Description

LED wall wash lamp lens

Technical field

Lens are the utility model is related to, more particularly, to LED wall wash lamp lens.

Background technology

LED wall wash lamp lens mainly have normal incidence face, the side plane of incidence, reflecting surface and exit facet, wherein exit facet energy at present Enough it is emitted the light of normal incidence face injection and after the refraction of the side plane of incidence by the light of reflective surface, and exit facet is post Face.In the prior art, the angle of LED wall wash lamp lens is controlled to be controlled mainly by reflecting surface and exit facet, reflecting surface makes light Line collimates, and the cylinder of exit facet expands the beam angle in a direction, and it is difficult to make light by reflecting surface and exit facet into ellipse to make hot spot More light is more radiated at metope to line, and illumination is relatively low at metope in light fixture, especially less than lens height Metope almost without light irradiate, cause metope Illumination Distribution not uniform enough, as shown in Figure 1.In summary problem, it is existing to wash Problems be present in pinup lens：

1. it is few that lens exit facet is assigned to metope light, cause the metope efficiency of light energy utilization low.

2. it is few that lens exit facet is assigned to strong face bottom light, cause metope uneven illumination even.

Utility model content

Technical problem to be solved in the utility model is：A kind of LED wall wash lamp lens are provided, by part emergent ray point Metope nearby is fitted on, improves metope uniformity of illuminance.

Technical scheme is used by the utility model solves its technical problem：LED wall wash lamp lens, including incidence hole, Catoptric arrangement and refraction structure, catoptric arrangement and refraction structure are oppositely arranged；Catoptric arrangement includes first plane of incidence, fully reflecting surface And first exit facet, first plane of incidence include normal incidence face and the side plane of incidence, the side plane of incidence is towards fully reflecting surface；Refraction structure Including second plane of incidence and the second exit facet, the second exit facet is towards metope.

Further, second plane of incidence and the second exit facet are curved surface.

Further, the fully reflecting surface is combined by multiple scales.

Further, the curvature between adjacent scale face is discontinuous.

Specifically, the incidence hole is made up of the first incidence hole and the second incidence hole, light is entered anti-by the first incidence hole Structure is penetrated, light enters refraction structure by the second incidence hole.

Further, the depth of first incidence hole is more than the depth of second incidence hole.

Further, the sectional area of second incidence hole is more than the sectional area of first incidence hole.

The beneficial effects of the utility model are：LED lens are arranged to catoptric arrangement and refraction structure two by the utility model Part, catoptric arrangement can will be irradiated to distant place metope after light collection, light can be irradiated to nearby metope by refraction structure, Especially less than lens height metope, make so to be achieved that the metope close to wall lamp is illuminated, so as to metope illumination more Uniformly；The plane of incidence of refraction structure and exit facet are curved surface simultaneously, by changing the face type of curved surface more light can be made inclined To metope, so as to add the efficiency of light energy utilization of metope.

Wherein, 1 is catoptric arrangement, and 2 be refraction structure, and 11 be the side plane of incidence of catoptric arrangement, and 12 be the complete of catoptric arrangement Reflecting surface, 13 be the exit facet of catoptric arrangement, and 14 be the normal incidence face of catoptric arrangement, and 21 be the plane of incidence of refraction structure, and 22 are The exit facet of refraction structure, S are light source.

Embodiment

Below in conjunction with the accompanying drawings and embodiment further illustrates to the utility model.

As shown in Fig. 2 embodiment provides a kind of LED wall wash lamp lens, including incidence hole, catoptric arrangement 1 and refraction structure 2；Catoptric arrangement 1 and refraction structure 2 are oppositely arranged, and catoptric arrangement 1 is used to that the metope of distant place, folding will to be irradiated to after incident light rays Structure 2 is penetrated to be used to that metope nearby will to be irradiated to after refracting light incident.

Above-mentioned catoptric arrangement 1 includes first plane of incidence, the exit facet 13 of fully reflecting surface 12 and first, the first incident bread Normal incidence face 14 and the side plane of incidence 11 are included, the fully reflecting surface 12 is combined by multiple scales, and between adjacent scale face Curvature it is discontinuous.

Above-mentioned refraction structure 2 includes second plane of incidence 21 and the second exit facet 22, and the second exit facet 22 is towards wall nearby Face, the metope nearby include the metope less than lens height, and second plane of incidence 21 and the second exit facet 22 are free form surface, can With the curved surface face type by changing second plane of incidence 21 and the second exit facet 22, more light are made to be biased to metope, so as to add The efficiency of light energy utilization of metope.

Above-mentioned incidence hole is made up of the first incidence hole and the second incidence hole, and the first incidence hole is located at the lower end of catoptric arrangement 1, Light enters catoptric arrangement 1 by the first incidence hole, and the second incidence hole is located at the lower end of refraction structure 2, and light is by the second incidence hole Into refraction structure 2.In embodiment, the depth of first incidence hole can be set greater than to the depth of second incidence hole Degree, the depth of the first incidence hole is deeper, then the side plane of incidence 11 of catoptric arrangement can incident more perspective light, so as to reflect The fully reflecting surface 12 of structure can reflect more light to the metope of distant place；The sectional area of second incidence hole can also be set The sectional area more than first incidence hole is set to, the sectional area of the second incidence hole is bigger, then the plane of incidence 21 of refraction structure can With the light of incident more perspective, more light can be reflected to metope nearby so as to the exit facet 22 of refraction structure.

As shown in figure 3, the light path principle of embodiment is as follows：

Light source S emit beam be divided into three parts Jin Ru not the side plane of incidence 11 of catoptric arrangement, the normal incidence face of catoptric arrangement 14th, the plane of incidence 21 of refraction structure；Light is after the side plane of incidence 11 of catoptric arrangement reflects by the fully reflecting surface of catoptric arrangement 12 total reflections, are then emitted from the exit facet 13 of catoptric arrangement；Light entered catoptric arrangement normal incidence face 14 reflect after, from anti- The exit facet 13 for penetrating structure is emitted, and the light that the exit facet 13 of catoptric arrangement is emitted is irradiated to distant place metope；Light is through superrefraction After the plane of incidence 21 of structure reflects, then it is refracted the exit facet 22 of structure and reflect away, the outgoing of exit facet 22 of refraction structure Light is irradiated to nearby metope, is so achieved that the metope close to wall lamp is illuminated, especially less than lens height metope Also it is illuminated, so as to which metope illumination is more uniform.

Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model All any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model Protection domain within.
