Abstract
The utility model provides a bi -concave backlight lens of improvement, including the lenticular body, the lenticular body is round platform shape, lenticular body one end is provided with shrinkage pool in the reflection of light, and the other end is provided with the LED install the chip hole, the side of lenticular body includes and is close to the round platform side of shrinkage pool in the reflection of light, and be close to the arc side in LED install the chip hole. When the LED chip gives off light, at first disperse the distribution through the concave surface in LED install the chip hole with beam refraction, the concave surface of shrinkage pool evenly reflects light the side of lens and reflects the lenticular body in the rethread reflection of light, the side makes luminous angle can reach 180 by constituteing in round platform side and arc side.
Description
Technical field
The utility model relates to LED light source, particularly relates to backlight lens.
Background technology
LED illumination is a kind of emerging lighting energy because its long service life, efficiency high, consume energy low and be widely used.Also often LED chip luminous lighting is adopted in the backlight at present, backlight comprises luminous LED chip and backlight lens, these backlight lens and LED chip encapsulate and combine, soft LED illumination effect can be played, improve LED refract light rate, guide the luminous direction of illumination of LED etc. effect.
The common backlight lens of tradition comprise dome-shaped top surface and bottom surface, and bottom surface concaves the light source mounting hole that traps out, and LED chip is arranged in light source mounting hole, and the rays pass through lens body sent is shot out, and throws light on.LED lamp bead is arranged in light source mounting hole, emits beam from end face through lens, and the field of illumination that the freedom of end face carries out irradiating comprehensively is limited, and maximum illumination angle is no more than the angular range of 160 °.And the distance of Uniform Illumination is limited, and the top thickness of the free form surface of backlight lens is comparatively large, makes the integral thickness of product uncontrollable in more rational scope.
Summary of the invention
The technical problems to be solved in the utility model is according to above-mentioned the deficiencies in the prior art, provides that a kind of irradiation angle range is wide, the distance of Uniform Illumination is large and the backlight lens that the thickness of backlight lens is less.
The technical solution of the utility model is as follows:
A kind of bi-concave backlight lens of improvement, include lenticular body, described lenticular body is truncated cone-shaped, described lenticular body one end is provided with reflective inward recess, the other end is provided with LED chip installing hole, the side of described lenticular body comprises the frustum cone side near described reflective inward recess, and the arcuate flanks of close described LED chip installing hole.
Further, described reflective inward recess is conical bore, and described LED chip installing hole is round platform hole, and the bottom surface in described round platform hole conically.
Further, described side is provided with spark lines.
Further, described LED chip installing hole arranged outside has sawtooth reflexed light ring.
Further, described lenticular body is provided with installation suspension column.
Compared with prior art, the utility model embodiment has following beneficial effect: when LED chip is luminous, first by the concave surface of LED chip installing hole, light refraction is dispersed distribution, then by the concave surface of reflective inward recess uniform light reflexed to the side of lens and reflect lenticular body; Described side is made up of frustum cone side and arcuate flanks, makes lighting angle can reach 180 °; Side is provided with spark lines, and lower surface is provided with sawtooth reflexed light ring, and hot spot is uniformly distributed.

Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figures 1 and 2, a kind of bi-concave backlight lens of improvement, include lenticular body 10, described lenticular body 10 is in truncated cone-shaped, described lenticular body 10 one end is provided with reflective inward recess 30, the other end is provided with LED chip installing hole 40, and the side 20 of described lenticular body 10 comprises the frustum cone side 21 near described reflective inward recess 30, and the arcuate flanks 22 of close described LED chip installing hole 10.
Described reflective inward recess 30 is conical bore, and described LED chip installing hole 40 is round platform hole, and the bottom surface in described round platform hole conically.
Described side 20 is provided with spark lines (unmarked in figure).
Described LED chip installing hole 40 arranged outside has sawtooth reflexed light ring 50.
Described lenticular body 10 is provided with installs suspension column 60.
The utility model embodiment can realize large-area Uniform Illumination under a lot of distance conditions, the area of field of illumination is improve relative to traditional Random Curved Surface Designing, main is the distance of Uniform Illumination breaking through traditional design, the distance of uniform irradiation can be made 10mm by this, the thickness of down straight aphototropism mode set can be reduced to greatest extent, the thickness of product is reduced, and this product a lot of workinprocess cost less of traditional product can be controlled effectively simultaneously.
When actual installation, by installing suspension column 60, make the center of lenticular body 10 and light source center on the same axis.When LED chip is luminous, first by the concave surface of LED chip installing hole 40, light refraction is dispersed distribution, then by the concave surface of reflective inward recess 30 uniform light reflexed to the side 20 of lens and reflect lenticular body 10; Described side 20 is made up of frustum cone side 21 and arcuate flanks 22, and lighting angle can be reached; Side 20 is provided with spark lines, and lower surface is provided with sawtooth reflexed light ring 50, and hot spot is uniformly distributed.This design to traditional free form surface structure, achieve huge breakthrough in uniform irradiation distance, the thickness of straight-down negative TV can be realized to accomplish in the thickness range of lenticular body 10 of side entering type TV, and cost can effectively reduce most.
Above disclosedly be only the utility model preferred embodiment, certainly can not limit the interest field of the utility model with this, therefore according to the equivalent variations that the utility model claim is done, still belong to the scope that the utility model is contained.
