Abstract
The utility model relates to a novel lens for an LED (light emitting diode) lamp. The lens is in a special-shaped structure which consists of a cylindrical structural body and a conical frustum shaped structural body; the big bottom face of the conical frustum shaped structural body is connected with the end face of the cylindrical structural body, and the diameter of the big bottom face of the conical frustum shaped structural body is equal to that of the end face of the cylindrical structural body; the outer end face of the cylindrical structural body forms the upper end face of the lens, and the small bottom face of the conical frustum shaped structural body forms the lower end face of the lens; the lower end face of the lens is provided with a blind hole, the diameter of an orifice of the blind hole is larger than that of the bottom of the blind hole, and the orifice and the bottom of the blind hole are in smooth transition through a conical surface; the bottom of the blind hole is spherical convexly; the upper end face of the lens is provided with a plurality of grooves which are axially parallel; the plurality of grooves are arranged at equal intervals, and each two adjacent grooves are in smooth transition through a convex camber surface; the cross section of each groove is a concave arc. The novel lens for the LED lamp has the advantages that the novel lens enables light emitted by the LED lamp to be more uniform, and no evident bright spot exits.
Description
Technical field
The utility model relates to a kind of LED lamp, relates in particular to a kind of New LED lamp lens.
Background technology
In some application scenario, need the irradiation area of LED lamp without speck, therefore need to improve the lens of LED lamp, make it that light is projected to field of illumination equably.
Utility model content
For the problem in background technology, the utility model proposes a kind of New LED lamp lens, its structure is: described lens-shape is polymorphic structure; Described polymorphic structure is combined by a cylindrical structural body and a truncated cone-shaped structure; The large bottom surface of described truncated cone-shaped structure is connected with the end face of cylindrical structural body, and the large bottom surface diameter of truncated cone-shaped structure is identical with the diameter of cylindrical structural body; The outer face of cylindrical structural body forms the upper surface of lens, and the handle face of truncated cone-shaped structure forms the lower surface of lens; On the lower surface of described lens, be provided with blind hole, the orifice diameter of described blind hole is greater than diameter at the bottom of hole, seamlessly transits between at the bottom of aperture and hole by taper seat; It at the bottom of the hole of blind hole, is the sphere of evagination; On the upper surface of described lens, be provided with many grooves, many grooves axially parallel to each other; Many groove spaced sets, the cambered surface by evagination between adjacent two grooves seamlessly transits; The cross section of groove is the circular arc of indent.
Principle of the present utility model is: during use, the illuminating part of LED is placed in the groove on lens, light is injected lens in groove, light loss is less, after the refraction of lens, especially after many groove refractions of lens upper surface, light can be incident upon irradiation area equably, can not form obvious speck.
For the ease of installing, inventor has also been aforementioned Lens Design special mounting bracket, on mounting bracket, be provided with the mounting groove and the corresponding limiting stand terrace that mate with lens shape, correspondingly, inventor has also done following processing to lens: the junction of cylindrical structural body and truncated cone-shaped structure is provided with the spacing ring of evagination.Spacing ring mates with the limiting stand terrace on mounting bracket, for the position to lens, positions.The top of mounting bracket upper limit step surface is also provided with a plurality of clamping projections, in clamping projection and limiting stand terrace are clamped in spacing ring.
For fear of lens, in mounting bracket, arbitrarily rotate, the utility model has also been done following improvement: the structure surface of spacing ring below is provided with square projection.Corresponding position on mounting bracket is provided with the stopper slot mating with square projection, and when lens insert after mounting bracket, square projection is just stuck in stopper slot, thereby lens cannot arbitrarily be rotated.
Useful technique effect of the present utility model is: the light that LED lamp is sent is comparatively even, without obvious speck.
