The invention discloses a uniform-illumination reflecting cup. The reflecting cup is provided with a cup body which is formed by connecting and arranging at least three planar reflecting plates in turn in a circle, wherein the diameter of the front end of the cup body is greater than that of the back end of the cup body. The uniform-illumination reflecting cup provided by the invention has uniform light distribution effect and high lamp illumination efficiency and adapts to point light sources and surface light sources.
Description
Technical field
The invention belongs to field of illumination lamp technology, relate to a kind of light fixture reflector, relate in particular to the even reflector of a kind of illumination.
Background technology
At present, the reflector that various Down lamp adopted on the market mainly is smooth parabolic type, and employed light source is also varied, and wherein the light source of dusting Metal halogen lamp, electricity-saving lamp, electrodeless florescent lamp can be regarded area source as, so light distribution effect is more even, but the light fixture light efficiency is not high; Also having a kind of is to make light source with transparent Metal halogen lamp, because of its luminous component smaller, can be similar to and regard spot light as, its illuminance uniformity is poor, center illumination is lower, needs to wait such as frosted, tangerine peel to reach the even effect of luminous intensity distribution by changing the reflector inner surface treatment, but this processing back light efficiency reduces, and brightness is not enough.
Summary of the invention
The technical problem to be solved in the present invention is, at the above-mentioned defective of prior art, provide a kind of light distribution effect evenly, the even reflector of illumination of light fixture light efficiency height, simultaneous adaptation spot light and area source.
The technical solution adopted for the present invention to solve the technical problems is: the even reflector of a kind of illumination, and join successively by at least three plane reflectors and to arrange the cup that a circle forms, described cup point diameter is greater than the rear end diameter.
Described plane reflector is trapezoidal, and the cup diameter that the plane reflector is formed begins forward end by rear end face and progressively enlarges.
Described cup comprises at least two wall of cups that join of joint, and every joint wall of cup is joined successively by three plane reflectors at least and arranges a circle and forms, and the adjacent two angle α that save between the wall of cups are not more than 180 °.
The wall of cup foremost of described cup is the first segment wall of cup, and the first segment wall of cup is parallel with the reflector axis, and any joint wall of cup behind the first segment wall of cup and the angle of reflector axis are all less than the wall of cup of its front adjacent segments and the angle of reflector axis.
Be seamless link between the adjacent plane reflector.
Described cup is that the punching press shaping forms again by the plane reflector elder generation spinning of an integral body.
All plane reflector shapes in described every joint wall of cup are identical.
Described plane reflector adopts highly reflective material to make.
The present invention adopts the broken line type reflector of being made up of a plurality of planes reflector, its profile is different from traditional reflector parabolic type, the light that light source sends carries out mixed light after a plurality of facet reflector reflections, thereby reaches the effect of even light, has also improved the light fixture light efficiency simultaneously.The present invention is not only applicable to dusting Metal halogen lamp, electricity-saving lamp, electrodeless florescent lamp and transparent Metal halogen lamp, is applicable to other similar light source yet.
The present invention adopts two joints or the wall of cup more than two joints to form at cup, and the light of light source obtains the reflection of different angles as much as possible, and mixed light is more even.
In order to improve light efficiency, avoid the secondary of light even repeatedly reflection as far as possible, angle during design between the wall of cup of the joint number of the quantity of every joint wall of cup midplane reflector, cup and adjacent different joints will meet the demands: first segment wall of cup foremost is parallel with the reflector axis, and any joint wall of cup behind the first segment wall of cup and the angle of reflector axis are all less than the wall of cup of its front adjacent segments and the angle of reflector axis.
Described cup is that the punching press shaping forms again, avoids splicing between the Different Plane luminous plaque loss in the light reflection that causes in the slit by the plane reflector elder generation spinning of an integral body, and maximum possible improves light efficiency.

The specific embodiment
In order to narrate conveniently, the present invention is defined as front end with the cup opening maximum of reflector, and the location definition that light source is installed is the rear end.This definition is all deferred in the statement of all concerned directions in the file.
As shown in Figure 1, 2, the even reflector of a kind of illumination is joined successively by at least three plane reflectors 10 and to arrange the cup that a circle forms, and the cup diameter that plane reflector 10 is formed is begun progressively to enlarge by the rear end face of installation light source.In order to reach the uniform purpose of luminous intensity distribution, cup comprises at least two wall of cups that join of joint, and every joint wall of cup is joined successively by three plane reflectors 10 at least and arranges a circle and form, and reflector is exactly to be made up of M * N plane reflector like this, wherein N is a joint number, and M is the quantity of every joint midplane reflector.The present invention is divided into NXM part with the light of light source by reflector, carries out mixed light, finally reaches the effect of sparing light by the angle a that adjusts between each joint of reflector again.Because N is big more, half light intensity angle is big more, central light strength diminishes, and M is big more, and half light intensity angle is more little, it is big that central light strength becomes, therefore will be by increasing central light strength and carrying out the purpose that mixed light reaches uniform light distribution with the light that does not carry out secondary light-distribution, N selects can not be too big, preferred two～five joints, the selection of M can not be too little, preferred 8～20.The wall of cup foremost of cup is the first segment wall of cup, and the first segment wall of cup is parallel with the reflector axis, and any joint wall of cup behind the first segment wall of cup and the angle of reflector axis are all less than the wall of cup of its front adjacent segments and the angle of reflector axis.N gets 2 in the present embodiment, adopts two joint wall of cups, and the quantity M of every joint wall of cup midplane reflector is 10.
Described plane reflector 10 is trapezoidal, and all plane reflector 10 shapes in every joint wall of cup are identical, are seamless link between the adjacent planar luminous plaque 10, in order to accomplish seamless link, cup is the plane reflector elder generation spinning by an integral body, and the punching press shaping forms again.In order to realize the high reflectance of reflector, high reflectance materials such as plane reflector 10 employing rafifinals are made.
As shown in Figure 3, it is the light reflection case schematic diagram of the embodiment of the invention, as can be seen from the figure: through different plane reflector reflections, reflector converges to the center with the reflection of light source rim ray, central light strength is strengthened, by carrying out mixed light, thereby reach uniform light distribution with the light that does not carry out secondary light-distribution.
Be the distribution curve flux figure of the embodiment of the invention as shown in Figure 4, Fig. 5 is the distribution curve flux of parabola shaped reflector.As seen from Figure 4: the light through reflector reflection of the present invention is more concentrated, and the uniformity is higher.Uniformity of illuminance can be expressed as the ratio of minimal illumination and maximal illumination in the certain limit.Distribution curve flux minimal illumination and ratio of maximal illumination in 30 degree scopes is about 90% as can be seen from Figure 4, compares with the ratio of maximal illumination about 20% with Fig. 5 minimal illumination, and illuminance uniformity has obviously improved.
