Abstract
The utility model discloses a novel rectangular light spot LED lens which comprises a lens body. The top of the lens body is provided with an emitting surface which is composed of a plurality of emitting strip arrays. Each emitting strip is obtained through successively connecting a plurality of outwards projected arc-shaped surface units. Each arc-shaped surface unit has an elongated arc surface structure. According to the novel rectangular light spot LED lens with the structure, a novel design in which a tooth-shaped arc-shaped emitting surface is matched with a total reflection surface is disclosed, and an integrally uniform rectangular light spot without difference between a bright strip and a dark strip or difference between a yellow strip and a blue strip is realized.
Description
Technical field
The utility model relates to light emitting diode (LED, LightEmittingDiode) technical field, is specifically related to a kind of novel rectangular light spot LED lens.
Background technology
Rectangular light spot (or claiming ellipse light spot) LED lens demand in market is large, particularly at wall lamp, and the aspects such as advertising lamp box.The rectangular light spot LED lens that market occurs now adopt bar shaped dentation exit facet collocation total reflection structure to realize rectangular light spot more.But single bar shaped dentation exit facet is planar structure, due to the optical characteristics restriction of itself, hot spot is prone to the light and shade region of bar shaped and the champac region of bar shaped, or the overall hot spot uniformity is inadequate.
Utility model content
The purpose of this utility model has been to disclose a kind of novel rectangular light spot LED lens, has solved hot spot and has been prone to the light and shade region of bar shaped and the champac region of bar shaped, the inadequate problem of the overall hot spot uniformity.
For achieving the above object, the utility model adopts following technical scheme:
Novel rectangular light spot LED lens, comprise lens body, and the top of this lens body is exit facet, and this exit facet is made up of several outgoing strip arrays, and each outgoing bar is is outwards connected and composed outstanding arcwall face unit successively by several.
Further, the described arcwall face unit globoidal structure that is rectangle.
Further, described several outgoing bars are profile of tooth array syndeton.
Further, comprise the groove for placing LED, this groove is positioned at the bottom of described lens body, and groove is made up of first plane of incidence and second plane of incidence, and first plane of incidence forms the bottom of groove, and second plane of incidence forms the sidewall of groove; The sidewall of lens body is fully reflecting surface; First plane of incidence, second plane of incidence, fully reflecting surface and described exit facet cooperatively interact.
Further, described first plane of incidence is outwards outstanding half-cone raised structures, and described second plane of incidence is round trapezium structure.
Further, described fully reflecting surface is the flared structure of evagination.
Compared with prior art, the beneficial effects of the utility model:
The exit facet that the utility model adopts is the composite construction of profile of tooth array in conjunction with arcwall face, discloses a kind of design of brand-new dentation cambered surface exit facet collocation total reflection structure, realize without between light and shade bar, and without between champac bar, hot spot entirety rectangular light spot uniformly.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.

The specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.
A kind of novel rectangular light spot LED lens of embodiment as shown in Figures 1 to 5, comprise lens body, the top of this lens body is exit facet 1, and this exit facet 1 is made up of several outgoing bar 11 arrays, and each outgoing bar 11 is is outwards connected and composed outstanding arcwall face unit 111 successively by several.Arcwall face unit 111 globoidal structure that is rectangle.Several outgoing bars 11 are profile of tooth array syndeton.The radian of arcwall face unit 111 is greater than 30 °.The exit facet that the present embodiment adopts is that profile of tooth array (as shown in Figure 3) is in conjunction with the arcwall face composite construction of (as shown in Figure 5), a kind of design of brand-new dentation cambered surface exit facet collocation total reflection structure is disclosed, realize without between light and shade bar, without between champac bar, hot spot entirety rectangular light spot uniformly.
The present embodiment comprises the groove 2 for placing LED, and groove 2 is positioned at the bottom of lens body, and groove 2 is made up of first plane of incidence 21 and second plane of incidence 22, and first plane of incidence 21 forms the bottom of groove, and second plane of incidence 22 forms the sidewall of groove.The sidewall of lens body is that fully reflecting surface 3, the first planes of incidence 21, second plane of incidence 22, fully reflecting surface 3 and exit facet 1 cooperatively interact.
First plane of incidence 21 is outwards outstanding half-cone raised structures, and second plane of incidence 22 is round trapezium structure.Fully reflecting surface 3 is the flared structure of evagination.
Other structure of a kind of novel rectangular light spot LED lens of the present embodiment is referring to prior art.
The utility model is not limited to above-mentioned embodiment, if various changes of the present utility model or modification are not departed to spirit and scope of the present utility model, if within these changes and modification belong to claim of the present utility model and equivalent technologies scope, the utility model is also intended to comprise these changes and modification.
