Description
Technical field
The utility model relates to LED lighting field, relates in particular to a kind of lens that can uniform mixed light; The utility model also relates to a kind of LED light fixture.
Background technology
Along with improving constantly of the consciousness of energy-conserving and environment-protective, LED light fixture because its light efficiency is high, advantage is more and more the subject to people's such as little power consumption, life-span be long favor, more because its outstanding light modulation toning ability, LED light fixture has become the main source of room lighting gradually.In prior art, LED light fixture etc. adopt many eyelens mostly, are limited to the structure of this lens, the too many LED light source of cannot arranging in same light fixture; Meanwhile, when colour temperature regulates, light is all only through a colour mixture, and the hot spot color homogeneity mixing out is in this way very poor, cannot reach indoor accent light and wash the effect of wall requirement; In addition, use this many eyelens, each specifications and models all must be opened a lens mould, can cause the significant wastage of resource.
Utility model content
In order to overcome the deficiencies in the prior art, the utility model provides a kind of lens that can uniform mixed light, and the utility model also provides a kind of LED light fixture.
The utility model solves the technical scheme that its technical problem adopts:
Lens that can uniform mixed light, one side is provided with annular protrusion, and projection is provided with the end face relative with side, what connect side and end face is two cambered surfaces, be respectively the first cambered surface and the second cambered surface, end face is provided with the annular mixed light chamber to lower recess, and the bottom surface in mixed light chamber is the 3rd cambered surface.
As the further improved procedure of such scheme, the first cambered surface is outside outstanding cambered surface.
As the further improved procedure of such scheme, the first cambered surface is the cambered surface caving inward.
As the further improved procedure of such scheme, the second cambered surface is outside outstanding cambered surface.
As the further improved procedure of such scheme, the second cambered surface is the cambered surface caving inward.
As the further improved procedure of such scheme, the 3rd cambered surface is outside outstanding cambered surface.
As the further improved procedure of such scheme, the 3rd cambered surface is the cambered surface caving inward.
A LED light fixture, comprises LED light source and above-mentioned lens, and LED light source is distributed in mixed light chamber ringwise.
As the further improved procedure of such scheme, LED light source is the combination that is no less than the light source of two kinds.
As the further improved procedure of such scheme, LED light source intersects evenly arranges.
The beneficial effects of the utility model are: by annular mixed light chamber is set on lens, LED light source is contained in mixed light chamber, so both can make light carry out secondary mixed light, thereby reach the even effect of hot spot, again can be with the LED light source of the adaptive varying number of lens, avoid the mode of production of mirror one mould, reduced the design cost of lens.

The specific embodiment
Below with reference to embodiment and accompanying drawing, the technique effect of design of the present utility model, concrete structure and generation is clearly and completely described, to understand fully the purpose of this utility model, scheme and effect.It should be noted that, in the situation that not conflicting, embodiment and the feature in embodiment in the application can combine mutually.
It should be noted that, if no special instructions, when a certain feature is called as " fixing ", " connection " in another feature, it can directly be fixed, be connected in another feature, also can indirectly fix, be connected in another feature.In addition the descriptions such as upper and lower, left and right of using in the utility model, are only the mutual alignment relation of each part of the utility model in accompanying drawing.
In addition, unless otherwise defined, all technology of using are herein identical with the implication that those skilled in the art understand conventionally with scientific terminology.The term using in description is herein in order to describe specific embodiment, rather than in order to limit the utility model.Term as used herein " and/or " comprise the combination arbitrarily of one or more relevant Listed Items.
With reference to Fig. 1, Fig. 2, show an embodiment of the utility model lens.The main body of lens 10 is preferably disc-shaped, and it is divided into upper side 104 and downside 105, and wherein upper side 104 is the exiting surface of LED lens.Downside 105 is provided with the projection of a ring shape, and projection is provided with the end face 106 relative with downside 105, and the two sides that connect end face 106 and downside 105 are cambered surface, are respectively the first cambered surface 101 and the second cambered surface 102; On end face, be also provided with the mixed light chamber to lower recess, bottom surface, mixed light chamber is also cambered surface, i.e. the 3rd cambered surface 103.
The first cambered surface 101 can be outside outstanding cambered surface, can be also the cambered surface caving inward, preferred, is outside outstanding cambered surface, and in addition, the curvature of the first cambered surface 101 can equate everywhere, i.e. sphere also can be not exclusively equal, i.e. free form surface.Similarly, also have the second cambered surface 102 and the 3rd cambered surface 103.
With reference to Fig. 3, Fig. 4, show an embodiment of the utility model LED light fixture.LED light fixture comprises lens 10, pcb board 20, power supply 30 and shell 40, lens 10 are placed in the top of shell 40 and by its covering, lens 10 belows are provided with pcb board 20, pcb board 20 surfaces are provided with some LED light sources that distribute ringwise, it can be the light source of 2700K and two kinds of colour temperatures of 6500K, also can be the light source of two or more other colour temperatures, the staggered below, mixed light chamber that is evenly distributed on of LED light source, the LED light source of varying number can share lens 10, only needs to adjust the spacing between light source.
LED light source can send the light of approximate bright rich distribution after switching on power, these light in annular mixed light chamber after a mixed light effect side and the 3rd cambered surface 103 from mixed light chamber incide lens inside, part light directly reflects from upper side 104, a part of light reflects from upper side 104 after the first cambered surface 101 and the second cambered surface 102 reflections again in addition, after the refraction and total reflection of lens, the direction of propagation of light is precisely controlled.The light shooting out from the upper side 104 of lens carries out secondary mixed light again, has realized different-colour light and has evenly mixed to obtain the object of uniform light spots.
Shell 40 adopts heat sink material to make, and its lateral surface is provided with some radiator structures, and the heat distributing when LED light source and power work is delivered to shell 40, then is dispersed into external environment by radiator structure.
Fig. 5 is the near field hot spot uniformity figure of an embodiment of the utility model lens, and the uniformity within the scope of circle, up to 88%, with reference to the curve of figure 6, can find out that curve is very level and smooth, and veiling glare is less, and hot spot is even.Illustrate by this lens arrangement, can make smooth colour mixture of all kinds even, form uniform hot spot.
More than that better enforcement of the present utility model is illustrated, but the utility model is created and is not limited to described embodiment, those of ordinary skill in the art also can make all equivalent variations or replacement under the prerequisite without prejudice to the utility model spirit, and the distortion that these are equal to or replacement are all included in the application's claim limited range.
