Detailed description of the invention
In order to further illustrate principle of the present invention and structure, existing by reference to the accompanying drawings to a preferred embodiment of the present invention will be described in detail.
The fitting structure of the adjustable light efficiency in the present embodiment as shown in Figure 1, they some LED light sources comprising a base, a reflector, a light source base and be arranged on light source base.
As shown in Figure 2, reflector 2 comprises a circular top plate 21, and the periphery of circular top plate 21 extends to form a sidewall 22 downwards, and sidewall 22 is the taper tubular structure that downward diameter increases gradually.The bottom of sidewall 22 extends radially outwardly the main light-reflecting portion 23 of formation one, and the outward flange of main light-reflecting portion 23 extends to form a skirt section 24 downwards; The bending place adjacent with main light-reflecting portion 23 at sidewall 22 extends to form an internal thread ring 26 downwards, and internal thread ring 26 has female thread structure.It can also be seen that by figure, sidewall 22 is also provided with several printing opacity lattice 25, is specially 8,8 printing opacity lattice 25 are along the circumferential direction evenly arranged on sidewall 22, and each printing opacity lattice 25 are the microscler through hole along sidewall 22 bearing of trend.Obviously, printing opacity lattice 25 are positioned at above main light-reflecting portion 23.The outer surface of reflector 2 is all have better reflexive reflective surface, and wherein the upper surface of main light-reflecting portion 23 is main reflective surface, and the outer surface of sidewall 22 is time reflective surface.In the present embodiment main reflective surface and reflector 2 axis between angle theta be less than 90 degree, the angle theta namely between main light-reflecting portion 23 and the axis of reflector 2 is less than 90 degree.Angle theta between the axis of main reflective surface and reflector 2 can affect the spot condition of light fixture irradiation light, therefore can regulate the size of θ according to the needs of practical application.
As shown in Figure 2, in the present embodiment, base 1 and light source base 3 are integral structures.Base 1 comprises an annular bottom plate 11, the inward flange of base plate 11 upwards extends to form light source base 3, as can be seen from Figure, the sidewall 22 of the similar reflector 2 of light source base 3 is also the taper tubular structure that a downward diameter increases gradually, is structures of a dull and stereotyped sealing on the top of light source base 3.Be provided with an external screw thread ring 4 in the bottom outside of light source base 3, this external screw thread ring is as reflector installation portion, and it has external thread structure., as shown in Figure 3, on the external thread structure of external screw thread ring 4 and reflector 2, the female thread structure of internal thread ring 26 cooperatively interacts.
In addition, extend to form a location division 12 up and down near base plate 11 outer edge, the base plate 11 outside location division 12 is set to installation portion 111; Base plate 11 is provided with cable-through hole 13.
LED light source 5 is fixed on light source base 3, and the outside of the light source base 3 corresponding with each printing opacity lattice 25 position is all amplexiformed and is fixed with a LED light source 5.
The light fixture of the adjustable light efficiency of the present embodiment also comprises a housing 6, and this housing 6 is a tubular structure, and its upper opening place is equiped with a Transparent Parts 7.In housing 6, side-lower is provided with the draw-in groove of an annular, and the installation portion 111 on floor 11 can be installed on wherein by this draw-in groove, thus is fixed in housing 6 by base 1.The below of housing 6 is closing in shapes, and last formation one can be used for the cable-through hole of wiring.
During light fixture work, fixing indirectly by thread connecting mode and light source base 3 of reflector 2, in time regulating the cooperation button number of screw thread, i.e. the distance of adjustable LED light source 5 and main reflective surface and the angle with main reflective surface, the mode making it throw light on can be changed by between optically focused and floodlight.Regulate the difference that can also have influence on irradiation brightness (illumination) when the cooperation button number of screw thread, the size also by regulating LED light source 5 to expose the printing opacity lattice 25 of reflector 2, realizes the adjustment of illumination efficiency simultaneously.
Certainly, for ensureing the normal work of light fixture, the overall dimensions of light source base 3 and LED light source 5 that LED light source 5 place is housed should be less than the size of the reflector 2 of corresponding position, and like this when rotating reflector 2, the sidewall 22 of reflector 2 can not cause damage to LED light source 5 in scratching.
These are only better possible embodiments of the present invention, not limit the scope of the invention, all utilizations description of the present invention and the change of the equivalent structure done by accompanying drawing content, be all included in protection scope of the present invention.
