The specific embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
The utility model embodiment provides a kind of secondary lens, the structure of this secondary lens as depicted in figs. 1 and 2, Fig. 1 is the structural representation of the secondary lens of the utility model embodiment, Fig. 2 is four of this secondary lens of the corresponding diagram 1 not views of ipsilateral, the surface of lens body 1 is the same with lens commonly known in the art as can be seen by Fig. 1 and Fig. 2 is exiting surface 2, but this exiting surface 2 and be a monoblock sphere curved surface unlike traditional lens exiting surface, exiting surface 2 in the present embodiment is to be formed by the smooth connection of polylith curved surface, the curvature of these curved surfaces is also not all identical, the equal hyperboloid for being made up of negative camber 2b and positive camber 2a of these curved surfaces particularly, the curvature of interior positive camber is corresponding.Because the exiting surface 2 of lens is made up of a plurality of curved surfaces in the present embodiment, so it is slightly different on the curved surface of corresponding Route for pedestrians and the curved-surface structure of corresponding motor road, the curved surface of the corresponding pavement of the secondary lens in present embodiment trackside is provided with groove 4, the degree of depth of described groove is by being deep to shallow top curve surface transition to described lens body (in order to make the clearer groove 4 that identifies on the secondary lens of those skilled in the art, as shown in Figure 3, Fig. 3 is a kind of status architecture schematic diagram of the described secondary lens of the utility model embodiment, can know the position of finding out this groove 4 from Fig. 3).Emergent ray can more be radiated on the car lane of opposite side curved surface correspondence like this, thereby guarantees to have sufficient light on the car lane, and does not have strong illumination on the Route for pedestrians, also can not produce dazzle, but can satisfy basic lighting demand.Be provided with the depressed part 3 of corresponding light source in the present embodiment in the bottom of lens body 1, when light source placed depressed part 3, light was just injected lens body 1 from depressed part 3 like this, and negative camber 2b and the positive camber 2a through lens body 1 penetrates lens body 1 again.In the present embodiment in order effectively to distribute emergent light, as shown in Figure 2, at depressed part 3 near an end opening spacing of grooves 4 aperture pitch greater than the described depressed part other end.The light that penetrates through hyperboloid has shooting angle preferably like this, thereby the light that penetrates has desirable brightness of illumination.The material of the lens body 1 in the present embodiment be can preventing ultraviolet optics PC (Polycarbonate, Chinese: Merlon), armorphous thermoplastic resin as a kind of high comprehensive performance, have excellent electrical insulating property, extensibility, dimensional stability and chemical resistance, higher intensity, hear resistance and cold resistance.
Because the reflectivity too high (general reflectivity is about 12%) that does not match and cause of the high-index material of lens and air or encapsulating material, cause bigger light loss, so loss of reflecting for effective minimizing light in the present embodiment, on described positive camber 2a and/or negative camber 2b, be coated with anti-reflection film (not shown among Fig. 1-Fig. 3), to increase light extraction efficiency, improve light efficiency, experiment shows generally can improve 6-8%, has improved the output light efficiency of lens so greatly.
The secondary lens of the utility model embodiment in order effectively to utilize the foregoing description to provide also provides a kind of lampshade, and as shown in Figure 4, Fig. 4 is the structural representation of the utility model embodiment lampshade.Can know by Fig. 4 and to find out that the lampshade that present embodiment provides comprises the secondary lens 10 that several above-mentioned utility model embodiment provide, these lens 10 are fixed on the transparent lampshade substrate, each secondary lens 10 can corresponding light source, such as the LED lamp.And, increase the illumination utilization rate on road surface and the vertical and horizontal illumination uniformity on road surface in order to adapt to the width of standard road, and reducing dazzle and light pollution, the lens 10 on the described lampshade of present embodiment divide three rows to arrange with symmetrical manner.Such as when lens are 28, can be with first row and the 3rd each 10 symmetric arrays of row, with 8 of second rows and the 2nd to the 9th corresponding arrangement during first row, the 3rd arranges, can obtain the lampshade that present embodiment shown in Figure 4 provides intrinsic 28 lens like this.The described lampshade of present embodiment adapts to the width of standard road more like this, and three row's light sources effectively increase the illumination utilization rate on road surface and the vertical and horizontal illumination uniformity on road surface, reduce dazzle and light pollution.For effective sealed lamp shade when light fixture is installed, present embodiment is provided with a circle and is used for putting into the seal groove (Fig. 4 is not shown) that sealing ring (such as the sealing ring of materials such as silica gel) seals at the lampshade back side, in order to lampshade is sealed on the lighting, thereby effectively seal each secondary lens 10, prevent that lens from making moist.The described lampshade substrate of present embodiment is the acrylic material, has light transmission preferably.In order to strengthen lampshade appearance and reduction veiling glare, on the lampshade basal plane, also be provided with anti-fog layer (not shown among Fig. 4).The street lamp that the described lampshade of present embodiment has been installed has improved the vertical and horizontal illumination uniformity on road surface, can not produce direct glare, has improved the brightness of illumination of road greatly, reduces even eliminates the light pollution that causes owing to light irradiating angle defective fully.
Based on the lampshade that the foregoing description provides, the utility model embodiment also provides a kind of lighting, and as shown in Figure 5, Fig. 5 is the structural representation of the utility model embodiment lighting.This lighting can comprise the lampshade (being 5 lampshades among Fig. 5) that at least one above-mentioned utility model embodiment provides, each lens in the described lampshade are all corresponding with a light source on the described lighting, by the installing hole on the lampshade 12 lampshade are installed on the light fixture.This light source can be the LED lamp, can certainly be other light sources.And, respirator (not shown among Fig. 5) is installed in lighting for further effectively damp proof, waterproof.
The utility model embodiment not only provides a kind of higher secondary lens of light efficiency of exporting, and the lampshade of these lens and the vertical and horizontal illumination uniformity that light fixture has improved the road surface have been utilized, can not produce direct glare, improved the brightness of illumination of motor road greatly, reduced even eliminate the light pollution that causes owing to light irradiating angle defective fully.
Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; institute is understood that; the above only is a specific embodiment of the utility model; and be not used in and limit protection domain of the present utility model; all within spirit of the present utility model and principle, any modification of being made, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
