Abstract

The utility model relates to the field of lighting lamps, particularly to a spot lamp. The novel spot lamp comprises a bulb and a power source plug wire, wherein the bulb is screwed on the clamp groove in a lampshade through threads, and the power source plug wire is electrically connected to the back of the lampshade. A circuit board is arranged above the thread body of the bulb and in the lampshade, a plurality of LEDs are arranged on the circuit board, an annular clamp edge is arranged at the periphery of the development end of the lampshade, an optical lens is clamped on the clamp edge through the annular clamp head of the optical lens, and the optical lens adopts a Fresnel lens with Fresnel stripes distributed in a ladder-shaped way in the optical lens. The LED spot lamp with simple structure and high performance price ratio not only has the advantages of low temperature and long service life of the LED, but also overcomes the defect of poor condensation directivity of the LED.

Description

A kind of LED shot-light

Technical field

The utility model relates to field of illuminating lamps, relates in particular to a kind of shot-light.

Background technology

In daily productive life, the lamp applications of illumination is very wide.Lighting has generally included incandescent lamp, fluorescent lamp, desk lamp, neon light, street lamp or the like.And shot-light is a kind of lighting wherein.It mainly is to be used for special lighting field, and it is a kind of light fixture of height optically focused, and its light irradiation has can specify specific objective.It also can be applied to general room lighting field, such as emphasizing that certain is very flavoursome or the place of new meaning being arranged very much, as stage or dining room etc.But existing illuminator needs big illumination lightness and optically focused, generally adopts high-pressure halogen lamp or gases at high pressure lamp etc.But along with the development of LED technology, the great power LED technology of high brightness is also constantly progressive, can satisfy the lighting requirement of shot-light, and it has advantages such as temperature is low, the life-span is long, is that traditional shot-light is beyond one's reach.But it is applied to also defectiveness of shot-light, and the optically focused directionality that is exactly LED is not good.Therefore, still not having comparatively perfect LED shot-light lighting engineering at present uses.

The utility model content

At the problem of above-mentioned proposition, the utility model proposes a kind of LED shot-light, the advantage that realized not only that the temperature of LED is low, the life-span is long has overcome the not good deficiency of optically focused directionality of LED simultaneously, is a kind of simple in structure, shot-light that cost performance is higher.

The technical solution adopted in the utility model is as follows:

LED shot-light of the present utility model is combined on the bulb of lampshade inner card cage and is electrically connected and power supply plug wire in described lampshade back constitutes by screw thread.One circuit board is set within the top of the threaded body of described bulb and the cloche, circuit board is provided with a plurality of LED, one circle of the exploitation end of described lampshade is provided with an annular shelf, annular dop by the optical lens camera lens on the edge clipping engages an optical lens camera lens, and described optical lens camera lens is the Fresnel Lenses with Fresnel striped that the internal step scalariform distributes.

Further, described LED quantity is 8, rounded being symmetrically distributed on the described circuit board.

The utility model adopts as above technical scheme, the LED lamp is used for shot-light illumination, has not only realized the advantage that the temperature of LED is low, the life-span is long, simultaneously the setting by Fresnel Lenses, having overcome the not good deficiency of optically focused directionality of LED, is a kind of simple in structure, shot-light that cost performance is higher.

Description of drawings

Fig. 1 is a schematic diagram of the present utility model;

Fig. 2 is the schematic diagram of optical lens camera lens of the present utility model.

The specific embodiment

Now with the specific embodiment the utility model is further specified in conjunction with the accompanying drawings.

Consult illustrated in figures 1 and 2ly, LED shot-light of the present utility model is combined on the bulb 10 of lampshade 20 inner card cages and is electrically connected and power supply plug wire 30 in described lampshade 20 backs constitutes by screw thread.One circuit board 103 is set within the top of the threaded body 101 of described bulb 10 and the cloche 102, circuit board 103 is provided with a plurality of LED104, one circle of the exploitation end of described lampshade 20 is provided with an annular shelf 201, by the annular dop 402 engagings one optical lens camera lens 40 of optical lens camera lens 40, described optical lens camera lens 40 is Fresnel Lenses with Fresnel striped 401 that the internal step scalariform distributes on the edge clipping 201.

Preferably, described LED104 quantity is 8, rounded being symmetrically distributed on the described circuit board 103.

The bulb external form of LED bulb of the present utility model and common shot-light is consistent, just adopt the filament or the negative electrode that are arranged at a plurality of great power LEDs replacement bulbs on the circuit board, therefore anti-vibration resistance is better, and has possessed the lower calorific value of LED and the advantage of long life.Utilize the optical lens of the Fresnel Lenses of single injection-molded, not only the light of LED had good directionality with assembling as shot-light, also reduce cost simultaneously and with the lampshade sealing after be beneficial to the dust and moisture of shot-light.

Although specifically show and introduced the utility model in conjunction with preferred embodiment; but the those skilled in the art should be understood that; in the spirit and scope of the present utility model that do not break away from appended claims and limited; can make various variations to the utility model in the form and details, be protection domain of the present utility model.
