Abstract

The utility model discloses a small LED (Light-Emitting Diode) spot lamp. A radiator base is cylindrical; a metal fixing plate of an aluminum-based circuit board is arranged on the bottom surface of the radiator base; radiating fins are arranged on the side wall of the radiator base; the aluminum-based circuit board is fixed on the metal fixing plate; lenses covers LEDs; a flat lampshade is pressed outside the lenses by virtue of a radiating ring in a connecting manner; the radiating ring is fixed on the radiating fins of the radiator base; holes, which are as many as the lenses, are formed in the flat lampshade, and the shape and the size of the bottom surfaces of the holes are matched with those of the lenses; a lamp body is arranged in a fixed ring; the side wall bottom of the lamp body is rotatably fixed on the side wall of the fixed ring by a pin roll; two or more clamping slots are formed in the upper end wall of the fixed ring; torsion springs are clamped in the clamping slots; one end of each torsional spring props against the inner wall of the fixed ring, the other end of each torsional spring extends to form a clamping frame, and the tail end of each torsional spring props against the outer wall of the fixed ring. The small LED spot lamp is convenient to mount and dismount, and the angle of the installed lamp body is adjustable.

Description

The little shot-light of a kind of LED

Technical field

The utility model relates to lighting field, relates to the little shot-light of a kind of LED.

Background technology

Raising along with people's living standard, people are also more and more higher to requirement attractive in appearance, with regard to lighting field, present light fixture product is well beyond the category of illumination, the research and development of more light fixture products and production is trend and the market demands such as attractive in appearance and decoration especially, under the ordering about of this market demand, the shot-light with magnificent mansion effect arises at the historic moment.It is more and more that little shot-light is used for the decorative applications of family's lamp pond, market or exhibition room.But adopt the shot-light power consumption of ordinary light source high, the thermal efficiency is high, and service life is short.In order to save electric energy, people adopt new light source led, and its energy consumption is low, but after the installation of existing LED shot-light, angle is fixing, can't satisfy the function of multi-angle irradiation.And it is installed needs complicated base, and its installation and removal are all inconvenient.

The utility model content

The purpose of this utility model solves the above-mentioned problems in the prior art exactly, provides a kind of installation and removal convenient, the adjustable little shot-light of LED of angle of lamp body after installation.

For achieving the above object, technical solution of the present utility model is: the little shot-light of a kind of LED, and it comprises lamp body and the retainer ring that is complementary with lamp body; Lamp body comprises foot of radiator, constant-current supply, several great power LEDs, fixed L ED and the aluminum-based circuit board that is electrically connected to LED, lens peace lampshade; The outer guide line of aluminum-based circuit board is connected with the output of constant-current supply, the outer guide line of the power input of constant-current supply; Foot of radiator is tubular, and there is the metal fixed head of aluminum-based circuit board its bottom surface, and radiating fin is arranged on sidewall; Aluminum-based circuit board is fixed on the metal fixed head, is covered with lens on LED, and flat lampshade also is crimped on outside lens by heat dissipating ring, and heat dissipating ring is fixed on the radiating fin of foot of radiator; Have on flat lampshade that number is identical with the lens number, bottom shape and size and lens bottom shape and the big or small hole that is complementary; Lamp body is placed in retainer ring, rotatably be fixed on the retainer ring sidewall by bearing pin bottom its sidewall, have two above buckling grooves on the retainer ring upper end wall, be connected with torsion spring in buckling groove, torsion spring one end withstands on the retainer ring inwall, the other end extends into the clamping frame, and this clamping frame end withstands on the retainer ring outer wall.

Radiating fin described above is all to a direction arc-shaped bend.

The utility model adopts LED to do light source, and its life-span is long, and power consumption is few; Itself and retainer ring rotatably are fixed on the retainer ring sidewall, so it can have the rotation of certain angle, can satisfy the requirement of multi-angle irradiation.Be fixed with torsion spring clamping frame on retainer ring, it can directly be connected in the lamp socket hole of reserving on the light fixture fixed head, mounts and dismounts all very convenient.

Description of drawings

Fig. 1 is STRUCTURE DECOMPOSITION figure of the present utility model;

Fig. 2 has fixed the structural representation of the aluminum-based circuit board of LED in the utility model.

The specific embodiment

The utility model will be further described below in conjunction with the drawings and specific embodiments:

As depicted in figs. 1 and 2, the present embodiment comprises lamp body and the retainer ring 10 that is complementary with lamp body.Lamp body comprises foot of radiator 4, constant-current supply 2, several great power LEDs 14, fixed L ED 14 and the aluminum-based circuit board 15 that is electrically connected to LED, the peaceful lampshade 7 of lens 6.The outer guide line of aluminum-based circuit board 15 is connected with the output of constant-current supply 2 by wire 1, the outer guide line 3 of the power input of constant-current supply 2.Foot of radiator 4 is tubular, and its bottom surface is fixed with the aluminium alloy fixed head 5 of aluminum-based circuit board, and radiating fin is arranged on sidewall.Radiating fin is all to a direction arc-shaped bend.Aluminum-based circuit board 15 is fixed on aluminium alloy fixed head 5, is covered with lens 6 on LED 14, and flat lampshade 7 also is crimped on outside lens 6 by heat dissipating ring 8, and heat dissipating ring 8 is fixed on the radiating fin of foot of radiator 4.Have on flat lampshade 7 that number is identical with lens 6 numbers, shape and the big or small hole 13 that is complementary of bottom shape and size and lens 6.Lamp body is placed in retainer ring 10, rotatably be fixed on retainer ring 10 sidewalls 9 by two bearing pins bottom its sidewall, have two buckling grooves on retainer ring 10 upper end wall, be connected with torsion spring 12 in buckling groove, torsion spring 12 1 ends withstand on retainer ring 10 inwalls, the other end extends into clamping frame 11, and these clamping frame 11 ends withstand on retainer ring 10 outer walls.
