Abstract

A spreadlight lens of an LED (Light-Emitting Diode) lamp relates to a lens for an LED lamp and comprises a lens body, wherein the lens body is a cone frustum, a cylindrical hole is arranged at the center of a large bottom end of the lens body, and the bottom wall of the hole is used as an emergent surface of the lens body; an assembling hole provided with an LED is arranged at the center of a small bottom end of the lens body, the bottom wall of the assembling hole is used as an incident surface of the lens body, A-grid decorative layer is curved on the emergent surface, and a B-grid decorative layer is curved on the end surface of the large bottom of the lens body. The spreadlight lens has the beneficial effects that light spots projects in a ring shape, the projection angle of light is 25 degrees, and intensive projection of light is achieved; light projection is even, change of light colors can be realized by changing LED lamp wicks emitting light of different colors; and the LED is adopted as a light source. Therefore, the spreadlight lens has low energy consumption, small size, long service life and low maintenance cost.

Description

A kind of LED lamp spreadlight lens

Technical field

The utility model relates to the lens that are used for the LED lamp, refers to a kind of LED lamp spreadlight lens especially.

Background technology

Outside the building views such as profile, square, park, sub-district and various tourist attractions throw light on usually at present.Beautify the environment to reach, in the Landscape Lighting of rendered atmosphere and effect; What generally use is conventional lamp, and like incandescent lamp, fluorescent lamp, high-pressure sodium lamp, metal halide lamp, high-pressure mercury lamp and low-pressure sodium lamp etc., the major defect of this type light fixture is to use the life-span short; Light efficiency is low; Energy consumption is high, and photochromic control is difficult, and volume is big and maintenance cost is high.Also there is a certain distance in this with the requirement that country advocates energy-saving and emission-reduction.

Summary of the invention

The utility model is intended to overcome the above-mentioned deficiency of prior art, and meeting the market requirement provides a kind of LED lamp spreadlight lens.Its characteristics: the rounded projection of projection shape of

hot spot, light is concentrated projection;

illumination projection evenly, photochromic can conversion;

light source adopts the LED luminous tube, and energy consumption is low, volume is little, long service life and maintenance cost are low.

For this reason, a kind of LED lamp of the utility model spreadlight lens adopts following technical scheme:

A kind of LED lamp of structure the utility model spreadlight lens comprises lens body, and said lens body is circular cone shape, and system one columned hole is opened in the center of the big bottom of its lens body, and the diapire of this hole is the exit facet of lens body; Open the pilot hole that system is provided with light emitting diode in the center of the little bottom of lens body; The diapire of this pilot hole is the plane of incidence of lens body; The exit facet and the plane of incidence are relative; Make the latticed finish coat of A on the said exit facet; On the end face at the big end of lens body, make the latticed finish coat of B, the latticed finish coat of A is combined by numerous circular protrusions on said exit facet or regular polygon bump array, and the latticed finish coat of B is combined by numerous circular protrusions or the regular polygon bump array on the end face at the big end of lens body.

Technique scheme is further set forth:

Be shaped on the installing and locating button on the lens body, so that lens body and lamp body are equipped.

The shape of the plane of incidence 4 designs according to the crevice projection angle that optical characteristics and this projection source of light emitting diode requires to reach.

Lens body is made with transparent material, like plastic cement PMMA etc.

The beneficial effect of the utility model is: one of which, and the rounded projection of projection shape of hot spot, ray cast is scattered and is angle 25 degree, and light is concentrated projection; Its two, illumination projection evenly photochromicly can realize conversion through the LED wick (being light emitting diode) of more changing different colours; Its three, light source adopts light emitting diode, energy consumption is low, volume is little, long service life and maintenance cost are low.

Among the figure: 1, lens body; 2, installing and locating button; 3, pilot hole; 4, the plane of incidence; 5, exit facet; 6, the latticed finish coat of A; 7, the latticed finish coat of B.

The specific embodiment

Below, introduce the specific embodiment of the utility model in conjunction with accompanying drawing.

Extremely shown in Figure 3 like Fig. 1; A kind of LED lamp of the utility model spreadlight lens comprises lens body 1, and said lens body 1 is circular cone shape; System one columned hole is opened in the center of the big bottom of its lens body 1, and the diapire of this hole is the exit facet 5 of lens body 1; Open the pilot hole 3 that system is provided with light emitting diode in the center of the little bottom of lens body 1; The diapire of this pilot hole 3 is these planes of incidence 4 of 1 of lens; Exit facet 5 is relative with the plane of incidence 4; Make the latticed finish coat 6 of A on the said exit facet 5; On the end face at the big end of lens body 1, make the latticed finish coat 7 of B, the latticed finish coat 6 of A is combined by the numerous circular protrusions on said exit facet 5 or the bump array of regular polygon, and the latticed finish coat 7 of B is combined by numerous circular protrusions or the regular polygon bump array on the end face at the big end of lens body 1.

Be shaped on installing and locating button 2 on the lens body 1, so that lens body 1 is equipped with lamp body.

The shape of the plane of incidence 4 designs the shape approximation spherical of this plane of incidence 4 according to the crevice projection angle that optical characteristics and this light source of light emitting diode requires to reach.

Lens body is made with transparent material, like plastic cement PMMA etc.

The above only is the preferred embodiment of the utility model, is not that the technical scope of the utility model is done any restriction.The technical staff of the industry; Under the inspiration of present technique scheme; Can make some distortion and revise, every technical spirit according to the utility model all still belongs in the scope of the utility model technical scheme above any modification, equivalent variations and modification that embodiment did.
