Abstract

The utility model discloses an LED condenser cup, which comprises a cup with a parabolic inner surface and a cup front end with a transparent cover. The utility model is characterized by that the a condensing lens is arranged in the cup and around the center axis; internal of the condensing lens comprises a cylindrical hole whose diameter slidedly acts according to the LED diameter; and the cup, the front cover and the condensing lens are made of injection molded, transparent plastic whole pieces. In addition, the front cover center has a condensing lens. The utility model has advantages in that: simple in structure and production processes, good in condensing effect and applicable to various lamps.

Description

The LED prefocus cup

Technical field

The utility model relates to a kind of Lamp cup, especially a kind of LED optically focused Lamp cup.

Background technology

Traditional LED prefocus cup comprises that as shown in Figure 1 an inner surface is paraboloidal cup 2 and the transparent protecgulum 3 that is assemblied in cup 2 front ends, and LED1 is contained in the bottom center of cup, and the parabola of depending cup 2 inner surfaces alone that it sends penetrates after with its optically focused.The defective of this lampshade is: 1, cup is after injection mo(u)lding, and the parabola of its inner surface just can use after must electroplating reflector layer; 2, protecgulum 3 must be equipped in addition, in order to assemble the protection eyeglass of protecgulum 3, also must be equipped with the part 4 of assembling protection eyeglass protecgulum, and this part 4 also must have the structure that connects with cup 2, for example screw thread or other connection form; 3, the installation site of LED is subjected to the restriction of parabolic shape, and its position is fixed, and can not regulate, so when the shape of LED and size variation, it is best that the effect of optically focused is difficult to reach.4, as seen from the above analysis, this complex structure, processing technology is loaded down with trivial details, certainly will cause the increasing of manufacturing cost.

Summary of the invention

The purpose of this utility model is the deficiency that overcomes above-mentioned prior art, provides a kind of simple in structure, with low cost, LED optically focused Lamp cup that spotlight effect is splendid again or title LED collector lens.

Above-mentioned purpose adopts following technical scheme just can realize: the LED prefocus cup of the technical program is the same with prior art to comprise that an inner surface is the transparent protecgulum of paraboloidal cup and cup front end, and its improvement is also to be provided with a collector lens around its center line in cup; The inside center of this collector lens comprises the cylindrical hole that a diameter matches with the external diameter of LED; And said cup, protecgulum and collector lens are single injection-molded, transparent plastic monoblock.

During use, a led light source is loaded in the interior cylindrical hole of cup, and its light that sends penetrates stronger light again behind the common optically focused of parabolic and collector lens.And the installation site of led light source can also make its position be in best point by the mobile adjusting in this cylindrical hole.

Another better technical scheme is on the basis of technique scheme, to set up the lens of a collector lens or different light efficiencies at the center of said protecgulum.

During use, a LED is loaded in the interior cylindrical hole of cup, and its light that sends penetrates the strongest light again behind the common optically focused of parabolic and two collector lenses.And the installation site of LED can also make it be in best location point by the mobile adjusting in this cylindrical hole.

By above analysis as can be seen, the utility model has the advantages that:

1, prefocus cup of the present utility model can single injection-molded, has saved and has electroplated and the operation of equipped protecgulum, and therefore simple in structure, cost reduces greatly;

2, this prefocus cup makes light intensity can improve about 30% through 2 times or 3 optically focused of parabolic and single convex lens or biconvex lens;

3, only with the lens design that changes LED prefocus cup front end outer surface, hot spot can change arbitrary shape

4, the prefocus cup of single injection-molded is a transparent substance, and is glittering and translucent very attractive in appearance;

5, the utility model is applied widely, and available its made various LED light fixtures, for example LED desk lamp, LED shot-light, stage lighting, Landscape Lamp, the head lamp that flashlight, industrial and mineral are used, advertising lamp etc.

The utility model is more clear to be understood with being convenient in order to make, and below by drawings and Examples it is described further.

The specific embodiment

Embodiment 1, referring to Fig. 2, Fig. 3.The prefocus cup of present embodiment comprises that an inner surface is the cup 3 of parabola 35 and the transparent protecgulum 33 of cup 3 front ends, and also is provided with a collector lens 32 around its center line in cup 3; The inside center of this collector lens 32 comprises the cylindrical hole 34 of the external diameter sliding fit of a diameter and LED1; And said cup 3, protecgulum 33 and collector lens 32 are single injection-molded, transparent plastic monoblock.

Embodiment 2, referring again to Fig. 2, Fig. 4.The prefocus cup of present embodiment comprises that an inner surface is parabolic 45 cup 4 and is assemblied in the transparent protecgulum 43 of cup 4 front ends, and also is provided with a collector lens 42 around its center line in cup 4; The inside center of this collector lens 42 comprises the cylindrical hole 44 of the external diameter sliding fit of a diameter and LED1; Simultaneously also be provided with a collector lens 46 at the center of said protecgulum 43; And said cup 4, protecgulum 43 and collector lens the 46, the 42nd, single injection-molded, transparent plastic monoblock.

Embodiment 3-6 is referring to Fig. 2, Fig. 7 and Fig. 8.These embodiment are on the basis of the

foregoing description
