The utility model relates to a lens, in particular to a high-power LED lens.

【Background technique】

Due to the remarkable energy-saving effect of LED lights, their applications are becoming more and more widespread, especially for home lighting, shopping malls, etc. , table lamps and stage lighting, etc., especially in terms of lighting, LED lights themselves have not exerted corresponding effects.

In order to solve the problems in the prior art, the utility model makes beneficial improvements.

【Content of utility model】

The purpose of the utility model is to overcome the deficiencies in the prior art and provide a high-power LED lens with simple structure, which can well solve the insufficient brightness concentration, and enable it to emit light rays of different angles and patterns.

In order to solve the above-mentioned technical problems, the utility model adopts the following technical solutions:

The high-power LED lens is characterized in that it includes a conical lens cup body and a mirror surface at the front end. At the end of the lens cup body, there is a small hole for accommodating LED lights. Inside the small hole, there is a non-conductive lens that can refract light from different angles. sphere.

The high-power LED lens is characterized in that the mirror surface is concave.

The high-power LED lens is characterized in that the mirror surface is a convex surface

The high-power LED lens is characterized in that the mirror surface is a plane.

The high-power LED lens is characterized in that a plurality of mutually parallel stripes are densely covered on the mirror surface.

The high-power LED lens is characterized in that the mirror surface is densely covered with a plurality of convex balls.

The high-power LED lens is characterized in that the mirror surface is densely covered with sand grains.

Compared with the prior art, the utility model has the following advantages: since the utility model is specially equipped with a lens for a high-power LED lamp, the shape of the aspheric lens in the small hole of the lens and the light refracted by the LED lamp can be different. In addition, the mirror surface of the lens can be in various shapes, so that the light passing through the lens has various shapes, which meets different needs in different places.

【Detailed ways】

The utility model is described in detail below in conjunction with accompanying drawing:

The high-power LED lens includes a conical lens cup body 1 and a mirror surface 2 at the front end. At the end of the lens cup body 1, there is a small hole 3 for accommodating LED lights. Inside the small hole 3, there are holes that can refract light from different angles. The aspherical surface 4, the surface shape of the aspheric surface 4 satisfies the following equation: $Z={\mathrm{<figure-callout\; id="2"\; label="cy"\; filenames="Y20072006116100061.png,Y20072006116100071.png"\; state="\{\{state\}\}">cy</figure-callout>}}^2/\{1+\sqrt{[1-(1+k){\mathrm{<figure-callout\; id="2"\; label="c"\; filenames="Y20072006116100061.png,Y20072006116100071.png"\; state="\{\{state\}\}">c</figure-callout>}}^2{\mathrm{the\; y}}^2]}\}+{\mathrm{\&alpha;}}_1{\mathrm{the\; <figure-callout\; id="2"\; label="y"\; filenames="Y20072006116100061.png,Y20072006116100071.png"\; state="\{\{state\}\}">y</figure-callout>}}^2+{\mathrm{\&alpha;}}_2{\mathrm{the\; <figure-callout\; id="4"\; label="y"\; filenames="Y20072006116100061.png"\; state="\{\{state\}\}">y</figure-callout>}}^4+{\mathrm{\&alpha;}}_3{\mathrm{the\; y}}^6+{\mathrm{\&alpha;}}_4{\mathrm{the\; <figure-callout\; id="8"\; label="y"\; filenames="Y20072006116100081.png"\; state="\{\{state\}\}">y</figure-callout>}}^8+{\mathrm{\&alpha;}}_5{\mathrm{the\; y}}^{10}+{\mathrm{\&alpha;}}_6{\mathrm{the\; y}}^{12}+{\mathrm{\&alpha;}}_7{\mathrm{the\; y}}^{14}{+\mathrm{\&alpha;}}_8{\mathrm{the\; y}}^{16},$ Change the parameters of α ₁ to α ₅ in the equation so that the angle of light refracted by the LED lamp installed in the small hole 3 through the aspheric surface 4 can be 5°, 8°, 10°, 15°, 20°, 25°, 30°, 45°, 60°, 120° and other different angles to meet the needs of various places.

Furthermore, the mirror surface 2 can be made into a concave surface, so that the light emitted by the LED lamp can be well concentrated, so that the brightness can achieve a better effect; in addition, in order to meet the romantic mood of places such as bars, the mirror surface 2 can be made into a convex surface, The light emitted by the LED lamp is diverged, and its brightness is relatively dark, which relaxes people's nerves and meets the needs of entertainment. In addition, the mirror 2 can also be used as a common plane to meet the needs of the general population; the mirror 2 can also be densely covered with a plurality of parallel stripes, a plurality of convex balls or sand patterns, so that it emits The effect of light is various patterns, which have a decorative effect, and are especially suitable for lighting.
