Abstract

A light-emitting diode (LED) spotlight comprises a lamp base and a lamp holder arranged in the lamp base rotatably, wherein the lamp holder comprises a lampshade and a lens embedded into the lampshade, a circuit board is arranged in the lamp base, and an LED capable of corresponding to the lens is installed on the circuit board. The LED spotlight is characterized in that a positioning piece is further arranged on the circuit board and provided with a through hole for the LED to penetrate through, and a cavity capable of limiting the positioning piece in a clamping-matching mode is formed at the bottom of the lampshade. The positioning piece is arranged on the circuit board, the cavity is arranged at the bottom of the lampshade, so that when the positioning piece and the circuit board serve as a whole to be installed in the lampshade, matching can be performed with the outer diameter of the positioning piece and the inner diameter of the cavity of the lampshade as the standard, the positioning piece and the lampshade are finish turning parts, the processing accuracy is ensured easily, central consistency of the lens and the LED is ensured effectively, and good illumination effect can be obtained.

Description

A kind of LED shot-light

Technical field

The utility model relates to a kind of LED shot-light.

Background technology

In common focusing class LED shot-light, install consistent for guaranteeing collector lens with LED light-emitting diodes tube hub, to reach good lighting effect, in general, should there be enough spaces to come the mounted lens support in the inside of product, perhaps collector lens make pillar and wiring board the hole as the location, thereby the center that reaches collector lens and light emitting diode is consistent.

But, present LED light fixture product with compact structure, all just rely on the external diameter of wiring board or screw hole as positioning datum when usually installing, yet, in actual production processing, the external diameter of wiring board or the tolerance of screw hole are larger, can't accomplish higher machining accuracy, this just so that in the assembling process collector lens and LED light emitting diode just to be difficult to reach both center consistent, do not reach good illuminating effect.

The utility model content

Technical problem to be solved in the utility model is to provide a kind of simple in structure and can effectively guarantee the conforming LED shot-light in center of collector lens and LED light emitting diode for above-mentioned prior art present situation.

The utility model solves the problems of the technologies described above the technical scheme that adopts: a kind of LED shot-light, include lamp socket and be arranged at rotationally the interior lamp holder of this lamp socket, described lamp holder includes lampshade and is embedded at the interior lens of this lampshade, be provided with circuit board in the described lamp socket, on this circuit board be equipped with can and LED light emitting diode corresponding to described lens, it is characterized in that: also be fixedly installed a spacer on the described circuit board, offer the through hole that can supply described LED light emitting diode to pass on the described spacer, the bottom of described lampshade is formed with to block mutually with described spacer joins spacing vestibule.

In order to realize Fast Installation, and guarantee reliability of positioning and the flexibility of spacer, as preferably, it is dolioform that described spacer can be, this spacer has two relatively and establishes and be circular-arc curved surface, described vestibule then correspondingly is a circular hole, and the distance between two curved surfaces of described spacer is suitable with the aperture of described circular hole.Because the vestibule of lampshade bottom is rounded, and spacer has two curved surfaces of relatively establishing, it is suitable that the shape of curved surface just is being better than the rounded face of vestibule, so that lampshade is when assembling, be fastened on the spacer on can be in any direction, and the vestibule of assurance lampshade bottom and the spacing cooperation between the spacer, convenient assembling.

In order to improve the thermal diffusivity of light fixture, as further preferred, described circuit board bottom also is connected with heat sink.

Compared with prior art, the utility model has the advantage of: at circuit board a spacer is set, this spacer offers through hole, the LED light emitting diode can be sheathed within the through hole, simultaneously offer vestibule in the bottom of lampshade, when spacer and circuit board assemblies are packed in the lampshade as an integral body, can cooperate as benchmark with the external diameter of spacer and the vestibule internal diameter of lampshade, and, spacer (usually injection mo(u)lding) and lampshade are as finish turning spare, and both precision are higher comparatively speaking, and machining accuracy easily guarantees, effectively guarantee the center uniformity of lens and LED light emitting diode, can obtain preferably lighting effect.

The specific embodiment

Embodiment is described in further detail the utility model below in conjunction with accompanying drawing.

Such as Fig. 1～shown in Figure 4, the present embodiment is a kind of LED shot-light, and this LED shot-light includes lamp socket 1 and is arranged at rotationally lamp holder in this lamp socket 1, wherein, lamp holder comprises lampshade 2, deck 3 and lens 4, wherein, deck 3 is placed in the lamp socket 1, and lens 4 are embedded in the deck 3; Be provided with circuit board 5 in the lamp socket 1, circuit board 5 bottoms are connected with heat sink 6, and being equipped with on the circuit board 5 can the LED light emitting diode 7 corresponding with lens 4.

The lens 4 of the present embodiment adopt collector lens, the center uniformity of lens 4 and LED light emitting diode 7 in order to guarantee to install, the present embodiment is fixedly installed a spacer 8 at circuit board 5, spacer 8 can be fixedly connected on the circuit board 5 by variety of way, spacer 8 is dolioform, this spacer 8 has two relatively and establishes and be circular-arc curved surface, also offers the through hole 81 that capable for LED light emitting diode 7 passes on the spacer 8; The bottom of lampshade 2 is formed with to block mutually with spacer 8 joins spacing vestibule 21, and vestibule 21 is a circular hole, and the distance between two curved surfaces of spacer 8 is suitable with the aperture of circular hole.

During installation, spacer 8 is fixed on the circuit board 5, the through hole 81 of spacer 8 just in time is sheathed on the LED light emitting diode 7, lens 4 and lampshade 2 assemblies have been fixed in one in advance, with the circuit board 5 that is fixed with spacer 8 lampshade 2 bottoms of packing into, the vestibule 21 of lampshade 2 bottoms and spacer 8 cooperate, both assembling and positioning benchmark are vestibule 21 inwalls of lampshade 2 and the external diameter of spacer 8, lampshade 2 inwalls of the present embodiment are finishing size, and inwall is the installation location dimension of lens 4, and spacer 8 is adopting moulding, its accurate to dimension is high, vestibule 21 by spacer 8 and lampshade 2 cooperates the uniformity that can guarantee LED light emitting diode 7 and lens 4 centers, improves lighting effect.
