The specific embodiment
Hereinafter describe specific embodiment of the utility model with reference to graphic in detail by embodiment.
Fig. 1 is a kind of structural representation of realizing the optical module of ultra-thin LED light fixture described in the utility model.
As shown in Figure 1, comprise led light source as a kind of optical module of ultra-thin LED light fixture of realizing of the utility model; And the lens that are configured in led light source array top, lens have the plane of incidence 101, first fully reflecting surface 102, second fully reflecting surface 103 and exit facet 104, the light that led light source sends, a part arrives exit facet 104 via the plane of incidence 101 and second fully reflecting surface 103 that is positioned at the lens top; A part arrives exit facet 104 via first fully reflecting surface 102 near the led light source bottom in addition.
Wherein, the form of the composition of the plane of incidence 101 includes but not limited to convex surface, plane or concave surface, in this programme, adopt the convex surface effect best, the core low-angle light " collimation " that the plane of incidence 101 sends LED is low-angle light, follow the reflection via second fully reflecting surface 103 that is positioned at this optical module top, and then from exit facet 104 outgoing.
Further, in this programme, by the high angle scattered light that LED sends, will be via first fully reflecting surface, the 102 surface reflections near the led light source bottom, from exit facet 104 outgoing.Wherein, exit facet 104 is smooth or matte surface, and is good especially with matte surface in the utility model embodiment.First fully reflecting surface 102 near the led light source bottom is the cambered surface that realizes optical total-reflection, and incidence surface can be plane, arc surface or free form surface.
Further, in this programme, second fully reflecting surface 103 is for satisfying " the rounding conical surface " of optical total-reflection, and exiting surface is the diffusing surface of frosted character.
That is, in the present embodiment, the light that LED sends is divided into two parts, and a part arrives exit facet 104 via the plane of incidence 101 and second fully reflecting surface 103 that is positioned at the lens top; A part arrives exit facet 104 via first fully reflecting surface 102 near the led light source bottom in addition; Because the feature of total reflection, light ray energy is loss not, and therefore the light efficiency of whole optical module is very high.
The optical module light-emitting area that LED is small that the utility model is announced converts bigger even light output surface to, thereby reduces the brightness on surface greatly, reduces the effect of dazzle.Simultaneously, the central circular of lens is not luminous, the annulus uniformly light-emitting of periphery, and the light fixture third dimension of composition is strong, and novel structure is realized ultra-thin light fixture outward appearance easily.As shown in Figures 2 and 3, for a kind of lamp system, the array of the optical module that can be mentioned by the embodiment of the invention is formed.Can realize the effect of low dazzle, be formed by led light source array and corresponding lens arra that wherein lens material can use the material that includes but not limited to PMMA, PC or glass.
Adopt the light fixture of the optical module of the utility model embodiment to look like the spherical crown of projection one by one in appearance, spherical crown surface uniformly light-emitting, core is owing to be the inverted cone fully reflecting surface that adopts the top, so there is not beam projecting, thereby it is luminous to look like one by one " annulus ", gives the illumination effect of a kind of solid of people.In addition, the inverted cone part in this programme can also increase circular metal material or metalloid decoration, to increase the aesthetic measure of light fixture.
The optical module of present embodiment adopts the integral type design, can injection moulding etc. processes be shaped, simplify the optical texture of light fixture.The light-emitting area of LED can be increased, reduce light-emitting area brightness, reduce the dazzle impression; This optical module is disposable to shape, and has the characteristics of high light efficiency simultaneously; Fitting structure novelty by this optical module is formed is rich in third dimension, and luminous component is light and dark, and section strengthens the light fixture aesthetic luminous the time; This optical module can be realized ultra-thin light fixture outward appearance, demonstrates fully the characteristics of LED light fixture.
Above-described embodiment is exemplary, and does not wish that they limit technical method of the present utility model.Though describe the utility model in detail with reference to preferred embodiment; but be understood by those skilled in the art that; can under the situation of the spirit that does not depart from the utility model technical method and category, revise or be equal to and replace technical method of the present utility model, these modifications and be equal to the protection category that replacement also belongs to the utility model claims.
