Abstract
The utility model relates to the technical field of optical lenses, particularly to a novel lens for a high-power LED street lamp. The novel lens has a body surrounded by a compound curved surface and an upper surface, and the edge of the upper surface protrudes out of the compound curved surface and axially extends to form to a flange for facilitating mounting, wherein a compound slot is formed from the upper surface to the interior of the body and comprises a V-shaped slot positioned at the middle part thereof and conical slots positioned at the two ends thereof, and round corners are formed at the bottom of the compound slot. By adopting the above structure, the distribution of illumination light is more uniform and the illumination effect is better. The novel lens enriches the varieties of optical lenses, meets the requirement for using in special cases, and is helpful for the generalization and the usage of high-power LED lamps.
Description
Technical field:
The utility model relates to the optical lens technical field, refers in particular to a kind of new type lens of high-power LED street lamp special use.
Background technology:
Because that the LED light fixture has is low in energy consumption, luminance is high, long service life and superior energy-conserving and environment-protective characteristic, has obtained application more and more widely.At present, high-powered LED lamp also is applied at aspects such as street lamp, Tunnel Lamp, shot-light and extraordinary lamps.Requisite parts during optical lens is used as high-powered LED lamp, it has different designs according to factors such as the purposes of LED lamp and use occasions.And the kind of existing optical lens and performance etc. obviously can't satisfy the requirement of more and more occasions and more and more higher use standard, and this has just hindered the promotion and application of high-powered LED lamp, therefore still need research staff's the various lens of design energetically.
The utility model content:
The purpose of this utility model is to provide a kind of novel used lens of high-powered LED lamp, enriches the lens kind, satisfies more occasion needs.
The utility model realizes that the technical scheme that its purpose adopts is: the new type lens of high-power LED street lamp special use, it has by plane on a compound curved surface and and encloses the entity that forms, the described horizontal edge of going up protrudes in described compound curved surface and extends axially the flange that formation is convenient to install, wherein: offer a compound groove to entity inside by the described plane of going up, and this compound groove comprises " V-arrangement " groove that is positioned at the middle part and the conical surface type groove that is positioned at two ends, and compound trench bottom forms fillet.
The utility model can make illuminating ray be more evenly distributed after adopting said structure, and illuminating effect is better, enriches the kind of optical lens, satisfies the use needs of special occasions, helps promoting the use of of high-powered LED lamp.
Description of drawings:
Fig. 1 is a stereogram of the present utility model;
Fig. 2 is a front view of the present utility model;
Fig. 3, Fig. 4 are respectively the profiles of A-A among Fig. 2, B-B.
The specific embodiment:
Below in conjunction with specific embodiments and the drawings the utility model is further specified.
Shown in Fig. 1～4, the new type lens of high-power LED street lamp special use described in the utility model, have by plane 2 on a compound curved surface 1 and and enclose the entity that forms, described 2 edges, plane of going up protrude in described compound curved surface 1 and extend axially formation flange 21, and the effect of this flange 21 is installations of being convenient to lens.
Furthermore, the described plane 2 of going up offers a compound groove 3 to entity inside, and this compound groove 3 comprises " V-arrangement " groove 31 that is positioned at the middle part and the conical surface type groove 32 that is positioned at two ends, and compound groove 3 bottoms formation fillet.Described compound groove 3 can be regarded as to be stretched by the elder generation of the similar delta-shaped region shown in B-B profile straight line and forms V-shaped groove 31, winds the axis rotation half cycle perpendicular to last plane 2 then, thereby at one end forms conical surface type groove 32, and the other end is pressed the same manner formation.
Certainly more than is a specific embodiment of the present utility model; also Change Example such as cross sectional shape are semicircle or half elliptic etc. to the shape of its compound groove as required; its structural principle and effect are close with the utility model, therefore also should be within protection domain of the present utility model.
In sum, the utility model is simple in structure, helps applying of high-powered LED lamp, especially as the application of aspects such as street lamp or searchlight.
