Abstract
The utility model discloses an LED spotlight illumination lamp, which includes an LED light-emitting body and a control circuit, wherein a first convex lens and an objective lens are sequentially arranged in front of the LED light-emitting body; the LED light-emitting body is an aspheric surface convex lens; the objective lens comprises a concave lens and a second convex lens; and the concave lens is close to the first convex lens. After the technical scheme is adopted, firstly, the first convex lens is used for primary light focusing, then the objective lens is used for precise light focusing, all the light rays emitted by the LED light-emitting body are focused in a very narrow area, and the boundary of an illumination area and a non-illumination area is very clear.
Description
Technical field:
The utility model relates to a kind of LED spotlighting lamp.
Background technology:
Existing LED spotlighting lamp is in order to flock together light, the LED illuminator is located in the epoxy resin layer, utilize epoxy resin layer that light is reflected away, then in conjunction with the reflector of light fixture, the light that scatters to the rear is reflected away, utilize convex lens to carry out optically focused again, this LED spotlighting lamp spotlight effect is poor, and astigmatism is serious.
Summary of the invention:
The purpose of this utility model is in order to overcome the shortcoming of above-mentioned prior art, the extraordinary LED spotlighting of a kind of spotlight effect lamp to be provided.
For achieving the above object, the technical scheme that the utility model provides is: a kind of LED spotlighting lamp, include LED illuminator and control circuit, and be provided with first convex lens and object lens successively in the place ahead of LED illuminator.
First convex lens are the aspheric surface convex lens.
Described object lens are made of the concavees lens and second convex lens, and concavees lens are near first convex lens.
Described object lens are second convex lens.
After adopting technique scheme, at first first convex lens carry out first optically focused, and then carry out the accurate optically focused of secondary through object lens, and the light that the LED illuminator is sent all gathers in a very narrow and small zone, and the line of demarcation of field of illumination and non-field of illumination is very clear.
Description of drawings:
Fig. 1 is the structure chart of the utility model LED spotlighting lamp embodiment one;
Fig. 2 is the structure chart of the utility model LED spotlighting lamp embodiment two;
Fig. 3 is the structure chart of the utility model LED spotlighting lamp embodiment three.
The specific embodiment:
Now elaborate the utility model in conjunction with the accompanying drawings:
Embodiment one: as shown in Figure 1, the LED spotlighting lamp of present embodiment includes LED illuminator 1 and control circuit, be provided with first convex lens and object lens 3 successively in the place ahead of LED illuminator 1, first convex lens are the aspheric surface convex lens, and these first convex lens are plano-convex convex lens 2 simultaneously, these object lens 3 are made of the concavees lens 31 and second convex lens 32, and concavees lens 31 are near first convex lens.
Embodiment two: as shown in Figure 2, the LED spotlighting lamp of present embodiment includes LED illuminator 1 and control circuit, be provided with first convex lens and object lens 3 successively in the place ahead of LED illuminator 1, first convex lens are the aspheric surface convex lens, and these first convex lens are plano-convex convex lens 2 simultaneously, and these object lens 3 are second convex lens 33.
Embodiment three: as shown in Figure 3, compare with embodiment two, first convex lens of present embodiment are biconvex convex lens 4, and all the other structures are the same with embodiment two.
Above-mentioned is illustrative rather than determinate with reference to embodiment to the description that this LED spotlighting lamp carries out, and therefore in the variation and the modification that do not break away under the utility model general plotting, should belong within the protection domain of the present utility model.
