The specific embodiment
For principle and the structure that further specifies the utility model, combine accompanying drawing that the preferred embodiment of the utility model is elaborated at present.
See also Fig. 1 to shown in Figure 5, the reflex reflector of the utility model comprises a base plate 1 and is connected a plurality of reflective side walls 2 on the said base plate 1 that said base plate 1 surrounds with said reflective side walls 2 and forms the cup body structure that an opening 3 makes progress.Said base plate 1 and said reflective side walls 2 can be selected the specular aluminium material bending spicing forming type of high reflectance for use; The minute surface of said specular aluminium is towards the inboard of cup; The material thickness that said specular aluminium is selected for use is generally 0.2mm～2mm and does not wait; Specifically can select 0.3mm, the reflecting rate of this specular aluminium material can reach more than 95%.
Said reflective side walls 2 the limit number of quantity corresponding to the polygonized structure of said base plate 1 be set; So that said a plurality of reflective side walls 2 can be connected the outer edge of said base plate 1 adaptedly; Correspondingly, surround the opening 3 that forms by the top of said a plurality of reflective side walls 2 on the cup body structure and also be polygonal-shaped openings.Said a plurality of reflective side walls 2 is provided with in pairs, and two reflective side walls, the 2 relative base plate centers in the every pair of reflective side walls 2 are symmetrical distribution, and each to the size of reflective side walls 2 can be identical also can be different.Each reflective side walls 2 comprises a first order reflection face 21 and secondary reflex face 22 that connects up and down towards the inner side of cup.The top of said reflective side walls 2 also can be provided with to the level bending extension of the cup outside to be used for the flanging 23 that the mount reflex reflector is used.
Concrete to the embodiment among Fig. 1 to Fig. 4; The quantity that is provided with of said reflective side walls 2 is two pairs; Be respectively a pair of first reflective side walls 2A and a pair of second reflective side walls 2B; And reflective side walls 2A is different with the size of reflective side walls 2B; The opening 3 of said cup body structure is a rectangular aperture, and the said first reflective side walls 2A comprises a secondary reflex face 22A and first order reflection face 21A who connects up and down, and the top of said secondary reflex face 22A is provided with the flanging 23A that extends to the level bending of the cup outside.The said second reflective side walls 2B comprises a first order reflection face 21B and secondary reflex face 22B who connects up and down, and the top of said secondary reflex face 22B is provided with the flanging 23B that extends to the level bending of the cup outside.
Said first order reflection face 21A/21B and said secondary reflex face 22A/22B are flat surface; Said first order reflection face 21A/21B and said base plate 1, said first order reflection face 21A and said secondary reflex face 22A and said first order reflection face 21B and said secondary reflex face 22B constitute certain degree respectively; Focus on and correct in position, size and the angular range set with light that the light source in the cup is sent, the principle that light that the light-emitting device of present embodiment sends light source focuses on and corrects is described below in conjunction with the reflective principle schematic of the reflex reflector of Fig. 5:
Light source in the said reflex reflector is a led light source, and the illuminator of this led light source is that colloid is the cylindrical LED of φ 5, and luminescent wafer is that face is luminous, and the light that is sent is the 180 ° of distributions in space, and this led light source is installed in the hole 11 on the said base plate 1.When said led light source is luminous; Light is with the 180 ° of distributions in space; Because the upper surface of the base plate 1 of the luminescent wafer of LED and reflex reflector is in sustained height, and this luminescent wafer is positioned on the optical axis of LED, and optical axis overlaps with the axis of reflex reflector; So the upper surface of the base plate 1 of reflex reflector and the intersection point of axis just become 180 ° of luminous light source points.
The size of two pairs of reflective side walls 2 in the present embodiment is different; Wherein the vertical range of the top of the first reflective side walls 2A to said base plate 1 is 7.1mm; The vertical range of the top of the second reflective side walls 2B to said base plate 1 is 10.3mm; And; 1 one-tenth 118 ° of angle of the first order reflection face 21A of the said first reflective side walls 2A and said base plate; The first order reflection face 21A of the said first reflective side walls 2A becomes 161 ° of angles with the secondary reflex face 22A of the said first reflective side walls 2A, 1 one-tenth 115.5 ° of angle of the first order reflection face 21B of the said second reflective side walls 2B and said base plate, and the first order reflection face 21B of the said second reflective side walls 2B becomes 170.5 ° of angles with the secondary reflex face 22B of the said second reflective side walls 2B.At this moment; The formed angle theta of top margin of light source point to the two first reflective side walls 2A is 72 °; The formed angle β of the top margin of light source point to the two second reflective side walls 2A is 58 °; The light that above-mentioned led light source sent can form one 72 ° * 58 ° hot spot in the rectangular aperture scope of light-emitting device; And 72 ° * 58 ° extraneous light almost nondestructively is reflected away through said first order reflection face 21A/21B and said secondary reflex face 22A/22B, and via the focusing of said opening 3 with correct in the light area that has evenly added to 72 ° * 58 °, so realized the even high effect of light source.
In addition; What a bit need supplementary notes in addition is; Formed angle numerical value can proportional amplification or dwindle between formed angle numerical value and said first reflective side walls and said second reflective side walls between distance, said the first/the second reflective side walls and the said base plate of said base plate for said the first/the second reflective side walls; This amplification or dwindle the function that can not influence reflex reflector; And can also be through the shape of adjusting said base plate 1, the angle that quantity and said first order reflection face 21 and said secondary reflex face 22 are set of said reflective side walls 2 and shape and the size that formed opening 3 is controlled in splicing; Thereby size, shape and the angle of control and adjustment hot spot, the light that also can control and adjust reflection drops on which position of hot spot, thereby reaches the illumination effect of uniform better.
The reflex reflector of the utility model can produce high light efficiency, the uniform hot spot of illumination after cooperating light source; Further also can adjust position, size, shape and the angle of hot spot through the splicing angle of adjustment first order reflection face and secondary reflex face, and simple in structure, the advantages of small volume of this reflex reflector, can produce fast, assemble easily, cost is low.
Yet; The above is merely the preferable possible embodiments of the utility model; And the protection domain of unrestricted the utility model, so the equivalent structure that all utilization the utility model specifications and accompanying drawing content have been done changes, all be included in the protection domain of the utility model.
