Abstract

The utility model discloses a condensing lens for a 12-bead combined LED (Light-Emitting Diode) project lamp, which relates to a lens for an LED lamp. The condensing lens comprises a lens body, wherein the lens body comprises 12 condensing bodies; the condensing bodies are cone-frustum-shaped; the large bottom end of each condensing body is an emergent surface of the condensing body; the emergent surfaces of the 12 condensing bodies are positioned on the same plane and construct the emergent surface of the condensing lens of the 12-bead combined LED project lamp; assembling holes for accommodating LEDs are formed at the small bottom ends of the condensing bodies; the assembling holes and hole walls opposite to the emergent surfaces of the condensing bodies are incident surfaces of the condensing bodies; 9 condensing bodies are arranged on an outer ring and are arranged into a circle; and 3 condensing bodies are arranged at a central position in the form of a triangle. The condensing lens has the beneficial effects that: the projection shapes of light spots are circular, the projection dispersing angles of light rays are 30 degrees, and light rays are projected in a centralized way; the illumination projection is uniform, and light colors can be changed by replacing LEDs of different colors; and the condensing lens has the advantages of low energy consumption, small size, long service life and low maintaining cost.

Description

A kind of collector lens of 12 pearl combined LED Projecting Lamps

Technical field

The utility model relates to the lens that are used for the LED lamp, refers to a kind of collector lens of 12 pearl combined LED Projecting Lamps especially.So-called 12 pearl combined types promptly refer to the luminescence unit (following agreement) that 12 light emitting diode combined form.

Background technology

Outside the building views such as profile, square, park, sub-district and various tourist attractions throw light on usually at present.Beautify the environment to reach, in the Landscape Lighting of rendered atmosphere and effect; What generally use is conventional lamp, and like incandescent lamp, fluorescent lamp, high-pressure sodium lamp, metal halide lamp, high-pressure mercury lamp and low-pressure sodium lamp etc., the major defect of this type light fixture is to use the life-span short; Light efficiency is low; Energy consumption is high, and photochromic control is difficult, and volume is big and maintenance cost is high.Also there is a certain distance in this with the requirement that country advocates energy-saving and emission-reduction.

Summary of the invention

The utility model is intended to overcome the above-mentioned deficiency of prior art, and meeting the market requirement provides a kind of collector lens of 12 pearl combined LED Projecting Lamps.Its characteristics: the rounded projection of projection shape of hot spot, light is concentrated projection;

illumination projection evenly, photochromic can conversion; light source adopts the LED luminous tube, and energy consumption is low, volume is little, long service life and maintenance cost are low.

For this reason, the collector lens of a kind of 12 pearl combined LED Projecting Lamps of the utility model adopts following technical scheme:

The collector lens of a kind of 12 pearl combined LED Projecting Lamps of structure the utility model; Comprise lens body; Said lens body comprises 12 condensing bodies; Said condensing body is circular cone shape, and the big bottom of its condensing body is the exit facet of condensing body, and the exit facet of 12 condensing bodies is positioned at same plane and constitutes a kind of exit facet of collector lens of 12 pearl combined LED Projecting Lamps; The little bottom of its condensing body is shaped on the pilot hole that light emitting diode is installed, and light emitting diode is installed on said pilot hole, and the hole wall that the exit facet of pilot hole and said condensing body is relative is the plane of incidence of said condensing body; 12 said condensing bodies are arranged like this: arrange 9 said condensing bodies in the outer ring and be arranged in circle, 3 said condensing bodies are triangularly arranged in the centre.

Technique scheme is further set forth:

Be shaped on the assembling step on the lens body, so that lens body and installation carrier are equipped.

Be shaped on the reference column that strengthens the lens body mechanical strength on the lens body, said reference column is column, and the short transverse of its reference column is consistent with the short transverse of said condensing body, and reference column is positioned at the position, space between the condensing body of inner of lens body.

The concrete shape of the plane of incidence designs according to the crevice projection angle that optical characteristics and this projection source of light emitting diode requires to reach.

Lens body is made with transparent material, like plastic cement PMMA etc.

The beneficial effect of the utility model is: one of which, and the rounded projection of projection shape of hot spot, ray cast is scattered and is angle 30 degree, and light is concentrated projection; Its two, illumination projection evenly photochromicly can realize conversion through the LED wick (being light emitting diode) of more changing different colours; Its three, light source adopts light emitting diode, energy consumption is low, volume is little, long service life and maintenance cost are low.

The specific embodiment

Below, introduce the specific embodiment of the utility model in conjunction with accompanying drawing.

Extremely shown in Figure 3 like Fig. 1; The collector lens of a kind of 12 pearl combined LED Projecting Lamps of the utility model comprises lens body 1, and said lens body 1 comprises 12 condensing bodies 2 (shape of each condensing body 2 and consistent size); Said condensing body 2 is circular cone shape; The big bottom of its condensing body 2 is the exit facet of condensing body 2, and the exit facet of 12 condensing bodies is positioned at same plane and constitutes a kind of exit facet of collector lens of 12 pearl combined LED Projecting Lamps, and the little bottom of its condensing body 2 is shaped on the pilot hole 3 that light emitting diode is installed; Light emitting diode is installed on said pilot hole 3, and pilot hole 3 is the plane of incidence 4 of condensing body with the relative hole wall of exit facet of condensing body; 12 said condensing bodies 2 are arranged like this: arrange 9 said condensing bodies 2 in the outer ring and be arranged in circle, 3 said condensing bodies 2 are triangularly arranged in the centre.

Be shaped on assembling step 5 on the lens body 1, so that lens body 1 is equipped with the installation carrier.

Be shaped on the reference column 7 that strengthens lens body 1 mechanical strength on the lens body 1; Said reference column 7 is column; The short transverse of its reference column 7 is consistent with the short transverse of said condensing body 2, and reference column 7 is positioned at the position, space of 2 of the condensing bodies of 1 inner of lens body.In the present embodiment, reference column 7 is 3 and Boulez triangular in shape.

The concrete shape of the plane of incidence 4 comes 1 usefulness transparent material to make according to the crevice projection angle that the optical characteristics of light emitting diode and this projection source require to reach, like plastic cement PMMA etc.

The above only is the preferred embodiment of the utility model, is not that the technical scope of the utility model is done any restriction.The technical staff of the industry; Under the inspiration of present technique scheme; Can make some distortion and revise, every technical spirit according to the utility model all still belongs in the scope of the utility model technical scheme above any modification, equivalent variations and modification that embodiment did.
