Abstract
The present invention provides a non-circular reflective cup, which comprises two same or different light distribution curves. A cup body has a non-circular bottom. Inner wall of the reflective cup is provided with a refection curve surface formed by the combination of a plurality of curve surfaces. When the light is emitted by a light source in the corresponding position of the reflective cup, the light ray is reflected by the reflection curve surface positioned on the inner wall of the reflective cup, and objects are uniformly irradiated by the reflected light ray based on the light distribution curve and the shape for the light irradiated on the objects is non-circular. The combination of a plurality of the reflective cups is used for large area flood lighting, and no fold-over exists between each two reflective cups and the effective area is large.
Description
Technical field
The present invention relates to lighting, especially the area floodlighting reflector of light fixture.
Background technology
At present, area floodlighting adopts a symmetrical distribution curve flux design mostly with the reflector of light fixture, circular configuration is adopted in cup body bottom, when many combinations of this kind reflector apply to area floodlighting, the light shape that the light that light source sent reflects away via reflector all is circular, and it has ghost image between any two, and effective area is little, spacing between any two is shorter, causes the wasting of resources.
Summary of the invention
One object of the present invention is to solve weak point of the prior art, provides a kind of and can produce large tracts of land floodlight effect, and effective area is big, and spacing between any two is big and make full use of the reflector of light source.
For achieving the above object, non-circular reflecting cup of the present invention has two distribution curve fluxs identical or inequality, and cup body bottom is non-circular, and the inwall of reflector is provided with the reflective surface that a plurality of curved surfaces combine.
Described a plurality of curved surface can even or non-homogeneous arrangement.
Described a plurality of curved surface size can be the same or different.
After light source sends light, owing to have two distribution curve fluxs identical or inequality, light is through the reflection of the reflective surface on the reflector inwall, the light reflected angle is all different, increased range of exposures, cup body bottom is non-circular, even via the reflector light reflected, light shape is non-circular, when many combinations of this kind reflector apply to the Lamp cup of area floodlighting, it does not just have ghost image between any two, effective area is big, and spacing between any two is also big, thereby reaches good floodlighting purpose, and have the following advantages: the light energy loss is little, reflective light efficiency height; Reflective radiation direction can be controlled; Light source utilization rate height carries out maximized thrifty to resource.

The specific embodiment
The present invention relates to a kind of bottom is non-circular reflector, and the invention will be further described below in conjunction with accompanying drawing.
With reference to Fig. 1, the top of reflector 1 is provided with installs with cup 2 and light source 3, and its mounting means can be adjusted according to different light sources, is provided with the reflective surface 4 that a plurality of curved surfaces combine on the inwall of reflector 1, a plurality of curved surfaces can even or non-homogeneous arrangement, and size can be the same or different.After light source 3 sent light, light, shone on the illuminated object by distribution curve flux shown in Figure 5 through 4 reflections of the reflective surface on reflector 1 inwall, and distribution curve flux 5 and distribution curve flux 6 can be the same or different.
With reference to Fig. 4, the reflector that the bottom is rounded, light shape after reflection is rounded, when many reflector combinations apply to area floodlighting, do not shine the zone between any two, it just has ghost image between any two, can not make full use of light source, cause the waste of resource.
Fig. 2, Fig. 3 a are an embodiment of the present invention, the reflector that the bottom is square, light after reflection is even, and light shape is square, when many reflector combinations apply to area floodlighting, the zone that it had not only shone between any two but also do not have ghost image, and, when the square length of side in bottom is the same with round diameter, its effective area is bigger than the effective area of the conglobate reflector in bottom, spacing is also big between any two, thereby reaches the purpose that makes full use of light source, has reduced the wasting of resources.
Fig. 3 b is the combined reflected light shape figure of many reflectors of another kind of embodiment of the present invention, triangular in shape bottom itself, light after reflection is even, light shape is triangular in shape, when the combination of many reflectors applies to area floodlighting, the zone that it had not only shone between any two but also do not have ghost image, spacing is also big between any two, thereby reach the purpose that makes full use of light source, reduced the wasting of resources.
Above-mentioned is preferred embodiment of the present invention only, is not to be used for limiting practical range of the present invention.Be that all equivalences of doing according to the content of the present patent application claim change and modification, all should belong to technology category of the present invention.
