Abstract

The utility model relates to an LED (Light Emitting Diode) polarizing lens capable of replacing a metal halide lamp, belonging to the field of LED light source lighting. The LED polarizing lens comprises a lens body, wherein the lens body is a stage body, one end of the stage body serves as a top face, the other end of the stage body serves as a bottom face, the center of the top face is provided with a cup-shaped hole, the bottom wall of the hole serves as an exit face of the lens body, the center of the bottom face is provided with a cylindrical assembling hole, and the bottom wall of the assembling hole serves as an entrance face of the lens body. The LED polarizing lens can form circular and uniform light spots, is good in light efficacy, is environment-friendly and is convenient to dismount and mount.

Description

A kind of LED spreadlight lens

Technical field

The utility model belongs to the lens of LED light source lighting field, espespecially a kind of LED collector lens of desirable cash equivalent halogen lamp.

Background technology

Illuminating lamp at the sight spot, park, the exhibition of interior decoration, guild hall all has indispensable effect.Played the effect of playing up atmosphere, decorating view, beautify the environment.For meeting lighting demand, people still adopt traditional illumination lamp.One of its topmost shortcoming is that power consumption is high.As incandescent lamp, it is interior energy that its principle is based on electric energy conversion, and next luminous by heating, its electric energy almost completely is converted into heat, causes luminance shortage, and the life-span is short, and it also fails to reach the requirement of current low-carbon environment-friendly far away.Metal halogen lamp is AC power work for another example, produces the luminous discharge lamp of arc discharge in the halide mixed vapour of mercury and rare metal, and metal halide lamp is to add the third generation light source that various metal halides are made on the high-pressure sodium lamp basis.Illumination adopts scandium sodium type metal halide lamp, this light fixture has the characteristics such as luminous efficiency is high, color developing is good, be a kind of energy-conservation new light sources that approaches color of sunshine, be widely used in the room lighting in the places such as stadiums, exhibition center, megastore, industrial premises, square, street, station, harbour.

But, in the filler in Metal halogen lamp, mercury being arranged, mercury is noxious material, when lamp processed is annotated mercury, process accidentally, can cause production environment is polluted, diminish the healthy of workman, during the electric arc tube exhaust, there is micro-mercury vapour to discharge, if deal with improperly, can directly enter atmosphere, when the lamp breakage of using, all can be to environment.Metal halide lamp is because brightness is high, volume is little, therefore comparative lifetime is short.

The utility model content

In order to overcome the problems referred to above, this is novel provides a kind of LED spreadlight lens, can the conglobate uniform light spots of shape, and light transmittance efficiency is good, and environmental protection is for convenience detach and install.

In order to achieve the above object, be achieved through the following technical solutions:

A kind of LED spreadlight lens, comprise lens body, described lens body is stage body, one end of described stage body is end face, the other end is bottom surface, and the hole of a cup-shaped, the exit facet that the diapire of described hole is lens body are offered in described end face center, a cylindrical pilot hole, the plane of incidence that the diapire of described pilot hole is lens body are offered in the center of described bottom surface.

The edge of described end face arranges the small stair of a circle.The described plane of incidence is relative with described exit facet, and be arranged in parallel.Make latticed finish coat on described exit facet.Described latticed finish coat is cellular finish coat.Its outside of lens body makes latticed finish coat.Described latticed finish coat is arranged in a combination by rectangular preiection.

The beneficial effects of the utility model are: the beneficial effects of the utility model are: (1) arranges convex lens and carries out printing opacity one time, adopts the lens of 38 degree to concentrate by bright dipping, obtains the light of homogeneous and bright.(2) side of circular cone stage body can collect the incident sidelight reflect away, and makes light obtain the most perfect utilization, and the circular projected spot effect that obtains concentrating.(3) plane of incidence is designed to the pearl face, and the lateral layout of circular cone stage body is that wire side can make light soft, forms more various hot spot effect.(4) due to the LED environmental protection, save the energy, the characteristics that the life-span is high, can make up the shortcoming of Metal halogen lamp, desirable cash equivalent halogen lamp.

The accompanying drawing explanation

Fig. 1 is this novel profile;

The enlarged drawing that Fig. 2 is this novel plane of incidence;

Fig. 3 is this novel unitary side view.

In figure 1, lens body; 2, end face; 3, bottom surface; 4, the plane of incidence; 5, exit facet; 6, hole; 7, pilot hole; 8, small stair.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is further described:

As shown in Figure 1, a kind of LED spreadlight lens, comprise lens body 1, described lens body 1 is stage body, and an end of described stage body is end face 2, the other end is bottom surface 3, the hole 6 of a cup-shaped is offered at described end face 2 centers, the exit facet 5 that the diapire of described hole 6 is lens body 1, and a cylindrical pilot hole 7 is offered at the center of described bottom surface 3, in order to light emitting diode to be set, the plane of incidence 4 that the diapire of described pilot hole 7 is lens body 1.The plane of incidence 4 can be that 38 degree are adjusted and adapted to when designing the size of the plane of incidence 4 according to characteristic or the crevice projection angle of LED light source.

The edge of described end face 2 arranges the small stair 8 of a circle, so that lens body 1 is equipped with lamp.The described plane of incidence 4 is relative with described exit facet 5, and be arranged in parallel.As shown in Figure 2, make latticed finish coat on described exit facet 5.Described latticed finish coat is cellular finish coat.Lens body 1 its outside makes latticed finish coat.As shown in Figure 3, described latticed finish coat is arranged in a combination by rectangular preiection.Lens body 1 use transparent material is made, as plastic cement PMMA, PC etc.

The LED lamp is arranged on pilot hole 7, light enters the plane of incidence 4, adopt the convex lens of 38 degree, form bright circular light spot, cellular finish coat through exit facet 5 makes emergent ray softer again, the honeycomb finish coat of the arranged outside of lens body 1 has the effect of collection to sidelight simultaneously, has improved the utilization rate of light source.

The above not imposes any restrictions this novel technical scope, and all any modification, equivalent variations and modifications of above embodiment being done according to the utility model technical spirit all still belong in the scope of this novel technical scheme.
