Abstract

The utility model discloses a light barrier added lens which comprises a lens bottom, a lens top, a lens side wall and a light barrier, wherein the lens top is an emergent surface, the lens side wall is a reflecting surface, and the lens bottom is an incident surface; the lens bottom adopts a groove structure used for mounting an LED (light emitting diode); the groove structure comprises an inner groove and an outer groove surrounding the inner groove; and the inner groove and the outer groove are separated by the light barrier. With the adoption of the structure, residual light can be collected as far as possible, and a plurality of bright areas are prevented from being generated on the periphery of a main light spot.

Description

Add light barrier lens

Technical field

The utility model relates to light emitting diode (LED, Light Emitting Diode) technical field, is specifically related to add light barrier lens.

Background technology

In order to improve the power of LED light fixture and to reduce costs, the light fixture that occurs at present plurality of LEDs combined light source, lens for this combined light source, conventionally lens inside is placed with plurality of LEDs, this just causes light after lens, the a large amount of remaining light of the peripheral generation of main spot, cannot utilize this part remaining light mobile phone.And also may cause main spot periphery to occur several clear zones.

Utility model content

The purpose of this utility model is to disclose and adds light barrier lens, has solved the existing lens that are placed with plurality of LEDs, and main spot is peripheral produces a large amount of remaining lights, and occurs the problem in several clear zones.

For achieving the above object, the utility model adopts following technical scheme:

Add light barrier lens, comprise lens bottom, lens top, lens sidewall and light barrier, lens top is exit facet, and lens sidewall is reflecting surface, and lens bottom is the plane of incidence; Described lens bottom is the groove structure for diode installed LED, and this groove structure consists of inner groovy and the outer groove that is surrounded on this inner groovy, and inner groovy and outer groove separate by described light barrier.

Further, the frosted light barrier of light barrier for processing through frosting technology.

Further, the rounded structure of described inner groovy, described outer groove is cirque structure, inner groovy and outer groove coaxial cooperation.

Further, the bottom surface of described outer groove consists of several cambered surface unit annular arrays, and described cambered surface unit is the globoidal structure of protrusion.

Further, described LED is installed on the position of the bottom surface of corresponding described cambered surface unit and described inner groovy.

Further, described lens top is planar structure.

Further, described lens sidewall is round trapezium structure, and the camber line evagination of lens sidewall.

Further, described in, adding light barrier lens is the overall structure that transparent material is made.

Compared with prior art, the beneficial effects of the utility model:

1, the utility model adopts the design of light barrier, and on light barrier surface, does frosted and process, and can collect remaining light as far as possible, and prevents the some clear zones of the peripheral generation of main spot;

2, the design of the employing separated inner groovy of light barrier and outer groove, and outer groove consists of the cambered surface cell array of giving prominence to, and has both reached the effect of optically focused, can further prevent again the some clear zones of the peripheral generation of main spot.

The specific embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.

Embodiment adds light barrier lens as shown in Figures 1 to 5, comprises lens bottom 1, lens top 2, lens sidewall 3 and light barrier 4, and lens top 2 is exit facet, and lens sidewall 3 is reflecting surface, and lens bottom 1 is the plane of incidence; Lens bottom 1 is for the groove structure of LED5 is installed, and this groove structure consists of inner groovy 11 and the outer groove 12 that is surrounded on this inner groovy 11, and inner groovy 11 and outer groove 12 separate by light barrier 4.In the present embodiment, the bottom surface 121 of the bottom surface 111 of inner groovy, outer groove and the side of outer groove 123 form the plane of incidence.

The frosted light barrier of light barrier 4 for processing through frosting technology.

Along the cross section B-B direction that adds light barrier lens, the rounded structure of inner groovy 11, outer groove 12 is cirque structure, and light barrier 4 is cirque structure, inner groovy 11 and outer groove 12 coaxial cooperation.The outer wall of light barrier 4 is provided with several and strengthens cylinder 41, strengthens cylinder 41 and extends along the axis direction X-axis of light barrier 4.The bottom surface 111 of inner groovy is planar structure.The bottom surface 121 of outer groove consists of several cambered surface unit 122 annular arrays, and cambered surface unit 122 is the globoidal structure of protrusion.In the present embodiment, 9 cambered surface unit 122 connect successively, and the edge wheel profile of cambered surface unit 122 is sector structure.LED5 is installed on the position of the bottom surface 111 of corresponding each cambered surface unit 111 and inner groovy.The light that LED5 sends is injected by the plane of incidence, and part light penetrates from exit facet after plane of refraction refraction, and part light directly penetrates from exit facet.

Lens top 1 is planar structure.Lens sidewall 3 is round trapezium structure along longitudinal section A-A direction, and the camber line evagination of lens sidewall 3.Adding light barrier lens is the overall structure that transparent material is made.

The present embodiment adds other structure of light barrier lens referring to prior art.
