Abstract

The utility model relates to the technical field of a lens, in particular to a high-power LED lens subassembly comprising a transparent upper cover and a plastic pedestal. The transparent upper cover is covered on the plastic pedestal; the plastic pedestal is provided with a through hole in which the lens is arranged; the transparent upper cover is also provided with a through hole, and the rim of the through hole of the transparent upper cover extends downwards and tightly presses the rim of the lens. As the plastic pedestal is provided with the through hole in which the lens is arranged, rays given out by an LED can be concentrated along a center, i.e. the whole light spot is more concentrative, and the illumination brightness is greater.

Description

The high-power LED lens assembly

Technical field:

The utility model relates to the lens technologies field, particularly the high-power LED lens assembly.

Background technology:

Because the LED consumed power is little, operating temperature is low, nontoxic, pollution-free, the life-span is long, possesses characteristics such as environmental protection, has become lighting source of new generation, along with emerging of high-power, high-brightness LED, the LED lighting engineering has obtained tremendous development.High-powered LED lamp has begun to be applied at aspects such as street lamp, Tunnel Lamp, shot-lights at present.In some field, need allow the LED hot spot more concentrated, brightness of illumination is bigger, and still, existing LED lamp socket does not possess this characteristics, thereby influences applying of LED.

The utility model content:

The purpose of this utility model is to provide the high-power LED lens assembly at the deficiencies in the prior art, when it cooperates great power LED to use, can make the LED hot spot more concentrated, and brightness of illumination is bigger.

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

It comprises transparent upper cover, plastic cement pedestal, and transparent upper cover is buckled on the plastic cement pedestal, offers through hole on the plastic cement pedestal, and lens are installed in the through hole, and transparent upper cover also offers through hole, and the edge of the through hole of transparent upper cover extends and compress the edge of lens downwards.

Offer three onesize through holes on the described plastic cement pedestal, the circle center line connecting of three through holes is formed equilateral triangle, and lens all are installed in each through hole.

Described lens middle part has the convex lens part, and the outer rim of convex lens part has annular female parts, and lens also form the cavity of ccontaining LED, and cavity is positioned at the below of convex lens part.

Form reference column on the described plastic cement pedestal, the through hole edge of described plastic cement pedestal has locating slot.

Described plastic cement pedestal upper surface forms fixed leg, and transparent upper cover is connected and fixed by fixed leg and plastic cement pedestal.

The beneficial effects of the utility model are, offer through hole and lens are installed on the plastic cement pedestal, and the light that LED sends is concentrated along the center, that is to say that to make whole hot spot more concentrated, and brightness of illumination is stronger.

Fig. 2 is that the A-A of Fig. 1 is to schematic diagram

Fig. 3 is a rearview of the present utility model

The specific embodiment:

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

The following stated only is a better embodiment of the present utility model, does not therefore limit protection domain of the present utility model.

See accompanying drawing 1,2,3, the utility model comprises transparent upper cover 10, plastic cement pedestal 20, and described plastic cement pedestal 20 upper surfaces form fixed leg 24, and transparent upper cover 10 is connected and fixed by fixed leg 24 and plastic cement pedestal 20; Transparent upper cover 10 is buckled on the plastic cement pedestal 20, offer through hole on the plastic cement pedestal 20, this through hole upper end is big and the lower end is little, lens 30 are installed in the through hole, transparent upper cover 10 also offers through hole, the edge of the through hole of transparent upper cover 10 extends and compresses the edge of lens 30 downwards, promptly fixes lens 30 by transparent upper cover 10.

Offer three onesize through holes on the described plastic cement pedestal 20, the circle center line connecting of three through holes is formed equilateral triangle, and lens 30 all are installed in each through hole, during use, also is combined with three LED, to strengthen result of use.

Described lens 30 middle parts have convex lens part 32, these convex lens part 32 purposes are to realize converging of light, the outer rim of convex lens part 32 has annular female parts 34, and lens 30 also form the cavity 36 of ccontaining LED, and cavity 36 is positioned at the below of convex lens part 32; These lens 30 patent applied fors are not given unnecessary details at this.

Form reference column 22 on the described plastic cement pedestal 20, the through hole edge of described plastic cement pedestal 20 has locating slot 26, during assembling, the LED front end places in the cavity 36 of lens 30, the rear end is by locating slot 26 location, the reference column 22 of plastic cement pedestal 20 inserts in the locating hole on the wiring board, thereby realizes the installation that cooperates of the utility model product and electronic circuit board.

Owing to adopted lens 30 on plastic cement pedestal 20, the light that LED sent can be concentrated to the center, when using three lens 30, can make the hot spot of LED more concentrated, and brightness of illumination is stronger.

The utlity model has the advantages such as result of use is better.
