Description

A kind of LED lens module

Technical field

The utility model belongs to the lens of LED light source lighting field, espespecially a kind of LED lens module.

Background technology

Along with LED light source replaces conventional light source gradually, the advantage of LED lighting is day by day admitted by people, such as LED is replaced to conventional lamp for field of street lamp lighting, can bring various advantages such as improving light efficiency, energy-saving and environmental protection.

But the LED light fixture of most is due to the restriction of structure, all there is the problem that heat radiation is difficult in major part, thereby cause the continuous rising of LED wick temperature, the rising of temperature is very large on the life-span impact of LED lamp, and finally shortens the life-span of wick, and finally causes wick to burn.Simultaneously, excess Temperature can cause the light fixture material to change, and affects the penetrating rate of light.Perfect condition is: the light fixture ventilation and heat is convenient, keeps as much as possible the temperature of wick in certain scope, thereby the light fixture material that may and guarantee that the minimizing wick burns can not reach the temperature of variation.Thereby extend the life-span of wick, guarantee the emergent ray intensity of light fixture.Can reduce the waste of luminous energy in addition.

The utility model content

In order to overcome the problems referred to above, this is novel provides a kind of LED lens module, the conglobate uniform light spots of the utility model energy shape, and light transmittance efficiency is good, and environmental protection realizes modularity production, and good heat dissipation is for convenience detach and install.

In order to achieve the above object, be achieved through the following technical solutions:

A kind of LED lens module, comprise polarizing body, the plane of incidence and exit facet, described polarizing body one end face is bottom surface, other end is end face, the bottom surface of described polarizing body arranges the pilot hole of an indent, the plane of incidence that the bottom surface of described pilot hole is described lens module, the exit facet that the end face of described polarizing body is described lens module.

Preferably, the curved surface of the sidewall of described polarizing body body for being rotated to form around axis by camber line.

Described lens module consists of three described polarizing body, and the line of centres of three described polarizing body forms an equilateral triangle, and the exit facet of three described polarizing body forms the exit facet of the integral type of whole module lens.

Further, the pilot hole of the cup type that described pilot hole is the cylinder formula, the central axis of described pilot hole and the central axes of described polarizing body.The bottom surface projection of the relative polarizing body of the described plane of incidence.

The surface of described exit facet is smooth flat.The outer setting positioning boss of described polarizing body, described positioning boss and described polarizing body integrated molding, arrange through hole on described positioning boss.On described positioning boss also with locating dowel and locking device.

The beneficial effects of the utility model are: this is novel is a kind of three-in-one lens module of making of the transparent material of PMMA.The major part of these lens is three polarizing body, and a pilot hole is designed in each polarizing body inside, and each pilot hole is for placing a LED luminous tube.The bottom of pilot hole is a round surface, and its degree of crook has determined the degree that converges of light irradiation and the lighting angle that final light is shot out.Its surface also becomes the plane of incidence, and light, from injecting here, enters in polarizing body, and the exposure pathways of light here deflects and converges.Simultaneously, the upper surface of polarizing body has formed the exit facet of light, and its exit facet is a smooth plane, guarantees that light penetrates with enough intensity.Secondly, also be evenly arranged three for fixing locking device in the surrounding of light fixture, thereby reduced the trouble that can be screwed, facilitated the detachable maintaining of light fixture.In addition, lens inside has also been designed three for locating the locating dowel of use, is conducive to the correct installation of lens.Finally, for heat radiation, designed the through hole of a circle around the polarizing body, except helping the outward appearance that the LED wafer better also can the decoration light fixture heat radiation.Adopt after said structure and light to be carried out to symmetrical refraction and reflection just can obtain strong light and penetrate from exit facet.Simultaneously, on every side around groove make the air-flow inside and outside light fixture unobstructed, guaranteed the heat-sinking capability of whole LED light fixture, improved greatly the temperature stability of lamp interior.This lamp socket adopts three-in-one design, makes compact overall structure simple, can reach higher illuminance.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is further described:

As depicted in figs. 1 and 2, a kind of LED lens module, this novel a kind of three-in-one lens module of making of the transparent material of PMMA.Comprise polarizing body 3, the plane of incidence 5 and exit facet 7, described polarizing body 3 one end faces are bottom surface 8, other end is end face, the bottom surface 8 of described polarizing body 3 arranges the pilot hole of an indent, the plane of incidence 5 that the bottom surface of described pilot hole is described lens module, the exit facet 7 that the end face of described polarizing body 3 is described lens module.As shown in Figure 2, the bottom of each pilot hole is a round surface, and its degree of crook has determined the degree that converges of light irradiation and the lighting angle that final light is shot out.Light, from the plane of incidence 5 is injected, enters the polarizing body 3 in cup, and the exposure pathways of light here deflects and converges.The exit facet 7 that the end face of described cup is described lens module, namely the upper surface of polarizing body 3 has formed the exit facet 7 of light, and its exit facet 7 is a smooth plane, guarantees that light penetrates with enough intensity.

Preferably, the curved surface of the sidewall of described polarizing body 3 for being rotated to form around axis by camber line.

Described lens module consists of three described polarizing body 3, and the line of centres of three described polarizing body 3 forms an equilateral triangle, and the exit facet 7 of three described polarizing body 3 forms the exit facet 7 of the integral type of whole module lens.
