention utilizes light reflection principle, and led light source 15 is radiated in asymmetric curved reflector 2 concave surfaces, can strengthen intensity of reflected light through reflection.For example in the distance canopy of the heavens 2 meters the time, the illumination of bank light (1250W) is 720Lx traditionally, and the illumination of this reflecting LED ground bank light (200W) is 480Lx.Reflecting LED ground bank light is (MO) 2 meters apart from the canopy of the heavens, can reflex to 6 meters of canopy of the heavens height (ON) from ground level.Therefore, under the situation of the identical angle of pitch, this reflecting LED ground bank light can enlarge on the stage the bank light range of exposures.
The line source that the present invention adopts single LED to form shines in the reflector 2.Utilize light reflection principle, shine illuminated object after the reflection, can make not direct irradiation photographed object of light source, lamp light source does not have direct light, can prevent to dazzle the eyes, dazzling, helps the stage performance.Reflector becomes asymmetric arc, and led light source is radiated at the reflector ad-hoc location, reflects to form asymmetric light field through reflector, impinges upon to make far and near distance light soft evenly on the illuminated object, and stage effect is good.
In one embodiment of the invention, reflecting LED ground bank light (200W) total light flux 3600Lm, bank light (1250W) total light flux 6900Lm traditionally, the total light flux of reflecting LED ground bank light be higher than bank light (1250W) traditionally total light flux 1/2.1/2 of bank light power is 625W traditionally, and the power of this reflecting LED ground bank light is 200W, thus energy savings, the light efficiency height.The lamp body mean temperature of reflecting LED ground bank light is 35 ℃, reduces by 2/3 than traditional halogen tungsten light-source temperature, the light fixture long service life.In addition, because the special radiator structure that adopts, this reflecting LED ground bank light can not produce burning heat sensation, meets the needs of stage performance.
More than reflecting LED provided by the present invention ground bank light is had been described in detail, but obvious specific implementation form of the present invention is not limited thereto.For the those skilled in the art in present technique field, the various conspicuous change of under the situation that does not deviate from claim scope of the present invention it being carried out is all within protection scope of the present invention.
