CN202675068U - Light-emitting diode (LED) spot light - Google Patents

Abstract

The utility model provides a light-emitting diode (LED) spot light which comprises a lamp holder; the lamp holder is in a circular shape; the bottom of the lamp holder is provided with radiating fins which are integrated and are uniformly distributed along a central shaft; clamp positions are arranged on the side walls of both sides of the lamp holder; and the lamp positions are assembled on the lamp holder through springs. After the scheme is adopted, the luminance can be stronger due to the adoption of three high-power LED lamp beads; after the radiating fins which are integrated and uniformly distributed are adopted, the heat dissipation speed is higher, and the service life of the LED spot light is greatly prolonged; and the clamp positions on both sides are convenient to install.

Description

A kind of LED shot-light

Technical field

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

Background technology

Initial LED is as the indication light source of instrument and meter, and various photochromic LED were widely applied in traffic lights and large-area displays screen afterwards, had produced good economic benefit and social benefit.Take 12 inches red traffic lights as example, be to adopt the long-life originally in the U.S., 140 watts of incandescent lamps of low light efficiency are as light source, and it produces the white light of 2000 lumens.Behind Red lightscreening plate, light loss 90%, the ruddiness of only remaining 200 lumens.And in newly-designed lamp, Lumileds company has adopted 18 red LED light sources, comprises circuit loss, and power consumption is 14 watts altogether, can produce same light efficiency.Automobile signal light also is the key areas that led light source is used.For general illumination, people more need the light source of white.The LED that emitted white light in 1998 succeeds in developing.This LED is packaged together GaN chip and yttrium aluminium garnet YAG to make.GaN chip blue light-emitting λ p=465nm sends sodium yellow after the YAG fluorescent material that contains Ce3+ that Wd=30nm, high temperature sintering make is subjected to this blue-light excited and penetrates peak value 550nm.The blue-ray LED substrate is installed in the bowl-type reflection cavity, covers to be mixed with the thin resin layer of YAG, about 200-500nm.The blue light part that the LED substrate sends is absorbed by fluorescent material, and the yellow light mix that another part blue light and fluorescent material send can obtain getting white light.Now, for the InGaN/YAG White LED, by the chemical composition that changes YAG fluorescent material and the thickness of regulating phosphor powder layer, can obtain the white light of all kinds of colour temperature 3500-10000K.Thisly obtain the method for white light by blue-ray LED, simple structure, with low cost, technology maturity is high, therefore use at most.But, this caloric value when work of LED lamp is larger, produced thus larger light decay, simultaneously also shortened the service life of LED lamp, thus limited to a certain extent the range of application of LED lamp at lighting field, because brightness and the underpower of single led light source, can not just use as illumination, so existing LED lamp has generally all been assembled a plurality of led light sources, the number of the led light source of assembling is more, and the brightness of made LED lamp and power also will be higher.But the heat that is produced by a plurality of led light sources can not dissipate effectively, so that the temperature of the shell of lamp can be higher, the people has hot danger at a touch; Moreover the temperature height also makes the lamp ratio be easier to damage.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of simple in structure, LED shot-light that radiating rate is fast is provided.

For achieving the above object, technical scheme provided by the utility model is: a kind of LED shot-light, and it includes lamp socket, lamp socket is circular, its bottom is integrated along the equally distributed fin of central shaft, and lamp socket both sides sidewall is provided with screens, and screens is assemblied on the lamp socket by spring.

Described fin is arc, evenly distributes along central axis.

Described screens front end is coated with plastic pad.

Three large-power LED light beads are installed in the described lamp socket.

The utility model adopts three large-power LED light beads can make illuminance stronger after having adopted such scheme, and behind employing integral type and the equally distributed fin, radiating rate is faster, has greatly prolonged the service life of LED shot-light, and the screens of both sides is convenient installs.

Description of drawings

Fig. 1 is overall structure schematic diagram of the present utility model.

Fig. 2 is heat radiating fin structure schematic diagram of the present utility model.

The specific embodiment

The utility model is described in further detail below in conjunction with institute's drawings attached, preferred embodiment of the present utility model is: referring to accompanying drawing 1 and accompanying drawing 2, the described LED shot-light of present embodiment includes lamp socket 1, lamp socket 1 is circular, bottom is one-body molded that several fin 2 are arranged for it, fin 2 is arc, is evenly distributed on the lamp socket 1 along central axis; Lamp socket 1 both sides sidewall is provided with screens 3, and screens 3 is assemblied on the lamp socket 1 by spring 4, and screens 3 front ends are coated with plastic pad 5, and the lamp pearl 6 in the lamp socket 1 is three, and three lamp pearls 6 are evenly distributed in the lamp socket 1 along central axis.Adopt three high-power lamp pearls 6 can make illuminance stronger, behind employing integral type and a plurality of equally distributed fin 2, radiating rate is faster, has greatly prolonged the service life of LED shot-light, screens 3 convenient installations of both sides.

The embodiment of the above is the preferred embodiment of the utility model only, is not to limit practical range of the present utility model with this, so the variation that all shapes according to the utility model, principle are done all should be encompassed in the protection domain of the present utility model.
